So the total you spent on your shirts is 26.24 time 3

So it would look like 3(26.24).

So A and D are wrong

So now looking at the equality signs
< is less than
> greater then

You want to spend less then 100

So the answer is B. Hoped I helped

What is the equation in standard form of the line Y equals 1 / 9 x + 5

Juli2301 [7.4K]

Answer:

1/9x - y = -5

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Algebra I

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define equation

Slope-Intercept Form: y = 1/9x + 5

Step 2: Find Standard Form

Subtract 1/9x on both sides: -1/9x + y = 5
Multiply -1 on both sides: 1/9x - y = -5

In a lab, a scientist is growing bacteria for a study. The scientist begins with a bacteria

Diano4ka-milaya [45]

Answer:

The answer is below

Step-by-step explanation:

The growth of the bacteria is in the form of an exponential growth. It is given by the formula:

$P(t)=ae^{rt}\\\\where\ t\ is\ the\ number\ of \ hours, P(t)\ is\ the \ population\ at\ t\ hours\\\and\ a=population\ at\ start$

At 2 hours, the population is 62 cells, hence:

$P(2)=ae^{2r}\\\\62=ae^{2r}\ \ .\ \ .\ \ .\ (1)$

After another 2 hours (4 hours), the population is 1 million:

$P(4)=ae^{4r}\\\\1000000=ae^{4r}\ \ .\ \ .\ \ .\ (2)\\\\Divide \ equation\ 2\ by\ equation\ 1:\\\\\frac{1000000}{62}=\frac{ae^{4r}}{ae^{2r}} \\\\16129=e^{2r}\\\\ln(e^{2r})=ln(16129)\\\\2r=9.688\\\\r=4.844$

Put r = 4.844 in equation 1

$62=ae^{2*4.844}\\\\62=16129a\\\\a=0.003844$

$P(t)=0.003844e^{4.844t}\\\\at \ start,t=0\\\\P(0)=0.003844$

The diameter of the base of right cone 12 cm . The total surface area of the cone is 306 cm^2

inn [45]

A = πr² + πrl
306.00 = 3.14(6)² + 3.14(6)(l)
306.00 = 3.14(36) + 3.14(6l)
306.00 = 113.04 + 18.84l
- 113.04 - 113.04
192.96 = 18.84l
18.84 18.84
10.24 ≈ l
