Answer:

A

Step-by-step explanation:

A mode is the value that appears most frequently in the data set because there is not more than one of any number the data set has no mode.

Answer:

Step-by-step explanation:

45n = (9 x 25) + 4 + (2x4)

45n = 225 + 4 + 8

45n/45 = 237/45

n = 5.26666...7

exactly 5.26666...7 buses would be needed.

realistically 6 buses are needed, as you cannot have part of a bus operating like a normal one

the exact answer can be classified as a rational number as it can represent a fraction.

Answer:

58

Step-by-step explanation:

90+32= 122

180-122=58

Answer:

X = 122°

Step-by-step explanation:

A triangle has 180 degrees total in it. You need the degree next to the x in order to solve.

32° + 90° = 122°

180° - 122° = 58°

The line is 180°.

180° - 58° = 122°

So x - 122°

Answer: f(x-2) which is choice A.

The blue f(x) curve is shifted 2 units to the right to get the red g(x) dashed curve.

============================================================

Explanation:

For now, ignore the red dashed curve g(x). Imagine that the blue curve f(x) is fixed in place. If we shifted the xy axis to the left 2 units, then this gives the illusion the blue curve is moving even though the curve is fixed in place.

The operation "shift xy axis 2 units to the left" means each x input is 2 units smaller. So each x input is now x-2.

Therefore, going from f(x) to f(x-2) will shift the blue curve 2 units to the right to land perfectly on the red dashed g(x) curve.

Answer:

n = -4

Step-by-step explanation:

-32=8n

Divide each side by 8

-32/8 = 8n/8

-4 = n

- 32 = 8n

Cross multiplying we get

n = -32/8

n = -4

Answer:

47 degrees

Step-by-step explanation:

The number system goes from negative numbers, to zero, to positive numbers. To get to zero from a negative number, you add the positive version of your number to get to zero. In this case we have to add 17 to get to zero. So our answer is 30+17. Because once we get to zero, we know there is 30 degress to get to the temp in Middlesink. So it is a 47 degree change.

Answer:

6.68

Step-by-step explanation:

To round 6.675 to the nearest hundredth consider the thousandths’ value of 6.675, which is 5. Therefore, the hundredths value of 6.675 increases by 1 to 8.

6.675 rounded to the nearest hundredth = 6.68

Answer: 1232 pieces

Work Shown:

1 bag = 7 apples

22 bags = 22*7 = 154 apples

So we have 154 apples to work with in total.

Each of those apples is cut into 8 pieces, giving us 8*154 = 1232 pieces

We can write it as one single calculation to say 22*7*8 = 1232

Answer:

13/50

Step-by-step explanation:

Answer:

26/100

Method:

Fractions are much like percents, as they are both out of 100. The 26% is 26%/100% (26/100)

The length that can be cut off from the three given pieces of wood equally to form a right triangle is 5 cm

Given parameters:

dimension of the three pieces of wood = 20 cm, 41 cm and 44 cm

To find:

let the length that is cut off from each of the wood = y

From Pythagoras theorem, we will have the following equation.

[tex](44-y)^2 = (20-y)^2 + (41-y)^2\\\\expand \ the \ equation \ as \ follows;\\\\1936 - 88y + y^2 = 400 - 40y + y^2 + 1681 - 82y + y^2\\\\simplify \ by \ collecting \ similar \ terms \ together\\\\(1936 - 400- 1681) + (-88y + 40y+ 82y) + (y^2 - 2y^2) = 0\\\\-145 +34y - y^2 = 0\\\\multiply \ through \ by \ (-1)\\\\y^2-34y + 145 = 0\\\\factorize \ the \ above \ quadratic\ equation\\\\y^2 -5y - 29y + 145 = 0\\\\y(y - 5) -29(y - 5)=0 \\\\(y -5)(y-29) = 0\\\\y = 5 \ \ \ or \ \ \ \ y = 29[/tex]

Since the least measurement of one of the pieces of the wood is 20 cm, we cannot cut off 29 cm.

Thus, the highest amount we can cut off equally is 5 cm

Answer: x= -189, y =252

Step-by-step explanation:

Let the first number be x and second number be y

so

x + y = 63

x = 63-y

now

1/9 of x + 1/6 of y = 21

x/9 + y/6 = 21

substituting x's value from equation i

(63-y)/9 + y/6 = 21

(378-6y+9y)/54 = 21

378+3y = 1134

3y = 1134-378

so, 3y = 756

so, y = 756/3

so, y = 252

now

x = 63-252

so, x = -189

Answer:

(-4,-6)

Step-by-step explanation:

3x-4y=12

5x-2y=-8

multiply #2 by "-2"

3x-4y=12

-10x-4y=16

add two equations

-7 x = 28

x= -4

plug in -4 to equation (1 or 2)

-12 - 4y = 12

-4y = 24

y = -6

(-4,-6)

Answer:

x = -4.

y = -6.

Step-by-step explanation:

3x-4y=12

5x-2y=-8       Multiply this equation by 2:

10x-4y = -16    Subtract this from the first equation:

-7x  = 28

x = -4

Substitute thin in equation 2:

3*(-4)  - 4y = 12

-12 - 4y = 12

-4y = 24

y = -6.
