Answer:
the answer will be: 16
Step-by-step explanation:
Why? Because =
20-5y+2x
20 - 5 • 4 + 2 • 8 =
(5 • 4 = 20)
(2 • 8 = 16)
20 - 20 + 16 =
(20 + 16 = 36)
20 - 36 = 16

Answer:
A
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
1. P(E)>P(D) (Event E is more likely to occur, therefore it has a greater probability)
2. P(E)>0.5 (The probability of event D is given as 0.5, so rewrite P(D) in the inequality)
3. 0.5 is equal to 0.5 and 0.1 is less than 0.5, so you can rule out options A and D
4. This leaves us with options 1.5 and 0.9, but it is impossible to have a probability that is greater than equal to one, so you can immediately rule out B
5. After this elimination process, the only remaining answer is C) P(E)=0.9

A highway sign shows a speed limit of 60 miles per hour. Which of the following car speed measurements represent the same level of accuracy compared to the speed limit sign? Check all that apply. A. 64 mph B. 56 mph O C. 48 mph O D. 68 mph
Answer:
B and C
Step-by-step explanation:
IT is found that B. 56 mph and C. 48 mph car speed measurements represent the same level of accuracy compared to the speed limit sign.
What is speed?Speed can be calculated as the ratio of distance traveled to the time taken
We can see that As the speed limit on the highway is 60 miles per hour and the speeds mentioned above are below the speed limit.
The legal top speed at which a vehicle may travel on a specific section of road is determined by speed limits for road traffic, since they are utilized in the most of countries.
On a traffic sign, it is known that the maximum allowed speed is typically displayed and expressed in kilometers per hour (km/h) or miles per hour (mph).

Ellie wanted to build a fence around her rectangular garden. The garden is 10 ft by 20 ft. A) What is the perimeter of the garden in feet?
Answer:
60 feet
Step-by-step explanation:
Perimeter is the sum of the four sides of a rectangle
the formula for the perimeter of a rectangle = 2 x (length + breadth)
2 x (10 + 20)
2 x (30)
= 60 feet
Alternatively, you can add the sides together : 10 + 10 + 20 + 20 = 60 feet
Solve for k 9k^3=1125

Simplify using properties of operations and then factor the expressions using the GCF. (2g + 2) - (-4g - 7)
Answer:
3(2g + 3)
Step-by-step explanation:
We start out with the expression (2g + 2) - (-4g - 7).
Firstly, let's distribute the negative:
(2g + 2) - (-4g - 7)
2g + 2 + 4g + 7
Now, combine like terms:
2g + 4g + 7 + 2
6g + 9
The GCF stands for "Greatest Common Factor." In this case, we have to find the GCF between 6 and 9. What is the GCF of 6 and 9? It would be 3. So,
6g + 9
3(2g + 3)

150*(1 - 5/8) = 150(3/8) = 56.25Option A#2
56.80 + 22.70x = 374.6022.7x = 374.60 - 56.8022.7x = 317.8x = 317.8/22.7x = 14 months#3

5 Gretchen borrowed $50 from her parents for 3 months. They charged her 14% interest. How much does she need to pay her parents to pay off the loan?
Step-by-step explanation:
simple interest = principal×rate×time
S.I = $50×(14÷100)×3
S.I=$50×0.14×3
S.I=$21
Amount= principal + simple interest
Amount = $50+$21
Amount = $71

At work, Mr. Grinnell receives 20 phone calls every 60 minutes. How many calls should he expect to receive in 180 minutes?
60
80
100
40
Answer:
Use a ratio.
20/60 = x/180
180/60 = 3, so 20*3 is 60.
The answer is 60.
Answer:
60
Step-by-step explanation:
Find out how many phone calls Mr. Grinnell receives in 1 minute.
60 mins = 20
1 min = 20 ÷ 60 = 0.333
180 mins = 0.333 x 180 = 59.94
59.94 rounded to the nearest whole number = 60

Find the average value fave of the function f on the given interval. f() = 5 sec2(/6), 0, 3 2
Answer:
[tex]f_{ave}[/tex] = [tex]{\frac{10 }{3\pi }[/tex]
Step-by-step explanation:
To find - Find the average value fave of the function f on the given interval. f(x) = 5 sec²(x/6), [0, 3[tex]\pi[/tex]/2]
Proof -
We know that,
Average value of f in the interval [a, b] is -
[tex]f_{ave}[/tex] = [tex]\frac{1}{b - a}\int\limits^b_a {f(x)} \, dx[/tex]
Now,
Here a = 0, b = [tex]\frac{3\pi }{2}[/tex], f(x) = [tex]5sec^{2}(\frac{x}{6} )[/tex]
Now,
[tex]f_{ave}[/tex] = [tex]\frac{1}{\frac{3\pi }{2} - 0}\int\limits^{\frac{3\pi }{2} }_0 {5sec^2 ({\frac{x}{6} }) } \, dx[/tex]
= [tex]{\frac{2 }{3\pi }}\int\limits^{\frac{3\pi }{2} }_0 {5sec^2 ({\frac{x}{6} }) } \, dx[/tex]
= [tex]{\frac{10 }{3\pi }}\int\limits^{\frac{3\pi }{2} }_0 {sec^2 ({\frac{x}{6} }) } \, dx[/tex]
= [tex]{\frac{10 }{3\pi }}[\ {tan({\frac{x}{6} }) }|^{\frac{3\pi }{2} }_0 \, ][/tex]
= [tex]{\frac{10 }{3\pi }}[\ {tan({\frac{x}{6} }) - tan({0) } \, ][/tex]
= [tex]{\frac{10 }{3\pi }}[ {1 - 0 } ][/tex]
= [tex]{\frac{10 }{3\pi }[/tex]
⇒[tex]f_{ave}[/tex] = [tex]{\frac{10 }{3\pi }[/tex]
Sabrina has a rectangular swimming pool in her backyard. She fills it with water to the depth of 4 feet. The water in the pool has a volume of 1600 cubic feet. What are the possible dimensions of the swimming pool with the given depth? Select ALL that apply. WHAT IS THE ANSWER????? PRETTY PLS AND THANK YOU
Answer: [tex]20\times 20, 16\times 25, 10\times 40[/tex]
Step-by-step explanation:
Given
The volume of the pool is [tex]1600\ ft^3[/tex]
Depth of water is [tex]d=4\ ft[/tex]
Suppose A is the base of the pool
[tex]\Rightarrow V=A\times d\\\Rightarrow 1600=A\times 4\\\Rightarrow A=400\ ft^2[/tex]
This area can be written as
[tex]\Rightarrow A=10\ ft\times 40\ ft\ or\\\Rightarrow A=16\ ft\times 25\ ft\ or\\\Rightarrow A=20\ ft\times 20\ ft[/tex]
