Mathematics
1 answer:
Dvinal [7]3 years ago
5 0

Answer:

Step-by-step explanation:

m∠B = 90°

m∠C = 90° - 27° = 63°

cos27° = \frac{200}{b} ⇒ b ≈ 224.5

sin27° = \frac{a}{b} ⇒ a ≈ 101.9

A sample of paint contains 3 ounces of blue paint and 8 ounces of yellow paint. If you have a 24 ounce can of the blue paint, ho
telo118 [61]

Answer:

64 ounces

Step-by-step explanation:

Given.

Represent blue with b and yellow with y

b = 3

y = 8

Required

What's the value of y when b = 24

Represent the given and required parameters as ratio

3 : 8 and 24 : y

Turn the ratio to an equation

3 : 8 = 24 : y

Represent as fraction

⅜ = 24/y

Multiply both sides by y

⅜y = 24

Make y the subject

y = 24 * 8/3

y = 64

Hence:

64 ounces of yellow paints is required for 24 ounces of blue paints

The coordinates of point t are (0,2) the midpoint of st is (6,3) find the coordinates of point s
kotykmax [81]

Answer:

(12,4)

Step-by-step explanation:

*Noted that we have to use formula of midpoint*

Given point t =(0,2)

Midpoint of st=(6,3)

So to find x coordinate of s,

By using formula of midpoint,

(0+x)/2 = 6

x= 12

To find y coordinate of s,

(2+x)/2 = 3

2+x= 6

x =4

Hence the coordinate of s is (12, 4)

A hot piece of metal is cooling at a constant rate of 10 *c per minute
timurjin [86]

The interpretation of -10c/60 seconds is that the metal loses 10 degrees Celsius every 60 seconds

<h3>How to interpret the expression?</h3>

The expression is given as:

-10c/60 seconds

From the question, we understand that:

The temperature decreases by 10c every minute

When converted to seconds, we have:

10c/60

Hence, the interpretation of -10c/60 seconds is that the metal loses 10 degrees Celsius every 60 seconds

Amy used a total of 7 1/4 gallons of gas while driving her car. Each hour she was driving, she used 5/6 gallons of gas. What was
nika2105 [10]

Answer:  8  7/10  hours

whole part = 8

fractional part = 7/10

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

Work Shown:

x = number of hours driving

(5/6)x = total number of gallons of gas used

(5/6)x = 7 & 1/4

(5/6)x = 7 + 1/4

(5/6)x = 28/4 + 1/4

(5/6)x = 29/4

x = (29/4)*(6/5)

x = (29*6)/(4*5)

x = 174/20

x = 87/10

x = (80+7)/10

x = 80/10 + 7/10

x = 8 + 7/10

x = 8 & 7/10

This is the same as writing 8  7/10

Amy drove 8 full hours, plus an additional 7/10 of an hour.

That mixed number converts to the decimal value 8.7
