A photograph measures 5 inches wide and 7 inches long. If you have the photograph enlarged to fit a frame 49 inches long, what is the widest the photograph can be?

Answers

1,715 inch’s please let me know if I’m wrong
The photograph can be no wider than 35 inches I believe. If the original was 7 inches and now 49 then it was multiplied by 7 so I’m assuming that’s what you would do to the width as well which would give you 35.

Answers

Answer:

d) (5,4)

Step-by-step explanation:

Answer:

D. (5, 4)

Step-by-step explanation:

First, we need to know how coordinate [order] pair works.

(x, y)

That means, (5, 4) is 5 unit on the x-axis and 4 unit on the y-axis.

East means to the right on the graph (+) ;

South means going downward on the graph (-) ;

West means to the left on the graph (-) ;

North means going upward on the graph (+) .

So first, (5, 4) 5 units east meaning that we are moving the x-axis and moving right. 5 [in the order pair] + 5 [unit east] = 10

After the first step, we have (10, 4)

Moving (10, 4) 4 units south meaning that we are moving the y-axis and moving downward on the graph. 4 [in order pair] - 4 [unit south] = 0

After the second step, we have (10, 0)

Moving (10, 0) 4 units west meaning that we are moving the x-axis again and moving left this time. 10 [in order pair] - 4 [unit west] = 6

After the third step, we have (6, 0)

Moving (6, 0) 4 units north meaning that we are moving the y-axis again and moving upward on the graph. 0 [in order pair] + 4 [unit north] = 4

After the forth step, we have (6, 4)

Moving (6, 4) 1 unit west meaning that we are moving the x-axis again and moving left. 6 [in order pair] - 1 [unit west] = 5

After the final step, we have (5, 4)

Therefore, the answer to this question is D. (5, 4)

Though there is an easier version of this, which require some brain to do, but here's how-

Same above, we need to know that east and west moves sideways (east use +, west use -)

And north and south moves up and down (north use +, south use -)

And then we need to sort out how many steps moves sideways and how many steps moves up & down.

5 units east, 4 units west, and 1 unit west. And we put this in an equation for the x-axis. 5 [original] +5 [units east] -4[units west] -1[units west] = 5

Which would still get us 5 for the x-axis.

4 units south and 4 units north balanced out, which still is 4 for the y-axis.

Put the order pair together: (5, 4)

And we got the same answer: D. (5, 4)

I hope this helps!

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Player A is the most consistent, with a range of 5.

Answers

Answer: Player B is the most consistent, with an IQR of 3.5.

Step-by-step explanation:

For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).

For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).

Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

An equation is a mathematical statement that shows two mathematical expressions equal.

An equation consists a variable that does not have a fixed value to it.


Given,

j+12=25

Here ‘j’ is the variable.

To find ‘j’ we just need to 12 from 25.

So, 25 - 12 = 13

Hence, now we know that ‘j’ is equal to 13.

Answer:

Step-by-step explanation:

248.85

Answer:

221.47m^2

Step-by-step explanation:

To estimate the area of a circle, we can use the formula:

Area = π x (radius)^2

Since the diameter of the circle is given as 16.8m, we can first find the radius by dividing the diameter by 2:

radius = diameter / 2 = 16.8m / 2 = 8.4m

Now, using the given value of pi as 3.14, we can estimate the area of the circle as:

Area = π x (radius)^2

= 3.14 x (8.4m)^2

= 3.14 x 70.56m^2

= 221.47m^2 (rounded to the nearest hundredth)

Therefore, the estimated area of the circle is approximately 221.47 square meters.

Angle next to 110= 180 - 110 = 70 degrees.
Sum of interior angles of a triangle = 180 degrees.
So, 180 - (40 + 70) = 180 - 110

So, angle next to 70= 180 - 70 = 110 degrees.

800 students attend Ridgewood Junior High School. 25% of students bring their lunch to school everyday.

Answers

To find the number of students who brought their lunch to school on Thursday, we can start by calculating 25% of the total number of students.

25% of 800 students is (25/100) * 800 = 200 students.

Therefore, 200 students brought their lunch to school on Thursday.
according to my understanding it’s 200

800*200= 2000
