Remark

There are three rectangles all the same size.

There are two triangles both the same size

Triangles.

Givens

b = 7.5 cm

h = 6.5

Solution

Area 1 triangle =   1/2 * 7.5 * 6.5

Area 1 triangle = 24.375

Area 2 triangles = 2*24.375 =                            48.75

Rectangles

Givens

L = 13.5

w = 7.5

Solution

Area one rectangle = L*w

Area one rectangle = 13.5*7.5

Area one rectangle = 101.25

Area three rectangles =  3*101.25

Area three rectangles =                                   303.75    Add

Total Area =                                                      352.5

A system of linear equations is shown below. 3x+5y=9 2x+3y=5 which ordered pair shows the solution to the system

Answers

Answer:

(-2,3)

Step-by-step explanation:

Given data

the system of linear equation is presented as

3x+5y=9-----1

2x+3y=5-----2

solve simultaneously

3x+5y=9-----1  X 2

2x+3y=5-----2  X3

subtracting 2 from 1

 6x+10y=18

-6x+9y=15

0x+y=3

y= 3

put y= 3 in 1

3x+5(3)=9-----1

3x+15=9

3x= 9-15

3x= -6

x= -6/3

x= -2

Hence the ordered pair is (-2,3)

Taut learns that when she spends $65.00 on supplies she is able to grow 162.5 pounds of tomatoes. How many dollars is Taut spending per pound of tomatoes grown?

Answers

Answer: $0.4 is spent by Taut  per pound of tomatoes grown

Step-by-step explanation:

Given : On spending $65.00 , tomatoes grown by Taut = 162.5 pounds

To find :  Taut expenditure per pound of tomatoes grown = ?

As it is given that :

162.5 pounds of tomatoes are grown by spending = $65.00

Thus 1 pound of tomatoes are grown by spending = [tex]\frac{65.00}{162.5}\times 1=0.4[/tex]

Thus $0.4 is spent by Taut per pound of tomatoes grown

The LCM of two numbers is 14 times their HCF. The sum of LCM and HCF is 600. If one number is 280, then find the other number.

Answers

Given:

The LCM of two numbers is 14 times their HCF.

The sum of LCM and HCF is 600.

One number is 280.

To find:

The other number.

Solution:

Let HCF of two numbers be x.

The LCM of two numbers is 14 times their HCF.

LCM = 14x

The sum of LCM and HCF is 600.

[tex]14x+x=600[/tex]

[tex]15x=600[/tex]

[tex]x=\dfrac{600}{15}[/tex]

[tex]x=40[/tex]

So, HCF = 40 and the LCM is

[tex]LCM=14(40)[/tex]

[tex]LCM=560[/tex]

We know that, if a and b are two numbers, then

[tex]a\times b=LCM(a,b)\times HCF(a,b)[/tex]

One number is 280.

[tex]280\times b=560\times 40[/tex]

[tex]b=\dfrac{560\times 40}{280}[/tex]

[tex]b=2\times 40[/tex]

[tex]b=80[/tex]

Therefore, the other number is 80.

In QRS q=9.6 inches r=9.9 inches and S=92 Find the length of a to the nearest 10th of an inch

What is Trigonometry?

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

In ΔQRS q=9.6 inches r=9.9 inches and S=92.

So, s² = q² + r² - 2qr cos s

s² = 9.6² + 9.9² + 2(9.6)(9.9) cos 92.

s² = 190.71 + 190.08 x (-0.035)

s² = 183.52

s = 13.55

s = 13.6 inches

Answers

Answer:

answer to top question:  x = 3/17

answer to bottom question:  x = -1

Step-by-step explanation:

distribute first

5 + 4x - 6 + 8x = -5x + 2

combine like terms

-1 + 12x = -5x + 2

12x = -5x + 3

17x = 3

x = 3/17

What is the volume of this rectangular prism?

Answers

Answer:

1cm³

Step-by-step explanation:

You do not need a calculator for this.

The formula for the volume of a rectangular prism is:

Length × Width × Height = Volume

If we substitute our numbers in:

5/4 × 4/3 × 3/5 = 1cm³

All you need to do is multiply across.

5 × 4 × 3 = 60

4 × 3 × 5 = 60

The numerator and denominator both equal 60. So the fraction would look like this if you were to keep it as a fraction.

A rectangle has sides of length 8cm and 3.2cm. Calculate the angle between the diagonal and a shorter side.

Answers

Answer:

The angle is 68.2 degrees

Step-by-step explanation:

Let us have the shorter side as the width

In that case, the opposite will be the length which is 8 cm

The diagonal is the hypotenuse

The short side is the adjacent

The trigonometric ratio that links the opposite and the adjacent is the tan

tan of an angle is the ratio of its opposite to the adjacent

In this case,

tan theta = 8/3.2

theta = arc tan (8/3.2)

theta = 68.2 degrees
