If CR = 2, RA = 3 , and BC = 10, find CS. 4 6 6 2/3 15

OlgaM077 [116]

Answer:

CS = 4

Step-by-step explanation:

From the figure below;

Triangle ABC is similar to triangle RSC

Therefore, the ratio of the corresponding sides in the two triangles is equal;

That is;

$\frac{AB}{RS}=\frac{AC}{RC}=\frac{BC}{SC}$

In this case, CR = 2 , RA = 3 and BC = 10 we are required to determine CS

But; $\frac{AC}{RC}=\frac{BC}{SC}$

AC=CR + RA

= 5

Assuming CS is y, then

$\frac{5}{2}=\frac{10}{y}$

$y=\frac{10(2)}{5} \\ = 4$

Therefore, CS is 4

How do I solve x² - 10x-3=0

evablogger [386]

Answer:

x = 5±2√7

Step-by-step explanation:

This quadratic cannot be factorised via the factorisation method, so we use the quadratic formula :

x = $\frac{-b + \sqrt{b^{2} -4ac} }{2a}$ or x = $\frac{-b - \sqrt{b^{2} -4ac} }{2a}$

(The reason I did 2 equations is because brainliest does not allow me to do the ± in the equation insert thing )

x = $\frac{-(-10) + \sqrt{-10^{2} -4(1)(-3)} }{2(1)}$ or x = $\frac{-(-10) - \sqrt{-10^{2} -4(1)(-3)} }{2(1)}$

x = $\frac{10 + \sqrt{100+12} }{2}$ or x= $\frac{10 - \sqrt{100+12} }{2}$

x = $\frac{10 + {4\sqrt{7}} }{2}$ or x = $\frac{10 - {4\sqrt{7}} }{2}$

x = $5+2\sqrt{7}$ or x = $5 -2\sqrt{7}$

Hope this helped and brainliest please

The number of blueberry muffins that a baker makes each day is 40% of the total number of muffins she makes.

Mkey [24]

Answer:

Part A: 90; Part B: 24.

Step-by-step explanation:

The number of blueberry muffins is 40% of the total number of muffins.

Part A: There are 36 blueberry muffins. This is 40% of the unknown number of muffins, x; this gives us

36 = 0.4x

Divide both sides by 0.4:

36/0.4 = 0.4x/0.4

90 = x

There were 90 total muffins.

Part B: 40% of the total number of muffins, 60, gives us the unknown number of blueberry muffins:

0.4(60) = x

24 = x

There were 24 blueberry muffins.
