Answer:

for negative the  highest number is the least, I believe and for positive numbers the least number is just the one that is the smallest  Step-by-step explanation:

Answer:

For every  7  small prizes won, there were  3  large prizes won.

ratio : 42:18 or 7:3

As 42/18  is the same as 7/3  For every 7 small prizes won, there were 3 large prizes won.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, At a certain game at a school carnival, people won 42 small prizes and 18 large prizes.

Now, 42/18 = 21/9 = 7/3.

∴  For every 7 small prizes won, there were 3 large prizes won.

Answer:

(-6,14)

Step-by-step explanation:

We are given one endpoint and the midpoint, so we have to figure out how far apart these two points are:

(4,12) and (-1,13)

First, we take the x values because these two points are using the (x,y) pattern.

How far away are 4 and -1? The answer is 5.

How far away are 12 and 13? Only 1

If we start at the endpoint (4,12) and go to the midpoint at (-1,13), we go 5 to the left. That means we need to go 5 more spaces to the left to get to the other endpoint. The first part of our answer is -6, which is 5 to the left of -1.

Doing the same thing for the y values now, to get from 12 to 13 we go up 1. So we have to go up one more to find the y value of the other endpoint. If you are at 13 and you go up one, you are at 14.

Answer:

23/99

Step-by-step explanation:

0.23 is x.

Because x is recurring in two decimal places, we will multiply it by 100.

100x=23.23

Then we subtract.

100x-x=23.23-0.23

99x=23

x=23/99

Answer:

Its irrational because pi is a repeating number with no pattern.

Answer:

a) on the way there, the speed = 50 m/hr

b) on the way back home, speed = 30 m/hr

Step-by-step explanation:

[tex]speed (s) = \frac{distance(d)}{time(t)} \\distance = speed\ \times\ time[/tex]

on the way to Disney land:

distance = d

speed = s

time = t = 6 hours

d = s × t

d = s × 6

d = 6s - - - - - (1)

On the way back:

speed decreased by 20m/hr

This means that s₂ = (s - 20)m/hr

time = t₂ = 10 hours

∴ d = s₂ × t₂

d = (s - 20) × 10

d = 10s - 200  - - - - (2)

Note that the distance is the same to and from disney land, therefore, equation (1) equals equation (2)

∴ 6s = 10s - 200

collecting like terms:

10s - 6s = 200

4s = 200

∴ s = 200 ÷ 4

s = 50 m/hr

Therefore on the way there, the car was moving at a apeed of 50m/hr

speed on the way back home (s₂) = (s - 20) m/hr

∴ s₂ = 50 - 20

s₂ = 30 m/hr

Therefore on the way back home the speed was 30 m/hr

Slope formula: y2-y1/x2-x1

Part one:

-7-4/-7-(-7)

-11/0

Since the denominator is 0, the slope is undefined.

Part two:

-9-(-9)/2-(-5)

0/7

Since the numerator is 0, the slope is 0.

Best of Luck!

Problem 1

Use the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (-7 - 4)/(-7 - (-7))

m = (-7 - 4)/(-7 + 7)

m = -11/0

The result is undefined as we cannot divide by zero.

This line is vertical and all vertical lines have undefined slopes. This happens when both points have the same x coordinate.

=========================================================

Problem 2

Use the slope formula again, just with different values of course

m = (y2 - y1)/(x2 - x1)

m = (-9 - (-9))/(2 - (-5))

m = (-9 + 9)/(2 + 5)

m = 0/7

m = 0

In contrast to the previous problem, we can have 0 in the numerator. Dividing 0 over any nonzero value leads to 0.

This line is horizontal as both y coordinates are the same value. All horizontal lines have a slope of 0. You can think of it like

slope = rise/run = 0/1

rise = 0 means we don't move up or down

run = 1 means we move to the right 1 unit

We use negative values for the money Arleen spends.

a) We determine the change to the value on her gift card:

4(-35)+(-9)= -140+(-9)=-149

b) We determine the amount on money she has left on the gift card after renting the tiller and buying the rake:

200+(-149)=51

Since she has got $51 on her gift card and a wheelbarrow is $50 she is able to buy it:

51>50

Complete Question:

A ball is kicked with an initial height of 0.75 meters and initial upward velocity of 22 meters/second. This inequality represents the time, t in

seconds, when the ball's height is greater than 10 meters.

-4.9t² + 22t + 0.75 > 10

The ball's height is greater than 10 meters when t is approximately between __ and __ seconds

Answer:

The ball's height is greater than 10 meters when t is approximately between 0.47 and 4.02 seconds

Step-by-step explanation:

Given

[tex]-4.9t\² + 22t + 0.75 > 10[/tex]

Required

Solve the inequality

[tex]-4.9t\² + 22t + 0.75 > 10[/tex]

Subtract 10 from both sides

[tex]-4.9t\² + 22t + 0.75 - 10> 10 - 10[/tex]

[tex]-4.9t\² + 22t + -9.25> 0[/tex]

Solve using quadratic formula

[tex]t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

In this case;

a = -4.9; b = 22; c = -9.25

[tex]t = \frac{-22 \± \sqrt{22^2 - 4 * (-4.9) * (-9.25)}}{2 * -4.9}[/tex]

[tex]t = \frac{-22 \± \sqrt{484 - 181.3}}{-9.8}[/tex]

[tex]t = \frac{22 \± \sqrt{484 - 181.3}}{9.8}[/tex]

[tex]t = \frac{22 \± \sqrt{302.7}}{9.8}[/tex]

[tex]t = \frac{22 \± 17.398}{9.8}[/tex]

Split

[tex]t = \frac{22 + 17.398}{9.8}[/tex]    or      [tex]t = \frac{22 - 17.398}{9.8}[/tex]

[tex]t = \frac{39.398}{9.8}[/tex]   or     [tex]t = \frac{4.602}{9.8}[/tex]

[tex]t = 4.02[/tex] or  [tex]t = 0.47[/tex]

Convert to inequality;

[tex]0.47 < t < 4.02[/tex]

Hence;

The ball's height is greater than 10 meters when t is approximately between 0.47 and 4.02 seconds

============================================================

Explanation:

Your teacher is effectively asking "are the fractions 19/8 and 5/4 equal?"

Let's assume for now that they are. So we have 19/8 = 5/4

To check if that is a true equation, let's cross multiply

19/8 = 5/4

19*4 = 8*5

76 = 40

The last equation is not true, so the first equation is also not true. The ratios are not in proportion.

---------------------------

Alternative method:

Instead of cross multiplying, we can get all the fractions to have the same denominator. The LCD (lowest common denominator) of the two given fractions is 8. Let's turn 5/4 into a fraction with 8 in the denominator.

We'll multiply top and bottom by 2 to get 5/4 turning into 10/8

Now we're asking "are 19/8 and 10/8 the same?" in which the answer is "no they are not the same". The numerators 19 and 10 are different. The fraction 19/8 is larger than 10/8. So 19/8 is larger than 5/4.

---------------------------

2nd Alternative method:

Use your calculator to see that

19/8 = 2.375

5/4 = 1.25

The decimal values should be the same if the fractions were equal, but they are not. This is a very quick way to compare two fractions.

Answer:

Step-by-step explanation:

Given the expression sec²34°−tan²34°, to get the exact value using the fundamental identities​ and/or the complementary angle theorem, we will apply the trigonometry identity

From sin²θ+cos²θ = 1

Divide both sides of the expression by cos²θ

sin²θ/cos²θ+cos²θ/cos²θ = 1/cos²θ

tan²θ+1 =sec²θ

Since sec²θ= tan²θ+1, hence  sec²34°= tan²34°+1... 1

Substituting equation 1 into the expression given in question we will have;

sec²34°−tan²34°

=  (tan²34°+1)-tan²34°

collect like terms

= tan²34°-tan²34°+1

= 1

Hence the exact value of the expression sec²34°−tan²34° is 1
