Answer:
809.0
Step-by-step explanation:
Given the exponential function h (t) = 1250(0.865)^t
When t = 3
h(3) = 1250(0.865)^3
h(3) = 1250 (0.6472)
h(3) = 809.0
Hence the value to the nearest tenth is 809.0

Which values from the set {0, 1/2 , 2.5, 4} make the inequality 8g < 4 true?
Answer:
only 0
Step-by-step explanation:
8g < 4 simplifies to g < 4/8, i.e., g < 1/2
only 0 is smaller than 1/2
Help and please make sure the answer is right :)
Answer:
2
Step-by-step explanation:
[tex]131 = 64x + 3[/tex]
subtract [tex]3[/tex] from both sides, to isolate the variable
[tex]128 = 64x[/tex]
divide both sides by [tex]64[/tex]
[tex]x = 2[/tex]

find an expression for the area of a rectangle of sides 2x+3 and x-1 given that the perimeter is 28cm what is the value of x
Answer:
4cm
Step-by-step explanation:
Given data
L=(2x+3)
W=(x-1)
P=28cm
A= L*W
A= (2x+3)*(x-1)
open bracket
A= 2x^2-2x+3x-3
collect like terms
A= 2x^2+x-3
P= 2L+2W
P= 2*(2x+3)+2(x-1)
P= 4x+6+2x-2
collect like terms
P= 6x-4
but p= 28
28= 6x-4
28-4= 6x
24= 6x
x= 24/6
x= 4cm
Hence x= 4cm

Answer:
y=2x−5 is a line
Step-by-step explanation:
Explanation: y=2x−3 is in slope intercept form for a linear equation, y=mx+b , where m is the slope and b is the y-intercept. The y-intercept is the point at which x=0 and y=−3 , which is point (0,−3) You can plot this point on your graph.

A jeweler sells a popular line of charm bracelets. Each bracelet includes one chain and a number of charms selected by the customer. The price of the chain is 25 dollars, and each charm costs c dollars. Which expressions represent the price, in dollars, of a charm bracelet with five charms? Select ALL that apply.
Answer:
Price of bracelet = $(25 + 5c)
Step-by-step explanation:
As given,
A bracelet = 1 chain + Number of charm selected by customer
Also given,
Price of chain = $25
Price of each charm = $c
As,
we have to write equation for a bracelet with 5 charm
So,
Price of bracelet = Price of 1 chain + Price of 5 charm
As
Price of 1 charm = $c
⇒Price of 5 charm = $5×c = $5c
∴ we get
Price of bracelet = $25 + $5c = $(25 + 5c)
Jordan types at a constant rate of 40 words per minute. The number of words typed, is a function of the number of minutes spent typing, Which equation models this situation?
Answer:
[tex]w = 40m[/tex]
Step-by-step explanation:
Given
[tex]Rate = 40\ words\ per\ minute[/tex]
Required
Express as an equation
Represent the number of words with w and the minutes with m.
In 1 minute, Jordan types 40 words.
In m minutes, Jordan will type 40m words.
So, the function is:
[tex]w = 40m[/tex]

Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Classify each angle
Name Each Angle in Four Ways
Answer:
1) Obtuse angle
2) Obtuse angle
3) Acute angle
You can do 4 and 5. I will give you a hint that acute angles are less than 90 degrees and obtuse angles are more than 90 degrees. And if it is a straight line it is 180 degrees.
6) Angle KLM, MLK, Obtuse angle, and angle 5.
7) Angle DCB, BCD, Obtuse angle, and angle 5.
You can do 8. I will give you a hint that the letters will start from end-middle-end and it can be opposite. If getting confused then look what I did. On muber 6, my I typed angle KLM and angle MLK. Both of them are same but look on how I typed. Also while naming angles, they will be in capital.
Hope this helps, thank you !!
Which conclusion does the diagram support?
Answer:
The conclusion supported by the diagram is;
(A) [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]
Step-by-step explanation:
The question is examines the theorem that two transversals cut by three or more parallel lines are proportionally divided by the transversals
The given parallel lines are;
Line CD, line BE, and line line AB
The given transversals are;
Line AC and line DF
Therefore, by the above three or more parallel lines cutting two transversal theorem, we have;
BC/AB = ED/FE, BC/DF = AB/FE, CA/AB = DF/FE
From BC/AB = ED/FE, we find the inverse of both sides to get;
[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{1}{\dfrac{ED}{FE} }[/tex]
[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{AB}{BC} \ and \ \dfrac{1}{\dfrac{ED}{FE} } = \dfrac{FE}{ED}[/tex]
[tex]\therefore \ \dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]
The correct option is [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]

Why is it important to be careful of the order of the two letters used when naming a ray?
Answer:
Because one letter represents an endpoint and the other doesn't.
Step-by-step explanation:
Ray AB starts at endpoint A and goes through point B and then on, indefinitely.
Ray BA starts at endpoint B and goes through point A and then on, indefinitely.
They 'point' in opposite directions.
James wants to buy a house.
The price of the house is a quarter of a million pounds.

The distance from the ladder to the end of the side is 5 ft. The distance from the top of the ladder to the bottom is 13 ft long! HOW TALL IS IT? WILL MARK BRAINLIEST
Answer:
12 ft
Step-by-step explanation:
Note that you have a right triangle here, with hypotenuse 13 ft, and base 5 ft. Using the Pythagorean Theorem, we find the height of the upper tip of the ladder as follows:
(13 ft)^2 = y^2 + (5 ft)^2. Then y^2 = 144 ft^2, and y =height= 12 ft
