m∠BAC = ?
A.) 15
B.) 30
C.) 45
D.) 60

MBAC = ?A.) 15 B.) 30 C.) 45 D.) 60

Answers

Answer 1

Answer:

B.) 30°

Step-by-step explanation:

We know from the property of 30°x60°x90° right triangle:

The hypotenuse is twice the leg which is opposite to 30 angle.

We see AC = 2*BC, therefore:

m∠BAC = 30°

Correct choice is B

Answer 2

The ratio of angles is directly proportional to the ratio of sides

<B=90°

The ratio of sides here is 1:1/2:1

Now

m<BAC be x

[tex]\\ \sf\longmapsto 2x+x=90°[/tex]

[tex]\\ \sf\longmapsto 3x=90[/tex]

[tex]\\ \sf\longmapsto x=30[/tex]

Find the perimeter of the triangle.

inches.

Answers

To get the perimeter, you simply add the following sides. Set up your equation as P = 7+(x+4)+(4x+1). Then add up like-terms. You should get P = 5x+12.

The perimeter of the given triangular image will be 5x + 12.

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

As per the given triangular triangle,

Perimeter = 7 + (x + 4) + (4x + 1)

Perimeter = 7 + 5x + 5

Perimeter = 5x + 12

Hence "The perimeter of the given triangular image will be 5x + 12".

Compensation
10. You have a choice of receiving a wage of $34,000 per year, $2840 per month, $650 per week, or $18
per hour. Which pay choice would you take? Assume a 40-hour work week with 52 weeks per year.

Answers

Answer:

Step-by-step explanation:

Monthly rate:

So if we convert $2840 per month into year that would be: 2840 * 12 (that's how many months in a year) = 34,080

Weekly rate:

There are approximately 4.345  weeks per month since it sometimes changes. So, to find the wage per month: 650 * 4.345  = 2824.25. To find the yearly rate multiply it by 12. So, 2824.25 * 12 = 33,891

Hourly rate:

Yearly Salary : $35,100

$18 per hour

The rectangle shown has a perimeter of 64 cm and the given area. Its length is 8 more than five times its width. Write and solve a system of equations to find the dimensions of the rectangle.

Answers

Answer:

Length 28 cm, width 4 cm

Step-by-step explanation:

Given:

P = 64 cmL = 5W + 8

Simplify equation for perimeter and solve for W:

P = 2(L + W) = 2(5W + 8 + W) = 2(6W + 8) = 12W + 1612W + 16 = 6412W = 48W = 4 cm

Find L:

Answer:

Step-by-step explanation:

Give brainliest please :)

0.00359, when rounded to nearest thousandth results in 0.0036.

What is Rounding Off?

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc. Rounding off numbers is done to preserve the significant figures.

Given, value to be rounded is : 0.00359

Since, 1 ten thousands = 10000 (104). So, 1 ten thousandth = 0.0001 (10-4)

Therefore, while rounding to nearest ten thousandth, we round the fractional part(or decimal part) upto 4 digits.

Here, In 0.00359, the digit after ten thousandth place is 9, which is (equal to or greater) than 5. So, 5 can be rounded to 6.

Hence, finally, 0.00359, when rounded to nearest thousandth results in 0.0036
