Answer:
Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.
Step-by-step explanation:
Given that Juan invested $ 19000 in two mutual funds, and Fund A earned 7% profit during the first year, while Fund B earned 3% interest, if he received a total of $ 1042 profit, to determine how much she had invested in each mutual fund the following calculation must be performed:
19000 x 0.07 + 0 x 0.03 = 1330
15000 x 0.07 + 4000 x 0.03 = 1170
11000 x 0.07 + 8000 x 0.03 = 1010
11500 x 0.07 + 7500 x 0.03 = 1030
11800 x 0.07 + 7200 x 0.03 = 1042
Therefore, Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.
Answer:
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Step-by-step explanation:
m ∠A + m ∠B = 90° Complementary angles sum = 90°
7x + 4 + 4x + 9 = 90
11x + 13 = 90
11x = 77
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Check = angle A + angle B = 90° checked
product= multiplication.

"double" means 
28 should be your answer!
Answer:
sin A = 3/5
cos A = 4/5
tan A = 3/4
Step-by-step explanation:
Using the trigonometric ratios;
SOH CAH TOA
Sin A = opposite/hypotenuse
cos A = adjacent/hypotenuse
tan A = opposite / adjacent
From the diagram given;
opposite = 3 adjacent =4
We can find the value of the hypotenuse by using the Pythagoras theorem
opposite² + adjacent² = hypotenuse²
3² + 4² =hypotenuse²
9 + 16 =hypotenuse²
25 = hypotenuse²
take the square root of both-side
√25 = √hypotenuse²
5 = hypotenuse
hypotenuse = 5
sin A = opposite / hypotenuse
sin A = 3/5
cos A = adjacent/hypotenuse
cos A = 4/5
Tan A = opposite /adjacent
tan A = 3/4
I am confused what is your question then i will tell you the answer.
