Answer:

10 square meters

Step-by-step explanation:

You can find the volume of a cylinder by multiplying the area of its base by its height. This can be shown by the equation: v = (pi(r^2))h, or 140 = 14x

If you divide 140 by 14, you can get the area of its base.

Answer:

$9\ bass$ and $3\ trout$

Step-by-step explanation:

Let

x-----> the number of bass

y----> the number of trout

we know that

$3x+y=30$ ----> equation A

$5x-y=42$ ----> equation B

Adds equation A and equation B

$3x+y=30\\5x-y=42\\--------\\3x+5x=30+42\\8x=72\\x=9\ bass$

Find the value of y

$3(9)+y=30$

$y=30-27=3\ trout$

Can someone help me on 6 please

scZoUnD [109]

Answer:

1) Inequality: 110x>150+85x

2) Solution: x>6, then Nadia would need to sell more than 6 ads per week in order for Choice A to be the better choice,

<u>Solution:</u>

Be x the number of ads Nadia sells

A) Choice A: $110 for each ad she sells. She would earn:

Ea=110x

B) Choice B: A weekly salary of $150, plus $85 for each ad she sells. She would earn:

Eb=150+85x

1) Write an inequality to determine the number of ads Nadia would need to seel per week in order for Choice A to be the better choice:

Ea>Eb

110x>150+85x

2) Solution

Solving for x: Subtracting 85x both sides of the equation:

110x-85x>150+85x-85x

Subtracting:

25x>150

Dividing both sides of the equation by 25:

25x/25>150/25

Dividing:

x>6

(6-5) × (4-2) + 12/4 = 5

ehidna [41]

$\\ \sf\longmapsto (6-5)\times (4-2)+\dfrac{12}{4}=5$

$\\ \sf\longmapsto 1(2)+\dfrac{12}{4}=5$

$\\ \sf\longmapsto 2+\dfrac{12}{4}=5$

$\\ \sf\longmapsto \dfrac{8+12}{4}=5$

$\\ \sf\longmapsto \dfrac{20}{4}=5$

$\\ \sf\longmapsto 5=5$
