Answer:
87 deg
Step-by-step explanation:
Theorem:
Vertical angles are congruent.
If the angles are vertical angles, they are congruent.
Congruent angles have the same measure.
If <1 measures 87deg, then <2 also measures 87 deg.
Answer:
Step-by-step explanation:
Vertical angles are those opposite of each other where lines intersect. They are equal to each other. So the other angle is 87 as well.
In 1846 the depth of the river was 2.5 feet deep. In 1847 it rose 9%. This year, 1848, it dropped 6%. How deep is the river now?
Answer:
So the answer is 2.5615 feet.
Step-by-step explanation:
So the river is 2.5 feet deep, and when you find that 9% is, using the cross-multiplication formula to find the percent then 9% of 2.5 is 0.225, and when you add that to 2.5 you get 2.725, and when you find 6% of 2.725, you get 0.1635, and since it dropped, you subtract, and you end up with 2.5615
Hope I helped
The depth of the river in 1848 is 2.5615 feet.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The % formula is used to calculate a percentage of a whole in terms of 100. You may use this formula to express a number as a fraction of 100. If you look closely, calculating percentages indicated above can be readily computed using the formula below:
Percentage = (Value/Total Value) × 100
To solve this problem, we can start by finding the depth of the river in 1847 after it rose by 9%.
Depth in 1847 = 2.5 + (9% of 2.5)
Depth in 1847 = 2.5 + 0.225
Depth in 1847 = 2.725 feet
Next, we need to find the depth of the river in 1848 after it dropped by 6%.
Depth in 1848 = 2.725 - (6% of 2.725)
Depth in 1848 = 2.725 - 0.1635
Depth in 1848 = 2.5615 feet
Therefore, the depth of the river in 1848 is 2.5615 feet.

(-15,-6), (8,3) Find the slope of the line through each pair of points?
Slope is equal to the change in
y
over the change in
x
, or rise over run.
m = change in y / change in x
The change in
x
is equal to the difference in x-coordinates (also called run), and the change in
y
is equal to the difference in y-coordinates (also called rise).
m = y^2 - y^1 / x^2 x^1
Substitute in the values of

A hotel has a total of 172 rooms. About 58% of the hotel rooms have 2 queen beds in each room and the rest of the rooms have 1 king bed. How many rooms have queen beds?
Answer:
99.76 = 100
Step-by-step explanation:
Answer:
Queen rooms: 99.76 but since it is a real world problem round it to the nearest tenth
king rooms: 72
Step-by-step explanation:
172 x 58% or 172 x 0.58= 99.67.
rounded = 100.00
172 - 100 = 72
100= queen rooms
72= king rooms

Liam measured a line to be 12.9 inches long. If the actual length of the line is 11.3 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
>:(
Answer:
I think it may be 14.1593% or something around that. If not, forgive me.
Step-by-step explanation:
The percent error of the measurement, to the nearest tenth of a percent, will be 14.16%.
What is the error percentage?The amount of error is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Liam measured a line to be 12.9 inches long.
If the actual length of the line is 11.3 inches.
Then the percent error of the measurement, to the nearest tenth of a percent will be
[tex]\rm Error \ percentage = \dfrac{12.9 - 11.3}{11.3} \times 100\\\\Error \ percentage = 14.159 \approx 14.16\%[/tex]
