Step-by-step explanation:

\begin{array}{ccc}1&-&d\\2&-&c\\3&-&a\\4&-&b\\5&-&f\\6&-&e\end{array}

Value 1:

r = 5ft, h = 10ft. Substitute:

SA=2\pi(5)(10)+2\pi(5^2)=100\pi+50\pi=150\pi\ ft^2

Value 2:

r = 2in, h = 4in. Substitute:

V=\dfrac{1}{3}\pi(2^2)(4)=\dfrac{1}{3}\pi(4)(4)=\dfrac{16\pi}{3}\\\\\pi\approzx3.14\to V\approx\dfrac{(16)(3.14)}{3}\approx16.75\ in^3

Value 3:

r = 6m. Substitute:

V=\dfrac{4}{3}\pi(6^3)=\dfrac{4}{3}\pi(216)=4\pi(72)=288\pi\ m^3\\\\\pi\approx3.14\to V\approx288(3.14)=904.32\ m^3

If 3/5 of the certain length is 210m then 5/7 of length is​
Mamont248 [21]

Answer:

250 m

Step-by-step explanation:

Let the total length be x m.

\therefore \:  \frac{3}{5}  \times x = 210 \\ x = 210 \times  \frac{5}{3}  \\ x = 70 \times 5 \\ x = 350 \: m \\  \\  \frac{5}{7}  \times x =  \frac{5}{7}  \times 350 = 5 \times 50 = 250 \: m

X^2-7x+10=(x-5)(x- )what’s the missing number
Lena [83]

Answer:

(x - 2)

Step-by-step explanation:

Given the quadratic

x² - 7x + 10

To factor consider the factors of the constant term ( + 10) which sum to give the coefficient of the x- term ( - 7)

The factors are - 5 and - 2 since

- 5 × - 2 = + 10 and - 5 + (- 2) = - 7, thus

x² - 7x + 10 = (x - 5)(x - 2)
