Grant bought strawberries and bananas from the grocery store to make smoothies. The total amount he spent can be represented by the expression 1.8s + 0.65b, where s is the number of pounds of strawberries and b is the number of pounds bananas. If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas, how much did he spend? Amount spent can be represented by the exper

Answers

Answer:

$5.77

Step-by-step explanation:

Given expression:

1.8s + 0.65b

where,

s = the number of pounds of strawberries

b = the number of pounds bananas

If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas

s = 2.7 pounds

b = 1.4 pounds

how much did he spend?

1.8s + 0.65b

= 1.8(2.7) + 0.65(1.4)

= 4.86 + 0.91

= $5.77

He spent $5.77 on both items

Answers

Answer:  [tex]\dfrac{1}{10}[/tex]

Step-by-step explanation:

Given: The bag has 5 green chips, 3 red chips, and 7 blue chips.

Total chips = 5+3+7= 15

Number of ways to select a red and then a blue chip = 3 x 7 = 21

Total number of ways to select 2 chips without replacement = 15 x 14 =210

Required probability = [tex]\dfrac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex]

[tex]=\dfrac{21}{210}=\dfrac{1}{10}[/tex]

So, the probability that he selects a red and then a blue chip (without replacing) =  [tex]\dfrac{1}{10}[/tex]

Bill averages 10 points a game and has 110 points for the season. Aaron averages 12 points a game and has 96 points for the season. Solve an equation to find how many games it will take until they tie in points scored if they continue at the same rate.

Answers

Answer:

ok yes

Step-by-step explanation:

The number of games it will take until they tie in points scored if they continue at the same rate is;

7 games.

We are told that Bill averages 10 points a game and has 110 points for the season.

Thus, number of games a season it will take bill to reach 110 points is; 110/10 = 11 games

Aaron averages 12 points per game and has 96 points for the season. Thus, number of games a season it will take bill to reach 96 points is;

96/12 = 8 games.

Now, let the additional number of games to be played for them to have the same points be x. Thus;

110 + 10x = 96 + 12x

12x - 10x = 110 - 96

2x = 14

x = 14/2

x = 7

In conclusion, the additional number of games it will take for Bill and Aaron to have the same number of points is 7 games.

A high school track​ team's long jump record is 24 ft 9 1/4 in. This​ year, Arthur​'s best long jump is 24 ft 3 1/2 If long jumps are measured to the nearest quarter​ inch, how much farther must jump to break the​ record?

Answers

Answer:

5 3/4 inches

Step-by-step explanation:

Given that :

Long jump record held = 24 ft 9 1/4 in

Arthur's best long jump record = 24 ft 3 1/2 in

How much further must ARTHUR jump to brake the record :

Long jump record - Arthur's best jump

[24 ft 9 1/4 in] - [24 ft 3 1/2 in]

24 ft - 24 ft = 0

9 1/4 in - 3 1/2 in

37 / 4 in - 7 /2 in

L. C. M of 4 and 2 = 4

A bottle is filled with 635 g of olive oil which has a density of 0.96 g/cm3. What is the volume of the olive oil ?

Answers

Answer:

The volume of the olive oil is 661.4583 cm³

Step-by-step explanation:

The rule of the density of an object is d = M ÷ V, where

M is the mass of the objectV is the volume of the object

∵ A bottle is filled with 635 g of olive oil

M = 635 g

∵ The olive oil has a density of 0.96 g/cm³

d = 0.96 g/cm³

→ Substitute them in the rule above

∵ 0.96 = 653 ÷ V

→ Multiply both sides by V

∴ 0.96 V = 635

→ Divide both sides by 0.96

V = 661.4583 cm³

The volume of the olive oil is 661.4583 cm³

one side of triangle =  6/2 =3 (half of the diagonal)

other side = 8/2 = 4
