Answer:

She is not breaking even. The discounted price is .84t, which is less than t.

Step-by-step explanation:

Retail price= 1.4

1.4×.4= .56

40% of 1.4 is .56

Subtract 40% of 1.4 from the retail price because she is marking down.

(1.4)-(.56)=.84

So the discounted price is .84t

This problem is difficult because we don't know if she sold any tea by the retail price and if she did how much did she sell.

write. (0.25)³ as a multiplication ​

Answers

A number raised to an exponent is the number multiplied by itself the number of times the exponent is.

The exponent is 3, so this means 0.25 is multiplied by itself 3 times.

0.25^3 = 0.25 x 0.25 x 0.25

Answer:0.100

Step-by-step explanation:

If you sed the rule of counting decimal places in the equation to find the number of decimal places in the answer you must not discard zeros too early. For example to multiply 0.25 by 0.4 you need 2+1 decimal places and the multiplication without a decimal point gives 0100. The answer is therefore 0.100.

Stephanie has 20 coins in her purse.
• Some are quarters.
• Some are dimes.
• The total value of the coins is $3.35.
How many of each type of coin does she have?

Answers

Answer:

11 dimes and 9 quarters

Step-by-step explanation:

lets make x quarters and y dimes

Here is the equation we have so far:

x+y=20

BUT it can also be used to determine the values:

0.25x+0.10y=3.35

----------------------------------------------------------------------------

0.25x+0.10y=3.35

x+y=20

Im going to solve for quarters first.

Multiply everything by 0.25 on the bottom equation: 0.25x+0.25y=5

Now you have two equations:

0.25x+0.10y=3.35

and 0.25x+0.25y=5

subtract out the 0.25x

.15y=1.65

y=11

------------------------------------------------------------------------------

you have 11 dimes.

x+11=20

x=9

You have 9 quarters

Answers

Answer:

56-17-43+15

11. ........

Answer: 11

Step-by-step explanation:

We need to start by evaluating the problem, we can simplify this equation so its easier to solve.

So the new equation will be [tex]56-17-43+15[/tex].

56 - 17 = 39

39 - 43 = -4

-4 + 15 = 11.

So [tex]56-17-43+15 = 11[/tex].

11 is the answer.

A circular "No Parking" road sign has a diameter of 26 inches. Which measurement is closest to the area of the sign in square inches? 81.64 in.² 163.28 in.² 530.66 in.² 2,122.64 in.²

Answers

Answer: 81.64

Step-by-step explanation:i took the test

The area of the circle is 530.66 square inches.

What are the properties of the circle?

The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.

Given, A circular "No Parking" road sign has a diameter of 26 inches.

From the general formula of the area of the circle:

Area = π r²

Where r = radius

in our case,

r = diameter/2

r = 26/2

r = 13 inches

Thus,

the area of the circle = pi * 13 * 13

the area of the circle = 530.93 inches²

Therefore, The area of the circle is 530.66 square inches.

Write an inequality to describe the region. The solid upper hemisphere of the sphere of radius 5 centered at the origin

Answers

Answer:

[tex]x^2 + y^2 + z^2 \le 25[/tex] for [tex]z \ge 0[/tex]

Step-by-step explanation:

Given

[tex]r = 5[/tex] --- radius

Required

Determine the inequality of the region

The inequality of a region of a sphere is determined using:

[tex]x^2 + y^2 + z^2 \le r^2[/tex]

Substitute 5 for r

[tex]x^2 + y^2 + z^2 \le 5^2[/tex]

[tex]x^2 + y^2 + z^2 \le 25[/tex]

Solving further: The question says only the upper hemisphere is considered.

This implies that:

[tex]z \ge 0[/tex]

So, the equation is:

[tex]x^2 + y^2 + z^2 \le 25[/tex]

[tex]z \ge 0[/tex]
