Mathematics
1 answer:
natali 33 [55]2 years ago
3 0

Answer:

44.7

Step-by-step explanation:

Speed = distance / time

speed from distance a to b = 50 = 10 / time

time = 10/50 = 12 minutes

Speed from a to c = 62 = distance / 30 minutes

distance = 62 x 0.5 = 31 m

diatance from b to c = 31 - 10 = 21

time = 30 - 12 = 28 minutes

speed = 21 / 28 minutes

31 / 0.47

Tara has 3/4 cup of ice cream. How many 1/5 -cup servings are in 3/4 cup of ice cream?
jeka57 [31]
3/4=_/20, to get that multiply the bottom number by each other, in doing so,you will get 15/20, now lets make 1/5= to 20, so we get 4/20 so therefore saying 4/20+4/20+4/20=12/20, so you can make 3 1/5 cups and you will have 3/20 (scoops? cups?) left of ice cream, so 3.75 cups

Evaluate negative 3 to the power of 2 + (2-6)(10)<br><br><br> Please help!
Tom [10]

Answer:

(2-6)(10) plus 3 to the power of 2, is <u>-31</u>.

Explanation:

Three to the power of two plus parenthesis two minus six parenthesis parenthesis ten. This is the same as the sum or addition of 3 times 3(3 times itself two times), and 2 minus 6 times 10.

This expression can be represented by (3^2) + (2-6)(10) which is (3 × 3) + (-4 × 10) which is 9 + -40 which simplifies to -31

The unit price of strawberries at a local fruit stand is $3.29 per pound for quantities of berries indicated in the graph below.
DiKsa [7]

Answer:

Customers who buy more than 7 pounds of strawberries pay $3.29 per pound.

Step-by-step explanation:

Since the graph shows a numerical line from 0 to 12, where the number 7 is shown circled and from there, all the numbers to its right are shaded, it can be said that the graph emphasizes the numbers 8 to 12, understanding So all that range of numbers applies to the offer in question, which applies from the purchase of 8 pounds, that is, more than 7 pounds of strawberries.
