Can someone answer this and give an explanation

Answer:

The angles are complementary, hence the answer is the second one.

Step-by-step explanation:

Since 90° - 65° = 25°, we know that 5x =25°, hence x is equal to 25° ÷ 5, which is 5°, hence, x = 5° and the answer is the second one

Hope this helps :))

Answer:

  (b)  Complementary; x = 5

Step-by-step explanation:

Angles are complementary when the total of their measures is 90°. Angles are supplementary when the total of their measures is 180°. A right angle has a measure of 90°, so any pair of angles that has the same total measure as a right angle are complementary angles.

__

The little square in the corner of the figure indicates that angle is a right angle, and has a measure of 90°. The ray headed off to the northeast divides that 90° angle into two parts, labeled 65° and 5x°. In math, the whole is the sum of the parts, so the 90° angle is the sum of the 65° and 5x° angles.

Those two angles total 90°, so they are complementary.

Now that you understand the sum of the two marked angles is 90°, you can use that fact to write an equation:

  65° +5x° = 90° . . . . equation relating the complementary angle measures

This is a 2-step linear equation, so is solved the way that kind of equation is solved.

  5x° = 25° . . . . . step 1: add the opposite of 65° to get the x-term alone

  x = 5 . . . . . . . . .step 2: divide by the coefficient of x to get x alone

The angles are complementary, and the value of x is 5.

Additional comment

In order to keep the equation true, whatever operation we perform on one side of the equation must also be performed on the other side. When we say "add -65°", we mean that value is added to both sides of the equation. Above, we have skipped the steps of showing that addition and the subsequent simplification. (Similarly, we skipped the steps showing the division and the simplification process.)

  65° +5x° = 90° . . the original equation. We want to eliminate the 65° term.

  65° +(-65°) +5x° = 90° +(-65°) . . . . . add -65° (to both sides)

  (65° -65°) +5x° = (90° -65°) . . . . . simplify the expressions a bit

  0° +5x° = 25° . . . . . . . . . . . do the subtraction

  5x° = 25° . . . . . . . . . . . 0 is the identity element for addition. Adding it changes nothing.

Answer:

702

Step-by-step explanation:

The best way to do it is to divide 13 into 702. 13 doesn't go into 7 but it does go into 70 5 times. 70 - 65 = 5. Once you bring down the 2, 5 turns into 52 which 13 goes evenly into it 4 times. So your answer for that is 54. Then to get your number you multiply 54 with 13 and you get 702. So 702 is your answer.

The answer for the 1st bag is option B = 1/3

The answer for the 2nd bag is option C = 5/9

Number of marbles in 1st bag - 15 (6 red, 4 blue & 5 green)

Number of marbles in 2nd bag - 9 (3 red, 1 blue & 5 green)

The formula of probability = Total number of events in the outcome /total number of outcomes.

Now the probability that Aakesh will select a green marble from the 1st bag is 5(green marbles)/15(total number of marbles in 1st bag)

That is 5/15=1/3

Now the probability that Aakesh will select a green marble from the 2nd bag is 5(green marbles)/9(total number of marbles in 1st bag)

That is 5/9

C.) 5/9

☆☆●◉✿Step-by-step explanation:✿◉●☆☆

First we must figure out how many marbles we have in total.

Meaning we will add all of the marbles together in bag one and then bag two.

Bag one: 6+4+5= 15

Bag two: 3+1+5= 9

Total= 24 marbles

Now we will try and figure out how many greens are in the total amount of marbles.

Amount of green marbles in bag one: 5

Amount of green marbles in bag two: 5

Total green marbles: 10

The third and final step!

10/24 is the amount of green marbles so the answer is C!

Answer: divide by 6?

Step-by-step explanation:

What is the least positive integer by which 24 should be divided so that the resulting integer is a perfect square?

If we actually guess and check by dividing by 1, then 2, then 3, then etc. we will get the answer. I tried and divided by 6, which is 4, which is a perfect square. Do not trust me completely on this, for I am not quite sure.

Answer:

D. (1/3)

Step-by-step explanation:

If we look at the graph, there are a total of 12 squares, which means we have a denominator of 12.
Next if we look at the answer, it is asking if for the chance of us getting a number under 5 and is a heads, which means there are 4 squares that would apply to this (They have to be both under 5 and be a heads)

This results in us having a numerator of 4.

So If we put it together we get 4/12, which when simplified equals 1/3!

Answer:

A) The actual length of the microchip is 3 centimeters.

B) The actual width of the microchip is 2 centimeters

C) The ratio of the original scale drawing measurements to the new scale drawing measurements is 2 inches to 3 inches.

Step-by-step explanation:

A) actual length = scale length × reciprocal of scale factor

The scale is 2 inches to 1 centimeter, so the scale factor is. 2in/1cm  The reciprocal of the scale factor is. 1cm/2in The length of the chip in the scale drawing is 6 inches.

= 6 in.  x  (1cm/2in)

= 3 cm

B) actual width  = scale width × reciprocal of scale factor

= 4 in. x  (1cm/2in)

= 2 cm

C) The original scale drawing, the microchip was 6 inches long. It is now 9 inches long.

Ratio: 6in/9 in 3in/2in

The microchip was 4 inches wide. In the new scale drawing, the microchip is 6 inches wide.

Ratio: 4in/6in  2in/3in

Step-by-step explanation:

Reason:

x = number of textbooks

650x = weight of all x books, at 650 grams each

3 kg = 3000 g

650x = 3000

x = 3000/650

x = 4.615 approximately

Round down to the nearest integer. This is because 4 textbooks weigh 4*650 = 2600 grams = 2.6 kg; while 5 textbooks weigh 5*650 = 3250 grams = 3.25 kg which is over the weight limit.

This means 4 books is the most the rucksack can hold. This is of course only when we have 4 of the same exact book.

Answer:

Given The base of a rectangular prism has an area of 12 sq cm. The height of the rectangular prism is 3 cm

Now volume of the rectangular prism is given by length x width x height

Also area of rectangular prism is 12 sq cm and height of the rectangular prism is 3 cm.

But area of rectangle is length x width

Now volume of the rectangular prism           V = 12 cm^2 x 3 cm         V = 36 cm^3Therefore volume of the rectangular prism will be 36 cm^3

Answer:

Step-by-step explanation:

Volume of rectangular prism=w x h x l

V=12cm^2 x 3 1/3

V=12cm^2 x 1

V=12cm^3
