Answer:

b

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

One way you could figure out if a graph is a function is by doing the vertical line test:

Put a vertical line across every x value, if there is more than one point within one of the lines, it is not a function.

Answer:

28.26

Step-by-step explanation:

3×3=9

9×3.14=28.26

Answer:

The answer is 28.26

Step-by-step explanation:

Why? Ok so here it is:

The formula is (pi)(r)squared

In this case, you will replace pi with 3.14 and replace r with 3 because that's the radius.

So it would be (3.14)(3)

You would get 9.42

Now you just need to square it

When squared, you'll get 28.26 inches squared

Answer:

the answer is 75

Step-by-step explanation:

225 ÷ 3

75

Answer:

75

Step-by-step explanation:

no.of candles he make in 3 hrs = 225

no. of candles he make in 1 hr = 225/3

= 75 candles

Answer:

B. 60deg

Step-by-step explanation:

Both the sum of the third angle in the triangle and x has to be 180deg, as they sum to a half angle;

and the sum of angles in any triangle is 180deg.

We know that x = 180deg - (180deg - 28deg - 32deg) = 180deg - 180deg + 28deg + 32deg = 60deg

Also, note that x is drawn as smaller than a right angle. Unless the picture was made specifically to confuse us, we know that the only answer could be B.

Answer:

The exterior angle measures 60°

Step-by-step explanation:

Using the angles we already have we can determine that the missing interior angle is 120 since the interior angles of a triangle add up to 180°. So the missing interior and and the missing exterior angle are supplementary meaning they add up to 180. so 180-120=60°

Answer:

$11

Step-by-step explanation:

Given data

Total amount=  $358

Monthly cell phone bill= $78

      Bill for the three months = 78*3= $234

      Electtrcilty bill = $135

      Total bills= $234+ $135=$369

Hence, the amount to be added= 369-358 =$11

Answer:

[tex]\huge \colorbox{blue}{B}[/tex]

Step-by-step explanation:

we are given the formula,Mass and volume

to find density we just need to substitute the value of mass and value and simplify it

[tex] \sf substitute \: the \: value \: of \: mass \: and \: volume : [/tex]

[tex] \quad \: \sf \dfrac{7.0 \times {10}^{24} \: kg }{3.5 \times {10}^{12} \: {km}^{3} } [/tex]

now we will use [tex]\dfrac{x^m}{x^n}=x^{m-n}[/tex] to simplify division

[tex] \sf simplify \: division : \\ \quad \: \sf 2 \times {10}^{24 - 12} \times \frac{kg}{ {km}^{3} } \\ \quad \tt 2 \times {10}^{12} \frac{kg}{ {km}^{3} } [/tex]

hence, our choice is [tex]B[/tex]

[tex]\quad\quad\quad\quad\tt{density = (\frac{7.0}{3.5 } = 2.0)}[/tex]

[tex]\huge\underline{\tt{\red{Explanation:}}}[/tex]

Given that the formula for density is equal to mass all over the volume.

We use this formula:

[tex]\boxed{\tt{density = \frac{mass}{volume} }}[/tex].

We substitute it like this:

[tex]\boxed{\tt{density = \frac{7.0 \times {10}^{24} \: kg}{3.5 \times {10}^{12} \: k {m}^{3} } }}[/tex]

Then, hence we got:

[tex]\boxed{\tt{density = 2.0 \times {10}^{12} \: \frac{kg}{k {m}^{3} }} }[/tex]

Answer: the answer is 16 I think

Step-by-step explanation:

Answer: 16 inches

a^2+30^2=34^2

a^2+900=1156

      -900 -900

a^2=256

Square both sides to cancel a^2

a=16

Hope I helped!

Answer:

15a² + 21a + 19 = 0

Step-by-step explanation:

Given

(4a + 3)² = (a + 5)(a - 2)

(4a + 3)(4a + 3) = (a + 5)(a - 2 ) ← expand both sides using FOIL

16a² + 24a + 9 = a² + 3a - 10 ( subtract a² + 3a - 10 from both sides )

16a² - a² + 24a - 3a + 9 + 10 = 0 ← collect like terms

15a² + 21a + 19 = 0

Answer:

5

Step-by-step explanation:

The equation of a line is y=mx+b. b is the y-intercept when the line is graphed. The y-intercept is when the line intersects the y-axis. m is the slope of the line. In the given equation, m is equal 5, thus the slope is 5.
