Given ΔABC ≅ ΔDEF. Determine the measure of angle C.
A) 33 degrees
B) 55 degrees
C) 88 degrees
D) 92 degrees
Answer:
A) 33 degrees
Step-by-step explanation:
Since both triangles are congruent, the corresponding angles are congruent, as well. Angle C and Angle F are corresponding angles (meaning that they are the same angle on two different triangles), so their angle measures are congruent. Angle F is 33 degrees, so Angle C is 33 degrees.
Nathan usually drinks 37 ounces of water per day. He read that he should drink 62 ounces of water per day. If he starts drinking 62 ounces, what is the percent increase? Round to the nearest percent.
Answer:
68%
Step-by-step explanation:
The increase is (62 - 37), or 25, ounces. Comparing this to the original quantity (37 oz), we divide 25 oz. by 37 oz., obtaining 0.676 (a ratio). Multiplying this ratio by 100%, we get 68% (to the nearest percent).
The table shows the results of a survey of 100 people selected at random at an airport. Find the experimental probability that a person selected at random is going to City B.
The experimental probability that a person selected at random is going to City B is __
Answer:
3/50
Step-by-step explanation:
The experimental probability that a person selected at random is going to City B is 19/50.
What is the experimental probability?Experimental probability is a probability that is determined on the basis of a series of experiments.
The table shows the results of a survey of 100 people selected at random at an airport.
The total number of responses is;
= 24 + 38 + 14 +22 +2
= 100
The experimental probability that a person selected at random is going to City B is given by;
[tex]\rm Probability =\dfrac{Responses \ from \ city \ B}{Total \ responses}\\\\ Probability =\dfrac{38}{100}\\\\ Probability =\dfrac{19}{50}[/tex]
Hence, the experimental probability that a person selected at random is going to City B is 19/50.

The total of Jenny's 5 tests = 375
If she wants an average of 77 then
her 6 tests must total 6 x 77 = 462
462 - 375 = 87 which is what Jenny
must score on the sixth test for an
average of 77.
:-)
Answer:
79
Step-by-step explanation:
Sum of 4 test for Average of 82 must be 82 x 4 which is 328.
Subtract previous 3 scores from 328:
328 - (98 + 83 + 68)
328 - 249 = 79
She needs a 79
Figure B is a scale image of Figure A, as shown. Enter the scale factor applied to Figure A to produce Figure B: figure A, 3 2 4 and Figure B, 6 4 8
Answer:
1:2
Step-by-step explanation:
3x2=6

2. The volume of a cylinder varies jointly with its height and the square of the radius. A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. Another spice container is 3 inches tall with a radius of 1.5 inches, what would be the volume?
Answer:
Volume=21.195 cubic inch
Step-by-step explanation:
The volume of a cylinder varies jointly with its height and the square of the radius is expressed as
V∝hr^2
Introducing our constant of proportionality,K we have that
V =Khr^2
Given that A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. We have that
V =Khr^2
7.85=K 2.5 X 1^2
K=7.85/2.5 x1
K=3.14
Given that another spice container is 3 inches tall with a radius of 1.5 inches, Volume=?
V =Khr^2
V=3.14 X 3 X 1.5^2
V=21.195 cubic inch

A straight road to the top of a hill is 2500 feet long and makes an angle of 12 degrees with the horizontal. Find the height of the hill.
Answer:
519.8 feet
Step-by-step explanation:
A straight road to the top of a hill is 2500 feet long and makes an angle of 12 degrees with the horizontal. Find the height of the hill.
We solve this question using the Trigonometric function of Sine
sin theta = Opposite/ Hypotenuse
Theta = 12°
Hypotenuse = 2500 feet
Opposite = Height of the hill = x
Hence,
sin 12 = x/ 2500 feet
Cross Multiply
x = sin 12 × 2500 feet
x = 519.77922704 feet
Approximately = 519.8 feet
The height of the hill is 519.8 feet

Andy wants to buy a used car that cost $8,500. He has
saved $1,300 and can save an additional $225 each month.
How many months will it take for Andy to have enough
money for the car?
Answer:
32 months.
Step-by-step explanation:
Andy wants a car that costs $8,500.
He already saved $1,300.
$8500 - $1300 = $7200
Andy can save an additional $255 each month.
7200 ÷ 255 = 32
So, it would take Andy 32 months to have enough money to buy the car.

Use the figure to find the measures of the numbered angles. Need help ASAP please I’ll give you 15 points
Answer:
∠1 = 90°, ∠2 = 90°, ∠3 = 90°, ∠4 = 90°, ∠5 = 90°, ∠6 = 90°, ∠7 = 90°
Step-by-step explanation:
From the question, we have;
∠1 and the 90° are supplementary angles
∴ ∠1 = 180° - 90° = 90°
2) ∠2 is vertically opposite to the 90° angle, therefore;
∠2 = 90°
3) ∠3 is vertically opposite to ∠1 , therefore;
∠3 = 90°
4) ∠4 is the corresponding angle to the given 90° angle, therefore;
∠4 = 90°
5) ∠5 is the corresponding angle to ∠1, therefore;
∠5 = ∠1 = 90°
6) ∠6 and ∠2 are corresponding angles;
∴ ∠6 = ∠2 = 90°
7) ∠7 and ∠3 are corresponding angles;
∴ ∠7 = ∠7 = 90°

Veronika works as a cook at Toyem Catering, she makes $58,200/year. She pays 18% in taxes and $125/month for health insurance. What is Veronika's net income per month?
a
$4,200
b
$3,852
c
$4,850
d
$2,989
Veronika's net income per month is $3,852. Option B
How to calculate Veronika's net income per monthThe annual amount of taxes that Veronika pays:
Annual taxes = 0.18 x $58,200 = $10,476
Annual health insurance = $125/month x 12 months = $1,500
we can calculate Veronika's net annual income by subtracting the taxes and health insurance from her annual salary:
Net annual income = $58,200 - $10,476 - $1,500 = $46,224
We can calculate her net income per month by dividing her net annual income by 12:
Net monthly income = $46,224/12 = $3,852

Given this set of data: 132 127 106 140 158 135 129 138 What are the lower outlier limit and the upper outlier limit ? Answers separated by a comma and a space. Ex. 11, 179 * 1 point
Answer:
(111.5, 155.5)
Step-by-step explanation:
Given the data:
132 127 106 140 158 135 129 138
The Outlier formula :
Lower = Q1 - 1.5(IQR)
Higher = Q3 + 1.5(IQR)
Using a calculator :
Q1 = 128
Median, Q2 = 133.5
Q3 = 139
IQR = Q3 - Q1 = 139 - 128 = 11
Lower = Q1 - 1.5(IQR) = 128 - 1.5(11) = 111.5
Higher = Q3 + 1.5(IQR) = 139 + 1.5(11) = 155.5
