Answer:

the 70

Step-by-step explanation:

basically yoy half it as an angle is either 180 for triangle 360 for a circle and 180 also for a half line\

Answer

1)90°. 2)51°. 3)39°.

Step-by-step explanation:

1) it is straight so it is 90°

2)51° because the kite is symmetrical so it should be the same as the other side

3)90+51=141

180-141=39° so it is 39°

Hope this helps :) good luck

Answer: 6.25(5) - 2.75 = X

Step-by-step explanation:

Each pond costs 6.25 and she buys 5 pounds so multiply 5.25 and 5. Then subtract 2.75 which is the coupon to get your answer.

The expression is 6.25x - 2.75 = P

P being the total cost

Answer:

Slope = 1.60

Step-by-step explanation:

y = 1.60x + 12

$12 - This would be the y-intercept

$1.60 - slope since it is the amount needed to pay each hour.

Hope this helps!

Answer:

(4.9793, 6.2207)

Step-by-step explanation:

Given the data:

Sample size, n = 34

Sample mean, m = 5.6

Standard deviation, s = 2.2

Confidence interval = 90%

Using the relation :

m ± Zcritical * s/√n

Zcritical at 90% confidence interval = 1.645

Confidence interval ;

5.6 ± (1.645 * 2.2/√34)

5.6 ± 0.6206533

Lower boundary = 5.6 - 0.6206533 = 4.9793

Upper boundary = 5.6 + 0.6206533 = 6.2207

Answer:

72°

Step-by-step explanation:

Find the image of the question attached

The sum of angle in a triangle is 180°

Hence:

15x+24x+21x = 180°

60x =180

x =180/60

x= 3

Get the largest angle

The largest angle out of the angles is 24x

24x =24(3)

24(3) =72°

Hence the measure of the largest angle is 72°

Answer:

Last option

Step-by-step explanation:

That is your best choice because that is the option that tells you the angles are congruent and not the sides. I could be wrong tho.

The hypothesis to proof that the base angles of the isosceles triangle are congruent will be AC≅AB

An isosceles triangle is a triangle that has at least 2 congruent sides. The congruent sides are the legs of the triangle while the remaining side is called the base. The angles on the base is called the base angles.

The base angles of an isosceles triangle are congruent. The base angles are

∠BCA and ∠CBA and they are congruent. The sides AC and AB are congruent. AC≅AB.

Therefore, the hypothesis to proof that the base angles of the isosceles triangle are congruent will be as follows:

Answer:

t > 1380

Step-by-step explanation:

Subtract 7200 from both sides

10t + 7200 - 7200 > 21000 - 7200

Simplify

10t > 13800

Divide both sides by 10

10t/10 > 13800/10

Simplify

t > 1380

Answer: the volume V generated by rotating the regions 281.49

Step-by-step explanation:

Given that;

the radius of the shell ⇒ (4 - x)  

then the circumference of the shell is 2π( 3 - x )  i.e 2π × radius

y = 0 and x = 2

the height of the shell is 3x⁴

Now the volume of the solid obtained by rotating

the bounded region about x = 4 is;

V = ²∫₀ 2π ( 4 - x ) ( 3x⁴ ) dx

= ²∫₀ 2π ( 12x⁴ - 3x⁵ ) dx

= 2π [ 12x⁵/5 - 3x⁶/6 ]₀²     {BY FTC -2]

= 2π [ (12×32)/5 - (3×64)/6 ] - ( 0-0) ]

= 2π [ 76.8 - 32]

= 2π [ 44.8 ]

= 281.49

Therefore the volume V generated by rotating the regions 281.49

Answer:

25000m/s

Step-by-step explanation:

The following formula is used to calculate the speed or velocity of a wave.

V = f * w

Where V is the velocity (m/s)

f is the frequency (hz)

w is the wavelength (m)

First, determine the frequency.

Calculate the frequency of the wave.

Next, determine the wavelength.

Calculate the wavelength of the wave.

Finally, calculate the wave speed.

Using the formula above, calculate the wave speed.

Hey there!

The answer to your question is y = -3/7x - 9/7

To answer this, we need to get y by itself on one side, so we need to solve for y:

3x - 7y = 9

-7y = 3x + 9

y = -3/7x - 9/7

Hope it helps and have an amazing day!

Answer:

No invariant point

Step-by-step explanation:

Yo!

When we translate a form, in this case a polygon We must observe the direction of the vector. Since our vector is:

1) Let's apply  that translation to this polygon, a square. Check it below:

2) The invariant points are the points that didn't change after the transformation, simply put the points that haven't changed.

Examining the graph, we can see that no, there is not an  invariant point, after the translation. There is no common point that belongs to OABC and O'A'B'C' simultaneously. All points moved.

I hope you understood !

We can write the question in the form of an equation:

  13/16 = n×1/8

Multiplying by 8 gives ...

  8×13/16 = n

  13/2 = n = 6.5

The number of 1/8 in 13/16 is 6 1/2 or 13/2.

Answer:

Step-by-step explanation:

The sum of exterior angles is 360°, so the exterior angle can be easiest to find first.

  exterior angle = 360°/72 = 5°

The interior angle is the supplement of this.

  interior angle = 180° -5° = 175°

The measure of one interior angle is 175°; one exterior angle is 5°.

Answer:

67 ≤ x ≤ 73

Step-by-step explanation:

The absolute value of a real number x is the non negative value of x. Therefore the absolute value of x (|x|) = x for x ≥ 0 and -x for x < 0.

An expression |x - a| = b signifies that x - a = b or -(x - a) = b

Given that |x − 70| ≤ 3, hence:

|x − 70| ≤ 3

x - 70 ≤ 3 or -(x - 70) ≤ 3

x ≤ 3 + 70 or x - 70 ≥ -3

x ≤ 73 or x ≥ -3 + 70

x ≤ 73 or x ≥ 67

67 ≤ x ≤ 73

Hence the solution of |x − 70| ≤ 3 is 67 ≤ x ≤ 73

Answer:

1/3 for a.

2/3 for b.
