Which best explains the relationship between the two triangles below? A. ΔADC ~ ΔRTS because ∠A ≅ ∠R, ∠C ≅ ∠S, and ∠D ≅ ∠T. B. Δ

KonstantinChe [14]

Answer:

A. ΔADC ~ ΔRTS because ∠A ≅ ∠R, ∠C ≅ ∠S, and ∠D ≅ ∠T

Step-by-step explanation:

The alternative itself answers the question. Just remember that two triangles are similar if the only difference is size.

∠DCA = 32.3º and ∠RTS = 51.2º

Simplify 10 - [14 = (3 + 4) · 2]+3

lora16 [44]

Answer:

There is a typo near the equal sign.

There can be two different answers if we think that = sign as + or -.

First way: Making = as +

=> 10 - [14 + (3+4) x 2] +3

=> 10 - [14 + 7 x 2] + 3

=> 10 - [14 + 14] + 3

=> 10 - 28 + 3

=> 10 + 3 - 28

=> 13 - 28

=> -15

=> So, -15 is the answer if we consider "=" sign as "+" sign.

Second way: Making = as -

=> 10 - [14 - (3+4) x 2] + 3

=> 10 - [14 - 7 x 2] + 3

=> 10 - [14 - 14] + 3

=> 10 - 0 + 3

=> 10 + 3

=> 13

=> So, 13 is the answer if we consider "=" sign as "-" sign.

Jlenok [28]

Answer:

He have left 1250 milliliters of sport drink.

Step-by-step explanation:

Given:

Eduardo bought 2 litre sports drink for soccer practice during practice.

Eduardo drank 250 milliliters of sport drink then he drank another 1/2 liter.

Now, to find the milliliter of sport drink he have left.

Eduardo bought sports drink = 2 litre.

Now, to convert litre into milliliter by using conversion factor:

1 litre = 1000 milliliter.

2 liters = 2 × 1000 milliliters.

2 liters = 2000 milliliters.

Thus, Eduardo bought 2000 milliliters sport drink.

As, Eduardo drank 250 milliliters of sport drink.

So, to get the sport drink left after he drank we subtract 250 milliliters from 2000 milliliters:

$2000-250\\\\=1750\ milliliters.$

Thus, 1750 milliliters sport drink left.

Now, to get the sport drink left after he drank $\frac{1}{2} \ liter$ we subtract $\frac{1}{2} \ liter$ from 1750 milliliters:

$\frac{1}{2} \ liter =500\ milliliters.$

So,

$1750-500\\\\=1250\ milliliter.$

Therefore, he have left 1250 milliliters of sport drink.

Aliens have injected Ana with mathematical nanobots. These nanobots force Ana to think about math more and more. Initially, ther

Answer:

Math will take over Ana's brain at 4.4 hours

Step-by-step explanation:

Exponential Grow

The population of the nanobots follows the equation

$p(t) = 5\cdot 2^t$

We must find the value of t such that the population of nanobots is 106 or more, that is

$5\cdot 2^t\geq 106$

We'll solve the equation

$5\cdot2^t= 106$

Dividing by 5

$2^t= 106/5=21.2$

Taking logarithms

$log(2^t)= log(21.2)$

By logarithms property

$t\cdot log(2)= log(21.2)$

Solving for t

$\displaystyle t=\frac{log21.2} {log2}$

$t=4.4 \ hours$

Math will take over Ana's brain at 4.4 hours
