A triangle has an angle that measures 90°. The other two angles are in a ratio of 2:7. What are the measures of those two angles?

Answer: pretty sure the answer is D

Step-by-step explanation:

The length of the diagonal of Bob’s TV will be 50 in.

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Given that;

Bob’s rectangular TV is 40 inches wide and 30 inches high.

Now,

Since, TV is in rectangular shape.

Hence, It satisfy the Pythagoras theorem.

Let the length of the diagonal of Bob’s TV = x

So, We can formulate;

⇒ x² = 40² + 30²

⇒ x² = 1600 + 900

⇒ x² = 2,500

⇒ x = √ 2,500

⇒ x = 50 in

Thus, The length of the diagonal of Bob’s TV = 50 in.

Based on the equidistant chords theorem, the value of m and n in the circle are:

m = 7/4 = 1.75

n = 1/2 = 0.5

The equidistant chords theorem states that, two chords are congruent if they are equidistant to the center of the same circle.

Given:

Thus, since US = RU, therefore chords PO and EW are congruent based on the equidistant chords theorem.

Therefore:

3m + 2 = -m + 9

Add like terms

3m + m = -2 + 9

4m = 7

m = 7/4

m = 1.75

20n - 14 = -2(2n + 1)

20n - 14 = -4n - 2

20n + 4n = 14 - 2

24n = 12

n = 12/24

n = 1/2 = 0.5

Therefore, based on the equidistant chords theorem, the value of m and n in the circle are:

m = 7/4 = 1.75

n = 1/2 = 0.5

Answer:

x=7   y= -3

Step-by-step explanation:

When you ADD both the x variable is cancelled

since -3x + 3x = zero

then you solve for y  And when you plug the value of y you will solve x

     2y-3x =-27

     5y+3x =6

   ADD BOTH

    7y = -21

    y = -3

     PLUG y

5(-3)+3x  = 6

 -15 + 3x = 6

Answer:

132 cm²

Step-by-step explanation:

To find the area of the figure, start by dividing the figure into smaller rectangles.

Area of figure

= area of shaded rectangle +area of unshaded rectangle

[tex]\textcolor{steelblue}{\text{Area of rectangle= length ×breadth}}[/tex]

Shaded rectangle

Length= 4 cm

Breadth= 6 cm

Area

= 4(6)

= 24 cm²

Unshaded rectangle

Length= 9 cm

Breadth= 12 cm

Area

= 9(12)

= 108 cm²

After finding the area of each rectangle, we can add the two areas together to obtain the total area of the figure.

Area of figure

= 108 +24

= 132 cm²

First, let's convert the mixed numbers into improper fractions:-

Now, do the same for the second fraction:-

We know both b and h, so we can just plug in the values and solve:

Multiplying 13 times 23 is easier than multiplying 26 times 13.

Now, this can only be done if the numbers do have some common factors. Both fractions are now in simplest form; 13, 23, 3 & 2 don't have common factors.

Answer:

d 115.9

Step-by-step explanation:

The initial investment of Calvin must be increased by a factor of 115.927 % to equal Marquez's investment at any time. (Correct choice: D)

In this question we must apply the concept of compound interest to derive the initial investment to be done by Calvin. According to the statement, Calvin invests money five years later than Marquez.

To determine the initial investment to be deposited by Calvin such that his investment equals Marquez's investment at any time we resort to the following expression:

[tex]1500\cdot (1+0.03)^{t+5} = C_{C}\cdot (1+0.03)^{t}[/tex]     (1)

Then, we simplify the required initial investment:

[tex]C_{C} = 1500\cdot (1+0.03)^{5}[/tex]

[tex]C_{C} = 1738.911[/tex]

And the increase factor is:

[tex]r_{C} = \frac{1738.911}{1500}\times 100\,\%[/tex]

[tex]r_{C} = 115.927\,\%[/tex]

The initial investment of Calvin must be increased by a factor of 115.927 % to equal Marquez's investment at any time. (Correct choice: D) [tex]\blacksquare[/tex]

The other number is equal to x/2.

A fraction in mathematics represents a portion or element of the whole. It represents the appropriate parts of the totality. A fraction is made up of two parts: the numerator and the denominator.

As per the given data:

We are given the relationship between 2 numbers, It's given that One number is two times greater than another number.

The greater number = x

Let's assume that the smaller number is y.

From the given data in the question:

One number is two times greater than another number

= x = 2y ...(i)

The other number that is the smaller number is given by:

By dividing eq (i) by 2 from both sides.

y = x/2

The other number is equal to x/2

Answer:

t = 9

Step-by-step explanation:

the sum of the exterior angles of a polygon is 360°

sum the exterior angles and equate to 360

10t + 16t + 53 + 73 = 360 , that is

26t + 126 = 360 ( subtract 126 from both sides )

26t = 234 ( divide both sides by 26 )

t = 9

Answer:

91 degrees

Step-by-step explanation:

Angle RT = 46 degrees

Angle RU = 180 degrees

Angle RS = 89 degrees

So 46 + 89 = 135

180 - 135 = 45

So Angle UT = 45 degrees

Which means that Angle QR = 45 degrees also because they are vertical from each other

So you add 45 + 46 = 91

Angle TQS = 91 degrees
