The length of the hypotenuse, line segment AC, in right
triangle ABC is 25 cm. The length of line segment BC is
15 cm.

Answers

What is the question? The Hypotenuse? If so there is still not enough evidence.

if the question is asking for the length of AB :
since the triangle is a right angled one, we can apply the Pythagoras’ Theorem.

AC^2 = BC^2 + AB^2
25^2 = 15^2 + AB^2
625 = 225 + AB^2
AB^2 = 400
AB = 20cm

The length of line AB is 20cm.

1) What type of slope is shown? *

Answers

The slope is positive. Hope this helps :)

Answer:

hi! so the way I do this is I hold my hand out and do a ninja chop! I know this is weird but it's helpful or you could remember right and left!

anyways your line is "chopping" or leaning right which means you use your right hand not your left to recreate this line right is positive!

so this would be positive if it was negative it would go to the left and if you're using your hand to "chop" like a knife then you would use your left hand because your line would lean to the left

not sure if the chop method works for everyone but you could always remember right is positve and left is negative

update: found this weird picture but this is basically what I mean when I say chop LOL

Answers

Answer:

a. 64

b. 7.5

c. 7 min 5 sec

d. 14.5

e. 2.52

The rate per hour is 64 km / hr. The rate per book is $7.50. The rate per minute is 5 litres. The rate pay per hour is $14.50. The weight per kg is 2.52 kg.

The rate per hour is known as the average speed.

Average speed = total distance / time

320 / 5 = 64 km / hr

The rate per book is the cost of one book.

Cost of one book = total cost of the book / number of books bought

$360 / 48 = $7.50

The rate per minute = total litres / total minutes

900 / (2 x 60)

900 / 180 = 5 litres per minute

Rate pay per hour = total amount earned / total hours worked

$145 / 10 = $14.50 per hour

Cost per kg = total cost of the peas / total weight of the peas

$12.58 / 5 = $2.52 per kg

When Susan babysat for 8 hours and did odd jobs for 3 hours, she made a total of $39. When she babysat for 2 hours and did odd jobs for 5 hours, she made a total of $31. How much does she charge per hour for babysitting and for doing odd jobs?

Answers

Answer:

x = charge for babysitting = $3

y = charge for doing odd jobs = $5

Step-by-step explanation:

Let

x = charge for babysitting

y = charge for doing odd jobs

8x + 3y = 39 (1)

2x + 5y = 31 (2)

Multiply (1) by 5and (2) by 3

40x + 15y = 195 (3)

6x + 15y = 93 (4)

Subtract (4) from (3)

40x - 6x = 195 - 93

34x = 102

Divide both sides by 34

x = 102 / 34

= 3

x = $3

Substitute x = 3 into (1)

8x + 3y = 39

8(3) + 3y = 39

24 + 3y = 39

3y = 39 - 24

3y = 15

y = 15 / 3

= 5

y = $5

x = charge for babysitting = $3

y = charge for doing odd jobs = $5
