Answer 1

Answer:

180

60

40

Step-by-step explanation:

Angles in a triangle add up to equal 90 degrees

Equilateral - has all congruent angles and congruent sides

If a triangle has 3 angles and the angles add up to equal 180 then the measure of one angle in an equilateral = 180 / 3 = 60

Bisect means to split into to equal parts

So if you bisect an 80 degree angles you will have two 40 degree angles. ( Because 80/2 = 40 )

Answer 2

Answer:

40°

Step-by-step explanation:

bisecting an angle gives equal angles equivalent to half the size of the bisected angle for each of them

-6x+y= -2
-3x-6y= 12

Answers

Answer:

Ans: x=0

       y= -2

Step-by-step explanation:

-6x+y= -2--------- (1) × 6

-3x-6y= 12--------(2) × 1

-36x+6y= -12-----(3)

-3x-6y= 12--------(2)

(3)+(2)

-36x+6y+(-3x-6y) = -12+12

⇒ -36x+6y-3x-6y = 0

⇒ -36x-3x = 0

⇒ -39x=0

⇒ x= 0/-39

∴ x = 0

Substitute x = 0 into (1)

-6x+y= -2

⇒-6(0)+y= -2

⇒0+y= -2

∴y = -2

Ans: x = 0

       y = -2

Check:

-6x+y= -2--------- (1)

= -6(0)+(-2)

= 0 - 2

= -2 ✔

-3x-6y= 12--------(2)

= -3(0)-6(-2)

= 22°. Which equation can you use to find the value of c = AB?


Answers

Answer:

7.7

Step-by-step explanation:

use law of cosines

c² = a² + b² - 2ab * cosC

c² =  16² + 10² - 2(16)(10)cos22

c² =  256 + 100 - 320 * 0.927183854566787

c² = 59.3011665386

c ≈ 7.7

Answer:

You can use the Law of Cosines to solve for c:

c2 = a2 + b2 − 2ab cos C = 162 + 102 − 2(10)(16) cos 22°.

Erica took out a loan to buy her new motorcycle. The purchase price of the motorcycle was $11349.00 plus 5% GST and 7% PST. She pays $409.00 per month on her loan, which has a term of 3 years. How much more is she paying than the purchase price? a. $2415.74 b. $1610.50 c. $2254.69 d. $2013.12

Answers

Answer:

The correct answer is D. $2,013.12.

Step-by-step explanation:

Since Erica took out a loan to buy her new motorcycle, and the purchase price of the motorcycle was $ 11349.00 plus 5% GST and 7% PST, and she pays $ 409.00 per month on her loan, which has a term of 3 years, for To determine how much more is she paying than the purchase price, the following calculation must be performed:

11,349 + (11349 x 0.12) = X

11,349 + 1,361.88 = X

12,710.88 = X

409 x 12 x 3 = X

4,908 x 3 = X

14.724 = X

14,724 - 12,710.88 = X

2,013.12 = X

Therefore, Erica is paying $ 2,013.12 more than the purchase price.

Step-by-step explanation:

QR= 1.5 inches

TS= 2 inches

TP= 3.8 inches

RS= 1.4 inches

PQ= 2.6 inches

now complete ur promise

Answer:

Step-by-step explanation:

Remark

The question says to increase the lengths of each side by a factor of 1.5.

That means that every measurement we see on the diagram is multiplied by 1.5

QR = given length times 1.5

given length = 1.5

QR = 1.5 * 1.5

QR = 2.25

TS = given length * 1.5

TS = 2 * 1.5

TS = 3

TP = given length * 1.5

TP given = 3.8

TP = 3.8 * 1.5

TP = 5.7

RS = given length * 1.5

given length = 1.4

RS = 1.4 * 1.5

RS = 2,1

PQ = given length * 1.5

given length = 2.6

PQ = 2.6 * 1.5

PQ = 3.9

QRST is a rhombus

Let’s look at the diagonals
Length QS = sr(4^2 + 0) = 4
Length RT = sr(0 + 6^2) = 6
This means it cannot be a square or rectangle as they both have equal length diagonals.

QS is horizontal (y values same)
RT is horizontal (x values same)
This means it is a rhombus because diagonals are perpendicular and different lengths.

Squares have perpendicular diagonals of same length
Rectangles have diagonals of same length but not perpendicular

Fruntum A bucket is 20cm in diameter at the open end,12cm in diameter at the bottom,and 16cm deep. To what depth would the bucket fill a cylindrical tin 28cm in diameter?

Answers

Answer:

The depth is 5.33cm

Step-by-step explanation:

Given

[tex]D =20cm[/tex] --- diameter at open end

[tex]d = 12cm[/tex] --- diameter at bottom

[tex]H=16cm[/tex] -- depth

[tex]d_c = 28cm[/tex] --- diameter of the cylinder

Required

The depth the bucket will fill the cylinder

First, calculate the radii at the ends of the bucket

[tex]R=D/2 =20cm/2 = 10cm[/tex]

[tex]r=d/2 =12cm/2 = 6cm[/tex]

The volume of the bucket (frustum) is:

[tex]V = \frac{1}{3} \pi H(R^2 + Rr + r^2)[/tex]

[tex]V = \frac{1}{3} *\pi * 16 * (10^2 + 10*6 + 6^2)[/tex]

[tex]V = \frac{1}{3} *\pi * 16 * 196[/tex]

[tex]V = 1045.33\pi cm^3[/tex]

The volume of a cylinder is:

[tex]V = \pi r_c^2h_c[/tex]

Where:

[tex]r_c = d_c/2 = 28cm/2 =14cm[/tex]

So, we have:

[tex]1045.33\pi = \pi * 14^2 * h_c[/tex]

[tex]1045.33\pi = \pi * 196 * h_c[/tex]

[tex]1045.33\pi = 196\pi * h_c[/tex]

Make h the subject

[tex]h_c = \frac{1045.33\pi}{ 196\pi}[/tex]

[tex]h_c = \frac{1045.33}{ 196}[/tex]

[tex]h_c = 5.33[/tex]

QUESTION:
The angled of a triangle are (x-40), (x-20), (1/2- 10), find x

Answers

Answer:

x=124.75

Step-by-step explanation:

Sum of angles of a triangle=180°

(x-40)+(x-20)+(1/2- 10)=180°

(x-40)+(x-20)+(−9.5)=180°

x-40+x-20−9.5=180°

x+x-40-20-9.5=180°

2x−69.5=180°

2x=180°+69.5

2x=249.5

2x/2=249.5/2

x=124.75

Em uma competição esportiva uma equipe ganhou 80 medalhas sendo que 25% de ouro 35% de prata e o restante de blusa e qual o número de medalhas de bronze que essa equipe ganhou

Answers

Answer:

32 medals

Step-by-step explanation:

Given that

The team wons 80 medals

out of which 25% is gold

35% is silver

and rest is bronze

we need to find out the number of bronze medals that win by the team

The total percentage is 100

So, the remaining percentage is

= 100 - 25 - 35

= 40%

So, the number of bronze medal should be

= 40% of 80 medals

= 32 medals

A parallelogram has an area of 300 square kilometers and a height of 20 kilometers. What is the length of the base?

Answers

Answer: the length of the base is 15 kilometers.

Step-by-step explanation:

formula : Area of parrallelogram  = Length of base x height

Given: Area of parallelogram = 300 square kilometers

height = 20 kilometers

Substituting values in the formula , we get

300 = Length of base x 20

Length of base  = [tex]\frac{300}{20}[/tex]

= 15 kilometers

Answers

Answer:

Option C.

Step-by-step explanation:

We know that, for a value a > 1.

if b > c, then:

a^b > a^c

Now, this means that if we have two functions:

f(x) = x^n

g(x) = x^m

and m > n

then for large values of x, g(x) will be larger than f(x), because g(x) has a larger exponent.

now, is also true that:

f(x) = x^n

g(x) = n^x

for n > 1

For large values of x, g(x) will be larger than f(x), again, because for larger values of x g(x) will have a really large exponent, thus it grows really fast.

Then we can conclude that for the functions:

f(x) = 3*x

g(x) = 3*x^2

h(x) = 2^x

For a given value of x, h(x) will exceed the other two functions.

This can be seen in the graph below, where:

h(x) is purple, g(x) is blue, and f(x) is green.

We can see that eventually, h(x) exceeds the other two.

The correct option is C.
