Suppose you have a pocketful of change. You have some pennies (p) and some quarters (q). One expression could be used to describe the total number of coins in your pocket: p + q. A second expression could be used to describe the amount of money (in dollars) in your pocket: 0.01p + 0.25q. Notice that each expression describes a different characteristic of the change in your pocket. Evaluate each expression for the situation where you have 6 quarters and 7 pennies in your pocket. Type the correct answer in each box. Use numerals instead of words. For the amount of money, do not enter a dollar symbol.
Answer:
13
1.57
Step-by-step explanation:
So we have two equations regarding the number of quarters q and the number of pennies p:
[tex]p+q[/tex]
Which represents the total amount of coins and
[tex]0.01p+0.25q[/tex]
Which represents the total amount of money in dollars.
So we are asked to evaluation each expression for the situation in which we have 6 quarters and 7 pennies. Thus, plug 6 in for q and 7 in for p:
[tex]p+q\\(7)+(6)=13[/tex]
This tells us that we have 16 coins in total.
[tex]0.01(7)+0.25(6)\\=0.07+1.50\\=1.57[/tex]
This tells us that we have a total amount of $1.57.
Answer:
[tex]\Large \boxed {13} \\ \boxed{ 1.57}[/tex]
Step-by-step explanation:
Pennies ⇒ [tex]p[/tex]
Quarters ⇒ [tex]q[/tex]
First expression describes the total number of coins in the pocket ⇒ [tex]p+q[/tex]
Second expression describes the amount of money in dollars in the pocket ⇒ [tex]0.01p+0.25q[/tex]
There are 6 quarters and 7 pennies in the pocket.
First expression :
[tex]p+q \\ 7 + 6 = 13[/tex]
Second expression :
[tex]0.01p+0.25q \\ 0.01(7)+0.25(6) \\ 0.07+1.5 =1.57[/tex]

The winning car in a race beat the second car by 19 ··· 100 of a second. The third car was ·4· 10 of a second behind the second car. By how much did the first car beat the third car?
Add the times together:
19/100 + 4/10
Find the common denominator, which is 100 so rewrite 4/10 as 40/100
Now add:
19/100 + 40/100 = 59/100
The first car beat the third car by 59/100 seconds.
please help me on this geometry
Answer:
x = 30
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , thus
x + 4x + 30 = 180
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30

Johnny’s vegetable garden is rectangular. The length of the garden is 2x-1 and the width of the garden is 3x+2. Find the Perimeter and Area of the garden.
Answer:
[tex] \boxed{\sf Perimeter \: of \: rectangular \: garden = 10x + 2} [/tex]
[tex] \boxed{\sf Area \: of \: rectangular \: garden = 6x^2 + x - 2} [/tex]
Given:
Length of rectangular garden = 2x - 1
Width of rectangular garden = 3x + 2
Step-by-step explanation:
[tex] \sf Perimeter \: of \: rectangular \: garden = 2(Length + Width)[/tex]
[tex] \sf = 2((2x - 1) + (3x + 2))[/tex]
Grouping like terms:
[tex] \sf = 2((2x + 3x) + (2 - 1))[/tex]
2x + 3x = 5x:
[tex] \sf = 2(5x + (2 - 1))[/tex]
2 - 1 = 1:
[tex] \sf = 2(5x + 1)[/tex]
[tex] \sf = (2 \times 5x) + (2 \times 1)[/tex]
2 × 5x = 10x:
[tex] \sf = 10x + (2 \times 1)[/tex]
2 × 1 = 2:
[tex] \sf = 10x + 2[/tex]
[tex] \therefore[/tex]
Perimeter of rectangular garden = 10x + 2
[tex] \sf Area \: of \: rectangular \: garden = Length \times Width[/tex]
[tex] \sf = (2x - 1)(3x + 2)[/tex]
[tex] \sf = 2x(3x + 2) - 1(3x + 2)[/tex]
[tex] \sf = (2x \times 3x) + (2x \times 2) - (1 + 3x) - (1 \times 2)[/tex]
2x × 3x = 6x²:
[tex] \sf = 6 {x}^{2} + (2x \times 2) - (1 + 3x) - (1 \times 2)[/tex]
2x × 2 = 4x:
[tex] \sf = 6 {x}^{2} + 4x - (1 + 3x) - (1 \times 2)[/tex]
1 × 3x = 3x:
[tex] \sf = 6 {x}^{2} + 4x - 3x - (1 \times 2)[/tex]
1 × 2 = 2:
[tex] \sf = 6 {x}^{2} + (4x - 3x) - 2[/tex]
4x - 3x = x:
[tex] \sf = 6 {x}^{2} + x - 2[/tex]
[tex] \therefore[/tex]
Area of rectangular garden = 6x² + x - 2
Answer:
Perimeter = 10x+2 m
Area = 6x²+x-2 m²
Step-by-step explanation:
Length of garden (l) = 2x-1
width or breadth of garden ( b) = 3x+2
Now,
Perimeter of the garden (p) = 2( l + b)
= 2 ( 2x-1 + 3x+2 )
= 2 ( 5x + 1 )
= 10x+2 m. ( Answer )
Again,
Area of garden (a) = l * b
= ( 2x-1 ) ( 3x+2 )
= 2x ( 3x+2 ) -1 ( 3x+2 )
= 6x² + 4x - 3x - 2
= 6x²+x-2 m². ( Answer )

Step-by-step explanation:
Distance = 2 1/2 = 2.5 milesSpeed = 4 miles/hour = 4 miles / 60 minutesTime = ?Time = distance/speed:
2.5 miles ÷ 4 miles / 60 minutes =2.5 miles × 60 minutes / 4 miles =37.5 minutesCorrect answer choice is:
A. 2.5 miles divided by 4 miles/hour divided by 60 minutes/ hourThree times the sum of half a number and 7 is 36
Answer:
your answer is 19.34
Step-by-step explanation:
let the number be x
half a number = ½ x
three times means multiplied by three
so,
3( ½ x) + 7 = 36
3( ½ x) = 36 - 7
3( ½ x) = 29
½ x = 29/3
½ x = 9.67...
x = 9.67 × 2 (when we moved ½ on the other side of the equal sign it › turns into 2/1 )
x = 19.34

A number that is bigger than 5 2/3 but smaller than 6 could be 5.7.
A number that is bigger than 5.6 but smaller than 5 2/3 could be 5.62.
Hope this helps!
In fact 5 2/3 means 5+2/3 for this. So,5+2/3 = 17/3 = 5.6
For first question, if "numbers" are also include rational numbers, you can write any rational number according to this interval. For example, 5.7 , 5.75, 5.9
But the second one, the interval that is shown us has the same value 5.6 and 5.6. So you cannot find a number which should bigger 5.6 and smaller 5.6 . It seems impossible I mean.

Paj is filling a 9-cubic-inch flower pot with soil from small bags. Each bag of soil contains 2 2/3 cubic inches of soil. Exactly how many bags of soil are needed for Paj to fill the flower pot?
Answer:
Exactly 3 3/8 bags of soil are needed for Pan to fill the flower pot
Step-by-step explanation:
Here in this question, we are concerned with calculating the number of bag of soils with a given volume each needed to fill a flower pot with soil.
What we simply need to do here is to divide the volume of the flower pot with the volume of the individual bag of soils;
Mathematically, that would be;
9 divided by 2 2/3
= 9 divided by 8/3
= 9 * 3/8 = 27/8 = 3 3/8 bag of soils

Item 15 Question 1 Write and solve an equation to answer the question. The perimeter of the Norwegian flag is 190 inches. What are the dimensions of the flag? Equation: =190 y= Question 2 Label the dimensions of the flag in inches.
Answer:
40 inches by 55 inches.Step-by-step explanation:
The question lacks the required diagram. Find the diagram in the attachment.
The flag is rectangular in nature and the formula for calculating the perimeter of a rectangle is P = 2(L+W) where;
L is the length of the flag
W is the width of the flag
From the diagram, L = y and W = 11y/8
Since the perimeter = 190 inches, we will substitute the given parameters into the formula and firs calculate the value of y.
190 = 2(y+11y/8)
190 = 2y + 11y/4
multiply through by 4
760 = 8y+11y
760 = 19y
y = 760/19
y = 40
The length of the flag is 40 inches and the Width of the flag is 11(40)/8 = 55inches.
Hence, the dimensions of the flag in inches is 40 inches by 55 inches.
