The ratio of solid beads to clear beads in a vase is 820. Select all the correct statements that tell if the operations will give an equivalent ratio.
A) Add 2 solid and 2 clear beads.
B) Subtract 8 solid and 6 clear beads.
C) Multiply the number of solid and clear beads by 2.
D) Divide the number of solid and clear beads by 4.
E) Multiply the number of solid and clear beads by 18.
Answer:
C, D and E
Step-by-step explanation:
Given
Represent solid beads with S and clear beads with C
So:
[tex]S:C = 8:20[/tex]
Required
Select operations that give an equivalent ratio
First, we need to get the unit ratio
[tex]S:C = 8:20[/tex]
Divide through by 4
[tex]S:C = 2:5[/tex] -- This means that, after any operation. The equivalent ratio must be 2: 5
Option A: Add 2 to S and 2 to C
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8 + 2 : 20 + 2[/tex]
[tex]S:C = 10 : 22[/tex]
Divide through by 2
[tex]S:C = 5:11[/tex]
Option B: Subtract 8 from S and 6 from C
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8 - 8 : 20 - 6[/tex]
[tex]S:C = 0 : 14[/tex]
Option C: Multiply S and C by 2
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8*2:20*2[/tex]
[tex]S:C = 16:40[/tex]
Divide through by 8
[tex]S:C = 2:5[/tex]
Option D: Divide S and C by 4
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8/2:20/4[/tex]
[tex]S:C = 2:5[/tex]
Option E: Multiply S and C by 18
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8*18:20*18[/tex]
[tex]S:C = 144:360[/tex]
Divide through by 72
[tex]S:C = 144/72:360/72[/tex]
[tex]S:C = 2:5[/tex]
From the calculations above, options C, D and E gave an equivalent of 2:5.
All of the angles of Triangle ABC measure 60 o. AB = 3x – 4, BC = 4x – 12 and CA = 5x – 20.
Solve for x and find the length of AB.
Answer:
The length of AB is 20 units
Step-by-step explanation:
The equilateral triangle is the triangle that has 3 equal sides and 3 equal angles, the measure of each angle is 60°
∵ All of the angles of triangle ABC measure 60 °
→ By using the fact above
∴ Triangle ABC is an equilateral triangle
→ That means its 3 sides are equal
∴ AB = BC = CA
∵ AB = 3x - 4
∵ BC = 4x - 12
∵ CA = 5x - 20
→ Equate 2 of them to find x
∵ BC = CA
∴ 5x - 20 = 4x - 12
→ Subtract 4x from both sides
∵ 5x - 4x - 20 = 4x - 4x - 12
∴ x - 20 = -12
→ Add 20 to both sides
∴ x - 20 + 20 = -12 + 20
∴ x = 8
→ To find AB substitute the value of x in its expression
∵ AB = 3x - 4
∴ AB = 3(8) - 4
∴ AB = 24 - 4
∴ AB = 20
∴ The length of AB is 20 units

What is the volume of a cone with a radius of 5 inches and a height of 12 inches? (Use 3.14 for .)
942 cubic inches
314 cubic inches
376.8 cubic inches
125.6 cubic inches
Answer:
The height of the cone-shaped cup is 6 inches and the diameter at the top is 3 inches. ... To find the volume of the cone, you use a formula similar to that of a pyramid, ... \begin{align*}V & = \frac{1}{3} \pi r^2 h \\ V & = \frac{1}{3} (3.14)(5^2 )(7) ... The answer is the volume of the cone is 183.16 cubic inches.

what is the rate of change of the function
enter as a fraction
marking brainlist
Answer:
The rate of function is: 5/2
Step-by-step explanation:
As we know that the rate of change of a function is a ratio that compares the difference between the output values to the difference between the corresponding input values
rate of change = change in y-values / change in y-values
So, all we need is to find the slope between any two points as the slope is basically termed as the rate of change.
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-5,\:18\right),\:\left(x_2,\:y_2\right)=\left(-3,\:23\right)[/tex]
[tex]m=\frac{23-18}{-3-\left(-5\right)}[/tex]
[tex]m=\frac{5}{2}[/tex]
Thus, the rate of function is: 5/2
Find the area, in square units, of ️ABC
Answer:
52 square units
Step-by-step explanation:
For this you need the length of CB and the length of DA.
|CB| = √(10²+2²) = 2√26
|DA| = √(10²+2²) = 2√26
area of ABC = base · height / 2 = 2√26 · 2√26 / 2 = 52
find the surface area of this cylinder using pie.
Answer:
the surface area of a cylinder:
[tex]A=750\pi[/tex] ft²
or
[tex]A\approx 2356.19[/tex] ft²
Step-by-step explanation:
Given
r = 10 fth = 15 ftUsing the formula to determine the surface area of a cylinder:
[tex]A=2\pi rh+2\pi r^2[/tex]
[tex]A=2\cdot \pi \cdot 15\cdot 10+2\cdot \pi \cdot 15^2[/tex]
[tex]A=750\pi[/tex] ft²
or
[tex]A\approx 2356.19[/tex] ft²
Thus, the surface area of a cylinder:
[tex]A=750\pi[/tex] ft²
or
[tex]A\approx 2356.19[/tex] ft²

Given g(x)=4-2(3-x), what is the value of g(1)
Answer:
g(1) = 0
Step-by-step explanation:
To evaluate g(1) , substitute x = 1 into g(x), that is
g(1) = 4 - 2(3 - 1)
= 4 - 2(2)
= 4 - 4
= 0

La piscina llena tendra 600.000 litros de agua.Para el tratamiento inicial hay que añadir 10 gramos de cloro por cada 1.000 litros de agua.Si el cloro se vende en botes de 1 kilo.¿cuantos botes necesitaran Sara y sus abuelos?
Answer:
Sara y sus abuelos necesitarán 6 botes.
Step-by-step explanation:
Primero, tienes que encontrar los gramos de cloro que necesitas para 600.000 litros de agua usando una regla de tres dado que sabes que se debe añadir 10 gr de cloro por cada 1.000 litros de agua:
1.000 litros → 10 gr
600.000 litros → x
x=(600.000*10)/1.000=6.000 gr de cloro
Ahora, tienes que encontrar a cuántos kg equivalen los 6.000 gr de cloro que necesitas teniendo en cuenta que 1 kg son 1.000 gr:
1 kg → 1.000 gr
x ← 6.000 gr
x=(6.000*1)/1.000= 6 kg
Finalmente, para saber cuántos botes se necesitan tienes que dividir los 6 kg entre 1 kg porque el cloro se vende en botes 1 kg:
6/1=6
De acuerdo a esto, Sara y sus abuelos necesitarán 6 botes.

The cost of one pound of bananas is greater than $0.41 and less than $0.50. Sarah pays $3.40 for x pounds of bananas. Which inequality represents the range of possible pounds purchased? 0.41 < 0.41 less than StartFraction 3.40 over x EndFraction less than 0.50. < 0.50 0.41 < 0.41 less than StartFraction x over 3.40 EndFraction less than 0.50. < 0.50 0.41 < 3.40x < 0.50 0.41 < 3.40 + x < 0.50
Answer:
0.41 x < 3.40 < 0.50 x
If there is a whole number of pounds it could be: x = 8 pounds
0.41 * 8 = 3.28, 0.50 * 8 = 4
3.28 < 3.40 < 4
Answer:
Inequality is
0.41 x < 3.40 < 0.50 x
