The cube volume is 1000cm find the all face area
A. 200cm
B. 300cm
C. 500cm
D. 600cm

Answers

Answer:

D. 600 [tex]cm^{2}[/tex]

Step-by-step explanation:

Volume of a cube = [tex]s^{3}[/tex] = 1000, s = [tex]\sqrt[3]{1000} =10[/tex]

So, the side length is 10 cm

Surface area of a cube is 6[tex]s^{2}[/tex] where s is the side length

so [tex]s^{2}[/tex] = [tex]10cm^{2} = 100 cm^2[/tex]

6*100[tex]cm^{2}[/tex] = 600 [tex]cm^{2}[/tex]

So the answer is D. 600 cm (it should have a little superscript 2 next to it)

area= D. 600cm (centimeters)

2.646 for the leg.

2(3x – 5) = 8
what is the x?

Answers

Answer:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2*(3*x-5)-(8)=0

2 • (3x - 5) -  8  = 0

Pull out like factors :

6x - 18  =   6 • (x - 3)

6 • (x - 3)  = 0

Solve :    6   =  0

Add  3  to both sides of the equation :  

x = 3

Answer: x = 3

Step-by-step explanation:

2(3x-5)=8

first, you multiply 2 by 3x and -5.

6x-10=8

since we want 6x by it’s self we add 10 to its self and add it to 8 as well.

6x = 18

now we divide 6 to both 6x and 18.

x = 3

Answers

Answer:

Step-by-step explanation:

36 / 3 = 12

12 = 4 x 3

V = L x W x H

= 4ft x 3ft x 3ft

Can someone help me i really needed

Answers

The answer would be the third option or C

Answer:

C: √74

Step-by-step explanation:

We have to use the Pythagorean theorem to answer this (a² + b² + c²). We have a and b so all we have to do is square 5 and 7 (a and b) so we get a² b², then we add this to get c² as stated by the Pythagorean theorem. So, 7² (7 x 7) is 49, and 5² (5 x 5) is 25. 25+49 (a² + b²) is 74 (c²). So the square root of this would be the absolute length of the hypotenuse because this is the hypotenuse squared. Meaning that the answer would be √74 (square root of 74)

Taylor emptied out her change jar to buy a new soccer ball for practice. The jar contained 128 coins consisting of quarters and dimes that totaled $25.10. Which system of equations could be used to determine how many quarters, q, and how many dimes, d, Taylor had in her change jar?

Answers

Answer:

.25q+.10d=25.10

q+d=128

Step-by-step explanation:

Since a quarter is 25 cents and a dime is 10 cents that is how you figure out your first equation. You set it equal to 25.10 because that is the amount of money it totals to. The second equation (q+d=128) is used because the amount of quarters plus dimes needs to make 128.

Let q be the no. of quarters and d be the no. of dimes.

q+d=128
25q+10d=2510

These are the system of equations. To solve it, we do this:

q=128-d
25(128-d)+10d=2510
3200-25d+10d=2510
15d=690
d=46
q=128-46=82

Which subject is this?

please help and show work please​

Answers

Answer:

see below

Step-by-step explanation:

a. -11r ≥ 220

Divide both sides by -11 to isolate r.

r ≥ -20

b.

-8 ≤ -7 + (x/10)

Add 7 to both sides.

-1 ≤ x/10

Multiply both sides by 10 to cancel out the denominator of x.

-10 ≤ x

c. -1 - 6(5q - 2) ≥ -139

Distribute the -6 across the parentheses.

-1 - 30q + 12 ≥ -139

Combine like terms on the left side.

-30q + 11 ≥ -139

Subtract 11 from both sides.

-30q ≥ -150

Divide both sides by -30 to isolate q.

q ≥ 5

Hope this helps!

-11r>=220

divide both sides by -11
since both sides are divided, flip the sign

r<=-20
r is less than or equal to negative twenty

All real solutions

All solutions that lie on f(x)

All positive solutions

All whole number solutions

pls answer fast!

Answers

Answer:

C. All positive solutions

Step-by-step explanation:

We can see that the solutions (or points that intercept the x-axis) are at 0,1 and 0,2. We can simplify this to just 1,2 if you would like, but nevertheless all x-intercepts are positive.

x = 1 and x = 2 are the solutions of the parabola shown.

All whole number and positive solutions.

Options C and D are correct.

How do you find the opening of a parabola?

There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

When we are looking for a solution to a graphical function f(x), we basically mean the x-intercepts of the graph.

The place where the graph cuts/crosses the x-axis are the solutions of the graph. The y point will always be 0 at those designated x values.

Looking at the graph, we see that:

x = 1 and x = 2

are the solutions of the parabola shown.

All whole number and positive solutions.

Options C and D are correct.

After class she noticedthat some of the students were avoiding eye contact. When the class met next, she felt the need to explain herself: "I mean, hip-hop isjust like pop music.

What is the area of this problem below An acid-base indicator is usually a weak acid with a characteristic color in the protonated (acid) and deprotonated (conjugate base) forms. In this assignment, you will monitor the color of an acetic acid solution containing Bromocresol Green as an indicator, as the pH is changed and then you will use your data to calculate the ionization constant, Ka, for the bromocresol green indicator and compare to an accepted value.1. Start Virtual Chemlab, select Acid-Base Chemistry, and then select lonization Constants of Weak Acids from the list of assignments. The lab will open in the Titration laboratory. Bottles of 0.1104 M NaOH and 0.1031 M HAC (acetic acid) will be on the lab bench. The buret will be filled with the NaOH solution and a beaker containing 10.00 mL of the HAc solution will be on the stir plate. The stir plate will be on, Bromocresol Green indicator will have been added to the beaker, and a calibrated pH probe will also be in the beaker so the pH of the solution can be monitored. 2. What is the color and pH of the solution? 3. On the buret, the horizontal position of the orange handle is off for the stopcock. Open the stopcock by pulling down on the orange handle. The vertical position delivers solution the fastest with three intermediate rates in between (slow dropwise, fast dropwise, and slow stream). Turn the stopcock to the second position or fast drop-wise addition. Observe the color of the solution and close the stopcock when you observe the change in color by double clicking on the center of the stopcock. 4. What is the color and pH of the solution now? 5. Continue to add NaOH as before or at a faster rate. What is the final color and pH of the solution after all of the NaOH is added? 6. An acid-base indicator is usually a weak acid with a characteristic color in the protonated and deprotonated forms. Because bromocresol green is an acid, it is convenient to represent its rather complex formula as HBOG. HBOG ionizes in water according to the following equation: HBOG + H2O = BCG + H3O+ (yellow) (blue) The K. (the equilibrium constant for the acid) expression is: Ka = [BCG-][H3O+]/[HBCG) When [BCG-[ = [HBCG), then Ka = [H3O+). If you know the pH of the solution, then the [H3O+] and Ka can be determined. What would be the color of the solution if there were equal concentrations of HBCG and BCG-? What is the pH at the first appearance of this color? What is an estimate for the Ka for bromocresol green?
