Given :

Lulu tells her little brother, Jack, that she is holding 20 coins, all of which are either dimes or quarters.

They have a value of $4.10. She says she will give him the coins if he can tell her how many of each she is holding.

To Find :

How many dimes and quarters in Lulu holding?

Solution :

4.10 dollar = 410 cents

Let, number of dimes and quarter are x and y.

So, x + y = 20 ...1)

Also, 10x + 25y = 410 ...2)

Putting value of 1) in equation 2), we get :

10x + 25( 20 - x ) = 410

10x + 500 - 25x = 410

15x = 90

x = 6

y = 14

Therefore, number of dimes and quarters are 6 and 14 respectively.

Hence, this is the required solution.

Can someone help me ASAP

Answers

I’ll help you with this question.

Step-by-step explanation:

-4.5 x > -21

4.5 = 9/2

WHEN DIVIDING INEQUALITIES WITH NEGATIVE SIGNS, THE GREATHER THAN SIGN WILL CHANGE TO LESS THAN.

-9/2x > - 21

Divide both sides by 9/2 or 4.5

-9/2x / - 9/2 > - 21 / - 9/2

x < 21 × 2/9

x < 7 × 2/3

x < 14/3

x < 4.66666667

Aproximately.... x < 4.7

Answers

Answer:

$5.61

8.5%

Step-by-step explanation:

Cost of meal = $22

Sales tax = $1.87

How much would the sales tax be on $66 meal

= $66/$22 × $1.87

= 3 × $1.87

= $5.61

What is the tax rate for meals in the city

Tax rate = sales tax / cost of meal × 100

= $1.87/$22 × 100

= 0.085 × 100

= 8.5%

Tax rate = 8.5%

What is the slope of the line do the point for me to?

Answers

Answer:

Step-by-step explanation:

we can see that the line goes thru the point (-1,2) and (4,-2) now to find slope we just find change in y over change in x

more visually:

(y1-y2)/(x1-x2)

so for the point (-1,2) let’s say

-1 = x1

and

2 = y1

and for the point (4,-2) let’s say

4 = x2

and

-2 = y2

to find slope we plug in the values to our slope equation and we get this:

(2-(-2))/( -1-4)

(2+2)/-5

4/-5

so slope is -4/5

because to get from (-1,2) to (-4,-2) you have to move down 4 and to the right 5

Select the correct answer. Which statement is true about the extreme value of the given quadratic equation? y = -3x2 + 12x − 33 A. The equation has a maximum value with a y-coordinate of -21. B. The equation has a minimum value with a y-coordinate of -21. C. The equation has a minimum value with a y-coordinate of -27. D. The equation has a maximum value with a y-coordinate of -27.

Answers

Step-by-step explanation:

y = -3x² + 12x - 33

y = -3[x² - 4x + 11]

y = -3[(x - 2)² + 7]

Since the coefficient of x² is negative, the curve concaves downwards and has an absolute maximum value. This happens when x = 2, y = -21.

Therefore the correct option is A.

The ratio of sixth grades to seventh grades in the club of science club is 4:7. If there are 20 sixth grades in the club, how many seventh graders are in the club?

Answers

Answer: 35 seventh graders

Step-by-step explanation:

The simplified ratio is 4:7 sixth graders to seventh graders

The number of sixth-graders is 5 times the number shown in the ratio of attendees (20/4 = 5). Thus, the number of 7th graders must also be 5 times greater than the simplified ratio.

7*5 = 35, thus there are 35 seventh graders in the club

Answer:

Step-by-step explanation:

4 (sixth grader) : 7(seventh grader)

what do we multiply by 4 to get 20? 5

so we have to do the same to the other part of the ratio

soooo

7 x 5 is 35

finally ur answer is 35

What slope would make the lines
parallel?
y = -3x + 9
y = [?]x + 4

Answers

Answer:

- 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 9 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus

y = - 3x + 4 ← is the equation of a parallel line

Answers

Answer:

Step-by-step explanation:

Given

f(x)= x^2-2 and g(x) = 4f (x)-1

g(x) = 4(x^2-2) - 1

g(x) = 4x²-8-1

g(x) = 4x²-9

Get g(-3):

g(-3) = 4(-3)²-9

g(-3 = 4(9) - 9

g(-3) = 36-9

g(-3) = 27

Answer:

Step-by-step explanation:

Given that:

Rental cost = $30

Cost per mile driven = 18 cent

Daily budget = $75

Greatest distance you can drive each day while staying within budget :

Rental cost + (cost per mile driven * distance) ≤ daily budget

$30 + 18d ≤ $75

18d ≤ 75 - 30

18d ≤ 45

d ≤ 45 / 18

d ≤ 2.5

Greatest distance you can drive each day while staying within budget is 2.5 miles.
