Answer:

f(6)=24

Step-by-step explanation:

[tex]f(x) = 2x^2 - 7x - 6\\f(6) = 2(6)^2 - 7(6) - 6=2*36-42-6=24[/tex]

Answer:

f(6) = 24

Step-by-step explanation:

f(x) = 2x² – 7x – 6: f(6)

f(6) = 2(6)² - 7(6) - 6

= 2 × 36 - 42 - 6

= 72 - 48

f(6) = 24

Thus, f(6) = 24

Answer:

42% decrease

Step-by-step explanation:

To get the percent increase or decrease, subtract 450 by 261 to get 189. Then divide this by 450 to get 0.42. Multiply this by 100 to get a 42 percent decrease.

Step-by-step explanation:

75 x 8 = 600

Answer:

the answer is 600 silver paper clips

Step-by-step explanation:

So the question asks how many SILVER PAPER CLIPS are in 8 boxes. The questions adds 25 GOLD CLIPS just to throw you off. You do not do nothing with it, it just there to mess with your mind. Also it says 75 silver clips in EACH box and there are 8 boxes. So you multiply 75 with 8 and get 600 SILVER PAPER CLIPS

Answer: 950

Step-by-step explanation: x= original price

so we know that the desk cost x dollars and after 38% discount the desk was 589

589= discounted price= original price x-the 38%

589=x-0.38x=0.62 x

x=589/0.62=950

The original price of the desk is $950.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The original price = 100%

Selling price = $589

Discount = 38%

100% - 38% = 589

62% = $589

Multiply 100/62 on both sides.

100% = 100/62 x 589

100% = $950

Thus,

The original price of the desk is $950.

Answer:

the ratio of perimeter red to blue hexagon is 3/5

the ratio of the area of red to blue hexagon is 9/25

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Answer: $167.02

Step-by-step explanation:

Amount spent when there's discount

= $150.32

Discount = 10%

Since there's a discount of 10%, it means that (100% - 10%) = 90% of the value of the good was paid.

Let the original value be x.

Therefore, 90% of x = $150.32

90% × x = $150.32

0.9 × x = $150.32

0.9x = $150.32

x = $150.32/0.9

x = $167.02

The value is $167.02

Answer:

The correct answer is d.

Step-by-step explanation:

Let's solve each answer and see which one matches.

Note that in each case, you simply add or subtract from x inside the radical to move left or right respectively.  Similarly, just add or subtract to the full expression to move up or down respectively. Doing so we get:

a) [tex]f(x) = \sqrt[3]{x + 7} + 3[/tex]

b)[tex]f(x) = \sqrt[3]{x - 3} - 7[/tex]

c)[tex]f(x) = \sqrt[3]{x - 3} + 7[/tex]

d)[tex]f(x) = \sqrt[3]{x - 7} + 3[/tex]

So d is the correct answer.

Answer:

140 oranges

Step-by-step explanation:

From the Question, we know that the pyramid has 7 layers

The number of oranges in the first layer is = 1

Hence, the number of oranges in a pile is calculated as:

1² + 2² + 3² + 4² + 5² + 6² + 7²

= 1 + 4 + 9 + 16 + 25 + 36 + 49

= 140 oranges

Answer:

1, 5 and 6.

Step-by-step explanation:

The sides of this triangles has lengths in the ratio x : √3x : 2x where 2x is the hypotenuse.

When C = 30,  the side AB is the small leg  (=x).

When B = 90, the hypotenuse is  AC ( =2x).

When A =  60, the larger leg is BC (=√3x).

1.  AB = 4, BC = 4√3 :- Are possible legs.

5 AB = 7, AC = 14. :-  AB = small leg, AC = hypotenuse.

6. AB = 11, BC = 11√3:-   AB = small, BC = larger leg.

Answer:

$18.36

Step-by-step explanation:

In this question, we have to find the cost of the cake for the customer who orders a month early.

We know that the original price of the cake is $30.

We also know that there was a 28% discount and a 15% discount added to the purchase.

Remember, You don't add discount percentages together, you discount the prices separately.

Solve:

First, apply the 28% discount.

30 · 0.28 = 8.40

30 - 8.40 = 21.60

Now apply the 15% discount to the new price.

21.60 · 0.15 = 3.24

21.60 - 3.24 = $18.36

They needed to pay $18.36 for the cake.

Answer:

x = 7

Step-by-step explanation:

In a parallelogram the opposite angles are congruent, then

14x + 8 = 106 ( subtract 8 from both sides )

14x = 98 ( divide both sides by 14 )

x = 7

[tex]x=7[/tex]

Step-by-step explanation:

[tex]m∠ X= m∠V[/tex]

[tex]14x + 8 = 106[/tex]

[tex]14x = 106 - 8[/tex]

[tex]14x = 98[/tex]

[tex] \frac{14x}{14} = \frac{98}{14} [/tex]

[tex]x = 7[/tex]

to be sure

[tex]14x + 8 { = }^{?} 106[/tex]

[tex]14 \times 7 + 8 { = }^{?} 106[/tex]

[tex]98 + 8 { = }^{?} 106[/tex]

Answer:

0.75

Step-by-step explanation:

The complete question is attached below.

The dots on the numbers of the dot plot represent the number of boxes it took Vera to get all the prizes.

Therefore, the probability of getting all the prizes in 9 or fewer boxes is the sum of the number of times it took her to get 4 prizes in 9 boxes or fewer.

Hence:

P(x ≤ 9) = P(x = 4) + P(x = 5) + P(x = 6) + P(x = 7) + P(x = 8) + P(x =9)

P(x ≤ 9) = (4 / 36) + (6 / 36) + (3 / 36) + (4 / 36) + (4 / 36) + (6 / 36)

P(x ≤ 9) = 27 / 36

P(x ≤ 9) = 3 / 4 = 0.75
