Answer:

8 dimes

Step-by-step explanation:

A quarter is $0.25, so 0.25 should be multiplied by the number of quarters she has:

0.25 * 12 = 3.00

A nickel is $0.05, so 0.05 should be multiplied by the number of nickels she has:

0.05 * 7 = 0.35

If we add this together, we get 3.35, and the rest of the money Courtney has is in dimes. First, find the amount of money left:

4.85 - 3.35 = 1.50

A dime is $0.10, so divide the amount of money left by 0.10 to find the number of dimes Courtney has:

1.50 ÷ 0.10 = 15

Subtract 15 by the number of nickels Courtney has to find how many more dimes she has than nickels:

15 - 7 = 8 dimes

b one root is negative of the other root

Answer:

Multiply both the divisor and the dividend by 10 to make it easier to divide

Step-by-step explanation:

As given division equation in a more suitable format that shows the dividend and the divisor that is = [tex]\frac{5.72}{0.52}[/tex]

so now we we will make the two parts to be whole number

first factor to muliply both dividend and divisor by is looking at their decimal place as they both have two decimal places

so, that we multiplying both of them by a 10 will make them whole numbers

so so correct answer is 10

[tex]\frac{5.72\times 10}{0.52 \times 10} =[/tex]  11

Answer:

  4, 5, 6, maybe 2

Step-by-step explanation:

You're looking for values strictly between 6 and 7. In decimal, the number will have a leading digit of 6 and a non-zero decimal fraction.

1. √36 = 6 . . . out of range

2. 2πr ≈ 6.28r . . . value depends on r (presumed not in range)*

3. 14/2 = 7 . . . out of range

4. 1/0.15 ≈ 6.666...(repeating) . . . in range

5. 25/4 = 6.25 . . . in range

6. tan(81°) ≈ 6.31... . . . in range

____

* of course, 2π will be in range.

Answer:

about 48 miles a week

Step-by-step explanation:

2500 divided by 52 (number of weeks in a year)=

625 divided by 13=  48.076923

about 48 miles

Answer:

The answer is is 48.1 miles Every week

Step-by-step explanation:

We know that there are 52 weeks in the year and beyond 2500 mpt now we can calculate the number of miles that are conducted every week through

[tex] \frac{2500}{52} = 48.1 \:[/tex]

Answer:

100

Step-by-step explanation:

mode : the most common number that appears

Answer:

100

Step-by-step explanation:

The mode is the number that is repeated the most. In this case, 100 is the only number that is repeated, and therefore it is the mode.

Answer:

x = 17, -3

Step-by-step explanation:

I'm not sure why this is the answer I only know because I've had it before

pretty sure you have to use (b/2) ^2

The complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.

Rearranging the equation x² - 51 = 14

x²- 14x -51 = 0
x² - 14x + 49 - 49 - 51 = 0
(x - 7)² = 100
x - 7 = √100
x - 7 = ± 10
Taking RHS positive,
x - 7 = 10
x = 17
Taking RHS negative
x - 7 = -10

x = 7 - 10
x = -3

Thus, the complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.

Answer:

A) -8/5

Step-by-step explanation:

First, convert -8/5 and -5/8 to decimals

-8/5 = -1.6

-5/8 = -0.625

-0.5 is greater than -0.625 because it is closer to 0.

So, the only number less than -0.625 is -8/5, which is equivalent to -1.6

So, the correct answer is A) -8/5

Answer:

4085 milimeters

Answer:

4085 millimeters

Answer:

other root: x = 9

p = 7

Step-by-step explanation:

first, find p:

(8)² - (3p - 4)8 + 11p -5 = 0

64 - (24p - 32) + 11p - 5 = 0 –––––> 64 - 24p + 32 + 11p - 5 = 0

91 - 13p = 0

-13p = -91

p = 7

plug in p to find the polynomial:

x² - (3(7) - 4)x + 11(7) - 5 = 0

x² - (21 - 4)x + 77 - 5 = 0

x² - 17x + 72

find the roots:

we know that 8 is one of the roots, so one factor is (x - 8)

the other number needs to be something that equals -17 when added with -8 and 72 when multiplied by -8

that number is -9

so the poly nomial factors to be: (x-8)(x-9)

so the roots are x = 8 and x = 9

Answer:

p = 7

Step-by-step explanation:

x²-(3p-4)x+11p-5=0    ...(1)    Root: 8, x-8 is factor

(x-8) (x- (11p-5)/8) = 0

x² -8x - ((11p-5)/8)*x + (11p-5) = 0

x² - (8 + (11p-5)/8) x + 11p-5 = 0   ----(2)

compare(1) and (2): 3p-4 = 8 + (11p-5)/8

24p - 32 = 64 + 11p - 5

13p = 91

p = 7

check: x²-(3p-4)x+11p-5 = x²- 17x + 72 = (x-8)(x-9)

Answer:

40 miles

Step-by-step explanation:

Since we are dealing in mph, change the minutes to hr

15 min: 15/60 = .25 hrs

3 min: 3/60 = .05 hrs

:

Let t = his normal drive time to work in hrs

then

40t = the distance to work

Write a distance equation; dist = speed * time

50(t-.25 + .05) = 40t

50(t - .20) = 40t

50t - 10 = 40t

50t - 40t = 10

10t = 10

t = 1 hr normal time to work

therefore

40(1) = 40 mi to work

:

:

Confirm this by finding the dist when he went 50 mph for 48 min (.8hrs)

50(1-.25+.05) = 50(.8) = 40 mi also
