What is the approximate volume of the sphere? Use and round to the nearest whole cubic unit. 42 cubic units 126 cubic units 4187 cubic units 73,385 cubic units
The question is incomplete, the complete question is;
The radius of the sphere is 10 units.What is the approximate volume of the sphere? Use π = 3.14 and round to the nearest whole cubic unit. cubic units
Answer:
4187 cubic units
Step-by-step explanation:
According to the question;
radius (r) = 10 units
π = 3.14
Volume of a sphere = 4/3*π*r^3
Substituting values;
V = 4/3*(3.14)*(10)^3
V = 4186.67 cubic units
V = 4187 cubic units (To the nearest whole cubic unit)

what is the length of the unknown side
Answer: ↓↓↓
Step-by-step explanation:
1. a = ? b = 16 c = 18
a² + b² = c²
a² + (16)² = (18)²
a² + 256 = 324
- 256 -256
a² = 68
√a² = √68
a ≈ 8.25
2. a = 4 b = 8 c = ?
a² + b² = c²
(4)² + (8)² = c²
16 + 64 = c²
80 = c²
√c² = √80
c ≈ 8.94

f(-2) is x = -2
Step 2: Evaluate
Substitute in x: f(-2) = -3(-2)² - 5(-2) + 11Exponents: f(-2) = -3(4) - 5(-2) + 11Multiply: f(-2) = -12 + 10 + 11Add: f(-2) = -2 + 11Add: f(-2) = 9Una torta de queso para 4 personas presisa 300g de queso, 10ml de leche, 100g de azucar, 100g de mantequilla y 50g de harina, si queremos hacer una tarta para 6 personas, qué cantidad de ingredientes necesitaremos?
Answer:
Por tanto, la cantidad de ingredientes necesarios para 6 personas es:
450 g de queso, 15 ml de leche, 150 g de azúcar, 150 g de mantequilla y 75 g de harina.
Step-by-step explanation:
Por lo tanto:
Para queso
4 personas = 300g de queso
6 personas = x
Cruz multiplicar
4x = 6 × 300g
x = 6 × 300 g / 4
x = 450 g de queso
Por 10ml de leche
4 personas = 10 ml de leche
6 personas = x
Cruz multiplicar
4x = 6 × 10 ml
x = 6 × 10 ml / 4
x = 15 ml
Por 100 g de azúcar
4 personas = 100 g de azúcar
6 personas = x
4x = 6 × 100g
x = 6 × 100 g / 4
x = 150 g de azúcar.
Por 100 g de mantequilla
4 personas = 100 g de mantequilla
6 personas = x
4x = 6 × 100g
x = 6 × 100 g / 4
x = 150 g de mantequilla
Por 50 g de harina
4 personas = 50 g de queso
6 personas = x
4x = 6 × 50g
x = 6 × 50 g / 4
x = 75 g de queso.
Por tanto, la cantidad de ingredientes necesarios para 6 personas es:
450 g de queso, 15 ml de leche, 150 g de azúcar, 150 g de mantequilla y 75 g de harina.
Graham spent a total of $15.05 on 10 apples and a packet of strawberries. If a packet of strawberries cost $2.55, how much did each apple cost? 15.05*10 + 2.55
Answer: $1.25
Step-by-step explanation:
Given
Graham spends a total of $15.05 on 10 apples and a packet of strawberries
Cost of strawberries packet $2.55
Suppose the cost of each apple is x
So, [tex]10x+2.55=15.05[/tex]
On solving
[tex]\Rightarrow10x=15.05-2.55\\\Rightarrow10x=12.5\\\Rightarrowx=\frac{12.5}{10}=\$1.25[/tex]
The cost of each apple is $1.25

Answer:
x = 4
Step-by-step explanation:
Since the rectangles are similar, use a ratio.
15/6 = 10/x
or
6/15 = x/10
I will use 15/6 = 10/x to solve this problem, but both ratios should work to solve this problem.
15/6 = 10/x
Cross Multiply:
6(10) = 15x
Solve:
60 = 15x
x = 4
What is the point-slope equation of a line if the slope is 3 and it passes through the point (-9, 2
Answer:
The point-slope equation of the line is y - 2 = 3(x + 9)
Step-by-step explanation:
The form of the point-slope equation is y - y1 = m(x - x1), where
m is the slope of the line(x1, y1) is a point on the line∵ The slope of a line is 3
∴ m = 3
∵ The line passes through point (-9, 2)
∵ x1 = -9
∴ y1 = 2
→ Substitute the values of m, x1, and y1 in the point-slope form
∵ y - y1 = m(x - x1)
∴ y - 2 = 3(x - (-9))
→ Remember (-)(-) = (+)
∴ y - 2 = 3(x + 9)
∴ The point-slope equation of the line is y - 2 = 3(x + 9)

Step-by-step explanation:
does anyone know how to expand 2 (x + 3)
Answer:
2(x + 3) = 2x + 6
Step-by-step explanation:
Here, we want to expand
2(x + 3)
To do this, we simply multiply the term outside the bracket with each of the terms inside it
That will be;
(2 * x ) + (2 * 3)
= 2x + 6
Mr. Selan loves the 99-cent menu at Wendy's (sadly prices went up a few years ago). He used to buy two chicken sandwich at 99-cents each. With a tax of 8.5%, how much would he pay for the two sandwiches? Round your answer to the nearest cent
Answer:
Mr. Selan would pay $2.15 for the sandwiches with tax.
Step-by-step explanation:
Given that:
Cost of each sandwich = 99 cents
Cost of two sandwiches = 99*2 = 198 cents
Sales tax = 8.5%
Sales tax = [tex]\frac{8.5}{100}*198=16.8\ cents[/tex]
Sales tax = 17 cents
Total cost = 198 + 17 = 215 cents
Total cost = $2.15
Hence,
Mr. Selan would pay $2.15 for the sandwiches with tax.

Solve for x.
A
3x - 6
130°
8x+4
Answer:
x = 12
A = 30
Step-by-step explanation:
Here, we want to solve for the value of x
The angle at the top of the triangle is 8x + 4
The reason for this is because vertically opposite angles are equal
Mathematically;
8x + 4 + 3x - 6 = 130
The reason for this is that opposite interior angles equal the exterior angle
Thus;
8x + 3x + 4- 6 = 130
11x -2 = 130
11x = 130 + 2
11x = 132
x = 132/11
x = 12
The value of A is 3x - 6
A = 3(12)-6
A = 36-6
A = 30
Marla's test scores were 93, 81, 77, and 97. What is Marla's test average?
Answer:
87
Step-by-step explanation:
Hi!
First you add all of the numbers up together:
77+81+93+97= 348
Next, you divide the answer you got above by how many numbers are in your data set:
348/4 = 87
4 because 77,81,93,97 thats four numbers :)
Therefore, Marla's test average is 87!
So anytime you need find the average of any data set, you just add all the numbers together, then divide by the quantity of numbers there are.
