A store plans to mark down all dresses by 60%. Julie wants to purchase a dress that is currently priced at $75. What amount of money will Julie save if she buys the dress after the store marks it down?

Answers

Answer 1

0.6 × 75$ = 45$ saved

Answer 2

Answer:45

Step-by-step explanation:For Julie's situation, the percent equation becomes:

money saved = percent of markdown × current price

Since the markdown is 60% off $75,

money saved====percent of markdown × current price60%×$750.6×7545

So, Julie will save $45.

What is the area under the normal curve between z = 0.0 and z = 1.79?

Answers

0.4633.

I remember some of the questions to this assignments.

Final answer:

The area under the normal curve between z = 0.0 and z = 1.79 is 0.4641.

Explanation:

The area under the normal curve between z = 0.0 and z = 1.79 can be found by subtracting the area to the left of z = 0.0 from the area to the left of z = 1.79.

The area to the left of z = 0.0 is 0.5000, and the area to the left of z = 1.79 is 0.9641 according to the Z-table.

Subtracting the two values, we get an area of 0.4641 between z = 0.0 and z = 1.79.

Can 3.65909090909 be expressed as a fraction whose denominator is a power of 10? Explain.

Answers

[tex]\bf 3.659\textit{ can also be written as }\cfrac{3659}{1000}\textit{ therefore }3.6590909\overline{09}\\\\ \textit{can be written as }\cfrac{3659.0909\overline{09}}{1000}[/tex]

notice above, all we did, was isolate the "recurring part" to the right of the decimal point, so the repeating 09, ended up on the right of it.

now, let's say, "x" is a variable whose value is the recurring part, therefore then

[tex]\bf \cfrac{3659.0909\overline{09}}{1000}\qquad \boxed{x=0.0909\overline{09}} \qquad \cfrac{3659+0.0909\overline{09}}{1000}\implies \cfrac{3659+x}{1000}[/tex]

now, the idea behind the recurring part is that, we then, once we have it all to the right of the dot, we multiply it by some power of 10, so that it moves it "once" to the left of it, well, the recurring part is 09, is two digits, so let's multiply it by 100 then,

[tex]\bf \begin{array}{llllllll} 100x&=&09.0909\overline{09}\\ &&9+0.0909\overline{09}\\ &&9+x \end{array}\quad \implies 100x=9+x\implies 99x=9 \\\\\\ x=\cfrac{9}{99}\implies \boxed{x=\cfrac{1}{11}}\\\\ -------------------------------\\\\ \cfrac{3659.0909\overline{09}}{1000}\qquad \boxed{x=0.0909\overline{09}} \quad \cfrac{3659+0.0909\overline{09}}{1000}\implies \cfrac{3659+x}{1000} \\\\\\ \cfrac{3659+\frac{1}{11}}{1000}[/tex]

and you can check that in your calculator.

Write each equation in slope intercept form 5x+3y=30

Answers

Get rid of x first -5x then divide the rest

Slope intercept form is: y = mx + b.

In order to get x to the other side, you subtract it on both sides.
3y = -5x + 30

But in slope intercept form, y can’t have any number in front of it. To get rid of the number, divide both sides by 3

y = -5x/3 + 6

So what this is, is the range from 0 - 4, not including 4, or the range from 5 - 9, not including 9.

Obviously the mean and median aren't shown.

So in this case it would be the first one, since the second bar isn't including 9, so it wouldn't include 9, so we wouldn't know how many of 10-14 are 9s, so we don't know that.

A class of 40 students elected a class president. There were 12 votes for Candidate A, and 18 votes for Candidate B. The remaining students in the class did not vote. Which expression gives the percent of voters who voted for Candidate A?

Answers

Hey You!

12/40 = Candidate A.

18/40 = Candidate B.

12 + 18 = 30

40 - 30 = 10

10/40 = Those who didn't vote.

ANSWER:

12 ÷ 40 = .3 (30%) So 30% voted for Candidate A.

18 ÷ 40 = .45 (45%) So 45% voted for Candidate B.

10 ÷ 40 = .25 (25%) So 25% didn't vote at all.

Suppose θ is an angle in the fourth quadrant with cosθ=x/4. Find expressions for the other five trig functions in terms of x?

now, for the cotangent and the cosecant, let's rationalize the denominator,

[tex]\bf cot(\theta)=\cfrac{x}{-\sqrt{16-x^2}}\cdot \cfrac{\sqrt{16-x^2}}{\sqrt{16-x^2}}\implies cot(\theta)=-\cfrac{x\sqrt{16-x^2}}{16-x^2} \\\\\\ csc(\theta)=\cfrac{4}{-\sqrt{16-x^2}}\cdot \cfrac{\sqrt{16-x^2}}{\sqrt{16-x^2}}\implies csc(\theta)=-\cfrac{4\sqrt{16-x^2}}{16-x^2}[/tex]

boa saved $179 a month. he saved $145 less than ada each month. how much would ada save in three and a half years?

Answers

B saves 179 a month, A saves 145 more which is equal to 324
three and a half years is 42 months
42 months times 324
13608

First we need to see how much money Ada gets each month, since the question is in regards to her money, not Boa's.

It says Boa's savings each month are "$145 less than Ada", so we need to add 179 to 145. 179+145 = 324.

Okay, so now we know the amount of Ada's savings per month, we need to find out how much money she would have in 3 and a half years. 12 months is equal to one year. A half a year is 6 months. Three whole years is 36 months, and 6 months added to that is 42 months.

Since $324 represents only one month, and we want 42 months, we need to multiply 324 by 42. 324*42 = $13608. $13608 is what Ada saved within 3 years and a half.

What is the molar solubility of magnesium fluoride in a solution that is 0.40 m f− ions? the ksp of mgf2 is 6.4 × 10−9. hints what is the molar solubility of magnesium fluoride in a solution that is ions? the of is . 8.0 × 10−9 8.0 × 10−5 1.6 × 10−8 4.0 × 10−8?

Answers

Answer: MgF2 ====â‡’ Mg+2 + 2F- Ksp = [Mg+2][F-]^2 Let S = molar solubility of MgF2 [Mg+2] = S ; [F-] = 2s Since the [F-] is initially 0.40 M, then [F-] = 0.40 + 2S 6.4 x 10^-9 = (S) (0.40 + 2S)^2 ; one can neglect the 2S in the 0.40 + 2S expression since it is very, very small compared to the 0.40 already present. 6.4 x 10^-9 = S(0.40)^2 S = 4.0 x 10^-8 Molar solubility = 4.0 x 10^-8

Final answer:

The molar solubility of magnesium fluoride in a solution with a concentration of 0.40 M fluoride ions is 0.80 M.

Explanation:

The molar solubility of magnesium fluoride in a solution with a concentration of 0.40 M fluoride ions can be calculated using the solubility product constant (Ksp) of MgF2, which is 6.4 × 10-9.

First, write the dissolution equation for MgF2: MgF2(s) ⇌ Mg2+(aq) + 2F-(aq)

Since the stoichiometry of the dissolution equation is 1:2 between magnesium ions and fluoride ions, the molar solubility of MgF2 is twice the concentration of fluoride ions.

Therefore, the molar solubility of MgF2 in a solution that is 0.40 M fluoride ions is 2 × 0.40 M = 0.80 M.

A hair salon charges fixed rate of $25.00 for a haircut and then an additional $15.00 for any other services. Write a function to model cost of services there and then determine how many services you had if you were charged for $115.00

Answers

Fixed Cost: $25 Additional Cost: $15 per service To demonstrate how much a customer would have to pay for a trip to the salon, one can use the equation Total Cost = Fixed Cost + (Additional Cost x Number of services), or Total Cost = 25 + (15 x Number of services). If I were charged for $115, I would use the equation 115 = 25+(15xServices), and solve this to find that the number of services received was six.

Answer:

f(x) = 15x + 25; f(6) = 115

Step-by-step explanation:

the flat rate of $25 will be the y-intercept and the slope will be $15. since u are charged $115, plug that in for f(x) and solve for x. so the right answer is

f(x) = 15x + 25; f(6) = 115

Each package of dried fruit contains 3/16 of a pound Mr. Lopez has 4 pounds of dried fruit How many packages can he fill

Answers

Final answer:

Mr. Lopez can fill 21 full packages of dried fruit, each containing 3/16 of a pound, with his 4 pounds of dried fruit.

Explanation:

The question asks how many packages of dried fruit Mr. Lopez can fill if each package contains 3/16 of a pound and he has 4 pounds of dried fruit. To answer this, we need to perform a division to find out how many 3/16 are in 4 pounds.

To solve this, we divide 4 pounds by 3/16 pounds per package:

4 ÷ (3/16) = (4/1) ÷ (3/16) = (4 × 16) / 3 = 64/3 = 21 with remainder 1.

Therefore, Mr. Lopez can fill 21 full packages of dried fruit and will have a little left over which is not enough to fill an additional full package.
