An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The weight of the walnuts alone is 360 pounds

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 2x + 3 = 4 is an equation.

We have,

Number of craters of walnuts = 10

Weight of 10 craters of walnuts = 370 pounds

Weight of empty crate = 10 pounds

Weight of the 10 walnuts = M

Weight of the 10 walnuts + weight of the crater = 370 pounds

This can be written as an equation:

M + 10 = 370

Subtract 10 on both sides.

M = 370 - 10

M = 360 pounds

Thus,

The weight of the walnuts alone is 360 pounds

To solve percent problems, you can use the formula        part            %

                                                                                              -------    =    -----

Answer:

The answer to this is C. The dinosaur is about 5 feet taller than the person.  

Step-by-step explanation:

The reason why is because the human is 4 feet since it says that 1/2 inch on the scale is 2 feet and the human is 1 inch on the scale so the human is 4 feet.  

The dino is 8 feet since it goes to 2 inches on the scale which means 8 feet. The difference between 4 and 8 is 4, so 5 feet is the approximate for this problem.

Answer:

(0,inf)

Step-by-step explanation:

The range is the y-values included in the graph. This function is exponential decay, which means it has a horizontal asymptote. A function will never cross or touch the horizontal asymptote. Since the asymptote for this graph is y=0, the lowest y-value will be 0, however it is not an included value. Then, the graph will reach every y-value above 0, so the highest range will be infinity.

Answer:

i = 87

Step-by-step explanation:

First, you would distribute 5 through the parenthesis by multiplying everything inside by 5. So 5*21=105 and 5*4=20. Next, you would add them together and simplify the equation to 125 - i = 38. Then you would subtract 38 from 125 to receive the equation 87 - i = 0. Finally, you would add i to both sides and get i = 87.

20 percent * 180 =

(20:100)* 180 =

(20* 180):100 =

3600:100 = 36

Now we have: 20 percent of 180 = 36

Question: What is 20 percent of 180?

Percentage solution with steps:

Step 1: Our output value is 180.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$180=100\%$.

Step 4: Similarly, $x=20\%$.

Step 5: This results in a pair of simple equations:

$180=100\%(1)$.

$x=20\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{180}{x}=\frac{100\%}{20\%}$

Step 7: Again, the reciprocal of both sides gives

Decreasing: y, infinity

Constant: y, negative infinity

Step-by-step explanation:

You just had it backwards, the interval for infinity is based on the x-axis not the y-axis. The decreasing portion is moving toward positive infinity on the x-axis because it's moving to the right. The constant is moving to the left so it is negative infinity.

Step-by-step explanation:

9x+4+2x=180

= 11x=176

= x=176/11

=x=16

2x=32°

9x+4=148°

The measure of two angles are 2x=31.6° and (9x+4)°=146.4°.

From the given figure, there are two angles 2x° and (9x+4)°.

Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.

Here,

2x°+(9x+4)°=180° (Sum of two adjacent angles is 180°)

⇒ 11x+4=180

⇒ 11x=174

⇒ x=174/11

⇒ x=15.8°

So, 2x=31.6° and (9x+4)°=146.4°

Therefore, the measure of two angles are 2x=31.6° and (9x+4)°=146.4°.
