9. A triangle has an area of 36 yd2 and a base of 3 yd, what is the height of the triangle?
Answer:
24yards
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 24 \ yards}}[/tex]
Step-by-step explanation:
The formula for a triangle's area is:
[tex]a= \frac{1}{2} bh[/tex]
We know the area is 36 square yards and the base is 3 yards.
[tex]a= 36 \ yd^2 \\b= 3 \ yd[/tex]
Substitute the values into the formula.
[tex]36 \ yd^2 = \frac{1}{2} (3 \ yd )h[/tex]
Divide by 1/2 or multiply both sides by 2.
[tex]2 * 36 \ yd^2 = \frac{1}{2} (3 \ yd )h *2[/tex]
[tex]72 \ yd^2= (3 \ yd)h[/tex]
We are trying to solve for the height, so we must isolate that variable. h is being multiplied by 3. The inverse of multiplication is division, so we must divide both sides by 3 yd.
[tex]\frac {72 \ yd^2}{3 \ yd}= \frac{(3 yd) h}{3 \ yd}[/tex]
[tex]24 \ yd =h[/tex]
The height of the triangle is 24 yards.
d^2 + 2d - 8 = 0
explain plz
Answer:
d^2 +2d-8=0
first pick two numbers which add up to make +2 and by multiplying those two numbers they should be able to create -8.
so for example 4 and 2
4-2=2
4 x -2= -8
so now factorise:
d^2 +2d-8=0
d^2+4d-2d -8=0
d(d+4)-2(d+4)=0
d+4=0 d-2=0
d=-4 d=2

Find the surface area of the
rectangular prism.
3 cm
10 cm
7 cm
[?] sq cm
Answer:
Step-by-step explanation:
There are six faces on the prism:
Two faces are 7 cm by 10 cm, area = 7×10 = 70 cm² each
Two faces are 7 cm by 3 cm, area = 7×3 = 21 cm² each
Two faces are 10 cm by 3 cm, area = 10×3 = 30 cm² each
surface area = 2(70) + 2(21) + 2(30) = 140 + 42 + 60 = 242 cm²
Convert y = 3(x - 2)2 - 10 to STANDARD form.

Answer:
x = 28
m∠ACD = 68°
Step-by-step explanation:
∠BAE ≅∠DAC because they are vertical angles
∠ACD = 180 - 124 = 56°
to find 'x': 56 + 2x + (180 - 4x) = 180
236 - 2x = 180
-2x = -56
x = 28
m∠ACD = 180 - 4(28) = 180 - 112 = 68°

In 2019, Chris made $142,000 as a dentist. Social Security tax was 6.2% to a maximum income of $132,900.
Medicare tax was 1.45% of all income. How much did Chris pay in FICA Taxes?
Type your answer
Answer: $10,298.80
Step-by-step explanation:
Chris made more than the limit required for the Social Security tax so his Social Security tax will be based on the maximum amount of $132,900.
His Social Security tax is therefore:
= 6.2% * 132,900
= $8,239.80
There are no limits for Medicare so Chris will pay taxes on the whole amount he earned of $ 142,000.
Medicare = 1.45% * 142,000
= $2,059
FICA tax = Social security + Medicare
= 8,239.80 + 2,059
= $10,298.80

Answer:
[tex] \huge \: x = 7 {0}^{o} \\ \: \huge \: y = 3 {0}^{o} \\ \huge z = {20}^{o} [/tex]Step-by-step explanation:
to understand thisyou need to know about:trianglesequationPEMDAStips and formulas:a straight line contains 180°a triangle contains 180°let's solve:equation for x
according to the question
110°+x=180°
x=180°-110°
x=70°
equation for y
according to the question
[tex]11 {0}^{o} + {40}^{o} + y = 18 {0}^{o} [/tex]
[tex]15 {0}^{o} + y = 180^{o} [/tex]
[tex]y = 18 {0}^{o} - 15 {0}^{o} [/tex]
[tex]y = 3 {0}^{o} [/tex]
equation for z
according to the question
90°+x+z=180°
90°+70°+z=180° (since x=70°)
160°+z=180°
z=180°-160°
z=20°
Answer:
X= 70
Z= 20
y= 30°
Step-by-step explanation:
Finding X:
Sum of angle in a straight line is 180
Therefore X = 180-110
Finding z:
Sum of angle in triangle is 180, and it’s a right angled triangle (90°)
Z= 180-(x+90)
Z= 180-( 70+90)
Finding y, look at the big triangle ABC:
There’s a right angle and <C is 40°,
Therefore <B is 180-(40+90)= 50°
<B= y + z
50° = 20° + y
y= 30°

Emma is a sales clerk at a bicycle shop. She is paid $6.25 per hour for 30 hours work week plus a commission of 8% of sales. In one week, her sales were $2319.75, what is her gross weekly earning?
Answer: $373.08
Step-by-step explanation:
First find out what she earned from her normal wages.
She is paid $6.25 per hour for 30 hours in a week. Her weekly pay is therefore:
= 6.25 * 30
= $187.50
She then gets 8% of her sales as commission. Her commission is therfore:
= 8% * 2,319.75
= $185.58
Her gross pay is therefore:
= Weekly pay + Commission
= 187.50 + 185.58
= $373.08

Three-quarters of a pound of candy cost 66 cents. Find the cost of one pound
of candy.
Answer:
$0.88 per pound
Step-by-step explanation:
you want to divide the 3/4 pounds by 3, and when you do that, you also have to divide the 66 cents by 3 as well, then multiply the 1/4 you get from dividing 3/4 by 3, and multiply it by 4 to get 1 pound, but when you do that, you have to do the same thing with the 22 cents you get from dividing 66 cents by 3, which will give you 88 cents per pound

Answer:
Part 1: G)52% H)28% I)19% J)75% K)95%
Part 2: 88%
Step-by-step explanation: I did math stuff lol, converted the decimal into a percent
Ex: 13/25= 0.52
0.52= 52%
Answer:
g. 52%
h. 28%
i. 19%
j. 75%
k. 95%
l. 88%
Step-by-step explanation:
g. 13/25
The denominator is currently 25. We must multiply it by 4 to reach 100. By converting the denominator to 100, the numerator will give us the answer to the percentage. However, when multiplying one side of the fraction (the denominator), we must also do the same to the other side of the fraction (the numerator).
Hence:
13 × 4 / 25 × 4
52/100
Since the denominator is 100, we can confidently say the answer is 52%
h. 7/25
Multiply by the numerator and the denominator by 4 so that the denominator equals 100.
7 × 4 / 25 × 4
28/100
28%
i. 19/100
The denominator for this fraction is 100, meaning the percentage is the numerator:
19%
j. 3/4
To get from 4 to 100, we must multiply by 25. What we do to the denominator, we must do to the numerator.
3 × 25 / 4 × 25
75/100
75%
k. 19/20
In order to change the denoninator to 100, multiply the denominator by 5 (20 × 5 = 100). Multiply by 5 to the numerator too to get the percentage.
19 × 5 / 20 × 5
95/100
95%
l. Out of 25 questions, Maria answered 22 correctly. If we write this as a fraction, we would put the total number (of questions) as the denominator with the correctly answered (number of questions) as the numerator:
22/25
We have to convert the denominator to read as 100 instead of 25. To do so, we must multiply 25 by 4. Whatever we do to the denominator, we must do to the numerator which means multiply the numerator by 4 as well.
22 × 4 / 25 × 4
88/100
88%
find the value of x in the diagram below
Answer:
x = 12
Step-by-step explanation:
ZY is a midsegment and is half the measure of SQ, that is
x + 2 = [tex]\frac{1}{2}[/tex] (3x - 8) ← multiply through by 2 to clear the fraction
2x + 4 = 3x - 8 ( subtract 2x from both sides )
4 = x - 8 ( add 8 to both sides )
12 = x
