Answer:

-12

Step-by-step explanation:

12 - 15 = -3

4 ( -3 )

= -12

Answer: -12

Step-by-step explanation:

We have 4[12 -15]

Next, we have subtract in the parentheses since it's part of PEDMAS

12-15

After that, we get -3. Whenever a you multiply a whole number with a negative number, the whole becomes negative.

12- 15= -3

And Lastly, we multiply.

4x -3= -12

Hope this helps!

Given:

The weight in gram of 15 packets of sweets are: 55.0, 55.3, 55.3, 55.3, 55.5, 55.6, 55.8, 55.9, 56.1, 56.2, 56.2, 56.4, 56.7, 56.7, 56.8.

To find:

The value of the median and quartiles.

Solution:

We have,

55.0, 55.3, 55.3, 55.3, 55.5, 55.6, 55.8, 55.9, 56.1, 56.2, 56.2, 56.4, 56.7, 56.7, 56.8

Divide the data set in two equal parts.

(55.0, 55.3, 55.3, 55.3, 55.5, 55.6, 55.8), 55.9, (56.1, 56.2, 56.2, 56.4, 56.7, 56.7, 56.8)

Divide each parenthesis in two equal parts.

(55.0, 55.3, 55.3), 55.3, (55.5, 55.6, 55.8), 55.9, (56.1, 56.2, 56.2), 56.4, (56.7, 56.7, 56.8)

Now,

First quartile = 55.3

Second quartile = Median = 55.9

Third quartile = 56.4

Therefore, the median is 55.9 and the three quartiles are 55.3, 55.9, 56.4 respectively.

Answer:

$100.02

Step-by-step explanation:

*Sales tax is always applied after the discount/coupon

1. Find how much Hana had spent on pants. Since she had bought 2 pairs of pants, and they are $26.59 each, we would have to multiply 26.59 by 2. So,

26.59 times 2 is 53.18.

Hana spent $53.18 on pants

2. Find how much Hana had spent on a coat. Since she had bought 1 coat, and they are $49.00 each, we would have to multiply 49.00 by 1. So,

49.00 times 1 is 49.

Hanna spent $49 on coats

3. Find how much Hana spent on clothes. Since she spent $53.18 on pants and $49 on coats, we would have to add 53.18 and 49. So,

53.18+49=102.18

Hanna spent $102.18 on clothes

4. Find how much Hana "spent" after using the coupon. Since the problem says the coupon helps Hana save $10, we need to subtract 10 from 102.18(the total amount of money Hana spent on clothes before using the coupon). So,

102.18-10=92.18

Hanna "spent" $92.18 on clothes after using the coupon

5. Find how much was the total purchase. Sales Tax is the amount of money that needs to be added to the price. Since the price is $92.18 and the sales tax is $7.84, we need to add 7.84 to 92.18. So,

7.84+92.18=100.02

The total purchase is $100.02

Answer: 6.25

Step-by-step explanation:

a2 + b2 = c2

b2 = c2 - a2

b2 = (8*8) - (5*5)

b2 = 64 - 25

b2 = 39

b = [tex]\sqrt{39}[/tex]

b = 6.25

Answer: 107 I think

Step-by-step explanation:

The average temperature on Earth is 225 degrees higher than the average temperature of Jupiter.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Jupiter's temperature is -166, and Earth's temperature is 59.

We have to find the temperature difference between the earth and Jupiter.

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

The average temperature on Earth and the average temperature on Jupiter are obtained by applying the subtraction operation as,

Δt= T(earth) - T(jupiter)

Δt=59-(-166)

Δt=59+166

Δt=225 degrees

Thus, the average temperature on Earth is 225 degrees higher than the average temperature of Jupiter.

Answer:

D ...

Step-by-step explanation:

Use the Pythagorean Theorem to figure out which triangle is NOT a right triangle. Square each leg and add them together. Then, square the hypotenuse (longest side). If the sums are equal, then the triangle IS a right triangle.

Pythagorean Theorem:

a(a) + b(b) = c(c) ; a squared plus b squared equals c squared

6(6) + 24(24) =? 26(26) ; leg a =6, leg b=24, hypotenuse=26

36 + 576 =? 676 ; simplify

612 =? 676 ; is 612 equal to 676?

Erotically angles are opposite each other and equal the same degree.

In the image 5x and 120 are vertical angles so 5x needs to equal 120.

X = 120/5

X = 24

Answer:

X=24 degrees.

Step-by-step explanation:

120/5=24. You divide by 5, because the angles will be congruent, and the top angle is 5*_=120. And 5*24=120, so x=24

Answer:

in previous material it was shown that the digit sum of the product of two integers is equal to the digit sum of the product of the digit ... For instance, 66/8 = 8.25. ... For example, 35/7=5; the digit sum of the quotient is 5 and the digit sum of 35 is 8.

Missing: 59.4 ‎| Must include: 59.4

Answer:

7.2

Step-by-step explanation:

Change the divisor 8.25 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

5940 ÷ 825 = 7.200

and therefore:

59.4 ÷ 8.25 = 7.200

Both calculated to 3 decimal places.
