#11 solve the equation78 = -2(m + 3) +m

Mathematics
1 answer:
Goshia [24]3 years ago

M = -84

To find this, here are the steps

78 = -2 (m+3) + m
78 = -2m - 6 + m
78 = -m - 6 
Add 6 to both sides now
84 = -m
Divide by the negative on both sides and
-84 = m

Hope this helps!

Answer:

The scores in order from least likely to most likely is 8, 3, 4, and 5.

Step-by-step explanation:

1. Calculate the probability of the spinner adding up to 1, 2, 3, 4, .... 8

You will get:

2 (1/16)

3 (2/16)

4 (3/16)

5 (4/16)

6 (3/16)

7 (2/16)

8 (1/16)

2. Given the scores from the problem, the probability of each number is 3 (2/16), 4 (3/16), 5 (4/16), and 8 (1/16).

3. With this, we can determine the scores in order from least likely to most likely is 8, 3, 4, and 5.

Find the arc length of the semicircle. Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal
cricket20 [7]

Answer:

The arc length of the semicircle is 5 \pi\ units or 15.7\ units

Step-by-step explanation:

The complete question in the attached figure

we know that

The circumference of a semicircle is given by the formula

C=\frac{1}{2}\pi D

where

D is the diameter of the semicircle

we have

D=10\ units

substitute

C=\frac{1}{2}\pi (10)

C=5 \pi\ units ----> exact value

Assume

\pi =3.14

C=5(3.14)=15.7\ units ----> approximate value

therefore

The arc length of the semicircle is 5 \pi\ units or 15.7\ units

When sales of a particular hybrid automobile reach 60,000 units, federal income tax credits begin to phase out. One year after r
SCORPION-xisa [38]

Answer:

$750

Step-by-step explanation:

so, in short, we need to calculate 25% of $3000.

that is the amount of tax credit a buyer would get then.

direct and fast answer :

25% means 1/4 of the overall amount.

$3000 / 4 = $750

now, a little bit longer to explain % calculations in general.

let's say, we are talking 27%. now we have a problem to find a fast fraction as factor.

it always starts with the identification of 100%.

what is the full starting amount we are dealing with ? that is the 100%.

in our case $3000.

now, as a base for the calculation we determine 1%, which is 1/100 of 100%, of course.

1% = $3000 / 100 = $30

to get said 27% we have to multiply this by 27

27% = 1% × 27 = $30 × 27 = $810

or in general

x% = 100% × x / 100

that also works for more complex questions. e.g. calculate 1.5%

1.5% = $3000 × 1.5 / 100 = $30 × 1.5 = $45

and that is all there is to % calculations. all the questions are just some variations, where your are missing one of the 3 "ingredients" : 100% amount, x% amount and x itself.

and you need to transform the general equation above to get the missing piece of of the given information.
