Answer:
x = 70
Step-by-step explanation:
Answer:
Step-by-step explanation:
b/c we know that the inside angles of a triangle add to 180
180 = 38 + x + x + 2
180 = 40 + 2x
140 = 2x
70 = x

Answer:18
4x +108=180
Step-by-step explanation:
Answer:
x=18
Step-by-step explanation:
a straight angle is a total of 180 degrees so you subtract 108 from 180 to get 72 and then divide by 4 to get 18

In the figure below mPUR =77 and mST=74 Find mPR
Answer:
a)
The angle formed by intersecting chords is half of the sum of the intercepted arcs:
1/2(mST + mPR) = m∠PUR1.2(74° + mPR) = 77°74° + mPR = 2*77°mPR = 154° - 74°mPR = 80°b)
The angle formed by two tangents is the half of the difference of the intercepted arcs:
m∠PSR = 1/2(mPTR - mPR)m∠PSR = 1/2(247° - (360° - 247°))m∠PSR = 247° - 180°m∠PSR = 67°In hopes of encouraging healthier snacks at school, Pete brought in a tray of carrot sticks and apple slices to share.

Solve each equation for y (get into slope-intercept/y=mx + b form): a) 10x + 5y = 20 b) 3x - 2y = 10 + 4x
Don't forget to explain how you got the answers.
Answer:
see below
Step-by-step explanation:
We want to solve each equation for y, so y must be alone on one side of the equation.
a) 10x + 5y = 20
Subtract 10x from both sides.
5y = 20 - 10x
Place the x term in front to follow y = mx + b form.
5y = -10x + 20
We want to isolate y completely, so divide both sides by 5. On the right side, be sure to divide each component by 5.
5y/5 = -10/5x + 20/5
y = -2x + 4
This equation is in slope-intercept form.
b) 3x - 2y = 10 + 4x
We can see that y is negative in this original equation. Let's add 2y to both sides to make y positive.
3x = 10 + 4x + 2y
Now we want to isolate y, so subtract 4x from both sides.
3x - 4x = 10 + 2y
Simplify.
-x = 10 + 2y
Isolate y further by subtracting 10 from both sides.
-x - 10 = 2y
Again, we want to isolate y completely, so divide both sides by 2. On the left side, be sure to divide each component by 2.
-x/2 - 10/2 = 2y/2
-1/2x - 5 = y
This looks backwards (although it is in slope-intercept form), so let's rearrange it just to make it more clear.
y = -1/2x - 5
This equation is in slope-intercept form.
Hope this helps!

I got this answer correct on a test
Alejandro compra un terreno de 0,3 hm cuadrados y 0,9 dam al cuadrados ¿cuanto ha pagado por el terreno
Answer:
Si el metro cuadrado es a $ 50 Alejadro pagó por el terreno $195 000
Step-by-step explanation:
Ya que no se especifica un valor por unidad de área podemos suponer por ejemplo $ 50 / metro^2
Terreno:
0.3 hm^2
0.9 dam^2
1) Vamos convertir a la misma unidad de área las áreas del terreno para poder saber su costo.
-Hectómetro cuadrado
1 hm^2 = 10 000 m^2
Por lo tanto,
0.3 hm^2 * 10 000 m^2 / 1 hm^2 = 3000 m^2
-Decámetro cuadrado
1 dam^2 = 1 000 m^2
Por lo tanto,
0.9 dam^2 * 1 000 m^2 /1 dam^2 = 900 m^2
Así que el total del terreno es de 3900 m^2
2) Ahora podemos calcular el valor total del terreno
area* valor (por m^2)
3900 m^2 * $50/ m^2 = $195 000

Enter the
value of p so that the expression
3(n + 5) is equlvalent to (n + p)3
Answer:
p=5
Step-by-step explanation:
a(x+y) is also (x+y)a
So if 3(n+5) has to be equivalent to (n+p)3, then p has to be 5.

Hope it is helpful....21. identify the secant that intersects OA.
=============================================================
Explanation:
A secant line cuts the circle so that part of the line is inside the circle, and the rest (or majority) of the line is outside the circle. In other words, the secant line intersects the circle at exactly two points.
This is in contrast to a tangent line that only touches the circle at exactly one point. Line L is the tangent line in this case.
Segment DC is a diameter of the circle as it goes through the center, and this segments endpoints are on the circle's edge. The segments AD and AC are radii of the circle.

Line BC

What cosine function represents an amplitude of 3, a period of π, no horizontal shift, and a vertical shift of 2? (6 points)
Group of answer choices
f(x) = 3 cos 2x + 2
f(x) = 3 cos πx + 2

We are able to use the transformation formula

. You start with
f

and replace
a
with the desired amplitude,
h
with the desired horizontal shift, and
k
with the desired vertical shift. This leaves out the
b

How much larger is 45 than 10
solve for y. -5(6+7y)= -5(6+y)
Answer:
y = 0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5(6+7y)=−5(6+y)
(−5) (6) + (−5) (7y) = (−5) (6) + (−5) (y) (Distribute)
−30 + − 35y = −30 + −5y
−35y − 30 = −5y −30
Step 2: Add 5y to both sides.
−35y − 30 + 5y = −5y −30 + 5y
−30y −30 = −30
Step 3: Add 30 to both sides.
−30y − 30 + 30 = −30 + 30
−30y = 0
Step 4: Divide both sides by -30.
−30y /−30 = 0 /−30
