Find the length of DF or state what additional information you would need to find it.
Answers
Answer:
DF=3.75
Step-by-step explanation:
24/6=15/x
cross multiply to get 24x=90
x=3.75
The length of side DF will be 5 units.No more additional information would need to find, all the information is already given.
What is the congruent triangle?Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
All the given information is shown in the figure attached.
Since the two triangles are congruent the ratio of their sides is equal,
BC / EF = AC / EF
Suppose the length of side DF is x.
20/DF=24 /6
20/x = 24 / 6
x = 20 / 4
x=5
DF = 5 units
Thus, the length of side DF will be 5 units.No more additional information would need to find, all the information is already given.

Answers
Answer:
option 3, 45
Step-by-step explanation:
3x - 9° + 30° + 24° = 180° (angle sum property of a triangle)
3x - 9° + 54° = 180°
3x + 45° = 180°
3x = 180° - 45°
3x = 135°
x = 135/3
x = 45°
therefore, option 3 is the correct option
Which set of ordered pairs represents a function? (1 point)

B) {(0, 0), (1, 2), (2, 6), (2, 8)}
C) {(0, 0), (0, 2), (2, 0), (2, 4)}
D) {(0, 2), (1, 4), (2, 6), (3, 6)}
Answers
Explanation: a function can be described as something that has only one output for each input. So an X or input can only have ONE output.
Ex. (2,6) (2,8) would NOT be a function because there are two 2’s with two different outputs meaning it’s not a function.

Answers
Hello!
[tex]\large\boxed{\text{n = 5, m = 9, x = 512}}[/tex]
An exponential expression in form [tex]\sqrt[z]{x^{y} }[/tex] can be rewritten as [tex]x^{\frac{y}{z} }[/tex] where "z" is the root and "y" is the power. For example:
[tex]x^{\frac{2}{3} } = \sqrt[3]{x^{2} }[/tex].
We can apply this idea to this problem:
[tex](32)^{\frac{9}{5} } = (\sqrt[5]{32^{9} } )[/tex]
Therefore:
n = 5
m = 9
Simplify the expression:
[tex]\sqrt[5]{32^{9} } = (\sqrt[5]{32} )^{9}[/tex]
[tex]\sqrt[5]{32} = 2\\\\2^{9} = 512[/tex]
Therefore, the values of all letters are:
n = 5
m = 9
x = 512
Answer:
n=5
m=9
x=512

A company sells two electronics packages. Package A contains 4 printers and 9 computers and costs $10,100 Package B contains 10 printers and 30 computers and costs $36,000
Answers
Answer:
y = $1433.33
x = -$700
Step-by-step explanation:
Since we are not asked what to find, we can as well find the price of each package.
Let x be the price of one printer
Let y be the price of one computer.
If Package A contains 4 printers and 9 computers and costs $10,100, this is expressed as;
4x + 9y = 10,100 ..... 1
If Package B contains 10 printers and 30 computers and costs $36,000, this is expressed as;
10x + 30y = 36,000
x + 3y = 3600 ...... 2
Solve equation 1 and 2 simultaneously
From 2; x = 3600 - 3y ..... 3
Substitute 3 into 1;
From 1;
4x + 9y = 10,000
4(3600-3y) + 9y = 10,100
14400 - 12y + 9y = 10100
14400 - 3y = 10100
-3y = 10100 - 14400
-3y = -4300
y = 4300/3
y = $1433.33
Substitute y = 1433.3 into 2;
From 2: x+3y = 3600
x + 3(1433.33) = 3600
x+4300 = 3600
x = 3600 - 4300
x = -$700

Which expression represents "4 times the sum of x and 7"
Answers
Answer:
4 (x + 7)
Step-by-step explanation:
Answer:
4(x+7)
Step-by-step explanation:
First, start with the terms x and 7, the expression calls for their sum so addition is the needed operation. Then, 4 times the sum means that 4 must be multiplied after x and 7 are added. So because of PEMDAS parentheses are needed around x+7. Therefore the expression is 4(x+7).

Charlotte's curtain company is making curtains for a local hotel. She wants each curtain to be 36 inches long. At the fabric store, fabric is sold by the foot. If Charlotte's curtain company wants to make 53 curtains, how many feet of fabric will she need?
Answers
Answer:
159 feet of fabric
Step-by-step explanation
We are told that 1 curtain is 36inches long
Since 1 foot = 12inches
x foot = 36inches
Cross multiply;
12 * x = 36
12x = 36
x = 36/12
x = 3
Hence 36inches is same as 3 feet
If Charlotte's curtain company wants to make 53 curtains, the length of 53 curtain is expressed as;
1 curtain = 3feet
53 curtain = y
y = 53 *3
y = 159 feet
Hence she will need 159 feet of fabric

If DH = (4x + 10) in. and HI = (2x − 4) in., then x =_______ , HI =_______ , and ID = _________
Answers
i think the answer will be 6.
Answer:
x = -7
HI = -18
ID = -36
Step-by-step explanation:
I'm guessing that H is the midpoint, so that would mean DH = HI.
So plug in.
4x + 10 = 2x - 4 (subtract 2x on both sides)
2x + 10 = -4 (subtract 10 on both sides)
2x = -14 (divide by 2 on both sides)
x = -7
PLUG IN TO GET ID because DH + HI = ID
4(-7) + 10 + 2(-7) - 4 (simplify)
-28 + 10 -14 - 4 (collect like terms)
-46 + 10 = -36
ID = -36
HI = 2(-7) -4 (simplify)
HI = -14 -4
HI = -18
