Answer:
[tex]Area = 20[/tex]
Step-by-step explanation:
Given
[tex]\large A\left(-4,-2\right), \large B\left(1,3\right), \large C\left(4,-2\right).[/tex]
Required
The area
The area of a triangle is:
[tex]Area = \frac{1}{2}|A_x(B_y - C_y) + B_x(C_y - A_y) + C_x(A_y - B_y)|[/tex]
So, we have:
[tex]Area = \frac{1}{2}|-4(3 - -2) + 1(-2 - -2) + 4(-2 - 3)|[/tex]
[tex]Area = \frac{1}{2}|-4*5 + 1*0 + 4*-5|[/tex]
[tex]Area = \frac{1}{2}|-40|[/tex]
[tex]Area = \frac{1}{2}*40[/tex]
[tex]Area = 20[/tex]

Write the expression for 2 added to the product of a number p and 43
Answer:
43p + 2
Step-by-step explanation:
Product of p and 43 = 43p
2 added to the product of p and 43 = 43p + 2
Answer:
Step-by-step explanation:
The product of a number p and 43 means
p * 43 = 43p
And 2 added to the product gives;
43p + 2
However; the expression is 43p + 2.
HELP ASAP !! Which is more, 1 mile or 365 yards?
Answer:
1 mile is longer than 365 yards
Step-by-step explanation:
there are 1,760 yards in a mile
Hi there!
»»————- ★ ————-««
I believe your answer is:
One mile.
»»————- ★ ————-««
Here’s why:
A mile is 1,760 yards. Since the number of yards given in the question, 365, is less than 1,760, a mile would be more than 365 yards. Side note: 365 yards is about 0.2 of a mile.»»————- ★ ————-««
Hope this helps you. I apologize if it’s incorrect.
x + 3 > 70
How do I solve this step by step?
Answer:
x > 67
Step-by-step explanation:
x+3 >70
subtract from each side
x+3-3 > 70 -3
x > 67
Algebra
To solve this, simplify the algebra inequality.
Subtract three from both sides.
x>67
Meaning, x is bigger than 67.
A number between 10 and 100 is 8 times the sum of its digits. If 45 is substracted
from it, the result equals the number formed by interchanging its digit. Find the
number
Answer:
72
Step-by-step explanation:
Let the number be [tex]xy[/tex]
Value of number = [tex]10x+y[/tex]
[tex]10x+y=8(x+y)[/tex]
[tex]10x+y=8x+8y[/tex]
[tex]2x-7y+0........(1)[/tex]
[tex]10x+y-45=10y+x[/tex]
[tex]9x-9y=45[/tex]
[tex]x-y=5............(2)[/tex]
Multiply by [tex]-2[/tex]
[tex]-2x+2y=-10[/tex]
Add to [tex](1)[/tex]
[tex]-5y=-10[/tex]
[tex]y=2[/tex]
[tex]x-y=5[/tex]
[tex]x-(2)=5[/tex]
[tex]x=7[/tex]
Number = 72

In a 30-60-90 special right triangle, if long leg is 5√3 then the short leg = ___, and the hypotenuse is ____
Answer:
short = 5, hypotenuse = 10
Step-by-step explanation:
In a 30-60-90 triangle, the long leg is x√3, the short leg is x, and the hypothenuse is 2x.
As the long leg is 5√3, we can see that x is 5. So, the short leg would be 5 and the hypothenuse would be 2x5, which is 10.

What is the y-intercept of a line that has a slope of 2 and passes through point (8,3)?
1
3
5
11
Answer:
the y intercept is -13
Step-by-step explanation:
First of all we need the line equation so let's find it first :
y = mx + b
y = 2x + b
_______________________________
The line passes through point ( 8 , 3 ) which means if put 8 instead of x the y must equals to 3 :
2(8) + b = 3
16 + b = 3
b = 3 - 16
b = - 13
______________________________
Now we have the equation of the line :
y = 2x - 13
To find the y-intercept we just need to out 0 (zero ) instead of x ; Let's do it :
y = 2(0) - 13
y = 0 - 13
y = - 13
Thus the y-intercept = - 13

Find the value of the term in the arithmetic sequence using an = a^1+ (n-1)d. 3,5,7,9,11, (8th term)
=========================================================
Work Shown:
a1 = 3 = first term
d = 2 = common difference (since we add 2 to each term to get the next one)
Let's compute the nth term.
an = a1 + (n-1)*d
an = 3 + (n-1)*2
an = 3 + 2n-2
an = 2n+1
-----------------------
To check things so far, we can plug in something like n = 2
an = 2n+1
a2 = 2*2+1
a2 = 5
Showing that the 2nd term is 5, which matches with the sequence given to us
Let's check n = 3
an = 2n+1
a3 = 2*3+1
a3 = 7
That matches as well. I'll let you check the others.
-----------------------
Plug in n = 8 to find the 8th term
an = 2n+1
a8 = 2*8+1
a8 = 17
The eighth term is 17, which is the final answer.
-----------------------
You could extend out the given sequence by adding 2 each time until you reach the 8th term
3,5,7,9,11,13,15,17
Though this method is slow if you need to find say the 38th term
Answer:
17 is the answer for the value of the term in the arithmetic sequence using the above

I really need help do can someone do it step by step so I can understand plzzzz
Answer:
4525.2 floz
Step-by-step explanation:
so, we need to calculate the volume of the cylinder.
as with all straight objects, it is simply the base area times is height.
careful - we got the diameter. the radius r is half the diameter. so, r = 20/2 = 10 in
the volume of an object is airways the same, no matter how we orient it. it can be standing up, laying on its side, balancing at an angle, ... - none of that has an impact on the volume (or its surface area).
so, we simply say that the base area is the circle, and we also know the height.
the area of a circle is
Ac = pi×r²
and so, the volume of the cylinder
Vc = pi×r² × height = pi×10² × 26 = pi×2600 =
= 8168.1408993334624201... in³
now, we know that 1 in³ = 0.554 floz
so, now we need to adapt our in³ to floz by using that formula.
be careful with the direction of that adaptation. clearly, 1 floz is more than 1 in³. therefore, the number in floz has to be much smaller than in in³.
so, we know, we multiply our in³ by 0.554.
8168.1408993334624201... × 0.554 =
= 4525.1500582307381807... =
= 4525.2 floz
Mike and Sarah are packing boxes at a factory. Mike packs 30 boxes each hour. Sarah packs 15 boxes each hour. How many boxes will each person have packed after an 8 hour shift?
Answer:
Mike= 240 boxes
Sarah= 120 boxes
Step-by-step explanation:
Mike and Sarah are packing boxes at a company
Mike packs 30 boxes each hour, after an 8 hour shift the number of boxes he will pack is
= 30×8
= 240
Sarah packs 15 boxes each hour, afterr an 8 hour shift the number of boxes she will pack is
= 15×8
= 120
Hence after the 8 hours shift Mike will pack 240 boxes while Sarah will pack 120 boxes
