Answer: The weight of mail at noon is 104 pounds.

Step-by-step explanation:

Given that , At a post office, the weight of the mail at 10.00 A.M was 80 pounds.

Two hours later, the weight of the mail had increased by 30%.

Since , time after 2 hours of 10 A.M would be 12 P.M which is known as noon.

Mathematically , the weight of the mail at noon = (Weight at 10 AM) +30% of (Weight at 10 AM)

= 80 + 0.30(80) pounds

= 80 (1+0.30) pounds

= 80 (1.30) pounds

= 104 pounds

Hence, the weight of mail at noon is 104 pounds.

Find the product: (30 gallons 3 quarts 1 pint) × 5
maks197457 [2]

Answer:

Please mark me brainliest!!!!!!!

Step-by-step explanation:

Step 1:

Multiply each by 5, then make any necessary conversions to the other units of measurement (ie. gallon, quart, etc)

30 gallons x 5= 150 gallons

3 quarts x 5= 15 quarts

1 pint x 5= 5 pints

Step 2:

CONVERSION

1 gallon=4 quarts

1 gallon= 8 pints

1 quart= 2 pints

GALLONS: 150 gallons

QUARTS:

=15 quarts ÷ # quarts in gallon

=15/4= 3 gallons 3 quarts

PINTS:

=5 pints ÷ # pints in quart

=5/2= 2 quarts 1 pints

TOTALS:

150 gallons

3 gallons 3 quarts

2 quarts 1 pint

Since we have 5 additional quarts, and we know that 4 quarts=1 gallon, we need to convert again.

=3 quarts + 2 quarts

=5 quarts ÷ # quarts in gallon

=5/4 = 1 gallon 1 quart

FINAL TOTALS

GALLONS: 150 + 3 + 1= 154 gallons

QUARTS: 1 quart

PINTS: 1 pints

Simplify 5 to the negative 4th power over 5 to the 3rd. Group of answer choices 57 5−1 1 over 5 1 over 5 to the 7th power
STatiana [176]
When you divide exponents, you have to subtract them. So -4-3= -7 as the exponent

When you have a negative exponent, then you have to flip the fraction (all whole numbers are over 1 so flip the 1 to the top and the 5^7 on the bottom)

Hitman42 [59]

Answer:

Here, b represents buying fins and leashes.

As per the statement:

Vincent is ordering accessories for his surfboard. A set of fins cost $24 each and a leash costs $15.

A set of fins cost $24 each and a leash costs $15

It is also given that: The shipping cost is $4 per order.

then;

Cost in dollars of buying b fins and b leashes plus the cost of shipping

= 24b+15b+4

Therefore, the expression  24b+15b+4 represents the cost in dollars of buying b fins and b leashes plus the cost of shipping.
