what is the answer to : classify <1 and <7

Answers

Given:

A figure.

To find:

The classification for angle 1 and angle 7.

Solution:

From the given figure, it is clear that a transversal line intersect two parallel lines and forms 8 angles, 4 angles on each intersection.

In the figure, angle 1 and angle 7 are on opposite sides of the transversal line and outer side of each of those two parallel lines.

Therefore, angle 1 and angle 7 are alternate exterior angles.

Answers

Answer:

s²+r²=t² => r²=s²-t²= 27²-25²

The answer is D

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

'r' and 's' are legs and 't' is the hypotenuse

The Pythagorean Theorem takes the sum of the legs, squared, and sets them equal to the hypotenuse squared.

So in this problem we could start with:

r² + 25² = 27²

r² = 27² - 25²

to get 'r' by itself we take its square root, and what we do to one side of an equation we must also do to the other side, so:

r = [tex]\sqrt{27^2 - 25^2 }[/tex]

Step-by-step explanation:

The diagonals of a rhombus are perpendicular, so ∠AED = 90° and ∠BEC = 90°.

∠DAE = 180° - ∠AED - ∠EDA = 180° - 90° - 35° = 55°

BD is a transversal across parallel sides AD and BC, so ∠EBC = ∠EDA = 35°.

∠BCE = 180° - ∠BEC - ∠EBC = 180° - 90° - 35° = 55°

a car with an initial value of $23,00 is decreasing in value at a rate of 8% each year. Write a function, f(x), that expresses the value of the car in x years

Answers

Step-by-step explanation:

We would apply the formula for exponential decay which is expressed as

A = P(1 - r/n)^ nt

Where

A represents the value after t years.

n represents the period for which the decrease in value is calculated

t represents the number of years.

P represents the value population.

r represents rate of decrease.

From the information given,

P = 23000

r = 8% = 8/100 = 0.08

n = 1

Therefore, the exponential decay function described in this situation is

A = 23000(1 - 0.08/n)1)^ 1 × t

A = 23000(0.92)^t

If A = 15000, then

15000 = 23000(0.92)^t

0.92^t = 15000/23000 = 0.6522

Taking log of both sides to base 10

Log 0.92^t = log 0.6522

tlog 0.92 = log 0.6522

- 0.036t = - 0.1856

t = - 0.1856/- 0.036

t = 5 years to the nearest year

X=1, x= -3, x= -1/2

Step-by-step explanation:

okay, so you've got your zeros right here actually. it's very simple, so I'll give you the reader's digest: SET THEM ALL TO ZERO

x-1=0 add your one, so that's x=1

x+3=0, subtract your 3, so that's x= -3

the last one is tricky: 2x+1=0, 2x= -1, but you can go further. divide your two, and you're left with x= -1/2

The simple interest on an investment of $3600 over 2 years is $504. Find the interest rate to the nearest one decimal place.

Answers

Answer:

7%

Step-by-step explanation:

Given data

Principal=  $3600

Time= 2 years

SImple interest=  $504

The expression for the simple interest is given as

SI= PRT/100

We want to find the rate R

504= 3600*R*2/100

cross multiply'

504*100= 3600*R*2

50400= 7200R

divide both sides by 7200

R= 50400/7200

R= 7%

Hence the rate is at 7%

Of a total of 6,000.00, part was invested at a simple interest rate of 8% and part at 7% if the total interest income for one year was $46.00, how many was invested at 7%

Answers

Answer: Ok so first 0.05(6000 - x) + 0.07x = 372

300 - 0.05x + 0.07x = 372

300 + 0.02x = 372

0.02x = 72

x = 3600

He invested $3600 at 7% and $2400 at 5%.

Hope this helps have a bless day❤️

Step-by-step explanation:

Answer:

Step-by-step explanation:

I think you had a typo where interest should be 460 not 46 because even if the whole 6000 were invested at 7% he would have earned $420 in interest. Also if total investment was switched from 6000 to 600 the 46 in interest would work.

.07x+.08(6000-x)=460

.07x-.08x+480=460

-.01x+480=460

-.01x=-20

x=$2000

which is easy enough to check

2000(.07)+4000(.08)=$460
