Answer:
A) each donut costs $0.65
B) the price for 1 and 1/2 dozen of donuts (18 donuts) is $11.70
Step-by-step explanation:
For a you have to divide $7.80 by 12 (since its a dozen) and thats how you get $0.65
For b you have to multiply the price of each donut ($0.65) by the 1 and 1/2 dozen (18 donuts) and thats how you get $11.70
Answer:
-8
Step-by-step explanation:
a negative times a positive equals a negative
2 times -4 would be
-4 + -4 which equals -8
.8
All percents are out of 100, so to figure out the answer you must make the denominator, or bottom number in your fraction, 100.
To get to 100, you would multiply 5x20, because that equals 100. Because you multiplied the denominator, which is 5, you must multiply the top number by 20 as well.
4x20 = 80
So therefore, the answer is 80/100, so .8
add the mileage 51+69 = 120 km
add the times 4+5=9 hours
now divide the two
120/9 = 13.3 km per hour average speed
Answer:
a) input 9,10,11
output 12,13,14
Step-by-step explanation:
If we look at the pattern, number 3 is added to the consecutive input numbers 1, 2 and 3 to generate a set of output numbers.
Clearly, option (a) follows this rule. Number 3 is added to the consecutive input numbers 9, 10 and 11 to produce 12, 13 and 14.
In option (b), 4 is added to the input numbers.
In option (c), 2 is added to the input numbers and
in option (d), 3 is multiplied to the input numbers.
Hence, the correct option is (a).
