Two angles are complementary. One angle is twice the size of the other. The bigger angle measures

Answers

Sum of two angles that are complementary = 90°

Let the smaller angle be x .

Then the larger angle = 2x

Let us make an equation to find the measure of both the angles :-

[tex]2x + x = 90[/tex]

[tex]3x = 90[/tex]

[tex]x = \frac{90}{3} [/tex]

[tex]x = 30[/tex]

Which means :-

Measure of the small angle = 30°

Measure of the larger angle = 2 × 30 = 60°

Therefore , the measure of the bigger angle is 60° .

When solving for x, the sine of 33º is used. What other angle and trigonometric function could be used to solve for x? a. cos 57º c. tan 57º b. tan 33º d. cos 33º

A car is traveling at a steady speed. It travels 1(1/2) miles in 2(1/4) minutes. How far will it travel in 26 minutes? In 1 hour?

Answers

Answer:

17[tex]\frac{1}{3}[/tex]miles

40miles

Step-by-step explanation:

Given parameters;

Distance traveled by  the car = 1[tex]\frac{1}{2}[/tex]miles  = [tex]\frac{3}{2}[/tex]miles

Time taken = 2[tex]\frac{1}{4}[/tex]minutes  = [tex]\frac{9}{4}[/tex]minutes

Unknown:

Distance covered in 26minutes and in 1hr = ?

Solution:

Speed is the rate of change of distance with time.

   Speed  = [tex]\frac{distance}{time taken}[/tex]

A. Insert the parameters and find the speed;

   Speed  = [tex]\frac{\frac{3}{2} }{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex] x [tex]\frac{4}{9}[/tex] = [tex]\frac{2}{3}[/tex]miles/minutes

Distance covered in 26minutes;

   Distance  = speed x time

   Distance  = [tex]\frac{2}{3}[/tex] x 26  = [tex]\frac{52}{3}[/tex] miles  = 17[tex]\frac{1}{3}[/tex]miles

B. Distance covered in 1hr or 60minutes;

  Distance = [tex]\frac{2}{3}[/tex] x 60 = 40miles

Farmer Jane has many hens that have laid many eggs. Before the eggs hatch, Jane wants to
count how many eggs are blue, how many are brown, and how many are white.
Jane counts that, of all the eggs, 6 are blue and 25% are brown.
If 10% of the eggs are blue, how many of the eggs are white?
a) 15
b) 21
c) 39
d) 65

Answers

Answer:

The correct option is;

c) 39

Step-by-step explanation:

The given information are;

The number of eggs that are blue = 6

The percentage of eggs that are brown = 25%

The percentage of eggs that are blue = 10%

Let the number of eggs Jane has = X

Therefore;

10% of X = 10/100 × X = 6

X = 6 × 100/10 = 60

The number of eggs Jane has = X = 60

The percentage of the eggs that are white eggs = 100 - (The percentage of eggs that are brown + The percentage of eggs that are blue)

The percentage of the eggs that are white eggs = 100 - (10 + 25) = 65%

The percentage of the eggs that are white eggs = 65%

∴ The number of  eggs that are white = 65% of X = 65/100 × X= 65/100× 60 = 39 eggs

The number of  eggs that are white = 39 eggs.

Jackson wants to attend a 2-year technical college that costs $7,200 per year. His parents plan to contribute 50% of his tuition each year. Jackson wants to save money while working at his summer job for the next 2 years. How much will he need to save each summer in order to have enough money for his first year's tuition?

Answers

Answer:

$3600

Step-by-step explanation:

Given

Collège cost=$7,200

Collège cost for 2 years= $7,200x2=$14400

50% of the cost cost for 2 years= $7,200

So for the remaining $7,200 Jackson will need to sort it himself for the next two years

So that per year he must save 7200/2= $3600

Complete the following statement.
Find the quotient. 7200/9 =

Answers

Answer:

800

Step-by-step explanation:

9 goes into 72 eight times, nine goes into 0 zero times

The complete statement is as follows:

The quotient of, 7200/9 = 800.

Quotient is the result which we get by dividing the one number by the other.

Where, the number which is getting divided is known as 'dividend'  and the number which divides the dividend is known as 'divisor'.

So,

Quotient = Dividend ÷ Divisor.

Or,

[tex]\text{Quotient} = \frac{\text{Dividend}}{\text{Divisor}}[/tex]

In 7200÷9, 7200 is dividend and 9 is divisor. We have to find the quotient.

Applying the division on 7200 by 9.

Since, 9 is very less than 72. Take the first 2 digits.

72÷9 = 8

There is no remainder.

Now, take three digits:

720÷9 = 80

Still no remainder is here.

Move to the last digit (0) and apply division.

7200÷9 = 800

No remainder is there.

That means the quotient of, 7200 divided by 9 is 800.

Hence, the quotient of 7200/9 = 800.
