Answer:
C= 7y +150
850
250
Step-by-step explanation:
The cost is 7 times y, the number of yearbooks, plus 150, the upfront cost.
7 times 100 is 700, plus 150 is 850.
1900-150 is 1750 divided by 7 is 250

Look at the picture and answer the question: What is the length of QS?
Step-by-step explanation:
firstly draw the triangle and label it. (you will find the picture down)
Now this remind us with the cosine rule. (you will find the picture down)
This rule says that the square of the given length of the side of a triangle is equal to the sum of the squares of the length of other sides minus twice their product and multiplied by the cosine of their included angle.
So using that rule we can say that:
[tex]QS^{2}[/tex] = [tex]QR^{2} +SR^{2} - 2(QR)(SR)(cosR)[/tex]
square root both sides, so you will have QS alone in one side.
QS = [tex]\sqrt{ [QR^{2} +SR^{2} - 2(QR)(SR)(cosR)]}[/tex]
plug in the values we have and y=this will yield:
QS = [tex]\sqrt{ [11^{2} +16^{2} - 2(11)(16)(cos38)] }[/tex] = 9.98099267 = 10

The minimum number of triangles needed to construct the polygon Sophia made is 3. Which could show Sophia’s polygon?
A 4-sided figure.
A 6-sided figure.
A 5-sided figure.
A 4-sided figure.
Sophia's polygon is, ''5 - sided polygon'' or ''Pentagon.''
What is mean by Triangle?Any triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
The minimum number of triangles needed to construct the polygon Sophia made is 3.
And, To find Sophia's polygon.
Now, We know that;
The Shape of Pentagon is made with 3 triangles.
Hence, Sophia's polygon is known as,
⇒ 5 - sided polygon or Pentagon.
Therefore, We get;
⇒ The polygon make by Sophia's is, Pentagon.

Maria has a new fish tank for her goldfish. The tank measures 912 inches long, 312 inches wide, and 612 inches tall.
Part A:
What formula should Maria use if she wants to know the volume of her new fish tank?
Part B:
Using the formula you wrote for Part A, what is the volume of Maria's new fish tank?
I'm giving out Brainliest!
Step-by-step explanation:
step 1. V = LWH. L = length. W = width. H = height.
step 2. V = (912)(312)(612) = 174,140,928 in^3.
The volume of Maria's new fish tank is 174,140,928 cubic inch.
It is required to find the volume of Maria's new fish tank.
What is cuboid?In geometry, a cuboid is a solid shape or a three-dimensional shape. A convex polyhedron that is bounded by six rectangular faces with eight vertices and twelve edges is called a cuboid.
Given :
Maria has a new fish tank for her goldfish.
The fish tank is in the shape of cuboid.
length=912 inches
width=312 inches
Height=612 inches
Part A
The formula of volume of her new fish tank
Volume=length ×width × height.
Part B
Volume=length ×width × height.
By the use of formula we have,
V = (912) ×(312) ×(612)
V= 174,140,928 cubic inch.
Therefore, the volume of Maria's new fish tank is 174,140,928 cubic inch.

Dracula jumped 5 times every 30 minutes at that rate, how long,in minutes will it take to jump 6 times?
Answer:
36 minutes
Step-by-step explanation:
If I read this correctly, Dracula jumps 1 time every 6 minutes. If he jumped 5 times in 30 minutes, then that means when he jumped a sixth time, it was 36 minutes that passed since:
30 / 5 = 6
So, if he were to jump a sixth time:
30 + 6 = 36
Therefore, Dracula jumps 1 time per 6 minutes.

15 ? ( Zearn)
ill give brainliest if you help me + 20 points :)
Answers:
21.75
1.37
10
15
Step-by-step:
Dozen flyers:price
4:7.25
12:x
To solve this mulitply 7.25 by 3 (because this is what we multiplied 4 by to get 12) 7.25*3=21.75
Question 2:
We can write teh following equation
.49+.22(x-1)=price
This is essentially saying that we pay .49 for the first ounce and .22 for every ounce after that
We can plug in an x value to get
.49+.22(5-1)
.49+.22(4)
.49+.88
1.37
Question 3:
We can write the following equation
x+2=y
We need to find out what happens when x=8
8+2=10
Question 4:
We can solve this with ratios
x:y
1.5:4.5
5:x
To solve just multiply 4.5 by 10/3 and get 15
We can just multiply
Answer:
1. 7.25/4=1.8125 so 1.8125x12=21.75
2. 0.49+(0.22x4)=1.37
3. rule is x+2=y so x=8 then y=10
4.rule is 3(x)=y so x=5 then y=15
