hey does anyone know the answer to this? please. i really don’t know what i’m doing and completely depend on the internet for answers. if yk an app or website that helps with these type of problems lmk

Answer:

  25 = c

Step-by-step explanation:

You had a good start on filling in the values in the Pythagorean Theorem. The work needed to be finished.

  [tex]a^2 +b^2 = c^2\\\\20^2 +15^2=c^2\\\\400+225=c^2\\\\625=c^2\\\\\sqrt{625}=\sqrt{c^2}\\\\\boxed{25=c}[/tex]

Answer:

B

Step-by-step explanation:

The table shows the ratio 1:7 pretty well

Answer:

Step-by-step explanation:

I'll give you a guide — use the formula

[tex]y = mx + b[/tex]

For Question 1, [tex]y = \frac{2}{3}x + 2[/tex]

[tex]y = mx + b[/tex]

So,  m = [tex]\frac{2}{3}[/tex]  and  b = 2

For question 3,

[tex]y = mx + b[/tex]

if  m = [tex]\frac{1}{3}[/tex]  and  b = 3

[tex]y = \frac{1}{3}x + 3[/tex]

For the graphs, You label the center as 0, and go up/down 1 right to left and up down

You use every number on the x-axis (horizontal left-right line) and put it in your equation (e.g. [tex]y = \frac{2}{3}x + 2[/tex]) to get the value for the y-axis.

Let the number be x

We use addiition sign

The expression is x+15

Answer: As a result, the angle between m and n is 45 degrees.

Answer:

$860(860×12×8×1190÷100)

Answer:

$62.50

Step-by-step explanation:

Answer:

6in³

Step-by-step explanation:

get the volume by the formula: L x W x H

L = Length

W = Width

H = Height

there are 3 units required to know for getting the volume, if that's true, then, do the inverse operation of finding the volume. That can be done by using the formula:

a= edge

Solving for a

a=V⅓=216⅓=6

So each of the Cube shaped Fish Tank is 6in³

to find out if  the answer is right or wrong we have to do

6x6=36

36x6=216

So the answer is right!

1. 1 hour = 60 minutes

We convert 3 hours and 25 minutes to minute : 3 x 60 + 25 = 205 (minutes). Since 205 < 230, it took longer to get home than getting to the beach.

2. (Same convertion)

5 hours and 10 minutes = 5 x 60 + 10 = 310 (minutes)

So, the last day rained longer than the day before it.

3. 1 day = 24 hours.

We convert 3 days to hours : 3 x 24 = 72 (hours)

Since 72 > 68, Wendy's family lost their power longer than their neighbors.

4. 1 minute = 60 seconds

Convert 2 minutes and 2 seconds to seconds : 2 x 60 + 2 = 122 (seconds)

Since 122 > 121, it means Paul took longer to finish his race, which mean Jeff finished first (Rip Paul)

5.

Question : Bob bought 2 pizzas for him and his friend, Kevin. They both ate 1 pizza. Bob finished his pizza in 6 minutes and 45 seconds. Kevin finished his pizza in 400 seconds. Who finished first?

Solution : Convert 6 minutes and 45 seconds to seconds : 6 x 60 + 45 = 405 (seconds)

Since 405 > 400, Bob took longer to finish his pizza -> Kevin finished first.

Answer:

-5/2

Step-by-step explanation:

x= -b/2a

x= -6/4= -3/2

y=2×(9/4)+6(-3/2)+2= -5/2

Answer:

Step-by-step explanation:

x^2 + 3

The domain is All Real x and the range is f(x) ≥ 3.

Find its inverse:

y = x^2 + 3

x^2 = y - 3

x = √(y - 3)

So f-1(x) = √(x - 3)

The domain is x  ≥ 3  and range is f(x) ≥ 0.

The set of transformation that has been performed on triangle ABC

to form triangle A'B'C' is " Dilation by a scale factor of 2 followed by

reflection about the x-axis " ⇒ 2nd answer

Step-by-step explanation:

Lets revise some important rules

The corresponding sides of similar triangles have constant ratio

Dilation makes a triangle and its image similar

Reflection about x-axis change the sign of the y-coordinate of a point after reflected about the x-axis

Δ ABC and Δ A'B'C are similar after set of transformations has been

performed on Δ ABC to form Δ A'B'C'

∵ The vertices of triangle ABC are:

A = (-2 , -1) , B = (0 , 0) , C = (1 , -3)

∵ The vertices of triangle A'B'C' are:

A' = (-4 , 2) , B' = (0 , 0) , C' = (2 , 6)

∵ x-coordinate of point A = -2 and x-coordinate of point A' = -4

∵ y-coordinate of point A = -1 and y-coordinate of point A' = 2

∵ x-coordinate of point B = 0 and x-coordinate of point B' = 0

∵ y-coordinate of point B = 0 and y-coordinate of point B' = 0

∵ x-coordinate of point C = 1 and x-coordinate of point C' = 2

∵ y-coordinate of point C = -3 and y-coordinate of point C' = 6

∵ Each coordinate of the vertices A , B , C is multiplied by 2 to give

 the coordinates of the of the vertices A' , B' , C'

∴ Δ ABC is dilated by scale factor of 2

∵ The signs of y-coordinates of the vertices A , B , C is opposite to

  the signs of y-coordinates of the of the vertices A' , B' , C'

∴ Δ ABC is reflected about the x-axis

The set of transformation that has been performed on triangle ABC

to form triangle A'B'C' is " Dilation by a scale factor of 2 followed by

reflection about the x-axis "

Step-by-step explanation:

cup of sugar used for 3/4 cup of flour = 1/2

cup of sugar used for 1 cup of flour = 1/2*4/3 =2/3

Answer:

Solution 1 : 10mL with 20% acid

Solution 2 : 30mL with x% acid

Solution 3 : 40mL with 32% acid

Step-by-step explanation:

Since solution 1 + solution 2 = solution 3, let us substitute the given values we have:

10(0.2) + 30(x) = 40(0.32)

2 + 30x = 12.8

To solve for the unknown concentration x, we subtract 2 from both sides:

2 + 30x - 2 = 12.8 - 2

30x = 10.8

Dividing both sides by 30:

30x/30 = 10.8/30

x = 0.36

Therefore the unknown solution is 36% acid.

Answer:

The first option (30c + 10(0.2) = 40(0.32)

slant height

Step-by-step explanation:

slant height of a pyramid is defined as a distance measure along a lateral face from a base of a triangle because hypotenuse of a right angle triangle is half on the base

distance from the center of the base to the point where the slant height segment

The line AB in the pyramid is the slant height of the pyramid.

A pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex.

Given is a pyramid with AB labelled at one of its face, we need to determine the name for AB,

So, here AB is the slant height.

Slant height of a pyramid is defined as a distance measure along a lateral face from a base of a triangle because hypotenuse of a right angle triangle is half on the base distance from the center of the base to the point where the slant height segment.

Hence, the line AB in the pyramid is the slant height of the pyramid.
