Answers

Answer and Step-by-step explanation:

Given that if a polygon is a square, then a polygon is a quadrilateral, we find the converse, inverse and contrapositive of this implicational statement. The hypothesis is the causative statement and the conclusion is the resultant effect

The converse of this statement is the reverse of its statements hence:

If a polygon is a quadrilateral then a polygon is a square

The inverse of this statement is the negation of the statements hence :

If a polygon is not a square then a polygon is not a quadrilateral

The contrapositive of the statement is the interchange of the hypothesis and conclusion of the inverse statement hence:

If a polygon is not a quadrilateral then a polygon is not a square

A distrubutor wants to make 1,000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is 20% raisins. How many pounds of each should he use?

Answers

Answer:

He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins

Step-by-step explanation:

System of Equations

Let's call

x = pounds of trail mix 5% raisins

y = pounds of trail mix 20% raisins

The distributor wants to make 1,000 pounds of trail mix, thus:

x + y = 1,000     [1]

The mix must be 8% raisings as a combination of x and y, thus:

5x + 20y = 8*1,000 = 8,000

Dividing by 5:

x + 4y = 1,600     [2]

Subtracting [2] and [1]:

4y - y = 1,600 - 1,000

Operating:

3y = 600

y = 200

From [1]

x = 1,000 - y = 1,000 - 200

x = 800

He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins

Answer:

5% raisin mix: 800 lbs

20% raisin mix: 200 lbs

Step-by-step explanation:

Let number of 5% be x; and number of 20% be a.

x + y = 1000

5% · x + 20% · y = 8% of 1000 pounds

0.05x + 0.2y = 80

x = 1000 - y

0.05(1000 - y) + 0.2y = 80

50 - 0.05y + 0.2y = 80

0.15y = 30

y = 200

x = 1000 - y

x = 1000 - 200

x = 800

what two numbers multiply to -36 and add up to 5

Answers

Answer:

9 and -4

Step-by-step explanation:

Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.

First, test if they multiply to -36:

9(-4)

= -36

Then, check if they add up to 5:

9 + (-4)

= 5

So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5

SLOPE HELP

hey, this just help if you're confused about slopes because I've seen a few questions about them I'll clear up a few things!
slope formula is y2-y1/x2-x1
memorize that and you'll be able to find your slope!
if you're given 2 points please label them (3,4) (0,6) labeling is this >>> (x1 3, y1, 4)
(x2 0, y2 6)
this makes it so it's organized and you know what you're subtracting
trust me I'll try to do it in my head and calculate it with a calculator then forget what points I used so WRITE IT DOWN! lol
if you hear parallel it's the same slope!
if you hear perpendicular it's the negative reciprocal example: 3/4x the perpendicular slope would be -4/3x
if you have a point and a slope and a line plugin the point to your line! let's say this one is parallel so the same slope
(3,4) y=3/4x + 2
4=3/4(3)+b
and solve for b!
anyways hopes this helps-

An airplane travels at a constant speed of 320 miles per hour. How far, in miles, will the airplane travel in 15 minutes?

Answers

Answer:

80 miles.

Step-by-step explanation:

If it is traveling at 320 miles per hour, and its asking how much its traveled in 15 minutes you do this:

Since 15 minutes is 1/4 of an hour, you take 1/4 of how fast they are traveling at mph, which in this case is 320 mph.

320/4=80

The airplane will travel 80 miles in 15 minutes.

What is Distance?

The length along a line or line segment between two points on the line or line segment.

we need to use the formula of distance.

distance = speed × time

Since the speed of the airplane is 320 miles per hour, we need to convert 15 minutes to hours:

15 minutes = 15/60 = 0.25 hours

Now we can substitute the values into the formula:

distance = speed × time

distance = 320 × 0.25

distance = 80

Therefore, the airplane will travel 80 miles in 15 minutes.
