What is the value of d to the nearest tenth?

irina1246 [14]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

PA = 22

PB = 22+40=62

PC = 26

PD = 26+d

As we know the rule of tangents :

PA.PB=PC.PD

$22\times 62=26(26+d)\\\\1364=676+26d\\\\1364-676=26d\\\\688=26d\\\\\dfrac{688}{26}=d\\\\d=26.46\\\\d=26.5$

Hence, First option is correct.

Find the distance to the nearest tenth,between S(6,5) and T(-3,-4)

Doss [256]

Answer:

<h3>The answer is 12.7 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

S(6,5) and T(-3,-4)

The distance between them is

$|ST| = \sqrt{ ({6 + 3})^{2} + ({5 + 4})^{2} } \\ = \sqrt{ {9}^{2} + {9}^{2} } \\ = \sqrt{81 + 81} \\ = \sqrt{162} \\ = 9 \sqrt{2} \: \: \\ = 12.7279...$

We have the final answer as

<h3>12.7 units to the nearest tenth</h3>

Hope this helps you

"A cash drawer contains 29 bills, all twenties and fifties. If the total value of the bills is $820, how many twenties and how m

maks197457 [2]

Answer:

There are 21 twenties and 8 fifties in the drawer.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of twenties

y is the number of fifties.

A cash drawer contains 29 bills.

This means that x + y = 29.

The total value of the bills is $820.

This means that 20x + 50y = 820.

x + y = 29

20x + 50y = 820

From the first equation, x = 29 - y. So:

20x + 50y = 820

20(29 - y) + 50y = 820

580 - 20y + 50y = 820

30y = 240

y = 8

And

x = 29 - y = 29 - 8 = 21

There are 21 twenties and 8 fifties.

Can someone Help?!? I dont get the Key

Shtirlitz [24]

The answer is C, four
because the answer before the line is the ten so the 7 is a 70
the number after the line is a unit, so a 6 is a 6
so the number would be 76
all the numbers before 70 you just have to count
and there is 4, so its C
