Answer:
x = 27°
Step-by-step explanation:
Each exterior angle is equal to the sum of the remote interior angles.
6x = 90° +(180° -4x)
10x = 270° . . . . . add 4x
x = 27° . . . . . . . . divide by 10
_____
Check
6x = 162°, so the adjacent interior angle of the triangle is 180° -162° = 18°.
4x = 108°, so the adjacent interior angle of the triangle is 180° -108° = 72°.
The interior angles of the triangle are complementary, as they should be.
18° +72° = 90°
A 9 foot flagpole cast a shadow 6 feet long, and at the same time a nearby tree cast a shadow 14 feet long. What is x the hight of the tree.
The height of the nearby tree is 21 feet.
What is proportion?
Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole.
According to the problem,
Height of the flagpole = 9 feet
Length of the shadow = 6 feet
Length of the shadow cast by the tree = 14 feet
Let the height of the tree be x,
Since they cast aa shadow at the same time nearby, If we set up a proportion,
⇒ [tex]\frac{9}{6}[/tex] = [tex]\frac{x}{14}[/tex]
⇒ 6x = 126
⇒ x = [tex]\frac{126}{6}[/tex]
⇒ x = 21 feet
Hence, we can conclude, the height of the shadow is 21 feet.

Step-by-step explanation: Multiply everything by 7 to eliminate the fraction:
k+ 21 - 14k = -21
Isolate the variable:
k - 14k = -21-21
13k= -42
divide the sides by -13.

Explanation:
If you weighed 97.8 pounds on saturn as a decimal, you would take the whole number 97. Now you're left with the ".8" = ".80" this decimal would be 8/10. Now you put them together to create 97 and 8/10.

This week, 300 tickets were sold to the school play. This is 120 percent of the number of tickets sold last week. How many tickets were sold last week for the school play?
Answer:
300=120/100* number of tickets sold last week.
So last week's number of tickets=300÷(120/100)=300*100/120=30*100/12=5*100/2=5*50=250 tickets
So the answer is 250
A bowling alley charges a rental fee of $12 for the lane. They then charge $7.75 for each game bowled. If I have a total of $105. Write an inequality and solve it to find the maximum number of games, g, that I could play?
Answer:
12
Step-by-step explanation:
12 + 7.75*g <= 105 Subtract 12
7.75g < =105 - 12 divide by 7.75
g <= 93 / 7.75
g < = 12
You have to put an equal sign in there because 7.75 divides equally into 93.
