A cheetah can run 70 miles per hour. What is this speed in feet per hour?
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.

What is 8x99 in expression form
In expression form, 8(99) is 8 ( 100 - 1 ) = 792, by basic algebra.
What is basic algebra?Numbers, variables, constants, expressions, equations, linear equations, and quadratic equations are all part of the basics of algebra. Additionally, the algebraic expressions contain the basic arithmetic operations of addition, subtraction, multiplication, and division.
Now, Given:
8 x 99
We know 99 = 100 - 1.
Thus, by basic algebra, 8 ( 99) = 8 (100 - 1)
8 ( 100 - 1) = 8(100) - 8(1)
8( 100 - 1) = 800 - 8 = 792.

solutions pls
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]
Therefore we found the volume of the balloon when fully inflated to be 3532.5[tex]cm^{3}[/tex].

David wants to pack 574 cereal bars into bags of 10 and bags of 8. The number of bags of 8 is 2 more than the number of bags of 10. How many bags of 10 and 8 can David pack all the cereal bars into?
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).
x=31+2
x=33
Therefore, the number of bags of 8 is 33 and number of bags of 10 is 31.

The balance owed on your credit card triples from $800 to $2400 in 9 months. If the balance is growing linearly then it would take 34.9 months to reach $7000. If, on the other hand, the balance is growing exponentially, f(x)=800(1+0.13)x where x represents the number of months, what would the balance be after 34.9 months? Round your answer to the nearest cent.
The balance owed on the credit card if the growth is exponential according to the equation is; $57,528.
What is the balance owed on the credit card if the growth was exponential as opposed to linear?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

Let us consider the small triangle to be ABC and the larger triangle to be ADE

By triangle proportionality theorem,
If a line parallel to one side of a triangle intersects the other two sides, the two sides are proportionally divided.
Thus line BC is parallel to DE and hence divides AB and AD as well as
AC and AE proportionally
Thus Triangle ABC is Similar to triangle ADE by SAS
Thus,
AB/BD=BC/DE=AC/CE
Thus, using AB/BD=AC/CE

PLEASE HELP Line Segment AD=11x+10.6. Find the length of AB and CD. Show all work
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

3.1.2 List any two fixed debits and any two flexible debits for the month
3.1.3 Look at the balance column to work out the value of A, the opening balance before her salary was paid in
3.1.1
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.
3.1.2
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.
Types of fixed debts:
Automobile loansLoans on Recreation Vehicles, Boats, Motorcycles, etc.Furniture loans (if set payment, not on a credit card)Appliance loansDebt Consolidation loansStudent LoansFlexible Debit Card :
The flexible Debit card is highly favorable and the most popular transaction account. With the Flexi Debit card linked to several Postbank Savings and Investment Products, the Flexi Debit card offers you Transactional flexibility and freedom.
One can deposit your salary into the account and withdraw the money as and when needed. You can also use it for shopping instead of carrying cash.

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.

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

Given:
160 total learners34 play soccer and rugby40 play soccer and hockey42 play hockey and rugby36 play soccer only72 play hockey8 play rugby only28 play none of these sportsx play all three sportsAs "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.
