3y is 45% of what number

Mathematics
1 answer:
alexdok [17]2 years ago
6 0

Answer:

Call the number x and y. Then:

x - y = 45

and

x/y = 4, So x = 4y

Substitute 4y for x in the first equation:

4y - y = 45

3y = 45

y = 45/3 = 15

Substitute y = 15 in the first equation

x - 15 = 45

x = 45 + 15 = 60

So the two numbers are 60 and 15

Step-by-step explanation:

Every morning, halle goes to school with a 1-liter bottle of water. she drinks 1/4 of the bottle before school starts and 2/3 of
Nuetrik [128]
I think it's 1/6. Because before school she drinks 1/4 then before lunch she drink 2/3 if 1/4 so you would multiply. 1*2=2. 4*3=12. So you get 2/12 or if you simplify, 1/6

Anything can solve this
prohojiy [21]

Answer:

64.87° = 65°{ to the nearest degree}

Step-by-step explanation:

From the figure Catherine is standing 105m from the point B where the Ballon is; this description fits a= 105 m from the diagram.

Similarly Aisha is standing 95m from the point B where the Ballon is; this description fits c= 95 m from the diagram

A = ? ( The angle of elevation of Aisha towards the balloon)

C = 55°

From Sine rule

It states that the sine of an angle divided by its corresponding side is equal for all corresponding angles and sides along the triangle.

This is expressed mathematically as;

Sin A/ a= SinB/ b= SinC/c

We take the pairs of relevance;

Sin A/ a = SinC/c

There SinA = SinC/c × a

=Sin55/95 × 105

= 0.9053

A = Sin^(-1)[0.9053]

A = 64.87° = 65°{ to the nearest degree}
