Answer:
3x + 8
Step-by-step explanation:
x + 5 + 2x + 3
You have to add like terms. You can't add x and 5 or 2x and 3.
x + 2x is like 2x + 2x, so 3x
5 + 3 is 8, so 3x + 8 is the answer.
A latter leans agains the side of a house.The top of the ladder is 24ft from the ground. The bottom of the lAdder is 7ft from the side of the house. Find the length of the ladder.
Answer:
25 feet
Step-by-step explanation:
You can superimpose a triangle in this situation. The height from the ground to the top of the ladder along the wall is one leg of the triangle, the distance the ladder is from the wall is the other leg, and the length of the ladder is the hypotenuse.
Use Pythagorean theorem to solve, which is a² + b² = c² where a, and b are the legs, and c is the hypotenuse...
We have
7² + 24² = c²
49 + 576 = c²
625 = c²
25 = c
*Tecnhically the answer is ±25, but it's a length, so we disregard the negative answer.

find the area of this figure
Answer:
79.25 square inches
Step-by-step explanation:
To find the area of the figure, split it into two shapes - a rectangle and a semi-circle.
The area of a rectangle is A = b*h. Substitute b = 10 and h = 4.
A = 4*10 = 40.
The area of a semi-circle is A =1/2 πr². Substitute r = 5 since the diameter is 10.
A =1/2 π5² = 12.5π = 39.25.
Add the two areas together.
39.25 + 40 = 79.25

So
140/300 = 0.4666
Converting this into percentage again
We will multiply the decimal by 100
0.4666 x 100 = 46.66 %
Solve the inequality 3k > 5k+12
Alright, let's solve this problem! :)
First we need to subtract 5k from both sides.
3k−5k>12
Then we simplify 3k - 5k to -2k.
-2k > 12
Now we divide both sides by -2.
k < -12/2
Now we simplify 12/2 to 6.
k < -6

Answer:
No 1 inch cubes will fit
28 one-half inch cubes will fit
Step-by-step explanation:
No cubes with a side length of 1 inch will fit because one dimension of the prism is only 1/2 inches, so we can't fit a 1 inch cube in anywhere.
Since one dimension is 1/2 inch, we can line up 1/2 inch cubes along the other 2 dimensions. Let's say that the 1/2 inch dimension is the base, the 2 inch dimension is the height, and the 7/2 inch dimension is the length.
We can stack the cubes 4 high, (2 inches of height with 1/2 inch being the cube height, there are 4 halves in 2).
We can place 7 cubes along the length (7/2 inches = 3.5 inches. There are 7 halves in 3.5).
So we can have 4(7) = 28 one half inch cubes can fit in to the prism

Which of the following rules represents the function shown in the table?
This is F(n) = 3n
The X is an interger which is holding a value
The relationship between Y and X is 3n as we multiply X by 3 to get the value of Y and is proven yet so.
The rule which represent the function as shown in the table is:
[tex]f(n)=3n[/tex]
Step-by-step explanation:We are given a table as follows:
x 2 -1 0
y 6 -3 0
Now we are asked to find the function which represent these table of values.
a)
[tex]f(n)=n+3[/tex]
Here x is represented by n and y by f(n)
when n=2 we must have f(n)=6
Hence, we put n=2 in the given expression and check,
[tex]f(2)=2+3=5\neq 6[/tex]
Hence, this is not a correct function.
b)
[tex]f(n)=\dfrac{1}{3}n[/tex]
Again we check for n=2
We have:
[tex]f(2)=\dfrac{1}{3}\times 2=\dfrac{2}{3}\neq 6[/tex]
Hence, it is not a correct expression.
So we are left with option: c)
c)
[tex]f(n)=3n[/tex]
By putting the value of n=2,-1 and 0
we see that the expression matches the table of values.
( since,
when n=2 we have:
[tex]f(2)=3\times 2=6[/tex]
when n= -1 we have:
[tex]f(-1)=3\times -1=-3[/tex]
and when n=0 we have:
[tex]f(0)=3\times 0=0[/tex] )
Hence, this is a correct expression.

Many has 40 ounce of butter that he is cutting into 1.25 ounces . How many slices will he have?
He would have 32 slices of butter.
The student will have 32 slices of butter if they cut 40 ounces into 1.25-ounce pieces by dividing the total amount by the size of each slice.
The student wants to know how many slices of butter they can get from 40 ounces if they are cutting it into 1.25 ounces each. To find out, they need to divide the total amount of butter by the size of each piece.
First, take the total amount of butter, which is 40 ounces.
Divide 40 ounces by the size of each slice, which is 1.25 ounces.
Calculate the division: 40 / 1.25 = 32 slices.
Therefore, the student will have 32 slices of butter if they cut 40 ounces into 1.25-ounce pieces.

While taking inventory at her bakery, Ruby noticed that she had 5⁄6 pound of cinnamon yesterday, but now had only 2⁄3 pound. How much more cinnamon did Ruby have yesterday?
Answer:
1/6 of a pound
Step-by-step explanation:
Multiply both the numerator and denominator for a common denominator.
2/3 * 2/2 = 4/6.
Then subtract to find out how much more she had yesterday.
5/6-4/6=1/6.
1/6 pound
Match the denominator
2/3 = 4/6
Subtract
5/6 - 4/6 = 1/6

The correct answer is A.
Hope this helps.
Answer:
The answer is A.
Step-by-step explanation:
This is because it wants you to represent the answer in Slope-Intercept Form. Which is y = mx + b. B is the y intercept, which is where it starts. On a graph, the y-intercept starts at ZERO. The 3 is at the zero, so you know what the first number is. Then, you need to see the fluctuation (change) in the value of each number in the y as you increase in x. As the x increases by one, you can see that the y decreases by two. So now you know, the ROC or Rate of Change is two, which is your slope. Slope is m. So if m is two, that makes 2x.

Answer:
f(x)⁻¹ = 3x/(2 - x)
Step-by-step explanation:
Find the inverse of f(x) = 2x/(x+3)
The first step is to let f(x) = y
y = 2x/(x+3)
Then make x the subject of the formula
y = 2x/(x+3)
y(x + 3) = 2x
yx + 3y = 2x
yx - 2x = -3y
x(y - 2) = -3y
x = -3y/(y - 2)
∴ f(x)⁻¹ = -3x/(x - 2)
Dividing both numerator and denominator by -1;
f(x)⁻¹ = 3x/(2 - x)

What is the exact volume of the figure?
Answer: 890.12 cm^3
Step-by-step explanation:
The formula for the volume of a cylinder is
[tex]V=\pi *r^2*h[/tex]
V=628.3185307 cm^3
or simply
V=628.32 cm^3
Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.
Next, the formula for the volume of a sphere is
[tex]V=\frac{4}{3} \pi *r^3[/tex]
so the volume of a hemisphere is half of that or:
[tex]V=\frac{2}{3} *\pi *r^3[/tex]
V= 261.7993878 cm^3
or simply
V=261.80 cm^3
Finally, you add both of the volumes together to get
V= 890.1179185 cm^3
or simply
V=890.12 cm^3
Franco wants to have $750,000 when he retires in a year. If he currently has $700,000 to put in a 1-year CD, which of these APRs and compounding periods will allow him to reach his goal?
Answer:
Francesco can achieve this amount by investing at an APR of 7.14% compounded annually , or 7% compounded every six months or 6.95% compounded quarterly
Step-by-step explanation:
This question can be solved using the concept of compounded interest
The formula for amount obtained when a principal of p was invested at a rate r compounding n times a year is:
[tex]Amt = p(1+\frac{r}{100n})^n[/tex]
Here p = 70000, amt = 75000,
So when compounded annually, n=1
[tex]Amt =p(1+\frac{r}{100n})^n\\75000=70000(1+\frac{r}{100})^1\\\frac{15}{14}=1+\frac{r}{100}\\\frac{1}{14}=\frac{r}{100}\\r = \frac{100}{14}=7.14[/tex]
For compounding every 6 months n=2
[tex]Amt =p(1+\frac{r}{100n})^n75000=70000(1+\frac{r}{200})^2\\\frac{15}{14}=(1+\frac{r}{200})^2\\\sqrt{\frac{15}{14}}=1+\frac{r}{200}\\r = 200*(\sqrt{\frac{15}{14}}-1)=7.01[/tex]
For compounding quarterly n=4
[tex]Amt =p(1+\frac{r}{100n})^n\\75000=70000(1+\frac{r}{400})^4\\\frac{15}{14}=(1+\frac{r}{400})^4\\(\frac{15}{14})^\frac{1}{4}=1+\frac{r}{400}\\r = 6.95[/tex]

Find the equation of the line. Use exact numbers.
Y= ___x + ___
Answer:
y = 3x + 3
Step-by-step explanation:
The graph passes through the points (-1, 0) and (0, 3).
Slope = m = Δy/Δx = (y₂ - ₁)/(x₂ - x₁) = (3 - 0)/(0 - (-1)) = 3/1 = 3.
The y-intercept (b) is at y = 3.
The equation for a straight line is
y = mx + b
Thus, the equation for your line is
y = 3x + 3
