Answer:
X = 10.7
Step-by-step explanation:
25^2 - 16^2 = 369 which squared is approximately 19.2. We need X which is the smaller side so we minus 22^2 from 19.2^2 which is 115.36 which is squared to 10.7
what is the volume of this shape?
Answer:
84,000 cm³
Step-by-step explanation:
This is a prism with a trapezoidal base.
V = BH
where V = volume of prism, B = area of the base, H = height of the prism
For the trapezoid, the area is
A = ½(b1 + b2)h,
where A = area, b1 and b2 are the bases, and h is the height of the trapezoid.
V = ½(b1 + b2)hH
V = ½(60 cm + 45 cm) (20 cm)(80 cm)
V = 84,000 cm³

Step-by-step explanation:
The axis of symmetry of quadratic ax²+bx+c is x=-b/(2a). For the given equation, the axis of symmetry is ...
x = -4/(2(3/2)) = -4/3
The only graph with its vertex at x=-4/3 is graph A.
_____
Additional comment
You can also make the correct choice by evaluating the equation at a couple of different values of x. Convenient ones are x= -1, or 0, or +1. The value at x=0 is the y-intercept, (0, -2), which seems to be a point on all of the graphs. The value at x=1 is 3/2+4-2 = 3.5, which looks like it is only seen on graph A.

The function f(x) = 9x +5 is one-to-one.
Find an equation for f-'(x), the inverse function.
Answer:
The inverse function is [tex]f^{-1}(x) = \frac{x - 5}{9}[/tex]
Step-by-step explanation:
Inverse function:
Suppose we have a one-to-one function y = f(x). To find it's inverse, we exchange y and x, and then isolate y.
In this question:
[tex]y = 9x + 5[/tex]
Exchanging x and y:
[tex]x = 9y + 5[/tex]
Isolating y:
[tex]9y = x - 5[/tex]
[tex]y = \frac{x - 5}{9}[/tex]
[tex]f^{-1}(x) = \frac{x - 5}{9}[/tex]
The inverse function is [tex]f^{-1}(x) = \frac{x - 5}{9}[/tex]

Find the mean ,median and mode of the weights of people shown
Answer:
[tex](a)\ Mean = 80kg[/tex]
[tex](b)\ Median = 76kg[/tex]
[tex](c)\ Mode = 61kg[/tex]
Step-by-step explanation:
Given
[tex]Data:105kg, 53kg ,76kg ,91kg ,120kg ,61kg ,55kg ,98kg ,61kg[/tex]
[tex]n = 9[/tex]
Solving (a): The mean
This is calculated using:
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{105kg+53kg +76kg +91kg +120kg +61kg +55kg +98kg +61kg}{9}[/tex]
[tex]\bar x = \frac{720kg}{9}[/tex]
[tex]\bar x = 80kg[/tex]
Hence:
[tex]Mean = 80kg[/tex]
Solving (b): The median
[tex]Data:105kg, 53kg ,76kg ,91kg ,120kg ,61kg ,55kg ,98kg ,61kg[/tex]
Arrange in ascending order
[tex]Data: 53kg ,55kg, 61kg ,61kg,76kg ,91kg ,98kg , 105kg,120kg[/tex]
[tex]n = 9[/tex]
So, the position of the median element is:
[tex]Median = \frac{n+1}{2}th[/tex]
[tex]Median = \frac{9+1}{2}th[/tex]
[tex]Median = \frac{10}{2}th[/tex]
[tex]Median = 5th[/tex]
The 5th element is 76kg
Hence:
[tex]Median = 76kg[/tex]
Solving (c): The mode
In the given data
[tex]Mode = 61kg[/tex]

Abby scored 87, 93, 96, and 89 on her first four history quizzes. What score does
Abby need to get on her fifth quiz to have an average of exactly 91 on her history
quizzes?
Answer:
73
Explanation
To find the average we need to find the mean. So you have
87,93,96, and 89. Add it up and you get 365. Next you have to divide it by how many numbers there are, so 365 divided by 5 and you get 73.
(I divided 365 by 5 because we are looking for the score she needs on the 5th quiz too.)

Step-by-step explanation:
the sum of three consecutive even numbers is 42. what are the three numbers?
Answer:
12, 14, and 16
Step-by-step explanation:
Assume
1st number: x
2nd number: x+2
3rd number: x+4
(I'm adding 2 for each number because even numbers skip by 2)
The numbers add to 42, so
x+(x+2)+(x+4)=42
x+x+2+x+4=42
3x+6=42
3x=36
x=12
1st number: 12
2nd number: 12+2=14
3rd number: 12+4=16

0 0.15
0.30
0 0.50
Answer:
C, 0.30
Step-by-step explanation:
First, simplify.
[tex]\frac{15}{50}[/tex] = [tex]\frac{3}{10}[/tex]
Next, divide
3 ÷ 10 = 0.30 or 0.3
Have a great day!
Answer:
0.30 is the probability that a car arriving at this intersection will not fully stop.Step-by-step explanation:
Given that:
Total number of cars passing = 50 cars Number of cars not fully stop at the stop sign = 15 carsTo Find:
What is the probability that a car arriving at this intersection will not fully stop?We know that:
P(E) = F/TWhere,
P(E) = Probability of an event F = Favorable outcomes = 15T = Total outcomes = 50Finding the probability that a car arriving at this intersection will not fully stop:
⟶ P(E) = 15/50
Multiply by 2 with both numerator and denominator.
⟶ P(E) = (15 × 2)/(50 × 2)
⟶ P(E) = 30/100
⟶ P(E) = 0.30
Hence,
The probability that a car arriving at this intersection will not fully stop is 0.30.I need this please help me

Tarinda's corn plant was 7- 1/3 inches tall at the end of Week 1. The corn plant was 18 1/2 inches tall at the end of Week 2. How many inches did the corn plant grow during Week 2?
Answer:
The corn plant grew by 11.17 inches during week 2.
Step-by-step explanation:
7 and 1/3 inches tall at the end of Week 1.
The height at the end of week 1, as a simple fraction, is:
[tex]7 + \frac{1}{3} = \frac{3*7 + 1}{3} = \frac{22}{3}[/tex]
The corn plant was 18 1/2 inches tall at the end of Week 2.
At the end of week 2, the height will be of:
[tex]18 + \frac{1}{2} = \frac{18*2+1}{2} = \frac{37}{2}[/tex]
How many inches did the corn plant grow during Week 2?
Height at the end of week 2 subtracted by the height at the end of week 1. So
[tex]\frac{37}{2} - \frac{22}{3} = \frac{3*37-2*22}{6} = \frac{67}{6} = 11.17[/tex]
The corn plant grew by 11.17 inches during week 2.

A cylinder has a height of 6 meters and a diameter that is 6 times the measure of the height. Using 3.14 for pi, which of the following can be
used to calculate the volume of the cylinder? (6 points)
Answer:
The volume of the cylinder is 6,104.16 square meters.
Step-by-step explanation:
Given that a cylinder has a height of 6 meters and a diameter that is 6 times the measure of the height, to determine, using 3.14 for pi, which of the following can be used to calculate the volume of the cylinder, the following calculation must be done, knowing that the volume of a cylinder is determined by multiplying Pi by the height by the radius squared, and that the diameter of a circle is twice its radius:
3.14 x 6 x (6x3) ^ 2 = X
18.84 x 18 ^ 2 = X
18.84 x 324 = X
6,104.16 = X
Therefore, the volume of the cylinder is 6,104.16 square meters.

9514 1404 393
Answer:
ΔLMN ~ ΔLFG; scale factor 7/3
Step-by-step explanation:
The ratios of side lengths, shortest to longest are ...
FG : GL : LF = 24 : 36 : 42 = 4 : 6 : 7 (reduced)
MN : NL : LM = 56 : 84 : 98 = 4 : 6 : 7 (reduced)
The side ratios are the same, so ΔLMN ~ ΔLFG. The scale factor is ...
MN/FG = 56/24 = 7/3
