Answer:
[tex]b=\sqrt{\frac{3V}{h}}[/tex]
Step-by-step explanation:
To solve a formula for one of its variables do that
Underline the variableSeparate it on one side and the other terms on the other sideMake its coefficient equals 1Let us use these steps to solve our question
∵ V = [tex]\frac{1}{3}[/tex] b²h
→ Underline b
∴ V = [tex]\frac{1}{3}[/tex] b²h
→ Multiply both sides by 3 to cancel the denominator on the right side
∴ 3V = b²h
→ Divide both sides by h to move it to the other side
∴ [tex]\frac{3V}{h}=b^{2}[/tex]
→ To find b take √ for both sides
∴ [tex]\sqrt{\frac{3V}{h}}=\sqrt{b^{2} }[/tex]
→ The square root will cancel the power 2 of b
∴ [tex]\sqrt{\frac{3V}{h}}=b[/tex]
→ Switch the two sides
∴ [tex]b=\sqrt{\frac{3V}{h}}[/tex]

Answer:
Slope = 1
Equation: y= 1x + 1 or y= x + 1
Step-by-step explanation:
The slope is one because the rise over run from point (-1,0) to (0,1) is 1/1, and 1/1 is equal to 1. This means in the form y=mx + b the slope would be put in for m. y= 1x + 1. The plus one is because the line crosses the y axis at y = 1. When you are writing the equation technically you do not need to write it as y= 1x +1 you can just do y = x + 1 because there is only 1 x.

4.5(8-x)+37=103-2.5(3x+24)
Answer:
x= -10
Step-by-step explanation:
Answer:
If i did it right...im not sure if i did...but it should be: - 2.5 = x
Step-by-step explanation:
4.5 (8 - x) +37 = 103 - (7.5x + 60)
(36 - 4.5x) + 37 = 103 - (7.5x + 60)
+ 4.5x + 4.5x
36 + 37 = 103 - (12x + 60)
73 = 103 - (12x + 60)
- 103 - 103
-30 = -12x - 60
+ 60 + 60
30 = - 12x
/-12 /-12
- 2.5 = x

The ratio of children to adults at a play is 2:3. The ratio of children under 10 to those over 10 is 7: 3. What % are younger children?
Answer:
28%
Step-by-step explanation:
Let number of children be 2x, then number of adults be 3x
Total number is 5x
Let number of children under 10 be 7y, number of children be 3y,
then total number of children is 10y
so 2x = 10y, x = 5y, y/x = 1/5
younger children = children under 10, number is 7y
so the % is 7y/5x = 7/5 * y/x = 7/5 * 1/5 = 7/25 = 28/100 = 28%

If x equals 8 - (-2.25) and y equals 6 - 4.2 - (-4.9), what is the value of x - y?
Answer:
3.55
Step-by-step explanation:
This is simply combining like terms.
First, lets evaluate the terms separately.
x = 8 - (-2.25)
x = 8 + 2.25 (Negative signs cancel out)
x = 10.25 (Combine like terms)
y = 6 - 4.2 - (-4.9)
y = 6 - 4.2 + 4.9 (Negative signs cancel out)
y = 6.7 (Combine like terms)
Now, lets plug in these values to x - y.
(10.25) - (6.7)
3.55
The value of x - y is equal to 3.55.
Based on the information in the table, is the cost of the apples proportional to the weight of apples?
A pound of apples:
2
3
4
5
Cost of apples:
$3.76
$5.64
$7.52
$9.40
Answer:
I think it is the 3.76 I am 85%sire
Answer:
YEAH IT IS :D
Step-by-step explanation:
First you need to get 1 pound. 2 pounds is 3.76 divide it by 2 and get 1.88. Multiply it by so you can get 3 pounds: 1 x 3 = 3 pounds. 1.88 x 3 is 5.64. Now to get 4 pound you add 1.88 again to 3 pounds to add a pound and you get 7.52. Now add 1.88 to 4 one more time to get 5 pounds: 4 + 1 = 5 pounds. And 7.52 + 1.88 = 9.40. Now you checked the whole table and they are right so yes it is proportional to the weight of apples!

my answer was ( -7, 2 )
The options are
A. ( - infinity, 2)
B. (-7, -2)
C. [ - 7, infinity)
D. ( -7, 2)
Answer:
The answer should be A. [tex]x \in (-\infty,\, 2)[/tex].
Step-by-step explanation:
Start with the second inequality, which is more straightforward than the first. Add [tex]3[/tex] to both sides of this equation to separate [tex]x[/tex] from the numbers:
[tex]x - 3 + 3 \le -1 + 3[/tex]. The direction of the inequality sign shall stay the same.
[tex]x \le 2[/tex].
On the other hand, simplifying the first inequality takes a bit more work. Start by dividing both sides by [tex](-3)[/tex]. However, keep in mind that dividing or multiplying both sides of an inequality with a negative number will invert the direction of the inequality sign. For example, the left-hand side of an inequality might have been greater than the right-hand side. When both sides are multiplied with a number less than zero, the new left-hand side would become smaller than the new right-hand side.
Because [tex](-3)\![/tex] is a negative number, dividing both sides of the first inequality inequality by [tex](-3)[/tex] will turn the "greater-than" sign into a "less-than" sign.
The inequality used to be:
[tex]-3\, (x + 2) > 15[/tex].
After dividing both sides by the negative number [tex](-3)[/tex], it becomes:
[tex]\displaystyle \frac{(-3)\, (x + 2 )}{(-3)} < \frac{15}{(-3)}[/tex].
[tex]\displaystyle (x + 2) < -5[/tex].
[tex]x < -7[/tex].
The question connected the two original inequalities with "or". Therefore, the conditions will be satisfied as long as either of at least one of the two inequalities is true. Note, that [tex]x < 2[/tex] is true whenever [tex]x <-7[/tex] is true. Therefore, any real number that is smaller than [tex]2[/tex] will meet the requirements- not just those that are smaller than [tex](-7)[/tex].
The corresponding interval will be [tex](-\infty,\, 2)[/tex].

How do I find the value of X
Answer:
x = 12
Step-by-step explanation:
ΔABC is a right triangle, therefore we can use Pythagoras' Theorem to find the value of x.
Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Therefore,
a = xb = 16c = 20Substitute these values into the equation and solve for x:
⇒ x² + 16² = 20²
⇒ x² + 256 = 400
⇒ x² = 400 - 256
⇒ x² = 144
⇒ x = √(144)
⇒ x = ±12
As length is positive, x = 12 units (only)

Solve the equation 3/5(x-10)=18-4x-1
Answer:
x=5
Step-by-step explanation:
pls heart and give brainliest
1. Simplify both sides of the equation
3/5 (x−10) = 18 − 4x − 1 ( 3/5 )(x) + ( 3/5 ) (−10) = 18 + − 4 x + − 1 (Distribute)
3/5x + − 6 = 18 + − 4x + − 1 3/5 x − 6 = (−4x) + (18+−1) (Then Combine Like Terms)
3/5 x−6=−4x+17 3/5 x−6=−4x+17
2. Add 4x to both sides
3/5 x−6+4x=−4x+17+4x 23/5 x−6=17
3. Add 6 to both sides
23/5 x−6+6=17+6 23/5 x=23
Step 4: Multiply both sides by 5/23.
( 5/23 )*( 23/5 x)=( 5/23 )*(23)
x = 5
Therefore the answer to this equation is "x = 5"

A cylinder has a height of 17 centimeters and a radius of 15 centimeters. What is its volume?
Use 3.14 and round your answer to the nearest hundredth.
Answer:
Volume of the cylinder is 12016.5 cm³[tex] \\ [/tex]
Step-by-step explanation:
Using formula:
[tex] \: \: \: \: \: \: \: \: \: \: {\underline{\boxed {\pmb{ \sf{Volume \: of \: cylinder = \pi r^2h}}}}} \: \pink\star [/tex]
[tex] \\ [/tex]
Where,
Height of cylinder is 17 cmRadius of the cylinder is 15 cm.Value of π = 3.14[tex] \\ [/tex]
Substituting the required values in the above formula :
[tex] \\ [/tex]
[tex] \dashrightarrow \sf \: \: Volume = 3.14 \times {(15)}^{2} \times 17 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: Volume = 3.14 \times 225 \times 17 \\ \\ [/tex]
[tex]\dashrightarrow \sf \: \: Volume = 706.5 \times 17 \\ \\ [/tex]
[tex]\dashrightarrow~~{\boxed {\pink{\pmb{\sf {Volume = 12016.5 \: {cm}^{3}}}}}} \\ \\ [/tex]
Hence,
Volume of cylinder is 12016.5 cm³Answer :
12000 cm³⠀
Explanation :
We know,
[tex]{ \longrightarrow \qquad{\boldsymbol {\pmb{ Volume_{(cylinder)} = \pi {r}^{2} h \: }}}}[/tex]
Where,
r is the radius of the cylinder. Here, the radius is 15 cm . h is the height of the cylinder. Here, height is 17 cm Here, we will take the value of π as 3.14 approximately .⠀
Substituting the values in the formula :
[tex]{ \longrightarrow \qquad{ { \sf{ Volume_{(cylinder)} = 3.14 \times ({15})^{2} \times 17 \: }}}}[/tex]
⠀
[tex]{ \longrightarrow \qquad{ { \sf{ Volume_{(cylinder)} = 3.14 \: \times 225 \times 17}}}}[/tex]
⠀
[tex]{ \longrightarrow \qquad{ { \sf{ Volume_{(cylinder)} = 3.14 \times 3825 }}}}[/tex]
⠀
[tex]{ \longrightarrow \qquad{ \pmb{ \sf{ Volume_{(cylinder)} = 12010.5 }}}}[/tex]
⠀
Therefore,
The volume of the cylinder is 12000 cm³ . (Rounded to nearest hundredth)A rectangular prism with a volume of 10 cubic units is filled with cubes with side length of 1/2 unit
We know that:
[tex]1. \space\ V_{Rectangular \space\ prism} = 10 \text\] units^{3}\\\\2. \space\ L_{Small \space\ cube} = \frac{1}{2} \space\ units\\\\ 3. \space\ V_{Small \space\ cube} = L ^{3}[/tex]
Step-1: Find the volume of the small cube.
[tex]V_{Small \space\ cube} = L ^{3}[/tex]
[tex]V_{Small \space\ cube} = (\frac{1}{2}) ^{3}[/tex]
[tex]V_{Small \space\ cube} = (\frac{1}{2}) (\frac{1}{2}) (\frac{1}{2})[/tex]
[tex]V_{Small \space\ cube} = \frac{1}{8} \space\ units^{3}[/tex]
Step-2: Divide.
[tex]\frac{10}{\frac{1}{8} }\\\\ \Rrightarrow(10)(8)\\ \\ \Rrightarrow 80[/tex]
Hence, 80 cubes can be fit in the rectangular prism.
volume of rectangular prism = 10 units³
volume of each cube = [tex]\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2} = \frac{1}{8} units^3[/tex]
required cubes = [tex]\frac{10}{ \frac{1}{8} }= 80[/tex]
