0.25q + 0.10d = 1.25
q + d = 8....q = 8 - d

0.25(8 - d) + 0.10d = 1.25
2 - 0.25d + 0.10d = 1.25
-0.25d + 0.10d = 1.25 - 2
-0.15d = - 0.75
d = -0.75/-0.15
d = 5 <=== there are 5 dimes

q + d = 8
q + 5 = 8
q = 8 - 5
q = 3 <=== there are 3 quarters

<u>Corrected Question</u>

The Venn diagram shows three types of numbers: odd (O), even (E), and prime (P). Which is represented by Ø?

(A)  O ⋃ P  (B)E ∩ P   (C)O ⋃ E   (D)E ∩ O

Answer:

(D) E ∩ O

Step-by-step explanation:

The Venn diagram is reproduced and attached below.

In the Venn diagram, the sets of Odd(O) and Even(E) numbers are disjoint, i.e. there is no intersection.

We can also say the intersection of sets O and E is the empty set.

Therefore: E ∩ O is represented by the empty set Ø.

Generally speaking, a number cannot be even and odd at the same time.

The correct option is D

I need help with these question! Please do step by step-
trapecia [35]

Answer:

There are 47 Borogroves and 35 Mome raths

Step-by-step explanation:

Here, given the number of legs, we want to find the number of each type of animals

Let the number of borogoves be b and the number of mome raths be m

From the question, there are 82 creatures;

Thus;

m + b = 82 ••••••••(i)

the total number of legs by b borogroves will be b * 2 = 2b

the total number of legs by m mome raths will be m * 4 = 4m

the sum of all legs is 234

2b + 4m = 234 •••••••••(ii)

From equation 1, m = 82-b

Substitute this into equation ii

2b + 4(82-b) = 234

2b + 328 - 4b = 234

4b-2b = 328-234

2b = 94

b = 94/2

b = 47

Recall;

m + b = 82

m + 47 = 82

m = 82-47

m = 35
