Answer:

longer:20 shorter:9

Step-by-step explanation:

Answer:

D - 9 students

Step-by-step explanation:

For this problem, you need to find the percentage of students left. Subtracting all the percentages you already know, you get 100 -  30 - 20 - 10 - 10, or 30. Since there are 30 students in the class, 30 percent of 30 is 9 students.

Hopefully this helps- let me know if you have any questions!

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 :) !!

Answer:

71.4

Step-by-step explanation:

cos 6 = 71 / x = 71.4

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.

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.

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)

Answer:

the value will fall below $3000 in the 7 th year because :

Step-by-step explanation:

15% of 13500 is 2025

On subtracting 2025 from 13500 every time we can see that the value keeps dropping.

So, we will get $3375 in year 6 and in year 7 we will get $1350 by subtracting 2025 from 3375.

Hence we will get 1350 at the 7th year.

After 6.79 years, the car's value will drop below $3,000.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, The following is a representation of the exponential function to model the car's value:

V(t) = 13500 (1 - 0.15)ⁿ

V(t) = 13500(0.85)ⁿ

Here, V(t) denotes the car's worth at time n in years, and 0.85 denotes the annual depreciation rate of 15%.

Hence, The following equation can be put up to determine when the car's value will drop below $3,000:

13500(0.85)ⁿ = 3000

As we solve for n, we obtain:

n = (log(3000/13500)/log(0.85))

n = 6.79

So, after roughly 6.79 years, the car's value will drop below $3,000.

#SPJ2

Answer:

Step-by-step explanation:

there are two ways to solve systems of equations,  elimination or substitution, this looks like elimination would work quickly

x= 25 -y

x + y = 25   (eq 1)

5x + y = 10  (eq 2)

subtract 2 from 1

x + y = 25  

-(5x + y = 10)

-4x + 0y = 15

-4x = 15

x = - 15/4

now plug in x into either starting equations and solve for y

-15/4 + y = 25

y = 25 + 15/4

y = 100/4 + 15 /4

y = 115 /4

y = 28 3/4

we have solved it :)

Answer:

5x+ y = 10   ---(eq1)

x = 25 - y    ---(eq2)

substituting (eq2) in (eq1)

5(25 - y) + y = 10

125 - 5y + y = 10

125 - 4y = 10

-4y = 10 - 125

-4y = -115

4y = 115

y = 115/4 = 28.75

substituting value of y in (eq2)

x = 25 - 28.75

x = -3.75

Answer: y=0

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 .
