Answer:
K = -50
Step-by-step explanation:
0.8(-50) - 20 = -60, because 0.8(-50) = -40, and when you subtract a negative you would "add" those numbers. So it would be 40 + 20 = 60, which would make it -60.
Answer:
k equals -50Step-by-step explanation:
0.8 k - 20 = -60
0.8k = -60 + 20
0.8k = -0
k = [tex]\frac{-40}{0.8}[/tex]
k = -50
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.
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 %

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]
Michael breeds chickens and ducks.
Last month, he sold 50 chickens and 30 ducks for $550. This month, he sold 44 chickens and 36 ducks for $532.
How much does a chicken cost, and how much does a duck cost?
A chicken costs $_____ and a duck costs $_____.
Answer:
Chicken:$8 Ducks:$5
Step-by-step explanation:
Let's assume
Chickens= c
Ducks=d
50c + 30d = 550 (divide this by 10)--- 5c+3d=55
44c + 36d = 532 (divide this by 4)--- 11c+9d=133
Solving simultaneously:
5c + 3d = 55 (x9)
11c + 9d = 133 (x3)
45c + 27d = 495
33c + 27d = 399
By subtraction we get:
(45c-33c+27d-27d)= 96
12c = 96
Chicken = $ 8 (96/12)
Ducks: 50(8)+ 30d = 550
30d = 150
Ducks = $5 (150/30)

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!

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
hey i just need an answer and possibly a step by step thanks !!!
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

Step-by-step explanation:
Yes, We can find the cost of one admission to the water park,
We can form two linear equation with two variables and by solving the equation we can determine the cost of one admission.
Cost of 15 people's admission and 8 rental tube is $ 263.25
15x + 8y = 263.25 -------------(I)
Cost of 20 people's admission and 13 rental tubes is $ 358
20x + 13y = 358 ------------(II)
(I) * 13 195x + 104y = 3422.25
(II)*(-8) -160x - 104y = - 2864 {Now add and so y will be eliminated}
35x = 558.25
x = 558.25/35
x = 15.95
Cost of one admission = $ 15.95
2x - 42 = 94
Solve for x
Answer:
x = 68
Step-by-step explanation:
2x - 42 = 94
Use inverse operations to add 42 to both sides of the equation.
2x - 42 + 42 = 94 + 42
Simplify this to-
2x = 136
Now divide 2x and 136 by two for-
2x/2 = 136/2
Simplify.
x = 68
The answer, then, is x = 68.
I hope this helps ^^
