Answer:
28 hats
Step-by-step explanation:
We can solve this using a system of equations:
14.95s + 12.95h = 1588.50
s + h = 110
Let's isolate the shirt variable in the second equation:
s + h = 110
s = -h + 110
Now that we have isolated s we can plug it back into the first equation:
14.95(-h + 110) + 12.95h = 1588.50
Solve for h
-14.95h + 1644.5 + 12.95h = 1588.50
-2h + 1644.5 = 1588.50
-2h = -56
h = 28
The football team sold a total of 28 hats.
Hope this helps!!

The number of hats did they sell should be considered as the 28 hats when the received amount is given.
Calculation of the number of hats:Since
The football team had a fundraiser .
They received $1588.50 from the sale of 110 shirts and hats .
shirts sold for 14.95 each. hats sold for 12.95 each .
So, the following equations are applied
14.95s + 12.95h = 1588.50
s + h = 110
We can write like
s = -h + 110
Now
14.95(-h + 110) + 12.95h = 1588.50
-14.95h + 1644.5 + 12.95h = 1588.50
-2h + 1644.5 = 1588.50
-2h = -56
h = 28
Hence, The football team sold a total of 28 hats.

Step-by-step explanation:
The formula to find the area of a rectangular prism is A = 2 (wl + hl + hw)
Substitute the values:
A = 2 (5x5 + 3x5 + 3x5)
A = 2 (25 + 15 + 15)
A = 2 (25 + 15 + 15)
A = 2 (55)
A = 110
Anthony's little brother gets on a carousel that is 8 meters in diameter. At the start of the ride, his brother is 3 meters from the fence to the ride. How far will his brother be from the fence after the carousel rotates 240°?
Answer:
9 m
Step-by-step explanation:
Given that:
Carousel diameter = 8m
Radius of carousel = 8m / 2 = 4m
From the attached picture :
xo = d ; from the diagram attached ;
Using Pythagoras :
Cosθ = Adjacent / hypotenus
Cos 60 = d / 4
0.5*4 = d
d = 2
d = 2m
d + length of Radius + initial distance from fence
2m + 4m + 3m = 9m

7.) x = 21
8.) y = 6
9.) angle F = 62 degrees
10.) TS = 10
Step-by-step explanation:
5y-2 = 28
5y = 30
y = 6
4x+6 = 90
4x = 84
x = 21
angle F = 90-28

Ivan and Tanya share £150 in the ratio 4: 1
Work out how much more Ivan gets compared to Tanya.
Answer:
Ivan got £90 more than Tanya.
Step-by-step explanation:
Ivan and Tanya share the amount £150 in the ratio of 4 : 1
Amount received by Ivan = [tex]150\times \frac{4}{(4+1)}[/tex]
= [tex]150\times \frac{4}{5}[/tex]
= £120
Similarly, amount received by Tanya = [tex]150\times \frac{1}{(4+1)}[/tex]
= £30
Difference in their amounts = 120 - 30
= £90
Therefore, Ivan got £90 more than Tanya.

Tina went out to eat and her bill was $24.75.
She wants to leave the waiter a 20% tip. How
much more money will be added to her bill
once she included the tip?
Answer:
your awnser should be. 24.75 + 20% = $29.70
so the amount added to her bill is $4.95
Answer:
the bill will be 4.95 more than the original cost without the 20% tip.
Step-by-step explanation:
cost before tip: 4.75
cost after 20% tip: 29.70 or 30.00 (rounded)
Two mechanics worked on a car. The first mechanic charged $115 per hour, and the second mechanic charged $65 per hour. The mechanics
combined total of 15 hours, and together they charged a total of $1475. How long did each mechanic work?
Answer:
Here is another case where we have two unknowns (the number of hours each mechanic worked) so we'll need two equations to solve.
Let A = number of hours first mechanic worked (the one who charged $45/hour)
Let B = number of hours second mechanic worked (the one who charged $105/hour)
From the problem statement, we know that the two mechanics worked a combined 35 hours so the first equation is:
Equation 1: A hours + B hours = 35 hours
We also know that in total, the charge was $2475. So the second equation is:
Equation 2: (A hours x 45 dollars/hour) + (B hours x 105 dollars/hour) = 2475 dollars
So our two equations are:
1: A + B = 35
2: 45A + 105B = 2475
Multiply both sides of the first equation by -45 to get the following:
-45A - 45B = -1575
Now the two equations are:
1: -45A - 45B = -1575
2: 45A + 105B = 2475
Add them together and the "A" term drops out:
-45B + 105B = -1575 + 2475
or
60B = 900
Now divide both sides by 60:
B = 15
Now plug B = 15 into the first equation:
A + 15 = 35 thus A = 20
So Mechanic A (at $45/hour) worked 20 hours and Mechanic B (at $105/hour) worked 15 hours
Check: 20x45 + 15x105 = 900 + 1575 = 2475

The Large Counts Condition must be met so that the sampling distribution of a sample proportion is approximately normal. Using appropriate notation, write out the Large Counts Condition for Normality.
Answer:
np>10 and n(1-p)>10
Step-by-step explanation:
Appropriate notation the Large Counts Condition for Normality is The Large Counts Condition for Normality states that is the number of successes and failures which should be above the 10 to be assume normality that is here express as n(p)>10 and n(1-p)>10 This is the notation of the Large Counts Condition for Normality.The Large Counts Condition for Normality: np ≥ 10 and nq ≥ 10.
The Large Counts Condition, also known as the Large Sample Size Condition, is a requirement that must be met to ensure that the sampling distribution of a sample proportion is approximately normal when sampling from a population. This condition is necessary to apply the normal distribution to the sample proportion for various statistical inferences.
Let's denote the following:
- n: The sample size, i.e., the number of observations in the sample.
- p: The population proportion of the characteristic of interest.
- q: The complementary probability to p, such that q = 1 - p.
The Large Counts Condition for Normality states:
np ≥ 10 and nq ≥ 10
In other words, the product of the sample size (n) and the population proportion (p) must be greater than or equal to 10, and the product of the sample size (n) and the complementary probability (q) must also be greater than or equal to 10.
When both of these conditions are satisfied, the sampling distribution of the sample proportion can be approximated by a normal distribution. This approximation is useful for constructing confidence intervals and performing hypothesis tests related to proportions.

Ben has $19 to spend. He spent $7.25, including tax, to buy a notebook. He needs to save $2.75 but he wants to buy a snack. If pretzels cost $0.50 per package including tax, what inequality would show the maximum number of packages that Ben can buy?
PLS HELP ASAP:
- what is the INEQUALITY FOR THIS PROBLEM. THAT'S ALL IM ASKING. DON'T SOLVE IT.
Answer:
($19 - $7.25) - $2.75 ÷ (0.50p) ≤ 19
Step-by-step explanation:
First, let's define the variable:
p = pretzel packages
Let's first find out how much money Ben has after buying the notebook.
$19 - $7.25 = $11.75
So, we know that Ben has $11.75 left.
The inequality would be: ($19 - $7.25) - $2.75 ÷ (0.50p) ≤ 19
Find C and a so that f(x) = CaX models the situation described. State what the variable x represents in your formula. In 2000 a house was worth $220,000, and its value decreases by 11% each year thereafter. please help im failing
Answer:
f(x) = Ca^x
x = years since 2000.
f(0) = 220000 = Ca^0 = C
f(x) = 220000a^x
f(1) = 220000(1-0.11) = 220000a^1
a = 0.89
f(x) = 220000(0.89)^x
So each year reduces by 89%
