both of those figures have 6 faces, and 8 edges.
Have a nice day! :-)
Answer:
Each shape has 12 edges
Step-by-step explanation:
Every cube (regular hexahedron) has 6 square faces and each face has 4 edges. However, each edge is shared between 2 faces. So, you can determine how many edges there are by multiplying 6 x 4 and dividing the resulting number (24) by 2, getting the final number of 12.

Answer:
y=2(x + 2))^2 - 9
Step-by-step explanation:
So, whenever two negative signs are right next to each other, they make a positive. However, when they are alone, they stay negative.
With this, y=2(x-(-2))^2 + (-9) --> y=2(x + 2))^2 -9
2x-y=10 y=-4x+2 substitution method
Answers
Answer:
the solution is (2, -6)
Step-by-step explanation:
Substitute the second equation into the first, replacing y in the first:
2x - (-4x+2) = 10
Simplifying, we get:
2x + 4x - 2 = 10, or:
6x = 12, which yields x = 2.
Substituting 2 for x in the second equation yields y = -4(2) + 2 = 0, or y = -6
Then the solution is (2, -6).

In triangle RST, the measure of angle T=90°, the measure of angle R=82°, and TR=44 feet. Find the length of ST to the nearest tenth of a foot.
Answers
Answer:
[tex]x=6.183ft[/tex]
Step-by-step explanation:
From the question we are told that:
Angel of side [tex]T=90[/tex]
Angel of side [tex]R=82[/tex]
Length Side [tex]TR=44[/tex]
Generally the equation for Angle of side ST [tex]\theta[/tex] is mathematically given by
Since Angle in Triangle =180 therefore
[tex]\theta=180-(90+82)[/tex]
[tex]\theta=8[/tex]
Therefore Applying sine rule to get Length of ST x
[tex]\frac{x}{sin\theta}=\frac{TR}{sin82}[/tex]
[tex]x=\frac{44}{sin82}*sin8[/tex]
[tex]x=6.183ft[/tex]

A store has shirts on display. Seven of the shirts are red. There are 5 more blue shirts than green shirts. There are 2 fewer yellow shirts than green shirts. If there are 28 shirts in all, how many shirts are there of each color? Ask for details Follow Report
Answers
Answer:
7 red shirts
6 green shirts
11 blue shirts
4 yellow shirts
Step-by-step explanation:
Let y represent the number of green shirts.
So y+5 is the number of blue shirts.
And y-2 is the number of yellow shirts.
And we have 5 red shirts.
Therefore,
7+5+y+y-2+y=28
12-2+3y=28
10+3y=28
3y=28-10
3y=18,divde through by 3

Sum of 2 fifths of x and 6x and 6 in algebraic expression
Answers
Sum of 2 fifths of x and 6x and 6 in algebraic expression = 2/5 x +6x +6
Answer:
(14x+12)/5
Step-by-step explanation:
2 fifth of x = 2/5 * x= 2x/5
2 fifth of 6x = 2/5 * 6x = 12x/5
2 fifth of 6 = 2/5 * 6 = 12/5
2x/5 + 12x/5 + 12/5
= (2x+12x+12)/5
= (14x+12)/5
What is the surface area of a conical grain storage tank that has a height of 54 meters and a diameter of 18 meters round the answer to the nearest square meter
Answers
Answer:
1803 square meter
Step-by-step explanation:
The surface area of a cone
A=πr(r+V(h2+r2))
where A is the surface area, r is the radius and h is the height
Given that the height of 54 meters and a diameter of 18 meters, the radius is half the diameter hence
radius = 18/2 = 9 m
A = 9π (9 + V(54^2 + 9^2))
= 9π (9 + V2997)
= 9π (9 + 54.74486)
= 1803.068976 Square meters
To the nearest square meter
A = 1803

Answers
The answer is x=-10
Step-by-step explanation:
the reasoning is you do the inverse or opposite of three to both sides so you add +3 to both sides so the -3 and the +3 would cancel out then you would add +3 to the integer -23 and get -20 next is you divide by 2 on each side so you 2÷2 which would cancel out and then -20÷2 which would equal -10
Hence the answer is x=-10
2x + (-3) - (-3) = -23 - (-3)
2x = -23 + 3
2x = -20
2x/2 =-20/2
x = -10
A two-factor between-subjects design is evaluated. The F-value for Factor A has df = 1, 40 and the F-value for Factor B has df = 3, 40. Based on this information, what are the df values for the A x B interaction?
Answers
Answer:
The df values for the A x B interaction are also 3,40
Step-by-step explanation:
The F-value for Factor A has df = 1, 40
The F-value for Factor B has df = 3, 40.
The df values for the A x B interaction are also 3,40
This is because the source of variation between columns has ( c- 1); rc(n-1) degrees of freedom and the source of variation between rows has (r-1); rc(n-1) degrees of freedom and the source of variation of interaction
(between rows and columns) has ( c-1) ( r-1); rc(n-1) degrees of freedom.
Therefore
Factor A: ( c- 1); rc(n-1) = 1,40
Factor B: (r-1); rc(n-1) = 3,40
Interaction : ( c-1) ( r-1); rc(n-1) = 3*1,(40)= 3,40
where c refers to columns , r refers to rows and n refers to the total sample size.
