Will mark brainliest pls help thx

Answers

Answer 1

If you are considering speed regardless of direction, the average speed is:

(24 + 16) / 2 = 40 / 2 = 20mph

Although if direction matters, then one number has to be negative since the directions are opposite:

(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)

1) What type of slope is shown? *
negative
positive

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

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.

What is the interest on a loan of $2,500 that is borrowed at 9% for 7 months.

Answers

Answer:

$1575

Explanation:

Answer:

$131.25

Step-by-step explanation:

We'll need to review the simple interest formula for this:

I = P(1rt)

This is where P is the principal amount of money to be invested at an interest rate R% (put this in a decimal while calculating). The variable t is the amount of time in years.

Try to plug in these numbers and use my explanation as a checking tool. If you're having trouble, then no worries. Feel free to follow along :D

I = 2,500*(0.09)(7/12)

= 2,500 * 0.525

I = 131.25

So, the interest of a loan of $2,500 underneath those conditions is $131.25

Please let me know in the comments if anything is wrong. I'll be happy to update this answer!

Good luck and keep studying. I believe in you :D

Customers at an ice-cream shop took a survey. The results showed that 279 customers rates the shop as being "very satisfactory." This number represented 45% of the total number of customers who took the survey. What was the total number of customers who took the survey ? Explanation plz

Answers

Answer:

620 customers

Step-by-step explanation:

Customers at an ice-cream shop took a survey.

Let the total number of customers who took the survey be represented by x

We are told in the question that:

The results showed that 279 customers rates the shop as being "very satisfactory." This number represented 45% of the total number of customers who took the survey.

Hence:

45% of x = 279 customers

= 45/100 × x = 279 customers

45x /100 = 279

Cross Multiply

45x = 100 × 279

x = 27900/45

x = 620 customers

The total number of customers who took the survey is 620 customers

d. Richard works for 10 hours and is paid $145. His rate of pay is _____ per hour.
e. 5kg of peas cost $12.58, which equals _____ per kg.

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

Side BC is the longest side
Side AB is the shortest side
Side AC is the longest side
Side BC is the shortest side

Answers

Answer:

AC is the longest side

AB is the shortest

Step-by-step explanation:

Generally, the side that faces the smallest angle has the smallest side while the side that faces the largest angle has the largest side

The measure of the third angle C is 180 - 55 -75 = 50

Kindly note that A faces BC

B faces AC

C faces AB

So while AC is the longest side, AB is the shortest

So the correct answers are;

AC is the longest side

AB is the shortest side
