The product of the roots of 2x^2 - 7x + N = 0 is -5. Find N.

Answer:

Aluminum

Step-by-step explanation:

To find the unit rate being used for the substance, we need to divide the grams by the cubic measurement. ([tex]g[/tex]/[tex]cm^{3}[/tex]).

108 grams divided by 40 is 2.7, which is the density of Aluminum, therefore making Aluminum the answer.

Answer:

$18 hun :)

Step-by-step explanation:

Answer:

18$

Step-by-step explanation:

Answer:

The correct answer is B.

Lets go through explaination:

According to the question, the answer should be between 2/5 and 7/8

If we changed the fraction into decimal, we will get 2/5 as 0.4 and 7/8 as 0.875

So now, we have to get the numbers in between 0.4 and 0.875

Changing all the fraction in the form of decimal:

In the above answers, only no. B is between 2/5 and 7/8.

So, B is the correct answer.

Answer:

[tex]a=7.5[/tex]

Step-by-step explanation:

Given the function [tex]f(x)=6x-15[/tex] and the output [tex]30[/tex] when [tex]x=a[/tex], we can write the equation:

[tex]6a-15=30[/tex]

[tex]6a=45[/tex]

[tex]a=7.5[/tex]

We can insert the value of [tex]a[/tex] into the function to verify the output equals [tex]30[/tex]:

[tex]f(a) = 6a-15[/tex]

[tex]= 6(7.5)-15[/tex]

[tex]=30[/tex]

∴ We have verified that [tex]a=7.5[/tex]

Hope this helps :)

Answer:

(A). x ≥ [tex]\frac{16}{5}[/tex] and x ≤ - [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

5x - 4 ≥ 12 ⇔ 5x ≥ 16 ⇒ x ≥ [tex]\frac{16}{5}[/tex]

and

12x + 5 ≤ - 4 ⇔ 12x ≤ - 9 ⇔ 4x ≤ - 3 ⇒ x ≤ - [tex]\frac{3}{4}[/tex]

Answer:so it would be between 14/20

Step-by-step explanation:

Answer:

Step-by-step explanation:

Well first you should rearrange the equation to make it easier to graph. 8x-4y=16.

8x - 4y = 16.

8x +4y = 16 + 4y

8x -16 = 4y

Divide both sides by 4 to get y by itself.

2x - 4 = y

The y-intercept is -8 and the slope is 2x so the graph would look something like this.

Answer: 90°

Step-by-step explanation:

i took the test

The value of angle APA' is 90°.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a point 'p' which is a fixed point.

Triangle ABC is rotated about the 'p' point such that the new location of A, B, and C becomes A', B', and C'.

The new triangle formed is triangle A'B'C'.

From the figure, we can clearly see that the angle APA' is a right-angle triangle.

m∠APA' = 90°

Thus, the value of angle APA' is 90°.

Answer:

720 ways

Step-by-step explanation:

150.7

To solve this, we first turn both the fractions into decimals :

[tex]\frac{1}{5} = 0.2\\[/tex]    (add this to 426 to get 426.2)

[tex]\frac{1}{2} = 0.5[/tex]    (add this to 275 to get 275.5)

Then, just solve the equation :

426.2 - 275.5 = 150.7

To see if it is possible, you will want to create an equation.

3(4x+2) = 6(2x+2)

As you can see, you will need to use the distributive property for this equation.

12x + 6 = 12x + 12

Remove 6 from both sides.

12x = 12x + 6

Divide 12 by both sides

x = x + 0.5

Because the answer wasn't x = x, the two plants won't ever be the same height. Even if you tried to subtract 0.5, you'd only get a negative 0.5 on the other side.

Answer:

28.125 hours

Step-by-step explanation:

Amount of money paid per hour = $8

Bonus of being a manager = $25

Total amount of money paid = $250

To find:

Number of hours worked for this month?

Solution:

Let the number of hours worked = [tex]h[/tex] hours

Amount of money paid for [tex]h[/tex] hours = $8[tex]h[/tex]

As per question statement:

Bonus + Amount of money paid for [tex]h[/tex] hours = $250

[tex]25 + 8h = 250\\\Rightarrow 8h = 250 -25\\\Rightarrow 8h = 225\\\Rightarrow h =\dfrac{225}{8}\\\Rightarrow \bold{h = 28.125\ hours}[/tex]

Therefore, the answer is:

Number of hours worked = 28.125 hours

Answer:

x = 8

Step-by-step explanation:

1/2(4x – 8) + 3x = 36

~Simplify left side

2x - 4 + 3x = 36

~Combine like terms

5x - 4 = 36

~Add 4 to both sides

5x = 40

~Divide 5 to both sides

x = 8

Best of Luck!

the correct answer should be ASA since 2 angles and 1 side is congruent

Answer:

It is C.

Step-by-step explanation:

You divided 6.57 by 3

and 3 by 3

3 by 3 = 1

6.57 = 2.19

B 7feet

Step-by-step explanation:

Side a = 24

Side b = 25

Side c = 7

Angle ∠A = 73.74° = 73°44'23" = 1.287 rad

Angle ∠B = 90° = 1.5708 rad = π/2

Angle ∠C = 16.26° = 16°15'37" = 0.28379 rad

C=16.26°B=90°A=73.74°b=25a=24c=7

Area = 84

Perimeter p = 56

Semiperimeter s = 28

Height ha = 7

Height hb = 6.72

Height hc = 24

Answer:Think x is 3

Step-by-step explanation:

the metal bar/random line is almost the same size as the other two sides of the triangle. if one side is 32ft, then the opposite side is 32ft also. the bottom is 100ft, so we could eliminate C. because it couldnt be that number. now the bottom triangle, one side is 40ft so the other side has to be 40ft as well. its asking about the metal bar.

its either:

A. 53.2ft     or

B. 44.4

because the line is almost the same size as 32ft. its almost a equallateral triangle. i would go with A. though because if you imagine the line at the bottom of the line (100ft.) the line would go over half of it (and 53.2 is over half of 100) so i would say

A.53.2

if this didnt help let me know. and i will delete this (if i can-)
