Truman's father is designing a toy car ramp for him. His dad determined that the measure of angle x needs to be increased by 20
What is the measure of the new angle?
Answer:
20°
Step-by-step explanation:
Solution,
Here,
→(x+20°)+160°=180°[Sum of a straight line is 180°]
→x=180°-180°
→x=0°
Again,
→x+20°
→0°+20°
→20°

Suppose the commute times for employees of a large company follow a
normal distribution. If the mean time is 18 minutes and the standard
deviation is 5 minutes, 95% of the employees will have a travel time within
which range?
A. 13.25 minutes to 22.75 minutes
B. 8 minutes to 28 minutes
Using the Empirical Rule, it is found that 95% of the employees will have a travel time within the following range:
B. 8 minutes to 28 minutes.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.Considering that the mean time is 18 minutes and the standard deviation is 5 minutes, the the bounds of the 95% range are given by:
18 - 2 x 5 = 8 minutes.18 + 2 x 5 = 28 minutes.Hence option B is correct.

Jesse earns 9 each time he washes a car. He wants to buy a game that costs 30 How many cars does, Jesse need to wash to earn enough money to buy the game?
Answer:
Jesse would need to wash four cars.
Step-by-step explanation:
9 times 4 is 36, so Jesse would need to wash 4 cars, and if he washed only 3 cars, you would do 9 times 3 which would get you to 27, which is too little for the game he wishes to buy.

Find the volume of a cylinder if it has a diameter of 8 and a height of 12. Leave your answer in terms of pi
A) 64 pi
B)192 pi
C) 256 pi
D)768 pi
Answer:
B) 192 pi
Step-by-step explanation:
The volume of a cylinder is found from the formula ...
V = πr²h
where the radius is r and the height is h. The radius is half the diameter.
__
V = π(8/2)²(12) = 192π . . . . . . using the given values

Solve the following triangle.
Dont answer if you dont know the answer or report answer it wrong get an report
Step-by-step explanation:
2 things to remember :
1. the sum of all angles in a triangle is always 180°.
2. the law of sine
a/sin(A) = b/sin(B) = c/sin(C)
triangle 1 :
angle B = 180 - 62.2 - 43.8 = 74°.
a/sin(62.2) = 15.8/sin(74)
a = 15.8 × sin(62.2)/sin(74) = 14.53961961... in
c/sin(43.8) = 15.8/sin(74)
c = 15.8 × sin(43.8)/sin(74) = 11.37657122... in
triangle 2 :
14.9/sin(49) = 11.6/sin(A)
sin(A) = 11.6 × sin(49)/14.9 = 0.587559136...
angle A = 35.98398776...° ≈ 36°
angle C = 180 - 49 - 35.98398776... = 95.01601224...° ≈
≈ 95°
c/sin(95) = 14.9/sin(49)
c = 14.9 × sin(95)/sin(49) = 19.66708505...
newly weds triangle :
let's call the 2 sides a and b (25 m and 30 m).
the angle between them is 60°.
here we should use the extended Pythagoras for general triangles :
c² = a² + b² - 2×a×b×cos(C)
with c being the side opposite to the angle C.
so, we have in our case
c² = 25² + 30² - 2×25×30×cos(60) = 625 + 900 - 750 =
= 775
c = sqrt(775) = sqrt(25×31) = 5×sqrt(31) = 27.83882181... m
the area of the triangle we get via Heron's formula :
s = (a+b+c)/2 = (25+30+c)/2 = 41.41941091...
area = sqrt(s(s-a)(s-b)(s-c)) = sqrt(s(s-25)(s-30)(s-c)) =
= sqrt(105,468.75) = 324.7595264... m²
with Php 2000 per m² this would cost

And his daughter is presently 5 years old.
Therefore, the father is 5 times older than his so. Currently.
In 5 years, the father will be 30 years old and the son will be 10 years old. So the father will be 3 times the daughters age.

Jada fills the bathtub before taking a bath and then allows the water to drain when she is done. The graph below models the number of gallons of water, y, in the bathtub over time, t, in minutes.
On a graph, the graph increases, remains constant, and then decreases.
Is the number of gallons of water in the bathtub a function of time?
Yes because each t value is paired with exactly one number of gallons.
Yes because the number of gallons is bounded between y = 0 and y = 36.
No because each number of gallons is paired with more than one t value.
No because from t = 5 to t = 20 the number of gallons of water is constant.
Answer:
A, Yes because each t value is paired with exactly one number of gallons.

Step-by-step explanation:
There are 10 mm in 1 cm, so to find how many mm the measurements are, multiply the measurement in cm by 10.
a) 0.7 cm
0.7 cm x 10 mm per cm = 7 mm
b) 1.8 cm
1.8 cm x 10 mm per cm = 18 mm
c) 4.9 cm
4.9 cm x 10 mm per cm = 49 mm

HELP for (ii)…..how do we find a?
By using the information given on the graph, we can see that a = 3.
How to find the value of a?
Here we have an exponential of the form:
[tex]y = p*a^x[/tex]
And by looking at the graph, it passes through (0, 4) and (2, 36), so we can write:
[tex]4 = p*a^0\\\\36 = p*a^2[/tex]
From the first equation we get that p = 4, replacing that on the second one we get:
[tex]36 = 4*a^2\\\\36/4 = 9 = a^2\\\\\sqrt{9} = 3 = a[/tex]
So we conclude that a = 3.

If the triangle ABC is enlarged using the point P as a center, then the point of the dilated triangle will be A'(-3, 2), B'(1, 2), and C'(-1, -2).
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
The coordinate of point P will be (5, 4).
Let shift the origin at P, then the coordinate of ABC will be
A(-4, -1), B(-2, -1), and C(-3, -3)
If the scale factor is 2. Then the coordinate of the triangle A'B'C' will be
A'(-8, -2), B'(-4, -2), and C'(-6, -6)
Then shift the origin at (0, 0), then the coordinate of A'B'C' will be

Answers:

============================================================
Explanation:
There are 8 pizza slices shaded out of 12 total.
One fraction we can form is 8/12
Divide each part by the GCF 4
8/4 = 212/4 = 3This means 8/12 is the same as 2/3
Check out the image below to see how 8/12 and 2/3 are the same. Refer to figure 1. We have 2 slices shaded out of 3 total.
Then check out figure 2 to see how 2/3 and 4/6 are the same. By extension, this means that 8/12 and 4/6 are the same. Figure 2 shows 4 shaded slices out of 6 total.
There are infinitely many ways we can split up this pie, so there are infinitely many fractions to write as the answers.
