Answer: =−4[tex]x^{8}[/tex]+25

The 8 is an exponent

Step-by-step explanation:

(5−2x4)(5+2x)

=(5+−2)(5+2)

=(5)(5)+(5)(2[tex]x^{4}[/tex])+(−2

=25+10[tex]x^{4}[/tex]−10

Answer:

r = 11.94

Step-by-step explanation:

Circumference Formula:

C = 2πr

75 = 2(3.14)r

75 = 6.28r

r = 75/6.28

r = 11.94

Step-by-step explanation:

Answer:

x = length of sitcoms = 21 minutes

y = length of dramas = 42 minutes

Step-by-step explanation:

Let

x = length of sitcoms

y = length of dramas

6x + 6y = 372 (1)

2x + 6y = 288 (2)

Subtract (2) from (1) to eliminate y

6x - 2x = 372 - 288

4x = 84

x = 84/4

x = 21

Substitute x = 21 into (1)

6x + 6y = 372

6(21) + 6y = 372

126 + 6y = 372

6y = 372 - 126

6y = 246

y = 246/6

y = 41

x = length of sitcoms = 21 minutes

y = length of dramas = 42 minutes

Answer:

Charlene earns $700 per week

Kristi earns $550 per week

Sascha earns $800 per week

Step-by-step explanation:

Since Kristi earns 150 less than Charlene which is 100 less than Sascha, this is equal to the value of Sascha minus 250. We put this in the equation as s-250.

Together, they all earn $2050, so we must equal this to Charlene's value k+150, plus Kristi's value k, plus Sascha's value s.

k+150+k+s=2050

The next step here is to put the variables on one side and to put the numeric values on the other.

2k+s=1900

Like we said before, Kristi's value is equal to s-250, so we would replace k with that expression.

2(s-250)+s=1900

2s-500+s=1900

3s=2400

s= 800

We now have Sandra's weekly pay, which we can use to find the others' pay.

c= s-100

c= 800-100

c= 700

k= c-150

k= 700-150

k= 550

Step-by-step explanation:

Answer:

56 degrees

Step-by-step explanation:

just cause

Answer:

56 degrees

Step-by-step explanation:

the total degrees in a quadrilateral is 360

and in a trapezoid the top two angles measure the same and the bottom two measure the same

so since one of the top angles is 124 the one beside it is too

add 124 and 124 you get 248

then subtract it from 360 and you get 112

divide 112 by 2 and you get 56 which is the angle of x

I believe this is correct! Good luck :)

Theoretical Probability:

P(rolling a 2) = 16.7%

P(rolling a 5) = 16.7%

P(rolling 2 or 3) = 33.4%

P(greater than 4) = 33.4%

P(3 or less) = 50.1%

Experimental Probability:

P(rolling a 2) = 20%

P(rolling a 5) = 6%

P(rolling 2 or 3) = 36%

P(greater than 4) = 24%

P(3 or less) = 54%

Explanation:

Theoretical probability can be calculated based on the idea that each of the six numbers on the die has an equal chance of being rolled and all numbers' probabilities total to 100%. Experimental probability is based on the outcomes of your experiment (rolling the dice yourself).

When finding the probability of rolling a number or another number (for example, rolling a 2 or 3), just add the probabilities together (You rolled 2 ten times and 3 eight times, so the experimental probability of rolling a 2 or 3 is 18/50 = 36%)

Answer:

Step-by-step explanation:

Midsegment means it's the middle, or half-way .  It chops the sides into even parts.  The line that's the midsegment is going to be parallel to the base and half the size of the base.  In other words, double the midsegment and that's equal to the base.  Then, just solve for x.

Answer:

the pool would be 10 cm by 5 cm

Answer:

The scale drawing would be 10 centimeters by 5 centimeters

Step-by-step explanation:

It's 1:5

If you multiply each side by 10, you get 10:50, that shows it'd be 10cm for the length and then you do the same for the width, 5:25, to get 5cm.

Answer:

x=-6

Step-by-step explanation:

The only thing to do is to transpose 4 and it will become negative,so-2-4=-6

Answer:

X = -6

Step-by-step explanation:

The equation is x + 4 = -2. Make the (+4) to cross over the equal sign which makes a new equation :- x = -2 - 4

Work out the new equation:-

x = -2 - 4

NOTE: -2 - 4 = -6

Therefore x = -6

Answer: [tex]\$ 70[/tex]

Step-by-step explanation:

Given

Hester get a fixed amount and an additional $15 for an extended warranty

Suppose x is the amount of fixed amount

for 15 television sale, the price is $1275

Thus, we can write

[tex]\Rightarrow 15(x+15)=1275\\\Rightarrow x+15=85\\\Rightarrow x=\$70[/tex]

Therefore, the fixed amount of television is [tex]\$70[/tex]

Answer:

y - 8

Step-by-step explanation:

She is 8 years younger so you'd subtract eight from her sister's age.

Find the volume of each and then divide the volume of the box by the volume of the cube.

Volume of box: 8 1/2 x 5 1/2 x 2 1/2 = 116 7/8 cubic inches.

Volume of cube = 1/2^3 = 1/8 cubic inches

Number of cubes: 116 7/8 / 1/8 = 935 cubes.
