First, start off with the number of double basses. the question says there are 4. now, add up all of the numbers of instruments in order to find the total. 7+4+11+11+11=44 (three 11’s for the first violins, second violins and violas). now since you’re comparing the double basses to the total amount, the ratio is 4/44. You can also simplify this ratio by dividing both numbers by 4, which will become 1/11. Now, in order to find the decimal, just divide the fraction. 1/11=.09 repeating. Hope this helped!

your answer would be -2/5 I think

066666666666667.

I did that question before

Equation 1. X+y=18

Equation 2. X+2y=25

Lesser number is 7 and the greater number is 11

X=18-y

(18-7)+2y=25

Y=7

X+7=18

X=11

1)

90g strawberry jelly

6 sponge fingers

315ml custard

135g tinned fruit

2) 260 cm²

Step-by-step explanation:

1) 120/4 × 3

90g strawberry jelly

8/4 × 3

6 sponge fingers

420/4 × 3

315ml custard

180/4 × 3

135g tinned fruit

2) area = base × height

= 20 × 13

= 260 cm²

A. Equation 1: x + y = 18

Equation 2: x + 2y = 25

B. The lesser number is 7 and the greater number is 11

Step-by-step explanation:

We come up with two equations with the information:

Equation 1: x + y = 18

Equation 2: x + 2y = 25

We solve the equation by substituting x (which is in terms of y):

x = 18 - y

(18 - y) + 2y = 25

y = 7

Now we substitute y into Equation 1:

x + 7 = 18

x = 11

-2/5

This is the answer

QR = 22.4

Step-by-step explanation:

We would apply the law of Cosines which is expressed as

a² = b² + c² - 2abCosA

Where a,b and c are the length of each side of the triangle and A is the angle corresponding to a. Likening the expression to the given triangle, it becomes

QR² = RS² + QS² - 2(RS × QS)CosS

QR² = 35² + 40² - 2(35 × 40)Cos34

QR² = 1225 + 1600 - 2(1400)Cos34

QR² = 2825 - 2800 × 0.8290

QR² = 2825 - 2321.2

QR² = 503.8

QR = √503.8

QR = 22.4 to the nearest tenth

1)

80 = 2×2×2×2×5

2)

21 -- 11 -- 8 -- 40

21 -- 15 -- 24 -- 60

Step-by-step explanation:

80 = 2×2×2×2×5

Half Tuna white: 21

Half brown: 21

25% of 32

25/100 × 32 = 8

32-8 = 24

Total brown: (100-20)/2 = 40

Total white = 60

Cheese:

40 - 21 - 8 = 11

60 - 21 - 24 = 15

21 -- 11 -- 8 -- 40

21 -- 15 -- 24 -- 60
