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.

A)40.3 revolutions
B)8.1 revolutions
C)19,876.2 revolutions
D)20.2 revolutions
Answer:
d
Step-by-step explanation:
1) convert ft to cm
5ft=152.4cm
633ft=19293.84cm
2) 2*3.14*152.4=975.072

The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.
1. The slope of the linear model is 1.5. What does this mean in terms of the maximum noise level and the number of people?
2. A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.
3. What is the -intercept of the linear model given? What does it mean in the context of the problem? Is this reasonable? Explain your reasoning.

Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...

12) Jennifer earns $78 per day working at a supermarket. She spends $8 each day at lunch and her gas to get to and from work is $6 per day. How much money will she earn in 28 days?
Answer:
$1792
Step-by-step explanation:
$78 x 28 = 2184
28 x $8 = 224
28 x $6 = 168
168 + 224 = 392
2184 - 392 = $1792
Check Work:
1792 + 392 = 2184
2184 / 78 or 2184 / 28
=78

Determine the measures of the unknown angles in the figure.
m < APD =
m < CPE =
m < BPD =
Answer:
angle APD=115 degrees
angle CPE=25 degrees
angle BPD=65 degrees
Step-by-step explanation:
APD=180-65=115 because it is supplementary
CPE=90-65=25 because it is complementary
BPD=65 because it is an alternate angle
The measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.
What is an angle?An angle is a geometrical shape that is formed by two rays or lines, called the sides or arms of the angle, that share a common endpoint, called the vertex of the angle.
Given is a figure, we need to find the measurement of the asked angles,
m ∠APD, m ∠CPE and m ∠BPD.
So,
∠APD + ∠APC = 180° [linear pair]
∠APD = 180° - 65°
∠APD = 115°
∠CPE + ∠CPA = 90° [complimentary angles]
∠CPE = 90° - ∠CPA
∠CPE = 90° - 65°
∠CPE = 25°
∠BPD = ∠APC [vertical angles]
∠BPD = 65°
Hence, the measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.

Step-by-step explanation:
Rotation, reflection, and translation are "rigid" motions that preserve congruence.
Dilation does not preserve congruence. Dilation multiplies the coordinates by a dilation factor, as in the transformation of choice A.
