Matthew made a fruit salad, in which the ratio of blueberries to red grapes is 8: 6. if matthew used 36 red grapes and the rest were blueberries. how many pieces of fruit are in matthew’s fruit salad? [type your answer as a number.]

  84

Step-by-step explanation:

Given : Matthew made a fruit salad, in which the ratio of blueberries to red grapes is 8:6.

It can be written as    (1)

Matthew used 36 red grapes and the rest were blueberries.

Let x be the number of blueberries.

Then, the ratio of blueberries to red grapes =      (2)

Now, from (1) and (2) , we have

i.e. Number of blueberries =48

Thus, the number of pieces of fruit are in Matthew’s fruit salad =48+36=84

Hence, number of pieces of fruit are in Matthew’s fruit salad=84

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
