Answer:
40 square feet.
Step-by-step explanation:
We have been given that a square foot wall of space needs 1/8 quart of paint. Terrence has 7 quarts of paint, but uses 2 quarts to paint a pipe.
The amount of paint that left will be 5 quarts (7-2=5).
To find the area of wall that can be painted with the rest of paint, we will divide amount of left paint by the amount used to paint one square foot of wall.
[tex]\text{The number of square feet that can be painted with rest of paint}=5\div \frac{1}{8}[/tex]
Dividing a number by a fraction is same as multiplying the number by the reciprocal of fraction.
[tex]\text{The number of square feet that can be painted with rest of paint}=5\times \frac{8}{1}[/tex]
[tex]\text{The number of square feet that can be painted with rest of paint}=5\times 8=40[/tex]
Therefore, 40 square feet of wall can be painted with the rest of the paint.
Terrence can paint 40 square feet of wall with the rest of the paint.
Explanation:To find out how many square feet of wall Terrence can paint with the rest of the paint, we need to subtract the amount of paint he used to paint the pipe from the total amount of paint he has. Terrence has 7 quarts of paint and used 2 quarts to paint the pipe, so he has 7 - 2 = 5 quarts of paint left. Since 1/8 quart of paint is needed for 1 square foot of wall, we can find out how many square feet of wall Terrence can paint by dividing the amount of paint he has left by the amount of paint needed for 1 square foot:
Number of square feet of wall Terrence can paint = (5 quarts) / (1/8 quart per square foot) = (5 quarts) × (8/1) square feet per quart = 40 square feet.

Calculate the area of trapezium CDEF.
We are given the two bases of the trapezium:
[tex] ED = 5,\qquad AB = 9 [/tex]
The formula for the area of the trapezium is
[tex] A = \dfrac{(B+b)h}{2} [/tex]
So, we only need to figure out the length of the height EF.
We know that FA+EF = 11. Also, we're given that the perimeter of ABCF is 28, which means
[tex] 2AB+2FA = 28 \iff 2\cdot 9 + 2FA = 28 \iff 2FA = 10 \iff FA = 5 [/tex]
So, we can deduce
[tex] EF = 11-FA = 11-5=6 [/tex]
And so we're ready to use the solving formula:
[tex] A = \dfrac{(5+9)\cdot 6}{2} = \dfrac{14\cdot 6}{2} = 7\cdot 6 = 42 [/tex]

A swimming pool is filled with 8,520 gallons of water. The pool begins to drain at a rate of 12 gallons per minute. Which equation can be used to find the number of minutes, m, it will take for the pool to be half full?
Answer:
it will take 355 minutes or 5 hours 55 minutes to be half empty. An equation would be (8,520 ÷ 2) ÷12 = m
Step-by-step explanation:
First, you must find half of 8,520 to see how much will half to be left in the pool for the problem. 8,520÷2=4,260
Second, you have to divide 4,260 by twelve to find out how many minutes it will take to become half empty.
Good luck ;b
Answer:
The equation that can be used to find the number of minutes that it would take for the pool to be half full is:
M = (8,520 / 2) / 12
As a result, it would take 355 minutes for the pool to be half full.
Step-by-step explanation:
First, we must determine how many gallons the half-filled pool has. If completely filled it has a capacity of 8,520 gallons, half-filled this should have a capacity of 8,520 / 2, that is, 4,260 gallons.
Then, we must divide this amount of gallons by the gallons that are lost per minute, that is, 4,260 / 12. In this way we get the amount of minutes it takes for the pool to reach half its capacity.
Then, the equation to determine the amount of minutes (M) it takes for the pool to reach half its capacity is: M = (8,520 / 2) / 12

Casey buys a bracelet. She pays for the bracelet and pays \$0.72$0.72 in sales tax. The sales tax rate is 6\%6%. What is the original price of the bracelet, before tax?
Answer:
The original price of the bracelet before tax is $12.
Step-by-step explanation:
Let us assume that the original price of the bracelet be x.
As given
Casey buys a bracelet.
She pays for the bracelet and pays $0.72 in sales tax .
The sales tax rate is 6% .
6% is written in the decimal form.
[tex]= \frac{6}{100}[/tex]
= 0.06
Than the equation becomes
x × 0.06 = 0.72
0.06x = 0.72
[tex]x = \frac{0.72}{0.06}[/tex]
x = $12
Therefore the original price of the bracelet before tax is $12.

Levi needs to write 263,000,700,000 in scientific notation. He says that the exponent in the second factor is negative. Is Levi's reasoning correct? Use the drop-down menus to explain your answer. The exponent would be blank because the number Levi wrote in scientific notation is blank one.
Answer : No, levi's reasoning is incorrect. The correct answer is, [tex]2.63\times 10^{11}[/tex]
Step-by-step explanation :
Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power. The numerical digit lies between 0.1.... to 9.9.....
For example :
5000 is written as [tex]5.0\times 10^3[/tex]
889.9 is written as [tex]8.899\times 10^{-2}[/tex]
In this examples, 5000 and 889.9 are written in the standard notation and [tex]5.0\times 10^3[/tex] and [tex]8.899\times 10^{-2}[/tex] are written in the scientific notation.
If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.
As we are given the 263,000,700,000 in standard notation.
Now converting this into scientific notation, we get:
[tex]\Rightarrow 263,000,700,000=2.63\times 10^{11}[/tex]
As, the decimal point is shifting to left side, thus the power of 10 is positive.
Hence, the correct answer is, [tex]2.63\times 10^{11}[/tex]
Answer:
No. He answered incorrectly. The correct scientific notation of the number will be [tex]2.630007\times10^{11}[/tex].
Step-by-step explanation:
Levi wants to write 263,000,700,000 in the scientific notation.
In scientific notation, the number is represented by a numerical value between 1 and 9.99...., multiplied by power of 10.
The given number can be written as,
[tex]263,000,700,000=2.630007\times100,000,000,000\\263,000,700,000=2.630007\times10^{11}[/tex]
Thus, in scientific notation, the given number can be written as [tex]2.630007\times10^{11}[/tex].
Here, the numerical value is 2.630007 and power of 10 is [tex]10^{11}[/tex].
Now, the power of 10 is 11 which is positive. So, Levi has answered incorrectly.

Decide if the function is an exponential growth function or exponential decay function, and describe its end behavior using limits. Y=7^-x
Answer:
Exponential Decay
Its end behavior on the left is as follows as x approaches negative infinity y approaches positive infinity. Its end behavior on the right is as follows as x approaches positive infinity y approaches negative infinity.
Step-by-step explanation:
We can graph the function by graphing two points when x=0 and x=1.
x=0 has [tex]y=7^{-x} =7^{0} =1[/tex]
x=1 has y=[tex]7^{-x} =7^{-1} =\frac{1}{7}[/tex]
This function starts with higher output values and decreases over time. This is Exponential Decay. Its end behavior on the left is as follows as x approaches negative infinity y approaches positive infinity. Its end behavior on the right is as follows as x approaches positive infinity y approaches negative infinity.
Using limits, it is found that since [tex]\lim_{x \rightarrow \infty} f(x) < \lim_{x \rightarrow -\infty} f(x)[/tex], it is an exponential decay function, as it starts at infinity and ends at 0.
How we use limits to classify an exponential function as growth or decay?An exponential function is modeled by:
[tex]f(x) = ab^x[/tex].
Then:
If [tex]\lim_{x \rightarrow \infty} f(x) < \lim_{x \rightarrow -\infty} f(x)[/tex], it is exponential decay.If [tex]\lim_{x \rightarrow \infty} f(x) < \lim_{x \rightarrow -\infty} f(x)[/tex], it is exponential growth.In this problem, the function is:
[tex]y = 7^{-x}[/tex]
Hence:
[tex]\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} 7^{-x} = 7^{-\infty} = \frac{1}{7^{\infty}} = 0[/tex]
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} 7^{-x} = 7^{\infty} = \infty[/tex]
Hence, it is exponential decay, as it starts at infinity and ends at 0.

now, we can plug a=4
[tex]\lim_{x \to 4} f(x)=\lim_{x \to 4}\frac{4-4}{4+5}[/tex]
[tex]\lim_{x \to 4} f(x)=0[/tex]
Functional value:
We can plug x=4 into f(x)
[tex]f(4)=\frac{4-4}{4+5}[/tex]
[tex]f(4)=0[/tex]
So, we can see that
[tex]\lim_{x \to 4} f(x)=f(4)=0[/tex]

does the system have one solution, no solution, or infinitely many? Use your substitution to justify your answer
x+2y= -10
-x+2y= -2
Answer: It has one solution. The solution is (x,y) = (-4,-3)
Add up the equations doing so straight down
x + -x = 0x = 0 so the x terms go away
2y + 2y = 4y
-10 + (-2) = -12
We end up with 4y = -12 so y = -3 after you divide both sides by 4. Use this y value to find the value of x
x+2y = -10
x + 2(-3) = -10
x - 6 = -10
x = -10+6
x = -4
The single solution is (x,y) = (-4,-3)
As a check, plug this solution into each equation to see if you get a true statement or not. Let's do so with the first equation
x+2y = -10
-4 + 2(-3) = -10
-4 - 6 = -10
-10 = -10 .... true
and then the second equation
-x+2y = -2
-(-4) + 2(-3) = -2
4 - 6 = -2
-2 = -2 .... true
both equations are true, so the solution is confirmed

The probability of rolling a sum of 7 when rolling two dice simultaneously is 0.167. You decide to test that probability by rolling the dice 12 times. What is the probability that exactly 2 of the rolls is a sum of 7?
Answer:
The probability that exactly 2 of the rolls is a sum of 7 will is 0.296
Step-by-step explanation:
The probability of rolling a sum of 7 when rolling two dice simultaneously is 0.167.
Let us assume that, A be the event that the sum is 7. So,
[tex]P(A)=0.167[/tex]
Binomial probability represents the probability that a binomial experiment results (i.e either success or failure or only two results) in exactly x successes.
[tex]b(x;\ n, p) =\ ^nC_x \cdot p^x \cdot (1-p)^{n - x}[/tex]
So the probability that exactly 2 of the rolls is a sum of 7 will be,
[tex]P(2) =\ ^{12}C_2 \cdot (0.167)^2 \cdot (1-0.167)^{12 - 2}[/tex]
[tex]=\ ^{12}C_2 \cdot (0.167)^2 \cdot (0.833)^{10}[/tex]
[tex]=66 \cdot (0.167)^2 \cdot (0.833)^{10}[/tex]

The equation of a parabola is given. y=1/2 x 2+6x+24 What is the equation of the directrix of the parabola? Enter your answer in the box. will report if u give some random answer just to get points
Answer: y = 5.5
Step-by-step explanation:
[tex]y=\dfrac{1}{2}x^2+6x+24[/tex]
Step 1: find the vertex
axis of symmetry: [tex]x = \dfrac{-b}{2a} = \dfrac{-6}{2(\frac{1}{2})} =\dfrac{-6}{1} = -6[/tex]
y-coordinate of vertex: [tex]y=\dfrac{1}{2}(-6)^2+6(-6)+24[/tex]
= 18 - 36 + 24
= 6
Vertex: (-6, 6)
Step 2: find p (the distance from the vertex to the focus): [tex]\dfrac{1}{4p} =a[/tex]
[tex]\dfrac{1}{4p} =\dfrac{1}{2}[/tex]
cross multiply to get: 2 = 4p
divide both sides by 4 to get: [tex]p =\dfrac{1}{2}[/tex]
Step 3: find the directrix
Since the parabola opens up, the focus will be above the vertex.
focus: (-6, 6 + [tex]\dfrac{1}{2}[/tex]) = (-6, 6.5)
and the directrix will be below the vertex.
directrix: y = 6 - [tex]\dfrac{1}{2}[/tex] ⇒ y = 5.5
The directrix also gets shiftd toward right. Then the equation of the directrix of the parabola will be y = 11/2.
What is the parabola?The equation of a parabola function is given as,
y² = 4ax
x² = 4ay
Where a is the coordinate of the focus.
The equation of a parabola is given.
y = (1/2) x² + 6x + 24
Simplify the equation, we have
2y = x² + 12x + 48
2y = x² + 12x + 36 + 12
2y = (x + 6)² + 12
Then the equation can be written as,
4(1/2)y = (x + 6)² + 12
Compare with standard equation, we have
a = (-1/2, 0)
The parabola is gets shifted toward right.
Then the directrix also gets shiftd toward right.
Then the equation the directrix will be
y = -1/2 + 6
y = 11/2

Kiran read for x minutes, and Andre read for 58 more than that. Write an equation that relates the number of minutes Kiran read with y, the number of minutes that Andre read. Use decimals in your equation.
Answer:
[tex]0.017y=0.017x+0.97[/tex]
Step-by-step explanation:
Let us assume that,
number of minutes read by Kiran is = x minutes.
number of minutes read by Andre is = y minutes.
Andre read for 58 minute more than that of Kiran.
Converting minute to hour we get,
[tex]x\text{ minutes}=\dfrac{x}{60}=0.017x\text{ hour}[/tex]
[tex]y\text{ minutes}=\dfrac{y}{60}=0.017y\text{ hour}[/tex]
[tex]58\text{ minutes}=\dfrac{58}{60}=0.97\text{ hour}[/tex]
So the relationship between x and y will be,
[tex]0.017y=0.017x+0.97[/tex]
To relate the number of minutes Kiran read with the number of minutes Andre read, we can use the equation y = x + 58, where x is the number of minutes Kiran read.
Explanation:To write an equation that relates the number of minutes Kiran read with y, the number of minutes that Andre read, we can use the information given. Let's say Kiran read for x minutes. According to the question, Andre read for 58 more than that, so we can represent Andre's reading time as x + 58. Therefore, the equation would be y = x + 58.

The student is asking about the probability of selecting a green marble followed by a striped marble when drawing from a bag that contains red, green, and striped marbles with replacement. To calculate this probability, we will use the basic principle that the probability of two independent events happening in sequence is the product of their individual probabilities.
First, we determine the probability of choosing a green marble, which we'll call P(G). Since the bag contains 7 green marbles out of a total of 25 (10 + 7 + 8), the probability P(G) is 7/25. Next, since the marble is replaced, the probability of choosing a striped marble, P(S), remains the same at 8/25. Therefore, the probability of choosing a green marble and then a striped marble is P(G and S) = P(G) x P(S) = (7/25) x (8/25).
To find the combined probability, simply multiply the two individual probabilities:
P(G and S) = (7/25) x (8/25) = 56/625.
The probability of drawing a green and then a striped marble is 56/625.
what is the mass of an object that has a density of 0.7 g/cm3 and a volume of 8cm3? (the density of an object has the equation d=m/v)
A.7.3g
B.5.6G
C.0.18G
D.11.4G
Answer:
B.5.6g
Step-by-step explanation: Density of object=mass/volume
Therefore, Mass=density of object X volume
=0.7 X 8
=5.6g
Answer:
Mass of an object is:
B. 5.6 g
Step-by-step explanation:
Mass of an object= Density × Volume
An object that has a density of 0.7 g/cm³
and a volume of 8 cm³
Mass= 0.7 g/cm³ × 8 cm³
= 5.6 g
Hence, Correct option is:
B. 5.6 g
Solve the equation for the given variable
2x - y = z ;x
Hello from MrBillDoesMath!
Answer:
x = (1/2) (z + y)
Discussion:
Solve 2x-y =z for x.
2x -y = z =>
2x -y + y = z + y => ( add "y" to both sides)
2x = z + y
x = (1/2) (z + y) ( divide both sides by 2)
