SOMEONE PLEASE HELP ME WITH THIS!!!!! ITS GEOMETRY
Answer:
KG = 7 (A)
m KIH = 28 (B)
m JIH = 96 (D)
m HKI = 68 (B)
m KJI = 84 (C)
Step-by-step explanation:
Notice that the triangle HKJ is identical to HIJ. Since there are lines drawn to each other and both triangles are identical, the lines KG and GI are the same. This means that it is 7.
The triangle KGJ is identical with IGH. Using the recognise angle property, we know that angle JKI is the same as KHI. This means that it is 28.
Angle JIH is the same as angle JKH. Since JKH is 180 - (KHI or 84), we know that the angle JIH is 96.
We can find angle HKI by subtracting 96 by 28 because we know that angle HKI is the same as JIH. This gives us 96-2 8 = 68.
Angle KJI is the same as KHI which is 84. Therefore, KJI is also 84.

This diagram shows a right square pyramid and some of its dimensions. What is the volume of the pyramid?
A) 48 cubic inches
B 60 cubic inches
C 144 cubic inches
D) 180 cubic inches
Please I need help :(
Answer:
Volume of square Pyramid is 48 cubic inches.
Option A is correct option.
Step-by-step explanation:
Height of Pyramid = 4 in
Length of Base = 6 in
We need to find volume of square pyramid
The formula used is:
[tex]Volume\: of\: Square\: Pyramid=\frac{1}{3}\times A \times h[/tex]
Where A is area of base and h is height.
[tex]Area\: of\: Base =(Length)^2= 6^2 = 36[/tex]
Now, putting values of A = 36 and h = 5 and finding volume
[tex]Volume\: of\: Square\: Pyramid=\frac{1}{3}\times A \times h\\Volume\: of\: Square\: Pyramid=\frac{1}{3}\times 36 \times 4\\Volume\: of\: Square\: Pyramid=12 \times 4\\Volume\: of\: Square\: Pyramid=48 \: cubic\:inches[/tex]
So, Volume of square Pyramid is 48 cubic inches.
Option A is correct option.

49x2 - 81 is an example of the difference of two
squares. All polynomials that are a difference of two
squares factor in a very specific way. Which of the
following would represent the factorization of a polynomial
that was the difference of two squares.
(x - 25)
(9x – 100)
(25x – 4)(25x – 4)
(x-4) (x-9)
(4x + 3)(4x - 3)
Answer:
(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.
Step-by-step explanation:
Formulas are used to factorize the polynomials.
In the given question, we can see a difference of squares
the difference of squares can be factorized using the formula
[tex]a^2-b^2 = (a+b)(a-b)[/tex]
Here a^2 and b^2 are squares and factorized as sum and difference of numbers.
So in the given options,
(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.

function g(x)=(x-4)2+2?
O-4
O-2
O2
O4
Answer:
-4
Step-by-step explanation:
When we talk of the horizontal translation, we are dealing with a change in the x value
Initially we had x alone while we had x-4 in the second
What this mean is that there is a change of -4
Answer:
Step-by-step explanation:
i put -4 and wrong, pretty sure its 4

Molly's Custom Kitchen Supplies sells handmade forks and spoons. It costs the store $1.70 to buy the
supplies to make a fork and $1.30 to buy the supplies to make a spoon. The store sells forks for $5.60
and spoons for $5.40. Last April Molly's Custom Kitchen Supplies spent $37.90 on materials for forks
and spoons. They sold the finished products for a total of S147.20. How many forks and how many
spoons did they make last April?
Write the equation for the cost of making forks and spoons:
Write the equation that represents the money made from selling forks and
spoons:
They made
forks "type in the number only
They made
spoons *type in the number only
9514 1404 393
Answer:
7 forks20 spoonsStep-by-step explanation:
Let x and y represent the numbers of forks and spoons made, respectively.
The cost of materials is ...
1.70x + 1.30y = 37.90
The revenue from sales is ...
5.60x + 5.40y = 147.20
You can solve these by any of your favorite methods. A graph is attached. It shows the solution is (x, y) = (7, 20).
They made 7 forks and 20 spoons.

The equation coefficients are not "nice" multiples of each other, so elimination and substitution will require multiplying both equations by some numbers. If we're going to that trouble, we may as well use Cramer's Rule or a variation of the "cross multiplication method". The latter is relatively straightforward and can be easy to remember. It tells you the solution to ...
ax +by +c = 0
dx +ey +g = 0
is ...
1/(ae-db) = x/(bg-ey) = y/(cd-ga)
Here, that becomes ...
1/(1.70·5.40-5.60·1.30) = x/(1.30·(-147.20)-5.40·(-37.90))
= y/(-37.90·5.60-(-147.20·1.70))
1/1.9 = x/13.3 = y/38
x = 13.3/1.9 = 7 . . . number of forks
y = 38/1.9 = 20 . . . number of spoons
__
The above solution formula may be more easily remembered in terms of the cross-multiplication pattern that gives the method its name. When the coefficients are written in two rows of four, with the last being a repeat of the first:
a b c ad e g deach of the three denominators (of 1, x, and y) is the difference of products in adjacent columns, formed in an X fashion: ae-db, bg-ec, cd-ga. Note that the equations are written in "general" form, which is similar to "standard" form, but with all of the non-zero terms on the left of the equal sign. (This has the effect of changing the sign of the constants: 1.7x+1.3y=37.9 ⇒ 1.7x+1.3y-37.9=0)
