4vir4ik [10]3 years ago

5 0

Answer:less than

Step-by-step explanation:

1/5 x 2 1/5 = 11/25

2 1/5 as a mixed number is 11/5

so 11/25 is less than 11/5 therefore

1/5 x 2 1/5 < 2 1/5

17. Solve the following:<br> x – 3y = 5<br> 5x – 2y = -1

Phantasy [73]

Answer:

(- 1, - 2 )

Step-by-step explanation:

Given the 2 equations

x - 3y = 5 → (1)

5x - 2y = - 1 → (2)

Rearrange (1) expressing x in terms of y by adding 3y to both sides

x = 5 + 3y → (3)

Substitute x = 5 + 3y in (2)

5(5 + 3y) - 2y = - 1 ← distribute left side

25 + 15y - 2y = - 1

25 + 13y = - 1 ( subtract 25 from both sides )

13y = - 26 ( divide both sides by 13 )

y = - 2

Substitute y = - 2 in (3) for corresponding value of x

x = 5 + (3 × - 2) = 5 - 6 = - 1

Solution is (- 1, - 2 )

An electric company has to track on-time payments and late payments for each customer monthly. It is impossible for a customer t

OLga [1]

Answer:

The probability that a customer pays late each month is P(B) = 0.27

Step-by-step explanation:

Let P( A ) be the probability that the customer pays on time and the value is 0.55

Let P( B ) be the probability that a customer pays late each month

The probability that a customer pays late or on-time each month is P(A u B) and the value is 0.82

The probability that a customer pays on-time and late each month is P(A n B) and the value is zero ( 0 ) given that it is impossible

Now The probability that a customer pays late or on-time each month is mathematically represented as

P(A u B) = P(A) + P(B) - P(A n B)

=> 0.82 = 0.55 + P( B ) - 0

=> P(B) = 0.27

The following triangles are similar. Find x.

AlladinOne [14]

Let's use the line on the right side. In the smaller triangle, the length is 4. The same side on the bigger triangle is 12. The ratio of the smaller triangle to the bigger triangle is:

$\frac{4}{12} \rightarrow 4:12$

$12 \div 4 = 3$

To find a side length for the bigger triangle, all you need to do is multiply by 3. The same side on the smaller triangle is 5. Multiply by 3

$5 \times 3 = 15$

That means x = 15

If ΔGET≅ΔMAP, then what corresponding parts are congruent? segment TG and segment AM ∠T and ∠P segment MP and segment ET ∠E and

otez555 [7]

Answer:

2nd Option is correct that is ∠T and ∠P.

Step-by-step explanation:

We are given that ΔGET ≅ ΔMAP

We need to find Congruent part from the given options.

Since, we are given the figure of the congruent triangles with marking not any instruction with which vertex is congruent to which vertex.

So, The Given Name of the Congruent triangle.

We deduce that

G ↔ M

E ↔ A

T ↔ P

Using this we get following congruent parts,

GE ≅ MA , GT ≅ MP and ET ≅ AP

∠G ≅ ∠M , ∠E ≅ ∠A and ∠T ≅ ∠P.

Therefore, 2nd Option is correct that is ∠T and ∠P.

The largest telescope in the world is powerful enough to identify a penny that is 5 miles away. How many yards is this?

mojhsa [17]

We are given

The largest telescope in the world is powerful enough to identify a penny that is 5 miles away

it means that

distance =5 miles

we can change it into yards

we know that

1 mile=1760 yards

$d=5\times 1mile$

we can replace 1 mile

$d=5\times 1760 yards$

$d=8800 yards$

So, distance in yards is 8800 yards..........Answer
