YOur math teacher gives you a worksheet that has 20 problems. She tells you choose 3/4 of the problems can you skip? If you get one third of the assigned problems done in class, how many problems do you have for homework?

Answer:

A foot is 12 inches and 4 is closer to 0 than 12 meaning 13 ft 4 in simplified is 13 ft

Step-by-step explanation:

total amount is $46.75 and if they split the cost it is $15.58

Let's solve your inequality step-by-step.

9−4(x+4)≤7+4(5x+7)

Step 1: Simplify both sides of the inequality.

−4x−7≤20x+35

Step 2: Subtract 20x from both sides.

−4x−7−20x≤20x+35−20x

−24x−7≤35

Step 3: Add 7 to both sides.

−24x−7+7≤35+7

−24x≤42

Step 4: Divide both sides by -24.

Answer:

B: 1/64

Step-by-step explanation:

2^3 = 8

8^(-2)=1/(8^2)=1/64

Note: Consider we need to find the vertices of the triangle A'B'C'

Given:

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.

Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).

To find:

The vertices of the triangle A'B'C'.

Solution:

If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then

[tex](x,y)\to (y,-x)[/tex]

Using this rule, we get

[tex]A(-3,6)\to A'(6,3)[/tex]

[tex]B(2,9)\to B'(9,-2)[/tex]

[tex]C(1,1)\to C'(1,-1)[/tex]

Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).

Answer: 0.9974

Step-by-step explanation:

Let X be the random variable that follows the normal distribution \.

If mean ([tex]\mu[/tex]) = 10 and standard deviation ([tex]\sigma[/tex]) =1

then, the probability of selecting a number between 7 and 13 = [tex]P(7<X<13)[/tex]

[tex]=P(\dfrac{7-10}{1}<\dfrac{X-\mu}{\sigma}<\dfrac{13-10}{1})[/tex]

[tex]=P(-3<z<3)[/tex]                     [Since [tex]z=\dfrac{X-\mu}{\sigma}[/tex]]

[tex]=P(z<3)-P(z<-3) \ \ \ [P(z_1<Z<z_2)=P(Z<z_2)-P(Z<z_1)]\\\\= P(z<3)-(1-P(z<3))\ \ \ [P(Z<-z)=1-P(Z<z)]\\\\=2P(z<3)-1\\\\=2(0.9987)-1\ \ [\text{By p-value table}]\\\\= 0.9974[/tex]

Hence, the probability of selecting a number between 7 and 13 is 0.9974.

After t minutes, Tank A contains

6000 gal - (2 gal/min) t

while Tank B contains

8250 gal - (3 gal/min) t

The two tanks hold the same amount of water when these quantities are equal. Solve for t :

6000 gal - (2 gal/min) t = 8250 gal - (3 gal/min) t

(1 gal/min) t = 2250 gal

t = (2250 gal) / (1 gal/min) = 2250 min

Answer:

x = -4/17

Step-by-step explanation:

Answer:

4 students is 20% of 20 students.

Step-by-step explanation:

We can say that 20 students represent 100% and that 4 students represent x% of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 %

4 students are 20 percent of 20 students.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

We can say that 20 students represent 100% and that 4 students represent x% of all students.

Thus, we can use the proportion:

20 : 4 = 100: x, or 20 / 4 = 100 / x.

cross multiply

20 x = 4 * 100

20 x = 400

x = 400: 20

x = 20 %.

therefore, we can say that 4 students are 20 percent of 20 students.

Step-by-step explanation:

|2x + 12| = 18

There are two solutions to an absolute value equation, one positive and one negative

2x+12 = 18            2x+12 = -18

Subtract 12 from each side

2x+12-12 = 18-12            2x+12-12 = -18-12

2x = 6                             2x = -30

Divide by 2

2x/2 = 6/2                     2x/2 = -30/2

x = 3                                x = -15

Answer:

x=5 over 2 (it's a fraction)

Step-by-step explanation:

STEP 1 distribute : 4-1 (2x+4)=5

4-2x-4=5

STEP 2 subtract: 4-2x-4=5

-2x=5

STEP 3 divide both sides of the equation by the same term:

-2x=5

-2x 5

----- ------

-2 -2

STEP 4 simplify:

cancel the terms that are both the numerator and denominator

divide the numbers

x= - 5 over 2 (fraction)
