Answer:

D

Step-by-step explanation:

when you add 5.1 and 7.7 together it would be 12.8 but you have to move the decimal to the left again since it has more than one number to the left then the ^5 would turn into ^6 and 1.28x10^6 is 1,280,000 and the other is only 1,000,000

Answer:

$21.50

Step-by-step explanation:

We want to find Anthony's pay for 43 hampers.

We can multiply his pay per hamper by the number of hampers picked.

pay per hamper * hampers picked

He earns $0.50 for each hamper and he picked 43 hampers. Therefore, we can multiply $0.50 and 43 to find his pay for the day.

$0.50 * 43

$21.5 = $21.50

Anthony's total pay that day is $21.50.

Answer: your answer is going to be 1/7

Step-by-step explanation:

Answer:

x = -1/7

Step-by-step explanation:

First, combine like terms:

3 - 21x = 6

Then, isolate the variable:

-21x = 3

Then, divide -21 on both sides:

x = -3/21

Finally, simplify the fraction:

x = -1/7

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:

no

Step-by-step explanation:

-7 is bigger

Answer:

no, its less

Step-by-step explanation:

because in negatives the higher the number is (ex: -10) the less the value is, so its the opposite of positive numbers

Negative seven multiply three minus negative thirty seven multiply two equal to seventy four minus twenty one equal to fifty three.

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

Step-by-step explanation:

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

0.47 and 4.02

Answer: 22.59 yd^3

Step-by-step explanation:

First the volume of a cuboid whose measurements are:

L = length, W = width and T = thiknes is:

V = L*W*T.

We want to calculate the volume of a shape that is:

10'' thick, 18' wide and 42' long.

This notation is:

(') = feet

('') = inches

The first step is to write our 3 numbers in the same units, then we can use that:

1 inch = 0.083 ft.

Then 10 inches are equal to:

10'' = 10*(0.083 ft) = 0.83 ft = 0.83'

Then the volume of concrete needed will be:

V = 0.83ft*18ft*42ft = 627.48 ft^3

But we want this expressed in yd^3

1ft = 0.33 yd

then

1ft^3 = (0.33 yd)^3 = 0.036 yd^3

then 627.48 ft^3 can be written as:

627.48 ft^3 = 627.48*( 0.036 yd^3) = 22.59 yd^3

Answer:

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

RESULT

a) -$149 less b) yes

Answer: It is because if ∠N and ∠K are congruent and are same in size and shape.

Answer:

KLM is equal to NLM because in order to share a bisector, they have to have the same length. Also we can assume that <L and <M are the same since they share the same vertex, making both triangles equal.

Step-by-step explanation:

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

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:

no

Step-by-step explanation:

because they are not equivalent to each other.
