7) C. Php1 500, Php403 and 3 cans of paints

8) A. Php291

9) B. Php1 170

10) D. Php840

Step-by-step explanation:

Alona bought 3 cans of paint for Php403 p er can. She gave the salesclerk Php1 500. How much change did she get?

6.) What is asked in the problem?

Aloha was asked of her change. This means the amount that is left after buying the 3 cans of paint. Hence, option C is correct.

C. amount left in her money

7. )What are the given facts?

The given facts in the question are

The 3 cans of paint that cost Php 403 and the amount she paid the clerk which is Php 1500

Hence, Option C. Is correct.

C. Php1 500, Php403 and 3 cans of paints

8. )How much change did she get?

The amount for change she got is calculated as.

Php 1 500 - 3(Php 403)

= Php 1 500 - Php 1 209

= Php 291

The amount of change she got is Php 291

Option A. Php291 is correct

9.) Lilia has six Php100 bills, seven Php50 bills and eleven Php20 bills. How much does she have?

The question above can be interpreted as:.

Six Php100 bills

= 6 (Php100)

= Php 600

Seven Php50 bills

7 (Php50)

= Php 350

Eleven Php20 bills

11 (Php20)

= Php 220

The amount she she has is calculated as:

Php 600 + Php 350 + Php 220

= Php 1 170

Hence, Option B. Php1 170 is correct

10.) Mang Jose is a tricycle driver. He charges Php10 for every passenger he transports. The tricycle carries 4 passengers each trip. How much does he earn for 21 trips?

We are told that:

He charges Php10 for every passenger he transports. The tricycle carries 4 passengers each trip.

Hence, the cost for each trip is

Php 10 × 4 passengers

= Php 40

Hence:

1 trip = Php 40

21 trips = x

Cross Multiply

x = 21 trips × Php 40

x = Php 840

Option D. Php840 is correct

Answer:

y = -5x/6 - 33/6

Step-by-step explanation:

The standard form of equation of a line in point slope form is y - y0 = m(x - x0)

m is the slope

(x0, y0) is the point on the line

First we need the slope of the given equation 5x+6y=11.

Rewrite in standard form;

5x+6y=11

6y = -5x + 11

y = -5/6 x + 11/6

Hence the slope is -5/6

Since the unknown line is parallel to this line, they will have the same slope, hence the slope of the required line is -5/6

Substitute m = -5/6 and the point (-5,-3) into the point-slope expression;

y - y0 = m(x - x0)

y - (-3) = -5/6 (x - (-5))

y + 3 = -5/6(x+3)

6(y+3) = -5(x+3)

6y+18 = -5x - 15

6y+5x =-15 -18

6y+5x =-33

Express in slope intercept form

6y = -5x - 33

y = -5x/6 - 33/6

Answer: 104 left handed students

Step-by-step explanation:

Ratio: 9:2

We should divide 468 by 9, use the number we find, and then multiply it by 2.

468 / 9 = 52

52 x 2 = 104.

There are 104 left-handed students in the school.

Answer:

Jerry's current balance is $41.

Step-by-step explanation:

We need to subtract what he spent, and add what he gained.

So:

(Money spent)

$18 + $20 = $38

(Current balance)

$52 - $30 = $22

(Current balance)

$65 + $22 = $87

$25 + $16 = $41

Current balance: $41

Answer:

[tex]f[2-f^{-1}(x)]=x[/tex]

Step-by-step explanation:

Given function is,

f(x) = [tex]\frac{x-1}{2}[/tex]

Equation form of the function will be,

y = [tex]\frac{x-1}{2}[/tex]

Interchange x and y,

[tex]x=\frac{y-1}{2}[/tex]

Solve for y,

y = 2x + 1

Therefore, inverse of the function 'f' will be,

[tex]f^{-1}(x)=2x+1[/tex]

Now [tex][2-f^{-1}(x)][/tex] = 2 - [2x + 1]

                          = -2x + 1

Value of [tex]f[2-f^{-1}(x)][/tex] = f(2x + 1)

From the given function,

f(2x + 1) = [tex]\frac{(2x+1)-1}{2}[/tex]

            = x

Therefore, value of  [tex]f[2-f^{-1}(x)]=x[/tex]

Answer:

B. y=7x+3

Step-by-step explanation:

You find the changes of y over the changes of x. y sub 2 - y sub 1 divided by x sub 2 over x sub 1. So, 17 - 10 over 2 - 1 = 7. 3 is the y-intercept. y=7x+3

Step-by-step explanation:

Ben will likely lay more bricks than Caleb. Because Ben has higher efficiency.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
As mentioned in the question,
Ben and Caleb work for a landscaping company. On Monday, they worked on two different walkways.

Since They laid the same number of bricks, but Ben finished first.

Now, On Tuesday, they are going to work together to build the brick border of a patio. they work for the same amount of time on Tuesdays,
But Ben has higher working efficiency so Ben will lay more bricks than Caleb.

Thus, Ben will likely lay more bricks than Caleb.

Answer:

18.8 cubic inches

Step-by-step explanation:

✔️Amount of juice Cup B will hold than Cup A = Volume of cup B - volume of cup A

✔️Volume of Cup B = Volume of cylinder = πr²h

radius (r) = ½ of 2 = 1 in.

height (h) = 7 in.

Volume of cup B = π*1²*7 = 21.99 in.³

✔️Volume of Cup A = Volume of cone = ⅓πr²h

radius (r) = ½ of 2 = 1 in.

height (h) = 3 in.

Volume of cup B = ⅓*π*1²*3 = 3.14 in.³

✔️Amount of juice Cup B will hold than Cup A = 21.99 in.³ - 3.14 in.³ = 18.8 in.³ (nearest tenth)

Step-by-step explanation:

Guy above is wrong, I took it just now.

Answer:

3.5 cm

Step-by-step explanation:

The computation of the approximate length of minor arc JH is as follows

As in the attached picture we can see that circle M is shown also the minor arc measures 25 degrees

Now the circle length is

= π × 16

= 50.26 cm.

Now this length would be proportional to 360 degrees

Let us assume the minor length arc JH be x

So, the equation would be

50.26 cm ÷  x cm = 360° ÷ 25°

x = 50.26 × 25 ÷ 360

x = 3.5 cm

Answer:

A. 3.5 cm

Step-by-step explanation:

In the picture attached, circle M is shown.

From the picture, minor arc JH measures 25°.

The length of the circle is π*Diameter = π*16 = 50.26 cm. This length is proportional to 360°. To find the length of minor arc JH, we have to use the next proportion:

50.26 cm / x cm = 360° / 25°

x = 50.26*25/360

x = 3.5 cm

Answer:

593.14 m

Step-by-step explanation:

Given that :

Length of rig visible above water surface (sea. Level) = 74.98m

Length of rig below surface of water (sea level) = 518.16 m

The total height of the rig:

The surface of water is usually regarded as a zero point ;

Hence. The total height of rig will be the sum of the height above sea level and the length below water surface

=(74.98 + 518.16) m

= 593.14 m
