Step-by-step explanation:

8/16=8:16

2/4=2:4

Answer:

Yes, the ratios 2/4 and 8/16 form a proportion. To check if two ratios form a proportion, you can cross-multiply and see if the products are equal. In this case, 2 x 16 = 4 x 8 = 32, so the products are equal. Therefore, the ratios form a proportion.

Answer : 14hours

Step-by-step explanation:

If a camera costs 150 dollars and she already has 25 dollars, she needs 125 dollars more

9x14=126 so she needs to works 14 hours

The number of hours needed to babysit in order to purchase the camera is 14.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Amount in her account = $25

Amount earned per hour = $9

The expression to find the number of x hours to buy the camera.

25 + 9x = 150

9x = 150 - 25

9x = 125

x = 13.89

x = 14

Thus,

The number of hours needed is 14.

Answer:

[tex]0.34p + 0.49f = 5.00[/tex]

Step-by-step explanation:

Given

[tex]Cost = \$5.00[/tex]

[tex]Postcards = \$0.34[/tex]

[tex]First-class = \$0.49[/tex]

Required

Represent as an equation

If 1 postcard costs $0.34, then p postcards cost $0.34p

If 1 first-class costs $0.49, then f first-class cost $0.49f

The addition of p postcards and f first-class equals the total cost of mailing the package.

So, we have:

[tex]0.34p + 0.49f = 5.00[/tex]

Answer:

≈ 50.7 cm²

Step-by-step explanation:

The area (A) of Δ XYZ is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height ), that is

A = [tex]\frac{1}{2}[/tex] × XY × YZ

Calculate YZ using the tangent ratio in the right triangle

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{YZ}{XY}[/tex] = [tex]\frac{x}{11}[/tex] ( multiply both sides by 11 )

11 × tan40° = x , that is

YZ ≈ 9.23 cm

Thus

A = [tex]\frac{1}{2}[/tex] × 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )

Answer:

Step-by-step explanation:First, divide 2.20 by 5 to find the price of a single stamp.

2.20 ÷ 5 = 0.44

One stamp cost $0.44

Now, you multiply this by 7 to find the cost of seven stamps.

0.44 × 7 = 3.08

In 2012, seven stamps cost $3.08

Answer:

$3.08

Step-by-step explanation:

so 5= 2,20

dividing them will get .44

Step-by-step explanation:

The type of triangle is an obtuse triangle.

A triangle is a 3-sided polygon.Every triangle has three sides and three angles, some of which may be the same. When the angles are thesame, the triangle is called an equilateral triangle.

An obtuse triangle is a type of triangle in which one of it's angles is more than 90°.

An acute triangle is a type of triangle in which none of it's angles is UpTo 90°

Also a right triangle is a type of triangle in which one of the angles is exactly 90°.

Therefore since one of the angles is 110 and it is greater than 90°, the angle is an obtuse triangle.

Explanation:

"Without replacement" means the card selected is not put back, and we do not put a copy of that card into the deck.

We have 5 yellow cards out of 5+9+1 = 15 cards total. The probability of picking yellow is 5/15 = 1/3. Let A = 1/3.

After picking that yellow card, we have 5-1 = 4 yellow left out of 15-1 = 14 total. The probability of picking another yellow card, after the first one is not replaced, is 4/14 which reduces to 2/7. Let B = 2/7.

Multiply the values of A and B

A*B = (1/3)*(2/7) = (1*2)/(3*7) = 2/21

The probability of picking two yellow cards, without replacement, is 2/21

Step-by-step explanation:

Answer:

ATQ= 15 is 1/5 and 312 is 3/12 sorry for that

1/5(N-10)=6-3/12

1/5N -2= 6/1 - 3/12

1/5N-2 = 72 -3/12 = 69/12

69/2 = 5.75

1/5N = 5.75-2 = 3.75

N= 3.75/.2

Answer:

exact form: x=17/10

Decimal form: x=1.7

mixed number form: 1 7/10

Answer:

x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)

Step-by-step explanation:

3(5-x) = 7x - 2

3 * 5 - 3* x = 7x - 2 (brackets means multiply)

15 - 3x = 7x - 2 (when over equal sign negative changed to positive)

15 + 2 = 7x + 3x

17/10 = 10x/10 (cross-cancel cuz u tryna isolate the x)

17/10 = x

Answer:

Yep, look at the example below:)

Step-by-step explanation:

Basically, you start off by taking the number in front of the parantheses (in this case 6) and multiply it with the other numbers inside the parantheses (so that would be 4 and -5). 6 times 4 is 24, 6 times -5 is -30, and now you combine the two numbers (24 and -30).And voila:) !

6(4-5)

= 24-30

=  -6
