3 five eights subtracted by 5 four eights.

dmitriy555 [2]

Answer: -1 7/8

Turn 3 5/8 into an Improper Fraction

Multiply 3*8 and get 24. Now add 15 and get 39 (Denominator stays the same). 3 5/8 = 39/8

Turn 5 4/8 into an Improper Fraction

Multiply 5*8 and get 40. Now add 4 and get 44 (Denominator stays the same). 5 4/8 = 44/8

Subtract

39/8 - 44/8 = -15/8

Turn -15/8 into a Mixed Number

-15/8 = -1 7/8

Find the angle between the given vectors to the nearest tenth of a degree.

pochemuha

$\bf \textit{angle between two vectors }\\ \quad \\
cos(\theta)=\cfrac{u \cdot v}{||u||\ ||v||} \implies \cfrac{\text{dot product}}{\text{product of magnitudes}}\\ \quad \\\\
\theta = cos^{-1}\left(\cfrac{u \cdot v}{||u||\ ||v||}\right)\\\\
-----------------------------\\\\
\theta=cos^{-1}\left[ \cfrac{\ \textless \ 8,4\ \textgreater \ \quad \cdot \quad \ \textless \ 9,-9\ \textgreater \ }{(\sqrt{8^2+4^2})(\sqrt{9^2+(-9)^2})} \right]$

$\bf \theta=cos^{-1}\left[ \cfrac{(8\cdot 9)+(4\cdot -9)}{(\sqrt{64+16})(\sqrt{81+81})} \right]\implies \theta=cos^{-1}\left[ \cfrac{36}{(\sqrt{80})(\sqrt{162})} \right]
\\\\\\
\theta=cos^{-1}\left[ \cfrac{36}{(\sqrt{80})(\sqrt{162})} \right]\implies 
\theta=cos^{-1}\left[ \cfrac{36}{\sqrt{12960}}\right]
\\\\\\
\theta=cos^{-1}\left[ \cfrac{36}{36\sqrt{10}}\right]\implies \theta\approx 71.565^o$

on a blueprint, the height of a door is 0.4cm. the actual height of the door is 2m. What is the scale on the blueprint?

Roman55 [17]

Step-by-step explanation:

2 m corresponds to 0.4 cm on a blueprint.

so,

2 m / 0.4 cm = 200 cm / 0.4 cm

our fun the point of view of the blueprint

0.4 cm / 200 cm

the scale on a map or blueprint is usually normed to one unit on the blueprint :

0.4/200 × f/f = 1/(200×f)

0.4 × f = 1

f = 1/0.4 = 2.5

so, our scale is

(0.4 × 2.5) / (200 × 2.5) = 1 / 500

that means 1 cm on the blueprint corresponds to 500 cm or 5 m in reality.

At the school carnival, Jade has a game booth with a spinner. The banner at her booth reads "80% chance of winning!" What is the

Vesnalui [34]

Hi there!

»»————-　★　————-««

I believe your answer is:

20%

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

The banner reads that there is an 80% chance of winning a prize.

⸻⸻⸻⸻

$100\% - 80\% = \boxed{20\%}$

⸻⸻⸻⸻

There is a 20% chance that the player would not win.

Hope this helps you. I apologize if it’s incorrect.
