Answer:45
Step-by-step explanation:
This is the pythagorean theroem. So you would have sides a, b, and c, of the triangle.
[tex]a^{2}+b^{2}=c^{2} so\\c^{2}-b^{2}=a^{2} \\53^{2}-28^{2}=a^{2} \\a^{2}=2025\\a= \sqrt{2025} =45[/tex]
Answer:
The answer is 45
Step-by-step explanation:

Aubrey filled her pool 0.9 of the way with water. Water evaporated from the pool at a rate of 7.5ft ^ 3 per day.
Answer: hello your question lacks vital data hence I will provide you with a general equation within the scope of your question
answer :
General equation = ( Stiver and Mackay or EPA ) evaporation equations
E = [tex]\frac{PAW}{T +459.67}[/tex] or E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]
Step-by-step explanation:
Given data
volume of water in pool = 0.9 i.e. 90% full
rate of evaporation = 7.5ft^3 per day = 56.1039 gallons / day
Assumption :
Volume of pool = 16,000 gallons
In order to resolve the missing part of the problem apply the equation below
E = [tex]\frac{PAW}{T +459.67}[/tex] or E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]
where : E = Evaporation rate , P = water's vapor pressure , A = pool surface Area , W = wind speed , T = Temperature in Fahrenheit

what does n)-2 mean ??
The letter “n” notates “number” and refers to any number, similar to “x.” The little carat means they the number following, in this case a 2, is an exponent. So this can really be understood as “x squared.” Most likely, this term appeared in an equation.
find two fractions that have product of 2/5.
Answer:
2/7 and 7/5
Step-by-step explanation:
(2/7) times (7/5) results in the 14/35, which reduces to the desired 2/5.
The two desired fractions are 2/7 and 7/5.
A loaf of bread costs $0.90. Each loaf has 15 slices. How much does each slice of bread cost?
Answer:
Each slice of bread costs $0.06.
Step-by-step explanation:
To find how much each slice of bread costs, you need to divide the cost (0.90) by how many slices there are (15). When you divide the two, you get 0.06. To check your answer you can do 0.06x15 and that will equal $0.90.
Answer:
0.9/15=$0.06 per slice
Also what is this 1910 when did a loaf of bread cost 90 cents????

Answer:
x = 52
Step-by-step explanation:
An isosceles triangle is a triangle with two congruent sides, meaning two sides have the same measure. One property of an isosceles triangle is the base angles theorm. This theorem states that the angles opposite the congruent sides in an isosceles triangle are cognruent. Applying this theorem to the given triangle, one can state the following:
52 = x
Answer:
I think the answer is 52 so x=52
Please help guys!!!!!!!!!!!!!!
Answer:
a) x = -10
b) x = 7
Step-by-step explanation:
a)
2(x + 3) = x - 4
2x + 6 = x - 4
2x - x = -4 - 6
x = -10
b)
4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x - 18x = 6 + 8
2x = 14
x = 7

Tommy was solving the triangle below. Which of the following is TRUE about his solution? Help ASAP !!!!
Answer:
The value of x is incorrect he should be using 28/21 instead of 21/28
Step-by-step explanation:
tan = opp/adj
tanx = 28/21
The value of x is incorrect he should be using 28/21 instead of 21/28
Answer:
A) The value of x is incorrect. He should be using 28/21 instead of 21/28.
Step-by-step explanation:
Recall that [tex]tan\theta=\frac{opposite}{adjacent}[/tex]. This means that the correct setup would be [tex]tan\theta=\frac{28}{21}[/tex] since 28 is opposite of x° and 21 is adjacent to x°. Thus, your solution would be [tex]x^{o}=tan^{-1}(\frac{28}{21})=53.13010235^o\approx53.1^o[/tex]

Answer:
Choice C
Step-by-step explanation:
$80 to 5 hours
Divide both numbers by 5 to find the unit rate:
$16 to 1 hour, or 16 to 1
For x hours, the pay, y, is y = 16x.
Choice A is true.
Look at choice B.
When x = 5, y = 80.
This is correct because we are given that information.
The process is to multiply the hours by 16.
For x hours, y = 16x (from choice A)
For x = 7, y = 7 * 16
Choice B works.
Look at choice C.
We need a proportion. The left side is the ratio 80/5, meaning $80 for 5 hours of work. Notice that the first number in the ratio is dollars, and the second number is hours. Now we need another ratio written in the same order to set up a proportion. x dollars is to 7 hours. This is the ratio x/7. The correct proportion is
80/5 = x/7
Choice C is 80/5 = 7/x
Choice C is incorrect.
Look at choice D.
The graph shows that for 5 hours, the pay is $80, so by looking up x = 7, you can find the correct amount of pay.
Choice D works.
Answer: Choice C

Answer:
m∠6 = 110°
Step-by-step explanation:
∠6 and ∠8 are known as corresponding angles meaning they are equal to each other. Since m∠8 = 110°, m∠6 also equals 110°.
Answer:
11o degree
Step-by-step explanation:
angle 6 is 110 degree because the relation between angle 6 and angle 8 is that they are corresponding angles and corresponding angles are always equal.
An object is launched from the roof of a building 192
feet above the ground. The object's height (in feet)
after t seconds is given by the function
h(t) = -1672 +64t + 192
B) How many seconds does it take the object to hit the
ground?
Answer:
Unsure, sorry
Step-by-step explanation:
Answer:
t=6
Step-by-step explanation:
h(t) = -16t^2 +64t + 192
We want h(t) =0
0 = -16t^2 +64t + 192
Factor out -16
0 = -16 (t^2 -4t -12)
Factor. What terms multiply to -12 and add to -4 -6*2 = -12 -6+2 = -4
0 = -16(t-6)(t+2)
Using the zero product property
0=t+2 0=t-6
t = -2 t=6
But t=-2 happens before the event occurs so the solution is t=6
