34% of what number is 51

1 answer:

5 0

150%

Get 150 and multiply it by (34/100).
In other words, do this: 150 x 0.34 (The 0.34 represents 34%. 0.76 would be 76%, etc) 
This gives you: 51

Simplify 2(a+5)−3(5a−4)

Nutka1998 [239]

Answer:

$-13a+22$

Step-by-step explanation:

we have

$2(a+5)-3(5a-4)$

step 1

Apply the distributive property both terms

$2a+2(5)-3(5a)+3(4)$

$2a+10-15a+12$

step 2

Combine like terms

$(2a-15a)+(10+12)$

$(-13a)+(22)$

$-13a+22$

A tank contains 300 liters of fluid in which 40 grams of salt is dissolved. Brine containing 1 gram of salt per liter is then pu

bonufazy [111]

Answer:

A(t) = 300 -260e^(-t/50)

Step-by-step explanation:

The rate of change of A(t) is ...

A'(t) = 6 -6/300·A(t)

Rewriting, we have ...

A'(t) +(1/50)A(t) = 6

This has solution ...

A(t) = p + qe^-(t/50)

We need to find the values of p and q. Using the differential equation, we ahve ...

A'(t) = -q/50e^-(t/50) = 6 - (p +qe^-(t/50))/50

0 = 6 -p/50

p = 300

From the initial condition, ...

A(0) = 300 +q = 40

q = -260

So, the complete solution is ...

A(t) = 300 -260e^(-t/50)

___

The salt in the tank increases in exponentially decaying fashion from 40 grams to 300 grams with a time constant of 50 minutes.

4^3-(84÷14)^2 Please help! Show work too! thank you!! <3

ANEK [815]

Answer:

$28$

Step-by-step explanation:

$4^{3}-(84\div14)^{2}$

Calculate 4 to the power of 3 = 64

$64-(\frac{84}{14} )^{2}$

Divide 84 by 14 = 6

$64-6^{2}$

Calculate 6 to the power 2 = 36

$64-36$

$=28$

Which of the following could not be a value of x? a -10 b-9 c-10.5 d-9.5

maw [93]

We know that sum of two sides in any triangle must be greater than the measure of third (longest) side otherwise triangle will not be formed.

According to picture longest side is 18

So this triangle must follow inequality

9+x>18

or 9-9+x>18-9

or x>9

that means value of x must be more than 9.

choices a, c, d are greater than 9 except choice b

Hence choice B-9 is the final answer.
