A store sells the following brands of pasta sauce. Brand A: 32 oz. for $2.90 Brand B: 20 oz. for $2.09 Brand C: 48 oz. for $4.00 Brand D: 10 oz. for $1.25 Which brand is the best buy?

Answers

I think brand A (32oz for 2.90$)

Brand A: 32 oz. for $2.90

Brand B: 20 oz. for $2.09

Brand C: 48 oz. for $4.00

Brand D: 10 oz. for $1.25

-----

To solve you will have to divide cost/oz.

-----

Brand A: 1 oz. for $0.09

Brand B: 1 oz. for $0.10

Brand C: 1 oz. for $0.08

Brand D: 1 oz. for $0.13

-----

So, Brand C is the best buy because it is the cheapest.

A. 41 ft 3 in
B. 42 ft 4 in
C. 41 ft 2 in
D. 40 ft 6 in

Answers

Answer:

41 ft 2 in

Step-by-step explanation:

Since the two triangles in question, that means that the triangles have the same proportions. We know that GH = 16 ft 7 in = 199 in (16x12+7) and HN = 6 ft 3 in = 75 in (6x12+3). GH/HN is 199/75. This is the same ratio that GO/AN will have as well. GO is unknown so we will denote it as x and AN = 15 ft 6 in = 186 in (15x12+6). We know that these two fractions are equal. 199/75 = x/186 solving for x, we get x = 493.52 in and converting that into feet we get 41 ft 1.52 in which rounds to 41 ft 2 in.

If we divide both the top and the bottom by 5 since we know that 125 is a multiple of 5, we get 25/200. Divide both by 5 again to get 5/40 we then simplify to get 1/8.

Lin runs 5 laps a track in six minutes how many minutes per lap is that

Answers

Answer:

1.2 minutes

Step-by-step explanation:

6 divided by 5 = 1.2

To do this, you take the total number of minutes, which is 6, and divide by the number of laps that Lin ran, which was 5.

Answer:

1.2 minutes

Step-by-step explanation:

5 laps/6 minutes = 1 lap/x minutes

To convert the ratio from 5 laps to one laps, 5 was divided by 5. Therefore, to keep the same ratio, 6 must also be divided by 5, making the answer:

1 lap/1.2 minutes

Mario plays basketball on a town league team. The
table below gives Mario's scoring statistics for last
season. How many points did Mario score playing
basketball last season?

Answers

Answer:

Step-by-step explanation:

Total points Mario scored = total 1-point free throw + total 2-point field goal + total 3-point field goal.

In 80 attempts 1-point free throw, Mario had 75% success rate. That is, Mario had 80 x 75/100 success

80 x 75/100 = 60

Thus, Mario scored 1 x 60 (since for each success, 1 points is added) points = 60

In 60 attempts 2-point field goal, Mario had 90% success rate. That is, Mario had 60 x 90/100 success

60 x 90/100 = 54

Thus, Mario scored 2 x 54 points (since for each success, 2 points are added) = 108

In 60 attempts 3-point field goal, Mario had 25% success rate. That is, Mario had 60 x 25/100 success

60 x 25/100 = 15

Thus, Mario scored 3 x 15 points (since for each success, 3 points are added) = 45

Therefore, the total points Mario scored = 60 + 108 + 45

= 213

Answer:

Rhombus and angle 1 = 35

Step-by-step explanation:

The parallelogram has the same marking on each of its sides, indicating that all the sides are equal in length. It is, therefore, a rhombus.

It is given that one of the angles measures 110 degrees. The other angle is 70 degrees (because 180 - 110 = 70). Since it is bisected by a line, divide the angle by 2 (70/2). You get 35 degrees. Therefore, the measure of angle 1 is 35 degrees.

C

D

Answers

The answer is c I hope this helps

The family needs to cover 39ft² area of grass.

What is Area of Circle?

The area of a circle is the amount of space enclosed within the boundary of a circle. The region within the boundary of the circle is the area occupied by the circle.

Here, Diameter = 7 ft.

          Radius = 7/2 ft. = 3.5 ft.

The Area of Circle = πr²

              A = 3.14 X (3.5)²

              A = 3.14 X 3.5 X 3.5

             A = 38.465 ft² ≈ 39 ft²

Thus, the family needs to cover 39ft² area of grass.

First she found three points on the graph to be (1, 4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (1, 4) and (0, -3) to be StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction = StartFraction 1 Over 1 EndFraction = 1. and the rate of change between the points (0, -3) and (2, 5) to be StartFraction 5 minus (negative 3) Over 2 minus 0 EndFraction = StartFraction 8 Over 2 EndFraction = 4.
