Answer:

  A) t = 0.25c +25

  B) c = 52

  C) 3 weekday shifts

Step-by-step explanation:

A. The amount Ella earns is $0.25 per cupcake, so for c cupcakes, that is ...

  0.25c

In addition, she is paid $25, so her total amount she is paid is ...

  t = 0.25c +25

__

B. In order to earn $38, the number of cupcakes sold must be ...

  38 = 0.25c +25

  13 = 0.25c . . . . . . subtract 25

  52 = c . . . . . . . . . multiply by 4

Ella sold 52 cupcakes to earn $38.

__

C. On one of the average weekdays, Ella could be expected to earn ...

  t = 0.25(36) +25 = 34

Then for 3 weekday shifts, her earnings would be 3($34) = $102. (It would take Ella 3 weeks to earn $300.)

On one of the average weekend shifts, Ella could be expected to earn ...

  t = 0.25(62) +25 = 40.50

Then for 2 weekend shifts, her earnings would be 2($40.50) = $81. (It would take Ella 4 weekends to earn $300.)

Ella would earn $300 more quickly by working weekday shifts.

Answer:

D

Step-by-step explanation:

If f(x) = 4x ^ 2 - 3 and g(x) = x + 1 , find (f - g)(x)

A. 4x ^ 2 - x - 2

B. x - 4x ^ 2 - 2

C. 4x ^ 3 - 3

D. 4x ^ 2 - x - 4

(f - g)(x) = f(x) - g(x)

4x ^ 2 - 3 - (x + 1 )                  Multiply the brackets by the negative.

4x ^ 2 - 3 -x - 1                       Add like terms.

4x ^ 2 - x - 4                           Final Answer

Answer: [tex]y=2.75x+7.5[/tex], 10 miles

Step-by-step explanation:

Given

The company charges $2.75 per mile

The total charge is $29.50

Also, x represents the number of miles and y represents the total cost of the cab ride

Assume extra charge be c

for 8 miles, the charge is

[tex]\Rightarrow 29.50=2.75\times 8+c\\\Rightarrow c=\$7.5[/tex]

The slope-intercept form of the information is

[tex]\Rightarrow y=2.75x+7.5[/tex]

for $35 charge, miles covered

[tex]\Rightarrow 35=2.75x+7.5\\\Rightarrow 2.75=27.5\\\Rightarrow x=10\ \text{miles}[/tex]

Answer: 47.5 ft

Step-by-step explanation:

since this is a right triangle, you can use trig to solve for x:

cos 22° = [tex]\frac{44}{x}[/tex] (cos = adjacent/hypotenuse)

x * cos 22° = 44

x = [tex]\frac{44}{cos 22}[/tex] (plug into calc)

x = 47.5 ft

Answer:

A) 781.3

Step-by-step explanation:

To find the volume of the cone, you must first find the radius and height of the cone. Which is 7km (radius) and 14km(height).

Next use the formula (Which is in the picture since it's too hard to type out on here)

I also would of explained it but I found it easier just to type it out (In the file attached below)

Finally the answer is 781.3 km

Answer:

  A, E

Step-by-step explanation:

You are correct that the appropriate relationship is ...

  g = 0.4t . . . . choice A

You are also correct that an equivalent relationship is ...

  t = 2.5g . . . . choice D

However, when we say gallons are proportional to seconds, we usually expect that to be written ...

  g = kt . . . . for some value of k

__

We note that another equivalent is ...

  g = 2/5t . . . . choice E

The appropriate choices are probably A and E. Choice D might be argued to be correct, but you could very well lose that argument to someone who prefers a "g = " form of the relationship.

Answer:

y = 19

Step-by-step explanation:

19-9=10

y = 19

No, it cannot equal one because if it did the answer would be -8. If you add 10 and 9 it is equal to 19, which means that y=19.

it's 26 because u count the squares in the poygon

Step-by-step explanation:

If 75% of students come from Kampung Panda, then 25% come from Kampung Melayu (100 - 75 = 25).

Take 25% of 800 students to get 200 students coming from Kampung Melayu.

[tex]0.25 * 800 = 200[/tex]

or

[tex]\frac{1}{4} * 800[/tex]

[tex]\frac{800}{4}[/tex]

Step-by-step explanation:

Fixed Cost = $25 membership fee

Variable Cost = $0.25 per hour of play

Given n is the number of hours played and D is the total cost,

D = Fixed cost + variable cost($0.25 x n hours)

Answer:

The common denominator would be 40

Step-by-step explanation:

Answer:

Since the calculated value of z= 2.82  does not lie in the critical region  the null hypothesis is accepted and it is concluded that the sample data support the authors' conclusion that the proportion of the country's boys who listen to music at high volume is greater than this proportion for the country's girls.

The value of p is 0 .00233. The result is significant at p < 0.10.

Step-by-step explanation:

1) Let the null and alternate hypothesis be

H0:  μboys − μgirls > 0

against the claim

Ha: μboys − μgirls ≤ 0

2) The significance level is set at 0.01

3) The critical region is z  ≤  ± 1.28

4) The test statistic

Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]

Here p1= 397/768= 0.5169  and p2= 331/745=0.4429

pc = 397+331/768+745

pc= 0.4811

qc= 1-pc= 1-0.4811=0.5188

5) Calculations

Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]

z= 0.5169-0.4429/√ 0.4811*0.5188( 1/768+  1/745)

z= 2.82

6) Conclusion

Since the calculated value of z= 2.82  does not lie in the critical region  the null hypothesis is accepted and it is concluded that the sample data support the authors' conclusion that the proportion of the country's boys who listen to music at high volume is greater than this proportion for the country's girls.

7)

The value of p is 0 .00233. The result is significant at p < 0.10.

pyramid A: 16 + [tex]8\sqrt{5[/tex]

pyramid B: 400 + [tex]8\sqrt{125[/tex]

pyramid A: 4 by 4= 16 cm.

with a height of 1 and length of 2, we use pythagorean theorem to find height of other surfaces to be square root of 5. area of triangle is 1/2 bh

square root of 5 multiplied by 4 and divided by 2 is 2 root 5

multiply this by 4 sides total for 8 root 5

Add the 8 root 5 to 16

To find pyramid B: use ratio of 25:1 and multiply 16 by 25 to find 400, and root 5 to 125

Answer:

$4298.10

Step-by-step explanation:

Using the relation :

V = Pe^rt

P = 3090 ; r = 3% = 0.03 ; t = 11 years

V = 3090 * e^(0.03 * 11)

V = 3090 * e^0.33

V = 3090 * 1.3909681

V = 4298.0915

Amount in the investment after 11 years will be $4298.10

Answer:

Hello! The interest would be $184. You would have to use the formula

I= P x r x t. I would equal interest, p is principal amount, r is interest rate and t is the time involved which is 5 years. But first you have to divide 8% by 100 which is 0.08. 460 x 0.08 x 5= $184
