Answer:

Move the decimal two places to the right and add a percent sign.

Step-by-step explanation:

.15= 15%

1.25= 125%

.06= 6.0, or 6%

Answer:

To convert a percent to a decimal, we move the decimal point 2 places to the left, just as we did when we were dividing by 100.

Answer:

F and B (as far as I can see).

Step-by-step explanation:

First, let's simplify the equation. You can easily do this by dividing by -4.

                                                  -4x < 20

                                                   /-4    /-4

                                                      x > -5

REMEMBER- Whenever dividing or multiplying a negative number with inequalities, the sign flips!!

On A, we can see that it has a negative symbol, but if we were to divide that, the sign would flip, making -5 greater than x. That's not what we want.

On B, the 20 is negative instead of the 4. Does this change anything?

                                                   4x > -20

                                                   /4    /4

                                                      x > -5

Nope! It still simplifies to what we had at the beginning so it works!

C and D are slightly confusing me because, well, I don't really see how it's relevant to anything so... It doesn't even have a inequality symbol so I don't know lol.

E is wrong because we need the 5 to be positive.

F is obviously right compared to our first answer.

Answer:

74940

Step-by-step explanation:

I believe you meant 74.94*10^3.  The ^ indicates exponentiation.  10^3 is equivalent to 1000; Multiplying 74.94 by 1000; we get 74940.

angle p=60

Step-by-step explanation:

for bob;

his grades = 2, 2, 2, 2, 2, 10, 10, 10, 10, 10.

total = 60

mean = total/n

= 60/10 = 6

meadian is the middle value in the set of scores. the numbers are even so =

2+10 / 2

median = 12/2 = 6

standard deviation using excel = 4.216

for tom

7, 7, 7, 7, 7, 7, 7, 7, 7, 7

total = 70

mean = 70/10 = 7

median = 7+7/2 = 14/2 = 7

standard deviation using excel = 0

for pat:

1, 1, 8, 8, 8, 8, 8, 8, 10, 10

total = 70

mean = 70/10 = 7

median   =  8+8/2 = 16/2 = 8

Answer:

  5) 112°

  6) 40°

Step-by-step explanation:

5) The angle E or ? is half the sum of the intercepted arcs:

  ? = (130° +94°)/2 = 112°

__

6) The angle D is half the difference of the intercepted arcs:

  ? = (135° -55°)/2 = 40°

Answer:

Price after sale = $52.5

Amount saved = $22.5

Step-by-step explanation:

Cost of Jacket - $75

Percentage off = 30%

Discount price = 30% of $75

Discount price = 0.3 * 75

Discount price = $22.5

Price after sale = Original cost - Discount price

Price after sale = 75-22.5

Price after sale = $52.5

The amount saved = 75 - 52.5

The amount saved = $22.5

Step-by-step explanation:

The dimension of the box is 12 by 7 by 8

The volume of the box = lwh

Given the following

l = w

w = w - 5

h = w - 4

Hence;

w(w-5)(w-4) = 56w

Expand to have

(w^2-5w)(w-4) = 56w
w^3 - 4w^2 - 5w^2 + 20w = 56w
w^3 -9w^2 - 36w = 0

Factorize to get the value of w;

w(w^2-9w-36)=0

w^2 - 12w + 3w - 36 = 0

w(w-12) + 3(w-12)= 0
w = -3 and 12

Hence the dimension of the box is 12 by 7 by 8

The area of a triangle is 1/2 x base x height.

When you know the base and the height of a triangle, multiply them together, than multiply by 1/2 ( this is the same as dividing it by 2).

Answer:

Base times height divided by 2 = area.

Answer:

3/12

Step-by-step explanation:

10-7 is 3, so its 3/12.

The sine function is:

f(x) = -2*sin(x/2) + 3.

So you got it almost correctly, you only forgot to apply the reflection.

We start with the general sine function:

[tex]a*g(w*x + p) +m[/tex]

where g(x) = sin(x)

f(0) = 2*sin(w*0 + p) + 3 = 3

      = 2*sin(p) + 3 = 3

Then we must have p = 0, so there is no phase shift.

We also know that we have a reflection over the x-axis of the parent sine function, we would actually have:

f(x) = 2*-sin(wx) + 3

Finally, to get the value of k we know that the period of the general sine function is 2*pi, while here is 4*pi, then we must have w = 1/2 to get the correspondent correction, so the function is:

f(x) = -2*sin(x/2) + 3.

This is almost the same thing that you got in the graph, where you only forgot to apply the reflection over the x-axis of the parent function.

I know this is a year late, but I took this test it was quite challenging so here is my answer for you I took a picture of the graph because it's hard to graph without any reference pictures

hope this helps

Answer:

We have to use heron’s formula to find the area of the triangle.   Here a=7cm, b=9cm and c=12cm  s = (a+b+c)/2 = (7+9+12)/2 = 28/2 = 14  Area of the triangle = √s(s-a)(s-b)(s-c)  = √14(14-7)(14-9)(14-12) = √14×7×5×2 = √2×7×7×5×2 = √5×(2×2)×(7×7) = 14√5 cm^2  Hence area Of the triangle is 14√5 cm^2.

Step-by-step explanation:

I'm unsure what you want me to do here, so I drew a graph (using Desmos) and the slope.

The slope is given, 5/3. The slope-intercept equation is usually y = mx + b -- m being the slope and b being the y-intercept.

Hi!

Let's check if the equation that we're going to work with is in slope-intercept form.

Remember, the slope-intercept formula is:

                                   [tex]\diamondsuit~~~\boldsymbol{y=mx+b}[/tex]

Where:
