<span>Mindy and troy combined 9 pieces of the wedding cake.
Mindy ate = 3 pieces of cake
Troy = had ¼ of the total cake.
Now, let’s find an equation that will give us the total number of pieces of the cake
=> Let X = Mindy
=> let Y = Troy
=> Let c = total number of cake
=> X + Y = 9, where x = 9 and y = ¼
Let’s find the number of pieces of cake that Troy’s have:
=> Y = 9 – x
=> Y = 9 – 3 = 6
=> Y = 6
Now, let’s find the number of Cake
=> 6 = c/4
=> c = 4 x 6
=> c = 24
Thus, there are 24 cakes in all.

Find the values of x and y

zhuklara [117]

You can use a tangent:

$tangent=\dfrac{opposite}{adjacent}$

We have opposite = 17 and adjacent = x.

$\tan30^o=\dfrac{\sqrt3}{3}$

substitute:

$\dfrac{17}{x}=\dfrac{\sqrt3}{3}$ cross multiply

$x\sqrt3=(3)(17)$ multiply both sides by √3

$x(\sqrt3)(\sqrt3)=51\sqrt3$

$3x=51\sqrt3$ divide both sides by 3

$x=17\sqrt3$

Use the Pythagorean theorem:

$y^2=(17\sqrt3)^2+17^2\\\\y^2=289(\sqrt3)^2+289\\\\y^2=289\cdot3+289\\\\y^2=867+289\\\\y^2=1156\to y=\sqrt{1156}\\\\y=34$

-------------------------------------------------------------------------------------------------

Other method.

$30^o-60^o-90^o$ triangle.

The sides are in the ratio $1:2:\sqrt3\to17:y:x$

Therefore

$17:(2\cdot17):(17\sqrt3)\to17:34:17\sqrt3\to x=34,\ y=17\sqrt3$

B. What number is equal to 280 tenths + 19 thousandths?<br><br> HELP!!

Kaylis [27]

The number that equals 280 tenths + 19 thousandths is 28.019

<h3>How to determine the number?</h3>

The statement is given as:

280 tenths + 19 thousandths

Rewrite the terms of the expression as fractions

So, we have

280/10 + 19/1000

Evaluate the quotients

28.0 + 0.019

Add both numbers

28.019

Hence, the number that equals 280 tenths + 19 thousandths is 28.019
