Answer:
$276
Step-by-step explanation:
Given that
Last week Lola made 32kg of different kind of bun
The quarter of the bun sold at $9 per kilo
And, the rest would be sold at $8.5 per kilo
We need to find out the amount that should be collected in total from the sale
A quarter of the 32 buns is 8 buns
And, the half of 32 is 16, and half of 16 is 8.
Now If he sold those 8 buns for $9
So, the total amount is
= (8 buns) ($9)
= $72
Now the remaining buns left is
= 32 - 8
= 24 buns
It would be sold at $8.50
So, the total amount is
= (24) ($8.50)
= $204
Now the final amount is
= $204 + $72
= $276
Explain how to simplify the rational expression x2 - 2x -89x2 - 16x2 - 163x2 + 10 x + 8. (be sure to include the simplified rational expression)
Answer:
267x2 -8x -8 where
x=- 4± 2√ 538/267
Step-by-step explanation:
x2 - 2x -89x2 - 16x2 - 163x2 + 10 x + 8
= x2 -89x2 - 16x2 - 163x2 - 2x+ 10 x + 8
= -267x2+8x +8
= 267x2 -8x -8
First the like terms are arranged and then added . All the co efficients of x2 are added and x are added separately.
Using the quadratic equation to find the value of x
a= 267 , b= -8 and c= -8
x= -b±√b²- 4ac/ 2a
x= -8±√64 +8544/534
x= -8±√8608/534
x=-8±√ 2 x 2 x 2 x 2 x 2 x 269/534
x=-8± 4√ 2 x 269/534
x=- 4± 2√ 2 x 269/267
x=- 4± 2√ 538/267

Amy had $28 dollar’s to spend on school supplies. After buying 7 pens, she had $20.30 left. How much did each pen cost including tax?
Answer:
Step-by-step explanation:
If Amy started with 28 dollars and bought 7 pens, then had 20.30 dollars, we can subtract to find the price of all 7 pens.
28-20.30=7.70 dollars
now to find the amount for EACH pen, we divide by 7
7.70/7=1.1
each pen costed Amy 1 dollar and 10 cents with tax
Answer:
$1.10
Step-by-step explanation:
$28-$20.30=$7.70
7.70 divided by 7= 1.10
so each pen must cost $1.10
Which justification can be used to demonstrate the graph is correct?
The justification (D) shading is to the left because (0, 0) does not satisfy the inequality option (D) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have inequality:
[tex]\rm x+3.5 < \dfrac{1}{10}(y-2)^2[/tex]
If plug (0, 0)
0 + 3.5 < 4/10
Which is not true.
Thus, the justification (D) shading is to the left because (0, 0) does not satisfy the inequality option (D) is correct.

Sarah is finding the surface area of a cube. Find the surface area of the cube with dimensions of 8 cm each
Answer:
384 cm^2
Step-by-step explanation:
A = 6a^2 (a = side length)
A = 6(8^2)
A = 6(64)
A = 384 cm^2
More explain stuff:
a^2 is what is used to find the area of a 2 dimensional square. You can also use a · a. Remember, a = side length. Since there are 6 sides/faces in a cube, you multiply the area of each face by 6. :D

Trent attaches his A+ test to the refrigerator with a circular magnet. Out of curiosity, he measures the magnet and calculates that it has a diameter of 4 centimeters. What is the magnet's area?
Answer:
12.6 cm²
Step-by-step explanation:
From the above question, the magnet is circular in shape
The area of a circle is given as:
= πr²
The area of the magnet = π × r²
Diameter = 4cm
r = Diameter/2 = 4cm/2 = 2cm
= π × (2cm)²
= 12.566370614cm²
Approximately = 12.6 cm²
The area of the magnet = 12.6cm²
