To multiply mixed numbers, convert them into improper fractions, multiply the numerators and denominators separately, and simplify the resulting fraction.

Explanation:

To multiply mixed numbers, we first convert them into improper fractions. Then, we multiply the numerators and denominators separately and simplify the resulting fraction if possible.

In this case, (2 4/5) can be written as 14/5 and (-5 2/3) can be written as -17/3. Therefore, (2 4/5) (-5 2/3) can be simplified to (-14/5) * (-17/3).

To multiply fractions, we multiply the numerators and denominators together. So, (-14/5) * (-17/3) = (14 * 17) / (5 * 3) = 238/15 = 15 13/15.

Answer: OPTION C

Step-by-step explanation:

By definition, the roots of the quadratic function are the interceptions of the parabol with the x-axis.

As you can see in the graph, the parabola intersects the x-axis at:

[tex]x=-5\\x=1[/tex]

Then these are the roots.

Therefore, this means that:

[tex]x=-5\\x+5=0\\\\x=1\\x-1=0[/tex]

So, the factorization is the following:

[tex](x+5)(x-1)=0[/tex]

ANSWER

[tex]y = (x + 5)(x - 1)[/tex]

EXPLANATION

From the graph, the x-intercepts are

[tex]x = 1[/tex]

and

[tex]x = - 5[/tex]

This implies that (x-1) and (x+5) are factors of the function represented by the graph.

Therefore we factor the function as

[tex]y = (x + 5)(x - 1)[/tex]

The correct choice is C.

Answer:

Quadratic Formula x = [-b +- Sq root (b^2 - 4ac)] / 2a

In this example a= 2 b= -6 c= 5

x = [- - 6 +- Sq root ((-6^2) - 4 *2*5)] / 2*2

x = [6 +-sq root (36 -40)] / 4

x = 6 +- 2i / 4

x1 = 1.5 + .5i  

x2 = 1.5 -.5i

Step-by-step explanation:

Answer:

x = 1.5 - .5i and 1.5 + .5i

Step-by-step explanation:

to start off - this is the quadractic fromula: x = -b ± √b²-4(a)(c) / 2(a)

a = 2x²

b = -6x

c = 5

now you just fill the numbers in to the formula!!

x = -(-6) ± √(-6)²-4(2)(5) / 2(2)

x = 6 ± √36 - 40 / 4

x = 6 ± √-4 /4

x = 6 ± 2i / 4

x = 6+ 2i/4     and 6 - 2i/4

x = 1.5 + .5i    amd 1.5 - .5i

hope this helps!!

Answer:

125%

Step-by-step explanation:

Lopez made more than the required minimum. So, his percentage will be over 100, for sure. But how much?

This question is essentially asking "60 is what percent of 48"?

We can translate this into:

60 = P * 48

Note: is means "=" and of means "*"

Solving for p:

[tex]60=P*48\\P=\frac{60}{48}\\P=1.25[/tex]

In percentage it is 1.25 * 100 = 125%

Final answer:

Mr. Lopez made 125% of the minimum required number of circuit boards on Wednesday, by dividing the 60 circuit boards he made by the minimum of 48 and then multiplying by 100.

Explanation:

The question asks how to calculate the percentage of the minimum amount of circuit boards Mr. Lopez made on Wednesday. To find this percentage, we divide the number of circuit boards made by Mr. Lopez by the minimum required number and then multiply by 100 to convert it into a percent.

Step-by-Step Solution:

Mr. Lopez made 60 circuit boards on Wednesday.

The minimum requirement is 48 circuit boards per day.

To find the percentage, use the formula: (Actual amount / Minimum requirement) x 100%.

So, the calculation would be: (60 / 48) x 100% = 125%.

Therefore, Mr. Lopez made 125% of the minimum required number of circuit boards on Wednesday.

It's A. 2.5

Final answer:

To find the area of a circle with a circumference of 53.41 inches, calculate the radius using r = C / (2π) and then find the area using A = πr². The area is approximately 226.795 square inches.

Explanation:

To find the area of a circle given its circumference, you can use the formula for the circumference, C = 2πr, where C is the circumference and r is the radius. From there, you can derive the radius and then calculate the area using the formula A = πr². Given that the circumference is 53.41 inches, we first find the radius (r).

The formula for circumference (C) simplifies to r = C / (2π). Thus, r = 53.41 inches / (2×3.14), which gives us r = 53.41 / 6.28 = approximately 8.5 inches. Now that we have the radius, we can plug it into the area formula A = πr². Using the given radius, the area A equals 3.14×8.5² inches², which is about 3.14×72.25 inches² = 226.795 inches² (rounded to three significant figures).

3 x 60 = 180

180 < 300

Answer:

Both because they're basically the same thing ;-;

Step-by-step explanation:

1) 23.33 - 15.59 = 7.29

  7.74/6 = 1.29 So he bought 1 soda ;-;

2) 15.59 + 6c = 23.33 - Subtract 15.59 from both sides:

    6c = 7.74 - Divide both sides by 6

    c = 1.29 So he bought 1 soda again

The rest of the money is probably the tax so ;-;

Good luck and hopefully I helped!

Step-by-step explanation:

Answer:

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Step-by-step explanation:

Using distributive property:

A : -30(3+2w)  =  -90 - 60w          : equivalent to -90 - 60w

B : (-9-6w) ⋅ 10  = -90 - 60w          : equivalent to -90 - 60w

C : -3(30 - 20w)  = -90 + 60w       : NOT equivalent to -90 - 60w

D : (6 + 4w)×15  = 90 + 60w          : NOT equivalent to -90 - 60w

E : −20(4.5 + 3w) = - 90 - 60w     : equivalent to -90 - 60w

Answer:

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Answer:

A, B and E.

Step-by-step explanation:

We have -90-60w. Both 90 and 60 are multiples of 30, so we can apply common factor -30:

-90-60w = -30(3+2w). Then option A is correct.

Now, 90 and 60 are also multiples of 10, so we can apply common factor 10:

-90-60w = 10(-9-6w). Then option B is correct.

Now, 90 and 60 are also multiples of 3, so we can apply common factor -3:

-90-60w = -3(30+20w). Then option C is incorrect.

Now, 90 and 60 are also multiples of 15, so we can apply common factor 15:

-90-60w = 15(-6-4w). Then option D is incorrect.

Now, 90 is not a multiple of 20 but we can apply common factor obtainig a decimal number. Applying common factor -20 we have

-90-60w = -20(4.5+3w). Then option E is correct.

Answer:

The answer is 70.

Step-by-step explanation:

Change the percent into a decimal and divide 21 by it.

Answer:

A

Step-by-step explanation:

This is an even polynomial because both ends end up. This means the degree of the polynomial is even. This means b and c are not solutions since their degrees are odd.

To determine between A and D look at the x-intercepts. The x-intercepts of a polynomial graph have a special relationship with its equation. The x-intercepts are the solutions or roots of the factors. This means that when each factor is set equal to 0 and solved, its solution is an x-intercept. Here the x-intercepts are x = -1, 0,3. This means the factors are x(x+1)(x-3).

Notice at x = -1, the function touches but does not cross? This means the factor has an even exponent on it.

So the expression is likely x(x+1)^2 (x-3).

Since only one factor has an exponent, the answer is A.

Answer:

Reference angle: [tex]\frac{\pi}{2}[/tex]

[tex]tan(\theta)=tan(\frac{3\pi}{2})[/tex] is not defined.

Step-by-step explanation:

The angle [tex]\theta[/tex] goes from the positive x-axis to the negative y-axis.

Therefore the reference angle can be calculated as following:

[tex]\frac{3\pi}{2}-\pi=\frac{\pi}{2}[/tex]

 We know that [tex]tan(\theta)[/tex]is:

[tex]tan(\theta)=\frac{sin(\theta)}{cos(\theta)}[/tex]

If [tex]\theta=\frac{3\pi}{2}[/tex] then [tex]cos(\frac{3\pi}{2})=0[/tex], therefore [tex]tan(\frac{3\pi}{2})[/tex] is not defined, because the division by 0 is not defined.

Answer:

I know for a fact that the reference angle for 3pi/2 is pi/2 so the first one is A, and if I'm not mistaken, the second one should be undefined.

Step-by-step explanation:

I think the answer is 15.

To convert 425 grams of flour to pounds, you can set up a proportion and solve for X. The answer is approximately 1.898 pounds.

To convert grams to pounds, we can use the conversion factor:
1 ounce    1 pound
————- and —————

28.4 grams  16 ounces

To convert 425 grams of flour to pounds, we can set up a proportion:

X pounds    425 grams

16 ounces     28.4 grams

To solve for X, we can cross-multiply and then divide:

X pounds = (425 grams x 16 ounces) / 28.4 grams

Calculating this, we find that X = 1.8978 pounds of flour.

Step-by-step explanation:

Since we have the same amount of each ingredient, the first step is to find out what will be the limiting ingredient (of which we need more quantity per cake) that ingredient is flour.

So the cakes we can make with 75 cups of flour will be the total cakes we can make.

since we need 3 cups of flour per cake:

[tex]\frac{75 cups}{3cups/cake} =25 cakes[/tex]

we can make 25 cakes in total.

*sugar will be left over but because with 25 cakes the flour ends, this is the total amount of cakes we can make,
