Reasoning The spinner is divided into eight

Answer:

Because the 8 parts are equal, there is an equal chance of landing on each part. The chance of landing on any part is 1/8. This means that it would be impossible to predict with certainty which section will be landed on, because there is an equal chance of each.

Does that help?

Step-by-step explanation:

The probability of landing on each of the eight parts is equal since the 8 parts are equal. Landing on any part has an 8 percent chance. The odds of landing on one of the sections are equal, so it is impossible to predict exactly where the ball will fall.

A market sells soup in 6-ounce cans and 12-ounce cans. On Tuesday, the market sold a total of 420 ounces of soup in 44 cans.
Vikki [24]

Answer:

The market sold 18 6-ounce cans of soup on Tuesday

Step-by-step explanation:

Let us solve the question

- The number of the 6-ounce cans is x

- The number of 12-ounce cans is y

- 6x + 12y = 420

→ Divide each term by 6 to simplify the equation

- x + 2y = 70 ⇒ (1)

- x + y = 44 ⇒ (2)

→ Subtract equation (2) from equation (1)

- (x - x) + (2y - y) = (70 - 44)

- 0 + y = 26

- y = 26

Substitute the value of y in equation (2) to find the value of x

-x + 26 = 44

→ Subtract 26 from both sides

- x + 26 - 26 = 44 - 26

- x = 18

- x represents the number of the 6-ounce cans

- The market sold 18 6-ounce cans of soup on Tuesday

Answer:


Step-by-step explanation:

1. 2x - 1 < x + 3

Subtract x and add 1 to both sides

2x - 1 - x + 1 < x + 3 - x + 1

x < 4

2. 5x - 1 > 6 - 2x

Add 1 and 2x to both sides

5x - 1 + 1  + 2x > 6 - 2x + 1 + 2x

7x > 7

Divide both sides by 7

7x/7 > 7/7

x > 1

3. x - 5 < 0

Add 5 to both sides

x-5 + 5 < 0 + 5

x < 5

vineet solved a system of equations by substitution. in his work, he substituted an expression for one of the variables and solv
seropon [69]
Answer b: the system of equations does not have a solution

Suppose the systems consits of two first grade equations with two varaibles. If the two equations are parallel you would obtaing a result like Vinnet.

This is an example:

x = y + 1

7x = 7y +  9

substitue to get:

7(y+1) = 7y +9
7y + 7 = 7y + 9
7=9

There is not mistake, the system has no solutions, because the two equations represent parallel lines, which do no intercept one to each other.

davidson family wants to expand its rectangular patio, which currently measures 15 ft by 12 ft. they want to extend the length a
kumpel [21]
<h2>Answer</h2>

(12+x)(15+x)=160+15*12

Which simplifies to:

x^2+27x-160=0

<h2>Explanation</h2>

Let x the number of feet they are going to expand the width and length of the patio. So the new width of the patio will be 12+x and the new length 15+x.

Remember that the area of a rectangle is <u>width times length</u>, so the length of our expanded patio will be (12+x)(15+x). But, we also know form our problem that they want to increase the total area of the patio by 160 ft2. The actual area of the patio is (15ft)(12ft), so the expanded area of the patio will be 160ft^2+(15ft*12ft).

Now we can equate the expanded area of the patio and simplify:

(12+x)(15+x)=160+15*12

180+12x+15x+x^2=160+180

180+27x+x^2=340

x^2+27x-160=0

If you apply the changes below to the quadratic parent function, f(x) = x2, what is the equation of the new function? Shift 3 un
Alex17521 [72]
To apply the changes to the equation of a vertical stretch of 4 and a translation of 3 units to the right, as well as the correct answer would be choice B.

The reason for this is when you apply a vertical stretch, because it changes the y-values (which causes it to vertically stretch or appear skinnier when graphed), you would multiply 4 to f(x) which would look like 4x^2.

Then, since you have a reflection over the x-axis, you must multiply a -1 to f(x) to reflect it over the x-axis which would result in -4x^2.

Finally, it also asks to shift the graph right 3 which by moving it right, you change the x values meaning you will perform f(x-3) to achieve this (subtract the value from x when you move right, and add the value to x when you move left).

This therefore results in your answer, the new graph would be
g(x)= -4(x-3)^2 or choice B.
