Answer:

perimeter ratio: 4 : 3area ratio: 16 : 9

Step-by-step explanation:

The ratio of perimeters is the ratio of corresponding sides.

  first : second = 8 : 6 = 4 : 3 . . . ratio of perimeters

The ratio of areas is the square of the ratio of linear dimensions.

  first : second = 4² : 3² = 16 : 9 . . . ratio of areas

Answer 2

Answer:

look at the explanation <33

Step-by-step explanation:

The first figure is similar to the second figure. The ratio would be 4:3

2/5+7/15 in its simplest form

Answers

Answer:

13/15

Step-by-step explanation:

First convert the fractions to have a common denominator

2/5 = x/15

Cross multiply

2 × 15 = 5 × x

30 = 5x

Divide both sides by 5 to isolate the variable

30 ÷ 5 = x

6 = x

Plug x into the new fraction

6/15

Now add this to the other fraction

6/15 + 7/15

Only add the numerators. The denominators will remain the same number

6 + 7 / 15

13/15

It cannot be reduced anymore so this is simplest form

Step-by-step explanation:

Solve for x. Round answer to the nearest tenth (0.1).

Answers

Answer:

x = 9.9

Step-by-step explanation:

This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.

In this case, multiply. The side measurement of 1 has 7.

1 x 7 = 7

In the same, you must multiply 7 with √2

x = 7 * √2 = 7√2.

√2 = ~1.414

7 x 1.414 = 9.898

Round to the nearest tenth:

9.898 rounded to the nearest tenth = 9.9

x = 9.9

~

Answer:

9.9 is your answer

Step-by-step explanation:

by using Pythagoras law

p²+b²=h²

7²+7²=x²

x=√{2×49)=7√2or 9.9 is your answer

share was 60 cards, what was Gina's share of the cards?
25
50
100
200

Answers

Answer:

50

Step-by-step explanation:

Wen: 30% of the total number of cards = 60 cards

Set this up as an equation

30/100 = 60/x

Cross multiply

30 × x = 100 × 60

30x = 6000

Divide both sides by 30 to isolate the variable

x = 200

There are 200 cards total

Gina: 25% of the total 200 cards

Set this up as an equation

25/100 = x/200

Cross multiply

25 × 200 = 100 × x

5000 = 100x

Divide both sides by 100 to isolate the variable

50 = x

Gina's share is 50 cards

We have to assume the triangle is a right triangle.

In a 30°-60°-90° right triangle the side lengths have the ratio ...

  short side : long side = 1 : √3

This lets you write the proportion ...

  x/15 = 1/√3

Multiplying by 15 gives ...

step 3: place the rise over run in decimal form. say its 5 to the side and 2 up 2/5 (if it was a negative rise such as 2 down it would be -2/5)

step 4= find where it crosses the y line such ex: 0,8 it would be 8 (if it were negative it would be 0,-8: -8)

Probability of blue is 0.4 red 0.3 yellow 0.3 there are 30 blue cubes in box what total number of cubes in box

Answers

Answer:

75

Step-by-step explanation:

The computation of the total number of cubes in box is shown below:

Given that

The probability of blue = 0.4

For red it is 0.3

And, for yellow it is 0.3

As if there is 30 blue cubes in a box

So for red it is = 30 × 0.3 ÷ 0.4 = 22.5

And, for yellow = 30 × 0.3 ÷ 0.4 = 22.5

Now the total number of cubes in a box is

= 30 + 22.5 + 22.5

= 75
