Answer:

Fraction form: [tex]\frac{3}{2}[/tex]
Decimal form: 1.5
Mixed number form: 1 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Find the greatest common factor between the two numbers in the fraction, in this case the largest number both can be divided by equally is 2, so,

Take [tex]\frac{6}{4}[/tex] and divide both parts by 2:

6 ÷ 2 = 3

Find the slope and the y intercept of the line -7x-2y=10

Answers

Answer:

Gradient = -3.5, y - intercept = ( 0 , -5 )

Step-by-step explanation:

→ Rewrite into y = mx+ c format

-2y = 7x + 10

→ Divide everything by 2

-y = 3.5x + 5

→ Multiply everything by -1

y = -3.5x - 5

For $1.80 a grocer buys a case of fruit which contains 12 dozen. He knows that 2 dozen will spoil before he sells them. At what price per dozen must he sell the good ones to gain 1/3 of the whole cost?

Answers

Answer:

i didnt understand the awnser fully but if i did the awnser is 5 cents a donut

Step-by-step explanation:

I assume you mean she wants to make 50% profit, based on a cost of $1.80/dozen. (The wording is ambiguous. If the problem was presented as you posted it, it's from a pretty sloppy text.)

10x = 1.5(1.80*12)
x = 3.24

For the equation z – 14 = 29. Jaun says that the solution is 33.Check solution work by substitutions it into the equation .Is his solution correct. Explain

Answers

Answer:

Jaun's solution is incorrect.

Step-by-step explanation:

If Jaun's solution to the equation is 33, we can check this by substituting z=33 and solving 33 - 14 = 29. Since 33-14=19 and 19 does not equal 29, Jaun's answer is incorrect.

use Mental Math to determine if the circumference of a circle with a radius of 5in will be greater than or less than 30 in write an argument that can be used to justify your solution​

Answers

Answer:

It will be greater than 30.

Step-by-step explanation:

(Any following math is easy to do in your head and therefore mental math.)

In order to find the circumference, you multiply the diameter by pi.

The radius is half of the circumference so if you double the radius you get the circumference.

5 × 2 = 10

The default for pi is 3.14, so it's a little more than 3.

10 × 3 = 30

If just 3 is 30, then anything more ( like the 0.14), will make it over 30.

Step-by-step explanation:

The third ordered pair using the two sequences as described in the task content is; (two and one third, 106).

What is the third ordered pair of the two sequences?

It follows from the description of the task content that the third ordered pair of each sequence is as follows;

Sequence 1; 0(2)+1/3 = 1/3(2) + 1/3 = 1(2) + 1/3 = 2 1/3.

Sequence 2; (1+1/2)4 = (6+1/2)4 = (26 +1/2)4 = 106.

On this note, it follows that the required ordered pair is; (two and one third, 106).

A=p2-2p-3

Step-by-step explanation:

The area for a triangle is given by:

A=1/2bh

The base is p + 1 and the height is 2p - 6. Therefore:

A=1/2(p+1)(2p-6)

Simplify the second term:

A=(p+1)(1/2)(2p-6)=(p+1)(p-3)

Distribute:

A=p(p-3)+1(p-3)

Distribute:

A=p2-3p+p-3

Length of shoebox = 12 in

width = 6 in

height = 5 in

The Total surface area of cuboid = 2(lw + lh + wh )

To find the volume of a triangular prism:

 ⇒ necessary to know the formula

     [tex]Volume = (Area-of-Triangular- base)*(length)[/tex]

Let's first find the area of the triangular base:

 ⇒the formula for the finding the area of a triangle is ⇒ [tex]\frac{1}{2}bh[/tex]

b: length of base --> 3mmh: length of height: 6mm

     Area of the triangle is  [tex]\frac{1}{2}*3*6=3*3=9[/tex]

Since the area of the triangular base is 9 and the length is 5.22

 ⇒ the volume is:

         [tex]Volume = 9 * 5.22=46.98mm^3[/tex]

When the volume is rounded to the nearest tenth, the volume is 47.0 [tex]mm^3[/tex]
