Answer:

9 Quarters, 3 dimes

Step-by-step explanation:

$2.00 = 8 quarters

25cents = 1 quarter

$2 + 25 cents = $2.25

2.55 - 2.25 = .30

30cents = 3 dimes.

Hope this is right.

There were many ways to do this. But this is 1 way.

Cory has 66.92 centimeters (cm) of wire. He uses 2 pieces of the wire. Each piece he uses is 6.58 cm long. What is the length of
Alex73 [517]

Answer:

The length of the remaining wire is 53.8 centimeters

Step-by-step explanation:

Let us solve the question

∵ Cory has 66.92 centimeters of wire

∵ He uses 2 pieces of the wire, each piece he uses is 6.58 cm long

→ Find the length of the two pieces he uses

∵ He uses = 2 × 6.58

∴ He uses = 13.16 cm

∴ The length of wire he uses is 13.16 cm

→ The length of the remaining = the total length - the length he uses

∵ The length of the remaining = 66.92 - 13.16

∴ The length of the remaining = 53.76 cm

→ Round it to the nearest tenth of a centimeter

∴ The length of the remaining = 53.8 centimeters

∴ The length of the remaining wire is 53.8 centimeters

Please help me asap with my grade 11 trigonometry math! I'll give brainliest, please help, thank you. *URGENT*
tia_tia [17]

Answer:

37.8579

This value is approximate and rounded to four decimal places

===============================================

Explanation:

The tangent function is being applied to some unknown angle x. To isolate x, we undo whatever tangent is doing. So we apply the inverse function. Specifically the inverse tangent function. This is also known as "arctangent" and your calculator most likely shows it as a button with a "-1" exponent above the "tan"

So apply the arctangent to both sides to get

tan(x) = 0.7773

arctan(tan(x)) = arctan(0.7773)

x = 37.8579

During the week, Brittney earned 1/4 and 1/3 of her monthly bonus on two sales transactions. If those bonuses amounted to $840,
EleoNora [17]

Answer:

$142.86

Step-by-step explanation:

Let the bonus be x

This implies that

\frac{1}{3}x +  \frac{1}{4}x = 840

Multiplying through by the L. C. M(that is 12)

12 \times \frac{1}{3}x + 12 \times  \frac{1}{4}x = 12 \times 840

\implies4x + 3x=10080

\implies7x=10080

Dividing through by 7

\implies \frac{7x}{7}  =  \frac{10080}{7}

\implies x=142.86

Hence her monthly bonus was $142.86

Find the area of a parallelogram with sides of 6 and 12 and an angle of 60°.
ASHA 777 [7]
I think I got it. Correct me if I am wrong.

Parallelogram diagram I believe down below. We must find the height and then the area using Pythagorean theorem. Since the green shaded part is a 30-60-90 triangle, the base is 1/2 the hypotenuse, therefore it is 3. Now we calculate the height with it.

A^2 + B^2 = C^2
A^2 + 3^2 = 6^2
    A^2 + 9 = 36
          A^2 = 27
              A = 3√3

Therefore the height is 3√3

Now calculate the area using A = bh

A = bh
   = (12)(3√3)
   = 36√3

So the area is 36√3 square units.

I cannot be sure of this answer because you did not provide a diagram.
