Answer:
308 minutes or 5 hours and 8 minutes
Step-by-step explanation:
First, let's add the bicycles of both boys and girls together:
6 + 8 = 14
Now, let's multiply that number by 22 since she will have to assemble all of those bicycles and it will take 22 minutes for each:
22 x 14 = 308
It will take a total of 308 minutes or 5 hours and 8 minutes to assemble all of those bicycles.

Given the function below, find f(-5).
f(x)= (x - 3)² +17
Answer:
81
Step-by-step explanation:
f ( x ) = ( x - 3 )² + 17
To find : f ( - 5 )
f ( - 5 ) = f ( x )
Here,
x = - 5
f ( - 5 ) = ( - 5 - 3 )² + 17
= ( - 8 )² + 17
= 64 + 17
f ( - 5 ) = 81

A spinner is divided into 6 equal sectors labeled with the letters A through F The spinner is spun 30 times. How many times is it expected that a vowel will be spun? O approximately 5 times O approximately 6 times approximately 10 times o approximately 15 times
The spinner illustrates probability, and it is expected that a vowel will be spun approximately 10 times
How to determine the expected number of vowels?In the spinner, we have:
Sections = 6
Vowels = 2 i.e. A and E
The expected number of vowels in 30 spins is:
Expected = Vowels/Sections * 30
This gives
Expected = 2/6* 30
Evaluate the product
Expected = 10
Hence, it is expected that a vowel will be spun approximately 10 times

Can someone please solve this problem for me. I'm kind of confused-
This is probability too-
Step-by-step explanation:
(1)The probability of landing on the color gray ONCE
= 2/7
Since it is spun 35 times, the expected number of times that it lands on a gray will be
(2/7 × 35) = 10 times
(2)The probability of landing on the color black ONCE
= 1/7
Since it is spun 105 times, the expected number of times that it lands on a black will be
(⅐ × 105) = 15 times
The formula is:
Expected value = (Number of spinning)×(probability of landing on a colour)

In a class of students, the following data table summarizes how many
students have a cat or a dog. What is the probability that a student
chosen randomly from the class has a dog?
Answer:
22/29
Step-by-step explanation:
First, add up all of the numbers given:
16 + 4 + 6 + 3 = 29
Now since there are 16 students who have a dog and a cat, and 6 who only have a dog, we add those numbers:
16 + 6 = 22
Now since there are 29 total numbers, that will be the number of outcomes out of the 22 people with dogs:
22/29

find the inverse of the function
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.
[tex]\stackrel{h(x)}{y}~~ = ~~6\sqrt[3]{2x+5}-1\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~6\sqrt[3]{2y+5}-1} \\\\\\ x+1=6\sqrt[3]{2y+5}\implies \cfrac{x+1}{6}=\sqrt[3]{2y+5}\implies \left( \cfrac{x+1}{6} \right)^3=\left( \sqrt[3]{2y+5} \right)^3[/tex]
[tex]\left( \cfrac{x+1}{6} \right)^3=2y+5\implies \left( \cfrac{x+1}{6} \right)^3-5=2y\implies \cfrac{\left( \frac{x+1}{6} \right)^3-5}{2}=y \\\\\\ \cfrac{\left( \frac{x+1}{6} \right)^3}{2}-\cfrac{5}{2}=y\implies \cfrac{~~ \frac{(x+1)^3}{6^3}~~}{2}-\cfrac{5}{2}=y\implies \cfrac{(x+1)^3}{432}-\cfrac{5}{2}=\stackrel{y}{h^{-1}(x)}[/tex]

Answer:
C)
Step-by-step explanation:
The first inequality, y ≥ 2x + 1 has no solution below the function since it is greater than OR EQUAL to it. Similarly, the second inequality, y > 1/2x - 1 has no solution at or below the function since it is only GREATER THAN this value.
If we look at the graph of these inequalities, we see that they don't overlap at all in quadrant IV. For that reason, this area of the graph there will have no solution, or empty set.

A traveler pulls a suitcase, as shown in the figure. (image below)
The force acting on the handle is 35 N at an angle of θ = 30°. How much work is done if the traveler moves 110 meters? Round to the nearest whole number.
1,893 Nm
1,925 Nm
2,703 Nm
3,334 Nm
Answer:
3334 N·m
Step-by-step explanation:
Work is the product of force and distance. The force used in the product is the force that is in the direction of motion.
__
The horizontal component of the applied force is ...
F = (35 N)cos(30°) ≈ 30.311 N
Then the work done is ...
W = Fd
W = (30.311 N)(110 m) = 3334 N·m

In parallelogram ABCD, m∠B = 32 + 35 and m∠D = 52 + 13. Find m∠C.
Answer:
113°
Step-by-step explanation:
1) according to the condition m(∠B)=m(∠D)=67°;
2) m(∠C)=180°-m(∠B)=180°-m(∠D);
m(∠C)=180-67=113°.
Which transformation is this an example of?
A. reflection
B. rotation
C. translation
D. None of these
Answer:
B. rotation
Step-by-step explanation:
A reflection would mean that the shape would be mirrored across the y-axis or the x-axis. A translation means that nothing about the shape changes except for the location. A dilation (not an answer option but still helpful to know) is the change in size of the shape. And finally, the correct answer for this problem, a rotation means that the shape is rotated at a specific point.
I included a picture that uses a shape to help explain this idea. I hope this helps! Have a lovely day!! :)

Using the distributive property to find the product (y−4x)(y2 4y 16) results in a polynomial of the form y3 4y2 ay−4xy2−axy−64x. what is the value of a in the polynomial? 4 8 16 32
The product (y−4x)(y^2 + 4y + 16) results in a polynomial of the form y3 4y2 ay−4xy2−axy−64x then the value of a is 16.
What is distributive property?The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is
A(B + C) = AB + AC
This property is known by distributive law and applies to subtraction also.
First let w = y-4x make distribution a bit easier
(y−4x)(y^2 + 4y + 16)
[tex]w(y^2 + 4y + 16)\\wy^2 + w4y + w16\\[/tex]
now put the values of w in the equation
[tex](y-4x)y^2 + (y-4x)4y + (y-4x)16\\y^3-4xy^2 + 4y^2-16xy+16y-64x\\[/tex]
