lynne bought a bag of grapefruit, 1 5/8 pounds of apples, and 2 3 /16 pounds of bananas. the total weight of her purchases was 7 1/2 pounds. how much did the bag weight?
Answers
I guess you mean what did the bag of grapefruit weigh, correct?
1 (10/16) lbs apples + 2 (3/16) bananas = 3 (13/16) lbs
Total weight 7 (1/2) pounds = 6 (24/16)
minus 3 (13/16) equals
3 (11/16) lbs the weight of the grapefruit.

A wall of a building is 30 inches wide.sixteen inches is concrete,8 inches is brick,and 6 inches is limestone . What fraction of the wall is concrete.
Answers
The fraction of the wall is concrete is 8/15
What is the fraction?
A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
Given
Wall = 30 inches
Concrete = 16 inches
Brick = 8 inches
Limestone = 6 inches
To determine the fraction of the wall that is concrete
The fraction of concrete is found as follows as
The ratio of the size of concrete to the size of the wall
Substitute 16 for the size of concrete and 30 for the size of the wall
So, Fraction = 16/30
Fraction = 8/15
The fraction can not be further simplified.
Hence, the fraction of the wall is concrete is 8/15

There are 7 bananas, 4 oranges and 5 apples in a fruit basket. Mya selects a piece of fruit at random and Shayla selects a piece of fruit at random. find the probability of picking two apples.
Answers
The probability of picking two apples is 3/4
What is probability
Probability is the likelihood or chance that an event will occur
Probability -= expected outcome/Total outcome
If there are 7 bananas, 4 oranges and 5 apples in a fruit basket, then;
Total outcome = 7 + 4 + 5
Total outcome = 16 fruits
If Mya selects a piece of fruit at random and Shayla selects a piece of fruit at random, the probability of picking 2 apples will be:
Pr(2 apples) = 5/16 * 4/15
Pr(2 apples) = 3/4
Hence the probability of picking two apples is 3/4
Learn more on probability here: brainly.com/question/24756209
(5/16)*(4/15) Mya selects a fruit and you want it to be an apple so that is 5 apples out of 16 fruits total. After Mya selects one fruit and it is an apple, there is one less fruit and apple. So 5-1/16-1. Since the is also in one case, not two separate ones, you multiply the two fractions so (5/16)*(4/15).
In 1626, peter Minuit purchased manhattan island from the Native Americans for $24 worth of trinkets and beads. Find what the $24 would be worth in the year 2014 if it had been deposited in a bank paying 5% interest compounded quarterly. (Round to the nearest dollar)
Answers
Answer:
$24 would be worth $5666315207
Step-by-step explanation:
Given amount invested(principal) = $24
rate of interest = 5% = 0.05
Time period = 2014 - 1626= 388
compounded quarterly so n= 4
Apply compound interest formula
Plug in the values in the formula
A = 5666315206.95264
A = $5666315207
What is the solution set to the inequality 5(x – 2)(x + 4) > 0?
Answers
Answer:
(-∞, -4) U (2,∞)
Step-by-step explanation:
5(x – 2)(x + 4) > 0
First we solve for x, we replace the inequality sign by = sign
5(x – 2)(x + 4) = 0
Divide both sides by 5
(x – 2)(x + 4) = 0
Now we set each factor =0 and solve for x
x-2 =0 , so x= 2
x+4 =0, so x= -4
Now we use number line and make three intervals
First interval -infinity to -4
second interval -4 to 2
third interval 2 to infinity
Now we check each interval with our inequality
First interval -infinity to -4, pick a number in this interval and check with our inequality. lets pick -5
5(-5 – 2)(-5 + 4) > 0
35>0 is true
second interval -4 to 2, pick a number in this interval and check with our inequality. lets pick 0
5(0– 2)(0 + 4) > 0
-40>0 is false
Third interval 2 to infinity, pick a number in this interval and check with our inequality. lets pick 3
5(3 – 2)(3 + 4) > 0
35>0 is true
solution set are the intervals that make the inequalities true

Please hurry! I'll give brainliest for correct answer! If x and y are positive integers, and 3x + 2y = 13, what could be the value of y?
Find one of the two correct answers.
y = ____?
Answers
3x - 2y = 13
3x - (2y/2) = (13/2)
3x - y = 6.5
(3x/3) - y = (6.5/3)
x - y = 2.16
(x-x) - y = (2.16 - x)
-y = 2.16 - x
(-y/-1) = (2.16/-1) -x
y = -2.16 - x
3x + 2y = 13
⇒ 2y = 13 - 3x
⇒ y = 1/2 (13-3x)
We know bot x and y are integers. So
if x = 1, y = 5 ---------------first solution
if x = 2, y = 3.5 -------------not a solution
if x=3, y = 2 ----------------second solution.
Since we need only one answer, y = 2
