Step-by-step explanation:

0.8 = 8 tenths

0.03 = 3 one hundredths

80/100 is the same as 8/10 or 8 tenths

3/100 is also 3 hundredths

Answer:

function : 2 and 3

Step-by-step explanation:

a function cant have any overlapping points on the x axis, if you can draw a line up and down (vertical) and it hits two points then it isn’t a function

Part A

Refer to the diagram below. Specifically, refer to figure 1.

Point P is added to form a right triangle.

J is at (-7,2) and P is at (11,2). Segment JP is 18 units long.

We split segment JP into 4 equal pieces to get 18/4 = 4.5; this result is added onto the x coordinate of J to get -7+4.5 = -2.5 which is the x coordinate of point Q. So Q is at (-2.5, 2)

The value -2.5 is the x coordinate of point S as well.

Notice how the ratio JQ:QP is equal to 1:3.

----------

The distance from P to H is 6 units, which divided into four pieces means 6/4 = 1.5 is added onto the y coordinate of P to get 2+1.5 = 3.5; this is the y coordinate of points R and S as the diagram indicates. Like in the previous section, the ratio PR:RH is equal to 1:3

So ultimately point S is located at (-2.5, 3.5)

If we used the distance formula to compute the lengths of segments JS and SH, then we should find that they are in the ratio 1:3. In other words, segment SH is 3 times longer compared to segment JS. This would help confirm the answer. I'll let you do this confirmation part.

============================================================

Part B

Refer to figure 2 this time.

We'll have a similar thing going on here as done in part A, though the points Q and R are in different locations.

To find where Q must be, we take 5/6 of the distance from J to P (which we found was 18 units). So (5/6)*18 = 15. This 15 is added onto the x coordinate of J to get -7+15 = 8. This is the x coordinate of point Q and point T.

Similarly, (5/6)*(length of segment PH) = (5/6)*6 = 5 is added onto the y coordinate of P to form the point R(11,7). The y coordinate of this helps form the y coordinate of the point T.

In short, point T is located at (8,7)

You should find that JS/SH is equal to 5/6 when you apply the distance formula to compute the lengths of JS and SH. I'll let you do this confirmation.

Answer:

46.15%

Step-by-step explanation:

# of girls + # of boys = total # of students

12+14=26

# of girls / total # of students = percentage of girls in the class

12÷26=0.461538

Move the decimal place over two spots or multiply by 100 for the percent

46.1538%

Round up if needed, in this case I rounded up to the hundredths place.

60

Step-by-step explanation:

Answer:

67°

Step-by-step explanation:

1. The final angle in the top triangle is : 70

The angles in a triangle add up to 180° so 74 + 36 = 110 and 180 - 110 = 70

2. Vertically opposite angles are equal so the angle opposite the one we just found is 70° as well

3. The angles in a triangle add up to 180° so 70 + 43 = 113 and 180 - 110 = 67

Therefore, ? = 67°

Step-by-step explanation:

Hello!

Let's distribute the parenthesis

Solve:

Now, we can rearrange the variable so that x is on one side and the numbers are on the other.

We can isolate x by dividing by the coefficient of x (2).

The value of x is 10.

Step-by-step explanation:

Using the mean concept, it is found that the lowest possible average temperature on Wednesday, in degrees Fahrenheit, is of 72.

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In this problem, there are 3 observations, given by: 62, 58 and x.

The mean is of at least 64, hence:

[tex]\frac{62 + 58 + x}{3} \geq 64[/tex]

[tex]120 + x \geq 192[/tex]

[tex]x \geq 72[/tex]

The lowest possible average temperature on Wednesday, in degrees Fahrenheit, is of 72.

Answer:

hope this helps :)

Step-by-step explanation:

20−3x=5

Subtract 20 from both sides.

20-3x-20=5-20

⇒-3x=-15

divide both sides by 3

⇒-3x/-3=-15/-3

⇒x=5

Answer:

[tex] \sf \: d) \: x = 5[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 20 - 3x = 5

Then the value of x will be,

→ 20 - 3x = 5

→ -3x = 5 - 20

→ -3x = -15

→ 3x = 15

→ x = 15 ÷ 3

→ [ x = 5 ]

Hence, the value of x is 5.

Answer:

Step-by-step explanation:

Part A:

For Dog walking, he earns $30 for 5 hours of work.

He earns $36 for 6 hours of work.

$30/5 hours = $6/hour

$36/6 hours = $6/hour

He earns $6/hour dog walking.

For 8 hours, he earns 8 hours * $6/hour = $48

To earn $66, he works 66/6 = 11 hours.

5 30

6 36

8 48

11 66

Part B:

He earns $7/hour for yard work, so multiply the number of hours by 7 to find the money he earns.

Table for yard work

Hours     Money

5             $35

6             $42

8             $56

Part C:

For 5 hours, he earns $35 for yard work and $30 as a dog walker.

$35 - $30 = $5
