1. Calculate the value of x in the following diagram. 53 - Y IN Q 5x 18
Answer:
x = 7
Step-by-step explanation:
QY = 5x
YZ = 18
QZ = 53
Thus:
QY + YZ = QZ (segment addition postulate)
5x + 18 = 53
5x = 53 - 18 (subtraction property of equality)
5x = 35
Divide both sides by 5
x = 7

A flagpole casts a 40-foot shadow. The angle of elevation from the tip of the
shadow to the tip of the flagpole is 34. How tall is the flagpole? Round your
answer to the nearest foot.
A. 29 feet
B. 22 feet
C. 27 feet
D. 33 feet
Answer:
27 Feet is the answer. Option C.
The flagpole is 27 feet tall.
What is right triangle?"It is a triangle whose one of the angle measures 90° "
What is tangent of angle?For angle [tex]\theta[/tex], [tex]tan(\theta)=\frac{opposite ~side~of~angle~\theta}{adjecent~side~of~angle~\theta}[/tex]
What is angle of elevation?"An angle that is formed between the horizontal line and the line of sight. "
For given question,
Consider the following diagram.
Here, AB = the flagpole,
A flagpole casts a 40-foot shadow.
so, BC = 40 foot
The angle of elevation from the tip of the shadow to the tip of the flagpole is 34°.
⇒ ∠ACB = 34°
We need to find the height of the flagpole.
We find the tan of angle 34°
[tex]\Rightarrow tan(34)=\frac{AB}{BC}\\\\ \Rightarrow 0.6745=\frac{AB}{40}\\\\\Rightarrow AB=0.6745\times 40\\\\\Rightarrow AB = 26.98\\\\\Rightarrow AB\approx 27~feet[/tex]
Therefore, the flagpole is 27 feet tall.

A hairdresser receives a discount on each comb purchased. The original price of each comb is x dollars. The hairdresser purchases 15 combs for a total of (15x-45) dollars. By how much is each comb discounted?
Answer:
$3
Step-by-step explanation:
Given that:
Price of each comb = $[tex]x[/tex]
15 combs were purchased in = $[tex](15x-45)[/tex]
To find:
Amount of discount offered on each comb.
Solution:
First of all, let us calculate the price of 15 combs at the price of $[tex]x[/tex] each.
Original Price of 15 combs = Price of one comb [tex]\times[/tex] Number of combs = $15[tex]x[/tex]
Now, there is some discount provided on the purchase of 15 combs.
Discount offered on 15 combs = Original price of 15 combs - Discounted price of 15 combs = [tex]15x- (15x-45)[/tex] = $45
Discount offered on each comb = Discount on 15 combs divided by 15
Discount offered on each comb = [tex]\frac{45}{15}[/tex] = $3

Which inequality represents the situation ten less than a number is a minimum of 30?
Answer:
x - 10 ≥ 30
Step-by-step explanation:
I'm 99.8% sure
It says 10 less than a number so that means subtract 10 from a number
Then it says minimum of 30 so that means the number has to be 30 or more so that's why I use the more than of equal to sign.

A jar has twenty-three coins consisting of dimes and nickels. The total amount of money is $1.90. How many dimes and nickels are there?
Answer:
8 nickels=.40
15 dimes=1.50
The number of dimes is 15 and the number of nickels is 8.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A container has 23 coins comprising dimes and nickels. The aggregate sum of cash is $1.90.
Let d be the number of dimes and n be the number of nickels. Then the equation is given as,
d + n = 23 ...1
0.1d + 0.05n = 1.90 ...2
From equations 1 and 2, then we have
0.1(23 - n) + 0.05n = 1.90
2.3 - 0.1n + 0.05n = 1.9
0.05n = 0.4
n = 8
Then the number of dimes is given as,
d + 8 = 23
d = 23 - 8
d = 15
The number of dimes is 15 and the number of nickels is 8.

20. A community is having a Taste of the Town event featuring dishes from the area’s best restaurants. The cost of admission is $25 in advance and $35 at the door. There are x people who pay in advance. A total or 530 tickets are sold. Which equation can be used to find the total amount, s, of money from ticket sales?
Answer:
18550 - 10x
Step-by-step explanation:
Given that :
Cost of admission in Advance = $25
Cost of admission at the door = $35
Number of people who paid in advance = x
Total number of tickets sold = 530
Total amount made from ticket sales will be :
(Number who paid in advance * cost) + (number who paid at the door * cost)
(25 * x) + (530 - x) * 35
25x + 18550 - 35x
18550 - 10x

Solve for x???????????
Answer:
x=11.7
Step-by-step explanation:
When every you have a straight line with a transversal, the line going through the straight line, the two angles will add up to 180.
180=10x+2+5x+3 ---> combine like terms
180=15x+5 ---> subtract 5 to the other side
175=15x ---> divide 15 to the other side
x=11.7
Ratios. Fill in the blank using the Word Bank. A recipe for one batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla. How many batches can you make with 15 cups of flour and 6 teaspoons of vanilla?
Answer:
3 batches of cookies
Step-by-step explanation:
Bank. A recipe for one batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla.
How many batches can you make with 15 cups of flour and 6 teaspoons of vanilla?
We can calculate the batches using either cups of flour or number of teaspoons.
For flour
5 cups of flour = 1 batch of cookies
15 cups of flour = x
Cross Multiply
5x = 15 × 1
x = 15/5
x = 3 batches of cookies
For teaspoons of vanilla
2 teaspoons of vanilla = 1 batch of cookies
6 teaspoons of vanilla = x
Cross Multiply
2x = 6 × 1
x = 6/2
x = 3 batches of cookies.
Hence: you can make 3 batches of cookies with 15 cups of flour and 6 teaspoons of vanilla
