Step-by-step explanation:

A. Line up the decimals, then multiply as you would with whole numbers:

$21.33 \\\times 2.04 \\ = 43.5132$

B. Line up the decimals, then add as you would with whole numbers:

Note: These decimals aren't lined up exactly.

$1.115 \\ + 3.18 \\ = 4.295$

$22.061 \\ + 4.295 \\ = 26.356$

$26.356 \\ + 12.2384 \\ = 38.5944$

Find the circumference and area of a circle with a radius of 3

viktelen [127]

Answer:

circumference is 18.84

area is 28.26

Step-by-step explanation:

circumference of a circle is

2πr where r is radius

= 6×3.14= 18.8

area of a circle is πr²

= 3×3×3.14

= 28.26

use π = 3.14

If m<1=6x+50 and m<2=4x+40 find x

Pepsi [2]

$\text{Adjacent angles on a straight line sum up to 180} \textdegree$

$\text{Therefore }\measuredangle 1 + \measuredangle 2 = 180 \textdegree$

$\text {Since } \measuredangle 1 = 6x+50 \text { and } \measuredangle 2 = x+40$

$(6x+50) + (4x+40) = 180$

$6x+50 + 4x+40 = 180$

$10x+90 = 180$

$10x = 180 - 90$

$10x = 90$

$x = 9$

Answer: x = 9

Please help me out with these 2 questions! Legit answers only please!

Answer:

1.) 12 hours 2.) She made a multiplying error in the table.

Step-by-step explanation:

1.)

First, let's find the slope of this equation:

m = 135 - 81 / 5 - 3

m = 54/2

m = 27

Therefore, the equation should be y = 27x.

Now we substitute 324 for y and solve for x:

324 = 27x

12 = x (Divided 27 on both sides.)

Therefore, someone would have to work 12 hours in order to earn $324.

2.)

For this problem, it appears Amanda has found the correct equation for her recipe. When taking a look at the table, however, it seems as though she has made a multiplying error.

djyliett [7]

Answer:

More than 50% would germinate

Step-by-step explanation:

Given that in the production of a plant, a treatment is being evaluated to germinate seed. From a total of 60 seed it was observed that 37 of them germinated

Let us check whether more than 50% will germinate using hypothesis test

$H_0: p = 0.50\\H_a: p>0.50\\$

(right tailed test)

Sample proportion p = $\frac{37}{60} =0.617\\q = 0.383\\Std error = \sqrt{\frac{pq}{n} } =0.0628$

p difference = 0.117

Test statistic Z = p difference/std error = 1.864

p value =0.0312

Since p value <0.05 our significance level of 5% we reject null hypothesis

It is possible to claim that most of the seed will germinate (i.e. more than 50%)
