find the selling price $280 tax 5%
Answer:
The selling price is $294
Step-by-step explanation:
5/100 (280)
0.05 * 280 = 14
5% of 280 equals 14.
To find the selling price we have to add the tax to the price.
$14 + $280 = $294
The selling price is $294
y=-3x+16 y=7 substitution method
Evaluate (18)^2-(15)^2
Please show working.
Answer:
99
Step-by-step explanation:
You can solve it by Squaring/multiply 18 by itself and 15 by itself then subtract them both:
(18 × 18) - (15 × 15)
324 - 225
99
You could also do difference of two squares:
(x² - y²)
= (x + y) (x - y)
= (18 + 15) (18 - 15)
= (33) (3)
= 99
Answer:
99Step-by-step explanation:
Evaluate
= (18)^2-(15)^2
= 324 - 225
= 99

write an equivalent expression for 7^12 * 7^4
The equivalent expression of 7¹² × 7⁴ is 7¹⁶.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
It is a relation of the form y = aˣ in mathematics, where x is the independent variable
We have to determine the equivalent expression for 7¹² × 7⁴
⇒ 7¹² × 7⁴
⇒ 7⁽¹²⁺⁴⁾
⇒ 7¹⁶
Therefore, the equivalent expression of 7¹² × 7⁴ is 7¹⁶.

The shadow of a 5-foot tall post is 10 feet long. At the same time, a tree casts a shadow that is 24 feet long. What is the height of the tree?
A.
14 feet
В.
12 feet
C.
18 feet
D. 2 feet
Answer:
C. 12 feet.
Step-by-step explanation:
The lamp post has a shadow that's twice as long as it'a actual height. The tree's shadow is 24 feet long, so it would be 24/2, which is 12 feet.
0.26 as a fraction? And 0.79 as a fraction?
Answer:
0.26=13/50 0.79=79/100
Step-by-step explanation:
All decimals are over a number in the power of ten. If you say the decimals out loud you would say "26 hundredths " and "79 hundredths" so you place the decimals over 100 and then simplify.
Answer: 12/50 and 79/100

Is it possible to form a triangle using 15 in, 12 in, 8 in ? Why or why not?
Answer:
No
Step-by-step explanation:
Use the pythagoreon theory
15^2+12^2=8^2
454=64
Since they do not equal the same number you can not form a triangle, and no matter how many times you switch the numbers around they will not equal.

Now,
Find the value of x. Draw a triangle and label each interior angle before solving.
Then find the angle measures of the polygon.
Angle one: 2x°, angle two: xº, angle 3: (X + 8)°
Sum of all angles in a triangle = 180°
Which means :-
∠1 + ∠2 + ∠3 = 180°
[tex]2x + x + x + 8 = 180°[/tex]
[tex]4x + 8 = 180°[/tex]
[tex]4x = 180 - 8[/tex]
[tex]4x = 172[/tex]
[tex]x = \frac{172}{4} [/tex]
[tex]x = 43[/tex]
Angle 1 :-
= 2x
= 2 × 43
= 86°Angle 2 :-
= x
= 43°Angle 3 :-
= x + 8
= 43 + 8
= 51°[tex]therefore \: , \: the \: value \: of \: x = 43°[/tex]

Question Says:-An equilateral triangle is a triangle with three equal sides. The perimeter of an equilateral triangle varies directly with the length of one side. What is an equation that relates the perimeter p and length of a side?
Answer:-See, let us consider the sides as l as per question.
And, perimeter as p as per question.
We know that:-
The sum of all the boundary gives us the perimeter of the figure.
It is Equilateral Triangle, so the equation will be:-
[tex]l + l + l = p[/tex]
Now, adding it up, we get
[tex]3l = p[/tex]
So, 3l=p relates the side and perimeter.

Find the slope of the line through the given points. (1,3) and (0,−9)
Thank you so much :)
Answer:
The answer is 12Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(1,3) and (0,−9)
The slope is
[tex]m = \frac{ - 9 - 3}{0 - 1} = \frac{ - 12}{ - 1} = 12 \\ [/tex]
We have the final answer as
12Hope this helps you
The slope of the line would be 12.
