Answer:

8 correct.

Step-by-step explanation:

80 / 100 = x / 40    (Since he got 80% INCORRECT you will subtract the value of x from 40)

100x = 80 x 40

x = 3200 / 100

x = 32

40 - 32 = 8

Answer:C

Step-by-step explanation:

The derivation of the quadratic function is true

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

ax² + bx + c = 0

Step 1 :

ax² + bx + c = 0

Step 2 : Subtracting c on both sides , we get

ax² + bx = -c

Step 3 : Divide by x on both sides , we get

ax + b = -c/x

Hence , the steps are true in solving the quadratic equation

Answer:

She spent $5.05 for her total purchase.

Step-by-step explanation:

First, you should convert the fractions into decimals to make it easier, which would make it, 1.5, .25, 1.

Second, multiply 1.5 by 2 because there are 1.5 pounds which are payed for $2.00. Do the others fractions corresponding with the number of pounds and the cost this same way. 1.5 multiplied by 2 is 3. .25 multiplied by 1.60 is 0.4, 1 multiplied by 1.65 is 1.65.

Lastly, Add it all up, 3+0.4+1.65=5.05

Step-by-step explanation:

Answer:

x = 81

Step-by-step explanation:

x + 24 = 105

Subtract 24 from both sides

x = 81

Simple.

The value of x is 81.

If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.

Given:

<1 = x

<2 = 24

exterior angle = 105

Now, using exterior angle property

105 = x +24

x= 105 - 24

x= 81

Hence, the value of x is 81

Given:

Number of  blue marbles, twice as many red marbles as blue, and 8 yellow marbles.

She has a total of 32 marbles.

To find:

The number of red marbles.

Solution:

Let number of blue marbles be x.

Then, number of red marbles = 2x

Number of yellow marbles = 8

Total number of marbles = 32

[tex]x+2x+8=32[/tex]

[tex]3x=32-8[/tex]

[tex]3x=24[/tex]

[tex]x=8[/tex]

Now,

Number of red marbles [tex]=2(8)=16[/tex]

Therefore, there are 16 red marbles.

If x equals 3 then y must equal 1.2

Answer: y=6

-4(3)+5y=18

-12+5y=18

add 12 to both sides

-12+5y+12=18+12

5y=18+12

5y=30

divide both sides by 5

5y÷5=30÷5

y=30÷5

y=6

Answer:

Use synthetic division to solve

Step-by-step explanation:

When dividing a polynomial by a zero, you first want to find the zero to divide by. Solving the zero (x+2) will give us the value of x to divide by. Subtracting 2 from each side gives us x=-2. Then, we write out the full polynomial. Since the only degrees that have numerical values are x^5 and 32, we substitute zero for the values in between (0x^4, 0x^3, 0x^2, and 0x). Then we follow the steps of synthetic division (as seen in the photo) to find our new values for our new equation.

Answer:

9 miles

Step-by-step explanation:

If 1 hour is 12 miles, then 30 mins is 6 miles, then 15 minutes is 3 miles.

30+15=45

6+3=9

The first cyclist bikes 9 miles in 45 minutes.

Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:

Therefore, the first cyclist bikes 9 miles in 45 minutes.

A. 83

We can see that the Y value is less than 90 degrees or right angle. So we can cross out answer options C and D.

And we should know that all of the triangles add up to 180 degrees.

So the math would do is:

46+51=97

180-97=83

So...

The Y value is 83.

Answer: its either a or b

Error is the difference between the actual length of an object and its measured length.

The closest to the percent error for Diego's measurement is 4.3%

Error = Actual length - Measured length

= 23cm - 22cm

= 1 cm

Formula = Error/ Actual length × 100

= 1 /23 × 10

= 4.35%

Therefore, the closest to the percent error for Diego's measurement is 4.3%
