Work out a) 1 1/5 + 3 2/5

1 answer:

5 0

First make it improper fraction :
6/5 + 17/5
Then add 6 and 17 :
23
The denominator doesn’t change :
So the answers is 23/5

Then you need to simplify it
How much times 5 goes in 23 :
4 times and 3 extra
So the FINAL ANSWER is : 4 3/5

Look at the diagram. If RS= 8y + 4, ST = 4y + 8, and RT = 36, find the value of y.

vladimir2022 [97]

<span>RS= 8y + 4, ST = 4y + 8, and RT = 36

RS + ST = RT
</span>8y + 4 + 4y + 8 = 36
12y + 12 = 36
12y = 24
y = 2

answer
y = 2 (first choice)

The equation F=9/5C+32 relates temperature measured in degrees Celsius, C, to degrees Fahrenheit, F. Determine wether there is a

Rama09 [41]

Answer: yes they have a proportional relationship

Step-by-step explanation:

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

Step one : let us test say c=1

F=9/5*1+32

F=9/5+32

F=1.8+32

F=33.8

Say c=2

F=9/5*2+32

F=9/10+32

F=0.9+32

F=32.9

Observe that as c increases

F reduces Hence they have a proportional relationship

Find the area of a triangle with a base length of 3 units and a height of 4 units. 3 square units 6 square units 7 square units

yan [13]

For this case we have that by definition, the area of a triangle is given by:

$A = \frac {b * h} {2}$

Where:

b: It is the base of the triangle

h: It is the height of the triangle

According to the data of the statement we have:

$b = 3 \ units\\h = 4 \ units$

Substituting in the formula we have:

$A = \frac {3 * 4} {2} = \frac {12} {2} = 6 \ units ^ 2$

So, the area of the triangle is $6 \ units ^ 2$

Answer:

$6 \ units ^ 2$

The rectangle below has an area of x2 + 11x + 28 square meters and a length of 2 + 7 meters.

Troyanec [42]

<h3><u>Question:</u></h3>

The rectangle below has an Área of x^2 + 11x + 28 square meters and a length of x+7 meters. What expression represents the width of the rectangle?

<h3><u>Answer:</u></h3>

The expression representing width of rectangle is (x + 4) meters

<h3><u>Solution:</u></h3>

Given that rectangle has an area x^2 + 11x + 28 square meters and a length of x + 7 meters

To find: width of the rectangle

<em><u>The area of rectangle is given as:</u></em>

$\text {Area of rectangle }=\text { length } \times \text { width }$

Here area = x^2 + 11x + 28 square meters

length = x + 7 meters

<em><u>Substituting the values in given formula,</u></em>

$\begin{array}{l}{\text { width }=\frac{x^{2}+11 x+28}{x+7}} \\\\ {\text { width }=\frac{x^{2}+4 x+7 x+28}{x+7}} \\\\ {\text { width }=\frac{x(x+4)+7(x+4)}{x+7}} \\\\ {\text { width }=\frac{(x+4)(x+7)}{x+7}}\end{array}$

Cancelling (x + 7) on numerator and denominator,

$\text { width }=(x+4)$

Thus expression representing width of rectangle is (x + 4) meters
