Answer:
No
Step-by-step explanation:
we have the number
[tex]7,027[/tex]
we know that
[tex]7,027=7*1,000+2*10+7*1[/tex]
so
The value of the first 7 is equal to
[tex]7*1,000=7,000[/tex]
The value of the second 7 is equal to
[tex]7*1=7[/tex]
therefore
[tex]7,000/7=1,000[/tex]
The value of the first 7 is one thousand times greater than the second 7
The answer is no
-27/50 write the fraction as a mixed number
Answer: It can not be a mixed number because if you divide -27 by 50 you get -0.54, so then if you turn -0.54 in fraction form it would be -27/50, so the fraction would stay the way it is. -27/50 is not an improper fraction. To be improper, the numerator must be greater than the denominator!

Shravan is ten years older than Gaurav’s age. Five years ago, one –seventh of shravan’s age was equal to one- fifth of Gaurav’s age. Find their present ages.
Answer:
Shravan's age is 40 years old
Gaurav’s age is 30 years old
Step-by-step explanation:
Let
x-----> Shravan's age
y-----> Gaurav’s age
we know that
x=y+10 -----> equation A
(1/7)(x-5)=(1/5)(y-5) ----> equation B
substitute equation A in equation B and solve for y
(1/7)(y+10-5)=(1/5)(y-5)
(1/7)(y+5)=(1/5)(y-5)
5(y+5)=7(y-5)
5y+25=7y-35
7y-5y=25+35
2y=60
y=30 years
Find the value of x
x=y+10 ----> x=30+10=40 years
therefore
Shravan's age is 40 years old
Gaurav’s age is 30 years old

ANSWER
a. 16
b. 1
c. 64
d. 64
EXPLANATION
We want to simplify the following exponential expressions
a.
[tex] {2}^{4} [/tex]
This implies that
[tex] {2}^{4} = 2 \times 2 \times 2 \times 2[/tex]
[tex] {2}^{4} = 16[/tex]
b. Any non-zero number exponent zero is 1.
This implies that,
[tex] {3}^{0} = 1[/tex]
c. The given exponentiial expression is,
[tex] {4}^{6} \times {4}^{ - 3} [/tex]
The bases are the same so we add the exponents.
[tex] {4}^{6} \times {4}^{ - 3} = {4}^{6 + - 3} [/tex]
This simplifies to,
[tex]{4}^{6} \times {4}^{ - 3} = {4}^{3} [/tex]
[tex]{4}^{6} \times {4}^{ - 3} = 4 \times 4 \times 4 = 64[/tex]
d. We want to simplify:
[tex] { ({2}^{3}) }^{2} [/tex]
This is the same as
[tex]{ ({2}^{3}) }{ ({2}^{3}) }[/tex]
We add the exponents now to get:
[tex]{2}^{3 + 3} = {2}^{6} = 64[/tex]

How do I solve -6 1/3 + 5 5/6
Answer:
13/6
Step-by-step explanation:
-6 1/3 + 5 5/6
1. You can reduce the first equation to 2
-6 1/3, becomes -2 x 1/1. This is because 3 goes into itself 1 time, and it goes into 6, -2 times. Your new equation: -2 + 5 5/6
2. Multiply the 5's in 5 5/6 by each other to get...
25/6
Your new equation: -2 + 25/6
3. Multiply 6 by -2 to get -12
4. Now add the numerators(remember -12 is basically, -12/1) together to get your answers
-12 + 25/6 = 13/6
Hello There!
If we add -6 1/3 and 5 5/6 together, we will get a sum of -1/2
STEP 1 First, I like to convert mixed numbers into improper fractions because they are easier to work with. So, I would change -6 1/3 to -19/3. Then, I would change 5 and 5/6 to 35/6.
STEP 2 Applying the fraction formula for addition. (-19x6) + (35x3) and then i would put this over 6x3

if one bucket + 5 jars equal one tub and three buckets plus two jars equal to tubs how many jars are there equal to one tub
Answer:
Simplify 4y + 7x = 2t and there you go that's your answer☺
Step-by-step explanation:
Bucket = y
Jars = x
Tubs = t
y + 5x = t
3y + 2x = t
Answer:
Number of jars in one tub is:
13
Step-by-step explanation:
Let b denote the buckets, j denotes the jars and t denotes the tubs
One bucket + 5 jars equal one tub
b+5j=t ----------------(1)
Three buckets plus two jars equal two tubs
3b+2j=2t ------------------(2)
equation (1)×3- equation (2)
3(b+5j)-(3b+2j)= 3t-2t
3b+15j-3b-2j= t
13j= t
Hence, Number of jars in one tub is:

graph and shade the following inequality -5x+2y<-10
Answer: The graph is attached.
Step-by-step explanation:
The equation of the line in Slope-intercept form is:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
You can solve for "y":
[tex]2y<5x-10\\\\y<\frac{5}{2}x-\frac{10}{2}\\\\y<\frac{5}{2}x-5[/tex]
You need to rewrite the expression:
[tex]y=\frac{5}{2}x-5[/tex]
You can identify that the slope of this line is:
[tex]m=\frac{5}{2}[/tex]
And the y-intercept is:
[tex]b=-5[/tex]
Substitute [tex]y=0[/tex] and solve for "x" to know the x-intercept:
[tex]0=\frac{5}{2}x-5\\\\5*2=5x\\\\x=2[/tex]
Now you know that the line passes through the points (0,-5) and (2,0).
Since the inequality is "<", you know that the line must be dashed and the shaded region must be below the line [tex]y=\frac{5}{2}x-5[/tex].
Knowing this, you can graph it (Observe the graph attached)

b. x greater or equal than 1.8
c. x less or equal than negative 1.8
d. x greater or equal than negative 1.8
Answer: Option b
b. x greater or equal than 1.8
Step-by-step explanation:
In this problem we have the following inequality:
[tex]2x\leq 3(x-0.6)[/tex]
To solve it we must group the x on one side and the constants on the other side
[tex]2x\leq 3(x-0.6)[/tex]
Apply distributive property on the right side of the inequality
[tex]2x\leq 3x-3*0.6[/tex]
[tex]2x\leq 3x-1.8[/tex]
Subtract 3x on both sides of the inequality
[tex]2x-3x\leq 3x-3x-1.8[/tex]
[tex]-x\leq-1.8[/tex]
Multiply by -1 both sides of the inequality
[tex]x\geq 1.8[/tex]

The length of the hypotenuse of a right triangle is 157 units. The length of one leg of the triangle is 132 units. Lara wrote the following step to find the length of the unknown leg: Length of the unknown leg = 1572 − 1322 = 24,649 − 17,424 = 7,225 units Which statement best explains whether Lara's step is correct or incorrect?
Answer:
24649-17424=7225 UNITS
Step-by-step explanation:
This step implies that Lara was using the Pythagoras theorem to find the missing length of the right triangle.
a²+b²=c², taking a and b to be the two lengths adjoined by the right angle and c the hypotenuse.
Laura's step represents the step above.
157²=24649
132²=17424
157²-132²=c²
24649-17424=7225
Write the equation of the line that passes through the point (6, -2) and is perpendicular to the line
y = 1/3x+8.
Answer:
y = - 3x + 16
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x + 8 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, so
y = - 3x + c ← is the partial equation of the perpendicular line
To find c substitute (6, - 2) into the partial equation
- 2 = - 18 + c ⇒ c = - 2 + 18 = 16
y = - 3x + 16 ← equation of perpendicular line

Identify each expression and value that represents the area under the curve y=x^2+4 on the interval [-3,2]
This result represents the total area under the curve y = x^2 + 4 between x = -3 and x = 2.
The area under the curve y = x^2 + 4 on the interval [-3,2] can be found using definite integration. The definite integral of a function gives us the net area between the function and the x-axis across the specified interval. To compute the area, we set up the integral from -3 to 2 of the function x^2 + 4.
To solve this, we integrate the function with respect to x:
Integrate the function x^2 to get (1/3)x^3.Integrate the constant 4 to get 4x.Combine the results to form the antiderivative, which is (1/3)x^3 + 4x.Evaluate the antiderivative from -3 to 2. This gives us:[(1/3)(2)^3 + 4(2)] - [(1/3)(-3)^3 + 4(-3)]Calculate each part to obtain:[(1/3)(8) + 8] - [-(1/3)(27) - 12]Simplify to find: (8/3 + 8) - (-9 - 12)Add up to get the total area: (8/3 + 8 + 9 + 12)Which simplifies to: (8/3 + 29)Final result: 35/3 or 11.67 square unitsThis result represents the total area under the curve y = x^2 + 4 between x = -3 and x = 2.
which of the following is the conjugate of a complex number with 2 as the real part and -8i as the imaginary part
The conjugate of the complex number 2 - 8i is 2 + 8i, found by changing the sign of the imaginary part from negative to positive.
The conjugate of a complex number is found by changing the sign of the imaginary part.
For a complex number with a real part of 2 and an imaginary part of -8i, the complex number is represented as 2 - 8i. To find its conjugate, we change the sign of the imaginary part, resulting in 2 + 8i.
The general form of a complex number is a + bi, where a is the real part and bi is the imaginary part.
The conjugate is then written as a - bi. Therefore, if we have the complex number z = 2 - 8i, the conjugate, denoted as [tex]\( \overline{z} \)[/tex], is 2 + 8i.
