**Answer 1**

**Answer:**

**9.5**

**Step-by-step explanation:**

Note the place values:

9 ones place value

.

5 tenths place value

2 hundredths place value.

You are solving for the nearest tenths. To solve, look at the place value directly next (the hundredths place value). If the value of the number is 5 or greater, round up. If it is 4 or less round down.

In this case, it is 2, so you will round down.

a. Clare is cycling at a speed of 12 miles per hour. If she starts at a position chosen

as zero, what will her position be after 45 minutes?

b. Han is cycling at a speed of -8 miles per hour; if he starts at the same zero point,

what will his position be after 45 minutes?

c. What will the distance between them be after 45 minutes?

### Answers

**Answer:**

a) 9 miles

b) 6 miles

c) 3 miles

**Step-by-step explanation:**

a) Clare's speed = 12 mph

Calculate Clare's speed in miles per minute by dividing 12 by 60 (as there are 60 minutes in an hour):

12 ÷ 60 = 0.2 miles per minutes

Therefore, position after 45 minutes: 45 x 0.2 = 9 miles

b) Han's speed = 8 mph

Calculate Han's speed in miles per minute by dividing 8 by 60 (as there are 60 minutes in an hour):

8 ÷ 60 = 2/15 miles per minutes

Therefore, position after 45 minutes: 45 x 2/15 = 6 miles

c) Distance between Clare and Han = 9 - 6 = 3 miles

to make a certain colour of household paint, you need to mix ¾ l of white paint with 15 ml of red paint and 10 ml of yellow paint. Express the paint mixture as a ratio. if you need a total volume of 31 litres of this paint, how much of each colour must you mix?

### Answers

**Answer:**

Paint mixture ratio:

0.75 : 0.015 : 0.01

Quantities of paint needed for a total volume of 31 litres:

White paint = 30 litresRed paint = 0.6 litresYellow paint = 0.4 litres

**Step-by-step explanation:**

We have been given quantities of paint in both **litres **and **millilitres**.

Therefore, first **convert millilitres **to **litres **(since the next part of the question is in litres).

Conversion:

1000 millilitre = 1 litre

To convert millilitres to litres, **divide **the quantity in millilitres **by 1000**:

[tex]\implies \sf Red\;paint:\quad 15\; ml = 15 \div 1000 = 0.015 \; litres[/tex]

[tex]\implies \sf Yellow\;paint:\quad10 \; ml = 10 \div 1000 = 0.01 \; litres[/tex]

Also convert the **quantity **of white paint to a **decimal**:

[tex]\implies \sf Whitez;paint: \quad \frac{3}{4} \;of \;a \;litre= 0.75\;litres[/tex]

Therefore, the **ratio **of **white paint** to **red paint** to **yellow paint** in litres is:

0.75 : 0.015 : 0.01

To calculate how much of each colour we must mix to make a **total **of **31 litres** of paint, first find the **constant of proportionality**:

[tex]\implies 0.75x+0.015x+0.01x=31[/tex]

[tex]\implies 0.775x=31[/tex]

[tex]\implies 0.775x \div 0.775=31\div 0.775[/tex]

[tex]\implies x=40[/tex]

Now **multiply **each **ratio **by the found **constant of proportionality**:

White paint = 0.75 x 40 = 30 litresRed paint = 0.015 x 40 = 0.6 litresYellow paint = 0.01 x 40 = 0.4 litres

### Answers

**Answer:**

7r + g = 46

7r + 2g = 50

**Step-by-step explanation:**

Hi there!

Matt and Trevon both bought supplies from a store, and we know that Matt bought 7 rose bushes and 1 geranium, and spent a total of $46 while Trevon bought 7 rose bushes and 2 geraniums, and spent a total of $50

We know that each rose bush costs a certain amount, and each geranium must cost a certain amount, but we don't know what that amount is; it's also possible that the amounts could be different

So let's say that the cost of one rose bush is r dollars; for Matt, that means that he spent 7r dollars on 7 rose bushes. Trevon also bought 7 rose bushes, meaning he also spent 7r dollars on rose bushes.

Since the cost of the geraniums can be different from the cost of every rose bush, let's express it with a different variable, like g.

Since Matt bought one geranium, he spent g dollars on that one geranium.

Trevon bought 2 geraniums, so he spent 2g dollars on the geraniums

The total cost of what Matt spent on flowers was 7r + g dollars (7 rose bushes + 1 geranium), which is equal to 46 dollars

As an equation, that can be written as 7r + g = 46

Trevon spent 7r + 2g dollars (7 rose bushes + 2 geraniums), which gave him a total of $50

As an equation, that can be written as 7r + 2g = 50

The two equations therefore are:

7r + g =46

7r+2g=50

Hope this helps!

The **value** of x and y based on the **percentages** that are given will be 11 and 7.

How to calculate the percentage

Since x is **110%** of 10. This will be;

= 110% × 10

**x = 11**

Since **y%** of 50 is 3.5. This will be:

y% × 50 = 3.5

y% = 3.5/50

0.01y = 3.5/50

**y = 7**

Solve for x then find the measure of angle A

### Answers

**Answer:**

x = 18°, ∠A = 110°

**Explanation:**

**As the lines are parallel, their sums of total interior angle is 180°**

∠A + ∠B = 180°

5x +20° +9x-92° = 180°

14x -72° = 180°

14x = 180° + 72°

14x = 252°

x = 18°

**Solve for angle A:**

∠A = 5x +20°

∠A = 5(18) +20

∠A = 110°

**Solution:**

Note that:

∠A = 5x + 20∠B = 9x - 92∠A + ∠B = 180°

Use the equation "∠A + ∠B = 180°" to solve for x and ∠A.

∠A + ∠B = 180°=> 5x + 20 + 9x - 92 = 180=> 14x - 72 = 180=> 14x = 252=> x = 252/14=> **x = 18**

Now, find ∠A.

∠A = 5x + 20=> ∠A = 5(18) + 20=> ∠A = 90 + 20=> **∠A = 110°**

1,620π in³

**Step-by-step explanation:**

The volume of a cylinder can be found with the following formula;

V = πr²h

[] Basically, the area of the circle-shape times the height.

We can plug-in our values, plug-in x, and then solve for V.

V = πr²h

V = π(4x - 6)²(11x + 12)

V = π(4(3) - 6)²(11(3) + 12)

V = π(12 - 6)²(33 + 12)

V = π(12 - 6)²(33 + 12)

V = π(6)²(45)

V ≈ 5089.38 in³

Since it is asking for in terms of pi, the answer will be 1,620π in³
