in a school with 400 student , 22% are sixth graders . How many students are in the sixth grade?

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

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)

$18.50 + $6.75x=

and then for 4 hours it would be $45.50

Answer:

she needs to put in 5 more cups of sugar.

Step-by-step explanation:

in the word problem it states that shee needs 7 cups of sugar and since she already put in 2 cups, you have to subtract 2 from 7 since she already put 2 cups in, and then you get your answer which is 5 more cups.

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:

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 .

Answer:

324 °

Step-by-step explanation:

Answer:

324

Step-by-step explanation:

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°

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 :) !!
