Answer:
2x + 7y and 7g + 3h
Step-by-step explanation:
(a)
3x + 5y - x + 2y ← collect like terms
= (3x - x) + (5y + 2y)
= 2x + 7y
(b)
3g + 5h + 4g - 2h ← collect like terms
= (3g + 4g) + (5h - 2h)
= 7g + 3h
Answer:
A) 2x + 7y
B) 7g + 3h
Step-by-step explanation:
A) 3x + 5y - x +2y =
3x - x = 2x
5y + 2y = 7y ans: 2x + 7y
B) 3g + 5h +4g - 2h =
3g + 4g = 7g
5h - 2h = 3h ans: 7g + 3h

The surface area of a cuboid is 102 cm2. If its length is 2 cm and its breadth is 3 cm, find its height.
Answer:
Height h = 9 cm
Step-by-step explanation:
Given:
Surface area of cuboid = 102 cm²
Length l = 2 cm
Breadth b = 3 cm
Find:
Height h
Computation:
Surface area of cuboid = 2[lb + bh + hl]
102 = 2[(2)(3) + (3)(h) + (h)(2)]
51 = 6 + 3h + 2h
45 = 5h
Height h = 9 cm
Answer: 9 cm
Step-by-step explanation:
4. At a certain time of day, an 18-foot pole casts a shadow that forms an angle of 50° with the
ground. How long is the shadow?
Step-by-step explanation:
Opposite to the angle = Pole
Adjacent to the angle = Shadow
Therefore tan50° = 18ft/x,
x = 18ft / tan50° = 15.1ft.

On Saturday, 4.14 inches of snow fell, and on Sunday, 0.93 inch of snow fell. On Monday, twice as much snow fell as fell on Sunday. How much snow fell during the 3-day period?
Answer:
The answer is 6.93 inches of snow.
Step-by-step explanation:
Snow fall on Sunday: 0.93. Twice as much on Monday: 0.93x2=1.86
Add it all up: 0.93+4.14+1.86=6.93
Sally plans to retire at the age of 64 and has an account that will provide 6% interest compounded monthly. Determine how much money needs to be in Sally's account on the day sure turns 64 if she would like to be able to receive monthly payments of $9500 from age 64 until age 83.
Answer:
She needs to have $694,700 in her account
Step-by-step explanation:
Here, we want to know the amount that should be in Sally’s account on that day she turns 64
Firstly, we need to know the difference between the ages of 64 and 83
The difference between these ages are 83-64 = 19
So, she intends receiving $9,500 per month for 19 years
The number of months in 19 years is 19 * 12 = 228 months
So, the total amount of money she needs is 228 * 9,500 = $2,166,000
Now, we have an interest that would be compounded but in this case, we already have the amount needed but what we need is the principal to be compounded in this case
The formula for compound interest here is;
A = P( 1 + r/n)^nt
where A is the amount which is 2,166,000
P is ?
r is the interest rate = 6% = 6/100 = 0.06
n is the number of times we are compounding in a year; since it is monthly, that would be 12 times in a year
t is the number of years which is 19 in this case
Substituting all values, we have that;
2,166,000 = P( 1 + 0.06/12)^(12*19)
2,166,000 = P(1.005)^(228)
P = 2,166,000/(1.005)^228
P = $694,699
This rounded to a whole dollar is P = $694,700

Greg and Kevin both travel between two towns that are 90 miles apart. Greg travels and it takes him 1 hour 30 minutes. Kevin cycles and it takes him 7 hours 30 minutes. Work out the difference between the average speed.
Answer:
48 miles/hour
Step-by-step explanation:
The average speed is the ratio of the total distance traveled to the total time taven, it i given by the formula:
Average speed = total distance / total time
For Greg, the total distance = 90 miles and the total time = 1 hour 30 minutes = 1 hour + (30/60) hour = 1.5 hours. Hence:
Average speed = 90 / 1.5 = 60 miles/hour
For Kevin, the total distance = 90 miles and the total time = 7 hour 30 minutes = 7 hour + (30/60) hour = 7.5 hours. Hence:
Average speed = 90 / 7.5 = 12 miles/hour
Difference between the average speed = 60 miles/hour - 12 miles per hour = 48 miles/hour

10. A bag contains 4 red balls, 6 green balls and some white balls. If the probability of not drawing a white ball in one draw be \(\frac{2}{3}\) then find the number of white balls.
Answer:
No of white balls = 5
Step-by-step explanation:
Given that,
Total no of red balls = 4
Total no of green balls = 6
The probability of not drawing a white ball in one draw be, [tex]P=\dfrac{2}{3}[/tex]
We need to find the number of white balls. Let there are x balls.
The probability of drawing a white ball = 1 - the probability of not drawing a white ball
= 1 -2/3
= 1/3
Using the formula for solving probability of having a white ball.
[tex]P=\dfrac{\text{favorable outcome}}{\text{total no of outcomes}}\\\\\dfrac{1}{3}=\dfrac{x}{4+6+x}\\\\\dfrac{1}{3}=\dfrac{x}{10+x}\\\\10+x=3x\\\\10=2x\\\\x=5[/tex]
Hence, there are 5 white balls.
An oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours. Which graph has a slope that best represents this rate?
Answer:
Graph G
Step-by-step explanation:
The graphs are attached
Given that the oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours, hence the rate at which the shaft drills = 7 meter / 2 hours = 3.5 meters per hour
Since the drill goes into the ground, hence the rate is negative that is -3.5 meters per secong
The slope (rate of change) of a line (m) is given by:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
a) For graph F, the line passes through the point (0,0) and (10, -20). Hence:
[tex]Slope\ of\ line\ F=\frac{-20-0}{10-0} =-2\ meters\ per\ second[/tex]
b) For graph G, the line passes through the point (0,0) and (10, -70). Hence:
[tex]Slope\ of\ line\ G=\frac{-70-0}{10-0} =-7\ meters\ per\ second[/tex]
c) For graph H, the line passes through the point (0,0) and (10, -35). Hence:
[tex]Slope\ of\ line\ H=\frac{-35-0}{10-0} =-3.5\ meters\ per\ second[/tex]
d) For graph J, the line passes through the point (0,-3.5) and (10, -3.5). Hence:
[tex]Slope\ of\ line\ j=\frac{-3.5-(-3.5)}{10-0} =0\ meters\ per\ second[/tex]
Answer:The answer is H , It is the graph where -10 is right below the 0 on the y.

A cheetah can run a rare of 105,600 years per hour find the number of miles the cheetah could run at this rate in 5 minutes.
Answer:
360 yards per 5 minutes.
Step-by-step explanation:
A cheetah can ride up to 105,600 yards per hour.
An hour is equal to 60 km.
It can run up to 'x' miles per 5minutes.
So, 360 x 5/ 5
= 1800/5
= 360 yards per 5 minutes.
