If square A has a side of length 5 inches, how many times bigger is the area of square B if it has a side of length 25 inches?
Answer:
24 times
Step-by-step explanation:
It is given that :
The length of the side of square A = 5 inches
The length of the side of square B = 25 inches
Therefore, area of square A = 5 x 5
= 25 square inches
Similarly, area of square B = 25 x 25
= 625 square inches
Therefore, number of times the square B is bigger than the square A is given by :
[tex]$=\frac{625-25}{25}$[/tex]
[tex]$=\frac{600}{25}$[/tex]
= 24
Thus the square B is 24 times bigger than square A

Tyler has at most $20 to spend on rides and games at the carnival. Each ride costs $0.75 and each game costs $0.50. Which inequality can be used to determine how many rides r and games g Tyler can pay for at the carnival?
Answer:
The inequality that can be used to determine how many rides r and games g Tyler can pay for at the carnival is:
0.75r+0.50g≤20, where:
r is the number of rides
g is the number of games
Step-by-step explanation:
With the information provided, you can say that the amount spent at the carnival is equal to the cost per ride for the number of rides plus the cost per game for the number of games. Also, given that the statement indicates that Tyler has at most $20, the inequality would indicate that the amount spent has to be less than or equal to 20. According to this, the inequality that can be used to determine how many rides r and games g Tyler can pay for at the carnival is:
0.75r+0.50g≤20, where:
r is the number of rides
g is the number of games

2. A car is traveling on a small highway and is either going 55 miles per hour or 35 miles
per hour, depending on the speed limits, until it reaches its destination 200 miles
away. Letting x represent the amount of time in hours that the car is going 55 miles
per hour, and y being the time in hours that the car is going 35 miles per hour, an
equation describing the relationship is:
55x + 35y = 200
b. if the car spends 3 hours going 55 miles per hour on the trip, how long does it spend going 35 miles per hour
c. if the car spends no time going 35 miles per hour, how long would the trip take? explain your reasoning
Answer: b.) 1 hour at 35 mph when the car spends 3 hours at 55mph
c.) The trip will take 3.64 hours which is about about 3 hours and 38 minutes if the car travels at 55mph the entire time.
(But it could take longer if the police stop the car to issue a ticket for going 55 mph in a 35mph zone!)
Step-by-step explanation:
b.) 55(3) + 35y = 200 Multiply 55(3) = 165
165 + 35y = 200. Subtract 165 from both sides 200- 165 = 35
35y = 35 divide both sides by 35
y = 1, So the time traveling at 35mph is 1 hour
c.) 55x + 35y = 200
55x + 35(0) = 200 35×0 = 0
55x = 200 . Divide 200 miles by 55mph to find the time, x
200/55 = 3.63636 hours
To convert to minutes, multiply 60 × .63636 ≈ 38.18 minutes

To write 15/50 as a percent, you have to multiply the fraction by 100
[tex]\frac{15}{50}[/tex] x 100
dividing 100 by 50 gives 2
15 x 2 = 30%
to convert 15/50 to a decimal, first simply the fraction.
Both the numerator and denominator can be divided by 5
3/10
the next step is to divide the numerator by the denominator
3/10 = 0.3

Find the value of x in the figure below.
Step-by-step explanation:
75 is equal to opposite angle of x.
so,
75° +65°+ x=180°( by all angles sum)
140°+x=180°
x=180°-140°
x=40°
Answer:
x = 40
Step-by-step explanation:
75 + 65 = 140
180 - 140 = 40
Emmanuel bought adult and childron tiokots for his fomily to see g show. He bouant a total of 18 tickets The adult tickets cost $20 and the children tickets cost 15 If he spent a total of 1320 how many children tickets did he buy?
Answer:
8 children tickets 10 adult tickets
Step-by-step explanation:
The total amount should be $ 320 not 1,320 because if you divide that amount into 18 tickets it will be an average of $73.333 per ticket
A= adults C= children
A+C =18
C= 18-A
20A + 15(18-A) = 320
20A +270 -15A = 320
5A = 50
A= 10
10 adults 8 children
10x$20 =$ 200 8x$15 =$ 120
$200+$120 =$ 320
Answer:
The answer is 10 adult tickets and 8 children tickets.

The area of a trapezoid is 75 square in. If the one base is 12 in and the height is 5 in , what is the second base of the trapezoid?
Answer:
18
Step-by-step explanation:
The area of a trapezoid is area= ((a+b)/2)h where a = base 1, b=base2, and h=height. Since we are missing a base length, he have to work backwards. 75 (area) divided by 5 (height) = 15, so we are left with 15 = (a+b)/2. Multiply both sides by 2, we get 30 = a+b. a=12, so b = 18. Hope it helps!

Answer:
5b - 0.9b is the equivalent expression and the distributive property is used.
Step-by-step explanation:
The price of bread is marked down 18%. She purchases 5 loaves of bread. We need to rewrite the above expression.
The expression that is used to find the price of 5 loaves of bread is 5(b-0.18b).
We can use the distributive property to solve it as follows:
a(b+c) = ab + ac
Here, a = 5, b = b and c = -0.18b
5(b-0.18b) = 5(b) + 5(-0.18b)
= 5b - 0.9b
So, the equivalent expression is 5b - 0.9b. The distributive property was used to rewrite the expression.

How much greater is 40% of 30 than 20% of 10?
Answer:
10
Step-by-step explanation:
40% of 30 = 0.4 * 30 = 12
20% of 10 = 0.2 * 10 = 2
12 - 2 = 10
Answer: 10
40% of 30 is 10 units greater than 20% of 10.
What is percentage?A relative value indicating hundredth parts of any quantity.
Given that 40% of 30 and 20% of 10
40% of 30 = 40*30/100 = 12
20% of 10 = 20*10/100 = 2
(40% of 30) - (20% of 10) = 10
Hence, 40% of 30 is 10 units greater than 20% of 10.
