20% of 30 ___30% of 40

Answers

Answer 1

Answer:

20% of 30 < 30% of 40

Step-by-step explanation:

Find 20% of 30

20/100 = x/30

Cross multiply

20 × 30 = 100 × x

600 = 100x

Divide both sides by 100

6 = x

Find 30% of 40

30/100 = x/40

Cross multiply

30 × 40 = 100 × x

1200 = 100x

Divide both sides by 100

12 = x

Compare the two answers:

6 and 12

6 < 12

Question

( 10 + 5x )7

                                                                                                                                 

Lets solve this easily.

So, basically, 10 + 5x is 15 but we still didn't

get rid of the x so therefore it's still 15x and then there's 7 so we multiply 15 x 7 giving us 105x.

Hence, the answer is.

(C), 70 + 35x is the answer.

Answers

Answer:

Step-by-step explanation:

A line can be defined by any two points on the line andhas the form

y=mx+b

Where m=slope and b=y intercept (value of y when x=0)

Slope is defined as

m=(y2-y1)/(x2-x1), we have points (0,7) and (1,4)

m=(4-7)/(1-0)

m=-3/1

m=-3 so the line is thus far

y=-3x+b, since we have the point (0,7) we know that b=7 so the line is

y=-3x+7

A y = 2x + 3
© y=-3x + 3
B y = - 2x + 2 / 2
D y = - 2x + 3

Answers

Answer:

D

Step-by-step explanation:

The line intercept y axis in (0,3), so in the generic equation y= mx + b, b must be 3. The line is also decreasing, so m must be negative

We have two options: B and D

If we try to put y=0 in these equations we have:

-1/2x + 3 = 0

Let’s solve the equation

-x + 6 = 0

x -6 = 0

x = 6

Checking the graph we notice that the line doesn’t intercept x axis in (6,0), so option B is wrong

For be sure, let’s try the same with option D

-2x + 3 = 0

-2x = -3

x = 3/2

This time is correct, so D is the right answer

Is D. the right answer

trigonometry, find the missing side(s)​

Answers

Answer:

x = 8.92 units

Step-by-step explanation:

From the triangle given in the picture,

Missing side of the triangle is the opposite side of the angle measuring 28°

And hypotenuse measuring 19 units has been given.

So, we will use sine ratio for the given angle.

sin(28°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(28°) = [tex]\frac{x}{19}[/tex]

x = 19sin(28°)

x = 8.92 units

At an amusement park, the cost of an adult's ticket is $22.50, and the cost of a child's ticket is $12.50. A group of 10 people purchased tickets for the amusement park, and paid a total of $155.00, excluding tax. How many children were in the group? How many adults were in the group?

Answers

Answer:

is there any more information you could give?

Step-by-step explanation:

**i promise to provide a real answer**

Answer:

7 children and 3 adults

Step-by-step explanation:

We should set up a system of equations for this problem, so let's say that:

x represents the number of children

y represents the number of adults

We know there is a total of 10 people, so:

x + y = 10

We also know that each adult had to pay $22.50 and each child had to pay $12.50. Their total amount paid is $155.00, so:

12.50x + 22.50y = 155.00

Simplifying this a bit:

12.5x + 22.5y = 155

Now, we can use the substitution method to solve this system of equations:

x + y = 10

y = 10 - x

12.5x + 22.5y = 155

12.5x + 22.5 (10 - x) = 155

12.5x + 225 - 22.5x = 155

12.5x - 22.5x = 155 - 225

-10x = 155 - 225

-10x = -70

x = [tex]\frac{70}{10}[/tex]

x = 7 children

Now we substitute back into the system of equations:

x + y = 10

7 + y = 10

y = 10 - 7

y = 3 adults

EFGH is a parallelogram. Find the measure of FG and EG
​

Answers

Answer:

FG = 44

EG = 80

Step-by-step explanation:

For FG:

1) 5z - 16 = 3z + 8

2) 5z = 3z + 24

3) 2z = 24

4) z = 12

5) 3(12) + 8 = 44

For EG:

1) 2w + 22 = 4w + 4

2) 2w = 4w - 18

3) -2w = -18

4) w = 9

5) 4(9) + 4 + 2w + 22 = 80
