Maggie has twice as many apples in her grocery bag as her friends Leilani and Adeline combined. Leilani has 5 apples in her bag. Maggie has 20 apples in her bag. How many apples does Adeline have in her grocery bag? there's Abcd for the question
Answer:
5

If Leilani has 5 apples, that means that Maggie has 10, but Maggie has 20 so that means that Adeline has 5 apples, because 5+5 is 10 and 10 doubled is 20
The scale on a map is 1 cm for every 400 km. If Maine and Japan are 26 cm apart on the map, what is the distance between Maine and Japan?
Answer:
10400km
Step-by-step explanation:
We know that the scale on a map is 1cm for every 400km. So to find the actual distance for 26cm on the map, we take 26 multiplied by 400km. This gives 10400km.

10ft 10ft 16ft height is 8 ft what's the area of a triangle
Answer:
The area is 64ft ^2.
Step-by-step explanation:
I believe this is an isosceles triangle and if so our base will be 16ft and our height will be 8ft, knowing this we can solve for the area.
Use the form A=bh/2
Now plug it in...
A=16x8/2
A=128/2
A=64ft ^2

If there are 18 boys and 22 girls in a class. One student was absent on one day. What is the probability of the absentee being a girl?
Answer:
22/40 or 11/20 or 55%
Step-by-step explanation:
First, we have to find the total number of students.
18+22=40
The percentage of girls in the class is 22/40.
That's also the probability of the absentee being a girl.
A rabbit and a turtle run 100 meters. When the rabbit finished, the turtle was behind by 80 meters. Next time they want to finish together. The turtle still runs 100 meters. How many meters behind the turtle should the rabbit start? (Assume that they run at a constant rate during the competition.) ITS NOT 80
From the fraction solved, the distance that the rabbit should be behind the turtle will be 400 meters.
How to solve the distanceFrom the information, it was stated that a rabbit and a turtle run 100 meters and that when the rabbit finished, the turtle was behind by 80 meters. Therefore, the distance covered by the turtle will be:
= 100 - 80
= 20 meters
Therefore, the fraction of their distance will be:
= 20/100 = 1/5
Therefore, the number of meters behind the turtle that the rabbit should start will be:
= 80 × 5
= 400 meters.

Diego said that these graphs are ordered from smallest to largest. Mai said they are ordered from largest to smallest. But these are graphs, not numbers! what do you think diego and mai are thinking?.
Both Diego and Mai are interpreting the said graphs (please see attached) in terms of which are Negative, Positive, or neutral.
The Interpretation of the GraphsWhen you want to interpret a linear equation in relation to a graph, it is important to note that two factors are critical:
If the slope of the line rises from left to right, it is Positive; If it falls from left to right, it is negative, and if it remains on the same line across, but above the y-axis, then it is constant but above zero.
Therefore, in the order they have been arranged, the first graph is negative because its last value falls below the y axis, the second is above the y-axis but constant at a level above zero, while the third has its values increasing from left to right above the y-axis.

The equation is

Given :there are 2 rows of given length with 5 chairs left over.6 rows of the same length if given 11 more chairsAssumption :Let, no. of chairs in each row = x
Explanation :There are 2 rows of given length with 5 chairs left over.
6 rows of the same length if given 11 more chairs 2x+5 will be equal to 6x
If 11 chairs are added to 2x+5 because 6x has 11 more chairs than 2x+5
=> 2x+5+11 = 6x
=> 2x+16 = 6x
=> 4x = 16
=> x = 16/4
=> x = 4
Answer :x=4 chairs in each row with 5 left over makes 2*4+5 = 13 chairs
add 11 chairs to 13 chairs and you get 24 chairs which is 6 rows of 4 chairs in each row.

PLS HELP ME!!?!?!?!? Ok so Steve had a $6.00 coupon to the school store. Steve used his coupor Each notebook cost the same amount. After using the coupon, he still owed $5.25, not including tax. How much did one notebook cost
Answer:
Each notebook costs $1.25
Step-by-step explanation:
We'd have to add back the $6.00 coupon to the original price which would now be $11.25.
After getting the original price we now have to divide the price by 9, because of the 9 notebooks you've purchased.
Therefore, the price of $11.25 divided by the 9 notebooks would cost 1.25 each.

the total amount of money that the school
collects for lunches over the course of a 180-

at a rate of 3.75% each year.
When will the population reach 1,000,000 (to the nearest year)?
Answer:
6097
Step-by-step explanation:
6,250 + 3.75% =
