Answer:60

Step-by-step explanation:

Answer:

60

Step-by-step explanation:

Given:

If AB = 0,

Then it is not necessary that A=0 or B=0

To prove this, we consider an example:

Let n=m = p =2

Then AB is given as:

Clearly AB= 0 but A,B not equals to zero.

Hence, the given statement is not true.

Hence, the answer is false.

The money left for Anna is $180 which was earned by babysitting for 15 months.

For the given question;

Monthly saving of Anna is $40.

Total time of babysitting is 1 and 1/4 years.

Total time = 5/4 years = 15 months.

Total money saved = 15 × $40 = $600.

70% of the money is spent

Thus, 30 % money is left.

Find 30% of $600

= 30 × 600/ 100

= $180.

Thus, the money left for Anna is $180 which was earned by babysitting for 15 months.

Since

even degree function, it will have an even number of real zeros, and, since it has a degree of 4, there will be 4, 2 or 0 real zeroes

Answer:

y=-1/2x+1

Step-by-step explanation:

perpendicular is when the gradient of the existing equation is reciprocated (swapped sides and flipped)

new gradient- -1/2

so our new equation is y=-1/2x+c

we have the co-ordinates for x and y so substitute into new equation

1=(-1/2 x 0) + c

so c=1

Hence our equation is : y=-1/2x+1

Nishnat can trade box tops only for printer.

Nishant keeps the box tops in 38 folders.

Each folder contains 80 box tops.

Number of box tops nishant has = number of folders x number of box tops in each folder

Number of box tops nishant has = 38 x 80

Number of box tops nishant has = 3040

For printer, he needs 1500 box tops

1500 < 3040

So, he can trade box tops for a printer.

For digital camera, he needs 3500 box tops

3500 > 3040

So, he can not trade box tops for a digital camera.

For tablet computer, he needs 5000 box tops

5000 > 3040

So, he cannot trade box tops for a tablet computer,

Therefore, Nishnat can trade box tops only for printer.

The cost for the soda is proportional.

For there to be a proportional relationship, there must be a constant.

In this case, one soda costs $2.75.

Also, five sodas cost $13.75. The cost per soda will be:

= $13.75 / 5

= $2.75

Since the values of $2.75 are the same, it has a proportional relationship.

Answer:

x = 23

y = 119

Step-by-step explanation:

Line m is parallel to line n and the angle given as 61 and the angle that is represented with 4x - 31 are alternate angles and have equal measurement.

We can write the following equation based on this information:

4x - 31 = 61 add 31 to both sides

4x = 92 divide both sides by 4

x = 23

now onto y,

the angle represented with y and the angle that is represented with 4x - 31 are supplementary and their measures add up to 180:

4x - 31 + y = 180 replace x with 23

4*23 - 31 + y = 180

92 - 31 + y = 180 subtract like terms

61 + y = 180 subtract 61 from both sides

y = 119

If n represents of nickels in the​ jar, then the equation that can be used to find n is; n + 77 = 90

An equation is an expression that shows the relationship between two or more numbers and variables.

Assume that n represent the number of nickels in the jar.

Given that the jar contains only​ , pennies, nickels,​ dimes, and quarters. There are 28 ​pennies, 26 dimes, and 23 quarters. The rest of the coins are nickels.

This means that the total number if pennies, dimes and quarters would be;

23 + 28 + 26 = 77

This means that the number of coins that are not nickel = is 77

The total number of coins in the jar is 90. Therefore, the equation that can be used to find n is;

n + 77 = 90

n = 90- 77

n = 13 nickels

EXPLANATION

We have that the entry fee is $10 and for each ride, $6 must be paid.

We want to complete the table by finding the cost of 3 rides.

First, let us represent the cost of going to the fair and taking the ride.

Let the number of rides a person takes by x.

We have that the cost of taking x rides will be the entry fee plus the cost of each ride taken:

Cost = 10 + 6x

So, for taking 3 rides, it will cost:

Cost = 10 + 6(3)

Cost = 10 + 18

Cost = $28

That is the cost of taking 3 rides.

The question is: When we're both stock values the same? Then all you have to do is match both equations and solve for x, like this

Answer:

Step-by-step explanation:

You want the number of small (12 oz) cups and large (22 oz) cups sold if 80 total cups and 1460 ounces were sold.

We can let x represent the number of large cups sold. Then 80-x is the number of small cups sold, and the total ounces of lemonade sold are ...

  12(80 -x) +22x = 1460

Simplifying the equation gives ...

  960 +10x = 1460

  10x = 500

  x = 50

Then the number of small cups sold is ...

  80 -x = 80 -50 = 30

30 small cups and 50 large cups were sold.
