Fiona, Peter and Angad share some sweets in the ratio 4:5:1. Fiona gets 40 sweets. How many sweets are there altogether?
steposvetlana [31]

Answer:

100

Step-by-step explanation:

sum the parts of the ratio, 4 + 5 + 1 = 10 parts

Fiona  gets 40 sweets which is 4 parts of the ratio

Divide Fiona's share by 4 to find the value of one part of the ratio

40 ÷ 4 = 10 ← 1 part of the ratio

The total number of sweets is 10 parts , thus

number of sweets in total = 10 × 10 = 100

Use the relationship between the angles in the figure to answer the question.
Anuta_ua [19.1K]

Answer:

37+x+53 = 180

x=90

Step-by-step explanation:

To find x, we need to use the fact that a straight line equals 180 degrees.

37+x+53 = 180

Combining like terms

90+x = 180

Subtract 90 from each side

90-90+x = 180-90

x = 90

Cos^-1(-x)=-Cos^-1x for -1<x<1 TRUE OR FALSE?
VMariaS [17]

We are given

cos^{-1}(-x)=-cos^{-1}(x)

Firstly, we will simplify left side

and we will check whether it is equal to right side

Left side:

Let's assume y left side expression

y=cos^{-1}(-x)

now, we can take cos on both sides

cos(y)=cos(cos^{-1}(-x))

we can simplify it

cos(y)=-x

Right side:

Let's assume y left side expression

y=-cos^{-1}(x)

Multiply both sides by -1

-y=cos^{-1}(x)

now, we can take cos on both sides

cos(-y)=cos(cos^{-1}(x))

we can simplify it

cos(-y)=x

cos(y)=x

we can see that

both sides cos(y) value is different

so, this is FALSE.........Answer
