Answer:
Estimate = 600,000
Step-by-step explanation:
An estimate can be defined as a rough calculation of a numerical value, usually the upper limitation.
Given the following numerical values;
212,514
396,705
To add the two values together, we would first of all determine the estimate.
Estimate of 212,514 = 200,000
Estimate of 396,705 = 400,000
Adding the two values;
200,000 + 400,000 = 600,000.
Actual addition of the values would have given;
212,514 + 396,705 = 609,219.
Therefore, 600,000 is an estimated value of 609,219.

Answer:
Step-by-step explanation:
The area of this parallelogram is
A=hb (height times base)
h=A/b, we see A=14.4mi^2 and b=4.8mi so
h=(14.4mi^2)/(4.8mi)
h=3 mi
Solve for x. 5000(2)^x = 3500(3)^x
Answer:
0.887966
Step-by-step explanation:
1. Divide by 3500
(5000/3500)(2^x) = (3^x)
2. divide by 2^x and simplify
10/7 = (3/2)^x.
3. apply 'ln' function
ln(10/7) = xln(3/2)
4. divide ln(3/2)
ln(10/7) / ln(3/2) = x
x = 0.87966
Bean seeds from supplier A have 85% germination rate and those from supplier B have 75% germination rate. A seed-packing company purchases 40% of its seed from A, 60% from B, and mix them together. Find the probability that a seed selected at random from the mixed will germinate.
Answer:
0.79 = 79% probability that a seed selected at random from the mixed will germinate.
Step-by-step explanation:
Probability of a seed germinating:
85% of 40%(from company A)
75% of 60%(from company B)
Then
[tex]P = 0.85*0.4 + 0.75*0.6 = 0.79[/tex]
0.79 = 79% probability that a seed selected at random from the mixed will germinate.
ABC measures 140° and is bisected
by BD. What is mDBC= ?
Answer:
angle abc =140°
and bd bisected by bd so, bd divede angle abc.
angle dbc= angle abc / 2
angle dbc=140°/2
angle dbc=70°
The measure of angle DBC from the given figure is 70°.
The measure of angle ABC is 140°.
What is an angle bisector?The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts.
Angle bisector BD is bisecting angle ABC equally, which is
∠ABC=∠ABD+∠DBC
⇒ 140°=∠DBC+∠DBC
⇒ 2∠DBC=140°
⇒ ∠DBC=70°
Therefore, the measure of angle DBC from the given figure is 70°.

Answer:
x=27
Step-by-step explanation:
Hey there!
the exterior angles of a quadrilateral add up to equal 360
so 360=2x+40+4x+3x+x+50
step 1 combine like terms
2x+4x+3x+x=10x
50+40=90
now we have
360=10x+90
step 2 subtract each side by 90
360-90=270
90-90 cancels out
now we have 270=10x
step 3 divide each side by 10
270/10=27
we're left with
x=27

Answer:
[tex](x,y) =(-4,-3)[/tex] --- Vertex
[tex]x = -4[/tex] --- Axis of symmetry
Step-by-step explanation:
Given
[tex]y = -6(x + 4)^2 - 3[/tex]
Solving (a): The vertex
For an equation written in
[tex]y = a(x - h)^2 + k[/tex]
The vertex is:
[tex](x,y) = (h,k)[/tex]
By comparison:
[tex]y = a(x - h)^2 + k[/tex] and [tex]y = -6(x + 4)^2 - 3[/tex]
[tex]-h =4[/tex] [tex]k = -3[/tex]
[tex]h =-4[/tex] [tex]k = -3[/tex]
So, the vertex is:
[tex](x,y) =(-4,-3)[/tex]
Solving (b): The axis of symmetry
For an equation written in
[tex]y = a(x - h)^2 + k[/tex]
The axis of symmetry is:
x = h
In (a):
[tex]h =-4[/tex]
So:
[tex]x = -4[/tex]

m=(y2-y1)/(x2-x1), we have points (-3,-6) and (2,-2) so
m=(-2-(-6))/(2-(-3))
m=4/5 or 0.8 so our line is now
y=0.8x+b, using point (2,-2) we can solve for b
-2=0.8(2)+b
-2=1.6+b
b=-3.6 so the line is
y=0.8x-3.6 which can also be expressed as
y=4x/5-18/5

Destiny bought a carton of orange juice. She drank 1/3 of the carton on Monday and 5/12 of the carton on Tuesday. What fraction of the carton did Destiny drink?
A. 6/12 Carton
B. 9/12 Carton
C. 6/15 Carton
D. 1 Carton
Answer:
B
9/12 carton
Step-by-step explanation:

7 Romeo and Juliet first saw each other when they were 270 feet apart.
Romeo began running toward Juliet at a rate of 16 ft/s. At the same
moment, Juliet began running toward Romeo at a rate of 14 ft/s.
A. How many seconds after they started running will they meet?
B. How far will Romeo have run then?
Answer:
A: 9 seconds
B: 144 ft.
Step-by-step explanation:
A:
Let t = no. of seconds for them to meet
When they meet the sum of their distances is 270 ft, dist = rate * time
16t + 14t = 270
30t = 270
t = 270/30
t = 9 seconds
B:
He ran 9 sec at 16 ft/sec, therefore:
9 * 16 = 144 ft
