Question 1(Multiple Choice Worth 1 points)

Mathematics
1 answer:
Artist 52 [7]3 years ago
5 0

The value is 3

Step-by-step explanation:

To simplify the expression -\frac{3}{4} \div \frac{2}{-8}, we can reciprocal the term \frac{2}{-8} to \frac{-8}{2} and multiply, so that we can easily simplify the terms.

Thus, the expression becomes,

-\frac{3}{4} \times \frac{-8}{2}

Multiplying the terms, we get,

\frac{24}{8}

Dividing the terms,

\frac{24}{8}=3

Thus, the value of the expression is 3.

Rhonda had $300 to buy supplies for the animal shelter. She bought 8 bags of dog food and 11 leashes. Each bag of food cost $25.
Readme [11.4K]

Answer:

47.33

Step-by-step explanation:

Hey there! I'm happy to help!

We have 8 bags of dog food and each costs $25.19

8(25.19)=201.52

And we have 11 leashes each costing $4.65.

11(4.65)=51.15

We add these totals up.

201.52+51.15=252.67

We subtract this from 300 to see how much is left.

300-252.67=47.33

Rhonda had $47.33 left after her purchases.

Have a wonderful day! :D

Ratio comparing 12 yds to 12 in is? __:1
const2013 [10]
I'm pretty sure the answer is 3:1 because there are 36 inches in three yard and if you simplified 36:12, it would be 3:1.

Good luck my man.

Answer:

Answer:

safe speed for the larger radius track u= √2 v

Explanation:

The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.

Also given that r_1= smaller radius

r_2= larger radius curve

r_2= 2r_1..............i

let u be the speed of larger radius curve

now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

r

mv

mu

................ii

form i and ii we can write

v^2= \frac{1}{2} u^2v

=

u

⇒u= √2 v

therefore, safe speed for the larger radius track u= √2 v
