15 less than or equal to (the < and the _ underneath but I can't type it) 7.75 + .5x

let x represent the number of rides you can take

Find the measure of angle X.

densk [106]

Answer:

x = 23 degrees

Because if you look at diagram x is vertical to angle FBC, and angle FEC and angle EBA are alternate interior angles so they are equal to each other, and AC is a straight line which means it equals to 180 degrees.

$4x+65+x = 180$

x = 23 degrees

HELP ME WITH MY MATH ASSIGNMENT, WILL GIVE ANYTHING, DUE TOMORROW! :(

nataly862011 [7]

Answer:

Answer is 225.

We have to find the sum of 15 terms of the series

sigma 1 to 15 (2n-1)

This can be split as per summation terms as

sigma 2n - sigma 1

sigma 2n can again be simplified by taking 2 outside

sigma 2n= 2 times sum of natural numbers of 1 to 15

= 2(15)(16)/2= 240

sigma 1= 1+1+...15 times= 15

Hence final answer is

= 2 times sigma n - (n) = 240-15 = 225.

4 liters of punch can serve 16.

5 liters of punch will be needed for 20 servings.

7 liters of punch will serve 28.

Step-by-step explanation:

Given,

Ratios of liters of punch to servings = 2:8

Let,

x be the servings for 4 liters.

New ratio of liters of punch to servings = 4:x

Using proportion;

Ratio :: New ratio

$2:8::4:x$

Product of mean = Product of extreme

$8*4=2*x\\32=2x\\2x=32$

Dividing both sides by 2

$\frac{2x}{2}=\frac{32}{2}\\x=16$

4 liters of punch can serve 16.

Let,

y be the liters of punch for 20 servings.

New ratio = y:20

Using proportion;

$2:8::y:20$

Product of mean = Product of extreme

$8*y=20*2\\8y=40\\$

Dividing both sides by 8

$\frac{8y}{8}=\frac{40}{8}$

y=5

5 liters of punch will be needed for 20 servings.

Let,

z be the number of servings for 7 liters of punch.

New ratio = 7:z

Using proportion

$2:8::7:z\\$

Product of mean = Product of extreme

$8*7=2*z\\56=2z\\2z=56$

Dividing both sides by 2

$\frac{2z}{2}=\frac{56}{2}\\z=28$

7 liters of punch will serve 28.
