Answer:
A) 9(2+7)
B) 3(12+9
C) 8(3+7)
D)4(5+8)
Step-by-step explanation:
A)
9*(x+7) = 18+63
9*(x+7) = 81
81/9 = x+7
9 = x+7
x = 2
B)
x*(12+9) = 36+27
x*(12+9) = 63
x*21 = 63
x = 63/21
x = 3
C)
8*(x+7) = 24+56
8*(x+7) = 80
x+7 = 80/8
x+7 = 10
x = 3
D)
x*(5+8) = 20+32
x*13 = 52
x = 52/13
x = 4

The angles will add up to 180*, but they also measure the same.
The angles in a triangle are in the ratio 1 : 2 : 3. Find the size of each angle in the triangle.
Answer:
30°,60°,90°
Step-by-step explanation:
All angles in a triangle added up make 180°. Add all numbers in the ratio and divide 180° by it. 180°÷6=30 so 1 in the ratio expression is equal to 30°. Because we know this, we can multiply each number in the ratio by 30° to get the answer above
Solve for the value of a.
Answer:
7 will be the answer.
Step-by-step explanation:
The angles are complementary angles i.e their sum is 90°.
(5a+3)°+52°=90°
5a+55°=90°
5a=90°-55°
5a=35°
a=35°/5
a=7
Now assume a 95% confidence level. Without performing any calculations, complete the sentence below. The margin of error for a 95% confidence level will be
Answer: greater than 0.3
Step-by-step explanation:
On edge
The margin of error for a 95% confidence level will be greater than 0.3.
What is a confidence interval?A random population parameter is likely to be included in a confidence interval, which is a range of values that is limited by the statistic's mean. The confidence level is the percentage of probability, or certainty, that, after repeated random sample draws, the confidence interval would include the true population parameter.
Given:
A confidence level is 95%.
The formula to calculate the margin of error:
The margin of error = Z x S/√n.
Where S is the standard deviation and n is the sample size.
The corresponding z-score of the confidence level is 95%.
So, the margin of error will be always greater than 0.3.
Therefore, the margin of error will be always greater than 0.3.

Maria is 4 ft 2in tall. To find the height of a flagpole, she measured her shadow and the pole's shadow . What is the height h of the flagpole?
Answer:
25 ft
Step-by-step explanation:
The height of the flagpole, using trigonometric ratio is 25feet.
The tangent of angle C will be the ratio of Maria's height to her shadow.
What is the tangent of an angle?The tangent of an angle is the ratio of opposite side to the adjacent side.
It is given that,
Her height = 4 ft 2 inch = 25/6 feet
Length of her shadow =10/3 feet
So, tan C = (25/6)/(10/3)
tan C = 5/4
We know that ∠C and ∠T will be equal
So, tan C = tan T = h/20
5/4 = h/20
h =25
Therefore, The height of the flagpole, using is 25feet.

Answer:
135
Step-by-step explanation:
The prism is 9/4 cm = 9×(1/4 cm) = 9 cubes wide.
The prism is 3/4 cm = 3×(1/4 cm) = 3 cubes deep.
The prism is 5/4 cm = 5×(1/4 cm) = 5 cubes high.

AUTHORITY ? description In your own words .this phrase has probably done more damage to investors than just about any other in all of market history.
Answer:
Authority is the accepted power of a person or an organization to lead another person or group. In a political sense, authority also stands for the power and dominion over an area or country held by the government. Authority legitimized by law or government is called 'competent authority'. A person who is generally respected by knowledge or status in a certain area is 'authoritative' in that area.
Authority regulates the relationships between people in society. If authority is absent, anarchy reigns. The difference between authority and power is that authority is legitimate. It has the right to exercise this power by, for example, imposing sanctions.

In triangle FGH shown below, what is the measure of < F degrees?
Record your answer and fill in the bubbles on your answer document. Be sure to use
the correct place value.
Answer:
∠F = 19.5°
Step-by-step explanation:
The sum of all of the angles in a triangle is 180°
∠F + ∠H + ∠G = 180°
∠F + 127° + 33.5° = 180°
∠F + 160.5° = 180°
-160.5° -160.5°
∠F = 19.5°
