Answers

Answer:

1. C) .4

2. B) 2 1/4

3. D) 3 5/8

Step-by-step explanation:

1. The question is asking what fraction (represented in decimal form) did Maria spend. To find this, divide 18/45 because Maria spent $18 of her $45. When you complete this calculation, you get .4

2. When you look at where the line ends, it's at the first quarter line after the 2, meaning that the line is 2 and one quarter or 2 1/4

3. 8 times 3 is 24, which is the closest multiple of 8 to 29. However, since there is still 5 left over (which still needs to be divided by 8) it would be represented by the mxed fraction.

what is slope intercept form of
slope= -2, y-intercept= -5
slope= -1/4, y-intercept= 1
slope = 2, y-intercept= 0

Answers

Step-by-step explanation:

the slope intercept form of line equation is

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-intercept (the y value when x = 0).

so, we have the equations

y = -2x -5

y = (-1/4)x + 1

y = 2x

Plz help me
I really appreciate it

Answers

Answer:

a = 45°

Step-by-step explanation:

In triangle PSR

PS = RS (Given)

angle SPR = angle SRP (isosceles triangle property)

Let angles SPR and SRP be x

Therefore, 90° + x + x = 180° (angle property)

=> 90° + 2x = 180°

=> 2x = 180° - 90° = 90°

=> 2x = 90°

=> x = 90° ÷ 2 = 45°

=> x = 45°

Hope it helps:)

A textbook store sold a combined total of 236 history and physics textbooks in a week. The number of history textbooks sold was three times the number of physics textbooks sold. How many textbooks of each type were sold

Answers

Answer:

Step-by-step explanation:

Let H and P represent the number of history and physics textbooks.

We are told that:

1) H + P = 236/week, and

2) H = 3P [A disgrace, but that's a different problem]

We can substitute the definition of H in the second equation into the first:

H + P = 236/week

3P + P = 236/week

4P = 236

P = 59

H = 3P, so H = 3*(59) or 177

59 Physics and 177 History books for a total of 236 books sold that week.
