what is 2/3d -8=1/2d

Answer:

Yes

Step-by-step explanation:

10x + 2y > 3

Substitute the point into the inequality

10(4)+2(3) > 3

40+6>3

46>3

This is a true statement so the point is a solution

Answer:

Step-by-step explanation:

its 90 degrees so the other side will be the same

Answer:

b=20

Step-by-step explanation:

a^2 + b^2 = c^2

15^2 + b^2 = 25^2

225 + b^2 = 625

b^2 = 625-225

b^2 = 400

b = 20

Answer:

a) 5.2 cm

b) 296.38 cm²

Step-by-step explanation:

a) Encontrar la apotema

La fórmula se da como:

A = s / 2 bronceado (180 / n)

s = Largo del lado = 6cm

n = Número de lados = 6 porque el polígono es un hexágono

Por eso,

Apotema = 6/2 × bronceado (180/6)

= 6/2 × tan 30

= 5.1961524227cm

Aproximadamente = 5.2 cm

Apotema = altura de las caras triangulares = 5.2cm

b) Superficie total

Área de superficie de una pirámide hexagonal = 3√3 / 2b² + 3b√h² + 3b² / 4

b es la longitud de la base. = 6cm

s es la altura inclinada. = 10cm

3√3 / 2 × 6² + 3 × 6√10² + 3 × 6² / 4

A = 296.38 cm²

(If you need the actual explanations for each one, just ask in comments)

Step-by-step explanation:

1: D

2: G

3: A (60/100 = 6/10 = 3/5)

4: H (Min = 18, Q1 = 19, Median = 23, Q3 = 24, Max = 26)

5: C (2:6 = 1:3; 3:9 = 1:3)

6: J (2:15 = 10:75; multiply each side by 5)

7: A (A & B: 6*2/3 = 4, 4 < 6, 4 not > 6. C: 6*3/2 = 9, 9 not < 6. D: 6*3/3 = 6 not > 6).

Answer:

The first operation is to add, and you are adding 3 to both sides of the equation to isolate the x.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. You are solving for the variable, x, when solving this equation.

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

The first step is to add 3 to both sides of the equation:

(x/3) - 3 (+3) = 11 (+3)

(x/3) = 11 + 3

(x/3) = 14

The second step is to multiply 3 to both sides of the equation:

(x/3) * 3 = (14) * 3

x = 14 * 3

x = 42

42 would be your final answer.

Complete question :

The tower is 10.00 m tall, and the angle of depression from the top of the tower to the point on the ground is 22°How far is the point from the base of the tower.

Answer:

4.04 meters

Step-by-step explanation:

To obtain the distance between baso of tower and point P on the ground as shown in the solution diagram :

Using trigonometry :

Tan θ = Opposite / Adjacent

Tan 22° = x / 10

0.4040262 = x / 10

0.4040262 * 10 = x

x = 4.04

Hence, distance between base of tower and point P on the ground is 4.04 meters

Answer:

13 hours

Step-by-step explanation:

First you have to find the hourly rate at which money is being earned. To do so you divided the money earn ($342) by how many hours it took to earn (18 hours).

Once you do that you're given $19.00 per hour.

Now take the money earned with the unknown time ($247) and divide it by money being made per hour ($19)  and you're given 13 hours

Answer:

13

Step-by-step explanation:

First, you need to find out how much money he is making per hour. To do that, we need to do $342 divided by 18 hours. This gives us 19. We now know that Kevin is making $19 an hour. Next, do $247 divided by $19. This gives us 13. He would need to work 13 hours to make $247.

Answer:

80

Step-by-step explanation:

14 × 20 = 280

1400 - 280 = 1120

1120 ÷ 14 = 80

Answer:

We know that:

She makes $19 per hour of lifeguarding.

She makes $8 per hour walking dogs.

She can work at most 7 hours per week.

She must earn a minimum of $80 per week.

If x represents the number of hours lifeguarding and y represents the number of hours walking dogs, the inequalities will be:

x + y ≥ 7 hours.

(this says that she can work at most 7 hours per week)

x*$19 + y*$8 ≥ $80

(this says that she can earn a minimum of $80)

Then the system of inequalities is:

x + y ≥ 7 hours.

x*$19 + y*$8 ≥ $80

To graph these two we can write them as lines in standard form and simply graph both inequalities, the solution of the system will be the intersection between the solutions of each inequality.

Here we also should add the inequalities:

x ≥ 0

y ≥ 0

So we only look at the first quadrant.

The graph can be seen in the image below: (the dark blue is the solution region for the first inequality, the light blue one is the solution region for the second inequality)

One possible solution can be:

x = 4 and y = 1

or

x = 4 and y = 2

and there are a lot of other possible solutions.

Answer:

No of hits = 26

Step-by-step explanation:

Given that,

Batting average = 0.4727272

His player has 55 at bats.

We need to find the number of hits. Let the number of hits be x. Using formula for average as :

[tex]\dfrac{x}{55}=0.4727272\\\\x=0.4727272\times 55\\\\x=25.99\\\\or\\\\x=26[/tex]

So, there are 26 number of hits.

Answer:

Each part is 56 11/15 m long.

Step-by-step explanation:

325 4/5 - 150 3/5

= 170 1/5

170 1/5 = 851/5

851/5 / 3

= 851/5 * 1/3

= 851/15

= 56 11/15.
