Answer:

19.1

Step-by-step explanation:

Pythagorean theorem: a^2+b^2=c^2

4^2+7^2=c^2

16+49=c^2

C^2=65

c=hypotenuse =root 65

Perimeter =7+4+root65=19.1ft

Answer:

A4t = m - R²

A=m/4t-R²/4t or (m-R²)/4t or 1/4 +(m-R²)/t

Step-by-step explanation:

Answer:

y=5x-12

Step-by-step explanation:

find the slope first which is (8-3)/(4-3)=5

Then that’s your slope.

after that plug the x into the equation I wrote so that means y=5(3)-12 and you should get the y value which is simple enough if you know how to do it.

Answer:

A = 20 degrees

Step-by-step explanation:

Both legs of the triangles are 2x and equal, so we know that the triangle is isoceles. That means both acute angles are equal as well.

In a triangle there are 180 degrees

180 - 140 = 40

40 remainding degrees/ 2 equal angles

A = 20 degrees

Answer:

angle a = 20

Step-by-step explanation:

So like the person above me said

180-140=40

40 divided by 2 is 20

Answer:

Distance between mall and library is 6.32 miles.

Step-by-step explanation:

Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).

Since, distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

By this formula,

Distance between (2, 4) and (8, 4) will be,

Distance = [tex]\sqrt{(8-2)^2+(2-4)^2}[/tex]

               = [tex]\sqrt{36+4}[/tex]

               =  [tex]\sqrt{40}[/tex]

               = 6.32 miles

Answer:

B.

–80, –110

Step-by-step explanation:

-80 and -110

It is an arithmetic sequence. The difference = -30. It is the difference between each number in the sequence: 10-40=-30

-50-30=-80

-80-30 =-110

-80

First Identify the sequence being made here.

10-40 = -30

-20-10 = -30

-50-(-20) = -30

Therefor this pattern is decreasing by a rate of 30 so to continue this, just subtract 30 from -50.

-50-30 = -80

The next term is -80.

Answer:

Step-by-step explanation:

10 times 10 times 60 = 6000

6000 - (1600 + 2000) = 2,400

Answer:

7200 [tex]in^3[/tex]

Step-by-step explanation:

volume of the bottom + volume of the middle part + volume of the top part (I'm sorry this is so vague T-T)

[tex](8*60*10)+(2*40*10)+(8*20*10)= 4800+800+1600=7200[/tex]

Answer:

Step-by-step explanation:

because i mutipled

60 hamburgers

240÷2=120

120 for both each

120÷2=60

so i think its 60 hamburgers

Answer: The correct answer is B. 523.3...cm^3

Step-by-step explanation:

4/3*pi*r^3 is the formula

first, divide the diameter by 2 to get the radius, now, you will begin solving.

4/3*5^3*3.14

5*5*5=125

4/3*125*3.14

125*3.14=392.5

4/3*392.5

523.3...

Answer:

See answers below

Step-by-step explanation:

Standard equation of a line is expressed as y = mx+b

m is the slope

b is the y intercept

Given the coordinate points (-2, -4) and B(1, -7)

Slope m = y2-y1/x2-x1

m = -7-(-4)/1-(-2)

m = -7+4/1+2

m = -3/3

m = -1

Get the intercept

Substitute m = -1 and (1, -7) into y = mx+b

-7 = -1(1) + b

-7 = -1 + b

b = -7+1

b = -6

Get thw equation

y = mx+b

y = -x + (-6)

y = -x - 6

Q.3 The equation in point slope form is expressed as y - y0 = m(x-x0)

Given the point (3, 5)

x0 = 3

y0 = 5

Given the equation y = 2x+3

mx = 2x

m = 2

slope = 2

Substitute the slope and the point in the expression

y - 5 = 2(x -3)

y - 5 = 2x - 6

y - 2x = -6 + 5

y - 2x = -1

This gives the required equation

Q.4 The equation in point slope form is expressed as y - y0 = m(x-x0)

Given the point (5, 7)

x0 = 5

y0 = 7

Slope = 3

Substitute the slope and the point in the expression

y - 7 = 3(x -5)

y - 7 = 3x - 15

y - 3x = -15 + 7

y - 3x = -8

This give the required equation

Answer:

10.5.

Step-by-step explanation:

By similar  triangles:

IJ / 21 = 8 /(8+8) = 1/2

IJ / 21 = 1/2

IJ = 1/2 * 21

= 10.5.

Answer:

The whole = 48

The percentage = 78%

The part = 37.44

Step-by-step explanation:

The given parameters are;

The number of responses for the competition = 48 responses

The percentage that voted for the black T-shirt = 75%

The whole = The total number of responses for the competition = 48

The percentage = 78% = The part/(The whole) × 100

The part = The missing information

To find the part, we substitute the values of the whole, and the percentage into the given following equation

The part = The percent × The whole

∴ The part = 78% × 48 = 78/100 × 48 = 37.44

The part = 37.44.

Answer:

the answer for this problem is x^2+2x-15

Step-by-step explanation:
