The distance between the points C(-3,1) and D(5,6) is 10.3 units.
Step-by-step explanation:
Let us consider CD is a line segment.
The point C is (-3,1) and D is (5,6).
The Cartesian formula for line is used to find the length between the CD.
Distance between two points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex].
The points are (-3,1) and (5,6).
=[tex]\sqrt{(6-(-3))^2+(6-1)^2}[/tex].
=[tex]\sqrt{(6+3)^2+(6-1)^2}[/tex]
=[tex]\sqrt{9^2+5^2}[/tex].
=[tex]\sqrt{81+25}[/tex].
=[tex]\sqrt{106}[/tex].
=10.295 ≈ 10.3.
Distance between two points 10.3 units.

Tia owns a fruit shop and is selling a fresh lot of apples and oranges. She wants the ratio of apples to oranges sold to be 4 to 2. Tia
wants to sell a total of 54 apples and oranges. How many apples should she sell?
A.
52 apples
B. 36 apples
C. 9 apples
D. 32 apples
Answer:
[tex]\large \boxed{\text{B. 36 apples}}[/tex]
Step-by-step explanation:

Ava’s aquarium is 95% filled with water. The tank holds 1,120 gallons of water. Which is the remaining number of gallons of water needed to fill the aquarium to the top?
Answer:
The aquarium needs 56 more gallons to be completely filled.
Step-by-step explanation:
To get the amount remaining you have to first divide 1120 by 100
1120/100=11.2
Then multiply it by 95
11.2*95=1064
You take the maximum amount (1120) and subtract the amount in the tank (1064) to get the amount left.
1120-1064= 56
With 56 gallons as your final answer.

The student council at Princeton High School is making T-shirts to sell for a fundraiser, at a price of $11 apiece. The costs, meanwhile, are $9 per shirt, plus a setup fee of $140. Selling a certain number of shirts will allow the student council to cover their costs. How many shirts must be sold? What will the costs be?
Selling shirts will cover the $ in costs.
To cover costs, the student council needs to sell 70 T-shirts, which will cover the $770 in costs.
Explanation:To solve the student council's problem, we need to find the number of T-shirts that must be sold so that the total revenue equals or exceeds the costs associated with making the T-shirts. Let's define x as the number of T-shirts to be sold. The total revenue from selling the T-shirts at $11 apiece can be represented as 11x. The costs consist of a setup fee of $140 and $9 per shirt, so the total cost is 9x + 140. To determine when the revenue will cover the costs, we can set up the following equation:
11x = 9x + 140
Solving this equation for x, we subtract 9x from both sides:
2x = 140
Then divide both sides by 2:
x = 70
Therefore, the student council needs to sell 70 T-shirts to cover their costs, which will be $770 ($11 per shirt multiplied by 70 shirts).

What is the final amount if 943 is decreased by 13% followed by a further 6% decrease?
Give your answer rounded to 2 DP.
The final amount after a 13% decrease followed by a further 6% decrease from 943, rounded to two decimal places, is 771.19.
Explanation:To calculate the final amount after sequential percentage decreases, you first apply the initial percentage decrease to the original amount, then apply the second percentage decrease to the new, lower amount.
Here’s how you can do it step by step:
Calculate the first decrease of 13%: 943 × 0.13 = 122.59Subtract the first decrease from the original amount: 943 - 122.59 = 820.41Calculate the second decrease of 6% on the new amount: 820.41 × 0.06 = 49.2246Subtract the second decrease from the new amount: 820.41 - 49.2246 = 771.1854The calculator answer is 771.1854, but since we want the answer rounded to two decimal places, we must look at the third decimal place. Since the digit in the thousandths place (5) is greater than or equal to 5, we round up giving us a final answer of 771.19.
Sam invests $6000 in an account that pays interest of 4.5% per year.
a) How much interest would he earn each year?
b) How much would he have in his account at the end of the first year?
He would earn an interest of $270 each year and at the end of the first year he would have $6270 in his account.
Step-by-step explanation:
Step 1: Given details are Principal Amount (P) = $6000, Rate of Interest (R) = 4.5% and time (T) = 1 yearStep 2: Calculate simple interest by using the formula SI = PRT/100⇒ SI = 6000 × 4.5 × 1/100
⇒ SI = 60 × 4.5 = $270
Step 3: Calculate the amount he would receive at the end of an year by using the formula, A = P + SI⇒ A = 6000 + 270
⇒ A = $6270

Answer:
34.5 units^2
Step-by-step explanation:
The square is A = bh.
A = 7 * 3 = 24.
The triangle is A = 0.5bh.
A = 0.5 * 7 * 3 = 0.5 * 21 = 10.5.
24 + 10.5 = 34.5 units^2.

Twenty-four hundredth in decimal notation
Answer:
0.24
Step-by-step explanation:
Twenty-four hundredths = 24/100 = 24×(1/100) = 24×0.01 = 0.24
_____
Both 24/100 and 0.24 are pronounced "twenty-four hundredths."
Answer:
0.24
Step-by-step explanation:
If you say hundredths with ths it means that the number is at the right side the decimal point. so that means twenty four hundredths is at the right side of the decimal point so the answer will be 0.24 hundredths.

HELPPP....PLEASE...........
Answer:
9 1/3, 12 1/2, 14 3/4
Step-by-step explanation:
I assume the formula you’re working with is A=b*h since nothing says otherwise...
((Patio 1))
So you have your area (147) and your base (15 3/4), now you need to plug them in, which should look like this:
147= 15 3/4*h
You need to isolate your h in order to get the missing number, so you should divide both sides by 15 3/4 OR 63/4 ((15*3—>60+3=63))
Dividing by a fraction is the equivalent of multiplying by its reciprocal... so
147 * 4/63 = 588/63 which can be simplified to 84/9 once both the numerator and denominator are divided by 7
In mixed number for it is 9 3/9 which simplified becomes 9 1/3
You solve the other similarly
A cylindrical jar's lid has a radius of 4 inches. If the volume is 351.68 in , approximately what is the height of the jar?
Answer:
7 inches
Step-by-step explanation:
The volume of a cylinder is calculated using
[tex]V = \pi {r}^{2}h[/tex]
where r =4 inches is the radius and V=351.68 is the volume.
To find the height of the jar, we substitute these values and solve for h.
[tex]351.68 = 3.14 \times {4}^{2} \times h[/tex]
[tex]351.68 = 50.24h[/tex]
Divide both sides by 50.24 to get:
[tex]h = \frac{351.68}{50.24} [/tex]
h=7 inches
Therefore the height of the jar is 7 inches
Evaluate the function. F(x)=3/x-1/. F(-3)
-4/3x-3=1/3x+3/4 solve for X
Answer:
-9/4
Step-by-step explanation:
-4/3x-3=1/3x+3/4
-4/3x-1/3x-3=3/4
-5/3x=3/4+3
-5/3x=3/4+12/4
-5/3x=15/4
x=(15/4)/(-5/3)
x=(15/4)(-3/5)
x=-45/20
simplify
x=-9/4
