Answer:
117 units
Step-by-step explanation:
if you use the ratio of the two longest sides then you can find all side lengths
[tex]\frac{52}{20}[/tex] = [tex]\frac{x}{10}[/tex]; x = half of 52, or 26
[tex]\frac{52}{20}[/tex] = [tex]\frac{x}{15}[/tex]; 20x = 52 · 15
20x = 780
x = 39
add to get perimeter: 52 + 26 + 39 = 117 units
Perimeter of the larger triangle is 117 units
Given
Two triangles are similar. The smaller triangle has side lengths 10, 20, and 15 units.
When the triangles are similar then the sides are in proportion
the longest side of the smaller triangle is 20 units
The larger triangle's longest side is 52 units.
Lets find out the unknown sides of largest triangle
Let x and y be the unknown sides . Make a proportion and solve for x and y
[tex]\frac{52}{20}=\frac{x}{10} \\x=\frac{52}{20} \codt 10\\x=26\\\\\\\frac{52}{20}=\frac{y}{15}\\y=\frac{52}{20} \codt 15\\y=39[/tex]
The unknown sides of largest triangle is 26 and 39 units
To find out the perimeter add all the sides of largest triangle
Perimeter =[tex]26+39+52=117[/tex]
Perimeter of the larger triangle is 117 units

The graph shows the activity in a savings account.
a. What was the amount of the initial deposit that started this savings account (don't use commas)?$
b. Find the slope.
c. Find the y-intercept.
d. Write an equation in slope-interce
form for the activity in this savings account.
Answer:
$1000 ; 500 ; 1000 ; y = 500x + 1000
Step-by-step explanation:
From the graph, the initial deposit which started the savings account is $1000 ; this is the value on the y - intercept, the value in the account at time or period = 0.
The slope :
x1 = 0 ; y1 = 1000
x2 = 6 ; y2 = 4000
Slope = Rise / Run
Rise = y2 - y1 = 4000 - 1000 = 3000
Run = x2 - x1 = 6 - 0 = 6
Hence,
Slope = 3000 / 6
Slope = 500
y - intercept = 1000 (from. Graph)
Equation in slope intercept form:
General form : y = mx + c
m = slope ; c = intercept
Equation is written as ;
y = 500x + 1000

Find the volume of each figure. Round your answers to the nearest hundredth, if necessary. Leave your answers in terms of pi for
answers that contain pi.
Answer:
D. 125π km³
Step-by-step explanation:
Volume of a cylinder = πr²h
Where,
radius, r = 5 km
Height, h= 5 km
Volume of a cylinder = πr²h
= π × (5 km)² × 5 km
= π × 25 km² × 5 km
= 125π km³

(f · g)(x) = –8x2 – 4x
C.
(f · g)(x) = –6x – 2
D.
(f · g)(x) = –16x2 – 4x
Step-by-step explanation:
Given
f(x) = - 4x - 2
g(x) = 2x

Answer:
Please check explanations for answer
Step-by-step explanation:
Here, we want to show that the left hand side equals the right hand side
We can express the left hand side as:
sin A/ cos A * sec A/cosec A
kindly recall that;
sin A/cos A = tan A
Also;
sec A = 1/ cos A
cosec A = 1/ sin A
Thus, we have that ;
tan A * 1/cos A / 1 / sin A
= tan A * sin A/cos A
This is;
tan A * tan A = tan^2 A

The number line from minus four to four by increment of one and each tick mark is labeled. In this number line point minus four is also labeled as G, minus three is labeled as H, minus two is labeled as I, minus one is labeled as J, zero is labeled as K, one is labeled as L, two is labeled as M, three is labeled as N, and four is labeled as O.
Answer:
HJ + JM = 5
Step-by-step explanation:
The number line is majorly used to show the positions of directed numbers. For the given question, the number line has the required points as shown in the attachment to this answer.
From the number line,
HJ = -1 - (-3)
= -1 + 3
= 2
HJ = -2
JM = 2 - (-1)
= 2 + 1
= 3
Thus,
HJ + JM = 2 + 3
= 5
HJ + JM = 5
Solve the system of linear equations by elimination.
3x−30=y
7y−6=3x
please explain
Answer: y = 6; x = 12
Step-by-step explanation:
3x - 30 = y
Change this into an equation where x and y are in the same side.
3x - 30 = y
Subtract y from both sides
3x - y - 30 = 0
Add 30 to both sides
3x - y = 30
7y - 6 = 3x
Do the same thing I did to the first equation
7y - 6 = 3x
Subtract 3x from both sides
-3x + 7y - 6 = 0
Add 6 to both sides
-3x + 7y = 6
We can now use the system of elimination to find x and y.
3x - y = 30
-3x + 7y = 6
After adding both equations, you get:
6y = 36
Divide 6 from both sides
y = 6
Since we now know y, we can solve for x.
3x - 30 = y
Substitute y for 6
3x - 30 = 6
Add 30 to both sides
3x = 36
Divide both sides by 3
x = 12
Hope this helped!
Answer:
[tex]x = 12.y = 6[/tex]
Step-by-step explanation:
Restructuring
[3x - 30 = y
-3x - 6 =7y
[tex] \frac{ - 36}{ - 6} = \frac{ - 6y}{6} [/tex]
y=6
Sub 6 in equ II

As table shows a proportional relationship between x and y then constant of proportionality are 20, 40, 0.2 and 20 respectively
In the first table, the constant of proportionality is 20 because each value of y is obtained by multiplying the corresponding value of x by 20.
In the second table, the constant of proportionality is 40 because each value of y is obtained by multiplying the corresponding value of x by 40.
In the third table, the constant of proportionality is 0.2 because each value of y is obtained by multiplying the corresponding value of x by 0.2.

A cooler contains bottles of orange juice,apple juice and grapefruit juice in the ratio of 3:4:3. There are 960 bottles of orange juice in the cooler Calculate the number of bottles of apple juice that are in the cooler
Answer:
1280
Step-by-step explanation:
The first 3 part of the ratio corresponds to 960 bottles of orange juice
Dividing 960 by 3 gives the value of one part of the ratio.
960 ÷ 3 = 320 ← value of 1 part of the ratio, then
apple juice = 4 × 320 = 1280 bottles
assume that the radius of a cylinder is the same as its height. What would happen to the volume of this cylinder if the radius were doubled and its height was half
9514 1404 393
Answer:

Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
Then the volume of the modified cylinder is ...
V = π(2r)²(h/2) = π(4r²)h/2 = 2πr²h . . . . . double the previous volume
What is the slope of the line y = 2x + 5?
Hello! (:
y=2x-5
This equation is written in slope-intercept form (y=mx+b)
Where
m is the slope of the line (2)
b is the y-intercept (5)
Hope it helps! Please ask if you have any query.
~An excited gal
[tex]MagicalNature[/tex]
The slope of the line y = 2x + 5 is 2 obtained by comparing it with slope intercept form y=mx+b, where m is slope.
The slope represents the rate at which the line is increasing or decreasing as you move along the x-axis.
The slope of a linear equation in the form y = mx + b is represented by "m."
In this case, "m" is 2, which means the slope of the line y = 2x + 5 is 2.
Since the slope is positive (2), it means that as x increases by 1 unit, y increases by 2 units, and as x decreases by 1 unit, y decreases by 2 units.
The slope of 2 indicates that the line is inclined, and it rises at a steady rate of 2 units for every 1 unit moved to the right along the x-axis.
Hence, slope of the line y = 2x + 5 is 2.

The original price of a video game is $32.99 before tax. When Mario bought the video game it rang up as $26.39 before tax. He then paid 8% sales tax on the discounted price.
Part A: What is the percent discount on the game? Show all work and steps in your solution. (5 points)
Part B: What is the total amount that Mario paid for the video game including tax? Show all work and steps in your solution.
Answer:
Part A: The percent discount on game is 20%.
Part B: Mario paid a total of $28.50 including sales tax.
Step-by-step explanation:
Given that:
Part A:
Original price of video game = $32.99
Discounted price = $26.39
Amount of discount = 32.99 - 26.39 = $6.60
Discount percent = [tex]\frac{Amount\ of\ discount}{Original\ price}*100[/tex]
Discount percent = [tex]\frac{6.60}{32.99}*100 = 0.20*100[/tex]
Discount percent = 20%
Part B:
Sales tax = 8% of discounted price
Amount of sales tax = [tex]\frac{8}{100}*26.39 = 0.08*26.39[/tex]
Amount of sales tax = $2.11
Total amount = $26.39 + $ 2.11 = $28.50
Hence,
Part A: The percent discount on game is 20%.
Part B: Mario paid a total of $28.50 including sales tax.
