Answer:

648

Step-by-step explanation:

Step 1:

First, make an equation:

3⁴ · 2³

Step 2:

Then, simplify both factors:

3⁴ = 81

2³ = 8

Step 3:

Finally, multiply the numbers together:

81 · 8

Step-by-step explanation:

Answer:

Use a proportion::

time/dist = time/distance

t/1.5 = 1/30

t = 1.5/30

t = 15/300

t = 1/20 = 5/100 = 0.05

So A-0.05 is the final answer

Answer:

√52 units

Step-by-step explanation:

Here we want to find the distance between two points;

O(0,0) and A (4,6)

We can use the distance formula to find this;

D = √(x2-x1)^2 + (y2-y1)^2

D = √(4-0)^2 + (6-0)^2

D = √(16 + 36)

D = √52

So the distance between the two points is √52 units

Answer:

[tex]E=3.97\times 10^{-27}\ \text{ergs}[/tex]

Step-by-step explanation:

It is given that,

The sun produces [tex]3.9\times 10^{33}\ \text{ergs}[/tex] of radiant energy per second.

We need to find how many ergs of radiant energy does the sun produce in [tex]1.55\times 10^7\ s[/tex].

Energy produced in 1 seconds = [tex]\dfrac{1}{3.9\times 10^{33}}\ \text{ergs}[/tex]

In [tex]1.55\times 10^7\ s[/tex], energy produced is :

[tex]E=\dfrac{1}{3.9\times 10^{33}}\times 1.55\times 10^7\ \text{ergs}\\\\=3.97\times 10^{-27}\ \text{ergs}[/tex]

Hence, the radiant energy produced in 1 second is [tex]3.97\times 10^{-27}\ \text{ergs}[/tex].

Answer:

Part A: It is given that,

The sun produces 3.9x10^33 ergs of radiant energy per second.

We need to find how many ergs of radiant energy does the sun produce in 1.55 x 10^7 s

Energy produced in 1 seconds =  1/3.9 x 10^33 ergs

In 1.55 x 10^7 s energy produced is : E=3.9/10^33 x 1.55 x 10^7 ergs

= 3.97 x 10^-27 ergs  

In conclusion the radiant energy radiated per second 3.97 x 10^27 ergs

Answer:

y=3/5x-2

Step-by-step explanation:

The slope is already given, 3/5 so just plug it in to the base formula y=mx+b

And the coordinate (0,-2) is your y-intercept. So plug in -2 to b

Therefore y=3/5x-2

Answer:the line would be going down because - 5/3 is negative

Step-by-step explanation:the line would have a slope of - 5/3 so 5 down 3 right

Answer:$20

Step-by-step explanation:

16 divided by 10 = 1.6 (10%)

1.6 times 2 = 3.2 (20%)

16 + 3.2 = 19.2

1.6 divided by 2 = 0.8 (5%)

The complete question is this;

What equation represents a line which is perpendicular to x=0?

1. y = 7

2. x = 4

3. y = x + 1

4. x = 3y

Answer:

y = 7x - 7

Step-by-step explanation:

1st we can look at the meaning of a slope intercept equation

y = mx = b

m = the slope

b = the y-intercept

now when looking at your equation you can plug in your numbers.

y = 7x - 7 is your final answer

What is Congruency

Triangles that are identical in size and shape are said to be congruent triangles. Inferred from this is that the matching sides and angles are equal. Without checking each of the triangles' sides and angles, we can determine whether the two triangles are congruent.

Rule of Congruency:

1- SAS (Side-Angle-Side): Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of the other triangle.

2- ASA (Angle-Side-Angle): Two triangles are congruent if two triangles and the included side of one triangle are equal to two angles and the included side of the other triangle.

3- AAS (Angle-Angle-Side): Two triangles are congruent if any two pairs of angles and one pair of corresponding sides are equal.

4- SSS (Side-Side-Side): If three sides of one triangle are equal to the three sides of another triangle, then the two triangles are congruent.

5- RHS (Right angle- Hypotenuse-Side): If in two right triangles the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the two triangles are congruent.

Since JK= QP
KL= KR
Angle LKJ= Angle QRP

So Δ LKJ ≅ Δ QRP.

Answer:

75 percent

Step-by-step explanation:

12 divided by 4 is 3 and three 3s is 75 percent (I know thats confusing but trust me)

The percentage of shots he make is 75%

The percentage of a number represents a portion or fraction of the whole number expressed as a fraction of 100. It is often used to describe a proportion or rate out of 100.

To calculate the percentage of a number, you typically multiply the number by the desired percentage as a decimal or fraction. The result represents the portion or fraction of the number expressed as a percentage.

The formula for calculating the percentage of a number is:

Percentage = (Number * Percentage Value) / 100.

Substituting the values into the formula above;

percentage = (9 / 12) * 100

percentage = (3/4) * 100

percentage = 0.75 * 100

Percentage = 75%

Answer: 4 plants.

Step-by-step explanation:

In the case that these measurements are of length, the plant being 2.5 yards and the total length of the garden area being 10 yards, the most simple way to solve this is to find how many 2.5 yard sections of this garden are in the given plot.

[tex]10/2.5 =4[/tex]

When 10 is divided by 2.5 you receive the answer "4". You can fit 4 plants within the garden. 2.5 x 2 is 5, and 5 x 2 is 10. 2 x 2, therefore, would give you the answer 4.

Step-by-step explanation:

The required inequality would be 5k < 60 which represents the product of 5, and the number K is less than 60.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

To determine the product of 5 and a number K is less than 60

Here the word "Product"  represents multiplication,

So the product of 5 and a number K would be 5×K = 5K

As per the given condition,

So the required inequality would be 5k < 60

Therefore, the required inequality would be 5k < 60 which represents the product of 5, and the number K is less than 60.
