Peony mixes red paint and white paint in the ratio 1:3 She uses four tins of red paint Work out the total number of tins of paint peony uses
Answer:
16
Step-by-step explanation:
4x3=12 tins of white paint
12+4=16 total tins
The total number of tins used by the Peony will be 16.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that Peony mixes red paint and white paint in a ratio of 1:3 She uses four tins of red paint.
The Number of red tins,
R = 4 x 1 = 4
The number of white tins,
W = 4 x 3 = 12
Total number of tins,
T = R +W
T = 4 + 12
T = 16
Therefore, the total number of tins used by the Peony will be 16.

What is converse of a statement?
A conditional statement consists of two parts, a hypothesis in the “if” clause and a conclusion in the “then”
To form the converse of the conditional statement, interchange the hypothesis and the conclusion.

A shipping company has 3 different sized cubed boxes. The volume of the boxes are 216in,512in,and 1000in mia needs to ship a gift with a height of 7 in what is the height in inches of the smallest box that Mia can use
Answer:
8 inches
Step-by-step explanation:
A shipping company has 3 different sized cubed boxes.
The volume of the boxes are 216in³,512in³,and 1000in³
We find the height of each volume of box.
a) 216in³,
Volume = h³
Height = cube root (216)
= 6 in
b) 512in³
= Volume = h³
Height = cube root (512)
= 8 in
c) 1000in³
Volume = h³
Height = cube root (1000)
= 10 in
Since: Mia needs to ship a gift with a height of 7 in .
Therefore: the height in inches of the smallest box that Mia can use is 8 inches (8 in)
A water tank holds 522 gallons but is leaking at a rate of 4 gallons per week. A second
water tank holds 696 gallons but is leaking at a rate of 7 gallons per week. After how many
weeks will the amount of water in the two tanks be the same?
The amount of water in the two tanks will be the same in
weeks.
Answer:
58 weeks
Step-by-step explanation:
Water tank A = 522 - 4x
Water tank B = 696 - 7x
Where,
x = number of weeks
Equate both equations
522 - 4x = 696 - 7x
Collect like terms
522 - 696 = -7x + 4x
-174 = -3x
Divide both sides by - 3
x = -174/-3
x = 58 weeks
The amount of water in the two tanks will be the same in 58
weeks

f(x) = - 3x ^ 2 + 3x + 7 Find f(8)
Answer:
f(8) = -161
Step-by-step explanation:
Plugin 8 to each x value to get to this equation, -3(8)^2 + 3(8) + 7. Once you have done that, make sure to multiply 8 to the second power and by 3 separately to get to this equation -3(64) + 24 + 7. Combine 24 and 7 together to get 31 and multiply 64 by -3 to get -192. Add 31 now to get -161 as your answer.
Answer:
f(8)= -161
Step-by-step explanation:
fill in 8 into x, so the equation becomes
f(8)=-3(8)^2+3(8)+7
f(8)=-3(64)+24+7
f(8)=-192+31
f(8)=-161

Answer:

Step-by-step explanation:
At the end of a snow storm, Michael saw there was a lot of snow on his front lawn.
The temperature increased and the snow began to melt at a steady rate. The depth of
snow on Michael's lawn, in inches, can be modeled by the equation S = - 2t +20,
where t is the time, in hours, after the snow stopped falling. What is the x-intercept
of the equation and what is its interpretation in the context of the problem?
Answer:
The x-intercept of the function is 10 which represents the number of hours until all the snow has melted
Step-by-step explanation:
There were 0 inches of snow on the lawn after 10 hours, the x intercept of 10 represents the number of hours after the storm stopped when all the snow had melted.
-2t+20=S
-2t+20=0
-2t =-20
t=10
Water is poured into container A so that it’s 2/3 full.
Container A is then poured into container B
Calculate the depth of the water in B
if you can’t see the picture they are the measurements:
A(H =12cm W=8cm D=8cm)
B(H=8cm W=10cm D=10cm)
Step-by-step explanation:
Volume of Container A
= (8cm)(8cm)(12cm) = 768cm³.
Volume of water = 2/3 * Volume of Container A
= (2/3) * 768cm³ = 512cm³.
Base Area of Container B
= (10cm)(10cm) = 100cm².
Hence Depth of water in Container B
= 512cm³ / 100cm² = 5.12cm.
