Which of the following number lines represents the solution to m/-2 - 7 = -9?
Dan invests £1500 into his bank account.
He receives 3% per year simple interest.
How much will Dan have after 2 years?
Give your answer to the nearest penny where appropriate.
Answer:
£1,725.00
Step-by-step explanation:
To calculate simple interest, we use the formula:
a = p(1 + rt)
a is the answer
p is the principle, or the starting amount of money
r is the rate, or the rate of interest (the percent)
and t is the time, or years.
First, 3% as a decimal is 0.03
So we can plug that in as r.
Then just plug the rest of the numbers in.
a = 1500(1 + 0.03 x 2)
Then just solve the equation to get 1,725.00.
Hope this helps!

8(k+3)=12k−4 k = ______
Answer:
See explanation.
Step-by-step explanation:
[tex]8(k+3)=12k-4k[/tex]
Distribute the 8
[tex]8k+24=12k-4k[/tex]
Combine like-terms on right side
[tex]8k+24=8k[/tex]
This equation is not true because for any value for k, this equation will never be true. For example, if we subtract 8k from both sides, we get
[tex]24=0[/tex]
This isn’t a true statement, so your answer would be one of the following:

Container A is a cylinder with a radius of 9 units and a height of 9 units. A right cone has been carved from its base and has a height of 9 units. Container B has the same radius as container A. Which statement derives the formula to find the volume of container A?
container A is a right cylinder that has had a right cone subtracted from its base, container B is half of a sphere
π(92)(9) − 1 over 3π(92)(9)
2[π(92)(9) − 1 over 3π(92)(9)]
1 over 3π(92)(9) − π(92)(9)
2[1 over 3π(92)(9) − π(92)(9)]
Answer:
a. π(92)(9) − 1 over 3π(92)(9)
Step-by-step explanation:
Solution given: For A
height =9units
breadth =9units
for both cylinder and cone
Volume of container A=volume of cylinder -volume of cone
=πr²h-1/3×πr²h=π(9²)9-1/3×(9²)9
so your final answer is A
a. π(92)(9) − 1 over 3π(92)(9)
The volume of the container A and container B will be π(9²)9 – (1/3)π (9²)h. Then the correct option is A.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Container A is a cylinder with a radius of 9 units and a height of 9 units. A right cone has been carved from its base and has a height of 9 units.
Then the volume of the container A will be given as
Volume of A = Volume of cylinder – volume of cone
Volume of A = πr²h – (1/3)πr²h
Volume of A = π(9²)9 – (1/3)π (9²)h
Volume of A = (2/3) π(9)³
Container B has the same radius as container A.
Volume of B = (4/6) πr³
Volume of B = (2/3) π(9)³
Then the correct option is A.

x = 97.6
Step-by-step explanation:
cos = adjacent over hypotenuse
[tex]cos(55)=\frac{56}{x}[/tex]
* multiply each side by x *
[tex]cos(55)*x=xcos(55)\\\frac{56}{x} *x=56\\56=xcos(55)[/tex]
* divide each side by cos ( 55 ) *
[tex]\frac{xcos(55)}{cos(55)} =x\\\frac{56}{cos(55)} =97.63302055[/tex]
we're left with x = 97.63302055
Our last step is to round to the nearest tenth of a foot
We get that x = 97.6

Answer:
Y = X + 15*D
Step-by-step explanation:
Y = Person Swims During Practice
X = Frien Swims During Practice
D = number of Days both Practice
its given that daily 15 minutes longer swim then Friend

Y = X + 15*D
Determine the new price after following the markdown.
original price
$72.00
markdown
15%
Choices
•$61.20
•$62.50
•$61.85
•type equation here
Answer:
$61.20
Step-by-step explanation:
15% of 72 is 10.8 (because 72 x 0.15 = 10.8)
So, the markdown is $10.80 off of $72.00
To get the new sale price, we just subtract the markdown ($10.80) from the original price ($72.00)
$72.00 - $10.80 = $61.20
So, the answer is $61.20

Your bedroom wall is 221 inches wide. You want to hang two posters, each 28 inches across, with an equal space between each poster and the wall edges. How many inches of space should you leave between the wall edge and each poster?
Answer:
55 inches
Step-by-step explanation:
2 posters x 28 inches each = 56
221 - 56 = 165 inches
3 blank spaces on wall
165 ÷ 3 = 55 inches between posters and on either side

In how many ways can a committee of two men and two women be formed from a group of nine men and nine women?
==========================================================
Explanation:
We have 9 men and we want to select 2 of them. The order doesn't matter. If order did matter, then we would have 9*8 = 72 permutations. Since order doesn't matter, we have instead 72/2 = 36 combinations. The reason why order doesn't matter is because no person outranks another on a committee. Any given seat is the same as anyone else. This is excluding any chairperson of course.
So we have 36 ways to select the men. There are also 36 ways to select the women as well for the exact same steps as listed above. This is due to there being 9 women total and we're selecting 2 of them.
Since there are 36 ways to select the two men, and 36 ways to select the two women, this leads to a total of 36*36 = 1296 different committees
It might help to think of a table that has 36 rows and 36 columns. Each row could represent a different two-person group of men while each column represents a different two-person group of women. The intersection of a given row and column would then form a unique four-person committee. So that may help visually show why there are 36*36 = 1296 different committees (each committee is an inner cell).

Write the equation of a line that is parallel to y=−5/4x+7
and that passes through the point (-4,1)
Answer:
y=-5/4x-4.
Step-by-step explanation:
parallel lines have to have the same slope so they don't intersect each other
original equation with the same slope and rewrite it using point slope form:
y-y1=-5/4(x-x1) now Substitute the point(-4,1)
y-1=-5/4(x-(-4))
y-1=-5/4(x+4)
Now we can distribute the -5/4 and add 1 to the right to get our final slope-intercept form:
y-1=-5/4x-5
y=-5/4x-4.
The parallel line of y=-5/4x+7 that passes through point (-4,1) is y=-5/4x-4.
Answer: y=-5/4x-4.

According to the above we can establish that based on the given statistics, the average household paid approximately $97.52 per year in federal gasoline taxes.
How to calculate how much average household paid per year in federal gasoline taxes?To calculate how much the average household paid per year in federal gasoline taxes, we can use the following steps:
Determine the total number of gallons of gasoline consumed by the average household per year:
Total gallons = (Total miles driven) / (Miles per gallon)Total gallons = 11,340 miles / 21.4 miles per gallonTotal gallons = 530 gallons (rounded to the nearest gallon)Calculate the total amount paid in federal gasoline taxes per year:
Total taxes = (Total gallons) * (Tax rate per gallon)Total taxes = 530 gallons * $0.184 per gallonTotal taxes = $97.52According to the above we can establish that based on the given statistics, the average household paid approximately $97.52 per year in federal gasoline taxes.
