Amber earns £7 for each hour she works from Monday to Friday. She earns £10 for each hour she works on Saturday. One week Amber worked for 4 hours on Saturday. That week she earned a total of £180 (a) How many hours did Amber work that week?

Answer:

What do you need help with?

1. -9(T-2)=4(T-5)

Distribute

-9t+18=4t-5

Sub 4 because t is a like term and it is positive so sign changes because it is in opposite sides.

-14t+18=-5

Sub 18 to like term which is -5

-14t=-23

Divide

T= -14/-23 or -0.4375

2. 2(4x+2)=4x

Distribute

8x+4= 4x

Sub 8x

4=-4x

Divide -4x

X=-1

3. 26-4s=9s

Sub -4s

26=5s

Divide 5s

Answer:

answer a did the test edg 2021

Step-by-step explanation:

Using translation concepts, it is found that the equation that represents the transformed function is:

[tex]y = -\sqrt{x-4} + 2[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the original graph is:

[tex]y = \sqrt{x}[/tex]

It moves up, while the new graph moves down, hence:

[tex]y = -\sqrt{x}[/tex]

It starts at (0,0), while the new graph starts at (0,2), hence:

[tex]y = -\sqrt{x} + 2[/tex]

It also goes through (4,0), that is, it was shifted 4 units to the right, hence:

[tex]y = -\sqrt{x+4} + 2[/tex]

Answer:

The average rate of change of the function over the interval x = 0 to x = 6 is [tex]\frac{34}{195}[/tex].

Step-by-step explanation:

Geometrically speaking, the average rate of change ([tex]r[/tex]) of the function over a given interval is determined by equation of secant line, that is:

[tex]r = \frac{f(b)-f(a)}{b-a}[/tex] (1)

Where:

[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds.

[tex]f(a)[/tex], [tex]f(b)[/tex] - Function evaluated at lower and upper bounds.

If we know that [tex]f(x) = \frac{2\cdot x -1 }{3\cdot x + 5}[/tex], [tex]a = 0[/tex] and [tex]b = 6[/tex], then the average rate of change of the function over the interval is:

[tex]f(a) = \frac{2\cdot (0)-1}{3\cdot (0) +5}[/tex]

[tex]f(a) = -\frac{1}{5}[/tex]

[tex]f(b) = \frac{2\cdot (6)-1}{3\cdot (6)+5}[/tex]

[tex]f(b) = \frac{11}{13}[/tex]

[tex]r = \frac{\frac{11}{13}-\left(-\frac{1}{5} \right) }{6-0}[/tex]

[tex]r = \frac{34}{195}[/tex]

The average rate of change of the function over the interval x = 0 to x = 6 is [tex]\frac{34}{195}[/tex].

Answer:   3pi/2

This is equivalent to 1.5pi

The units for the area are in square centimeters.

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

Work Shown:

The larger semicircle has radius 2 cm.

So r = 2 is plugged into the area of a semicircle formula below

A = (pi*r^2)/2

A = (pi*2^2)/2

A = (4pi)/2

A = 2pi

The area of the larger semicircle is 2pi square cm.

Repeat those steps but now use r = 1. This will compute the area of the unshaded smaller semicircle

A = (pi*r^2)/2

A = (pi*1^2)/2

A = pi/2

The area of the smaller unshaded semicircle is pi/2 square cm.

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

From here, we subtract the two results to get the shaded area:

(larger semicircle area) - (smaller semicircle area) = (2pi) - (pi/2) = 3pi/2

This is equivalent to 1.5pi since 3/2 = 1.5

Answer:

{-5, 4}

Step-by-step explanation:

Start by factoring f(x) = x^2 + x - 20.  Since 4*5 = 20, we suspect that the factors are (x + 5) and (x - 4).

Next, set these factors equal to zero separately and solve each resulting equation for x.  We get:

{-5, 4}

Answer:

D

Step-by-step explanation:

the theoretical probability is a fancy term for an even amount of both, which would be 20 flips landing on H, and 20 landing on T. Since the question is asking what's the difference between the theoretical probability and the experimental results, you'd take 20(theoretical number of flips that land on H) and subtract 15 (experiment results for the amount of flips that land on H), and 20 - 15 = 5. Now that you know the difference is 5, you would divide 5 by 40 to find the answer. 5/40 = 1/8 when you simplify, making the answer D.

Answer:

The original price of computer is $ 1040

Solution:

Given that, Mason used a 30% coupon to buy a new computer

After the discount, the cost of the computer was $728

To find: original price of computer

From given question,

price after discount = $ 728

discount = 30 % of original price

Let "x" be the original price of computer

price after discount = original price - discount price

Answer: 6/12 and 10/12

12/24 and 20/24

Step-by-step explanation:

Jessica bought 1/2 pound of roast beef and 5/6 pound of ham.

1st option: 8/16 and 10/16

We will reduce them to lowest term

8/16 = 1/2

10/16 = 5/8

2nd option: 6/12 and 10/12

We will reduce them to lowest term

6/12 = 1/2

10/12 = 5/6

3rd option: 5/10 and 8/10

We will reduce them to lowest term

5/10 = 1/2

8/10 = 4/5

4th option: 12/24 and 20/24

We will reduce them to lowest term

12/24 = 1/2

20/24 = 5/6
