Answer:

300

Step-by-step explanation:

sin 14 = 0.99

so, 300/0.99 = x

303.03 = x

rounding off to nearest 100 will give 300.

Please help w/ geometry!

lara [203]

Answer:

<XYZ = 34

Step-by-step explanation:

Remark

Bisected angles means that the original angle (<XYZ in this case) has been cut exactly in half. The two parts that were created from <XYZ are equal so you need only solve for x, solve one of the halves and then double it.

Equation

3x - 7 = 2x + 1

Solution

3x - 7 = 2x + 1 Add 7 to both sides

3x - 7+7 = 2x +1+7 Combine

3x = 2x + 8 Subtract 2x

3x-2x = 2x-2x + 8 Collect like terms on both sides

x = 8

Solution 2

Find one of the bisected parts. You can choose either of the two parts so use 2x + 1

2x + 1

2*8+1

16 + 1

WYZ = 17 degrees

Solution 3

Double <WYZ to get <XYZ

<XYZ = 2 * 17

<XYZ = 34 degrees

PLEASEE HELPPP!!!

Harlamova29_29 [7]

Answer:

The amount is $649.46 and the interest is $49.46.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A=P(1+rn)n⋅t

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

In this example we have

P=$600 , r=8% , n=4 and t=1 years

After plugging the given information we have

AAAA=600(1+0.084)4⋅1=600⋅1.024=600⋅1.082432=649.46

STEP 2: To find interest we use formula A=P+I, since A=649.46 and P = 600 we have:

A649.46II=P+I=600+I=649.46−600=49.46

The equation of line t is y = -2x + 9. Perpendicular to line t is line u, which passes through

Archy [21]

Answer:

Equation of line u in slope-intercept form is: $\mathbf{y=\frac{1}{2}x+9 }$

Step-by-step explanation:

Equation of line t : y = -2x + 9.

We need to find equation of line u, which is perpendicular to line t and passes through point (-10,4)

The equation must be in slope-intercept form.

The general equation of slope-intercept form is: $y=mx+b$ where m is slope and b is y-intercept

Finding Slope:

If two lines are perpendicular, their slopes are opposite i.e $m=-\frac{1}{m}$

Slope of line t: y=-2x+9 we get m =-2 (Comparing with general form y=mx+b, we get m =-2)

Slope of line u: $\frac{1}{2}$

So, we get Slope of line u: m= $\frac{1}{2}$

Finding y-intercept:

Using slope m= $\frac{1}{2}$ and point(-10,4) we can find y-intercept

$y=mx+b\\4=\frac{1}{2}(-10)+b\\4=-5+b\\b=4+5\\b=9$

Equation of line u:

So, equation of line u, having slope m= $\frac{1}{2}$ and y-intercept b=9, we get:

$y=mx+b\\y=\frac{1}{2}x+9$

So, Equation of line u in slope-intercept form is: $\mathbf{y=\frac{1}{2}x+9 }$
