Answer:

10/17

Step-by-step explanation:

Each card has two parts. A top part and bottom part. On the top parts of all the cards, there's a simple pattern of adding 2 to the previous number each time. On the bottoms of the cards, you have to add 3 to a number to get to the next number in line. Therefore, take the 4th card (8 on top 14 on bottom) and add a 2 to the top number and a 3 to the bottom number to get the next card in the pattern.

8   +   2   =   10  

---                 ---      

14  +  3   =    17

So card 5 is

10 / 17

Using proportions, it is found that the correct option is given by:

B Ron should replace the pitcher with a relief pitcher.

A proportion is a fraction of a total amount.

In this problem, when Ron replaced the pitcher, the team won 8 out of 14 games, hence the proportion of wins is:

pR = 8/14 = 0.5714.

When Ron kept the pitcher, the team won 4 out of 10 games, hence the proportion of wins is:

pK = 4/10 = 0.4.

Since pR > pK, option B is correct.

Answer:

30

Step-by-step explanation:

You just have to do 150 divided by 5 because you are trying to find out how many pages per day that student read.

The student read 30 pages in one day.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total Pages in a book = 150 pages

Number of days book completed= 5 days

so, each day the student read

= 150/ 5

= 30 pages

Hence, the average rate is 30 pages in one day.

Answer:

The corresponding angles are congruent. The corresponding sides all have the same ratio.

Step-by-step explanation:

Congruent means the angles are equal to each other. There are three pairs of angles. "Matching angles" (not a mathematical term) will be the same/equal/congruent.

The sides would only be same/equal/congruent if the triangles were congruent. For similar triangles, you can find a ratio of sides like big/little or little/big and if you set up the ratios of the matching sides, the ratio will be the same for all three pairs of sides. See image for example.

Divide by 5

Answer:

Step-by-step explanation:

Midpoints of two coordinates is expressed using the formula;

M(X, Y) = (x2+x1/2, y2+y1/2)

Given the coordinates  c(5,3) and d(-3,-6)

x1 = 5, y1 = 3, x2 = -3 and y2 = -6

X = x1+x2/2

X = 5+(-3)/3

X = 5-3/2

X = 2/2

X = 1

Also;

Y = y1+y2/2

Y = 3+(-6)/2

Y = 3-6/2

Y = -3/2

Y = -1.5

The domain of a function is the possible input values, the function can take.

The possible domain is:

The domain of the function is the set of possible values of d.

Because d represents the depth of water,

The starting value can take any value, less than 0

But the end value must be 0 (i.e. the surface of water)

This means that, the domain of the function will be from negative infinity to 0

Hence, the domain is (-infinity, 0}

The time for the job for which the two company are the same is 16

A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,

using linear equation,

y = mx + c

where

Therefore,

y = 345 + 16.25x

Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,

y = 213 + 24.50x

Hence, the time when both cost are the same is as follows;

213 + 24.50x =  345 + 16.25x

213 - 345 = 16.25x - 24.50x

-132 = -8.25x

x = 132 / 8.25

x = 16

He make his Exchange on Friday.

The correct option is B.

A currency's relative value expressed in terms of another currency is called an exchange rate (or group of currencies). The exchange rate is a significant economic variable for nations with active international trade, like Australia.

In other words, the exchange rate is the cost of one currency relative to another.

We have,

Day                 $                 €

monday          1                0.7102
