Answer:
274.05 (I assume they round it to A. 274.1)
Step-by-step explanation:
The figure seems to be comprised of 7 triangles, each of base 8.7 and height 9.
total area would be
7 * (8.7 * 9 / 2) = 7 * 39.15 = 274.05
Write 24:14:6 in its simplest form.
Answer:
12 : 7 : 3
Step-by-step explanation:
24 : 14 : 6
12 : 7 : 3
Always start with smaller number to simplify it. Since 2 is the smaller number and it simplifies 24, 14, and 6 I start with it.
24 ÷ 2 = 12
14 ÷ 2 = 7
6 ÷ 2 = 3
We would stop here since it would not further simplify, therefore our answer is 12 : 7 : 3.
Hope this helps, thank you :) !!

Rodell wants to find the favorite gaming app among the students at his school. He decides to poll the thirty students on his football team and the fifteen students on his basketball team to gather the data. What is wrong with Rodell’s method for collecting his data?
Rodell only polled fellow athletes; this sample does not represent nonathletes at the school.
Rodell needs a larger sample size than two sports teams to represent a whole school.
Rodell polled everyone on his teams; he should have only polled every other student for it to be a true sample.
Rodell’s polling method only included fall and winter sports; he should have also included a spring sport like baseball.
Using sampling concepts, it is found that the due to bias, the correct option is given by:
Rodell only polled fellow athletes; this sample does not represent nonathletes at the school.
Why is Rodell's sample biased?The school is composed both by athletes and non-athletes, which should have different gaming apps, for example, athletes may be more likely to play sports games while non-athletes may favor RPG for example.
He surveys only athletes, hence, the correct option is:
Rodell only polled fellow athletes; this sample does not represent nonathletes at the school.

Answer:
5. 8.49
6. 8.6
7. B. Joe is taller than the tepee
Step-by-step explanation:
5 - formula for diagonal [tex]d= \sqrt{2} *s[/tex] s= side length
So 1.4 times 6 = 8.49
6 - Pythagorean Theorem [tex]c= \sqrt{ a2+b2}[/tex]
So [tex]c= \sqrt{ 5 *2+7*2 }[/tex] c = 8.6
7 - Formula for height [tex]h= \sqrt{ l^{2} - r^{2}[/tex] l=slant height
So [tex]\sqrt{ 7^{2} - 4^{2}} =h\\\sqrt{ 49-16} = h\\h = 5.74\\5.74 < 6[/tex]That means Joe is taller
Answer:
The answers to your questions are :
5. Area of square = 36 , so (4 × X =36) . X=9
The formula used to find diagonal length = side × Rad2
9 × rad2 = 12.72
6 . Rad ( 25+49) = Rad(74) = 8.6
7. B is correct . He is taller than it .
Rad ( Slant height^2 - radius^2 ) = hight
hight = 5.7 .

Find the Volume of the figure. Write the answer in terms of pi.
Answer:
Step-by-step explanation:
[tex]\text{The volume of a cone is}\\ \\ V=\frac{h\pi r^2}{3},\ h=7mi,\ r=2mi\\ \\ V=\frac{7\pi 2^2}{3}\\ \\ V=\frac{28\pi }{3}mi^3[/tex]
Answer:
answer 29.32
Step-by-step explanation:
3.14x2^2 is 12.56 then 12.56x7/3=29.32 because the formula for cone is V=πr2h 3
Your parents car initially costs $18,000 and it depreciates at a rate of 12% a year. How much will the car be worth after 5 years.
Using this equation, when your parents give you the car when the value drops below $2,000, in what year of depreciation will you become the owner?
Answer:
Step-by-step explanation:
value after five years = $18,000×(1-0.12)⁵ = 18,000×0.88⁵ = $9,499.17
:::::
The value drops below $2,000 in the 17th year.

A ladder is placed 7 feet from the base of a building and reaches a point on the building that is 24 feet above the ground. Find the length of the ladder.
Use the Pythagorean theorem:
7^2 + 24^2 = length^2
Simplify:
49 + 576 = length ^2
Add:
625 = length^2
Take the square root of both sides
Length = 25
The ladder is 25 feet long

Answer:
52.48x ≤ 288.64
x≤5.5, x=5
Step-by-step explanation:
First off, we must find out how much money he has available after buying the bike, reflectors and gloves:
Total spent = (price of bike)+3(price of reflectors)+(price of gloves)
=233.09+3(16.38)+29.13
=311.36
600-311.36=288.64, so he has $288.64 left to spend on outfits.
The cost of x amount of outfits is found by multiplying the amount of outfits, x, by the cost per outfit, 52.48: 52.48x. Since he can only spend up to $288.64, 52.48x must be less than or equal 288.64:
52.48x ≤ 288.64
To solve, divide both sides by 52.48:
x≤5.5
(Since he cant buy half of a product, x's maximum value is 5)

What is the value of x in the equation 2.5(6x - 4) = 10 + 4(1.5 +0.5x)?
13
Submit
Answer:
x=2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable :)
The value of x in the equation is 2.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
2.5(6x - 4) = 10 + 4(1.5 +0.5x)
Now,
To solve for x, we need to simplify the equation and isolate x on one side. Here are the steps:
Distribute 2.5 and 4 on the left and right sides respectively:
15x−10=10+6+2x
Combine like terms on both sides:
15x−10=16+2x
Subtract 2x from both sides:
13x−10=16
Add 10 to both sides:
13x=26
Divide both sides by 13:
x=1326
Simplify the fraction:
x=2
Therefore, by the equation the answer will be 2.

Given:
HML = 180°
KMG = 180° (since both are lines)
∠KML = 83°
To find:
Measurement of ∠KMH
Steps:
Since we know HML is a line and equals to 180°, then
∠LMK + ∠KMH = ∠HML
83° + ∠KMH = 180°
∠KMH = 180° - 83°
∠KMH = 97°
Therefore the measurement of ∠KMH is 97°
