Answer:

Multiply each side by 14.7

Step-by-step explanation:

cos 50 = m / 14.7

Multiply each side by 14.7

14.7 cos 50 = m /14.7 *14.7

 14.7cos 50 = m

Answer:

multiply both sides by 14.7

You move over two decimal places to the left if you want to convert 35%, which is .35.

You move over two decimal places to the right if you want to convert .45 which is 45%.

Answer:

(if its a true or false question) True

Step-by-step explanation:

We know-

Area of a circle =

A=(π)r2

Circumference of a circle =

C=2(π)r

Where pi is a constant and r is the radius of the circle.

Using these two formulas we can express A in terms of C as follows:

c2=[2(π)r]2

⇒ c2=4[(π)2]r2 ⇒ c2=4(π)[(π)r2]

As (π)r2=A ⇒c2=4(π)A

Therefore:

A=c2/4(π)

Answer:

35%

Step-by-step explanation:

Use photomath it tells you everything.

Answer:

You should multiply the numerator and the denominator by 5. 35%

Step-by-step explanation:

7/20*5/5=35/100

35%

To get from fraction to percent you need the denominator to be 100. To get the denominator 20 to 100 you need to multiply by 5. Then we just take the numerator and add a percent symbol.

You should multiply the numerator and the denominator by 5. 35%

Answer:

3x^2 +8x +3

Step-by-step explanation:

(6x^2 + 8x - 3) - (3x^2 - 6)

Distribute the minus sign

(6x^2 + 8x - 3) - 3x^2 + 6

Combine like terms

3x^2 +8x +3

Answer:

X = 4

Step-by-step explanation:

-5/6x = -10/3

x = -10/3 * -6/5

x = 60/15

x = 4

Answer:

The result for this equation is [tex]x =4[/tex] .

Step-by-step explanation:

Solve the equation for [tex]x[/tex] :

[tex]-\frac{5}{6}x =-\frac{10}{3}[/tex]

[tex]\frac{-\frac{5}{6}x }{-\frac{5}{6} } =\frac{-\frac{10}{3} }{-\frac{5}{6} }[/tex]

[tex]x = 4[/tex]

So, the answer for this equation is [tex]x =4[/tex]  .

Answer:

work is shown and pictured

We have been given that two rectangular prisms, M and N, are mathematically similar. The volumes of M and N are 17 cm^3 and 136 cm^3, respectively. The height of N is 18 cm. We are asked to find the height of M.

First of all, we will find the ratio between sides of rectangle M and N using proportions.

[tex]\frac{\text{Side of N}}{\text{Side of M}}=\frac{\text{ Volume of N}}{\text{ Volume of M}}[/tex]

[tex]\frac{\text{Side of N}}{\text{Side of M}}=\frac{136\text{ cm}^3}{17\text{ cm}^3}[/tex]

[tex]\frac{\text{Side of N}}{\text{Side of M}}=\frac{8\text{ cm}^3}{1\text{ cm}^3}[/tex]

Now we will take cube root on right side to find length in cm.

[tex]\frac{\text{Side of N}}{\text{Side of M}}=\frac{\sqrt[3]{\text{8 cm}^3}}{\sqrt[3]{\text{1 cm}^3}}[/tex]

[tex]\frac{\text{Side of N}}{\text{Side of M}}=\frac{\text{2 cm}}{\text{1 cm}}[/tex]

Therefore, sides of rectangle N is 2 times greater than sides of rectangle M.

To find height of rectangle M, we will divide side of rectangle N by 2.

[tex]\text{Height of rectangle M}=\frac{18}{2}=9[/tex]

Therefore, height of rectangle M is 9 cm.

Answer:

x = 2

Step-by-step explanation:

-2x + 7 = 3

Subtract 7 from both sides

-2x = -4

Divide by -2

x = 2

(Negative divided by negative = positive)

Answer: x = 2

Step-by-step explanation: To solve for x in this problem, the first thing we want to do is subtract 7 from both sides of the equation in order to get our x term by itself.

On the left side, 7 - 7 cancels and here's the tricky part. An extremely common mistake would be to forget to bring down the negative leaving yourself with 2x on the left side.

Be very aware of this mistake so it doesn't claim you as a victim. On the right side of the equation, 3 - 7 is -4.

So we have -2x = -4.

Now divide both sides by -2 so x = 2.

Answer:

This means the store room is 19.15ft up

Step-by-step explanation:

The set up of the question will form a right angle triangle.

The length of the ladder will be the hypotenuse of the triangle and the angle the ladder forms will be the angle of elevation. This angle of elevation will face the opposite side of the triangle which is the height of the storeroom directly.

Using the SOH CAH TOA trigonometry identity,

According to SOH;

Sin∅ = opposite/hypotenuse

∅ is the angle the ladder forms

sin50° = x/25

x = 25sin50°

x = 19.15ft

This means the store room is 19.15ft up

Answer:

12 pitchers

Step-by-step explanation:

Saturday, 6 pitchers

Sunday, same number of pitchers with Saturday, = 6 pitchers

Total pitchers = 6 + 6 = 12 pitchers

Answer:

Cleo sold 6 pitchers of lemonade on Sunday.

Step-by-step explanation:

Cleo sold lemonade at her lemonade stand.

She sold 6 pitchers on Saturday.

On Sunday, she sold as many pitchers as Saturday.

This implies that she sold 6 pitchers too.

She sold 6 pitchers on Saturday, and 6 pitchers on Sunday.

Answer:

The mean of the scores is by adding up all those numbers then dividing by how many there are.

So the answer is 146.6, but if you take away 3 it will be 143.6 then taking away the decimals it'll just be 143, it might be 143 but I might be incorrect.

Answer:

3 1/3 batches

Step-by-step explanation:

you can divide 1/4 and 5/6 to find how many in each batch.

Answer: 25

Step-by-step explanation: In this problem, we're given a diagram and were asked to find the value of x.

Since the two lines in the figure intersect, we know that they form vertical angles and remember that vertical angles are always congruent, or of equal measure.

Therefore, since we know that one angle measures 75° and the other angles measures 3x°, we can setup the equation 75 = 3x.

To get x by itself since 3 is being multiplied by x,

divide both sides of the equation by 3.

On the left, 75 divided by 3 is 25

and on the right, the 3's cancel.

So the value of x in the diagram shown is 25.

Answer: True

Step-by-step explanation:

YES, HE TRAVELLED 2 METRES EVERY 5 SECONDS

PROOF:

TOTAL RIDE TIME = 30 SECONDS

Length of elevator = 12 METRES

Distance moved per second can be calculated by = (length of elevator / total ride time)

( 12 METRES / 30 seconds) = 0.4 metres per second

Therefore, distance covered in 5 seconds :

0.4 × 5 = 2 metres.

Hence, the proof

He traveled 2 meters ever 5 seconds

Answer:

59.62075 (if you use 3.14 for pi) 59.65099051 ( if you just use regular pi)

Step-by-step explanation:

i personally use 3.14 for pi. its just easi×er.

so the surface area formula for a cone is

π [tex]rl[/tex] + π[tex]r^{2}[/tex]

since the formula is looking for radius and not diameter, we change 3.5 to 1.75 (3.5 ÷ 2)

so it would be

(3.14×1.75×9.1) + (3.14×[tex]1.75^{2}[/tex])

which that equals

59.62075

hope this helps!! <3

Remember: volume=length x width x height

So  i think its 15, 15, and neither of them have greater volume.
