Which statement is true about ∠JXM and ∠NXP? a.∠JXM and ∠NXP are complementary. b.∠JXM and ∠NXP are vertical. c.∠JXM and ∠NXP ar
xenn [34]

Answer:

Incomplete questions

Check attachment for correct question.

The correct answer is

A. ∠JXM and ∠NXP are complementary

step explanation:

line JP is a straight line and sum of angle on a straight line is 180°.

There are three angles on this straight line JP which are ∠JXM, ∠NXP and ∠MXN

Note: from the attachment, it is shown that ∠MXN is a right angle i.e. 90°.

Then, sum of angle on this line is 180°.

∠JXM + ∠NXP + ∠MXN = 180°

∠JXM + ∠NXP + 90° = 180°

∠JXM + ∠NXP = 180° — 90°

∠JXM + ∠NXP = 90°

From the definition of complementary angles : Two Angles are said to Complementary if their sum is 90° (a Right Angle).

They don't have to be next to each other, just so long as the sum is 90 degrees.

Then, since ∠JXM + ∠NXP add up to 90°, it shows that ∠JXM and ∠NXP are complementary

So the correct option is A

My question is: 40 people voted for ""other"". what’s the estimate of total voters from part (b) accurate?
kirill [66]

Answer:

No

Step-by-step explanation:

From part (b)

If number who voted = 280

Number of voters who would have voted Geron:

35% * 280

0. 35 * 280 = 98 voters

40 people voted for others:

To check if estimate from. Part b is accurate :

10% voted for others

10% of estimated voters = 40

Let, number of estimated voters = x

0.1 * x = 40

0.1x = 40

x = 40/0.1

x = 400

If 40 people Voted others, the the number of voters should be 400 and not 280

what interest rate is needed to turn $2500 into $15,000 in 14 years if interest is compounded weekly?
Anastasy [175]

Answer:

0.6845% per week.

Step-by-step explanation:

Simple Interest Calculation A = P(1 + rt)

Solving our equation:

r = (1/730.5)((15000/2500) - 1) = 0.00684463

r = 0.00684463

Converting r decimal to R a percentage

R = 0.00684463 * 100 = 0.6845%/week

Calculating the annual rate

0.6845%/week × 52 weeks/year = 35.594%/year.

The interest rate required to get a total amount, principal plus interest, of $15,000.00 from simple interest on a principal of $2,500.00 over 14.05 years (730.5 weeks) is 0.6845% per week.

How many three-digit positive integers <img src="https://tex.z-dn.net/?f=x" id="TexFormula1" title="x" alt="x" align="absmiddle"
Anastaziya [24]

Answer:

  40

Step-by-step explanation:

Any solution x will mod 23 will also have x+23n as a solution, for some integer n. Since 900/23 = 39 3/23, we know there are 39 or 40 three-digit integers of this form.

As it happens, 100 is the smallest 3-digit solution. So, there are 40 three-digit numbers that are of the form 100 +23n, hence 40 solutions to the equation.

_____

The equation reduces, mod 23, to ...

  10x = 11

Its solutions are x = 23n +8.

Three numbers a;b; 9; ... are in geometric sequence. If 1 is subtracted from the first term then
kenny6666 [7]

if a b 9 are in GP

b÷a = 9 ÷ b

b^2 = 9a

if a - 1 b 9 are in AP

2b = a+8

b = a+8÷2

substitute

b is equal to a + 8 by 2 in b square equal to 9 a

(a+8÷2)^2 = 9a

a^2+16a+64 = 36a

a^2 -20a +64 =0

(a-16) (a-4) =0

a= 16 or a=4

when a=16 b= 12

when a=4 b= 6

Value of a and b are given above
