No, even numbers can be divided by 2. 0 is an even number because zero divided by two equals zero.

Mandy has 50 yards of fabric to make costumes for a play. She makes 12 skirts that take 3 yards each, and 9 hats that take 1 yar

Otrada [13]

50 yards. You are going to be taking away from that 50, so "50 -" should be part of the expression. This eliminates C.

12 skirts that take 3 yards each means 3 yards * 12 skirts which is 3 * 12. This is being subtracted from 50.
We also want to subtract 9 hats * 1 yard which is 9 * 1 = 9

Our expression will look like this: 50 - 12 * 3 - 9 * 1
or 50 - 12 * 3 - 9, which is D

$\\ \sf\longmapsto \dfrac{(0.0225)^{\frac{-3}{2}}\times (0.0001)^{\frac{3}{4}}}{(0.0125)^{\frac{1}{3}}}$

$\\ \sf\longmapsto \dfrac{((0.15)^2)^{\frac{-3}{2}}\times ((0.1)^4)^{\frac{3}{4}}}{(0.5)^3)^{\frac{1}{3}}}$

$\\ \sf\longmapsto \dfrac{(0.15)^{2\times \dfrac{-3}{2}}\times (0.1)^{4\times \dfrac{3}{4}}}{(0.5)^{3\times \dfrac{1}{3}}}$

$\\ \sf\longmapsto \dfrac{(0.15)^{-3}(0.1)^3}{(0.5)^1}$

$\\ \sf\longmapsto \dfrac{\dfrac{1}{(0.15)^3}\times 0.001}{0.5}$

$\\ \sf\longmapsto \dfrac{\dfrac{1}{0.003375}(0.001)}{0.5}$

$\\ \sf\longmapsto\dfrac{ \dfrac{1000000}{3375}\times \dfrac{1}{1000}}{0.5}$

$\\ \sf\longmapsto \dfrac{\dfrac{1000}{3375}}{0.5}$

$\\ \sf\longmapsto \dfrac{1000}{3375}\times \dfrac{10}{5}$

$\\ \sf\longmapsto \dfrac{2000}{3375}$

$\\ \sf\longmapsto 0.592$

Answer:

Option (2). x = 20°

Step-by-step explanation:

In the figure attached,

ΔABC is an equilateral triangle.

By the property of equilateral triangle, all sides of the triangle are equal and measure of all angles of the triangle is 60°.

By this property,

m∠B = 60°

and y = 46 - 16 = 30

By applying Sine rule in ΔBCD,

$\frac{\text{sin}60}{BD}=\frac{\text{sin}80}{46}=\frac{\text{sin}(\angle CBD)}{DC}$

$\frac{\text{sin}80}{46}=\frac{\text{sin}(\angle CBD)}{y}$

sin(∠CBD) = $\frac{30\times \text{sin}80}{46}$

= 0.6423

m∠CBD = 39.96

≈ 40°

m∠ABD = 60° - 40°

= 20°

Therefore, Option (2). 20° will be the answer.

H(x)=17, x=?<br> H(x)=5x+2<br> I don't know how to find x?

Andreas93 [3]

Answer:

• If h(x) is 17, equate the whole function to 17

${ \tt{5x + 2 = 17}} \\ \\ { \tt{5x = 17 - 2}} \\ \\ { \tt{5x = 15}} \\ \\ { \boxed{ \tt{x = 3}}}$
