A. - 96
B. -16
C. 16
D. -32/3
E. 32/3

Answer:

I'm a bit rusty. But try 58x +21

Hope I helped you.

Answer:

Step-by-step explanation:

Any polynomial can only have as many zeros as is the highest exponent at x.

A cubic polynomial it's:  ax³+bx²+cx+d. The highest exponent at x is 3 so it is the largest number of its zeros.

49.5 texts

Step-by-step explanation:

The total number of students is

11+21+33+23+12 = 100

The middle is 50

150 is in the middle group

The median will be between 40 -59

The best estimate for the median is to add the 40+59 and divide by 2

(40+59)/2 = 99/2 = 49.5 texts

Answer:

8:5

Step-by-step explanation:

there are 25 girls, and 40 boys, so you find the common factor between them,which is 5 and divide each number by 5.

25/5=5 girls

40/5=8 boys

so the ratio of boys to girls is 8:5

Answer:

Each flower type area ratio = 14 ft²

Step-by-step explanation:

Given:

Total area = 70 ft²

Total equal varieties = 5

Find:

Each flower type area ratio

Computation:

There is 5 equal part of land

So,

Ratio = 1:1:1:1:1

Assume each part cover = x

So

Total area = 5x

5x  = 70 ft²

x = 14 ft²

Each flower type area ratio = 14 ft²

Answer: (-5,0)

Step-by-step explanation:

-4x + 5y = 20   the x intercept is when y is zero so input zero into the equation and solve for x.

-4x + 5(0) = 20

-4x = 20

x = -5  

Answer:

t = 0.06c

Step-by-step explanation:

Given the following :

Percentage sales tax on items = 6%

Cost of item = c

Amount of sales tax on item = t

Amount of sales tax is the product of the sales tax percentage and the cost of item purchased

Hence, Amount of sales tax;

t = 6% × cost of item (c)

t = 0.06 × c

t = 0.06c

Answer:

I would assume it would be 12h+6k

Answer:

Step-by-step explanation:

Use distributive property

a(b+c) = a*b + a*c

3(4h + 2k) = 3*4h + 3 *2k

                  = 12h + 6k

Answer:

To convert binary into decimal, multiply each binary digit with a power of 2 corresponding to its position.

So for example 1010 would be 1·2³ + 0·2² + 1·2¹ + 0·2⁰ = 8+2 = 10 in decimal.

now you can calculate the answers yourself!

To convert decimal into binary, you can use the following approach:

Write down the answer from right to left

A. if your number is odd, write down a 1, if it is even, write a 0

B. divide the number by 2 and round down, ie. discard any decimals (e.g., 7 / 2 = 3)

C. repeat step A until your number is 0.

example:

18 -> write down 0

18/2 = 9 -> write down 1

9/2 = 4 -> write down 0

4/2 = 2 -> write down 0

2/2 = 1 -> write down 1

1/2 = 0 finished

The result is 10010.

Step-by-step explanation: The 9 in 857.9 differs from the value of 9 in 798.21 because in 857.9, the 9 is in the tenths place, while in 798.21, it is in the tens place.

If two parallel lines are cut by a transversal,

then alternate interior angles are congruent.

Since one alternate interior angle measures 60 degrees,

the other alternate interior angle must also measure 60 degrees.

Answer:

Alan buys 12.05 ounces of sour patch kids candy in all.

Step-by-step explanation:

We are given that Alan buys 5.3 ounces of sour patch kids candy. After sharing with his friends he returns to buy an additional 6.75 ounces.

And we have to find the total ounces he buys in all.

As we know that for finding the total quantity or amount, we will use addition for calculating it.

Firstly, Alan buys = 5.3 ounces of sour patch kids candy

Additional ounces of sour patch kids candy Alan buys = 6.75

So, the total ounces of sour patch kids candy he buys in all = 5.3 + 6.75

                                                                                                   = 12.05 ounces

Hence, he buys 12.05 ounces in all.

Domain is   [tex]0 \le x \le 12[/tex]

Range is [tex]0 \le y \le 900[/tex]

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

Explanation:

The smallest x can be is x = 0. The largest x can be is x = 12. This is shown as the left-most and right-most values of the graph. We could have x be anything between 0 and 12, including both endpoints, so we say the domain is [tex]0 \le x \le 12[/tex]. Recall the domain is the set of all allowed x inputs of a function.

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

The range is the set of all possible y outputs. The smallest y output possible is y = 0, and the largest is y = 900. The range is therefore [tex]0 \le y \le 900[/tex] meaning y is between 0 and 900, including both endpoints.

Both domain and range endpoints happen to be at the x and y intercepts. This won't always be the case.

Answer:

2 real number solutions.

Step-by-step explanation:

You check the value of the discriminant b^2 - 4ac.

Here it = (-10)^2 - 4*2* 6)

= 100 - 48

= 52. (Positive)

This means that it has 2 real number solutions.

If the discriminant = 0 it has one real number solution and if negative it has no real number solutions.

Answer:

i think its 2 real number

Answer:

[tex]\frac{214}{99}[/tex]

Step-by-step explanation:

We require to create 2 equations with the repeating digits after the decimal point. Then by subtracting them we eliminate the repeating part.

let x = 2.1616.... → (1)) ← multiply both sides by 100

100x = 216.1616..... → (2)

Subtract (1) from (2)

99x = 214 ( divide both sides by 99 )

x = [tex]\frac{214}{99}[/tex]

Answer:

(x+3)(2x+3)

Step-by-step explanation:

Factor:

2x^2+9x+9

=(2x+3)(x+3)

Answer:

(x + 3)(2x + 3)

Step-by-step explanation:

Sum = 9

Product = 2*9 = 18

Factors = 6 ,3

2x² + 9x + 9 = 2x² + 6x + 3x + 3 * 3

                    = 2x ( x + 3) + 3( x + 3)

                      = (x +3)(2x + 3)                

Answer:

a = 80

b = 310

c = 96

Step-by-step explanation:

1)

20 + a + a = 180

2a + 20 = 180

2a = 160

a = 80

2)

180 - 65 - 65 + b = 360

b + 50 = 360

b = 310

3)

52 + c + 32 = 180

c + 84 = 180

c = 96

Answer:

$15

Step-by-step explanation:

Let's start by figuring out how much 1 cup of oil costs.

12 cups of oil is 36$

Let's set up a proportion.

12/36=1/x

Cross Multiply

12x=36

Divide both sides by 12.

x=3

1 cup of oil is $3.

Dinesh makes 5 batches of hummus, and each batch requires 1 cup of oil.

5*1=5

This means he needs 5 cups of oil.

5*3=15

He used $15 worth of oil in the 5 batches of his recipe.

However, since it is impossible to buy 5/12 bottles of oil, he would have needed to spend $36.

Answer:

120, 68, 72, 36, 32, 41, 31 (Left to right, top to bottom)

Step-by-step explanation:

When looking at the tree, we start from left to right. That means the numbers on the left are larger and get smaller as we move to the right. The very first one on the left is 120 since there are 120 in the theater.

We know that 72 are female so we can put that in the lower bubble of the second column. From this information, we can find the # of males.

140-72=68. We can put 68 in the upper bubble of the second row.

We can first finish the male side with ice cream. We know 36 purchased ice cream which goes in the top bubble on the right. Now we subtract to find the remainder. 68-36=32. 32 goes right below 36

Now we go to the female side. 41 bought ice cream. This goes in the one 3rd down on the right. 72-41=31. 31 goes right  below 41

Answer:

There are 120 people (both male and female)

48 male =  36 bought ice cream

                  12 without an ice cream

72 female = 41 bought ice cream

                    31 without ice cream

lets say for the first transformation x=1 and y=2

the transformation results in quadrant 2 (originating in quadrant 1) telling us it was a 90° counter-clockwise turn

for the second transformation we can let x=3 and y=4

transformation 2 results in quadrant 3 (originating in quadrant 1) telling us it was a 180° counter-clockwise turn
