Answer:
x = 5/4
Step-by-step explanation:
16x / 16 = 20 / 16
x = 5/4
Answer:
x = 5/4 or 1.2
Step-by-step explanation:
20/16 can be simplified to a smaller fraction, which is 5/4 because 20 and 16 have a common multiple of 4. 5/4 turned into a decimal is 1.2.

Triangle ABC is shown with its inscribed circle drawn. The measure of angle ECF is 72 degrees. What is the measure of angle EGF? Explain or show your reasoning.
Answer:
108°
Step-by-step explanation:
CB and CA are tangents to the circle at points E and F respectively. GE and GF are radii of the circle with center G.
Since, radii of a circle are perpendicular to the tangents at the point of contacts.
[tex] \therefore GE \perp CB\\\\
\& \:GF \perp CA\\\\
m\angle GEC =m\angle GFC = 90\degree \\\\[/tex]
In quadrilateral GECF, by interior angle sum property:
[tex] m\angle C + m\angle E + m\angle F + m\angle EGF = 360\degree \\\\
\therefore 72\degree + 90\degree + 90\degree + m\angle EGF = 360\degree \\\\
\therefore 252\degree + m\angle EGF = 360\degree \\\\
\therefore m\angle EGF = 360\degree - 252\degree \\\\
\therefore m\angle EGF = 108\degree \\[/tex]
Answer:
108°Step-by-step explanation:
Since GE ⊥ BC and GF ⊥ AC,∠GEC = ∠GFC = 90°Sum of 4 angles is 360°, therefore:
∠ECF + ∠EGF = 360° - 180°∠EGF = 180° - 72° ∠EGF = 108°if 3/4 = x/8, then x is equal to

Answer: ∠1 = 77; ∠3 = 41; ∠5 = 41; ∠6 = 92; ∠9 = 103; ∠12 = 47; ∠14 = 103; ∠17 = 41
because of 2 parallel lines
=> ∠1 = ∠10 = 77°
∠7 = ∠12 = 47°
∠16 = ∠7 + ∠6 = 139° ⇒ ∠6 = 139° - ∠7 = 92°
have: ∠7 + ∠6 + ∠5 = 180° ⇒ ∠5 = 180° - (∠7 + ∠6) = 180° - 139° = 41°
∠10 + ∠14 = 180° ⇔ ∠14 = 180° - ∠10 = 103°
∠14 = ∠9 = 103°
∠3 = ∠5 = ∠17 = 41°

Answer:
(d) see below
Step-by-step explanation:
Since each grid square is 1/4 unit. the coordinates in terms of grid squares are ...
A(0.50, -1.25) ⇒ (0.50/.25, -1.25/.25) = (2, -5) . . . grid squares
Point A is located 2 squares right and 5 squares down on the grid. This matches choice D.

I believe it's D

Write an equation of the line that is perpendicular to 2x +4y = 6 and passes through the point (6,4)
Answer:
B
Step-by-step explanation:
let equation be y = mx + b.
2x + 4y = 6
1/2x + y = 3/2
y = -1/2x + 3/2
since perpendicular, their gradients produced equals neg 1.
so,
m = -1/(-1/2) = 2
sub (6, 4):
4 = 2(6) + b
b = -8
therefore, eqn is y = 2x - 8

After all of the start-up costs, a company starts with $100 and makes $0.75 on each unit sold. Write a linear equation in slope intercept form that models this situation using P for profit and N for number of units sold.
A). p=100n+75
B). n=100p+75
C). p=0.75n+100
D). n=0.75p+100
If you guys could help me I would greatly appreciate it!!
The answer would most likely be c because you multiply 0.75 by the amount of units sold and find out the profit after adding it.
Hope this helps! :)

An observation tower is 75 m high. A support wire is attached to the tower 20 m from the top. If the support wire and the ground form an angle of 46 degrees, what is the length of the support wire, to the nearest thousandth?
Answer: 76.46 m
Step-by-step explanation:
Height of tower = 75m
Support wire 20 m from top
Angle formed (α) = 46°
Using Pythagoras :
Sinα = opposite / hypotenus
Height used = height of tower - 20 m from top
Height = opposite = (75 - 20)m = 55m
Hypotenus = Length of support wire
Sin 46 = 55m / hypotenus
Hypotenus * sin 46 = 55
0.71934 * hypotenus = 55
Hypotenus = 55/0.71934
Hypotenus = 76.458976
Hence, Lenght of support wire = 76.46 m

How to determine the remainder in dividing the polynomial P(x) by a divisor x-1?
Answer:
Calculate P(1)
Step-by-step explanation:
Given
P(x)
[tex]Divisor = x - 1[/tex]
Required
How to determine the remainder
First, you equate the divisor to 0 to solve for x
i.e.
[tex]x - 1 = 0[/tex]
[tex]x = 1[/tex]
Next, substitute 1 for x in P(x)
Then solve for P(1)
Take for instance;
If
[tex]P(x) = x^3 - x^2 - 1[/tex]
Substitute 1 for x
[tex]P(1) = 1^3 - 1^2 - 1[/tex]
[tex]P(1) = 1 - 1 - 1[/tex]
[tex]P(1) = - 1[/tex]
Hence, the remainder is -1
After raining for 3/4 of an hour, a rain gauge is 2/5 filled. If it continues to rain at that rate for 15 more minutes, what fraction of the rain gauge will be filled?
To help answer this question, Diego wrote the division equation 3/4 ÷ 2/5 = ?. Explain why this equation does not represent the situation.
Number of minutes in 3/4 of an hour is :
n = 3/4 × 60 = 45 minutes.
Now, If it continues to rain at that rate for 15 more minutes :
So, time taken = 45 + 15 min = 1 hour.
Let, rain gauge is filled x fraction in 1 hour.
So,
[tex]\dfrac{3}{4}x = \dfrac{2}{5}\times 1\\\\x = \dfrac{8}{15}[/tex]
Hence, this is the required solution.

Answer:
that is a great question, could u explain more? im serious
Step-by-step explanation:
Answer:
The large squares represent X squared, and had two sides, blue and red, to determine whether it is positive or negative (blue = positive, red = negative). There is also the long rectangles that represent X, with the positive side being green and the negative red. The side length of X is the same side length of X squared, which makes sense because X multiplied by X equals X squared. The smallest square pieces represent the number 1. The colours are yellow for positive and red for negative. These are the basic pieces used in algebra tiles. Hope this helps
