11. What is the reflection image of (5, -3) across the line y = -x?

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:

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]  .

Side CD has a length of 11.67

[tex]\text{Find the one bottom side of the triangle first}\\\\\text{We know that the total length is 21, but part of it is 11, so subtract}\\\\21-11=10\\\\\text{Divide 10 by 2 because there are two sides for two triangles}\\\\10\div2=5\\\\\text{Now, since we know two of the sides, we would plug in the values}\\\text{into the Pythagorean theorem and solve:}\\\\5^2+b^2=13^2\\\\25+b^2=169\\\\\text{Subtract 25 from both sides}\\\\b^2=144\\\\[/tex]

Step-by-step explanation:

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:

Step-by-step explanation:

Here, we are interested in calculating the ratio of diameter of ball A to that of ball B

what to do here is to ensure that both diameters have measurements that are same units.

Thus, mathematically;

44 mm to 7.2cm

But, mathematically;

10 mm = 1 cm

Thus 7.2cm = 7.2 * 10 = 72mm

Thus, our ratio becomes;

44:72

divide through be 4, we have

44/4 : 72/4

= 11 : 18

Answer:

yes that's the answer because the volume of a cylinder= πr²h and the volume of a cone =1/3πr²h

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:

(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)

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.

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:

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

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: 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
