This answer is already to the nearest tenth. The 5 is in the tenth's place.

1962.5 is already rounded to the tenth so the answer stays the same

Answer:

D: 1/35

Step-by-step explanation:

First, you have to know how many marbles there are, and if you count them all up there are 15 marbles in total. Next, there are 3 blue marbles, so you would put the fraction as 3/15, or simplified to 1/5. Now, if you don't replace that blue marble, you now only have 14 marbles, and there are 2 yellow, which means you have a 2/14 chance of drawing a yellow marble, simplified to 1/7. But because there are two parts of the problem you are going to multiply 1/5 by 1/7 to get 1/35, which is your answer.

1. In Kite ABCD below, point E is the midpoint of segment BD. What are the

Anvisha [2.4K]

Answer:

The coordinates of point D( 4,4)

Step-by-step explanation:

Step(i):-

Given points are E(10,4) and B(16,4)

'E' is the mid-point of segment BD

Let D(x₁, y₁) be a point

E = midpoint of segment BD

$(10,4) = (\frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )$

$10 = \frac{x_{1} +16 }{2}$

20 = x₁ + 16

20-16 = x₁

x₁ =4

Step(ii):-

$\frac{y_{1} +y_{2} }{2} = 4$

$\frac{4 +y_{2} }{2} = 4$

4 + y₂ = 8

y₂ = 8-4 =4

The co-ordinates of point D( 4,4)

Answer: A factor is a number that divides into another number exactly and without leaving a remainder.

Most numbers have an even number of factors; however, a square number has an odd number of factors.

A ball is thrown from an initial height of 3 meters with an initial upward velocity of 30 m/s. The ball's height h (in meters) a

yanalaym [24]

$h=3+30t-5t^2\implies 13=3+30t-5t^2\implies 0=-10+30t-5t^2 \\\\\\ 5t^2-30t+10=0\implies 5(t^2-6t+2)=0\implies t^2-6t+2=0$

now, it doesn't give us nice looking integers, so let's plug that into the quadratic formula.

$~~~~~~~~~~~~\textit{quadratic formula} \\\\ \stackrel{\stackrel{a}{\downarrow }}{1}t^2\stackrel{\stackrel{b}{\downarrow }}{-6}t\stackrel{\stackrel{c}{\downarrow }}{+2}=0 ~\hspace{10em} t= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a} \\\\\\ t= \cfrac{ - (-6) \pm \sqrt { (-6)^2 -4(1)(2)}}{2(1)}\implies t=\cfrac{6\pm\sqrt{36-8}}{2}$

$t=\cfrac{6\pm\sqrt{28}}{2}\implies t=\cfrac{6\pm\sqrt{2^2\cdot 7}}{2}\implies t=\cfrac{6\pm 2\sqrt{7}}{2}\implies t=\cfrac{2(3\pm 1\sqrt{7})}{2} \\\\\\ t=3\pm \sqrt{7}\implies t= \begin{cases} 3+\sqrt{7}\\ 3-\sqrt{7} \end{cases}\implies t\approx \begin{cases} 5.65\\ 0.35 \end{cases}$
