loris [4]2 years ago

5 0

Answer:

see below

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates together and divide by 2

(5+7)/2 = 12/2 =6

If that was supposed to be -7

(5-7)/2 = -2/2 =-1

To find the y coordinate of the midpoint, add the y coordinates together and divide by 2

(-3+-5)/2 = -8/2 =-4

Either (6,-4) if +7 or (-1,-4) if -7

Lynn has a box of crayons.

Scrat [10]

Answer:

There are 72 crayons in the box

Step-by-step explanation:

Fractions

To solve this problem we'll manage numbers as fractions to keep the precision up to the end of it.

Lynn has a box of crayons. It's given 4/9 of the crayons are blue. The remaining crayons are:

$1-\frac{4}{9}=\frac{5}{9}$

From that portion, 65% are red, or equivalently, 35% are yellow.

We write 35% as a fraction:

$\displaystyle 35\%=\frac{35}{100}=\frac{7}{20}$

Thus, the portion of yellow crayons is:

$\displaystyle \frac{7}{20}\cdot \frac{5}{9}=\frac{7}{36}$

This fraction of x crayons is equal to 14, thus:

$\displaystyle x=\frac{14}{\frac{7}{36}}=14\cdot\frac{36}{7}$

x = 72

There are 72 crayons in the box

How do you solve this?

natali 33 [55]

Not sure if you wanted answers or explanation on what to do. Ill just do the explanation and if you want the answers just lmk C:

R=1/2 d, and C=pi*2r. So you basically take the given number and plug it into these formulas.

today a boat valued at $45,000.Thebvalue is expected to decrease at a rate of 8.5% each year.What is the value of the boat expec

Stels [109]

Current value of the boat = $45000

Rate at which the value decrease = 8.5%

Value decreased after 1 year = $\frac{8.5}{100}\times45000=3825$
