Answer:
The equation of the line is y = (5/2)x + 5.
Step-by-step explanation:
When both line are parallel, they share the same gradient value so the equation will be y = (5/2)x + b. Next, you have to find the value of b, by substituting the coordinates into the equation :
y = (5/2)x + b
let x = -2, y = 0,
0 = (5/2)(-2) + b
0 = -5 + b
b = 5
Answer:
y=5/2x+5
Step-by-step explanation:
Since both lines are parallel they have the same slope. From y=5/2x+1, the slope is 5/2
The equation of the line passing through (-2,0) using slope intercept form is
y-y1=m(x-x1)
y-0=5/2(x--2)
y=5/2(x+2)
y=5/2x+5

Find the surface area of the prism
Answers
=========================================================
Explanation:
The front triangular face is a triangle with base 8 and height 6. Its area is
A = 0.5*base*height
A = 0.5*8*6
A = 24 square feet
The back triangular face is also 24 square feet since these are the base faces of the prism. The base faces are always congruent. It might help to imagine this figure is turned on its side.
The slanted lateral face is a rectangle of length 10 ft and width 5 ft, so its area is L*W = 10*5 = 50 square feet
The rectangular face on the left is 6 ft by 5 ft giving an area of 6*5 = 30 square feet.
Lastly, the bottom rectangular face is 8 ft by 5 ft giving an area 8*5 = 40 square feet
Overall, the total surface area is: 24+24+50+30+40 = 168 square feet
We just add up all the individual areas of each face to get the total surface area.

3/7 of the students in a school are girls. If there are 64 boys find how many girls there are
Answers
Answer:
About 28
Step-by-step explanation:
Answer:90
Step-by-step explanation:Hi.
Here is your answer---
Let the number of Students in a school be x.
Thus,Number of Girls = 3/7 of the total Students
= 3/7 of x
= 3x/7
We know,
Number of Boys + Number of Girls = Total Students.
64 + 3x/7 = x
64 = x - 3x/7
64 = (7x - 3x) /7 [Taking L.C.M.]
64 × 7 = 4x
x = 60 × 7
x = 420
Total number of Students in a school is 420.
Thus, Number of Girls = 3/7 × x
= 3/7 × 420
= 90
Thus, the number of Girls in a school is 90.

Brainliest pleasethe ratio of the length of a rectangle to its width 3:2. Give 3 possible dimensions of the rectangle in cm
Answers
Answer:
1.) 3:2 → length = 3cm ; width = 2cm
2.) 6:4 → length = 6cm ; width = 4cm
3.) 9:6 → length = 9cm ; width = 6cm
Step-by-step explanation:
The ratio 3:2 is length:width. This means that if you were to simplify the values by a common factor, the result would always be [tex]\frac{3}{2} = \frac{length}{width}[/tex].
To find three dimensions, pick any random three numbers and multiply one by one to both numerator and denominator:
[tex]1,2,3\\\\\frac{3}{2}(\frac{1}{1} )= \frac{3}{2} \\\\\frac{3}{2} (\frac{2}{2} )=\frac{6}{4}\\\\\frac{3}{2} (\frac{3}{3} )=\frac{9}{6}[/tex]
Convert the given ratios to length and width:
1.) 3:2 → length = 3cm ; width = 2cm
2.) 6:4 → length = 6cm ; width = 4cm
3.) 9:6 → length = 9cm ; width = 6cm
If you were to simplify each, the result would be 3:2.

What are the greatest common factor of 9a^b and 30ab^3?
Answers
Answer: 3ab IF a^b does NOT mean a to the power of b!
I believe you mean 9a²b and 30ab³
If you really mean 9aᵇ and 30ab³, then the GCF is 3a.
Step-by-step explanation:
the factors of 9 are 3*3 The factors of 30 are 2*3*5.
The only common factor of 9 and 30 is 3
a is a common factor of a and a²
b is a common factor of b and b³
Prasitha has two buildings A and B. A is 10 feet shorter than the twice the height of B. The distance between the buildings is 120 feet and the height of B is 60 feet. Find the distance between their tops.
Answers
Answer:
The distance between their tops is 130 feet
Step-by-step explanation:
The given parameters are;
The height of A, [tex]h_A[/tex] = 2 × The height of B - 10
The distance between the two buildings, d = 120 feet
The height of B, [tex]h_B[/tex] = 60 feet
Therefore, we have;
The height of A, [tex]h_A[/tex] = 2 × The height of B - 10 = 2 × 60 - 10 = 110 feet
The height of A, [tex]h_A[/tex] = 110 feet
By Pythagoras theorem, the distance between their tops = √(([tex]h_A[/tex] - [tex]h_B[/tex])² + d²)
Substituting the values gives;
The distance between their tops = √((110 - 60)² + 120²) = 130
The distance between their tops = 130 feet.

Daren draws a scale model of the Statue of Liberty that is 15 inches tall. If the Statue of Liberty is 305 feet tall, what is the scale of the model?
Answers
Answer:
The scale of the model is 1 : 244.
Step-by-step explanation:
15 inches = 1.25 feet. (1 inch = 0.0833333 feet)

Compute the variances in dollar amount and in percentage. (Round to the nearest whole percent.) Indicate whether the variance is favorable (F) or unfavorable (U). Budgeted Amount - Expense $255.00 Actual Amount $225.00
Answers
Answer:
Variance is the difference between a Budgeted Amount and the Actual Amount. In terms of expenses, if the Budgeted amount is more than the Actual amount, the variance is Favorable because less was spent than was supposed to be spent.
The reverse is true.
Variance = Budgeted Amount - Actual amount
= 255 - 225
= $30
Percentage = Variance / Budgeted amount
= 30/255
= 11.76%
The variance is FAVORABLE because the actual amount was less than the budgeted amount.

1. Which of the following lines is parallel to the line y = -3/2x +1 and contains the point (4,2)?
Answers
Answer:
The answer should be y = -[tex]\frac{3}{2}[/tex][tex]x[/tex] + 8, but its not one of the answers, so check the question again.
Step-by-step explanation:
If the second line is parallel, then the gradient will be the same:
y = -[tex]\frac{3}{2}[/tex][tex]x[/tex] + c
Find what c is (y-intercept) by inputting the given point into the equation (4,2):
2 = (-[tex]\frac{3}{2}[/tex] x 4) + c
2 = -6 + c
c = 8
