Answer :
Equation :
2y + 3 = 51
Solving :
• 2y + 3 = 51
• 2y = 51 - 3
• 51 - 3 = 48
• 2y = 48
• y = 48 ÷ 2
• 48 ÷ 2 = 24
• so , y = 24

What is the perimeter of his vegetable garden? [best answer gets brainliest]
Answer:
about 15.328 yrds
Step-by-step explanation:
two sides are 5 yrds, so 5+5= 10yrds. two sides are 8 ft, 8+8=16 ft. there are .3333 yrds in 1 foot so 16*.3333 = about 5.328yrds

A) price (increased or decreased) by %
B) price (increased or decreased( by %
Answer:
a) Price increased by 75%
b) Price decreased by 42.85% (or 43% approximate)
Step-by-step explanation:
$ 40 increased by ____ % to $70
[tex]Percentage\ increase = \frac{difference}{ original} \times 100[/tex]
[tex]= \frac{70 - 40 }{40} \times 100\\\\=\frac{30}{40} \times 100\\\\= 75 \%[/tex]

if p (x) = 3x^3+2x^2+4x^4+3 and q (x) = 3x^4-2-x+5^2 .find p (x) - q (x)
Answer:
4x⁴-3x⁴+5x³-3x²+1
Step-by-step explanation:
Given that p (x) = 3x^3+2x^2+4x^4+3 and q (x) = 3x^4-2-x+5x^2
p (x) - q (x) = 3x^3+2x^2+4x^4+3 - (3x^4-2-x+5x^2)
p (x) - q (x) = 3x^3+2x^2+4x^4+3 - 3x^4 + 2 + x - 5x^2
Collect the like terms
p (x) - q (x) = 4x⁴-3x⁴+3x³+2x²-5x²+x+3-2
p (x) - q (x) = 4x⁴-3x⁴+5x³-3x²+1

You want to buy the largest pizza in Northern Utah. You find a pizza that measures
75.36in around. What is the area that the pizza covers?
Answer:
451.7in^2
Step-by-step explanation:
You first need to determine the radius of the circle. This can be done by taking the circumference and dividing it by 2pi:
[tex]r=\frac{75.36in}{2\pi } = 11.99 in[/tex]
Now that you have the radius, you can plug it into the formula for the area of a circle (this is assuming the pizza is perfectly round):
[tex]A=\pi r^2=\pi (11.99^2)=451.7in^2[/tex]
The area that covers the circular pizza is: 451.64 in.²
What is the Area and Perimter of a Circle?Area = πr²
Perimeter = 2πr, where r is the radius of the circle.
Given the following:
Perimeter of the circular pizza = 75.36 in.
Find the radius:
2πr = 75.36
r = 75.36/2π
r = 11.99 in.
Find the area:
Area = π(11.99)²
Area = 451.64 in.²

Find the measure of angle 2
Answer:
∠ 2 = 104°
Step-by-step explanation:
- 8x - 48 = 9x + 275 [ alternate angles are equal ]
-8x - 9x = 275 + 48
-17x = 323
x = -19
9x + 275 = 9 × -19 + 275
= - 171 + 275
= 104°
∠ 2 = ( 9x + 275 ) [vertically opposite angles ]
∠ 2 = 104°
If there are 10 marbles in a bag 1/5 of them are red and the others are blue. What is the ratio of red marbles to blue marbles ?
Answer:
4:1
Step-by-step explanation:
We know 1/5 of the marbles are red.
There are 10 marbles.
1/5 is also 2/10, so:
2 of the 10 marbles are red.
To find the blue marbles, lets subtract the red marbles from the total marbles:
10-2=8
So 8 of the marbles are blue.
This is a ratio of 8 blue to 2 red marbles.
Or
4 blue to 1 red marbles.
This can be shown as:
4 : 1

What is the radius of a hemisphere with a volume of 920 ft^3 to the nearest tenth of a foot?
Answer:
7.6 ft
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
A hemisphere is 1/2 of a sphere
V = 1/2 (4/3 pi r^3)
V = 2/3 pi r^3
920 = 2/3 pi r^3
Multiply each side by 3/2
920 * 3/2 = 3/2 * 2/3 pi r^3
1380 = pi r^3
Divide each side by pi
1380/pi = pi r^3 / pi
1380/ pi = r^3
Using pi as 3.14
1380/3.14 = r^3
439.4904459= r^3
Taking the cube root of each side
(439.4904459)^(1/3)= r^3^(1/3)
7.602967711=r
To the nearest tenth
7.6 = r
radius=7.6ft
Answer:
Solution given:
radius [r]=?
Volume of hemisphere=920ft³
⅔*πr³=920
r³=920*3/(2π)
r³=439.267
r=[tex]\sqrt[3]{439.267}=7.6ft[/tex]
Which of the two functions below has the smallest minimum y-value?
f(x) = x5 - 2
g(x) = 3x2 + 1
A. The y-values for f(x)and g(x) both go to -
B. There is not enough information to determine
C. g(x)
O D. f(x)
Answer:
They have no minimum y -value
The minimum value for y belongs to f(x) at x=0 and function f(0)=(-2), Option D is correct.
The given function f(x)= x⁵-2
Differentiating the function we get,
5x⁴=0
x=0
Therefore, f(x)=f(0)=0-2=(-2)
Now function g(x)=3x²+1
Differentiating the function we get,
6x=0
x=0
Therefore, g(x)=g(0)=0+1=1
The minimum value for y belongs to f(x) at x=0 and f(0)=(-2)

Answer:
42
Step-by-step explanation:
From the question, we have it that 63 cups were emptied
That means the sum of both cup sizes is 63
Thus;
x + y = 63 ••••••(i)
Since each small cup is of size 8 oz and a total of x was used. The total volume from the small sized cup is 8 * x = 8x oz
similarly for the medium sized, we have 12 * y = 12y oz
The sum of both is 4(147)
8x + 12y = 4(147 )•••••(ii)
We want to get the value of x
from equation i;
y = 63-x
Substitute this into equation ii
8x + 12(63-x) = 4(147)
8x + 756 - 12x = 4(147)
12x-8x = 756-4(147)
4x = 168
x = 168/4
x = 42 small sized cups
Volume and surface area are often compared by manufacturers in order to maximize how much of something can go inside of a package (volume) while keeping how much material is required to create the package (surface area) low.
Pick a product that might be packaged in the shape of a rectangular prism. A rectangular prism has three dimensions: length, width, and height. The surface area of a rectangular prism can be found using the formula SA = 2lw + 2wh + 2lh. The volume of a rectangular prism can be found using the formula V = lwh. Write an expression for the ratio of surface area to volume for the figure.
Choose an appropriate length, width, and height for your package so that it can fit the product you are shipping. Using these dimensions, what is the ratio of surface area to volume?

What is the circumference of a circle with a radius of 9.7 inches?
Use 3.14 for pi.
Enter your answer as a decimal in the box.
==================================================
Work Shown:
C = 2*pi*r
C = 2*3.14*9.7
C = 60.916
This value is approximate since pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate circumference. The circumference is the distance around the circle, aka the perimeter.
Answer:
60.916
(rounded to the two nearest decimals = 60.92, and to the first decimal = 60.9)
Step-by-step explanation:
Circumference formula: 2πr
π being pi and r being radius
Fill in your variables: 2(3.14)(9.7) or 2 x 3.14 x 9.7
use your calculator or simply solve it and you end up with 60.916.
