Answer: 1517.54
Step-by-step explanation:
So we can divide solving this question into two parts: the 2% compound interest and the 5% compound interest.
We know that the compound interest equations is A = P(1+r/n)^nt where:
A is final amount
P is principal (initial) amount
r is interest rate
n is number times interest compounded
t is number of time periods
Given this, in the 2% compound we know:
A = ?
P = 1200
r = 2%
n = 1 (because it didn't say how many times compounded so we assume 1)
t = 2
This becomes:
A = 1200 (1 + (0.02/1))^ 1 * 2
A = 1248.48
Because we switching to 5% from 2%, we can assume that the final amount from the 2% will be the initial amount in the 5%. Thus:
A = ?
P = 1248.48
r = 5%
n = 1
t = 4 (because there were 6 years in total and we used 2 years for 2%)
This becomes:
A = 1248.48 (1 + (0.05/1))^ 1 * 4
A = 1517.54

Find the length of AC, correct to 2 decimal places.
Hello!
This is a question relating trigonometry to unknown sides.
Here we can use the law of sines, which state that if a triangle is a right triangle, the ratio between a side and the sin of its opposite angle will be equal to any other ratio of the same type.
This means that we can set up this equation.
[tex]\frac{17}{sin(90)}=\frac{AC}{sin(38)}[/tex]
[tex]AC=17sin(38)[/tex]
Be sure to be on degrees if you're on a calculator.
[tex]AC=10.47[/tex]
Hope this helps!
If x + sin^2 theta + cos^2 theta = 4, then what is the value of x?
Answer:
x = 3
Step-by-step explanation:
[tex]x + sin^2 \theta + cos^2 \theta = 4 \\ x + 1 = 4 \\ ( \because \: sin^2 \theta + cos^2 \theta = 1) \\ x = 4 - 1 \\ x = 3[/tex]
6.
a rectangular room measuring 5.75m by 6.5 in to be covered by whole square tiles,
Calculate the size of each tile and the number of tiles required.
(3mks)
Answer:
Below.
Step-by-step explanation:
The dimensions are 5.75m * 6.5 m
= 575cm * 650 cm.
Finding the GCF:
575 = 5 * 5 * 23
650 = 5 * 5 * 26
- so t he Greatest Common Factor of these 2 is 25cm.
575 / 25 = 23
650 / 25 = 26.
So we need 23 tiles along the width of the room and the length will have 26 tiles.
Each tile with be 25cm * 25 cm. in size and the number of tiles = 23*26
= 598.

captain. If there are 20 players on the team,
how many ways he can assign the two roles?
A. 100
B. 190
C. 380
D. 450
Answer:
380
Step-by-step explanation:
A.45
B.30
C.90
D.180
E.40
F.55
G.130
H.50
Answer:
m<4=40
Step-by-step explanation:
Supplementary angles form 180 degrees
m<3 is vertical to the 50 degree angle which is equal.
so. m<3=50
m<5=90
90+50=140
180-140=40
m<4=40

Bob order 151/2 pound of cherrys fron the farm,this year they want to order 1 1/4 more pound but then 2/5 of the order they want blue berrys what is the percent
Answer:
Percentage of cherries = 60 %
Percentage of berries = 40 %
Step-by-step explanation:
He orders 15 1/2 pounds every year.
He wants more= 1 1/4 pounds
So the total pounds = 15 1/2 + 1 1/4
= 15 + 1 + 1/2 + 1/4
= 16 + (2+1)/4
= 16 + 3/4
= 16 3/4 pounds
Out of 16 3/4 pounds they want 2/5 part to be of blue berries.
So blue berries = 16 3/4 * ( 2/5)
= 67/4 * ( 2/5)
= 67/10 = 6 7/10 pounds
Amount of cherries= 16 3/4- 6 7/10
= 10 3/4- 7/10
= 10 (15- 14)/20
= 10 1/20 pounds
Percentage of cherries = Amount of cherries/ Total amount * 100
= 201/20 / 67/4 *100
= 201/20 * 4/67 *100
= 201/335 *100
= 60 %
Percentage of berries = 100- 60 = 40 %

Anika is hiking on a rectengular trail at the nation park there are four resting spots along the corners of the trail on the map they are marked with coordinates of -2,2) 1,2) 1,-2) and -2,-2 if rach unit represents 1 mile find the perimiter of the trail in miles using the coordinates
Answer:
The perimeter is 14 units
Step-by-step explanation:
Given
[tex]A = (-2,2)[/tex]
[tex]B = (1,2)[/tex]
[tex]C = (1,-2)[/tex]
[tex]D = (-2,-2)[/tex]
Required
Determine the perimeter
To do this, we simply calculate the distance between the sides of the rectangle i.e. AB, BC, CD and DA.
Distance (d) is calculated using:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
For AB
[tex]A = (-2,2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]B = (1,2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]AB = \sqrt{(-2 - 1)^2 + (2 - 2)^2} = \sqrt{9} = 3[/tex]
For BC
[tex]B = (1,2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]C = (1,-2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]BC = \sqrt{(1-1)^2 + (2--2)^2} = \sqrt{16} = 4[/tex]
For CD
[tex]C = (1,-2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]D = (-2,-2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]CD = \sqrt{(1 - -2)^2 + (-2 -- 2)^2} = \sqrt{9} = 3[/tex]
For DA
[tex]D = (-2,-2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]A = (-2,2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]DA = \sqrt{(-2--2)^2 + (-2-2)^2} = \sqrt{16} = 4[/tex]
So, the perimeter (P) is:
[tex]P = AB + BC + CD + DA[/tex]
[tex]P = 3 +4 + 3 + 4[/tex]
[tex]P = 14[/tex]
The perimeter is 14 units
Your goal is to fill a right circular cylinder shaped bucket with water. The bucket has a radius of 6 inches and a height of 12 inches. If you use a right circular cone with a 3 inch radius and a 4 inch height, how many scoops of water will it take to fill the bucket ?
Answer:
36
Step-by-step explanation:
to answer this question :
determine the volume of the cylinder and the cone. Divide the volume of the cylinder by the volume of the coneVolume of a cylinder = nr^2h
n = 22/7
r = radius = 6
h = height = 12
(22/7) x (6^2) x (12) = 1357.71 in^3
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius = 3
h = height =
4
(1/3) x (22/7) x (3^2) x (4) = 37.71
1357.71 / 37.71 = 36 times
Ameen went to the salon and had 3/8 of an inch of hair cut off. The next day she went back and asked for another 1/2 of an inch to be cut off. How much hair did she have cut off in all? Write your answer as a fraction in simplest form
Answer:
Total hair cut off = [tex]\frac{7}{8}[/tex]
Step-by-step explanation:
Given - Ameen went to the salon and had [tex]\frac{3}{8}[/tex] of an inch of hair cut off. The next day she went back and asked for another [tex]\frac{1}{2}[/tex] of an inch to be cut off.
To find - How much hair did she have cut off in all?
Proof -
Given that,
Firstly,
She cut off her hair = [tex]\frac{3}{8}[/tex]
Then,
She cut off her hair = [tex]\frac{1}{2}[/tex]
So,
Total hair cut off = [tex]\frac{3}{8}[/tex] + [tex]\frac{1}{2}[/tex]
= [tex]\frac{3 + 4}{8}[/tex] = [tex]\frac{7}{8}[/tex]
⇒Total hair cut off = [tex]\frac{7}{8}[/tex]
