C 6
D 7​

Answer:

8. B

9. A

10. C

11. B

Step-by-step explanation:

8. you factor the bottom equation and get that 1/2 and -2 are the roots

9. I would put none of the above, but that's not a choice, so the second most convincing is A

10.

11.

you can do the rest :)

Answer:

$12.05

Step-by-step explanation:

217 divides by 18 is 12.05

Answer:

x, x, -3, 2x cannot be an arithmetic sequence

Step-by-step explanation:

an arithmetic sequence has a constant difference between subsequent elements. That means

x - x = -3 - x = 2x - (-3)

0 = -3 - x = 2x + 3

and we get:

x = -3    ;     from 0 = -3 - x

and

x = -3/2    ; from 0 = 2x + 3

so there is no solution.

Answer:

D. Patel found the incorrect quotient and checked his work using multiplication incorrectly.

Step-by-step explanation:

The dividend is  the divisor is  Divide the dividend by the divisor (division by fraction means multiplication by its reciprocal):

so the quotient is 48, not

To check the answer, Patel has to multiply the quotient by the divisor to get the dividend. Check answer:

Hence, Patel found the incorrect quotient and checked his work using multiplication incorrectly.

Answer: reject the null hypothesis

Explanation:

If the p-value is smaller than the significance level alpha, then we reject the null. You can think of the p-value being the probability that the null is correct. If the p-value is below a certain threshold (the significance level), then we can be fairly confident that rejecting the null is a good decision.

Your teacher or textbook might have brought up the phrase "If the p-value is low, then the null must go" as a way to help remember this rule. If the alpha level isn't stated, then usually it defaults to 0.05

Answer:

y=3/5x+2

Step-by-step explanation:

I calculate

The answer *SHOULD* be 8.95$.

Step-by-step explanation:

So we do 6 x 0.45 because we are doing 6 apples times 45 cents which is 0.45 .

So 6 x 0.45 = 2.70$

Then , we don't do too much for the bananas due to the fact it is only 1 bunch so if 1 bunch is 1.00$ and they only got **1 bunch** it is automatically 1.00$.

Upon this, we do 7 x 0.57 . The 7 representing the pears and the 0.57 representing the 0.57 cents.

7 x 0.57 = 3.99$

Finally, we do 3 x 0.42. The 3 representing the oranges and the 0.42 representing 42 cents each.

3 x 0.42 = 1.26

2) Monique has 15 oranges, 9 peaches, and 18 pears. She wants to put all of the fruit into decorative baskets. Each basket must have the.

Step-by-step explanation:

Step-by-step explanation:

4x + 15y = 17

15y = 17 - 4x

y = (17 - 4x)/15

-x + 5y = -13

-x + 5(17 - 4x)/15 = -13

-x + (17 - 4x)/3 = -13

-x - 4x/3 = -13 - 17/3

-7x/3 = -56/3

7x = 56

x = 56/7

x = 8

y = (17 - 4x)/15

y = (17 - 4.8)/15

y = (17 - 32)/15

y = -15/15

y = -1

Answer:

y = 2/3x + 2

Step-by-step explanation:

3x + 2y = 8

2y = -3x + 8

y = -3/2x + 4

Slope : -3/2

Slope of the perpendicular line: 2/3 (slope of the perpendicular line is opposite reciprocal)

Point (3,4)

y-intercept = 4 - (2/3)(3) = 4 - 2 = 2

Answer:

2700

Step-by-step explanation:

Perimeter of rectangle= 2(length +breadth)

2(length +breadth)= 210

length +breadth= 210 ÷2

length +breadth= 105

Since the length of the rectangle is usually taken to be the longer side of the rectangle,

length: breadth= 4: 3

[tex] \frac{length}{breadth} = \frac{4}{3} [/tex]

[tex]length = \frac{4}{3} (breadth)[/tex]

[tex] \frac{4}{3} (breadth) + breadth = 105[/tex]

[tex] \frac{7}{3} (breadth) = 105[/tex]

breadth

[tex] = 105 \div \frac{7}{3} [/tex]

[tex] = 10 5\times \frac{3}{7} [/tex]

= 45

length +breadth= 105

length +45= 105

length

= 105 -45

= 60

Area of rectangle

= length ×breadth

= 45 ×60

= 2700

Answer:

38.4º

Step-by-step explanation:

Use Law of Cosines

c² = a² + b² - 2ab*cosC

12² = 17² + 19² - 2(17)(19)*CosC

Simplify

144 = 289 + 361 - 646 * cosC

144 = 650 - 646 * cosC

Subtract 650 from both sides

-506= -646 * cosC

Divide both sides by -646

0.7832817337 = cosC

Take the arcsin of 0.7832817337

38.4º = C

---------------------------------

Cheaters Solution!!!

Instead of doing the math you could think it through.

Since FD is less than 17

∠E must be less than 45º

So the answer must be A. 38.4º

Answer:

Slope = -4

Step-by-step explanation:

Given coordinates,

→ x1 = 2, y1 = -4

→ x2 = -1, y2 = 8

Now we have to,

→ Find the required slope of the line.

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Then the required slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (8 - (-4))/(-1 - 2)

→ m = (8 + 4)/-3

→ m = 12/(-3)

→ m = -12/3

→ [ m = -4 ]

Therefore, the value of m is -4.

Answer:

[tex]\Large \boxed{\sf Slope =-4}[/tex]

Step-by-step explanation:

The slope of a line is given by the following formula : [tex]\sf m=\dfrac{y_B-y_A}{x_B-x_A}[/tex] where [tex]\sf x_A[/tex] and [tex]\sf y_A[/tex]  are the coordinates of A (same for B).

Given :

Let's calculate the slope with the previous formula :

[tex]\sf m=\frac{8-(-4)}{-1-2} \\\sf m=\frac{8+4}{-3}\\ \sf m=-\frac{12}{3} \\\boxed{\sf m=-4}[/tex]

Answer:

$300 is the total cost for both kinds of paint

Step-by-step explanation:

1) Start by breaking down the problem so it was more simple

- Red paint is $35 per gallon; blue is $39 per gallon

2) Since it is by gallon, you will multiply the number of gallons by the cost for each to get the total cost of each

- 35 * 3 = $105 for 3 gallons of red paint

- 39 * 5 = $195 for 5 gallons of blue paint

3) Total cost together; you will add the total cost of red and blue paint together

- 105 + 195 = $300
