Answer:

Option B (Lucy says to multiply 4 x 4 = 16 because 2 x 4 = 8.) is the solution.

Step-by-step explanation:

Let's have a look at the image they've provided. <em>(The identical picture is shown below. )</em>

$\left[\begin{array}{cc}2&8\\4&?\\5&20\end{array}\right]$

Do you see a pattern here? Concentrate on the second row rather than the first. Both integers are multiplied by four, therefore 4 x 4 must be multiplied.

$2 *4= 8\\5*4 = 20$

This indicates that option B is the right response. (Lucy says to multiply 4 x 4 = 16 because 2 x 4 = 8.)

Hope this helps! :D

Sandy has 16 roses,8 daisies, and 32 tulips. She wants to arrange all the flowers in bouguets. Each bouguet has the same number

avanturin [10]

Answer:

Greatest number of flowers that can be used in a bouquet is 8.

Step-by-step explanation:

In this question greatest number of flowers used in a bouquet will be decided by the "Greatest Common Factor" of the numbers of the flowers given.

So, factors of 16 = 1×2×2×2×2

Factors of 8 = 1×2×2×2

Factors of 32 = 1×2×2×2×2×2

Common factors = 1×2×2×2

Greatest Common Factor of these numbers will be = 1×2×2×2 = 8.

Therefore, greatest number of flowers that could be in a bouquet is 8.

The two stadiums with the largest capacities are Marshfield Stadium and Bowden Stadium. Marshfield Stadium has a capacity of 7,6

Rina8888 [55]

Answer: Capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.

Step-by-step explanation:

Let x = Capacity of Marshfield Stadium.

y = Capacity of Bowden.

As per given, we have

x - y = 7,675 (i)

x+y = 210,355 (ii)

2x = 218030 (iii)

$\Rightarrow\ x= \dfrac{218030}{2}\\\\\Rightarrow\ x= 109015$

Put value of x in (i) , we get

109015 - y = 7675

⇒ y= 109015 - 7675

⇒ y= 101,340

Hence, capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.

A researcher would like to estimate p, the proportion of U.S. adults who support recognizing civil unions between gay or lesbian

SOVA2 [1]

Answer:

(b) 4,445

Step-by-step explanation:

If the researcher would like to be 95% sure that the obtained sample proportion would be within 1.5% of p (the proportion in the entire population of U.S. adults), what sample size should be used?

Given a=0.05, |Z(0.025)|=1.96 (check standard normal table)

So n=(Z/E)^2*p*(1-p)

=(1.96/0.015)^2*0.5*0.5

=4268.444

Take n=4269

Answer:(b) 4,445

Natalie added 20 pieces of candy to a bowl. Two days later, half of the candy in the bowl is gone. If there are 14 pieces left i

Salsk061 [2.6K]

Answer:

8 pieces of candy

Step-by-step explanation:

Take the original amount of candy in the bowl to be $x$ .

It says that 20 pieces of candy were added, therefore there are $x+20$ pieces of candy in the bowl.

Half of the candy is gone, therefore $\frac{x+20}{2}$ pieces of candy are left in the bowl.

After half of the candy is gone, there are 14 pieces left, so we can say that $\frac{x+20}{2} =14$

Solve for $x$ :

$x+20 = 28$

$x=8$

I need to solve it and show all the steps

sp2606 [1]

First Step: What two multiples have perfects squares that equal 48 and 12? P.S They also need to have a common multiple so you can combine like terms in the end.

16*3=48
   4*3=12

Second Step: Now use those multiples to split up your square roots so you will have perfect squares.
2√48 + 2√12=
2√16 ×√3 + 2√4×√3=   Now Simplify!
2×4×√3 + 2×2×√3=   Multiply!
8√3 + 4√3

Third Step: Now that they look alike you can just add them.

  Answer: 12√3
