Answer: Check out the diagram below.
Explanation:
Use a calculator to find that:
[tex]A = \sqrt{18} \approx 4.24\\\\B = \sqrt{73} \approx 8.54\\\\C = \sqrt{30} \approx 5.48\\\\D = \sqrt{52} \approx 7.21\\\\E = \sqrt{7} \approx 2.65\\\\[/tex]
You'll then plot those decimal approximate values on the number lines given.
For example, 4.24 will go somewhere between 4 and 5. It's closer to 4 than it is to 5. The other values are handled the same way. The placement of the points doesn't have to be perfect.
Check out the diagram below. I made one single number line and plotted all the values on it. However, you'll have 5 separate number lines (one value per number line).
Which equation does
NOT represent a direct variation?
A) y= 5x
C) y= 15x
B) y -5x
D) y= 5x+1
You are remodeling your kitchen. You have contacted 2 tiling companies who gladly told you how long it took their workers to tile a floor of a similar size. Jim completed 1/2 the floor in 12 hours, Pete completed the other 1/2 in 10 hours. If Pete can lay 25 more tiles per hour than Jim, what equation would you use to find the rate that Jim can lay tiles? Let x represent Jim's rate.
A. 10x = 12 (x -25)
B. 12x = 10 (x + 25)
C. 10x = 12 (x + 25)
D. 12x = 10 (x - 25)
Hence, Jim can lay 125 tiles and Pete can lay 25 more so 125+25=150 tiles.

u can use a calculator
Step-by-step explanation:
use BODMAS rule
#13. 6x — Зу = 8
#14. 7x = 5y + 2
#15. — бу + 4х = 8
#16. T+2 = 2x + 3
I need slope and y-intercept and rearrange each equation into slope-intercept
#13
6x — Зу = 83y = 6x - 8y = 6/3x - 8/3y = 2x - 8/3The slope = 2The y- intercept = - 8/3#14
7x = 5y + 25y = 7x - 2y = 7/5x - 2/5y = 1.4x - 0.4The slope = 1.4The y- intercept = - 0.4#15
- 6у + 4х = 86y = 4x - 8y = 4/6x - 8/6y = 2/3x - 4/3The slope = 2/3The y- intercept = -4/3#16 is not clear

Answer:
The graph showing the temperature change over time is missing.
Step-by-step explanation: The slope of the line in the graph is the rate of temperature change per minute.
1. Calculate the slope between for each of the 3 ranges listed. Slope is rise/run: Take two points at the upper and lower boundaries of each range. You should have three sets of points:
e.g., (0,100) and (340, 175); (345, 176) and (360, 180); finally (360,185) and (380, 200). I made these up, since there is no graph. but the x values, the time in minutes, correspond to the ranges requested.
If the slopes are diferent, then explain that the rate of temperature rise is different for each segment.
3. Time is 360 + 60 = 420, temperature is 80: (420,80)
Find the equation of the line passing through the points (2, -1) and (-6, -5)

solve for y
6x - 3y = 15
hint - subtract 6x, divide by -3, simplify
Answer:
y=2x-5
Step-by-step explanation:
1) Factor out the common term 3
3(2x-y)=15
2)Divide both sides by 3
2x-y=15/3
3) Simplify 15/3 to 5
2x-y=5
4) Subtract 2x from both sides
-y=5-2x
5) Multiply both sides by -1
y=-5+2x
6) regroup terms
y=2x-5

Mrs. Glaser was extremly hungry one day and decided to eat some delicious tacos. She bought 6 tacos for 10$ and this rate houch would 4 tacos cost?
Answer: First you want to divide $10 from 6 tacos. You should get a number like 1.6666 continuing, the. You want to multiply the 4 tacos times the answer you got from 10/6 so your problem would look like 1.66667 x 4
You should get 6.6667 or you can sum it up with 6.67 or $6.70

D) 46°
Answer:
B
Step-by-step explanation:
i estimated this answer
Answer:
= 50, C
Step-by-step explanation:
? = 50
This is because the 50 shown is vertically opposite to the unknown angle, which they are equal
(Vertically opposite angles can be formed between two opposing lines)
1/11 as a decimal
59/9 as a reduced mixed number
Answer:
1. .09 repeating 2. 6 5/9
Step-by-step explanation:
to turn a fraction into a decimal you divide the top number of a fraction by the bottom one. To convert an improper fraction to a mixed fraction, divide the numerator by the denominator, write down the quotient as the whole number and the remainder as the numerator on top of the same denominator

Please help!!!! i am despite, i will mark brainlyest
Answer:
x=12
10x = 120
5x = 60
Step-by-step explanation:
paralellograms will become 360 degrees
so 2(5x) +2(10x)= 360
Simplify:
10x + 20x = 360
= 30x
divide both sides by 30 and isolate
30x = 360
30 30
x=12
multiply 12 by 10x and 5x
10x = 120
5x = 60
i was absent the day they taught this and my teacher refuses to teach me
Step-by-step explanation:
it's something in algebra i don't remember but basically the top number (12) has the x on the bottom which is multiplication and the bottom number (8) has addition so those tell u how ur supposed to get those numbers
so basically u need to find two numbers that add up to 8 and multiply to 12 so the factors are 6 and 2 because 6 • 2 is 12 and 6 + 2 = 8. hope this helps
Answer:
6 and 2
Step-by-step explanation:
6 x 2= 12
6 + 2= 8

The charge in dollars for cab rides in one city is modeled by f(c)=4+2.5m, when m is the number of miles traveled.
What is the charge for a 3-mile ride?
f(c) = 4 + 2.5 (3) ; (3 miles)
4 + 7.5
11.5
Charge: $11.5Which equation is graphed?
Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 2 ) and (x₂, y₂ ) = (2, - 4) ← 2 points on the line
m = [tex]\frac{-4-2}{2-(-2)}[/tex] = [tex]\frac{-6}{2+2}[/tex] = - [tex]\frac{6}{4}[/tex] = - [tex]\frac{3}{2}[/tex]
and using (a, b ) = (2, - 4 ) , then
y - (- 4) = - [tex]\frac{3}{2}[/tex](x - 2) , that is
y + 4 = - [tex]\frac{3}{2}[/tex] (x - 2) → C
Each face of a pyramid is an isosceles triangle with a 72 degree vertex angle. What are the measures of the base angles?
Answer:
52° and 52°
Step-by-step explanation:
An isosceles triangle has two base angles that are congruent. So let x be the measure of the base angle so that by Triangle Angle-Sum Theorem, we can write: X+X+76=180 and next would be 2X+76=180 and then it would be 2X=104 and finally it would be X=52. So there for the measures of the base angles are 52° and 52°. There hoped it helped!!!!
