The measures of the angles in △ABC are given by the expressions in the table.

Angle Measure
A 65°
B (3x−10)°
C ​​​​(2x)∘
Find the value of x. Then find the m∠B and m∠C.

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

Answer:

B.

Step-by-step explanation:

Because they want it to be less than 50 dollars or the card will overdraft. so its 9.99 + 1.29 > or equal to n. They want the sum of 9.99 plus 1.29 times a number to be less than 50.

Answer:

1. 11   ( (3x2) + 5)

2. 16 ( (3x2) + (2x5) )

3. 19  ( (3x5) + (2x2) )

4. 54 ( ( 10x2) + (4x5) + (7x2) )

5. 50  ( (8x5) + (5x2) )

6. 34   ( (7x5) + (4x5) )

Hope I got all them correct!

Sophia's polygon is, ''5 - sided polygon'' or ''Pentagon.''

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.

Answer:

1. p <= 5

2. v < 9

3. g != 8

4. d >= 6

5. t > 20

Step-by-step explanation:

<= is "less than or equal to"

!= is "not equal to"

>= is "greater than or equal to"

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.

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.

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

Answer:

452.16 cm²

Step-by-step explanation:

3.14 × 12² = 452.16 cm²

Answer:

452.16

Step-by-step explanation:

Comes down to knowing the Area of a Circle formula- A = πr².

A = area

r = radius, in your case, 12

A = π(12)² = 452.16cm²

Answer:

[tex]x=\frac{4}{3}[/tex]

Step-by-step explanation:

Use cross multiplication

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
