Find the missing measurements in triangle ABC. Round your answer to the nearest tenth if necessary.
Measure of Angle B=
AB=
AC=
Answers
Answer:
m∡B = 55°
AB = 5.2
AC = 7.4
Step-by-step explanation:
m∡B = 180-(90+35)
use Law of Sines to find AB and AC:
sin 90° / 9 = sin 35°/AB
AB = .57(9) = 5.2
sin 90° / 9 = sin 55°/AC
AC = .82(9) = 7.4
The solution is,
m∡B = 55°
AB = 5.2
AC = 7.4
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
here, we have,
from the given figure, we get,
m∡B = 180-(90+35)
=55
use Law of Sines to find AB and AC:
sin 90° / 9
= sin 35°/AB
AB = .57(9)
= 5.2
sin 90° / 9 = sin 55°/AC
AC = .82(9
= 7.4.

 A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and a height of 60 centimeters. If the company used 54,259.2 cm3 of steel, how many rods did it make? Use 3.14 do not round your answer +Help me plz
Answers
Answer:
72 rods
Step-by-step explanation:
First, find the volume of each rod, using the formula V = [tex]\pi[/tex]r²h
Plug in pi, the radius, and height, and solve:
V = [tex]\pi[/tex]r²h
V = (3.14)(2²)(60)
V = (3.14)(4)(60)
V = 753.6
So, each rod has 753.6 cm³ of steel.
Divide 54,259.2 by this to find how many rods it will make:
54,259.2 / 753.6
= 72
So, it will make 72 rods.

Given that x = 9.5 m and θ = 20°, work out AC rounded to 3 SF
Answers
Answer:
AC ≈ 10.1 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos20° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{9.5}{AC}[/tex] ( multiply both sides by 9.5 )
AC × cos20° = 9.5 ( divide both sides by cos20° )
AC = [tex]\frac{9.5}{cos20}[/tex] ≈ 10.1 m ( to 3 sf )

Megan is the manager of a computer shop she organises a sale with 18% off all tables Megan changes the price of own table from £389 to £330.98 has Megan changed the price probably
Answers
Answer:
this is easy. all you have to do is figure out what 18% of 389 is and then subtract that answer from 389. the easy trick i use is to make a fraction with the numerator being a question mark and the denominator being 389 (displayed below). then you would make a second fraction with 18 as the numerator and 100 being the denominator (displayed below). you would then multiply 389 with 18 and divide by 100 to get the numerator of the first fraction (which is 70.02). now you subtract 70.02 from 389 (being 318.98). this would mean that Megan has not done the math correctly.
Step-by-step explanation:
?/389 = 18/100
389 x 18 = 7002
100/7002 = 70.02
389 - 70.02 = 318.98

Alison runs a mile in 5 minutes and 50 seconds. Elizabeth runs a mile in 6 minutes and 40 seconds. What is the ratio of Alison's time to Elizabeth's time?
a) 7:8
b) 5.5:6.4
c) 55:64
d) 8:7
Answers
Answer:
7:8
Step-by-step explanation:
First, convert their times to common units. You'll want to put it in seconds:
5 minutes and 50 seconds = 350 seconds
- multiply 5 minutes by 60 to get it into seconds and then add the other 50 seconds to it
- for Elizabeth's time, multiply 6 by 60 seconds and add 40 to it
To get the ratio of their times, divide Alison's time by Elizabeth's time:
350 ÷ 400 = 7:8
Answer:
a) 7:8
Step-by-step explanation:
Alison: 5 minutes and 50 seconds = 355 seconds
Elizabeth: 6 minutes and 40 seconds = 400 seconds
355:400, reduces to 71:80 or 7:8

In science class, Farah uses a graduated cylinder with
water in it to measure the volume of some marbles. She
drops in marbles so that they're all under water and
measures the height of the water.
After dropping in 4 marbles, the height is 10 ml
After dropping in 6 marbles, the height is 11 ml.
Here are your answers from the previous screen:
Before dropping in any marbles, the height is 8 ml.
Each marble increases the height by 3 mL.
What should be the height of the water after 13 marbles
are dropped in?
Answers
Answer:
47 mL
Step-by-step explanation:
Note each marble increases the height by 3 mL, and we start with 8 mL, so we multiply 3 by 13, and add it to 8
The volume of each marble is 0.5 ml. The volume after dropping 13 marbles is 14.5 ml.
VolumeThe volume of an object is the amount of space occupied by a three dimensional object.
A graduated cylinder can be used to measure the volume of a cylinder. Given that After dropping in 4 marbles, the height is 10 ml and After dropping in 6 marbles, the height is 11 ml.
Hence:
Volume per marble = (11 ml - 10 ml) / (6 - 4) = 0.5 ml
The volume of each marble is 0.5 ml.
If the initial volume is 8 ml, after 13 marbles, height = (8 ml + 0.5 * 13) = 14.5 ml.

Seven friends share 3 bags of trail mix equally. What fraction of a bag of trail mix does each friend get? Each friend will receive of a bag of trail mix.
Answers
Answer:
Step-by-step explanation:
There are 3 bags to be shared among 7 people.
Therefore each person will get 3/7 bags.
I couldn't think of a way of explaining the question in terms of bags when I wrote my answer. Suppose you try this.
Weigh each bag separately.
Add the weights (or masses) together.
Divide by 7
Another way is to weigh each bag separately. There are three bags and seven people. Each person will get 3 parts of the total divided by 7.
This will solve the problem in a practical manner. Give the Brainliest to the other responder who did a much better job of explaining it than I have.
Answer:
[tex]\frac{7}{3}[/tex] or 2[tex]\frac{1}{3}[/tex] of a bag of trail mix
Step-by-step explanation:
To find the fraction of trail mix each friend will get, divide the number of friends by the number of bags of trail mix:
Since there are 7 friends and 3 bags of trail mix, the fraction will be [tex]\frac{7}{3}[/tex]
This can also be simplified to a mixed fraction, 2[tex]\frac{1}{3}[/tex]
So, each friend will receive [tex]\frac{7}{3}[/tex] or 2[tex]\frac{1}{3}[/tex] of a bag of trail mix.
Rectangle A has area 50 cm 2 and length 10 cm. The area of rectangle B is one-half the
area of rectangle A. The rectangles have the same length.
What is the width of rectangle B?
Answers
Answer:
2.5
Step-by-step explanation:
Area of A is 50 cm ^2
length of A is 10
Area of B is 50/2 cm^2 or 25cm^2
area for all rectangles is length * width
so area of B divided by length of b is width of b
25/10 = 2.5
width of b is 2.5

Which rule describes the composition of transformations that maps triangle BCD to triangle B""C""D""?
Answers
Answer:
(d)
Step-by-step explanation:
Given
See attachment for [tex]\triangle BCD[/tex] and [tex]\triangle B"C"D"[/tex]
Required
The transformations
Using B and B"" as points of reference, we have:
[tex]B = (1,4)[/tex]
[tex]B"" = (5,-1)[/tex]
The transformation is as follows:
First, reflect across y axis.
The rule is:
[tex](x,y) \to (-x,y)[/tex]
So, we have:
[tex]B(1,4) \to B'(-1,4)[/tex]
Next, translate 6 units right.
The rule is:
[tex](x,y) \to (x + 6,y)[/tex]
So, we have:
[tex]B' (-1,4) \to B"(-1 + 6,4)[/tex]
[tex]B' (-1,4) \to B"(5,4)[/tex]
Lastly, translate 5 units down
The rule is:
[tex](x,y) \to (x,y-5)[/tex]
So, we have:
[tex]B"(5,4) \to (5,4-5)[/tex]
[tex]B"(5,4) \to (5,-1)[/tex]
Hence; (d) is correct
