Answer:

y = 15

Step-by-step explanation:

We need to solve for k

y = x

21 = 7k  Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Answer:

\(x = 4 \times {10}^{2} \)

Step-by-step explanation:

Let the number be 'x'.

According to the question ,

\((4 \times {10}^{3} ) \times x = 16 \times {10}^{5} \)

Dividing both the sides by 4 × 10³ :-

\( = > \frac{4 \times {10}^{3} \times x}{4 \times {10}^{3} } = \frac{16 \times {10}^{5} }{4 \times {10}^{3} } \)

\(=> x = \frac{16}{4} \times (10^{5-3})\)

\( = > x = 4 \times {10}^{2} \)

\((-85) \times (-29) + 85 \\ \\ 2465 + 85 \\ \\ 2550.\)

Answer:

(-85) x (-29) + 85

-85 x -29 = 2465

2465 + 85 = 2550

answer 2550

Answer:

k < 50$

Step-by-step explanation:

She wants the keyboard for less than 50$, so the price, k, is less than 50 in this inequality.

Answer:

k < 50

Step-by-step explanation:

The price (k) has to be UNDER $50

So, k is less than $50

Inequality:

k < 50

This means when the price is less than $50, Nita will buy

Answer:

78.5 cm2

Step-by-step explanation:

The formula for the area of a circle is A = πr^2, where π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

Since the diameter of the circle is 10, we can find the radius by dividing the diameter by 2:

r = d/2 = 10/2 = 5

Now we can plug in the value of r into the formula:

A = πr^2 = 3.14 x 5^2 = 78.5

Therefore, the area of the circle with a diameter of 10 is approximately 78.5 square units.

The area of the given picture frame is 177.5 cm².

Given,

Length of square = 16 cm

The diameter of the circle cut out = 10 cm

We have to calculate the area of the picture frame.

First, we will find out the area of the square.

The area of the square = a² = 16 × 16 = 256 cm²

Now, we will find out the area of the circle that is being cut out from the square.

Area of the circle = πr² = 3.14 × 5² = 78.5 cm²

Then the area of the picture frame = Area of the square - the area of the circle

                                                    = 256 cm² - 78.5 cm²

                                                    = 177.5 cm²

Therefore, the required area of the square frame is 177.5 cm².

Answer:

10:8

Step-by-step explanation:

5*2=10

4*2=8

10:8

Answer:

the answers equivalent to 5:4 is 10:8

Step-by-step explanation:

The reason I only chose 10:8 is because all the other answers are not even multiples of 5 or 4 or they were multiples of 5 and 4 but they were not multiplied by the same number.

Example:

25:15 = okay so 5 can go into 25, 5 times but 4 cannot go into 15

20:19 =  okay so 5 can go into 20, 4 times but 4 cannot go into 19

30:20 = though 5 can go into 30 and 4 into 20 they are not multiplied by the same number

15:16 = though 5 can go into 15 and 4 into 16 they are not multiplied by the same number

and last but not least 100:85 = okay so 5 can go into 100, 20 times but 4 cannot go into 85

So it leaves 10:8= 5 can go into 10, 2 times and 4 can go into 8, 2 times so this is your answer.

Answer: 0.425 is a decimal number of 17/40 7.25 to the nearest thousands is 0 7.25 to the nearest hundreds is 0 7.25 to the nearest tens is 10 Check and cancel the factors of 84 and 100 if any factors in the numerator and denominator can be cancelled each other:

=(21 x 4)

(25 x 4)

84/100

=21/25

0.84 as a fraction is equal to 21/25

First things first, if you don't know what a numerator and a denominator are in a fraction, we need to recap that: Here's the little secret you can use to instantly transform any fraction to a decimal: Simply divide the numerator by the denominator: That's literally all there is to it! 5/12 as a decimal is 0.41666666666667, but just write 0.4. Next 5.75=

2.  \(10\frac{7}{25}\)  =  \(\frac{257}{25}\)  =  10.28  =  10 (rounded)

3.  0.84  →  \(\frac{0.84*100}{1*100} = \frac{84}{100}\)  =  \(\frac{21}{25}\)  (lowest terms/simplest form)

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30
