The volume of the dilated Prism B is about 10 31/32 ft³
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The height of Prism A is 6 1/2 ft, and The height of Prism B is 3 1/4 ft.
The dilation factor = 3 1/4 ft. ÷ 6 1/2 ft = 0.5
Volume is the product of three sides.
The volume of prism B = Volume of prism A * (dilation factor)³ = 87 3/4 ft³ * (0.5)³ = 10 31/32 ft³
The volume of the dilated Prism B is about 10 31/32 ft³

10 y + 4 = 0
A) x - y=0
C) -y=-4
B) y=-4
D) x + y = 0
Answer:
B) y = -4
Step-by-step explanation:
When rearranging an equation we divide, multiply, subsract, add the same things to both sides of the equation.
So here we would - 4 from both sides to give:
y + 4 - 4 = 0 - 4
This would simplify to:
y = -4
Judy and Amna are on a safari. They are standing 20 feet apart when they spot a snake. Judy and Amna run in opposite directions at speeds of 180 feet per minute and 120 feet per minute, respectively. In how many minutes will they be 2420 ft apart?
Using proportions, it is found that Judy and Amna will be 2420 ft apart after 8 minutes.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
They run in opposite directions, at speeds of 180 feet per minute and 120 feet per minute, respectively, hence each minute they get 180 + 120 = 300 feet apart.
They already are 20 feet apart, so they will need to get more 2420 - 20 = 2400 ft apart. Hence:
1 minute - 300 ft apart.
x minutes - 2400 ft apart.
Applying cross multiplication:
300x = 2400
x = 8.
Judy and Amna will be 2420 ft apart after 8 minutes.

circle A has a diameter of 9 cm. Circle b has a radius of 5 cm
Which circle has the larger circumference ?explain your reasoning
About how many centimeters larger is it?explain your reasoning
Answer:
Circle B has a larger circumference.
Step-by-step explanation:
Circumference of a circle is the diameter times pi.
C = pi•d
Circle B has radius 5, so its diameter is 10. Circle A has diameter of 9. A larger diameter will give a larger circumference.
C_circle A = 9pi
~= 28
While,
C_circle B = 10pi
~= 31
Circle B's circumference is about 3 cm larger. More accurately it's 1pi larger.

Answer:
Option D
Step-by-step explanation:
Hello!
Recall the quadratic equation: [tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex]
Remember that a quadratic equation is written in the form [tex]ax^2 + bx + c\\[/tex]
So:
a = 2b = 5c = -1Plug the values in and solve:
[tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}\\\\x = \frac{-5\pm\sqrt{5^2 - 4(2)(-1)}}{2(2)}$\\\\x = $\frac{-5\pm\sqrt{25 +8}}{2(2)}$\\\\x = $\frac{-5\pm\sqrt{33}}{4}[/tex]
This would be [tex]\boxed{\text{Option D}}[/tex]
The angles in a triangle are in the ratio 1:2:3.
a) Show that the triangle is a right-angled triangle.
Answer:
Step-by-step explanation:
Remark
The angles can measure
x + 2x + 3x
The total must be 180 degrees because all triangles have 180 degrees
Equation
x + 2x + 3x = 180 Combine
6x = 180 Divide by 6
6x/6 = 180/6
x = 30
1x = 30
2x = 60
3x = 3*30 = 90
A right angle triangle has 90 degrees.
Josephine is constructing a circle circumscribed about triangle XYZ. She uses the following sequence of steps to construct the circle.
1. She constructs the perpendicular bisectors of two sides.
2. She finds their point of intersection, P.
3. She uses a compass, with the fixed end on X, to draw a circle passing through point P.
Did Josephine make any errors while constructing the circle?
OA. Yes, she should have placed the compass with the fixed end on P and drawn a circle through point x.
OB. No, she did not make any errors.
OC.
Yes, she should have constructed the angle bisectors.
ज
OD.
Yes, she should have found the perpendicular bisectors of all 3 sides.
Answer:
A
Step-by-step explanation:
there is not much more to say.
the point where actually all 3 line bisectors intersect, is also called the "circumcenter". I guess you understand what that means : it is the center of the circle circumscribing the whole triangle (passing through all 3 corners/vertices).
once you find that point with 2 line bisectors, there is no need to construct the third - it WILL intersect the others at the same point.

Three sisters, whose average age is 10, all have different ages. When they get together in pairs, the average ages of two such pairs are 11 and 12. What is the age of the eldest sister?
The age of the eldest sister is 16 years.
What is an equation?An equation is used to show the relationship between two or more variables and numbers.
Let x represent the age of the older sister and y, z represent the other sisters ages.
Three sisters, whose average age is 10, all have different ages. Hence:
(x + y + z)/3 = 10 (1)
Also, When they get together in pairs, the average ages of two such pairs are 11 and 12, hence:
(x + y)/2 = 11 (2)
(x + z)/2 = 12 (3)
From equation 1, 2 and 3:
x = 16, y = 6, z = 8
The age of the eldest sister is 16 years.
