Answer:

k = -4

Step-by-step explanation:

First multiply 3 for both sides of the equation:

- 9 = k - 5

Then isolate k to get

k = -4

Answer:

K is equal to -14

Step by step:

3 x 3 = 9

We need 3 wholes.

5 + 9 = 14

14 - 5 = 9

K represents -14

4% of 350 is 14 so he only sold 14

find area of 1 small bub

πr² = 3.14 × 3²

= 28.26 cm

area of 2 small bub

28.26 × 2 = 56.52 cm

area of big bub = area of 2 small bub

= 56.52

find radius by using formula

πr² = 56.52

r² = 56.52 ÷ 3.14

r² = 18

r = √18

r = 4.24 cm

round off to nearest cm

4.24 ≈ 4 cm

Answer:

Step-by-step explanation:

A triangle has 180 degrees in total. One of the angles are 145 degrees, so we can subtract and get 35 degrees. Then, it says that the remaining angles are in a ratio 2:3. So, we would have:

[tex]2x:3x = 35 \\2x+3x = 35\\5x=35\\x=7[/tex]

Now that we know what x is, we can multiply that to our ratio:

[tex]2\cdot7=14 \text{ degrees for the first angle}\\3\cdot7=21 \text{ degrees for the second angle }[/tex]

Answer:

y = 1/2x + 10

Step-by-step explanation:

(y-11)/(14-11) = (x-2)/(8-2)

(y-11)/3 = (x-2)/6

2y-22 = x-2

2y = x + 20

y = 1/2x + 10

Let m = slope of the line.

m = (14 - 11)/(8 - 2)

m = 3/6

m = 1/2

We now have the slope and the slope is 1/2.

We plug the slope and one of the point into the point-slope formula.

Here is the point-slope formula:

y - y_1 = m(x - x/_1)

I will use the point (2, 11).

y - 11 = (1/2)(x - 2)

y - 11 = (1/2)x - 1

Now we solve for y by adding 11 to both sides of the equation.

y = (1/2)x - 1 + 11

Answer: y = (1/2)x + 10

Answer:

0=7

Step-by-step explanation:

Distribute

4−5=2(2+1)

4−5=4+2

Add 5 to both sides of the equation

4 − 5 = 4 + 2

4 − 5 + 5 = 4 + 2 + 5

Simplify Add the numbers

Add the numbers

4 = 4 + 7

Result

Step-by-step explanation:

y = -3x + 4

A. works

x = 4

y = -8

-3(4) + 4

-12 + 4 = -8

B. doesn't work

x = 2

y = -10

Answer:

C. 74

Step-by-step explanation:

add up all the numbers but not the value so you have 18 numbers. divide that by 2 and get 9. so 74 is between 73 and 78 so it divides the 18 numbers evenly into 9 and 9.

are this the answers?  

Step-by-step explanation:

The value of x is 16 degrees and the measure of the arc DFG for circles of homework 2 are 1 6.056 times radius of circle.

The property of straight angle says that, the angle of a straight line is equal to the 180 degrees.

It can also be define as the sum of all the angle made on the straight line is equal to the 180 degrees.

For the first problem, the line GE, which is the diameter of the circle has two angles over it (x-3) degree and (12x-25) degrees.

For the diameter GE the sum of these two angle will be equal to 180 degrees. Thus,

[tex](x-3)+(12x-25)=180\\x-3+12x-25=180\\13x-28=180\\13x=180+28\\x=\dfrac{208}{13}\\x=16^o[/tex]

The value of mDE will be equal to (12x-25) as it is verticle angle of mGF. Thus,

[tex]arcDE=(12x-25)\\arcDE=(12(16)-25)\\arcDE=167^o[/tex]

Similarly the value of mEF

[tex]arcEF=(x-3)\\arcEF=(16-3)\\arcEF=13^o[/tex]

Let the radius of the circle is R. Then the measure of arc DFG is equal to the sum of areDEF and arc GF. Thus,

[tex]arcDFG=\dfrac{2\pi R}{2}+\dfrac{2 \pi R \angle GHF}{360}\\arcDFG=\dfrac{2\pi R}{2}+\dfrac{2 \pi R (167^o)}{360}\\arcDFG=6.056R[/tex]

For the second problem, the angle MN and QO are equal due to the vertical angle property. Therefore,

[tex](10x-45)=(6x-1)\\10x-6x=-1+45\\4x=44\\x=11[/tex]

The value of mMN is,

[tex]MN=(10x-45)\\MN=(10(11)-45)\\MN=65^o[/tex]

The value of NP using the property of straight line for line segment MP can be given as,

[tex]NP=180-MN\\NP=180-65\\NP=115^o[/tex]

Thus, the value of x is 16 degrees and the measure of the arc DFG for circles of homework 2 are 1 6.056 times radius of circle.

Step-by-step explanation:

Clustered data emerge when the data from the entire sample can be grouped into a variety of different categories, refers to as clusters. Each cluster involves numerous observations, giving the data a “clustered” or “hierarchical” structure, with each observations encapsulated within the cluster.

Also, if we plot a series of numbers on a graph and we will see several of our dots gathered together, we have a cluster

From the above definition of clustered data the only option that is fitting into it is option C .

Answer:

Number 7 is 48

I think number 5 is 49 I'm not for sure about this one.

Step-by-step explanation:

Number 7:

Since it's a 90 degree angle, you just add 19 + 23 which gives you 42. Subtract 42 from 90 and it gives you 48, the value of the variable.

Number 5:

Now I'm not for sure about this one because of the number 12 pointing to the connecting point. So, I'd rather not say how I did this one before I get you confused when you learn about this in the future.
