since we know that PQ and PR are twin sides, well, the angle they each make at the base are also twin angles, Check the picture below.

Answer: 60

Step-by-step explanation:

3 / 100 * x = 15

3x = 1500 multiply both sides by 100

x = 500

500x0.12 = 60

The 12 percentage of the number is A = 60

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let's call the number we're looking for N

We can set up an equation based on the information given:

0.03N = 15

To solve for N, we can divide both sides by 0.03:

N = 15 / 0.03

N = 500

So the number we're looking for is 500

Now , the percentage value is = 12 %

And , we can find 12% of that number by multiplying it by 0.12:

A = 0.12 x 500 = 60

Hence , 12% of the number is 60.

The required value of n for two similar pentagons is 15/4.

The scale factor is a type of measurement which is used to increase or decrease the size of an object keeping its shape as the same. It can be determined by taking the ratio of the new and the original dimension of the object.

The given two pentagons have similar shape because one has been scaled to get the other.

It implies that the ratio of the corresponding sides for them will be equal. It can be written as follows,

5/n = 3(¹/₃)/2(¹/₂)

=> 5/n = (10/3)/(5/2)

=> 5/n = 20/15

=> n = 15/20 × 5

=> n = 15/4

The equations that represent the line are:

B. 2x + 3y = –3

D. y + 3= –2/3(x – 3)

E. y – 1 = –2/3(x+3)

An equation that represents a line whose slope is given as m, and it intercepts the y-axis at b, is expressed in slope-intercept form as y = mx + b.

To find the equation of the given line above, pick two points on the line, (0, -1) and (-3, 1) and find the slope (m):

Slope of the line (m) = change in y / change in x = (1 - (-1)) / (-3 - 0)

Slope of the line (m) = 2 / -3

Slope of the line (m) = -2/3.

The line intercepts the y-axis at -1. This means the y-intercept of the line is b = -1.

To write the equation of the line, substitute m = -2/3 and b = -1 into y = mx + b:

y = -2/3x - 1

It can be rewritten as 2x + 3y = –3 in standard form, or as y + 3= –2/3(x – 3) or y – 1 = –2/3(x+3) in point-slope form.

Therefore the answers are:

B. 2x + 3y = –3

Use Pyramid Formua to get upper height.

And add with 5m lower height.

a) The vertex of the problem is given as follows: (220, -583), meaning that the minimum depth reached by the vertex is of 583 after 220 hours.

b) The submarine was submerged for 440.1 hours.

The quadratic function in this problem is defined as follows:

d(t) = 0.012t² - 5.29t.

Which gives the depth of the submarine after t hours.

The coefficients of the equation are given as follows:

a = 0.012, b = -5.29.

Then the t-coordinate of the vertex is given as follows:

t = -b/2a = 5.29/(2(0.012)) = 220.

The minimum depth is then of:

d(220) = 0.012(220)² - 5.29(220) = -583.

This is a concave up parabola, which is the reason why the vertex is a minimum.

The roots of the function are given as follows:

0.012t² - 5.29t = 0

t(0.012t - 5.29) = 0.

Hence:

Meaning that the submarine was submerged for 440.1 hours.

The solution of the given system of equation is (6, 12). So the option c is correct.

In the given question, Carissa works as a babysitter during her summer vacation.

She gets paid one rate for daytime hours and a higher rate for nighttime hours.

One week, she worked 12 daytime hours and 4 nighttime hours and earned $120.

The next week, she earned $60 for a total of 4 daytime hours and 3 nighttime hours.

Let x represent the hourly daytime rate and y represent her hourly nighttime rate.

The system of equations is

12 x + 4 y = 120……………(1)

4 x + 3 y = 60……………(2)

We have to find the solution to the system of equations.

To find the solution for the system of equation we solve the given equation using elimination method.

Multiply equation by 3 on both sides, we get;

12x + 9y = 180

Subtract equation 3 and 1

12x+9y-(12x+4y)=180-120

12x+9y-12x-4y=60

5y=60

Divide by 5 on both side, we get;

y=12

Now putting the value of y in equation 2

4x+3×12=60

4x+36=60

Subtract 36 on both side, we get

4x=24

Divide by 4 on both side, we get

x=6

What is a quadrilateral?

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined.

Given that ABCD is a quadrilateral.

The diagonal AC divides the quadrilateral into 2 triangles △ABC and △ACD.

The length of sides AC and CB of the △ABC is same. Thus △ABC is isosceles triangle. Therefore ∠BAC = ∠ABC = x°.

Similarly, the length of sides AC and CD of the △ADC is same. Thus △ADC is isosceles triangle. Therefore ∠CAD = ∠CDA = 66°

Given that ∠DCB = 90°.

∠A = ∠CAD + ∠BAC = 66° + x°

The sum of all interior angle of a quadrilateral is 360°.

Therefore,

∠A + ∠B + ∠C + ∠D = 360°

66° + x° + x° + 90° + 66° = 360°

Add to the like terms:

222 + 2x = 360

Subtract 222 from both sides:

2x = 138

one leg of a right triangle is 6 inches longer than the other leg, and the hypotenuse is 30 inches. Thus,

The lengths of the legs of the triangle are 18 inches,24 inches and  30 inches.

Three vertices make up a triangle, a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Given that,

one leg of a right triangle is 6 inches longer than the other leg.

hypotenuse is 30 inches.

Let assume, the other leg be x

It is given that, one leg of a right triangle is 6 inches longer than the other leg. So, One leg = x + 6

Since it is a right angled triangle,

h² = p² + b²

Where, h = hypotenuse

p = perpendicular

B = Base

So, (30)² = (x+6)² + x²

or, x = -24, 18

As, the length of side cannot be negative so x becomes 18.

Thus, x + 6 = 18 + 6 = 24 inches

Hypotenuse = 30 inches

Hence, the lengths of the legs of the triangle are 18 inches, 24 inches and  30 inches.

If the ratio of the measure of the three sides of the triangle is 9:7:5 and the perimeter is 191.1 inches, then the three sides of the triangle are 81.9 inches, 63.7 inches and 45.5 inches

The ratio of the measure of the three sides of a triangle = 9 : 7 : 5

Then three sides of the triangles = 9x, 7x and 5x

Where x is the constant

The  perimeter of the triangle = 191.1

The perimeter of the triangle is the sum of the three sides of the triangle

Then the equation will be

9x + 7x + 5x = 191.1

21x = 191.1

x = 191.1 / 21

x = 9.1

The first side = 9x

= 9 × 9.1

= 81.9 inches

The second side = 7x

= 7 × 9.1

C

Step-by-step explanation:

If you draw multiple vertical lines through each graph, C is the only graph that touches the line once. Which means it passes the vertical line test.

The correct option is c. It is a solution to f(x) = g(x) because it is the x-coordinate where the two graphs intersect.

x = −1 is also a solution to f(x) = g(x) because it is asking for the values of x that make f(x) equal to g(x). In this case, x = −1 is a value that makes both f(x) and g(x) equal to −1, so it is a solution to the equation f(x) = g(x).

The graph of f(x) = g(x) is simply the set of all points that are on both the graph of f(x) and the graph of g(x)

These points are the points where the two graphs intersect. In this case, the graph of f(x) = g(x) is a single point at x = −1, which is the x-coordinate where the two graphs intersect

Also, mass of Jupiter = 1.90*10²⁷ kg

Hence, ratio of mass of Earth to Jupiter is calculated by dividing mass of Earth upon the mass of Jupiter.

Ratio = (5.97*10²⁴/1.90*10²⁷ )
