Step-by-step explanation:

The question is incomplete. The complete question is as shown below;

If the answer is not a whole number, it should be entered as a decimal rounded to the hundredths place.

"A photograph with a width of 5.5 inches is being enlarged by a factor of 4 1/2 to make a poster.

The new width of the photograph is_____ inches"

The poster is rectangular in shape. formula for finding the area of a rectangle,

Area A = Length L × width W

Initial width if the photograph = 5.5inches.

If the photograph is enlarged by a factor of 4 1/2, then the new width also increase by that factor since increase in the size of the photograph leads to increase in its area.

New width = 4 1/2 × initial width

New width = 4 1/2 × 5.5

New width = 9/2 × 55/10

New width = 495/20

New width = 24.75inches (to its hundreths place

Find an equation of the line that (a) has y-intercept of -8 and (b) is parallel to the line 6 x − 1 y = 7 6x-1y=7 . Write your a

faust18 [17]

Answer:

The equation of the line in the slope-intercept form is:

$\:y=6x-8$

Step-by-step explanation:

The slope-intercept form of the equation of a line is

$y\:=\:mx\:+\:b$

As y intercept is -8, we have

$y\:=\:mx\:-8$

Since the line is parallel to $6x-y=7$ , then it has the same slope.

Let's put this equation in $y\:=\:mx\:+\:b$ form and find the slope

$6x-y=7$

$y=6x-7$

Thus, the slope is :

$m = 6$

Now we can finish the equation of the line in the slope-intercept form

$y\:=\:mx\:+\:b$

$\:y=6x-8$ ∵ $m = 6$ , b = -8

Therefore, the equation of the line in the slope-intercept form is:

$\:y=6x-8$

For triangle xyz , the measures of angles x,y, and Z are known. Which method should be used to start solving triangle xyz?

Kisachek [45]

Neither the <u>laws of sines</u> nor the <u>law of cosines</u> can be used to solve the triangle. The correct option is the third option - neither law can be used

<h3>Solving trianngles using the laws of sines & cosines </h3>

The law of sines is written as

$\frac{sinA}{a}=\frac{sinB}{b}= \frac{sinC}{c}$

Where a,b, and c are sides of any given triangle and A,B, and C are the angles.

This law is used when we are given either

Two angles and one side, or
Two sides and a non-included angle

The law of cosines is written as

a² = b² + c² -2bc cosA, or

b² = a² + c² - 2ac cosB, or

c² = a² + b² -2ab cosC

Where a,b, and c are sides of any given triangle and A,B, and C are the angles.

This law is used when we are given either

Three sides or
Two sides and the included angle

Now, for triangle xyz, which the measures of angles X,Y, and Z are known, neither law can be used to solve the triangle.

Hence, neither the <u>laws of sines</u> nor the <u>law of cosines</u> can be used to solve the triangle. The correct option is the third option - neither law can be used

Bus A and Bus B leave the bus depot at 5 pm. Bus A takes 30 minutes to complete its route once and bus B takes 35 minutes to com

shepuryov [24]

Answer:

Step-by-step explanation:

Bus A will take 1 hour and will arrive back at 6pm, because 30+30=60 and there are 60 min is one hour. Bus B will arrive 1 hour 10 minuets. 35+35=70, Knowing that it will arrive there in over an our because there is more than 60 min, and the extra ten is the amount of minuets. SO bus B will arrive at 6:10pm. Hope I explained this right.
