Answer:

A) 5x-7y=42

Step-by-step explanation:

We know that 5 x 7 = 35 then add 7 = 42

We divide 5 and 7 by 5/7

5/  5/7 = 0.1

7/ 5/7 = 0.2

We find 0.1 = 1/10 and we know that 1/10 of 35 is 3.5

We find 0.2 = 2/10 and we know that 2/10 of 35 is 7 so the answer 7 matches.

We then use 7 for y and keep 5 for x.

Answer:

square root of 68, or 8.24

Step-by-step explanation:

You have to use the Pythagorean theorem. 2 and 8 will both be squared. 2 squared is 4, and 8 squared is 64. Add those up and you get 68. Since the Pythagorean theorem states that a squared + b squared = c squared, you have to square C.

Step-by-step explanation:

Step 1:  Use two points

What was his mean test score.
Answer:

Answers

Answer:

His mean test score was 85.

Step-by-step explanation:

The mean of something is the average of a data set.

To find the average, we find the sum of all the scores, and divide it by the number of scores there are.

Let's find the sum:

89+73+84+91+87+77+94

595

There are 7 total scores.

595/7=85

Answer:

85

Step-by-step explanation:

Add 89+73+84+91+87+77+94=595/7=85

Answers

76 82 87 93 95 98

Mean -
76+82+87+93+95+98 = 531
531/6 = 88.5

Range -
98 - 76 = 22

Median -
Because there are 6 numbers you have to find the average of the middle two
87+93 = 180
180/2 = 90

Mode -
No number is repeated so there is no mode.

Answer:

Mean: 88.5

Median:90

Mode:98

Step-by-step explanation:

For mean, what you need to do is add all of those numbers up and divide them by how many you have. So once you add up all those numbers, divide them by six because there are 6 numbers. For the median, order the numbers from smallest to biggest and cross off every one until you get left with the number in the middle. If there is an even number of numbers and there are two middle ones, add them together and divide them by 2. For mode, it’s the one with the most. Please don’t hesitate to write back if you need anything else or any of the answers are incorrect. Have an amazing day!!

Answers

Answer:

x = 20

y = 10

Step-by-step explanation:

Since we have a right triangle then:

sin(60) = 10√3/x ⇒ x = 10√(3)÷sin(60) = 20

cos(60) = y/20 ⇒ y = 20×cos(60) = 10

Answer:

Option B)

The value of x is 20 and y is 10

Step-by-step explanation:

Here, in a given right triangle

ΔABC, m∠B = 90°

Now,

tanθ = opposite ÷ adjacent

tan 60° = 10√3 ÷ y

√3 = 10√3 ÷ y

y = 10√3 ÷ √3

y = 10

Now,

sinθ = opposite ÷ hypotenuse

sin 60° = 10√3 ÷ x

√3 ÷ 2 = 10√3 ÷ x

√3 × x = 10√3 × 2

x = 20√3 ÷ √3

x = 20

Thus, The value of x is 20 and y is 10

The addition is one of the four fundamental mathematical operations. The correct option is B.

What is Addition?

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Given that the price of a stock decreased $4 per day for 3 days and increased $2 per day for 4 days. Therefore, The change in the price of the stock is,

Change in the price = (-$4 × 3 days) + (+$2 × 4 days)

                                  = -$12 + $8

                                  = -$4

Hence, the correct option is B.

What is metric conversion?

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

The volume in liters is equal to the milliliters divided by 1,000.

The given measurement is 1250 ml.

We know that, 1 liter = 1000 ml

To convert milliliters to liters, divide the given quantity by 1000.

Here, 1250/1000 = 1.25 l

Therefore, 1250 ml in liters is equal to 1.25 l.
