Answer:

g = 21

h = 8

Step-by-step explanation:

3g + 5 + 6g - 14 = 180 (since they are adjacent angles and will equal 180)

Simplify to get g = 21.

Substitute 21 for g in 3g + 5 and set that equal to 9h - 4 and solve for h to get 8 (since they are opposite angles and will equal each other)

Answer:g=21 h = 8

Step-by-step explanation:

That's a rhombus supposedly so the opposite angles are congruent.

This means 9h-4=3g+5 Also the opposite sides of a rhombus add up to 180 degrees, so 3g+5+6g-14=180

9g=,189 g = 21

now plug this into the first equation

9h-4=3(21)+5

9h-4=63+5

9h=72

h=8

Jack read 20 pages of a book in 60 minutes. How many pages can he read in 75 minutes at the same rate? Write a proportional equa

AveGali [126]

Answer:

25 pages

Step-by-step explanation:

Create a proportion:

$\frac{pages}{minutes}$ = $\frac{20}{60}$ = $\frac{x}{75}$

Cross multiply and solve for x, the number of pages in 75 minutes:

60x = 1500

x = 25

So, he can read 25 pages in 75 minutes at the same rate

Pattern $y$ : $1,2,4,8$

Step-by-step explanation:

Given:

Pattern x: start with 0 and add 6.

Pattern y: start with 1 and multiply 2.

To find: patterns $x$ and $y$

Solution:

Pattern $x$ : $0,0+6,0+6+6,0+6+6+6=0,6,12,18$

Pattern $y$ : $=1,1(2),1(2)(2),1(2)(2)(2)=1,2,4,8$

A sports broadcaster predicts a basketball team will score 88 points in the next game. If the team actually scored 98 points, wh

Evgesh-ka [11]

Well 88 is 88% and 98% but if you round 88 would turn into 90% and 98 would become 100%. and 100% minus 90% is 10% so the broadcaster had about a 10% error.
I am sure not 100% right because i don't quite know percents yet.
So good luck.

the original cost of an item is $64 but u have to pay $78.08. what is the markup of the item (as percent)

8_murik_8 [283]

(new - original)/original = mark up

(78.08-64)/64= mark up

14.08/64 =mark up

.22 = mark up

multiply by 100 to get to a percent

mark up = 22 percent
