Quadrilateral QRST is a square. If the measure of QR 3x-6 and TS is 6-x. Find the value of x.

Answer:

x = 55

Step-by-step explanation:

A triangle equals 180 degrees, b will be used to find the missing angle.

21 + 34 + b = 180

55 + b = 180

subtract 55 from both sides

b = 125

A straight line is 180 degrees and the b, the missing angle, and x are supplementary angles so

125 + x = 180

x = 55

the length of the side x will be 3.61 mm and the length of the side y will be 7.48 mm.

We are given the two right angle triangles.

For the smaller triangle:

Side 1 = 3 mm

Side 2 = 2 mm

Side 3 = x mm

Now, by using the Pythagoras theorem, we get that:

3² + 2² = x²

x² = 9 + 4

x² = 13

x = √13 mm

x = 3.61 mm

For the larger triangle:

Side 1 = 5 mm

Side 2 = y mm

Side 3 = 9 mm

Now, by using the Pythagoras theorem , we get that:

5² + y² = 9²

y² = 81 - 25

y² = 56

y = √56 mm

y = 7.48 mm

Therefore, we get that, the length of the side x will be 3.61 mm and the length of the side y will be 7.48 mm.

Step-by-step explanation:

F(3) find f(x) = -5x - 2

As u can see instead of x inside the parentheses it's a 3, meaning we have to replace x with 3 in the equation

f(3) = -5x - 2

f(3) = -5(3) - 2

f(3) = -15 - 2

f(3) = -17

The expression which represents the total owed for 6 months of a cable according to the description as in the task content is; 6(c) +50.

According to the task content; the expression that represents the total owed for 6 months of cable at a price of c dollars for each month, plus a one-time equipment fee of $50 is to be determined.

Hence, since the one-time equipment fee is; 50$ and it costs c dollars per month, the total cost for all six months is;

= (6×c) + 50

= 6(c) +50.

Answer:

m∠3 = 49°

Step-by-step explanation:

From the picture attached,

lines m and n are the parallel lines and line t is a transversal line intersecting these parallel lines at E and B respectively.

Therefore, ∠DEF ≅ ∠ABC [Exterior alternate angles]

m∠1 + m∠2 = m∠4 + m∠5

m∠4 = m∠5 [line s bisects ∠ABC]

50° + 48° = m∠4 + m∠4

98° = 2m∠4

m∠4 = 49°

Since, ∠4 ≅ ∠3 [Vertically opposite angles]

m∠3 = 49°

Answer:

Step-by-step explanation:

Correlation coefficient is the leading coefficient of the line of best fit. We can estimate the slope by looking at the plots. The plots are moving in a positive slope so we can remove B and C and E.

We're left with slope of 1 and 0.5

We can faintly imagine the line of slope 1. It doesn't really fit. SO it is 0.5

Calculation for the amount of Depreciation that Calvin may claim 2018 Using the half-year convention

Based on the information given we were told that he purchased a new office desk at the amount of $2,373 which means that the new office desk using the half-year convention will be a 7 year property.

Hence,

The Standard Depreciation percentage of the new office desk which is a 7 year property is 14.29% based on this the amount of Depreciation that Calvin may claim 2018 Using the half-year convention will be calculated as:

Using this formula

Depreciation=Cost of new office desk* New office Desk Depreciation percentage

Let plug in the formula

Depreciation=$2,373*14.29%

Depreciation=$339

Therefore Using the half-year convention Calvin may claim 2018 depreciation in the amount of $339
