vampirchik [111]

Hey there mate ;)

<h3>Answer:- ( 10   20  10)</h3>

Explanation:-

As per question, we can solve by splitting 40 into :-

$10 \: \: \: \: 20 \: \: \: \: 10$

Proof:

● As its told that the second number must be twice the first number , which means 20 should be the double of 10 (Proved)

● Next it is told that the third number must be the same as first number, which means that 10 must be equal to 10, which is true.

So, the answer is (10 20 10)

Juliette [100K]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Total balance =$221.57

But,

The bank statement shows total balance= $203.73

Difference between them is still outstanding is given by

$221.57-203.73=\$17.84$

when we consider the option (a),

(which says I and III)

$20.25 check to the florist and $38.09 check deposit

So, it becomes in total

$38.09-20.25=\$17.84$

So, these two things are still outstanding because of this there is difference in balance .

So, option 'a' is correct.

In ΔFGH, the measure of ∠H=90°, the measure of ∠G=75°, and FG = 24 feet. Find the length of HF to the nearest tenth of a foot.

chubhunter [2.5K]

Answer:

HF ≈ 23.2 ft

Step-by-step explanation:

Using the sine ratio in the right triangle.

sin75° = $\frac{opposite}{hypotenuse}$ = $\frac{HF}{FG}$ = $\frac{HF}{24}$

Multiply both sides by 24

24 × sin75° = HF , thus

HF ≈ 23.2 ft ( to the nearest tenth )
