What is 7x90? im only in 3 grade and my teacer asked me to answer the problem and i have no clue

Answers

Answer 1

Answer:

630

Step-by-step explanation:

Just add 90 seven times. (90+90+90+90+90+90+90=630) Hope this helps! Have a good day/night.

Answer 2

Answer:

7 x 90 = 630

Step-by-step explanation:

If you're not sure how to solve it, i will help you!!

Write it like this on paper:

90

x 7

now multiply them diagonal, for example, you would multiply 0 x 7, and then write it down, and it gives you this:

90

x 7

  0

then you would multiply 9 times 7, which is 63, and put it in front of the 0, so you would have something like this:

90

x 7

630

what is the value of "Y" to the "2nd" power minus "X" to the "2nd" power when "Y" = 6 and "X" =5

Answers

Answer:

11

Step-by-step explanation:

y^2 - x^2

y = 6, x = 5

6^2 - 5^2

When using exponets we multiply a number by itself as many times as the exponet says, so in this case we multiply 6 x 6 and 5 x 5

6 x 6 = 36  5 x 5 = 25

36 - 25 = 11

Answer:

a) 8/11 x 5/3

b) It will be positive. When we have an even number of negatives, the result will be positive ( (-) + (-) = +).

Step-by-step explanation:

a) -8/11 / -3/5

1) -8/11 ÷ (-3/5)

Write the complex fraction as a division expression. Use parentheses because our second fraction is a negative.

2) 8/11 ÷ 3/5

When we have an even number of negatives, the result will be positive ( (-) + (-) = +).

3) 8/11 x 5/3

Dividing is the same as multiplying the second part of the fraction flipped.

4) 40/33

Multiply them: 8 x 5 / 11 x 3

Since the question wants you to write as a multiplication expression, this is the answer:

8/11 x 5/3.

which graph represents the inequality y < 2x +3 correctly

Answers

Answer:

im not sure , sorry

Step-by-step explanation:

Answer:

Option C

Step-by-step explanation:

Graphing inequality:

1) First plot y = 2x + 3 as a dotted line as y is less than x

Put x = 0, y = 2*0 +3 = 0 + 3 = 3    ⇒  (0, 3)

Put x = 1  , y = 2*1 + 3 = 2 +3  = 5    ⇒(1 , 5)

Put x = -1,  y =2*(-1)+3 ⇒ -2+3 = 1    ⇒ (-1,1)

Mark these three points, and draw a dotted line.

2) Shade the area bellow the dotted line as y < 2x + 3

Check: take a point in the shaded area. (1 , -1)

    -1 < 2*1 + 3

   -1 < 2 +3

   -1 < 5

The condition is satisfied.

  31.6°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the trig function relating the sides opposite and adjacent an acute angle in a right triangle. It tells you ...

  Tan = Opposite/Adjacent

__

The tangent of angle B is ...

  tan(B) = AC/CB

  tan(B) = 28.2/45.8

The angle is found from the tangent using the inverse tangent function.

  B = arctan(28.2/45.8) ≈ 31.621°

The measure of angle B is about 31.6°.

Answers

There's no convincing evidence at 0.05 significance level that this brand of toilet paper will require less than 26 squares.

What is a significance level?

A significance level simply means is the probability that an event has occured by chance.

In this case, there's convincing evidence at 0.05 significance level that this brand of toilet paper will require less than 26 squares to absorb 1/4 cup of water. Therefore, we fail to reject the null hypothesis.

A type of error that may have been made is type II error. This is the non rejection if the null hypothesis when it's false.

Draw a line on y=-2 and reflect the dot on the other side. The x doesn’t change, only y changes. So only option is (2,1).

When reflecting across the y axis the x value remains the same.

The reflection is at y -2, from -2 to the location of z (-5) is a difference of 3 units.

For the function f(x)= √x-6 +1, find the inverse function.

Answers

Answer:

f^(-1) (x) = (x-1)²+6    x≥6

Step-by-step explanation:

y=√(x-6) +1 original for the inverse x and y switch places because you are rflecting the function over the line y=x

y=√(x-6) +1 now the job is solve for y by using inverse operations. Think about undoing the equation.

x-1=√(y-6) subtract 1

(x-1)²=y-6 square both sides of the equation

(x-1)²+6=y add 6 to both sides

x≥6 because we are only using real numbers and if x is less than 6 you get a negative number under the square root sign.

How old is Kevin?

Answers

Answer:

:)

Step-by-step explanation:

Kevin = 4d  Kevin is 4 times as old as Daniel

Kevin = d + 6  Kevin is 6 years older than Daniel

4d = d + 6 They both equal K, so they are equal

3d = 6 subtracts D from both sides

d=6/3 = 2

If Daniel is 2 then Kevin is 4x2=8

If Daniel is 2 then Kevin is 2+6 = 8

Kevin is 8

Daniel is 2

In 1918, warring nations made peace after four years of "The Great War," now referred to as World War I. The United States retreated somewhat from global politics. Instead, the country focused on its own economic and technologic growth. The 1920s were a prosperous time for many Americans. The economy was booming, and many people made a lot of money. The decade is commonly known as the Roaring Twenties. People focused on having fun, spending time at cinemas and jazz clubs. Consumerism was on the rise. For the first time, factories built new products like cars and telephones for a wide market. With newfound wealth, people were able to buy these luxury items. Though the economy was doing well, mostly managers and business owners profited. Workers were not always so lucky. The gap between the rich and the poor grew. Those who still could not afford fancy new consumer products bought on credit. They took out loans on the promise that they would pay back the money they borrowed. Many people also borrowed money to invest in the stock market. They bought shares of businesses in order to make a profit if the company had success. All this borrowing meant that people saved very little and spent money that they ultimately did not have.
