You find a crystal in the shape of a prism. Find the volume of the crystal.
The point Bis directly underneath point E, and the following lengths are known:
• From A to B: 2 mm
• From B to C:3 mm
. From A to F: 6 mm
• From B to E: 10 mm
. From C to D: 7 mm
• From A to G: 4 mm
G

B
What is the area of the base? ( 1 point) Explain or show your reasoning. (2 points)
The Volume of crystals is 160 mm³ while the area of the base is 20 mm².
VolumeVolume is the amount of space occupied by a three dimensional shape or object.
Area of triangle = (1/2) * DF * height
Height = 10 - 6 = 4 mm, DF = AC = AB + BC = 2 + 3 = 5 mm
Area of triangle = (1/2) * 5 * 4 = 10 mm²
Volume of triangle prism = Area of triangle * AG = 10 * 4 = 40 mm³
Volume of rectangular prism = A to F * AC * AG = 6 * 5 * 4 = 120 mm³
Volume of crystals = 120 + 40 = 160 mm³
Area of base = AC * AG = 5 * 4 = 20 mm²
The Volume of crystals is 160 mm³ while the area of the base is 20 mm².

Answer
Club = 7
Diamond = 6
Spade = 2
Heart = 5
Step-by-step explanation
Here it shows that 1 club + 1 diamond + 1 spade is equal to 15. Ok, let's get back to that one later.
In the next hint it shows that 3 clubs equals 21. So, in order to get the value of the club, divide 21 by 3, and you'll get 7. This means that 7 is the value of the club.
Now on to the third hint. Here it shows that 1 diamond plus 2 clubs are equal to 20. We already got the value of the club, which is 7, so add 7+7 and you'll get 14. Then, subtract 14 from 20 and you'll get the value of the diamond, which is 6.
Finally, the fourth hint. Here it shows that 1 diamond + 1 heart + 1 spade = 13. So, inorder to get the value of the heart, add the value of the diamond and the spade, which sums up to 8. Then subtract 8 from 13 and you'll get the value of the heart, which is 5.

y= -5x _
y=-7x-14
—————— (y-y=-5x-(-7x)-14)....
0=-2x-14 => x=-7 => y=-5*(-7)=35
Answer: x = -7 and y = 35
Step-by-step explanation: STEPS USING SUBSTITUTION
y= -5x
y= - 7x - 14
consider the first equation. Add 5x to both sides.
y + 5x = 0
consider the second equation. Add 7x to both sides
y + 7x = -14
to solve a pair of equations using substitution, first solves one of the equations for one of the variables then substitute the result for that variable in the other equation. and so goes on

What is the percent of change from 8 to 4?
Answer:
50% decease
Step-by-step explanation:
A change from 8 to 4 represents a negative change (decrease) of -50%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent = New - Old/Old x 100
Percent = 4-8/8 x 100
Where: 8 is the old value and 4 is the new value. In this case we have a negative change (decrease) of -50 percent because the new value is smaller than the old value.
Hence, 50% decrease
Check Answer:
8 x 50% = 4
8 - 4 = 4
Hence, 50% decrease is the correct answer.

2.((Number × Percent/100)) + Number
((38 × 15/100)) + 38
5.7 + 38
= 43.7
3. I say that Mrs. House should go-to target. And just by $1.30.
At Kohls, the speaker would be at $45.00.
At target, the speaker would be at $43.70.
$45.00 - $43.70 = $1.30

x +423 = 540 . . . simplify
x = 117 . . . . . . . . subtract 117
PLEASE HELP ME Superman can fly on a speed of 20 miles per second Lois Lane is currently 5,000 miles away needs to be saved in exactly 5 minutes will Superman be able to get there in time
Answer:
He will get there in time
Step-by-step explanation:
Superman speed = 20miles per second and there are 60 seconds per minute, so Superman's speed is 1,200 miles per minute
1,200miles/minute * 5 minutes = 6,000 miles
6,000 miles > 5,000 miles so our boi will make it within 5 minutes

Volume of 8 and the product of 5 and q increased by 6 yeilds
88
Answer:
It could be either of two ways:
8
x
+
10
or
8
(
x
+
10
)
Explanation:
The wording is a little unclear because this could be done in two ways:
8
x
+
10
or
8
(
x
+
10
)
The first one is "the product of 8 and a number, increased by 10"
The second is "the product of 8, and a number increased by 10"
The one you might write depends on how you say the statement!
In either case, when you read the phrase "a number" in algebra, you make this the variable - whatever letter you prefer (does not have to be
x
!)
Step-by-step explanation:
The verbal statement of the given algebraic expression gives us; 5(q + 6) = 88
How to write Algebraic expressions?
Now, we are told that the product of 5 and q increased by 6 yields 88. Thus, the expression gives us;
5(q + 6) = 88
Therefore we can conclude and say that the verbal statement of the algebraic expression gives us;
5(q + 6) = 88

find the value of x please help
Answer:
x=37
Step-by-step explanation:
Area of triangle = x+x+x=180
= 78+65+x=180
=143+x=180
=x=180-143 (bring 143 to the otherside)
x=37
In the given figure, We are to find the respective value of x .
Solution :
We know that,
Sum of all the angles of the triangle = 180°
So,
[tex] \qquad \sf \dashrightarrow{ x {}^{ \circ} + 65 ^{ \circ} +78 ^{ \circ} = 180}[/tex]
[tex] \qquad \sf \dashrightarrow{ x ^{ \circ} + 143^{ \circ} = 180^{ \circ}}[/tex]
[tex] \qquad \sf \dashrightarrow{ x ^{ \circ} = 180^{ \circ}} - 143^{ \circ}[/tex]
[tex] \qquad \bf \dashrightarrow{ x ^{ \circ} = 37^{ \circ}}[/tex]
Therefore, The value of x is 37°
