Hey there!

<h2>ANSWER: $10$ </h2><h2>EXPLANATION:</h2>

If you want to know how to solve, you will need to find the value of x and y. x is equal to 6 and b is equal to 4.

$x(6)+b(4)=?$

So we basically just add 6 and 4.

$6+4=10\\x+b=10(Answer)$

Hope this helps!

A chef uses a circular pan with a 24-inch diameter to make a pizza. What is the area of pizza

RUDIKE [14]

Answer:

The area of a pizza made in that circular pan is 452.39 inches²

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Diameter of the circular pan = 24 inches

Radius of the circular pan = 24/2 = 12 inches

2. What is the area of the pizza?

Let's use the formula of the area of a circle, this way:

Area = π * r²

Substituting with the real values, we have:

Area = 3.1416 * 12²

Area = 452.39 inches²

The area of a pizza made in that circular pan is 452.39 inches²

Terms/Coefficients
Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

x - 2y = 12

5x + 3y = -44

Step 2: Rewrite Systems

x - 2y = 12

[Multiplication Property of Equality] Multiply everything by -5: -5x + 10y = -60

Step 3: Redefine Systems

-5x + 10y = -60

5x + 3y = -44

Step 4: Solve for y

Elimination

Combine 2 equations: 13y = -104
[Division Property of Equality] Divide 13 on both sides: y = -8

Step 5: Solve for x

Define original equation: x - 2y = 12
Substitute in y: x - 2(-8) = 12
Multiply: x + 16 = 12
[Subtraction Property of Equality] Subtract 16 on both sides: x = -4

Please helllppppp........

Debora [2.8K]

8% lower means the gauge is showing 92% of the original pressure

( 100% - 8% = 92%)

Divide the pressure the gauge is showing by 92%

33.58 / 0.92 = 36.5

The actual pressure is 36.5

Solve the equation 3x+x²=-7. Does the number of solutions match the information provided by the discriminant? Explain

MA_775_DIABLO [31]

Answer:

$-\frac{3}{2}+\frac{\sqrt{19}i}{2}$ and $-\frac{3}{2}-\frac{\sqrt{19}i}{2}$

Step-by-step explanation:

$3x+x^2=-7\\\Rightarrow x^2+3x+7=0$

Discriminant

$D=b^2-4ac\\\Rightarrow D=3^2-4\times 7\times 1\\\Rightarrow D=-19$

If the discriminant is a negative number then the roots of the equation are imaginary

$x=\frac{-b\pm \sqrtD}{2a}\\\Rightarrow x=\frac{-3\pm \sqrt{-19}}{2\times 1}\\\Rightarrow x=-\frac{3}{2}\pm \frac{\sqrt{19}i}{2}\\\Rightarrow x=-\frac{3}{2}+\frac{\sqrt{19}i}{2}, x=-\frac{3}{2}-\frac{\sqrt{19}i}{2}$

So, the two solutions are $-\frac{3}{2}+\frac{\sqrt{19}i}{2}$ and $-\frac{3}{2}-\frac{\sqrt{19}i}{2}$

A department store wants to know what motivated customers to visit their store on that particular day. Since 80

Artemon [7]

Answer:

sample.

Step-by-step explanation:

It is given that a department store wants to know what motivated customers to visit their store on that particular day.

We need to fill the blank.

Since 80 percent of the customers are male, researchers have decided to collect a ____ by ensuring that 8 out of every 10 survey participants are male.

For survey, researchers need small part of whole data, i.e., sample.

So, the required answer is "sample".

Since 80 percent of the customers are male, researchers have decided to collect a sample by ensuring that 8 out of every 10 survey participants are male.
