The perimeter of square is 24 meters. What is the length of one side of the square. Show your work
Answer:
6+6+6+6
Step-by-step explanation:
Perimeter of square is 24 m.
Perimeter of square = 4 × Side
[tex] \bf \implies \: \large \: 24 \: = \: 4 \: \times \: Side[/tex]
[tex]\bf \implies \: \: Side \: = \: \frac{24}{4} \\ [/tex]
[tex]\bf \implies \: \: Side \: = \: \cancel\frac{24}{4} \: ^{6} \\ [/tex]
[tex]\bf \implies \: \: Side \: = \: 6 \: meters[/tex]

Richard Brian puts $30 worth of gas in his truck. The price per gallon was $2.50. Which equation can be solved to find the number of gallons Richard Brian's purchased?
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Richard Brian puts $30 worth of gas in his truck and the price per gallon was $2.50.
The equation that can be solved to find the number of gallons Richard Brian's purchased will be the worth of gas in the truck divided by the price per gallon. This will be:
x = 30 / 2.50
where x = number of gallon.
= 12 gallons

Answer:
x = 30°
Step-by-step explanation:
Since 2 of the sides are congruent then the triangle is isosceles and the 2 base angles are congruent, both 75°
The sum of the 3 angles in a triangle = 180°, then
x = 180° - (75 + 75)° = 180° - 150° = 30°

The shelf life of a battery produced by a major company is known to be normally distributed, with a mean life of 4 years and a standard deviation of 0.75 years. What is the upper quartile of the battery shelf life? What range of years contains the middle 68% of all battery shelf lives?
Answer:
4.5 years ; (3.25, 4.75)
Step-by-step explanation:
Given that :
Mean , m = 4
Standard deviation, s = 0.75
The upper quartile, which is the 3rd quartile of a standard normal distribution is 0.67
Therefore, the upper quartile Q3:
Q3 = mean + 0.67 * standard deviation
Q3 = 4 + 0.67(0.75)
Q3 = 4 + 0.5025
Q3 = 4.5025
Q3 = 4.5 years
Range of values that contain the middle 68%
According to the empirical rule;
68% is within 1 standard deviation of the mean
Therefore ;
Interval will be ;
Mean ± 1 standard deviation
(4 - 0.75) ; (4 + 0.75)
(3.25, 4.75)
1. An AP has a common difference of 3. Given that the nth term is 32, and the sum of the first n terms is 185, calculate the value of n.
Answer:
The value of n is 10
Step-by-step explanation:
The formula of the nth term of the arithmetic progression is a[tex]_{n}[/tex] = a + (n - 1)d
a is the first termd is the common difference between each 2 consecutive termsn is the position of the termThe formula of the sum of nth terms is S[tex]_{n}[/tex] = [tex]\frac{n}{2}[/tex] [2a + (n - 1)d]
∵ An AP has a common difference of 3
∴ d = 3
∵ The nth term is 32
∴ a[tex]_{n}[/tex] = 32
→ Substitute them in the 1st rule above
∵ 32 = a + (n - 1)3
∴ 32 = a + 3(n) - 3(1)
∴ 32 = a + 3n - 3
→ Add 3 to both sides
∴ 35 = a + 3n
→ Switch the two sides
∴ a + 3n = 35
→ Subtract 3n from both sides
∴ a = 35 - 3n ⇒ (1)
∵ The sum of the first n terms is 185
∴ S[tex]_{n}[/tex] = 185
→ Substitute the value of S[tex]_{n}[/tex] and d in the 2nd rule above
∵ 185 = [tex]\frac{n}{2}[/tex] [ 2a + (n - 1)3]
∴ 185 = [tex]\frac{n}{2}[/tex] [2a + 3(n) - 3(1)]
∴ 185 = [tex]\frac{n}{2}[/tex] [2a + 3n - 3]
→ Multiply both sides by 2
∴ 370 = n(2a + 3n - 3)
∴ 370 = 2an + 3n² - 3n
→ Substitute a by equation (1)
∴ 370 = 2n(35 - 3n) + 3n² - 3n
∴ 370 = 70n - 6n²+ 3n² - 3n
→ Add the like terms in the right side
∵ 370 = -3n² + 67n
→ Add 3n² to both sides
∴ 3n² + 370 = 67n
→ Subtract 67 from both sides
∴ 3n² - 67n + 370 = 0
→ Use your calculator to find n
∴ n = 10 and n = 37/3
∵ n must be a positive integer ⇒ 37/3 neglecting
∴ n = 10
∴ The value of n is 10

If you roll a number cube two times, what is the probability of rolling an even on the first roll and a four on the second roll?
Answer:
1/12
Step-by-step explanation:
Probability is a ratio derived as the number of possible outcomes divided by the total outcome.
On a number cube, the even sides are 2, 4 and 6. This means that the possible outcome for rolling an even is 3 while the total outcome is 6. Hence the probability of rolling an even P(E)
= 3/6
The probability of rolling a 4 P(4)
= 1/6 (4 appears on one side)
Hence the probability of rolling an even on the first roll and a four on the second roll
P(En4) = 3/6 * 1/6
= 3/36
= 1/12

Find the slope of the line that contains the pair of points: (6,3)
Answer:
1/2
Step-by-step explanation:
Let the coordinate points be (6,3) and (4,2)
Slope = y2-y1/x2-x1
x1 = 6, y1 = 3, x2 = 4 and y2 =2
Substitute
slope = 2-3/4-6
Slope = -1/-2
Slope = 1/2
Hence the slope of the coordinate is 1/2
Note that the other Coordinate was assumed
A tree planter can plant 40 trees in 8 hours.
How many trees can a tree planter plant in 2
hours?
Answer:
He can plant 10 trees in 2 hours.
Step-by-step explanation:
First you need to find the number of trees he can plant in an hour.
For this purpose, we will divide 40 by 8 to get an idea about how many he can plant in an hour.
Trees planted in an hour = 40/8 = 5
Now for 2 hours = 5*2 = 10 trees.
In 5 + In x = 1
this is from my algebra 2 class and we just have to solve
Answer:
2
Step-by-step explanation:
In 5 + In x = 1
In 5 + In x = In 10 (Because In 10 = 1)
In(5x) = In 10
5x = 10
x = 10/5
x = 2
What is the function of this graph?
Answer:
x=y^2-2
Step-by-step explanation:
This graph, is a parabola that opens to the right.
To answer this question, we just use the vertex form of a sideways parabola- x=a(y-k)^2+h.
In this case, the vertex is (-2, 0), and our value of a is 1, since it opens to the right.
This gives us: x=1(y-0)^2+(-2)
Which simplifies to: x=y^2-2.
Also, the answer to the previous two questions are wrong.

There are 320 students in a school, There are 36 more boys than girls. What fraction of the students are boys?
Answer:
89/160
Step-by-step explanation:
Total number of students= 320
Total number of students=x+y=320
Let x= number of boys
Let y= number of girls
If there are 36 more boys than girls:
36+y=x
x+y=320 ( given x= 36+y)
36+y+y=320
36+2y=320
2y=320-36
2y=284
y=284/2
y=142
Therefore number of girls=142
Since 36+y=x
36+142=x
x=178
Therefore number of boys =178
Fraction of students that are boys=
178/320
89/160
