Brent runs around a football field ,14m long and 12m inside. How much metre does Brent need in two laps
Answer:
Distance cover by Brent in 2 Lap = 104 meter
Step-by-step explanation:
Given:
Length of football field = 14 m
Width of football field = 12 m
Find:
Distance cover by Brent in 2 Lap
Computation:
Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field
Perimeter of rectangle = 2[l+b]
Perimeter of rectangular field = 2[14 + 12]
Perimeter of rectangular field = 2[26]
Perimeter of rectangular field = 52 m
Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field
Distance cover by Brent in 2 Lap = 2 x 52
Distance cover by Brent in 2 Lap = 104 meter
Triangle ABC has vertices A(1,4), B(-1,5), and C(1,-4). Triangle ABC is dilated and
B' is located at (-3,15). What is the y-coordinate of C'?
Answer:
-12
Step-by-step explanation:
The coordinates of B' are just 3 times the coordinates of B, so the multiplier in the dilation is 3.
C' is the point with coordinates 3 times the coordinates of C, making C'(3, -12).
The y-coordinate is -12.
What is the area of this square with sides of 5x⁴y²?
Answer:
Area of given Square = 25x⁸y⁴
Step-by-step explanation:
Given:
Side of a square = 5x⁴y²
Find:
Area of given Square
Computation:
Area of Square = Side²
Area of Square = Side × Side
Area of given Square = [5x⁴y²]²
Area of given Square = [5x⁴y²] × [5x⁴y²]
Area of given Square = [5 × 5][x⁴ × x⁴][y² × y²]
Area of given Square = [25][x⁴⁺⁴][y²⁺²]
Area of given Square = [25][x⁸][y⁴]
Area of given Square = 25x⁸y⁴
3x+6=21 what is the value of x
Answer:
[tex]3x + 6 = 21 \\ 3x = 21 - 6 \\ 3x = 15 \\ x = \frac{15}{3} \\ x = 5[/tex]
Answer: x=5
Step-by-step explanation:
step 1:
put all the coefficients on one side and all the variables on the other, 3x=21-6
step 2: solve the sides, 3x=15
step 3: divide, 3x/3= 15/3
step 4: simplify: x=5
Plzzzzzzzzzzz my marking period ends in 3 days, I’m crying plzzz help
No links please and thank you
Answer:
Step-by-step explanation:
(find the percent by multiplying the percentage, .45, by the total number of shoes = 18 shoes)
% = 45%
p = 18
w = 40
(i did 100/40 which equals to 2.5 then multiplied 2.5 by the numerator so the numerator and denominator would both be equivelant.)
18/40 = 45/100
(multiply the whole (40) by the decimal value (.45) which is equal to 18)
40 x .45 = 18
(answer)
If Ms. M has 40 pairs of shoes, 18 of those shoes are sneakers.
What is the area of this trapezoid?
Answer:
80
Step-by-step explanation:
The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time
of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn
without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15
seconds. Suppose two independent random samples, 25 of each, are taken and the mean popping times are
calculated. Let R = the popping time of a randomly selected regular-sized bag and M = the popping time of a mini-
sized bag. Which of the following best describes the standard deviation of the sampling distribution of 5-7 ?
1 second
5 seconds
25 seconds
35 seconds
Answer:
3
Step-by-step explanation:
Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.
What is Central Limit Theorem:?The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean.
here, we have,
Given,
In the question:
The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15 seconds.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 140, standard deviation of 20, sample of 4:
By the Central Limit Theorem, the distribution is approximately normal.
Mean is the same, of 140.
n = 4 , σ = 20, thus:
s = σ /√n
= 20/√4
= 10
Thus, the correct answer is:
Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.

solve for a
2a+3b=12-2(2b+a)
PLEASE SHOW WORK ILL MARK BRAINLIEST.
Answer:
a = 3 - (7/4)b
Step-by-step explanation:
Start by performing the indicated multiplication:
2a+3b=12-2(2b+a) => 2a+3b=12 - 4b - 2a
Next, combine like terms: 4a + 7b = 12
Isolate 4a by subtracting 7b from both sides:
4a = 12 - 7b
Finally, divide both sides by 4:
a = 3 - (7/4)b

These four numbers are plotted on a number line: -2/3, 5/8, -3/5, and -1/2. Which is the correct ordering on the number line from left to right?
A. -1/2, -3/5, 5/8, -2/3
B. -3/5, -2/3, -1/2, 5/8
C. -2/3, -3/5, -1/2, 5/8
D. -1/2, -3/5, -2/3, 5/8
Answer:
-2/3 ; - 3/5 ; - 1/2 ; 5/8
Step-by-step explanation:
Given that:
We could convert the numbers to decimal to obtain a better view of the values :
-2/3 = - 0.66666
5/8 = 0.625
-3/5 = - 0.6
-1 /2 = - 0.5
Negative values are always arranged first on left of a number line.
-0.66666 < - 0.6 < - 0.5 <0.625
Hence,
-2/3 ; - 3/5 ; - 1/2 ; 5/8

Simplify the expression.

There are 500 students in a school. Sara asked 100 of the students what their favorite lunch is. Out of the students surveyed 45 said pizza, 15 said burritos, 30 said hamburgers, and 10 said hot dogs. Based upon the results, how many students out of the whole school should want the items listed? (Round to the nearest whole number.) Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50 Pizza: 22500 Burritos: 7500 Hamburgers: 15000 Hot Dogs: 5000 Pizza: 125 Burritos: 125 Hamburgers: 125 Hot Dogs: 125 Pizza: 45 Burritos: 15 Hamburgers: 30 Hot Dogs: 10
Answer: Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50
Step-by-step explanation:
Since Sara asked 100 of the students for their favorite lunch but there are 500 students in a school, this means that the items listed will have to be multiplied by 5 (500/100) in order to get the number of students in the whole school that'll need the items listed. This will therefore be:
Pizza = 45 × 5 = 225
Burritos = 15 × 5 = 75
Hamburgers = 30 × 5 = 150
Hot dogs = 10 × 5 = 50
The correct option is A:
Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50
