Which fractions are equivalent to -1/5 ? Choose all answers - 4

Answers

Answer 1
Answer: ok so remember
negative/negative=positive
positive/positive=positive
positive/negative=negative
negative/positive=neative

we have

which are equalivilent to -1/5
negative/positive=negative
we want 2 different signs on top and bottom aka the fraction is negative

cross out -4/-20



ok so a property of equal fractions are
if a/b=c/d, then (a*d)/(b*c)=1
ie
if 1/2=4/8, then 1/2 times 8/4=8/8=1 so

-1/5 times -25/5=25/25=1
they are equal

-1/5 times 10/-2=-10/-10=1
they are equal

-1/5  times 25/-10=-25/-50=1/2,
noe equall


5/-25 and -2/10 are equal
Answer 2
Answer:

Your answer is 5/-25 and -2/10 because -1/5 is -0.2 and 5/-25 gives you -0.2 and -2/10 also gives you -0.2 but you also have -10/25 which gives you 0.4 therefor your answer would be 5/-25 and -2/10

hope this helped

A laboratory technician can clean 34 pipettes every hour with an automatic washer. How many can he clean in 12 minutes? (Hint: Both time periods must be in the same unit of measurement)

Answers

Answer: 6.8

Step-by-step explanation:

34 in 60 minutes

In 12 minutes = ( 12/60) * 34

Answer:

7

Step-by-step explanation:

you can do a ratio where you have 34 over 60 then cross multiply that ratio with x over 12 and 60x=408 and it equals 6.8 but I am assuming you have to round up.

kimi is playing hide-and-seek with Tommy and Manuel. Tommy is hiding 12 feet south of Kimi, and Manuel is hiding due east of Tommy. If Kimi is 20 feet from Manuel, how far apart are Tommy and Manuel?

Answers

Answer:

Tommy and Manuel are 16 ft apart

Step-by-step explanation:

The locations of all three players are shown in the image below

They form a right triangle where the hypotenuse is 20 ft, and one of the legs is 12 ft. We must find the other leg.

We must use Pythagoras's theorem. Being a and b the legs of a right triangle and c its hypotenuse, then

c^2=a^2+b^2

Knowing c and one of the legs, say b:

a^2=c^2-b^2

Using the values c=20, b=12 we find

a^2=20^2-12^2=400-144=256

a=√(256)=16

So, Tommy and Manuel are 16 ft apart

Is a triangle with angle measure 40°,30°,and 120° possible?

Answers

No, a triangle with angles measuring 40°, 30°, and 120° is not possible.

What is a Triangle?

A triangle is a closed shape composed of three angles, three sides, and three vertices. It is one of the most fundamental geometric forms and is represented by the symbol Δ.

A triangle with angle measures of 40°, 30°, and 120° is not possible.

As we know that the sum of the angles in a triangle must always equal 180°.

As per the question, the sum of the angles is 40° + 30° + 120° = 190°, which is greater than 180°.

Therefore, such a triangle cannot exist.

#SPJ2
The total measure of a triangle's angles is always 180 degrees exactly. A triangle with 40, 30, and 120 degree angles has a total of 190 degrees, as 40 + 30 + 120 = 190. Because 190 degrees is greater than 180 degrees, it is not possible.

How do you solve this inequality? 200-15d<80

Answers

1) add 15d to both sides
200<80+15d

2) takeaway 80 from both sides
120<15d

3)divide by 15 to solve the inequality
8<d

Solve 4 1/4 - 2 11/20

Answers

4(1)/(4) - 2(11)/(20)
Change them into improper fractions by multiplying the denominator(bottom) by the whole number then adding the numerator
(17)/(4) - (51)/(20)
You must have a common denominator
Multiply (17)/(4) by (5)/(5)⇒(85)/(20)
(85)/(20)-(51)/(20)=(34)/(20)
Simplify by dividing the numerator by the denominator
34÷20=1(14)/(20)⇒1 (7)/(10) reduced
You answer is 1 (7)/(10)
This could be solved as a group of mixed numbers, but I like to work with improper fractions more.
17/4 - 51/20
Next, you need to find a common denominator.
85/20 -51/20
When adding and subtracting fractions, you only work in the numerator, and the denominator stays the same.
34/20
Then, you just simplify.
Improper fraction: 17/10
Mixed number: 1 7/10
Decimal: 1.7
