Jillian is making accessories for the soccer team. She uses 761.78 inches of fabric on headbands for 39 players and 2 coaches. She also uses 331.89 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
Head bands: 18.58 inches of fabric
Wrist bands : 8.51 inches of fabric
Step-by-step explanation:
Jillian is making accessories for the soccer team.
For head bands
She uses 761.78 inches of fabric on headbands for 39 players and 2 coaches.
The total number of people = 39 player + 2 coaches = 41 people
Hence:
41 persons = 761.78 inches of fabric
1 person = x
Cross Multiply
41 × x = 761.78 × 1
x = 761.78/48
x = 18.58 inches
For wristbands
She also uses 331.89 inches of fabric on wristbands for just the players.
Number of players = 39 players
Hence:
39 players = 331.89 inches
1 players = x inches
Cross Multiply
39 × x = 1 × 331.89 inches
x = 331.89 inches/39
x = 8.51 inches
Therefore:
18.58 inches of fabric was used for head bands and 8.51 inches of fabrics was used for wristbands.
Which is an equivalent equation solved for t?
O te fry
O tufa
O t= a(f - V)
O t = v(f – a)
Answer:
[tex]\dfrac{v-u}{a}[/tex]
Step-by-step explanation:
The given equation should be:
v = u +at ...(1)
Where
u is initial velocity, v is final velocity, a is acceleration and t is time
We need to solve the above equation for t.
Subtract u from both sides.
v-u= u +at -u
v-u=at
Dividing both sides by a.
[tex]\dfrac{v-u}{a}=\dfrac{at}{a}\\\\t=\dfrac{v-u}{a}[/tex]
So, the expression for t is equal to [tex]\dfrac{v-u}{a}[/tex].
Katie and Sunnie both have 20-gallon fish tanks that are leaking water! After 15 minutes, Katie's tank has leaked 43 gallon. After 20 minutes, Sunnie's tank has leaked 34 gallon. Which tank is leaking faster?
Answer:
Katie's gallon
Step-by-step explanation:
Katie and Sunnie both have 20-gallon fish tanks that are leaking water!
For Katie
After 15 minutes, Katie's tank has leaked 4/3 gallon.
The rate of leakage =
4/3 gallon × 15 minutes
= 16
For sunny
After 20 minutes, Sunnie's tank has leaked 3/4 gallon.
Her rate is given as:
= 3/4 gallon × 20 minutes
= 15
Therefore,
The tank that is leaking faster is Katie's gallon

A researcher compared the heights and shoe sizes for 50 men, selected at random. The equation shown describes a line of best fit for the data, where x is the shoe size and y is the height, in inches. y equals 1.6 x plus 48 Question Based on the equation, what is the approximate shoe size for a man having a height of 60 inches? Answer options with 4 options
Answer:
7.5
Step-by-step explanation:
From the above Question, the equation is given as:
y = 1.6x + 48
Where
x is the shoe size
y is the height, in inches.
What is the approximate shoe size for a man having a height of 60 inches?
This is calculated as:
60 = 1.6x + 48
Collect the like terms
1.6x = 60 - 48
1.6x = 12
We divide both sides by 1.6
x = 12/1.6
x = 7.5
Therefore, the shoe size for a man having the height of 60 inches is 7.5.

A property dealer charges a commission of 2% on the first 25000 and 1.5 % on the remainder. What commission does he charge for selling a plot of land of 130000
Answer:
$2075
Step-by-step explanation:
commission = 0.02 x $25,000 = $500
The remainder = $130,000 - $25,000 = $105,000
Commission on the remainder = 0.015 x $105,000 = $1,575
Total commission = $1,575 + $500 = $2075

Triangle ABC is similar to triangle DEF
Answer:
A my dude. good luck!!!!!
Answer:
A
Step-by-step explanation:
AC = 5
DF = 15
5 x 3 = 15
BC = 3
EF = 9
3 x 3 = 9
Do you see the pattern? So as you can see the difference between Triangle ABC and DEF is the multiply/divide 3 so if you want to find DE then you should set it up as:
[tex]\frac{4}{3}[/tex] = [tex]\frac{DE}{9}[/tex] and to check if its right if you solve it you get [tex]\frac{4}{3}[/tex] = [tex]\frac{12}{9}[/tex]
and as you see [tex]\frac{12}{9}[/tex] and [tex]\frac{4}{3}[/tex] are literally the same thing just you need to simplify [tex]\frac{12}{9}[/tex]
Which equation can be used to find the value for X?
Answer:
(3x-5) + 2x = 90
Step-by-step explanation:
We know that there are 180 degrees in a triangle. We also know that one angle is 90 degrees.
This means that (3x-5) + 2x = 90.
So can someone just help me solve this and tell me which terms belong together....ty-

the significance level of the testn equilateral triangle is 6 cm. What is the height of the triangle?
Answer: D) the significance level of the test
=======================================================
Explanation:
The significance level of the test, also known as "alpha", is the probability of making a type 1 error. A type 1 error is where you reject the null hypothesis but it was true all along.
The null hypothesis is where we test a certain probability distribution (eg: normal distribution). Specifically we gather a sample of values and compute the test statistic. If the probability of getting that test statistic or more extreme is smaller than alpha, then we reject the null. This probability value is known as the p-value.
If you lower the alpha value, then that will make it more likely you do not reject the null. Consider an example where alpha = 0.10 to start with. If you get a p-value of 0.02, then you would reject the null. The same would apply for alpha = 0.05; however, with alpha = 0.01, the p-value is no longer smaller than alpha. At this point we do not reject the null. Your textbook may use the phrasing "fail to reject the null".
Going in the opposite direction, increasing the alpha value will make it more likely to reject the null. Each time you adjust the alpha value, keep the p-value to some fixed number (between 0 and 1).
The height of the equilateral triangle is 3√3 cm.
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
To minimize the probability of incorrectly rejecting the null hypothesis in a hypothesis test with a fixed sample size of 40, the statistician can adjust the significance level of the test.
The significance level, denoted by α, is the probability of rejecting the null hypothesis when it is actually true.
By choosing a smaller significance level, the statistician can decrease the probability of making a Type I error (rejecting the null hypothesis when it is actually true).
However, decreasing the significance level also increases the probability of making a Type II error (failing to reject the null hypothesis when it is actually false).
Therefore,
The choice of significance level involves a trade-off between the two types of errors and should be based on the specific context of the problem and the consequences of each type of error.
Now,
The height of an equilateral triangle can be found using the formula:
height = (side length / 2) x √3
The side length = 6 cm
So,
height = (6 / 2) x √3
= 3√3 cm
Therefore,
The height of the equilateral triangle is 3√3 cm.
