PLEEEEEAASE HELP IM GIVING 100 POINTS TO WHOMEVER DOES THIS ENTIRE WORKSHEET

Answer:

m = 5

Step-by-step explanation:

Rewrite problem

m + 2m + -4m = -5

Combine like terms

-1m = -5

Divide -1 on both sides

-1m = -5/-1

m = 5

Check answer

5 + 2(5) +-4(5) = -5

5+ 10 + -20

-5 = -5

Hope this helps :)

Answer:

63

Step-by-step explanation:

use tangent formula

[tex] \tan(40) = \frac{h}{75} [/tex]

Answer:

h ≈ 62.9 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{75}[/tex] ( multiply both sides by 75 )

75 × tan40° = h , then

h ≈ 62.9 ft ( to 1 dec. place )

branliy app is very bad and poor,

Answer:

$3000

Step-by-step explanation:

Look at where the x value is equal to 100 and look at what value the purple line intersects with when it reaches 100

you can see that when the purple hits 100 it is also on the 3000 line

Answer:

f(-2)=3(-2)-4

=f(-2)=-10

Answer:

2

Step-by-step explanation:

[tex]\begin{cases} -3x -3\:\: for\:\: x<-2\\\\6x -28\: \: for\:\: x\geq 5  \end{cases}[/tex]

f(5) will fall in the interval x≥5 and its corresponding function is:  

    f(x) = 6x - 28

∴ f(5)= 6*5 - 28 = 30 - 28 = 2

Answer:

a baby weight more because the baby will grow and will weight more then a puppy

Step-by-step explanation:

Answer:

A puppy that weights 8.5 kilograms weighs more.

Step-by-step explanation:

A puppy that weights 8.5 kilograms weighs more. Why? Well if you convert the 11 pounds from the baby to kilograms it would equal about 5 kilograms. The puppy's weight in kilograms is 8.5 and its weight in pounds is 18.7, while the baby's weight in kilograms is 5 and it's weight in pounds is 11.

Puppy's Weight Kilograms: 8.5

Puppy's Weight Pounds 18.7

Baby's Weight Kilograms: 5

Baby's Weight Pounds: 11

Weight in Kilograms: Puppy: 8.5 > Baby: 5

Weight in Pounds: Puppy: 18.7 > Baby: 11

Therefore, the puppy is heavier.

Answer:

the mean is 3.95

median is 2.75

Step-by-step explanation:

I'd say that the mean is the better center, because you need to even it all out. you have one big number compared the rest.

The median is a better center for this data since since that number is the common size of acres not the highest or lowest acre per 1000 residents

Answer:

(4,0)

Step-by-step explanation:

(5,3) (1,3)

You need to subtract from the x axis on both coordinates and the y axis in both coordinates.

(5-1) (3-3)

(4,0)

I also checked on a graph as well, so it's correct.

Answer:

c

Step-by-step explanation:

Answer:

The answer is A

Step-by-step explanation:

7 + -8 = -1

-6 + -7 = -13

2 + 5 = 7

6 + -1 = 5

-5 + -9 = -14

-7 + 7 + 0

you can then eliminate B.

and only A is left.

Answer:

The volume of the solid is 19.[tex]\overline{142857}[/tex] unit³

Step-by-step explanation:

The given function is y = x³

The solid is created by revolving R about the line y = 1

We have that when y = 1, x = 1

Taking the end point as x = 2, we have the volume given by the washer method as follows;

[tex]V = \pi \cdot \int\limits^a_b {\left( [f(x)]^2 - [g(x)]^2 \right)} \, dx[/tex]

Where;

a = 1, and b = 2, we have;

g(x) = 1

[tex]V = \pi \cdot \int\limits^{2}_1 {\left( [x^3]^2 - [1]^2 \right)} \, dx = \pi \cdot \left[\dfrac{x^7}{7} + x \right]_1^{2} = \pi \cdot \left[\dfrac{2^7}{7} +2 -\left( \dfrac{1^7}{7} + 1\right)\right] =19\dfrac{1}{7}[/tex]

The volume of the solid, V = [tex]19\dfrac{1}{7}[/tex] unit³ = 19.[tex]\overline{142857}[/tex] unit³

Answer:

x = 0 and y = 4.

Step-by-step explanation:

The given equations are :

4x+2y=8 ...(1)

x+y=4 ...(2)

Multiply equation (2) by 2.

2x+2y=8 ...(3)

Subtract equation (3) from (1).

4x+2y-(2x+2y)=8-8

4x+2y-2x-2y=0

2x = 0

x = 0

Put the value of x in equation (2).

0+y=4

y = 4

So, the value of x and y are 0 and 4.

Answer:

0.87

Step-by-step explanation:

Out of a total number of 100 questions, Daniel is said to have answered 87.

We first express this as a fraction.

Total number of questions he answered divided by total number of quiz questions

= 87/100

As a decimal, 87 divided by 100 = 0.87.

You can easily get this by using the calculator.

Thank you!

Answer:

Step-by-step explanation:

0.87 because 87+0=87

Answer:

HCF = 14

LCM = 1680

Step-by-step explanation:

Factorizing the given values

210 = 2 * 3 * 5 * 7

112 = 2 * 2 * 2 * 2 * 7

Since 2 * 7 is common to both factors

Hence the HCF = 2 * 7 = 14

For LCM, we we will multiply all the prime factors that are in both

LCM = 2* 2 * 2 * 2 * 3 * 5 * 7

LCM = 112 * 15

LCM = 1680

Hence the LCM is 1680

Answer:

10,980

Step-by-step explanation:

Answer:

$0.84 I think is the answer

Answer:

If y = 80 then 5x+36 also equals 80

80 - 36 = 44

therefore 5x = 44

44 / 5 = 8.8

x=8.8

Answer:

40

Step-by-step explanation:

Hi there,

Before solving this problem, it is useful to know that 25% is equivalent to 1/4 or 0.25. There are two ways to solve this problem:

1.) Multiply 0.25 by 160

or

2.) Divide 160 by 4.

Either way, the answer is still 40. Hope this answer was useful. Cheers.

Answer:

Let the length of shorter piece be 3x and length of longer piece be 5x (THEIR RATIO IS 3:5)

Now, length of longer piece is 20 cm

So,

5x=20

x=4

Hence, length of shorter piece = 3x = 3*4=12 cm
