Answers

Answer 1

Answer:

Adjacent sides are in the ratio 5 : 12

That means,

Let length = 12x and breadth = 5x

Perimeter = 34

2(l+b) = 34

12x + 5x = 17

17x = 17

x = 1

Lenth =12 cm

Breadth = 5 cm

By Pythagorean theorem

The length of the diagonal of rectangle = 13 cm

Step-by-step explanation: Work is attached on the image.

Answer:

OQ = 11

Step-by-step explanation:

Segment Addition Postulate

If a third point B lies on a line segment with endpoints A and C, then AB + BC = AC

Given:

OP = 17QP = 6

Q is the point on the line segment OP, so:

⇒ OQ + QP = OP

Substitute the given values of OP and QP to find OQ:

⇒ OQ + 6 = 17

⇒ OQ + 6 - 6 = 17 - 6

⇒ OQ = 11

Step-by-step explanation:

first ,let’s calculate the number of bags made by the company that have both buttons and zips :

150-(43+38+34)

=35

a bag that has buttons : either has buttons but no zips  or  has both buttons and zips

Then

The number of the bags that have buttons is :

43+35 = 78

Cooper was out at a restaurant for dinner when the bill came. His dinner came to $28. After adding in a tip, before tax, he paid $33.32. Find the percent tip.

Answers

Cooper left his dinner server a 19% tip.

To find the percent tip, we need to first subtract the cost of the meal from the total amount paid, which will give us the tip amount:

Tip amount = Total amount paid - Cost of the meal

Tip amount = $33.32 - $28

Tip amount = $5.32

Now we can calculate the percentage of the tip by dividing the tip amount by the cost of the meal and multiplying by 100:

Percent tip = (Tip amount / Cost of the meal) x 100

Percent tip = ($5.32 / $28) x 100

Percent tip = 0.19 x 100

Percent tip = 19%

Therefore, Cooper gave a 19% tip on his dinner.

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{XZ}[/tex] = [tex]\frac{XY}{12}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

What are trigonometric ratios in terms of a right-angle triangle?

tan = opposite/adjacent.

In reference to the angle of 30° opposite side is XY and the hypotenuse is 12 units.

Write an equation for the line parallel to the given line that contains C.

Answers

Answer:  [tex]\textsf{y = 5/7x + 51/7}[/tex]

-------------------------------------------------------------------------------------------------------------

Given: [tex]\textsf{Goes through (1, 8) and is parallel to y = 5/7x + 7}[/tex]

Find:  [tex]\textsf{Write an equation that follows that criteria}[/tex]

Solution: We know that our equation is going to parallel to the line that was given therefore the slope would stay the same at 5/7.  We also have a point so we can plug in the values into the point-slope form, distribute, and solve for y.

Plug in the values

[tex]\textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}[/tex][tex]\textsf{y - 8 = 5/7(x - 1)}[/tex]

Distribute

[tex]\textsf{y - 8 = (5/7 * x) + (5/7 * (-1))}[/tex][tex]\textsf{y - 8 = 5/7x - 5/7}[/tex]

Add 8 to both sides

[tex]\textsf{y - 8 + 8 = 5/7x - 5/7 + 8}[/tex][tex]\textsf{y = 5/7x - 5/7 + 8}[/tex][tex]\textsf{y = 5/7x + 51/7}[/tex]

Therefore, the final equation that follows the description that was provided in the problem statement is y = 5/7x + 51/7.

Step-by-step explanation:

you start by doing 349(0.30) which would be 104.7

349-104.7=244.3

next you do 244.3(.15)=36.645

244.3-36.645= $207.655

First just do $349 times .70 to get 244.3 because .70 +.30 =1 so 100% of the price. Next take the 244.3 and multiply it by .85 and get 207.655 and round to $207.66.

Answers

Using it's concept, it is found that the probability that the first three balls are drawn out of the box alternated in colour is of 0.1541 = 15.41%.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Considering the situation described, the ways that alternate colored balls can be taken, and their probabilities, are given as follows:

R(5/8) - W(3/9) - R(5/11).W(3/8) - R(5/10) - W(5/11).

Hence the probability is given by:

[tex]p = \frac{5}{11} \times \frac{3}{9} \times \frac{5}{11} + \frac{3}{8} \times \frac{5}{10} \times \frac{5}{11} = 0.0689 + 0.0852 = 0.1541[/tex]
