solve for k. a/b=b/a+1k
Answer:
[tex]\frac{(a+b)(a-b)}{ab}[/tex]
Step-by-step explanation:
[tex]\frac{a}{b}=\frac{b}{a} +k[/tex]
[tex]k=\frac{a}{b}-\frac{b}{a}=\frac{a^2-b^2}{ab}=\frac{(a+b)(a-b)}{ab}[/tex]
The side lengths of a rectangle are all multiplied by 5. What happens to its perimeter?
Answer:
The perimeter is multiplied by 5.
Step-by-step explanation:
Perimeter of a rectangle:
The perimeter of a rectangle with sides l and w is given by:
[tex]P = 2(l + w)[/tex]
The side lengths of a rectangle are all multiplied by 5.
This means that [tex]l = 5l, w = 5w[/tex]. So
[tex]P_M = 2(5l + 5w) = 2*5(l+w) = 10(l + w)[/tex]
What happens to its perimeter?
The rate is:
[tex]\frac{P_M}{P} = \frac{10(l+w)}{2(l+w)} = 5[/tex]
The perimeter is multiplied by 5.
What is the perimeter of the track, in meters? Use tt 3.16 and round to the nearest hundredth of a meter
Answer:
The perimeter of the track is of 317 meters.
Step-by-step explanation:
Perimeter:
The perimeter of a figure is the sum of all its dimensions.
In this question:
The track is composed by two straights of 80m, and two half circles with a diameter of 50m.
Perimeter of a circle:
The perimeter of a circle with diameter d is of:
[tex]P = \pi d[/tex]
Track:
Two half circles, each with a diameter of 50m, plus two straight lines of 80m. So
[tex]P = \frac{2\pi}{2}(50) + 2*80) = 50\pi + 160 = 50*3.14 + 160 = 317[/tex]
The perimeter of the track is of 317 meters.

A cylinder has a radius of 5 m and a height of 11 m. Identify the volume of the cylinder to the nearest tenth.
Answer:
86,405 cm³
Step-by-step explanation:
V = cross-sectional area × height = πr²h = 3.142 × 5² × 1100cm
= 86,405 cm³
Answer:
863.9 m³
Step-by-step explanation:
Cylinder volume is V = πr²h. Here the height, h, is 11 m and the radius, r, is 5 m. Thus we have:
V = π(5 m)²(11 m), or
V = π(275) m³, or approximately 863.9 m³

Amelia purchased a new mattress when it was on sale. The sale price was 25% less than the regular price. If the sale price was $481, what was the original price? (Round your answer to the nearest dollar).
Answer:
$641
Step-by-step explanation:
Let $p be the original price.
[tex](1 - 25\%)p = 481 \\ \frac{75}{100} p = 481 \\ p = 641[/tex]
p = 641 (cor. to the nearest dollar)
∴ The original price was $641.

5% of 24 = 1.2
2.4 + 1.2= 3.6
This means she is saving $3.60 because 15% of $24 is $3.60! :)
Jana save $3.6 to buy a shirt.

Pls answer its khan academy I really need it
Answer:
Step-by-step explanation:
Note the f(0) = 9
and f(1) = 15
Since, f(x) = abˣ substituting for x, we get:
9 = f(0) = a . b⁰ = a
⇒ a = 9
Now, f(1) = 15
⇒ 15 = a . b¹
⇒ 15 = 9 . b
⇒ b = 15/19
Therefore,
f (r) = 9. (5/3)
Hence, the answer.
