Answers

Answer:

The answer is D.

Step-by-step explanation:

The answer is D because the total number of people who chose flight was 37. Researchers said they surveyed, 100 people in total so 37 out of those 100 people choose flight, hence the answer being D.

Answer:

37/100

Step By Step:

Take the total of students who chose flight and put it over the total number of students, in this case, 37/100.

Directions: Drag each tile to the correct box.Order the following conditions in order from the largest number of possible triangles to the least number of possible triangles.

Condition A: a perimeter of 12 and even-numbered side lengths
Condition B: a side length of 4 inches, a side length of 5 inches, an included angle of 110º, and a perimeter of 11 inches
Condition C: a right triangle with an area less than 13 square inches and odd-numbered leg lengths greater than 1 inch
Condition D: an isosceles triangle with two angles that measure 50º

Answers

D, C, A nad then B
Figure out the number of possible triangles that fit condition A. There are 3 possible combinations of three even numbers that sum to 12.Of these three, there is only one where every length is less than the sum of the other two: 4 inches,4 inches, 4 inches. So, there is only one triangle that fits condition A.Figure out the number of possible triangles that fit condition B. Since the perimeter and two side lengths are given, subtract the two side lengths from the perimeter to get the length of the third side.Sketch a triangle with lengths of 2 inches, 4 inches, and 5 inches.From the sketch, the angle between the 4-inch length and 5-inch length has to be the smallest angle. Since it has to be the smallest angle, it cannot be more than a right angle. So, there is zero triangles that fit condition B.Figure out the number of possible triangles that fit condition C. For the area to be less than13 square inches, the product of the legs must be less than 26 square inches. The right triangles with odd-numbered legs greater than 1 inch whose product is less than 26 square inches are shown below.So, three triangles fit condition C.Figure out the number of possible triangles that fit condition D. If two angles of an isosceles triangle measure 50º, the third can be found by subtraction both angle measures from 180º.So, the angle measures must be 50º, 50º, and 80º. There is no condition on the lengths, so there are an infinite number of triangles that fit condition D.Therefore, the conditions in order of greatest possible triangles to least are shown below.condition D, condition C, condition A, condition B

Lynne bought a bag of grapefruit, 1 and 5/8 pounds of apples, and 2 and 3/16 pounds of bananas. The total weight of her purchases was 7 and 1/2 pounds. How much did the bag of grapefruit weigh?

Answers

The answer would be 3 and 11/16.
First add the 1 and 5/8 to 2 and 3/16.
Subtract this sum from the total 7 1/2 pounds. This will give the weight of grapefruit.
Let, the weight of Grapefruit = x
It would be: x + 1 5/8 + 2 3/16 = 7 1/2
x + 13/8 + 35/16 = 15/2
16x+26+35 /16 = 15/2
16x+61/16 = 15/2
2(16x+61) = 15*16
32x + 122 = 240
x = 118/32
x = 3.68 
x = 3 11/18 Pound

In short, Your Answer would be 3 11/18 Pound

Two integers, a and b have product of -48 what is the greatest possible sum of a and b.

Answers

The factors of 48 are:
1 x 48
2 x 24
3 x 16
4 x 12
6 x 8
and visa versa:   48 x 1  etc.

To make the product negative, one of the factors has to be positive and one has to be negative.  To find the greatest sum, make the bigger number the positive factor and the smaller number the negative factor.  So, -1 x 48 = -48 and the sum of -1 + 48 = 47 which would be the greatest possible sum.
