Please help!

Answers

Answer:

a) £58.5

b) £117

c) £438.75

Step-by-step explanation:

Mr Singh is paid £11.70 per hour after tax is deducted.

This means that for x hours of work, his earning are given by:

[tex]E(x) = 11.7x[/tex]

a) How much does he earn if he works 5 hours?

This is E(5).

[tex]E(5) = 11.7*5 = 58.5[/tex]

b) How much does he earn if he works 10 hours?

This is E(10).

[tex]E(10) = 11.7*10 = 117[/tex]

c) He works 37.5 hours per week. How much does he earn in a week?

This is E(37.5).

[tex]E(37.5) = 11.7*37.5 = 438.75[/tex]

Manny grows vegetables in a community garden.
His part of the garden is a rectangular area that is 6 yards long and 5 1/3 yards wide. What is the area of Manny’s garden? Be sure to include units in your answer.

Answers

Answer:

32 yards (squared)

Step-by-step explanation:

Length x width = area (LxW=A)

Step 1:

Length = 6 yards

Width = 5 1/3 yards

Step 2:

Multiply 6 x 5 1/3 because 6 is the length, 5 1/3 is the width, and LxW=A.

6 x 5 1/3 = 32 yards (squared)

Answers

Answer:

y=[tex]\frac{12}{11}x[/tex]+[tex]\frac{-18}{11}[/tex]

Step-by-step explanation:

What you do first is you move the 12x to the other side of the equation to get

-11y=18-12x

Move the 12x to the front to get the slope intercept form set up

-11y=-12x+18

Then divide the whole thing by -11 to get the y to become by itself

y=[tex]\frac{12}{11}x[/tex]+[tex]\frac{-18}{11}[/tex]

The 12/11 will become positive and the b value will become negative

is 4/5 greater than or less than 2/3? ​

Answers

Answer:

Yes 4/5 is greater than 2/3

Step-by-step explanation:

Because

4/5 = 0.8

2/3 = 0.667

Then, we compare the two decimal numbers to get the answer.

0.8 is greater than 0.667.

Therefore, 4/5 is greater than 2/3 and the answer to the question "Is 4/5 greater than 2/3?" is yes.

State the postulate or theorem you would use to prove each pair of triangles congruent. If the triangles cannot be proved congruent, pick not possible

Answers

You would use the SSS, ASA, AAS, RHS theorems to prove two triangles to be congruent.

The triangles can be proven similar by the congruent theorem of triangles

What are Congruent Triangles?

Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape

The three sides are equal (SSS: side, side, side)

Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)

Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)

A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)

Given data ,

Let the two triangles be ABC and DEF

Now , the two triangles will be similar if

The three sides are equal

So , AB = BC = CD and

DE = EF = FD

And the two triangles are congruent if

By ASA theorem - two angles are the same and a corresponding side is the same

And ,

By SAS theorem : Two sides are equal and the angle between the two sides is equal

And ,

By RHS theorem : A right angle, the hypotenuse and a corresponding side are equal

Hence , the triangles ABC and DEF is similar ΔABC ≅ ΔDEF

Fire works are fired vertically upwards from a platform 10 feet above the ground and with an initial velocity of 96 feet per second what is the highest possible point for the fireworks to explode

Answers

Answer:

Here is the answer

Step-by-step explanation:

The highest possible point for the fireworks to explode is to be considered as the 154 feet.

Calculation of the highest possible point:

Since the equation is

[tex]h = -16t^2 + 96t 10[/tex]

Now based on this, we have to determine the axis of symmetry

So,

[tex]t = -b \div 2a\\\\= -96 \div 32[/tex]

= 3

Now

[tex]= -16(3)^2 + 96(3) + 10[/tex]

= 154 feet

hence, The highest possible point for the fireworks to explode is to be considered as the 154 feet.

Zack has an old car. He wants to sell it for 15% off its current value. The market value is
$500. How much money would he receive in exchange for the car if he sells it at that rate?

Answers

425 dollars is 500 with a 15% discount

Answer:

$425

Step-by-step explanation:

The easiest way of calculating discount is, in this case, to multiply the normal price $500 by 15 then divide it by one hundred. So, the discount is equal to $75. To calculate the sales price, simply deduct the discount of $75 from the original price $500 then get $425 as the sales price.
