Zaira spent 55 hours in 2 weeks working on a science project. she worked 32 hours the first week. Write and solve an addition equation to find the amount of time she spent working the second week.

Answers

Answer 1
If x is work in the 2nd week, 32 + x = 55. Subtract 32 from both sides to get x = 23.

Line segment XY is tangent to circle Z at point U. If the measure of UV is 84, what is the measure of YUV. A. 42 B. 84 C. 96 D. 168

Answers

Answer:

The measure of angle YUV is equal to [tex]m<YUV=42\°[/tex]

Step-by-step explanation:

see the attached figure to better understand the problem

we have that

[tex]arc\ UV=84\°[/tex] -----> given problem

so

[tex]m<UZV=84\°[/tex] ------> by central angle

we know that

The triangle UZV is an isosceles triangle

because

[tex]ZU=ZV=radius[/tex]

so

[tex]m<ZUV=m<ZVU[/tex] -----> bases angle of the isosceles triangle

Remember that

The sum of the internal angles of a triangle is equal to [tex]180\°[/tex]

so

[tex]m<ZUV+m<ZVU+m<UZV=180\°[/tex]

[tex]2m<ZUV+m<UZV=180\°[/tex]

substitute and solve for m<ZUV

[tex]2m<ZUV+84\°=180\°[/tex]

[tex]m<ZUV=(180\°-84\°)/2=48\°[/tex]

[tex]m<ZUV+m<YUV=90\°[/tex] ------> by complementary angles

solve for m<YUZ

[tex]48\°+m<YUV=90\°[/tex]

[tex]m<YUV=90\°-48\°=42\°[/tex]

How much will it cost to mail a first-class letter that weighs 2.8 oz?
The rate is $.22 for the first ounce and $.17 for each additional
ounce or fraction of an ounce.
a. $.56
b. $5.60
c. $.53
d. $.39

Answers

Final answer:

The total cost to mail a first-class letter that weighs 2.8 oz is $0.56, which includes $0.22 for the first ounce and $0.34 for the additional weight.

Explanation:

To calculate the cost of mailing a first-class letter that weighs 2.8 oz, you need to know the initial rate for the first ounce and the rate for each additional ounce. According to the given rates, the cost for the first ounce is $0.22, and each additional ounce (or fraction thereof) costs $0.17.

Since the letter weighs 2.8 oz, you have 1.8 oz over the first ounce. Thus, you need to pay for 2 additional ounces.

The total cost = cost for first ounce + cost for additional ounces = $0.22 + 2 x $0.17 = $0.22 + $0.34 = $0.56. Therefore, the correct answer is (a) $.56.

Answers

Ken will make d. $1,026.60 in profit on his shares.
 

Answer:

$1026.60

Step-by-step explanation:

Today's stock listing for Bukkia hog farms as shown below :

Frank is constructing the circumscribed circle for △XYZ. He has already used his compass and straightedge to complete the part of the construction shown in the figure.



Which construction could be his next step?


Place the point of the compass on point Y and draw an arc intersecting the two arcs.

Place the point of the compass on point X and draw an arc intersecting the two arcs.

Place the point of the compass on point Z and draw an arc through points X and Y.

Place the point of the compass on one of the arcs and draw an arc through point X.

Answers

circumscribed circle for a triangle is circle where the circumference would cut all the vertices in the triangle 
the diagram already has arcs marked from point Y, with the aim of drawing a perpendicular bisector to line XY.

Therefore the next step is to place the compass on point X and draw two arcs which cross the arcs already drawn (second option is the correct answer)

The points at which the 2 arcs meet are connected to each other making a perpendicular bisector that would cut XY perpendicularly.

Next step is to place the compass at Z and draw 2 arcs between Z and Y points, similarly place the compass at Y and draw 2 arcs that would cut the arcs already drawn. 

Then connect the two points where the arcs meet and thats the perpendicular bisector of ZY.
The point at which perpendicular bisectors of XY and YZ meet is known as the circumcenter. Place the compass on this point with the radius any of the three points X,Y or Z and draw the circle

Answer:

Place the point of the compass on point X and draw an arc intersecting the two arcs.

Step-by step explanation:

This is to complete the angle bisector.

A bamboo shoot is 20 inches tall at day 0 and grows 24 inches each day. which function(s) shown below can be used to determine height, f(n), of the bamboo after n days?
I. f(n)=24n+20
II. f(n)=24n+20(n-1)
III. f(n)=f(n-1)+24 where f(0)=20

Answers

The only correct answer is I. f(n)=24n+20

Answer:

The correct answer is option I

Step-by-step explanation:

Initial height of bamboo [tex]= 20 in\\[/tex]

Height of bamboo grows by [tex]24 in \\[/tex] every day

Let "n" be the number of days

So the height of bamboo after "n" days is

[tex]f(n) = 20 + 24n\\[/tex]

Thus, the correct answer is option I

What is Scale?

The ratio between a distance on a map and its actual distance on the ground is known as the map's scale. Since scale must vary throughout a map due to the curvature of the Earth's surface, this straightforward idea is made more difficult. This change makes the idea of size significant in two different ways.

Given, An advertisement on a billboard measures 22 ft long and 8 ft high. If the ad is transferred to the side of a bus and is 30 ft. Long.

when the advertisement is 22 ft long then the height is 8 ft.

So,

When the advertisement is 1 ft long then the height is =  8/22 ft.

the advertisement is 1 ft long then the height is =  4/11 ft.

thus,

the advertisement is 30 ft long then the height is =  4/11 * 30 ft.

the advertisement is 30 ft long then the height is =  120/11 ft.

the advertisement is 30 ft long then the height is =  10 ft 11 inches.

Therefore, When the advertisement is 30 ft long then the height is 10 ft 11 inches.

In GHI, HI = IHG =3x + 4, and IGH = 2x - 24. What is HIG?

Answers

HIG=16×44=704 its correct okke mmm
HI = GH so GHI is an isosceles triangle

<IGH = <HIG = 2x - 24

as you know sum of interior angles in a triangle = 180
so
2(2x - 24) + 3x + 4 = 180
4x - 48 + 3x + 4 = 180
7x - 44 = 180
7x = 224
  x = 32

so
<HIG = <IGH = 2(32) - 24 = 64 - 24 = 40

answer
