Answer:
$4,370
Step-by-step explanation:
170(21)= $3,570
3,570+800= $4,370
Answer:
x = 4
Step-by-step explanation:
Well, while this is not a full quadratic equation, this can still be worked with, so let's get started.
Taking
, we can simplify this just to make it a bit more professional, to say
(We can do this because of the Symmetric Property of Equality, which states that a=b then b=a).
Now, we can really start by dividing both sides by 6, to get
, and then divide both sides by x to get
.
So, the answer of this quadratic equation is x = 4.
Answer:
16
Step-by-step explanation:
The area of a parallelogram is b * h, where b and h are the base and height respectively. We know the base but not the height. However, we see a right triangle that has the height and 3 as legs and 5 as the hypotenuse. Pythagorean Triples tell us that the height is 4 and the area will be 4 * 4 = 16 sq. units. Hope this helps!
Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in
Answer:
-16/5
Step-by-step explanation:
-16/5 is correct because you need to find out what number times 2 +2/3 equals -86/15. So the answer has to be negative so the bottom numebr has to be 5 because 3x5=15 and the top number is -16 due to multiplcation
