Miguel bought a shirt for $13.95, a pair of pants for $16.87, and a hat for $7.79. What was the total amount of money Miguel spent?
Answer:
they did not pay the same rate.
2 pairs for $50
50÷2=25
Miguel spent $25 on each pair of jeans
4 pairs for $90
90÷4=22.5
Han spent $22.50 on each pair of jeans
Therefore these two did not pay the same rate.

261 feet in 405 minutes give it as a simplified fraction
Answer:
[tex]\dfrac{261}{405}[/tex] = [tex]\dfrac{29}{45}[/tex]
Step-by-step explanation:
We need to find the simplified fraction of 261 feet in 405 minutes.
It means we need to divide 261 feet and 405 minutes or it can be written as :
[tex]\dfrac{261}{405}[/tex]
We know that, 29 × 9 = 261 and 45 × 9 = 405
[tex]\dfrac{261}{405}=\dfrac{29\times 9}{45\times 9}\\\\=\dfrac{29}{45}[/tex]
Hence, the simplified fraction of the given fraction is [tex]\dfrac{29}{45}[/tex].
Ramon earns $1,625 each month and pays $53.80 on electricity. To the nearest tenth of a percent, what
percent of Ramon's earnings are spent on electricity each month?
Ramon spends
% of his earnings on electricity each month.
Answer:
3.1%
Step-by-step explanation:
53.80/1625 x 100 is 3.1
Hope this helps plz hit the crown ;D
So what you can do is divide 53.10 by 1735 to get percentage
0.0306051873 is your decimal, so move it right 2 places to get
3.06% of his money.
You asked for the nearest 10th of a percent, so you round that to
3.1%

Find the values of the variables in each right triangle.
Answer:
x = 12
y = 16
Step-by-step explanation:
Use the Pythagoras Theorem on the left triangle.
[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(x)^2=(7.2)^2+(9.6)^2\\x^2=51.84+92.16\\x^2=144\\x=\sqrt{144}\\x=12\\[/tex]
Now use the Pythagoras Theorem on the right triangle.
[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(y)^2=(12.8)^2+(9.6)^2\\y^2=163.84+92.16\\y^2=256\\y=\sqrt{256}\\y=16\\[/tex]

10 binder; 60% off; 6% tax
Answer:
I'm going to assume that the binder is $10, and that the tax is applied after the 60% off, in which case the answer is $4.24
Step-by-step explanation:
10 * 10 = 100
6 * 10 = 60
10 - 6 = 4
6 / 25 = 0.24
4 + 0.24 = 4.24
Answer: $4.24
What us the value of 6x - 3y if x = 5 and y = 1
Answer:
27!
Step-by-step explanation:
Heya! Considering that the question has already given you the values of x and y, all you are left to do is plug them back into the equation. The value of 6 multiplied by x- 5- gets you to 30. Since y is equal to 1, 3 multiplied by 1 gets you 3. 30-3 gets you to 27, so that is your answer. I hope this helped! (Please mark as branliest if I did happen to get this right. <3)
Is 12n+60 equivalent to (n + 12) x 5 + 7n
Answer: 12n + 60
Step-by-step explanation:
So first you have to distribute the 5 in the parentheses.
(5)(n + 12) = 5n + 60
5n + 60 + 7n
Then add like terms.
12n + 60
Jennifer’s mom is putting a basketball hoop on the garage. The garage door is 8 feet high. There is 7 feet of wall between the top of the garage door to the garage roof. How far down from the garage roof should the hoop be placed so that it is 10 feet above the ground?
a) 3
b) 5
c) 4
d) 2
Answer:
B
Step-by-step explanation:
Suppose that y varies directly with x, and y = 10 when x = 25.
(a) Write a direct variation equation that relates x and y.
Equation:
(b) Find y when x = 6.
y =
Answer:
Equation: y = 0.4x
y = 2.4
Step-by-step explanation:
Use the direct variation equation, y = kx, where k is a constant
Plug in x and y:
y = kx
10 = k(25)
Solve for k:
0.4 = k
So, the equation is y = 0.4x
Then, use this equation to find y when x = 6:
y = 0.4x
y = 0.4(6)
y = 2.4
A direct proportion is a proportion such that the ratio between both variables remains constant thus the given proportion will be y = 04x and the value of y at x = 6 will be 2.4.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
a)
Let's say the direct proportion as,
y = kx
Given that y = 10 when x = 25.
10 = k(25)
Solve for k,
0.4 = k
Therefore, the equation will be y = 0.4x
y = 0.4x
b)
The value of y when x = 6
y = 0.4(6)
y = 2.4

A quality control engineer is interested in estimating the proportion of defective items coming off a production line. In a sample of 100 items, 55 are defective. The lower bound of a 99% confidence interval for the proportion of defectives is ________.
Answer:
The lower bound of a 99% C.I for the proportion of defectives = 0.422
Step-by-step explanation:
From the given information:
The point estimate = sample proportion [tex]\hat p[/tex]
[tex]\hat p = \dfrac{x}{n}[/tex]
[tex]\hat p = \dfrac{55}{100}[/tex]
[tex]\hat p[/tex] = 0.55
At Confidence interval of 99%, the level of significance = 1 - 0.99
= 0.01
[tex]Z_{\alpha/2} =Z_{0.01/2} \\ \\ = Z_{0.005} = 2.576[/tex]
Then the margin of error [tex]E = Z_{\alpha/2} \times \sqrt{\dfrac{\hat p(1-\hat p)}{n}}[/tex]
[tex]E = 2.576 \times \sqrt{\dfrac{0.55(1-0.55)}{100}}[/tex]
[tex]E = 2.576 \times \sqrt{\dfrac{0.2475}{100}}[/tex]
[tex]E = 2.576 \times0.04975[/tex]
E = 0.128156
E ≅ 0.128
At 99% C.I for the population proportion p is: [tex]\hat p - E[/tex]
= 0.55 - 0.128
= 0.422
Thus, the lower bound of a 99% C.I for the proportion of defectives = 0.422
if 4(x-1)=8(x-2),then x=
4(x-1)=8(x-2)
multiply the first bracket by 4
(4)(x)=4
(4)(-1)=-4
multiply the second bracket by 8
(8)(x)=8x
(8)(-2)=-16
4x-4=8x-16
move 8x to the other side ( in other words combine like terms)
sign changes from +8x to -8x
4x-8x-4=8x-8x-16
-4x-4=-16
move -4 to the other side
-4x-4+4=-16+4
-4x=-12
divide both sides by -4 to get x by itself
-4x/-4=-12/-4
x=3
answer:
x=3
Answer:
x = 3
Step-by-step explanation:
4( x - 1) =8
4x - 4 = 8
+ 4 + 4
4x = 12
x = 3
8 ( x - 2 )
8 ( 3 - 2 )
24 - 16
= 8
