If a/b= 8 and ac -5 = 11, then bc =?
Answer:
bc = 2
Step-by-step explanation:
From [tex]a/b = 8[/tex]
[tex]a=8b[/tex] (times b on both sides)
We can then substitute [tex]a[/tex] for [tex]8b[/tex]:
[tex]ac-5=11[/tex] (given equation)
[tex]8bc-5=11[/tex]
[tex]8bc=16[/tex]
[tex]bc=2[/tex]

what does congruent mean in geomatry?
Answer:
Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal. Comment on David Severin's post “Congruent means same shape and same size.

What is HB? Triangle Mid-segment Theorem
Answer:
HB = 13
Step-by-step explanation:
In triangle GHJ, points A, B, C are mid points of the sides GH, HJ, GJ respectively.
Therefore by Mid-segment Theorem.
[tex]AC = \frac{1}{2} HJ \\ \\ 3y - 5 = \frac{1}{2} (4y + 2) \\ \\ 3y - 5 = \frac{1}{2} \times 2 (2y + 1) \\ \\ 3y - 5 = 2y + 1\\ \\ 3y - 2y = 5 + 1 \\ \\ y = 6 \\ \\ HJ = 4y + 2 \\ \\ HJ = 4 \times 6 + 2 \\ \\ HJ = 24 + 2 \\ \\ HJ = 26 \\ \\ HB= \frac{1}{2} HJ \\ \\ HB= \frac{1}{2} \times 26 \\ \\ \huge \red{ \boxed{ HB= 13}}[/tex]

7. The graph of the linear function is shown on the coordinate grid below.
Answer: C . The slope is -4/3 and the y-intercept is 4.
Step-by-step explanation:
Using the two given points, we will use them to evaluate the slope and the y intercept.
(-1.5,6)
( 4.5,-2)
To find the slope we will find the difference in the y coordinates of the points and divide it by the difference in the x coordinates of the point.
6-(-2) = 8
-1.5 - 4.5 = -6
Slope : 8/-6= -4/3.
Since the slope is -4/3, we will use the formula y= mx + b to find the y intercept. In the formula y= mx + b, the slope is m and b is the y intercept.
Use one of the given points, and input its x and y values into the formula including the slope to solve for b(the y-intercept).
We will use the point, ( -1.5,6)
6 = -4/3(-1.5) + b
6 = 2 + b
-2 -2
b = 4.
b is indeed equal to 4 because it even indicates on the graph that the y intercept is 4 which is where x is equal to 0.

Answer:
y=x-3
Step-by-step explanation:
The slope is just x, and the y intercept will be one over from (1,-2) which is (0,-3), so -3 is the starting point.

Answer:
x=12
Step-by-step explanation:
(2x-4)/5=4
We move all terms to the left:
(2x-4)/5-(4)=0
We multiply all the terms by the denominator
(2x-4)-4*5=0
We add all the numbers together, and all the variables
(2x-4)-20=0
We get rid of parentheses
2x-4-20=0
We add all the numbers together, and all the variables
2x-24=0
We move all terms containing x to the left, all other terms to the right
2x=24
x=24/2
x=12
Answer:
x = 12
Step-by-step explanation:
Given
[tex]\frac{2x-4}{5}[/tex] = 4 ( multiply both sides by 5 to clear the fraction )
2x - 4 = 20 ( add 4 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
A baseball is hit from an initial height of 3 feet and reaches a maximum height of 403 feet. Which function could be used to model this situation, where h(t) is the height, in feet, after t seconds?
A. h(t) = -16(t - 403)^2 + 3
B. h(t) = -16(t - 5)^2 + 3
C. h(t) = -16(t - 3)^2 + 403
D. h(t) = -16(t - 5)^2 + 403
Answer:
I believe its A
Step-by-step explanation:
D. h(t) = -16(t - 5)² + 403 could be used to model this situation.
What are the given informations ?A baseball is hit from an initial height of 3 feet.
The baseball reaches a maximum height of 403 feet.
Here, h(t) indicates the height in feet after t seconds.
Which function is correct ?At the start, t = 0 & Initial height = 3 feet ,i.e. h(0) = 3
We have to verify options by putting t = 0
A. h(t) = -16(t - 403)² + 3
So, h(0) = -16(0-403)² + 3 = -16(-403)² +3 = -2598544+3 = -2598541
B. h(t) = -16(t - 5)² + 3
So, h(0) = -16(0-5)² + 3 = -16(-5)² + 3 = -400+3 = -397
C. h(t) = -16(t - 3)² + 403
So, h(0) = -16(0-3)² + 403 = -16(-3)² + 403 = -144 + 403 = -259
D. h(t) = -16(t - 5)² + 403
So, h(0) = -16(0-5)² + 403 = -16(-5)² + 403 = -400 + 403 = 3
Hence, in this function h(0) = 3 verified.
Therefore h(t) = -16(t - 5)² + 403 is the required function.

Ms Tyler has a rectangular patio that she would like to decorate with string lights as shown in the diagram. If she plans to string the lights around the perimeter and across both diagonals how many feet of lights will she need? (READ CAREFULLY)
A: 47 feet
B: 60 feet
C: 80 feet
D: 13 feet
Answer:
the answer is b
Step-by-step explanation:
the answer would be b because you add 12+12 then 5+5 and if you add those together it would be 34 then you would add the diagonal lines together which would be 20 so then you would add 34 plus 26 and then you would get 60 which is b

the length of a rectangle is 5 more than twice the width. if the perimeter of the rectangle is 76 meters, find the dimensions of the rectangle and choose the equation that represents the perimeter:
1. 76=2w+5
2. 76=2w+2(2w+5)
3. 76=w+2w+5
4. 76=2w+(2w+5)
Answer:
Dimensions: 11 meters by 27 meters
2. [tex]76=2w+2(2w+5)[/tex]
Step-by-step explanation:
Finding Dimensions:
The perimeter of a rectangle can be written as [tex]2l+2w[/tex] where [tex]l[/tex] is the length and [tex]w[/tex] is the width. It is given that the length is 5 more than twice the length of width and the perimeter of the rectangle is 76 meters.
With this information we can write:
Length = [tex]2w+5[/tex]
[tex]2(2w+5)+2w = 76[/tex] (perimeter of the rectangle)
[tex]4w+10+2w=76[/tex]
[tex]6w=66[/tex]
[tex]w=11[/tex]
Length = [tex]2(11)+5[/tex]
Length = [tex]27[/tex]
∴ The dimensions of the rectangle is 11 meters by 27 meters.
Perimeter
Since the length can be written as [tex]2w+5[/tex], the equation that represents the perimeter of the rectangle is [tex]76=2w+2(2w+5)[/tex]
