If the spinner is spun 40 times, predict the number of times the spinner would land on Section B
A. 11
B. 10
C. 5
D. 4

Answer:

C

Step-by-step explanation:

Usually rate is determined as a distance over time, where the time is a unit. In other words, we have "1" of the time (for example, 1 hour, 1 second, 1 gallon, etc).

Look at each answer choice:

A: doing 45 crunches in 1 minute

This is definitely a rate because the time (1 minute) is a unit.

B: paying $3.15 for 1 gallon of gas

Again, this is considered a rate because you're paying $3.15 per gallon.

C: folding 6 loads of laundry in 3 days

We can see this isn't a rate because the time is 3 days, not 1. So C is the answer.

D: walking 4 miles in 1 hour

This is a rate because our time is 1 hour.

The answer is C.

Answer:

C.folding 6 loads of laundry in 3 days

Step-by-step explanation:

folding 6 loads of laundry in 3 days means, 6/3 = 2 loads of laundry per day.

Rate is 2 per day

Answer:

The approximate surface area of the snowman's head is 125.33 sq.cm.

Step-by-step explanation:

Formula of surface area =[tex]4 \pi r^2[/tex]

We are given that The surface area of the base of the snowman is 1800 square centimetres

So,[tex]4 \pi r^2 =1800[/tex]

[tex]4 \times \frac{22}{7} \times r^2 = 1800 \\r^2 = \frac{1800 \times 7}{22 \times 4}\\r=\sqrt{\frac{1800 \times 7}{22 \times 4}}\\r=11.96[/tex]

The radius of a the head of a snowman is about 2/3 times the radius of the base of the snowman

So, Radius of head = [tex]\frac{2}{3} \times 11.96 =7.97[/tex]

Surface area of  snowman's head=[tex]4 \times \frac{22}{7} \times 9.97=125.33 cm^2[/tex]

Hence the approximate surface area of the snowman's head is 125.33 sq.cm.

so 11/42 = /100

Answer:

11/42 = x/100

Step-by-step explanation:

42 students and 31 are girls

42 -31 = 11 that is the number of boys

boys / total = x/100 to find the percent

11/42 = x/100

Answer:

Step-by-step explanation:

compare with x²+y²+2gx+2fy+c=0

2f=-12

f=-6

center is (7,6)

radius=√((-7)²+(-6)²-76)

=√(49+36-76)

remember that negative it goes down the line the positive it goes up

Answer:Yes

Step-by-step explanation:

Given

Suppose side length of cube is a

If we dilate the cube using a scale factor of 2

Side length becomes 2a

and the surface area becomes [tex]=6(\text{side length})^2[/tex]

Surface area[tex]=6(2a)^2[/tex]

Surface area[tex]=4\times 6(a)^2[/tex]

Thus surface area multiplied by a factor of 4

Now for volume

[tex]V=(\text{side length })^3[/tex]

[tex]V=(2a)^3[/tex]

[tex]V=8(a^3)[/tex]

Therefore volume is multiplied by a factor of 8

Therefore the above statements make sense

Answer: A

Step-by-step explanation:

The correct statement about the volumes of the two cylinders is,

⇒ The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

In the drawing,

s > t

Where, 's' is radius of left hand side cylinder and 't' is radius of right hand side cylinder.

We know that;

Volume of cylinder = πr²h

Hence, Volume is directly proportional to radius.

Larger the radius gives large Volume.

Hence, WE get;

The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.

Thus, The correct statement about the volumes of the two cylinders is,

⇒ The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.

Manny has two part-time jobs. One job pays $10/hour and the other pays $16/hour. ...

Answer:

x = 0

Step-by-step explanation:

The equation of a line is shown by using the formula y = mx+b

But, in special cases like this one, where the line is completely vertical then we use the same formula but we just adjust it.

When a line is completely straight up and down the equation is x = #

Since the line is on the y-axis (or has a x value of zero) the equation is x = 0.

There is no y in this equation because the line is hitting all values of y (which means y is ∞) with only 1 value of x. (As opposed to most equations where one or multiple values of y with one value of x or vise-versa.)

Step-by-step explanation for Surface Area:

So, to find the surface area, you use the formula: [tex]A=lw+l\sqrt{(\frac{w}{2})^2 +h^2 } +w\sqrt{(\frac{l}{2})^2 +h^2 }[/tex]

I'll explain what each part means and why they are like that. (btw, it would help you more if you looked at a rectangular prism I added while you read the explanation :) )

First of all, you do lw because that is the base of the right rectangular pyramid (since you're finding the surface area, you need to find the area of all the surfaces on the pyramid)

You add [tex]l\sqrt{(\frac{w}{2})^2 +h^2 }[/tex] because now you're trying to find the triangular side with the length. You multiply the length, because that's how wide the "triangle" is. You do the square root because of the pythagorean theorem (since you're using the hypotenuse times the length to find that side). The width is divided by two, because as you can see in my attachments, that's how far away the height is from the length (if you look at the base, see where the height line drops in comparison to the length).  (look at my second screenshot)

You add [tex]w\sqrt{(\frac{l}{2})^2 +h^2 }[/tex] for the same reason, except dealing with the width. You're finding the side with the width. You multiply the width by the hypotenuse of the right triangle (look at the third screenshot i attached). The length is divided by two because that's the distance between the bottom of the height line to the w.

I do believe that this should explain the meaning behind each piece of the formula (I'm not sure this is what you asked for lol but it does make understanding it a little easier, I think). To get the answer, you just substitute each variable with those values. So...

[tex]A=(7)(5)+(7)\sqrt{(\frac{(5)}{2})^2 +(12)^2 } +(5)\sqrt{(\frac{(7)}{2})^2 +(12)^2 }[/tex]

A ≈ 183.3

As for the Volume:

[tex]V=\frac{lwh}{3}[/tex]. I'm not 100% on why it's divided by three, but with any volume, you're always going to end up with an answer that is in cubed units. So that explains the three variables in the numerator. I'd like to think the three just has to do with the three variables, but I don't know. Give me the points if you'd like? I don't think this is a proper explanation though.

Good luck!

Answer:

volume = 140 cubic units

area = 183.3 square units

Step-by-step explanation:

I am going to assume we are dealing with a pyramid with a rectangular base. The rectangular base has length 7 units, width 5 units, and height 12 units.

Let's do the volume first since it's simpler.

Volume:

volume of pyramid = (1/3) * (area of base) * height

volume = (1/3) * 7 units * 5 units * 12 units

volume = 140 cubic units

Now we deal with the surface area.

The total surface area of a rectangular pyramid is the sum of the lateral area and the area of the base. The area of the base is the area of a rectangle. The lateral area is the sum of the areas of the 4 triangular sides. Each two opposite sides are congruent. For the base, we have the length and width of the rectangular base, so we can find the area easily.

For the 4 triangular sides, we need to find the the height of the triangles. Since each pair of opposite faces is congruent, we have two triangles we need to find the heights for. I'll call the heights "p" and "q". We use the Pythagorean theorem to find the heights of the triangular faces.

a^2 + b^2 = c^2

(3.5)^2 + (12)^2 = p^2

p^2 = 156.25

p = 12.5

(2.5)^2 + (12)^2 = q^2

q^2 = 150.25

q = 12.25765

Area of triangle = (1/2) * base * height

For two triangles, the base is 5 and the height is 12.5.

For the other two triangles, the base is 7 and the height is 12.25765.

total surface area = area of base + 2(area of triangle with base 5) + 2(area of triangle with base 7)

A = LW + 2(1/2)(base)(height) + 2(1/2)(base)(height)

A = 7(5) + 2(1/2)(5)(12.5) + 2(1/2)(7)(12.25765)

A = 183.3 square units
