Answer:

She bought

22 of the 52 cent stamps and

26 of the 23 cent stamps.

Step-by-step explanation:

Given :

Total stamp increase = 48

Let number of 52 cent stamp = x

Number of 23 cent stamp = 48 - x

The cost equation :

0.52*x + 0.23*(48-x) = 17.42

0.52x + 11.04 - 0.23x = 17.42

0.52x - 0.23x = 17.42 - 11.04

0.29x = 6.38

x = 6.38 / 0.29

x = 22

Hence,

She bought 22 ; 52-cent stamps

And (48 - 22) = 26, 23-cent stamps

Answer:

D

Step-by-step explanation:

But basically, one by one you try moving the terms out of the radical.

75 is also 25 * 3 and since 25 has a perfect square root of 5 that goes out and 3 stays inside the radical.

x^3 is also x^2 * x and since x^2 has a perfect square root which is just x that goes outside while the remaining x stays inside.

y^9 is also y^8 * y and since we move variables out the radical in twos y^ goes outside the radical and y stays inside alone.

Finally, z is just z it can't be taken out so it stays inside the radical.

Hope that helps!

Answer:

17,576,000 different license plates are possible.

Step-by-step explanation:

Fundamental counting principle:

States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.

In this question:

For each letter, there are 26 possible outcomes.

For each digit, 10 possible outcomes.

So

L - L - L - D - D - D

Number of possible outcomes:

26 - 26 - 26 - 10 - 10 - 10

Each character of the license plate is independent, so, by the fundamental counting principle:

26*26*26*10*10*10 = 17,576,000

17,576,000 different license plates are possible.

Answer:

D. 50 yd³

Step-by-step explanation:

Volume of triangular pyramid = ⅓ * Base Area * height of pyramid

Base area = ½*b*h = ½*6*5

Base area = 15 yd²

height of pyramid = 10 yd

Volume of the triangular pyramid = ⅓*15*10

Volume of the triangular pyramid = 5*10

= 50 yd³

Answer: The equation has 2 positive integer solutions:

x1 = 0   y1 = 2  

x2 = 1   y2 = 0  

Step-by-step explanation:

The value of x = -4.334  and y = 10.667.

When written as ax + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e., a and b, respectively, are not zero, an equation is said to be a linear equation in two variables.

For this kind of equation, the solution is a pair of values, one for x and one for y, which also make the two sides equal.

Given Equations 12x + 6y = 12...….(1)

    y  = x + 15

y - x = 15...….(2)

divide eq. (1) by 6

(12x + 6y)/6 = 12/6

2x + y = 2

subtract from eq. (2)

y - x  - (2x + y)  = 15 - 2

-3x = 13

x = -13/3 = -4.334

substitute value of x in eq. (2)

y - (-4.334) = 15

y = 15 - 4.334

y = 10.667

Hence the solution of equations gives x = -4.334 and y = 10.667.

Answer:

12

Step-by-step explanation:

The formula to find the area of a triangle is the following,

[tex]A=\frac{b*h}{2}[/tex]

Where (b) and (h) are the base and height of the triangle. In this situation, one can see that the base (CB) equals (8) units. One can attain this number by counting the boxes between point (C) and point (B). The height is (3). This number is the distance from the point (A) to the side (CB). Substitute these values into the formula and solve for the area.

[tex]A=\frac{b*h}{2}[/tex]

Substitute,

[tex]A=\frac{8*3}{2}[/tex]

Simplify,

[tex]A=\frac{8*3}{2}\\\\A=\frac{24}{2}\\\\A=12[/tex]
