Answer:
JK = 18.8
Step-by-step explanation:
7/33 = 4/JK
132 = 7JK
JK = 18.86
Answer:
JK=18.8
Step-by-step explanation:
so we are given that ΔGHI ~ ΔJKL
GI~JL (because corresponding parts of similar triangles are similar)
so GI/JL=ratio of similitude=7/33
GH~JK (corresponding parts of similar triangles are similar)
and GH/JK=ratio of similitude
so:
GH/JK=GI/JL
subsitute known values
4/JK=7/33
cross multiply
7JK=132
divide
JK=132/7
simplify and round
JK≈18.8

What is the standard form of the nymber 6.7321 * 108?
A. 6,732,100,000
B. 673,210,000
C. 67,321,000
D. 6,732,100
Answer:
673,210,000
Step-by-step explanation:
The given number is :
N = 6.7321 × 10⁸
We need to write it into the standard form.
10⁸ = 100000000
It can be calculated as follows :
6.7321 × 100000000 = [tex]\dfrac{67321 }{10000}\times 100000000[/tex]
= 673,210,000
So, the standard form of the given number is 673,210,000. Hence, the correct option is (c).

The picture (attached) shows two isosceles right triangles, so the altitude marked x splits the bottom side in half, 4 units and 4 units.
Each triangle is a right triangle with one leg of length 4, hypotenuse 6. Use the Pythagorean Theorem (leg)^2 + (leg)^2 = (hypotenuse)^2.

Determine whether the set of lengths could form a triangle.
5, 2, and 3.
Answer:
Determine whether the set of lengths could form a triangle 5, 2 and 3. No it can not form a triangle.
Step-by-step explanation:
5 + 2 is greater than 3. 5 + 3 is greater than 2. 3 + 2 is not greater than 5
Answer:
No, the set of lengths - 5, 2 and 3 will not form a triangle.
Step-by-step explanation:
As we know,
The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
[tex]5 + 2 > 3[/tex]
[tex]3 + 5 > 2[/tex]
[tex]2 + 3 = 5[/tex]

is 10x-5=8x-2x + 7 -2 equivalent?
Answer:
2.5
Step-by-step explanation:
Lets simpify one side first
8x - 2x + 7 +2
8-2 = 6
so 6x
7-2 = 5
6x+9
10x - 5 = 6x +5
(You add 5 due to it being negative on the other side)
+5 +5
10x= 6x +10
-6x -6x
4x = 10
Divide each side by 4
x = 2.5 or 10/4 or 5/2
Answer: No
Step-by-step explanation: To find whether these are equivalent, we first need to simplify the equation on the right.
8x-2x+7-2
8x-2x+5 (work- 7-2 = 5)
6x+5 (work- 8x-2x=6x) These are like terms, so we can subtract them
now that we have simplified, let's write the equations once again.
10x-5=6x+5
they are surely not equivalent

3(2z + 3)
= -75
I need help ty
Answer:
= − 1 4
Step-by-step explanation:
Answer:
z = - 14
Step-by-step explanation:
Solving for z using basic algebra
3(2z + 3) = -75
Step 1 distribute the 3
3 * 2z = 6z
3 * 3 = 9
now we have 6z + 9 = -75
step 2 subtract 9 from each side
9 - 9 cancels out
-75 - 9 = -84
now we have 6z = - 84
step 3 divide each side by 6
6z / 6 cancels out
-84 / 6 = -14
we're left with z = -14
Rewrite 8*8*8*8 using an exponent
Answer:
8⁴
Step-by-step explanation:
8*8*8*8 =8⁴
8 exponent 4
Answer:
[tex]8^{4}\\[/tex]
Step-by-step explanation:
An exponent describes how many times the base is repeatedly shown. For instance:
6³
6 is the base and 3 is the exponent. Because the exponent is 3, the base is repeated that many times. Here's what I mean:
6² = 6 (6) (6)
So in 8 (8) (8) (8), the base would be 8 and this is repeated 4 times. So the exponent would be 4.
So your answer would look like [tex]8^{4}[/tex].

Maria is in charge of making punch for the party she adds two quarts of water to 1 quart of orange juice and 2 quarts of mango juice then she adds one quart of crushed strawberry juice and 2 quarts of pineapple juice to the mixture how many quarts of punch does Maria make?
Answer:
8 quarts
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Water = 2 quarts
Orange Juice = 1quarts
Mango Juice = 2 quarts
Strawberry juice = 1 quart
Pineapple Juice = 2 quarts
So, Total mixture = Sum of all ingredients in quarts
= 2 + 1 + 2 + 1 + 2 = 8 quarts
Hence, Maria makes 8 quarts of punch.

if x varies directly as y and x=3 when y=15 find the value of x when y=25
Answer:
Step-by-step explanation:
x=5
Answer:
x is 5.
Step-by-step explanation:
X varies directly with y, so we can use the equation x = yk (with k standing for the constant of variation) to find what the constant is. Substitute 3 for x and 15 for y
3 = 15k
Now divide both sides by 15.
3/15 = k
3/15 simplifies to 1/5.
1/5 = k
Now that we know the constant, then what we need to do is find 1/5 of 25 to get x.
1/5(25) = x
Multiply 1/5 by 25 to get 5.
5 = x
The problem is solved.
X will be 5 in this scenario.

You don't need complex numbers to solve this, but if you try to find a and b you will need complex numbers.
Step-by-step explanation:
a+b = 2
a*b = 3
1/a + 1/b = x
(a*b)*(1/a + 1/b) = (a*b)x
b + a = (a*b)(x)
2 = 3x
x = 2/3
b = 2 - a
a*(2 - a) = 3
-a^2 + 2a = 3
-a^2 + 2a - 3 = 0
a^2 - 2a + 3 = 0
let's solve the quadratic equation
a^2 - 2a + 3 = a^2 - 2a + 1 + 2 = (a - 1)^2 + 2 = 0
(a - 1)^2 = -2
[tex]a_1 - 1 = \sqrt{2}i\\a_1 = 1+\sqrt{2}i\\\\a_2 - 1 = -\sqrt{2}i\\a_2 = 1 - \sqrt{2}i\\[/tex]
these options correspond to a and b from the original question.
Segment AB, with endpoints A(-6,9) and B(12, -3), is dilated by a scale factor of 2/3 centered at the origin.
What are the coordinates of A'?
Enter your answer as an ordered pair, using parentheses and a comma, like this: (42,53)
The coordinates of A' after the dilation is (-4,6)
How to determine the coordinates of A'?The given parameters are:
A = (-6,9)
B = (12, -3)
Scale factor, k = 2/3
The coordinates of A' is then calculated as:
A' = A * k
This gives
A' = (-6,9) * 2/3
Evaluate the product
A' = (-4,6)
Hence, the coordinates of A' after the dilation is (-4,6)

What is the area of the polygon? Show your work.
Answer:
33 square units
Step-by-step explanation:
Assuming that each line on this grid increases by a value of one, the area of the polygon can be determined by breaking it down into a large rectangle and two smaller triangles.
Area of the rectangleThe area of a rectangle is simply [tex]A = bh[/tex], where b represents the base and h represents the height.
Counting the size of each side, we can determine that they are 6 units for the base and 4 units for the height.
Substituting in the values, we get:
[tex]A = (6)(4)\\A = 24[/tex]
The area of the rectangle is 24 square units
Area of the trianglesThe area of a triangle is simply [tex]A = \frac{1}{2} bh[/tex].
The base of each triangle is 3, and the height of each triangle is also 3.
Substituting in the values, we get:
[tex]A = \frac{1}{2} (3)(3)\\A = \frac{1}{2} (9)\\A = 9 / 2\\A = 4.5[/tex]
The area of each triangle is 4.5 square units
Area of the polygonTo get the area of the polygon, we simply add up the area of the rectangle and both triangles
[tex]A = 24 + 4.5 + 4.5\\A = 24 + 9\\A = 33[/tex]
The total area of the polygon is 33 square units.
