Find the length of side BC.
Give your answer to 3 significant figures.
С
A
71°
6.3 cm
B
Answer:
19.3 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle B = 71°
Adjacent = 6.3 cm
Hypothenus = BC =?
The length BC can be obtained by using cosine ratio. This is illustrated below:
Cos B = Adjacent / Hypothenus
Cos 71 = 6.3 / BC
0.3256 = 6.3 / BC
Cross multiply
0.3256 × BC = 6.3
Divide both side by 0.3256
BC = 6.3 / 0.3256
BC = 19.3 cm
Thus, Lenght of side BC is 19.3 cm

12 < 8 + x
A. X> 4
B. x < 20
C. x<4
D. x>20
Answer:
[tex]12 < 8 + x \\ 12 - 8 < x \\ 4 < x \\ \boxed{ x > 4}✓[/tex]
A. x>4 is the right answer.At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual.
Answer
The tool set costs $68 during the sale this week.
Explanation
We know that...
Normally the tool set costs $80.
During the sale, the tool set costs $12 less than usual.
So you should subtract to find the cost of the tool set during the sale.
80-12=68
So the tool set would cost $68 during the sale.
The volume of a cube is 216 ft. What is the length of a side?
Answer: 6 in.
Step-by-step explanation:
Hope this helped! :)
Answer:
6 ft
Step-by-step explanation:
The cube root of 216 is 6. So 6x6x6 = 216. A cube has all equal sides resulting in the length, 6 ft.
Nikki has $1100 and spends $35 per week. Mich has $520 and saves $55 per week. In about how many weeks, will Nikki and Micah have the
same amount of money?
(round to the nearest whole number)
Answer:
6 weeks
Step-by-step explanation:
Given that :
Nikki :
Initial amount = $1100 ;
Amount spent per week = $35
Mich:
Initial amount = $520
Amount saved per week = $55
Number of weeks they'll both have the same amount :
Let number of weeks = w
For Nikki who is spending :
1100 - 35w - - - (1)
For Mich who is saving :
520 + 55w - - - (2)
Equate (1) and (2)
1100 - 35w = 520 + 55w
1100 - 520 = 55w + 35w
580 = 90w
w = 580 / 90
w = 6.444

Step-by-step explanation:
Total pieces of art = 120
He puts 5% of them in an art show
How many pieces of art dose Jason put in the art show ?
pieces of art dose Jason put in the art show = 5% of 120
= 5/100 × 120
= 0.05 × 120
= 6
Therefore, Jason put 6 pieces of art dose in the art show

Given:
The triangle PQR on a coordinate plane.
To find:
The image of point Q after a rotation of 90° counterclockwise about the origin.
Solution:
From the given graph, it is clear that the coordinates of point Q are (5,0).
If the figure is rotated 90° counterclockwise about the origin, then the rule of rotation is defined as
[tex](x,y)\to (-y,x)[/tex]
Using this rule, we get
[tex]Q(5,0)\to Q'(-(0),5)[/tex]
[tex]Q(5,0)\to Q'(0,5)[/tex]
So, the image of point Q is (0,5).
Therefore, the correct option is (a).

question is attached
Answer:
Please check explanations
Step-by-step explanation:
Mathematically;
csc 2 theta = 1 / sin 2 theta
Sin 2 theta = sin (theta + theta)
= 2sin theta cos theta
So therefore;
csc 2 theta = 1/2(sin theta cos theta)
= 1/2 * 1/sin theta * 1/ cos theta
1/sin theta = csc theta
1/cos theta = sec theta
Thus;
csc 2 theta = 1/2 * csc theta * sec theta
csc 2 theta = 1/2 sec theta csc theta

In a high school, 28% of the students are freshmen 26% are sophomores 22% are juniors and 24% are seniors then enrollment in the school is 1600 students how many freshmen’s are there than juniors
Answer:
96
Step-by-step explanation:
First we can express in numbers how many students are freshman :
(28:100)=0.28 (percent into integer)
Then we multiply this number with 1600
1600*0.28=448 (this is the number of freshman)
Now we do it again with the number of juniors
(22:100)=0.22
1600*0.22= 352
Now we only subtraction these two numbers
448-352= 96
So we now know that there is 96 more freshmens than juniors

which number is an irrational number
A. Square root of 7
B. Square root of 4
C. 0
D. -5
I need help ASAP I will put answer on Brainliest
Answer:
A choice.
Step-by-step explanation:
Irrational number is a number that cannot be written in a fraction form. All square roots are classified as an Irrational number unless can be evaluated to Rational number.
From A choice, you cannot evaluate the square root of 7 into any rational number. Therefore, it is an Irrational number.
B choice, even though there is a square root, but you can still evaluate from square root of 4 to 2.
For C and D, both are integers. Integers are classified to be Rational Number. Therefore, C and D both are rational.
