a rectangular field measures 10 yards by 24 yards. What is the distance, d, from one corner to the opposite corner?

1 answer:

5 0

Using the Pythagorean theorem to solve this, d=26, here's how.
a^2+b^2=c^2
plug in the numbers you already have
10^2+24^2=d^2
100+578=676
676=d^2
take the square root of that
√676=26
d=26

Hey!

------------------------------------------------

Surface Area Formula: 2LW * 2LH * 2WH

------------------------------------------------

2LW:

5 x 1 = 5

5 x 2 = 10

------------------------------------------------

2LH:

4 x 1 = 4

4 x 2 = 8

------------------------------------------------

2WH:

5 x 4 = 20

20 x 2 = 40

------------------------------------------------

Surface Area:

40 + 8 + 10= 58

Xerxes, Murray, Norah, Stav, Zeke, Cam, and Georgia are invited to a dinner party. They arrive in a random order and all arrive

Nikolay [14]

Answer:

0.143

Step-by-step explanation:

From counting principle, we can say that:

There are 7! ways of the 7 people to arrive first. Any one of them can come first. But, what is the probability that Xerxes with arrive first?

We take that Xerxes is the first one to arrive, then from the 7 - 1 = 6 remaining people, they can arrive in 6! ways. So

Probability Xerxes arrives first = 6!/7! = 0.1429

Rounding to 3 decimal places, it will be:

<u>Probability Xerxes arrives first = 0.143</u>

Jamie runs a math-tutoring program. For each student, she charges an enrollment fee of $63.00 plus $18.00 per hour of tutoring.

Tamiku [17]

Answer:

The best and most correct answer among the choices provided by your question is the third choice or letter C. The total number of hours is 17.

For h>7

C=210+20(h-7)

C=210+20h-140

C=20h+70, h>7

410=20h+70

20h=340

h=17 hours

What is (4x + 3) + (-2x + 4)

kobusy [5.1K]

Answer:

(4x + 3) + (-2x + 4) = 2x + 7

Step-by-step explanation:

(4x + 3) + (-2x + 4) = you then collect like terms

(4x + -2x) + (3 + 4)= like this, and you add what's inside perenthesis

= 2x + (3 + 4). step-by-step

= 2x + 7. then that is how you get =2x+7

The graph of the equation y = 3x − 4 is shown. What statement is true about every point on the graph? Math item stem image CLEAR

8090 [49]

Answer:

C. If you triple the x-coordinate and then subtract 4, you get the y-coordinate.

Step-by-step explanation:

We are given the graph of the equation y = 3x -4 as shown below.

Substituting x =3 in the equation gives us,

y = 3x - 4

i.e. y = 3 × 3 - 4

i.e. y = 9 - 4

i.e. y = 5

Thus, we get the point ( x,y ) = ( 3,5 ).

Here, x = 3 < 5 = y.

So, option A is not correct.

Also for ( 3,5 ), we have y = 5 = 3 + 2 = x + 2 i.e. y is not 3 less than x.

This shows that option B is also not correct.

If we put x = 0 in the equation, we get y = 3x -4 i.e y = -4.

Thus, both x and y co-ordinate do not have the same sign.

So, option D is wrong.

Hence, option C is correct i.e. we get the y-coordinate, when we triple the x-coordinate and then subtract 4.
