Answer:

25m + 10b = 400

Step-by-step explanation:

Total amount that can be earned = $ 400

Amount earned on mowing a lawn = $ 25

Amount earned per hour on babysitting = $10

Amount earned for mowing one lawn is $ 25, so amount earned for mowing m lawns will be $ 25m

Amount earned for one hour of babysitting is $ 10, so amount earned for babysitting for b hours will be $ 10b

Total amount earned = Amount earned from mowing m lawns + Amount earned from babysitting for b hours

Using the values from above, we can set up the equation as:

400 = 25m + 10b

Answer:

30 in^3

Step-by-step explanation:

Radius = 1/2 D; 2/2 = 1

(3)(1^2)(10) = 30

Answer:

a) m + n + e3 + ( -2n)  +  10m  =  11m - n + e3

b) x + 2y -4y + 6x + 2x = 9x -2y

c) a + b + c + 2a + 3c -2a + 3b + 4c = a + 4b + 8c

d) 2a  -b + 3c -2a + 3b + 2c = 2b + 5c

Step-by-step explanation:

En cada uno de los casos:

1) Reorganizas los términos

2) sumas los coeficientes de los términos semejantes

a)  m + n + e3 + ( -2n)  +  10m

1) Reorganizando los términos

m + 10m + n + ( -2n)  + e3

2) Sumando los coeficientes de los términos semejantes

(1 + 10) m + (1 - 2) n + e3

(11)m + (-1)n + e3

11m - n + e3

b)  x + 2y - 4y + 6x + 2x

1) Reorganizando los términos

x + 6x +2x + 2y - 4y

2) Sumando los coeficientes de los términos semejantes

(1 +6 +2) x + (2- 4) y

(9) x + (-2)y

9x -2y

c)  a + b + c + 2a + 3c -2a + 3b + 4c

1) Reorganizando los términos

a + 2a - 2a  + b + 3b + c + 3c + 4c

2) Sumando los coeficientes de los términos semejantes

(1 + 2 - 2 ) a + (1  +3) b + ( 1 + 3 +4) c

(1) a + (4)b + (8)c

a +4b + 8c

__________________

d)  2a -b + 3c -2a + 3b + 2c

1) Reorganizando los términos

2a - 2a - b + 3b + 3c +2c

2) Sumando los coeficientes de los términos semejantes

(2 - 2) a + (-1 +3) b + (3 +2)c

(0) a + (2) b + (5) c

2b + 5c

Answer:

0.25

Step-by-step explanation:

Well assuming the result of the spin is uniformely random, the yellow area will come up 1/2 of the time (because it takes up 1/2 of the figure).

If it needs to land on yellow both times in two spins, we can take it step by step.

The probability it lands on yellow after the first spin is 0.5

The probability it lands on yellow and then lands on yellow again is 0.5 * 0.5 = 0.25

Think of both spins as 50% yellow, 50% non-yellow

We have 4 options

yellow, yellow

yellow, non-yellow

non-yellow, yellow

non-yellow, non-yellow

Each option is equally probable, so the probability of "yellow, yellow" is 0.25

Answer:

It is D

Step-by-step explanation:

Within each coordinate it represents (x,y)

The x moves along the horizontal line and the Y moves along the vertical line.

For example: For (-5,5) move to the left 5 times, then move up 5 times.

A negative X goes to the left and a negative Y goes down.

A positive X moves to the right and a positive Y moves up.

First of all are you given formulas, if yes then apply them to what you are given and find the missing outputs. I'm writing a test tomorrow on Euclidean Geometry

Answer:

90%

Step-by-step explanation:

there are 100 % if you multiplied 10 by 10 you get that 100 % so multiply 9 by 10 to get 90 and that is your answer

Answer:

$90%

Step-by-step explanation:

90/100 *10.

9*1

$9%

Answer:

Loss= $175

Loss %= 7%

Step-by-step explanation:

First of all, you find the difference between 2500 and 2325 which is 175, as his has decreased, it is a loss of $175

To find the percentage you do the difference over the original amount

So 175/2500 which will give you 0.07

0.07 x 100 will give you 7%

Answer:

2

Step-by-step explanation:

ΔX = -1 – 2 = -3

ΔY = -4 – 2 = -6

-6 divided by -3=2

Hope it helps ;)

Step-by-step explanation:

[tex]slope = \frac{y2 -y1 }{x2 - x1} \\ = \frac{ - 4 - 2}{ - 1 - 2} \\ = \frac{ - 6}{ - 3} \\ = 2[/tex]

even if x₁ = -1, y₁ = -4 and x₂ = 2, y₂= 2 the result remains the same.

Answer: The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.

Step-by-step explanation:

What is the probability of choosing a pen from the first box? It is 5/8.

What is the probability of selecting a crayon from the second box? It is 3/12 = 1/4.

The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.

Answer:

slope = 4

y intercept = -3

Step-by-step explanation:

The equation is put in slope intercept form

Slope intercept form: y = mx + b

where m = slope and b = y intercept

looking at slope intercept form

4 is located where m should be , meaning that the slope is equal to 4 and

-3 is located where b should be , meaning that the y intercept is -3

Therefore the answers are the first and last option choices.

Answer:

50

Step-by-step explanation:

70+60 =130

180-130 = 50 degrees

Answer: 50

Step-by-step explanation: Every triangle is 180 degrees so add the 60 and the 70 to get 130. 180-130=50. So 50 is your answer.
