Answer:
0.5 kg/week
Step-by-step explanation:
rate of change = (change in weight)/(change in time)
rate of change = (8.4 kg - 2.4 kg)/(18 weeks - 6 weeks)
rate of change = 6 kg / 12 weeks
rate of change = 0.5 kg/week

This is 8th grade math 5y+2×5h=4h Solve for h
Answer:
h= −5/6y (negative 5 y over 6)
Step-by-step explanation:
5y+(2)(5)h=4h
Step 1: Add -4h to both sides.
10h+5y+−4h=4h+−4h
6h+5y=0
Step 2: Add -5y to both sides.
6h+5y+−5y=0+−5y
6h=−5y
Step 3: Divide both sides by 6.
6h/6=−5y/6
h=−5/6y
Answer:
h = - 5y/ 6
Step-by-step explanation:
5y + 2 * 5h = 4h
Using BODMAS
Perform multiplication first
5y + 10h = 4h
Collect like terms
5y = 4h - 10h
5y = - 6h
Divide both sides by - 6
5y / - 6 = - 6h / - 6
h = - 5y/ 6

45 girls tried out for the field hockey team. 20% of the girls who tried out did not make the team. How many girls did not make the team?
Answer:
9 girls
Step-by-step explanation:
total girls tried out = 45
did not make the team
= 20% of the girls
= 20/100 × 45
= 9 girls
A rhombus, which is a quadrilateral with 4 equal sides, is plotted on the coordinate plane. The coordinates of the vertices are: (−1,0), (4,0), (2,4), and (7,4). How long is each side of the rhombus?
Answer:
Each side of the Rhombus is 5 units
Step-by-step explanation:
Since the sides of a rhombus area all equal in length;
Then, the length of a side is enough to get the lengths of the other sides
Mathematically, finding the distance between two points out of what we are given will be enough to get the measure of one of the side of the rhombus
We apply the distance formula appropriately to get the distance between the side of the Rhombus
D = √(x2-x1)^2 + (y2-y1)^2
let us use the points (-1,0) and (4,0)
D = √(4 + 1)^2 + (0-0)^2
D = √25
D = 5
What is the value of x in the equation 6(x +11)= -300?
Answer:
-61
Step-by-step explanation:
We use the distributive property to distribute 6 to both x and 11. This gives 6x+66=-300. Subtracting both sides by 66 gives 6x=-366. Dividing both sides gives x=-61.

Step-by-step explanation:
.If 65+5y = 82, 3x +23= 54 and 5z +43= 110, find 3x+ 5y +5z
Step-by-step explanation:
65+5y=82
5y=82-65
5y=17
y=17/5=3.4
3x+23=54
3x=54-23
3x=31
x=31/3=10.3
5z+43=110
5z=110-43
5z=67
z=67/5=13.4

A cube has a surface area of 600 square meters. What is its volume?
A.600 m³
B.300 m³
C.100 m³
D.1000 m³
Answer: D, 1000 m^3.
Step-by-step explanation: We can find the volume by breaking down the surface area.
The formula for the surface area of a cube is 6*x^2 with x being the side length and 6 being the number of sides. Thus we can form the equation as follows:
600 = 6*x^2 - original equation
x^2 = 100 - divide both sides by 6
x = 10 - square root both sides
Thus, the side length is 10.
We can find the volume with the formula l*w*h or, in this case, x^3.
We know that x = 10, so x^3 must be 1000.
Thus, the answer is D, 1000 m^3.

Salma used a photocopier to dilate the design for a monorail track system. The figure shows the design and its photocopy: Two irregular quadrilaterals ABCD and EFGH are drawn. EFGH is the photocopy of design ABCD. AB measures 15 meters, DC measures 17 meters. No dimensions are shown on EFGH. The ratio of AD:EH is 1:2. What is the length, in meters, of side GH on the photocopied image? 15 17 30 34
Answer:
The answer is 34
Step-by-step explanation:
The ratio of AD:EH is 1:2, so therefore the other line segments have the same ratio. Using this logic, we see that DC is equal to 17 m, and we need to find GH. All we do now is double the measurement of DC since the ratio of the two shapes is 1:2.
Therefore, 17 * 2 = 34
Answer:
34

The local candle store marks up the price of its candles by 75% before selling them. If the store paid
the distributor $6.99 per candle, how much will a candle cost in the store?
Answer:
$12.23
Step-by-step explanation:
75/100 = 0.75
0.75 x 6.99 = 5.2425
6.99 + 5.2425 = 12.2325

Jonathan is shopping for a frame for a square painting. Each side measures 9.5 inches. What is the perimeter of the painting?
Is it a, b, c, d, plz answer this
Answer:
d 4x^2 + 24x - 8
Step-by-step explanation:
Perimeter of the rectangle = 2x² - 5 + 12x + 1 + 2x² - 5 + 12x + 1
= (2x²+ 2x²) + (12x+ 12x) + (- 5 + 1 - 5 + 1)
= 4x² + 24x - 8
Simplify: (5x2 - 9x + 3) + (4x2 + 4x - 12)
(1) 9x2 + 5x - 9
2) 9x2 - 5x + 15
3) 9x² - 5x-9
4) 9x2 - 13x - 9
Answer:
3) 9x² - 5x - 9
Step-by-step explanation:
Combine like terms
5x² - 9x + 3 + 4x² + 4x - 12 = 5x² + 4x² - 9x + 4x + 3 - 12
= 9x² - 5x - 9

The probability that event A occurs is 0.4, and the probability that events A and B both occur is 0.25. If the probability that either event A or event B occurs is 0.6, what is the probability that event B will occur
Answer:
The probability that event B will occur is 0.45
Step-by-step explanation:
Given;
probability that event A occurs, P(A) = 0.4
the probability that events A and B both occur, P(A ∩ B) = 0.25
the probability that either event A or event B occurs, P(A ∪ B) = 0.6
To determine the probability that event B will occur, we use probability addition rule;
P(A) + P(B) = P(A ∩ B) + P(A ∪ B)
0.4 + P(B) = 0.25 + 0.6
0.4 + P(B) = 0.85
P(B) = 0.85 - 0.4
P(B) = 0.45
Therefore, the probability that event B will occur is 0.45
