a. 9 units
b. 6.9 units
c. 9.2 units
d. 5 units

need an explanation if possible please.

Answer:

AB=11.4

CD=24.4

Step-by-step explanation:

Since AD=11x+10.6, then AB+BC+CD = AD.

Hence,

2x+3+21+7x-5=11x+10.6

Combine like terms:

9x+19 = 11x+10.6

Subtract 9x on both sides:

19 = 2x+10.6

Subtract 10.6 on both sides:

2x=8.4

Divide by 2 on both sides:

x=4.2

Since AB=2x+3, AB=11.4

Since CD=7x-5, CD=24.4

The balance owed on the credit card if the growth is exponential according to the equation is; $57,528.

It follows from the task content that the initial amount owed was; $800.

On this simple note, since the equation given in the task content for the exponential growth from above is;

f(x)=800(1+0.13)^x

So therefore, when x = 34.9 months; we then have;

f(x)=800(1+0.13)^34.9

f(x) = 800(1.13)^34.9

f(x) = 800 × 71.19

f(x) = $57,528

Answer:

The answer is the bottom right diagram.

Step-by-step explanation:

the speed of the Cheetah in feet per hour will be 369600 feet per hour when the speed if 70 miles per hour.

Speed of the Cheetah = 70 miles / hour

1 mile = 5280 feet

Now, we will convert 70 miles into feet.

For this, we will use the operation of multiplication.

We will multiply 5280 to 70 to convert the miles into feet.

So, the speed of the Cheetah will become:

Speed of the Cheetah = 5280 × 70 / hour.

Speed of the Cheetah = 369600 feet / hour.

Therefore, we get that, the speed of the Cheetah in feet per hour will be 369600 feet per hour when the speed if 70 miles per hour.

Step-by-step explanation:

(1.28 x 10^5) + (1.13 x 10^3)

--------------------------------------------

1.28 = 128/100 = 128/10^2

1.13 = 113/100 = 113/10^2

Answer:

x = 18

Step-by-step explanation:

Given:

As "x" learners play all three sports, the Venn diagram should have three overlapping circles labelled soccer (S), rugby (R) and hockey (H).

x play all three sports:  Label the area that's in S, R and H with x.

8 play rugby only:  Label the area that is R only with 8.

36 play soccer only:  Label the area that is S only with 36.

28 play none of these sports:  Place 28 outside the three circles.

34 play soccer and rugby:  Place "34 - x" in the area that's in S and R.

40 play soccer and hockey:  Place "40 - x" in the area that's in S and H.

42 play hockey and rugby:  Place "42 - x" in the area that's in H and R.

72 play hockey

72 is the total for all the sections of H.

⇒ H = 72 - x - (40 - x) - (42 - x)

⇒ H = 72 - x - 40 + x - 42 + x

⇒ H = x - 10

Place "x - 10" in the area that is H only.

The total number of learners is 160.

Therefore, to find x, sum the areas of the Venn diagram and equal to 160:

⇒ 36 + 8 + 28 + 34 - x + x + 40 - x + 42 - x + x - 10 = 160

⇒ 36 + 8 + 28 + 34 + 40 + 42 - 10 - x + x - x - x + x = 160

⇒ 178 - x = 160

⇒ x = 178 - 160

⇒ x = 18

Finally, substitute x = 18 into the Venn diagram.

Answer:

x = 23

y = 139

Step-by-step explanation:

3x + 2x-5 + 70 = 180

5x = 115

x = 115/5

x = 23

y = 180 - (2x-5)

y = 180 - 41

y = 139

We need to know the formula for volume of a sphere to solve this question.The volume of Darragh's balloon when it is fully inflated is 3532.5[tex]cm^{3}[/tex]

A sphere can be called a circle in 3D, for example a ball is a sphere. There can be solid spheres and hollow spheres, a balloon is a hollow sphere because it has air inside it. The volume of a sphere can be calculated irrespective of it being a solid or a hollow sphere. The volume of a sphere is the capacity the sphere has, incase of a balloon the volume of a balloon means it's capacity to hold air in it. The formula for volume of a sphere is

V=[tex]\frac{1}{3}[/tex]π[tex]r^{3}[/tex] where V is the volume, r is the radius of the sphere

In the question it is given that radius of the sphere when fully inflated is 15cm

V=[tex]\frac{1}{3}[/tex]×3.14×15×15×15=3532.5 [tex]cm^{3}[/tex]

574 cereal bars will be placed in bags of 10 and bags of 8 by David. The number of bags of 8 is 33 and number of bags of 10 is 31.

Given that,

574 cereal bars will be placed in bags of 10 and bags of 8 by David. Two more bags of eight than bags of ten make up the total.

We have to find how many 10 and 8-bag sets of cereal bars can David fit.

Let us take,

x be number of bags of 8 and y be number of bags of 10.

So, we can write as

8x+10y=574→equation(1)

x=y+2→equation(2)

Taking the x value form equation(2) and putting in equation (1).

We get,

8(y+2)+10y=574

8y+16+10y=574

18y+16=574

18y=574-16

18y=558

y=558/18

y=31

We got y=31 substitute y value in equation(2).

In the year 2014, the total average credit card debt for a U.S. household was 13,773 dollars.

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In order to predict the total average credit card debt in 2014, we would determine the number of years (t) from 1995 to 2014 and then substitute the value into the given expression as follows:

Number of years, t = 2014 - 1995

Number of years, t = 19 years.

Substituting the years into the expression, we have;

Total average credit card debt = 417t + 5850

Total average credit card debt = 417(19) + 5850

Total average credit card debt = 7,923 + 5850

Total average credit card debt = $13,773.

Step-by-step explanation:

the total distance covered by the bus is 41.67 km in 50 minutes.

For first 25 minutes:

Speed of the bus = 40 km / hr.

Time = 25 minutes

Distance = Speed × Time

Distance = 40 km / hr. × 25 / 60 hr.

Distance = 16.67 km

For the next 25 minutes:

Speed of the bus = 60 km / hr.

Time = 25 minutes

Distance = Speed × Time

Distance = 60 km / hr. × 25 / 60 hr.

Distance = 25 km

Total distance covered = 16.67 km + 25 km

Total distance covered = 41.67 km.

Answer:

Debits and credits are used to monitor incoming and outgoing money in your business account. In a simple system, a debit is money going out of the account, whereas a credit is money coming in. However, most businesses use a double-entry system for accounting. This can confuse inexperienced business owners, who see the same funds used as a credit in one area but a debit in the other.

Double-Entry Accounting

When you look at your business finances, there are two sides to every transaction. This means that the rent is one account with a balance due and the business checking is another account that pays the balance due. So the same money is flowing but is accounting for two items. The double-entry system creates a chart of accounts. These include items such as rent, vendors, utilities, payroll, and loans.

Fixed Debit or Fixed debt:

A fixed debt or installment loan is generally one in which a borrower makes regular payments, where the debt has a beginning date, an end date, a fixed interest rate, and a fixed monthly fee (most installment loans are paid monthly). In other words, they adhere to a set amortization schedule. The interest on these type of loans are generally not tax deductible like mortgage loans and therefore are considered consumer debt. While many fixed-rate mortgages are fixed debts we have separated them since fixed debts outside of mortgages are considered consumer debt.

Let f(x) = (x+3)^(1/3).

First, we have

lim_(x → -3) f(x) = (-3+3)^(1/3) = 0 = f(-3)

So f(x) is continuous at a = -3.

Next we have

lim_(h → 0) [f(-3+h) - f(-3)] / h

= lim_(h → 0) h^(1/3) / h

= lim_(h → 0) 1 / h^(2/3)
