Answer:

39.76

Step-by-step explanation:

8 x 8.3 = 66.4

2640/66.4 = ( when rounded to the nearest tenth) 39.76

Step-by-step explanation:

what happens, when we actually calculate the given fractions ?

after all, a fraction is always a division.

so,

1/3 = 0.3333333333...

1/25 = 0.04

1/5 = 0.2

1/4 = 0.25

aha !

1/4 is the correct answer.

Answer:

He had 31 points in the first round.

Step-by-step explanation:

Answer:

39-8= 31

Step-by-step explanation:

let the first round be x

second round =8

first round + the second round = 39

therefore, x+8=39

collect like terms

x= 39-8= 31.

so the answer is 31

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;

5 x 4 = 20

If a color is selected at random the probability would be

[tex]\frac{part}{whole}[/tex]

our part is 5

our whole is 20

so the probability would be;

[tex]\frac{5}{20}[/tex] or [tex]\frac{1}{4}[/tex] when reduced

Solving

Answer:

2147483648

Step-by-step explanation:

The pattern being used is x4.

8 x 4 = 32

32 x 4 = 128

128 x 4 = 512

512 x 4 = 2048

2048 x 4 = 8192

8192 x 4 = 32768

32768 x 4 = 131072

131072 x 4 = 524288

524288 x 4 = 2097152

2097152 x 4 = 8388608

8388608 x 4 = 33554432

33554432 x 4 = 134217728

134217728 x 4 = 536870912

536870912 x 4 = 2147483648

Hey there!

4 + 5x + 66 = x + 10

70 + 5x = x + 10

5x + 70 = x + 10

SUBTRACT x to BOTH SIDES

5x + 70 - x = x + 10 - x

5x + 70 - 1x = 1x + 10 - 1x

SIMPLIFY IT!
4x + 70 = 10

SUBTRACT 70 to BOTH SIDES

4x + 70 - 70 = 10 - 70

SIMPLIFY IT!
4x = -60

DIVIDE 4 to BOTH SIDES

4x/4 = -60/4

SIMPLIFY IT!
x = -60/4

x = -15

Therefore, your answer is: x = -15

Good luck on your assignment & enjoy your day!

Answer:

Step-by-step explanation:

Given :

#1 : Combine like terms on each side.

#2 : Subtract x from each side.

#3) Subtract 70 from each side.

#4) Divide 4 from each side.

Solution : x = -15

The inequality that represents the possible combinations of candy bars and  lollipops that he can buy is given by:

[tex]0.45x + 0.25y \leq 28[/tex]

The total price can be no more than $28, hence:

[tex]T \leq 28[/tex]

Each candy bar costs $0.45 and each lollipop costs $0.25. x is the number of candy bars and y of lollipops. Hence, the total price is given by:

T = 0.45x + 0.25y.

Hence, the inequality that models the situation is:

[tex]0.45x + 0.25y \leq 28[/tex]

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

1/3 (300000) = 100 000      80% of this = 80 000

2/5 (300000) = 120000    125% of this = 150 000    total so far = 230 000

Overall 10% profit would yield  300000(1.1) = 330 000

 the remaining land needs to sell for

    330 000 - 230000 =    100 000

Answer: A

Step-by-step explanation:

Answer:

[tex]A = 43.1\ cm^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area

[tex]A=\frac{1}{4}\sqrt{5(5+2\sqrt{5})}*a^2[/tex]

[tex]A=\frac{1}{4}\sqrt{5(5+2\sqrt{5})}*(5\ cm)^2[/tex]

[tex]A = \frac{1}{4}*6.8819*25\ cm^2[/tex]

[tex]A = 43.1\ cm^2[/tex]

Answer:  [tex]A = 43.1\ cm^2[/tex]

The correct choice of this question with the given polynomial is "The zeros are -2 and 8, because the factors of g are (x + 2) and (x - 8)". (Correct choice: H)

In this case we have a second order polynomial of the form x² - (r₁ + r₂) · x + r₁ · r₂, whose solution is (x - r₁) · (x - r₂) and where r₁ and r₂ are the roots of the polynomial, which can be real or complex numbers but never both according the fundamental theorem of algebra.

If we know that g(x) = x² - 6 · x - 16, then the factored form of the expression is g(x) = (x - 8) · (x + 2). Hence, the correct choice of this question with the given polynomial is "The zeros are -2 and 8, because the factors of g are (x + 2) and (x - 8)". [tex]\blacksquare[/tex]

Fractions are sometimes the same as dividing, for this case, that rule applies.

[tex]\frac{50}{6}\\\\\frac{11}{5}[/tex]

↑ These improper fractions translate to...

Answer:

1)  D. 8 2/6 hotdogs

2)  B. 2 1/5 cakes

Step-by-step explanation:

1) If she's dividing 50 hotdogs equally among 6 people, then you would divide 50 by 6 to find how many each person gets.
note: 50 ÷ 6 is the same as [tex]\frac{50}{6}[/tex].

[tex]\frac{50}{6}[/tex] =  [tex]8\frac{2}{6}[/tex]

6 can go into fifty 8 times, so there is a whole number of 8. There is 2/6 left over, so the final result is [tex]8\frac{2}{6}[/tex].

2) If Sako makes 11 cakes and wants to share it equally among 5 people, we can divide 11 by 5 to find how many each person gets.

[tex]\frac{11}{5} =2\frac{1}{5}[/tex]

5 can go into eleven 2 times, so there is a whole number of 2. There is 1/5 leftover, so the final result is [tex]2\frac{1}{5}[/tex].

Hence, the answers are D, and B.
