Convert the rate 30 cm/s to m/h

MrRissso [65]

$1m=100cm\to1cm=\dfrac{1}{100}m\\\\1h=3600s\to1s=\dfrac{1}{3600}h\\\\\\30\dfrac{cm}{s}=30\cdot\dfrac{\frac{1}{100}}{\frac{1}{3600}}\ \dfrac{m}{h}=30\cdot\dfrac{1}{100}\cdot3600\ \dfrac{m}{h}=30\cdot36\ \dfrac{m}{h}=\boxed{1,080\ \frac{m}{h}}\\\\\\Answer:\boxed{30\frac{cm}{s}=1,80\frac{m}{h}}$

Find the value of x. The diagram is not to scale.

Lubov Fominskaja [6]

Answer:

x = 13

Step-by-step explanation:

110° is the vertically opposite angle of one of the interior angles of the given triangle.

Therefore,

$x \degree + 57 \degree + 110 \degree = 180 \degree \\ \\x \degree + 167 \degree = 180 \degree \\ \\ x \degree = 180 \degree -167 \degree \\ \\ x \degree = 13 \degree \\ \\ x = 13$

The trapezoid below has an area of 475 square meters.

OLga [1]

Data:
B (Larger base) = 28 m
b (Minor base) = 18 m
h (height) = ?
A (area) = 475 m²

Formula:
$A = \frac{(B+b)*h}{2}$

Substitute:
$475 = \frac{(28+18)*h}{2}$
$475 = \frac{\diagup\!\!\!\!\!46^{23}*h}{\diagup\!\!\!\!2^1}\:\:\to\:\:\:475 = 23*h\:\:or\:\:\boxed{\boxed{23h = 475}}$

Answer:
$\textcircled{ A } 23h = 475$
