person 6-9 MathXL 8th grade question 2
Answer:
<1 = 112degrees
<2 = 33degrees
Step-by-step explanation:
From the figure, the sum of interior angles of the larger triangle is equal to the exterior, hence;
<1 + 15 = 127
<1 = 127 - 15
<1 = 112degrees
For the smaller triangle;
<1 = <2 + 79
112 = <2 + 79
<2 = 112-79
<2 = 33
Hence the measure of <2 is 33degrees
please help me!!!!lol
Answer:
a = 0, b = 7
a = 1, b = 6
a = 2, b = 5
a = 3, b = 4
a = 4, b = 3
a = 5, b = 2
a = 6, b = 1
a = 7, b = 0
Step-by-step explanation:
the sum of a and b must equal 7 because 4 x 7 = 28

Explain which properties you would use to fully expand (the problem in the screenshot)
Answer:
Firs property used : Quotient Property
[tex]log_b(\frac{X}{Y} ) = log_bX -log_bY[/tex]
[tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = log_b(\sqrt[3]{x}) - log_b(36y^2)[/tex]
Second property used : Product Property
[tex]log_b(XY) = log_bX + log_b Y[/tex]
[tex]log_b(\sqrt[3]{x}) - log_b(36y^2) = (log_b(\sqrt[3]{x}) - [log_b36 + log_by^2)[/tex]
Third property used : Power Property
[tex]log_b \sqrt[n]{X} = log_b(X)^{\frac{1}{n}} = \frac{1}{n} log_b X[/tex]
[tex](log_b(\sqrt[3]{x}) - [log_b6^2 + log_by^2) = \frac{1}{3} log_bx - 2log_b 6 - 2log_by[/tex]
Fully expanded form:
[tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = \frac{1}{3} log_b x-2log_b6-2log_by[/tex]
What’s the point of intersection line 1 is 3x-2y=5 and Line 2 is x+2y=7
Answer:
(3,2)
Step-by-step explanation:
3x-2y=5
x+2y=7 Add them up
4x=12 Solve for x
x=3
3+2y=7 Plug it back into either one of the parent functions and solve for y
2y=4
y=2
(3,2) That's the point where the two lines intersect each other.

Answer:
Crossing a land bridge.
Step-by-step explanation:
We that what I think they would do.
1) Solve for Side A.
2) Solve for Angle B.
Best answer will receive Brainliest.
solution given;
let
AB=a
AC=b=30ft
AB=c=20ft
<A=115°
By using Cosine rule.
a²=b²+c²-2bc cos angle
a²=30²+20²-2*30*20 Cos 115°
a²=1807.1419
a=√[1807.1419]
a=42.51
Side A is 42.51ft.
Again
Cos B=[tex] \frac{a²+c²-b²}{2ac} [/tex]
Cos B=[tex] \frac{42.51²+20²-30²}{2*42.51*20} [/tex]
Cos B=0.7687
<B=Cos -¹(0.7687)
<B=39.46°
Angle B is 39.46°
2 x [(27–3) - (3+4)] = n
what’s (n)
Answer:
n = 34
Step-by-step explanation:
2{(24- ( 3 + 4)) =n
2{(24 - 7) =n
2 x 17 = n
34 = n
swap the sides
n = 34
half-life of Po-210 is 140 days. If the initial mass of the sample is 5
kg, how much will remain after 420 days.
Answer:
[tex]0.625kg[/tex]
Step-by-step explanation:
we are given half-life of PO-210 and the initial mass
we want to figure out the remaining mass after 420 days
in order to solve so we can consider the half-life formula given by
[tex] \displaystyle f(t) = a {0.5}^{t/T} [/tex]
where:
f(t) is the remaining quantity of a substance after time t has elapsed.a is the initial quantity of this substance.T is the half-lifesince it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5
thus substitute:
[tex]\displaystyle f(420)=5\cdot{0.5}^{420/140}[/tex]
reduce fraction:
[tex]\displaystyle f(420)=5\cdot{0.5}^{3}[/tex]
By using calculator we acquire:
[tex]\displaystyle f(420)=0.625[/tex]
hence, the remaining sample after 420 days is 0.625 kg
