Answer:top one is a

second one is c

nuber 3 is c

4 is b

Step-by-step explanation:

Answer:

1. x >= 4

2. x /= -4

3. The first one

4. The second one

Step-by-step explanation:

1. Since the bolded arrow is pointing to numbers greater than 4, we can tell that x is greater than 4. The dot on the number 4 is colored, meaning that four is included, thus x is greater than or equal to 4.

2. Since the bolded areas are on every point on the graph except -4, we can tell that x is every number but -4, thus x is not equal to -4.

3. The sign "<" indicates that x is less than 3. This eliminates the second option. Since there is no equal to sign, the dot isn't colored, thus, the first one.

4. The sign "<=" indicates that x is less than or equal to -1, eliminating the third option. Since it is equal to, the dot should be colored, thus, the second one.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Now,

1) 1.23/[tex]10^1[/tex]=0.123

Here LHS=RHS

2) 123/100=1.23

Here LHS=RHS

⇒ 0.123/10 = 0.0123

So, LHS≠RHS

5) 1230/10³=1.23

⇒ 1230/1000

= 1.23

Here LHS=RHS

Answer:The lengths of AB and EF are 10 and 2 respectively

If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;

AB/DE = BC/EF

5x/4 = 5/x

5x² = 20

x² = 20/5

x² = 4

x = 2

Since the value of x is 2, length of AB is 5x = 5(2) = 10

Since EF = x, hence EF = 2

The lengths of AB and EF are 10 and 2 respectively

Step-by-step explanation:

Step-by-step explanation:

abcd = wxyz

ad/dc=wz/yz

12/3=4

56/yz=4

yz=14

Answer is YZ = 14

Step by step

First we know ABCD ~ WXYZ
So we know AD ~ WZ and CD ~ YZ

AD = 12
DC = 3
WZ = 56
YZ = Number (N)

We know sides

3/12 = N/56

Cross multiply

12N= 168

N = 14
Your unknown number of YZ = 14

The graph shows the number of quarts picked and the amount of money the customer paid.


Another customer pays $8.75 for the strawberries she picks. What point (n, a) on the graph represents this?

Answers

Answer:

The point would be (2.5,8.75)

Because we know the customer paid $8.75, we use the y-axis to find this point. Then we'll find where the line meets 8.75 on the y-axis. This is at 2.5. We know that points are in the order of (x,y) therefore the point is (2.5,8.75)

this is more or less of how your graph should look like, based off of the price ($8.75), your y-axis should go up to 8.75 or 8 3/4 and the x axis meets at around 2 1/2

Answers

Multiple the principal amount by the interest rate and the time

Answer:You just divide the original amount by 100 (move the decimal point over two places)

750 / 100 = 7.5

Now you multiply that by the interest rate, which in this case is 7.

7.5 x 7 = 52.5

Now finally, you multiply that by the amount of years. In this case, 3.

52.5 x 3 = 157.5

That would be the amount added after three years! Remember, this is simple interest. Compound interest is a little more complex.

Because we’re given 4 Ws and told that they add to 20, we can simply divide 20 by 4 to find that each W value is equal to 5 (5+5+5+5=20).
We can then use our new found information for w+w+x+x = 24. We know that W = 5, so: 5+5+x+x = 24, and then 10+2x (because there were two Xs (if it was x+x+x, it would be 3x)) so, 10+2x=24, we can subtract 10 from both sides to get 2x by itself:
2x=24-10,
2x=14,
Then to get X by itself, we can divide by 2 on both sides:
2x/2 = 14/2
x=7
So now we know X’s value, X=7

For this equation the easiest thing to start with ratios:

16:4 (scale of 4 due to 4 x 4 being = to 16)

For the y-2 to find y you first will put 8/4 (your scaling back), so 2 so 4-2 would be 2 which makes that equal to y.

Knowing that 8 is the size on the one side these are equal on the top so x-3 had to equal 8, so 11-3=8 so...

x=11

y=2

Find the slope of the line given its graph.

Answers

Slope = Rise/Run
Using the two points, rise (y) = 4 and run (x) = 2, so the slope is 2.

You can also use the slope formula:
(Y2 - Y1)/(X2 - X1)
Rise over run so it’s 4 over 2 the 4 is the rise (y)
And the 2 is the run (x)
You can simplify 4/2 with 2 so you just divide 4 divided by 2 which is 2
Then 2 divided by 2 is 1

Which then gives you 2/1 which is just 2
So the answer is 2

Jane is saving money to buy a game. The game costs $20, and so far she has saved four-fifths of this cost. How much money has Jane saved?

Answer:

To do this problem you need to first find out how much 1/5th of 20 is. Which we can do by multiplying 20 x 1/5 which will give us 4. Since $4 is 1/5 of the total amount and we need 4/5th this value, we can multiply 4 x 4 to get $16 saved in total.
