Step-by-step explanation:

My brother, they would add to 180 :D

You can see, QTS is an obtuse angle, and the PTQ is smaller, but no matter what, if you add them, they will always add up to 180

Answer:

shorter side = 7 in

longer side = 12 in

Step-by-step explanation:

Let w = width

then w + 5 = length

The perimeter of the rectangle = 2 widths + 2 lengths.

So, w + w + w + 5 + w + 5 = 38  or 2w +2(w + 5) = 38 are two ways to write the equation to solve the problem.

Now 4w + 10 = 38

4w = 28

w = 7

w + 5 = 7 + 5 = 12

shorter side = 7 in

longer side = 12 in

Check:  7 + 7 + 12 + 12 = 38 = perimeter

Answer:

15 units

Step-by-step explanation:

split the figure into two figures

one with 4x3 and the other with 1x3

then find the area for each and add the areas to get total area

4x3=12

1x3=3

12+3=15

hope this helps have a blessed day :)

Answer:

The answer has to be 168

Step-by-step explanation:

To find the Area you need to multiply all the lengths of each side together.

So 3x4x2x7=168

Answer:

x² + 2x - 6

Step-by-step explanation:

= f(x) + g(x)

= (2x + 1) + (x² - 7)

= 2x + 1 + x² - 7  

= 2x - 6 + x²  

= x² + 2x - 6

Answer:

32 minutes

Step-by-step explanation:

There are 60 seconds in a minute

That means we will need to know how many feet he walks in a minute

So we would do 3 x 60 which equals 180 so he walks 180 ft per miute

Now we need to figure out how many minutes it took for him to walk 5760 ft.

So we would do 5760 ÷ 180 which equals 32

So the aswer is 32 minutes for him to walk 5760 ft.

Hope this helps

Answer:

  12.  median: AD; altitude: CE; midsegment: none

  13.  x = 2

Step-by-step explanation:

12. The median joins a vertex with the midpoint of the opposite side. Point D is identified as the midpoint of BC, so AD is the median.

An altitude is a segment from a vertex that is perpendicular to the opposite side. CE is an altitude of this triangle.

A midsegment joins midpoints of adjacent sides of the triangle. Only one midpoint (D) is identified in this triangle, so no midsegment can be named.

Additional comment: BF is an angle bisector. Perhaps that is what is intended in part (c). You may want to report this question to your teacher.

13. The base segment is twice the length of the midsegment:

  2(5x -3) = x +12

  10x -6 = x +12 . . . . . eliminate parentheses

  9x = 18 . . . . . . . . . .  add 6-x

  x = 2 . . . . . . . . . . . . .divide by 9

Answer:

the 9 in the tenths place is 10 times bigger than the one in the hundredths place

Step-by-step explanation:

The value of the 9 in the tenth place is "10 times" the value of the 9 in the hundredth place.

Place value strategies are defined as math strategies that use to assist you in resolving your elementary math problems, using your place values, such as tens and hundreds.

The decimal we are examining is 3.9928.

The 9 in tenth place has a value of 0.9.

The value of 9 in the hundredth place is 0.09

The fraction of the 9 in the tenth place is now the 9 in the hundredth place.

To get this, simply multiply the value of 9 in the hundredth place by the value of 9 in the tenth place.

Mathematically, that would be;

0.09/0.9 = 0.1 = 1/10

This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place

So you can complete the statement by dragging and dropping "10 times" into the response area.

Answer:

$477.92

Step-by-step explanation:

42.88 x 6= 257.28

28.58 x 7= 200.06

257.28+200.06=457.34

457.34 x .045= 20.58

20.58+457.34= 477.92

Answer:

Answer:

The answer is below

Step-by-step explanation:

A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base. Also, the angles on the same leg of a trapezoid (adjacent angles) are supplementary (add up to 180°).

In trapezoid MNPQ:

∠M + ∠Q = 180° (angles on the same leg are supplementary)

108 + (3x + 21) = 180

3x + 129 = 180

3x = 51

x = 17

Also:

∠N + ∠P = 180° (angles on the same leg are supplementary)

∠N + (4x - 15) = 180

∠N = 180 - (4x - 15)

∠N = 180 - 4x + 15

∠N = 195 - 4x

substitute x = 17°:

∠N = 195 - 4(17)

∠N = 127°

Answer:

The price of the bicycle after the discount is 357 lei

Step-by-step explanation:

The given question says, "The bicycle costs 420 lei. Its price is reduced by 15%. How much will the bike cost after the discount."

Cost price of the bicycle = 420 lei

Discount = 15%

We need to find the price of the bicycle after the discount. It can be calculated as follows :

[tex]P=420\times \dfrac{15}{100}\\\\=63[/tex]

Price = 420 -63

= 357 lei

Hence, the price of the bicycle after the discount is 357 lei.

Answer:

Step-by-step explanation:

Answer:

¼(√6 + √2)

Step-by-step explanation:

We want to find cos (π/12) in surd form.

Now, cos (π/12) can be expressed as;

cos [(π/4) - (π/6)]

Now, from trig derivations we know that;

Cos (A - B) = CosACosB + sinAsinB

Thus;

cos [(π/4) - (π/6)] = cos(π/4)Cos(π/6) + sin(π/4)sin(π/6)

Now, in surd form;

cos(π/4) = sin(π/4) = (√2)/2

Cos(π/6) = (√3)/2

sin(π/6) = 1/2

Thus, Plugging in relevant values to get;

cos(π/4)Cos(π/6) + sin(π/4)sin(π/6) = ((√2)/2 × (√3)/2) + ((√2)/2 × 1/2)

This gives;

((√6)/4) + ((√2)/4) = ¼(√6 + √2)

Department Store:

7(18.75)+8= 139.25

Gas Station:

18.75+22= 40.75

Step-by-step explanation:

The mistake is 7x+8+x+22 should not equal 90. It should equal 180 degrees because the two angles are supplementary angles. (It forms a straight line)

Correct equation and how to solve for X:

7x+8+x+22=180

8x+30= 180

8x= 150

x=18.75

Department Store:

7(18.75)+8= 139.25
