Question 4 Use the figure below to find the value of x and y

Mathematics
1 answer:
Tpy6a [65]3 years ago
4 0

Answer:

x=4, y=8

Step-by-step explanation:

step 1

Find the value of y

we know that

In the right triangle of the figure

cos(30\°)=\frac{4\sqrt{3}}{y}

Remember that

cos(30\°)=\frac{\sqrt{3}}{2}

so

\frac{\sqrt{3}}{2}=\frac{4\sqrt{3}}{y}

Simplify

y=8\ units

step 2

Find the value of x

In the right triangle of the figure

sin(30\°)=\frac{x}{8}

Remember that

sin(30\°)=\frac{1}{2}

so

\frac{1}{2}=\frac{x}{8}

x=4\ units

Pls answer this is due in 30 minutes
ziro4ka [17]

Answer:

1a) t = 0.17b

1b) $36.03

2) 51,167.50

Step-by-step explanation:

1a) 17% converted to a decimal (divide by 100) = 0.17. Multiply that by the amount of the bill (before tipping) to get the amount of the tip

1b) The bill of $248 represents the entire bill (100%) plus the tip amount (17%) which makes 117%. As a decimal, this is 1.17.

To find what the cost was without the tip, divide the bill total by 1.17

248/1.17 = 211.97. That was the bill before the tip was added.

248-211.97 = 36.03 was the tip added.

2) 5.5% converted to a decimal is 0.055

0.55 x 48,500 = 2667.50

$2,667.50 + $48,500 = 51,167.50

Or, you can use what we did in 1b, and his new salary is 1.055 times 48,500

1.055 x 48,500 = 51,167.50
