Bob has $3.69 in pennies, dimes, and quarters. The number of pennies is three more than the number of dimes. The number of quarters is twice the number of dimes. How many of each coin does he have?
Answer:
9 pennies, 6 dimes, 12 quarters.
Step-by-step explanation:
Pennies = $0.01
Dimes = $0.10
Quarters = $0.25
Let x be the number of dimes. Then (x + 3) is the number of pennies and 2x is the number of quarters.
We have x($0.10) + (x + 3)($0.01) + 2x($0.25) = $3.69
x($0.10) + (x + 3)($0.01) + 2x($0.25) = $3.69
$0.1x + $0.01x + $0.03 + $0.5x = $3.69
$0.61x = $3.66
x = 6.
Therefore Bob has 9 pennies, 6 dimes and 12 quarters.

solve for x in this equation A=Bxt+C
Answer:
[tex]x = \frac{A - C}{Bt} [/tex]Step-by-step explanation:
A = Bxt + C
To solve for x move C to the other side of the equation
That's
Bxt = A - C
Divide both sides by Bt to make x stand alone
That's
[tex] \frac{Bxt}{Bt} = \frac{A - C}{Bt} [/tex]We have the final answer as
[tex]x = \frac{A - C}{Bt} [/tex]Hope this helps you

Question 5 (25. pts)
What can you conclude about your observations in Question 4? What happened as you moved P, the center of rotation, about the coordinate plane? How can you extend your discoveries about the vertices to all points that lie on a figure or shape?
Answer:
No matter where the center of rotation is located on the coordinate plane, each point in the preimage is the same distance from the point of rotation as its corresponding point in the rotated images. This distance is not affected by changing the location of P. Although this investigation covered vertices only, it's clear that any point on a shape or figure will be affected similarly.

The average distance from Earth to the sun is about 9.3 x 10LaTeX: ^77 miles. The average distance from Mars to the sun is about 1.4 x 10LaTeX: ^88 miles. When both planets are at their average distance from the sun, how much farther is Mars from the sun than Earth?
Answer:
Mars is [tex]1.4 \times 10 ^{88} miles[/tex] farther from the sun than Earth?
Step-by-step explanation:
We can assume that the two planets are on a straight line. This would make the solution easier for us.
The average distance from Earth to the sun is about [tex]9.3 \times 10 ^{77} miles[/tex]
The average distance from Mars to the sun is about [tex]1.4\times 10^{88} miles[/tex]
To find how much farther is Mars from the sun than Earth, we simply need to subtract the distances between the Earth and the Sun and the Distance between Mars and the Sun.
This will be
[tex]1.4\times 10^{88} miles[/tex] - [tex]9.3 \times 10 ^{77} miles[/tex] = [tex]1.4 \times 10 ^{88} miles[/tex]
(25 POINTS!!!!) a rectangular garden measures 5 feet by 4 feet. The length and width are both increased by the same amount and the new area is 56 square feet. What are the new dimensions of the garden?
The new dimensions of the garden are 8 feet and 7 feet.
What is rectangle?A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.
Given that,
The length of rectangular garden = 5 feet,
And the width of rectangular garden = 4 feet.
The area of rectangular garden = 5 x 4 = 10 square feet.
Let the length and width are increased by x feet, to make the new area 56 square feet.
The new length = 5 + x,
and new width = 4 + x.
The area = 56
(5 + x) × (4 + x) = 56
Substitute, x= 3 which satisfies the equation,
So, the new length of garden = 5 + 3 = 8 feet,
And the new width of garden = 4 + 3 = 7 feet.

The world record for the most number of speed skips in 60 seconds is 332 skips. If the record holder skipped at a constant ratio of seconds to skips, how many skips did she make in 15 seconds?
Answer:
83
Step-by-step explanation:
If that number of skips is represented by s, we can write the proportion ...
skips/seconds = s/15 = 332/60
s = 332(15/60) = 332/4 = 83
She skipped at the rate of 83 skips in 15 seconds.
_____
Additional comment
If the ratio seconds : skips is constant, then so will be the ratio skips : seconds.
Answer:
332/60 is 5.53, then multiply that by 15 and your answer is 83

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 0.875}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{3[ x + 3(4x - 5)] = 15x - 24}[/tex]
Distribute 3 through the parentheses
⇒[tex] \sf{3[ x + 12x - 15 ] = 15x - 24}[/tex]
Collect like terms : 12x and x
⇒[tex] \sf{3[ 13x - 15 ] = 15x - 24}[/tex]
Distribute 3 through the parentheses
⇒[tex] \sf{39x - 45 = 15x - 24}[/tex]
Move 15x to left hand side and change it's sign
Similarly, move 45 to right hand side and change it's sign
⇒[tex] \sf{39x - 15x = - 24 + 45}[/tex]
Collect like terms
⇒[tex] \sf{24x = - 24 + 45}[/tex]
Calculate
⇒[tex] \sf{24x = 21}[/tex]
Divide both sides of the equation by 24

We going to do this process in a stepwise manner
given the expression
18=6(2x – 8)
1. open bracket on the left-hand side (distributive property)
18=12x-48
2. collect like terms
18+48=12x
66=12x
3. divide both sides by 12 we have
x= 66/12
x= 33/6
x=11/2

Step-by-step explanation:
Given:
cos²27°×cos²34°×...×cos²167 = ?Looking at the angles measures, they form series of:
27, 34, 41, ..., 167This is AP with the first term of 27 and common difference of 7
We can see one of the terms of this AP is 90
27+9*7 = 27 + 63 = 90Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.
So correct answer choice is Option 4) 0

25cg : 4g in lowest terms.
Step-by-step explanation:
We need to convert 25 cg : 4g in lowest terms.
We know that, 1 gram = 100 centigram
1 cg = (1/100) gram
25 cg = [tex]\dfrac{25}{100}[/tex] grams
To write 25 cg : 4g in lowest terms, the step to be done are as follows :
[tex]\dfrac{25\ cg}{4\ g}=\dfrac{\dfrac{25}{100}}{4}\\\\=\dfrac{\dfrac{25}{25\times 4}}{4}\\\\=\dfrac{1}{16}[/tex]
It means that the lowest term for 25 cg : 4g is [tex]\dfrac{1}{16}[/tex]
