Answer:

8-inch pizza

Step-by-step explanation:

Answer:

A 16-inch pizza is the better deal, because its twice the size of the 8-inch and you would have to buy two to equal a 16-inch, but it would cost more. So a 16-inch would be a better deal.

Answer:

[tex]\frac{7}{9}[/tex] of a mile per hour

0.77777778 of a mile per hour

Step-by-step explanation:

[tex]\frac{y}{14} :\frac{1}{18}[/tex]

y · 18 = 1 · 14

18y = 14

18y ÷ 18 = 14 ÷ 18

[tex]y=\frac{7}{9}[/tex]

Answer: 1.28571428571

Step-by-step explanation: You divide the hours by miles

5 marbles.

We first need to find how many marbles we have in total.

8 marbles * 5 boys = 40 marbles.

These 40 marbles will now be divided by 8, since we are taking the total amount of marbles we have and separating them into 8 different piles.

40/8 = 5

There will be 5 marbles in each heap.

Answer:

Step-by-step explanation:

Remark

The two angles with x in them are = 90 degrees. That's because this is a right angle triangle.

Equation

x^2 + 10x + 115 = 90               Subtract 90 from both sides

Solution for x

x^2 + 10x + 115 - 90 = 0

x^2 + 10x + 25 = 0

Factor

(x + 5)(x + 5) = 0

x = - 5

Angle C

C = 10x + 115

C = 10*-5 + 115

C = -50 + 115

C = 65

Angle A (which you don't need)

x^2 = (-5)^2

x^2 = A = 25

Find BC

Cos(C) = adjacent / hypotenuse

Cos(65) =0.4226

AC = hypotenuse = 65

0.4226 = adjacent / 44   Multiply both sides by 44

44 * 0.4226 = adjacent

adjacent = 18.6 to three places.

Answer:

260 miles

Step-by-step explanation:

set up a proportion:

6.5/d = 1/40

cross-multiply:

d = 40(6.5) which equals 260 miles

Answer:

[tex]110\ in^2[/tex]

Step-by-step explanation:

[tex]1)\ A_1 = b * h_1 = 10 * 8 = 80\ in^2[/tex]

[tex]2)\ A_2 = \frac{b*h_2}{2} = \frac{10*(14-8)}{2} = \frac{10*6}{2} = \frac{60}{2} = 30\ in^2[/tex]

[tex]3)\ A = A_1 + A_2 = 80 + 30\ in^2 = 110\ in^2[/tex]

Answer: x = 10 OR x = 4.

Step-by-step explanation: If x = 10 or 4 then the last step of the equation will always be multiplying by 0 which equates to 0 as well.

if x = 10

(10-10)(10-4) -> (0)(6) -> 0 x 6 = 0

if x = 4

(4-10)(4-4) -> (-6)(0) -> -6 x 0 = 0

Answer:

Answer:

3^3 which is = 27

Step-by-step explanation:

When multiplying exponents with the same base, you just add the exponents and keep the same base.

Answer:

3^7 * (1/3)^4 because a^(-n) = (1/a)^n

Step-by-step explanation:

because a^(-n) = (1/a)^n

Answer:

the 1st option is false; there is no 'addition' sign

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

You have the opposite side given and the adjacent side. That means you will use the tangent.

Tan(theta) = opposite / adjacent

opposite = 6

adjacent = 3.5

Tan(theta) = 6 / 3.5

Tan(theta) = 1.714

Tan-1(1.714) = 59.74

when you get an answer over 1 from the division, you know that the angle is over 45 degrees.

Answer:

  M R T V B K

Step-by-step explanation:

From left to right the solutions are ...

__

B: equating expressions for y

  -2x = x -3   ⇒   3 = 3x   ⇒   x = 1

R: given

  x = -2

V: filling in for y

  4x +5(2) = 10   ⇒   x = 0

T: subtracting the first from twice the second

  2(3x +y) -(-3x +2y) = 2(0) -9   ⇒   9x = -9   ⇒   x = -1

K: adding the two equations

  (2x +y) +(3x -y) = (7) +(3)   ⇒   5x = 10   ⇒   x = 2

M: equating expressions for y

  x -2 = 1/3x -6   ⇒   2/3x = -4   ⇒   x = -6

__

The solutions in order least to greatest are ...

  -6 (M), -2 (R), -1 (T), 0 (V), 1 (B), 2(K)

Additional comment

In several cases, there are variables and constants on both sides of the equal sign. The solution method is to identify the smallest variable coefficient, and add the opposite of that term. Also added at the same time is the opposite of the constant term on the other side of the equal sign. The net effect is to put the variable on one side and the constant on the other side. Then the equation is divided by the coefficient of the variable.

For example, in the first equation, -2x is the variable term with the smallest coefficient. -3 is the constant on the other side of the equation. To get from the initial expression to the next, we add 2x+3 to both sides of the equation.

H. 30%

Step-by-step explanation:

[tex]\frac{100}{y}: \frac{300}{390}[/tex]

y · 300 = 100 · 390

300y = 39000

300y ÷ 300 = 39000 ÷ 300

y = 130

130% - 100% = 30%

Answer:

The probability of rolling an even number would be [tex]\frac{1}{2}[/tex] or 50%.

Step-by-step explanation:

A standard number cube has 6 sides that features numbers 1 to 6 on each side. Since there are three even numbers (2, 4, 6) total on the sides of the number cube, that means the theoretical probability of rolling an even number would be [tex]\frac{3}{6}[/tex], which simplifies to [tex]\frac{1}{2}[/tex] or 50%.

Answer:

x = 20 units

Step-by-step explanation:

∆KJL is a 30° - 60° - 90° triangle which means that side opposite of 30° is x, side opposite of 60° is x√3, and side opposite of 90° is 2x.

Since side opposite of 90° is 40√2 which is 2x and x is the side opposite of 30° (JL).

2x = 40√2 → 2x ÷ 2 = 40√2 ÷ 2 → x = 20√2.

∆JML is a 45° - 45° - 90° triangle which means that sides opposite of 45° are x and 90° is x√2.

Since side JL is also the side opposite of 90° and the sides opposite of 45° are the value x,

20√2 = x√2 → 20√2 ÷ √2 = x√2 ÷ √2 → 20 = x →

x = 20.
