Hope this helps! :)
Have a blessed day and remember to keep smiling! :)
[tex][Hello,BrainlyUser][/tex]
Answer:
32 Yards
Step-by-step explanation:
Given;
Length of fabric required for each costume = 2 2/3
Total number of costumes to be made =12
Solve;
12 * 2 2/3
We can multiply mixed numbers by converting it to fractions.
⇒ 12 * 8/3
⇒ 32
Thus, you need 32 yards of fabric.

When Amira goes bowling, her scores are normally distributed with a mean of 160
and a standard deviation of 13. What percentage of the games that Amira bowls does
she score less than 192, to the nearest tenth?
Using the normal distribution, it is found that she scores less than 192 in 99.3% of games.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by [tex]\mu = 160, \sigma = 13[/tex].
The proportion of games in which she scores less than 192 is the p-value of Z when X = 192, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{192 - 160}{13}[/tex]
[tex]Z = 2.46[/tex]
[tex]Z = 2.46[/tex] has a p-value of 0.993.
Hence, she scores less than 192 in 99.3% of games.

Jaime ran the first 3 1/3 miles of a 5-mile race in 1/3 hour. What was her average rate, in miles per hour, for this first part of the race? Explain how you solved the problem.
9514 1404 393
Answer:
10 mph
Step-by-step explanation:
To find miles per hour, divide miles by hours:
(3 1/3 mi)/(1/3 h) = (10/3)/(1/3) mi/h = 10 mi/h
Jaime's average rate was 10 miles per hour.

if a certain cannon is fired from a height of 8.5 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time, t, In seconds, is found by the function h(t)=-4.9t^2+27.5t+8.5 Find the time it takes for the cannonball to strike the ground.
Answer: 2.88 seconds
Step-by-step explanation:
we need to find t in the formula, when h(t) = 0, (meaning it hits the ground).
0 = -4.9t² + 27.5t + 8.5
Using the quadratic formula:
x = (-b ± √b² - 4ac)/2a
x = (-27.5 ± √27.5² - 4(-4.9)(8.5))/2(27.5)
x = (-27.5 ± 30.38)/55
x = 2.88 OR x = -57.88
Since time cannot be negative, we will stick with the positive answer, 2.88 seconds.

Answer: $2,728.40
Step-by-step explanation:
The starting value is: $17,000
the rate of deprecation is: 12.25%
time = 14 years
Lets plug this into the interest formula:
Cost after 14 years = Principle(1 - r)^t
Cost after 14 years = 17,000(1 - 0.1225)^14
Cost after 14 years ≅$2,728.40
Deprecation happens pretty quickly!
Are the following equations perpendicular y=-1/3x+4 and y=1/3x+12?
Explanation:
Compare each equation to the form y = mx+b
m = slope
The first equation has slope -1/3 and the second equation has slope 1/3
The slopes do not multiply to -1, so the lines aren't perpendicular.
The slopes aren't equal, so the line aren't parallel either.

Answer:
180 cm²
Step-by-step explanation:
From inspection of the diagram, the surface area is made up of the area of 4 congruent triangles and the area of one square.
Area of a square = x² (where x is the length of one side)
⇒ area of the square = 6² = 36 cm²
Area of a triangle = 1/2 x base x height
⇒ area of one triangle = 1/2 x 6 x 12 = 36 cm²
Total surface area = 4 x area of one triangle + area of the square
= 4 x 36 + 36
= 144 + 36
= 180 cm²
Answer:
180 I was the first so could I have brainlyest
Step-by-step explanation:
we need the area of 4 triangles and one square triangle = base x height x 1/2 square = base x height 6 x 6 = 36 + ( 6 x 12 / 2 x 4 = 144) = 180
What is the slope of the line that passes through the points (2, 9)(2,9) and (18, -3)(18,−3)? Write your answer in simplest form.
(2 ; 9) and (18 ; - 3)
slope = (-3 - 9) / (18 - 2) = -12/16 = -3/4 or - 0,75
Slope of the line that passes through the points (2, 9) and (18, -3) is -2.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b
where m is the slope and b is y intercept.
The formula to calculate slope passing through two points (x1, y1) and (x2, y2) is
m= (y₂- y₁)/(x₂-x₁)
The given two points are (2, 9) and (8, -3)
Here x₁=2, y₁=9, x₂=8, and y₂=-3
Substitute the values in formula of slope.
m=-3-9/8-2
m=-12/6
m=-2
Hence slope of the line that passes through the points (2, 9) and (18, -3) is -2.

I spent $4.80 on groceries and $1.20 on vegetables. What is the ratio of:
a. Cost of groceries to cost of vegetables;
b. Cost of vegetables to cost of groceries;
c. Cost of vegetables to total cost;
d. Cost of groceries to total cost?
Help me plz
The required ratio is given as a) 4/1 b) 1/4 c) 1/5 and d) 4/5.
Given that,
Spent $4.80 on groceries and $1.20 on vegetables.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Total cost = 4.80 + 1.20
Total cost = $6.00
a. Cost of groceries to cost of vegetables;
Ratio = 4.80 / 1.20 = 4 / 1
b. Cost of vegetables to cost of groceries;
Ratio = 1.20 / 4.80 = 1 / 4
c. Cost of vegetables to total cost;
Ratio = 1.20 / 6 = 1 / 5
d. Cost of groceries to total cost
Ratio = 4.80 / 6 = 4 / 5
Thus, the required ratio is given as a) 4/1 b) 1/4 c) 1/5 and d) 4/5.

If f(-4) for f(x)=-2x+7 is 15, then what is f^-1 (15)?
let's recall that for a function f(x) that has an inverse function f⁻¹(x), the domain of f(x) corresponds to the range of f⁻¹(x), what the heck does that all mean?
well, it means that for any coordinate pairs (a , b) in f(x), there's a corresponding pair of (b , a) on f⁻¹(x).
we know in this case that f(-4) = 15, or namely that f(x) has a pair of (-4 , 15), well, that means that f⁻¹(x) has a swapped pair of (15 , -4).
the above means that f⁻¹(15) = -4.
y=-3x^2-24x-42 in vertex form
Answer:
Step-by-step explanation:
y = - 3x² - 24x - 42
y = - 3( x² + 8x + 14 )
y = - 3( x² + 2·4·x + 16 - 16 + 14 )
y = - 3[ ( x + 4 )² - 2 ]
y = - 3( x + 4 )² + 6

True or False. A function is increasing if its outputs get larger as the inputs
get larger.*
Answer:
True
Step-by-step explanation:
A function is increasing if its outputs get larger as the inputs is a "true statement" or the first option. If the inputs are getting larger for every input and the outputs are getting larger for every output, if you plot the data on a scatter plot or a coordinate plane of sorts you would see it take shape of a line that is moving from the left to the top right which means the function is indeed increasing when the outputs/inputs get larger.
