Answer:

2/5 is left

Step-by-step explanation:

Add the two you have so far together. 2/5+1/5=3/5

So 3/5 of your budget is used. 3/5 is a fraction, meaning that 5 is the whole.

Subtract 3 from 5 and you get 2. There are 2/5 left in the budget for everything else.

What is the solution to the equation 3 + 4 sqr root 4y = 4?
lawyer [7]

Answer:

1/64

Step-by-step explanation:

Given the expression

3+4√4y = 4

4√4y = 4-3

4√4y = 1

√4y = 1/4

Square both sides

(√4y)²= (1/4)²

4y = 1/16

y = 1/16 * 1/4

y = 1/64

Hence the value of y is 1/64

PLZ ANSWER QUICK-MATH TRIG
IRISSAK [1]

Answer:

FG = 9.7ft

Step-by-step explanation:

Find the diagram in the attachment.

The diagram is a right angled triangle since one of its angle is 90°

Using SOH CAH TOA to calculate the length FG which is the hypotenuse.

According to SOH

Sin∠G = Opposite/Hypotenuse

To get the ∠G,

∠F+∠H+∠G = 180°

18°+90°+∠G = 180°

∠G = 180°-108°

∠G = 72°

Sin72° = 9.2/FG

FG = 9.2/sin72°

FG = 9.67feet

FG = 9.7ft (to the nearest tenth of a foot)
