Answer:

Total distance = 5 miles

Step-by-step explanation:

Given:

Total time for drive = 10 min = 10 / 60 = 1/6 hour

Time for stop = 5 min

Speed = 30 miles pr hour

Find:

Total distance

Computation:

Total distance = Speed × time

Total distance = 30 × (1/6)

Total distance = 5 miles

Answer:

So a ratio of 8:3 means for every 8 cars that is 3 trucks so we have the number of trucks which is 21 so what i did to find the answer was see how many times 3 went into 21 which is 7 times then you would take the 7 and times it by 8 and get 56 so there are 56 cars.

Answer:    \bold{y=\dfrac{1\pm \sqrt{4x+13}}{2}}

<u>Step-by-step explanation:</u>

Inverse is when you swap the x's and y's and solve for y:

y+\dfrac{13}{4}=\bigg(x-\dfrac{1}{2}\bigg)^2\\\\\\x+\dfrac{13}{4}=\bigg(y-\dfrac{1}{2}\bigg)^2\rightarrow \text{(swapped the x's and y's)}\\\\\\\sqrt{x+\dfrac{13}{4}}=\sqrt{\bigg(y-\dfrac{1}{2}\bigg)^2}\rightarrow \text{(took square root of both sides)}\\\\\\\sqrt{\dfrac{4x+13}{4}}=\pm \bigg(y-\dfrac{1}{2}\bigg)}\rightarrow \text{(created common denominator in radical)}\\\\\\ \dfrac{\sqrt{4x+13}}{2}=\pm \bigg(y-\dfrac{1}{2}\bigg)}\rightarrow \text{(simplified radical)}

\pm \dfrac{\sqrt{4x+13}}{2}=y-\dfrac{1}{2}}\rightarrow \text{(divided both sides by}\ \pm )\\\\\\\dfrac{1}{2}\pm \dfrac{\sqrt{4x+13}}{2}=y\quad \rightarrow \text{(added}\ \dfrac{1}{2}\ \text{to both sides)}\\\\\\\dfrac{1\pm \sqrt{4x+13}}{2}=y\quad \rightarrow \text{(combined numerators)}

Evaluate. Write your answer as a fraction in simplest form.<br><br> 2 1/6 −(−8/3)+(−4 7/9)
Snezhnost [94]

Answer:

1/18

Step-by-step explanation:

first, you make the fraction a mixed number so 2 2/3.

second, the two minuses cancel each other out so 2 1/6 + 2 2/3

third, make the 2/3 from 2 2/3 into 4/6 so you can add it to the 2 1/6

fourth, add your 2 1/6 and your 2 4/6 to get 4 5/6.

that’s the first part: 2 1/6 -(-8/3) is equal to 4 5/6

then, since you’re adding a negative number, it’s basically subtracting the 4 7/9 from 4 5/6

first you subtract the whole numbers = 0

then, make the denominators the same: (6*9, common denominator is 54) so since you’re multipling the 9 from 7/9 by 6, also multiply the 7 by 6 to get 42. 42/54. do the same but with a 9 on the 5/6. you get 45/54

so now you can do 42/54 — 45/54 to get 3/54

54/3 is 18 so you can simplify to 1/18
