Answers
Answer:
D. -[tex]\sqrt{17}[/tex]/8
Step-by-step explanation:
Draw a right triangle such that cos (theta) = 8/9. That means the hypotenuse = 9 and the adjacent side to theta = 8
Use the Pythagorean theorem to find the opposite side to theta
[tex]\sqrt{9^{2} - 8^{2} } = \sqrt{81 - 64} = \sqrt{17}[/tex]
tan (theta) = [tex]\sqrt{17}[/tex]/8
Since theta is in quadrant IV, the tan is negative. So, tan (theta) = -[tex]\sqrt{17}[/tex]/8
After considering the equation. Assuming 8 is an angle in quadrant iv, the value of tan(Ф) is:√17/8
Value of tan(Ф)Given:
Equation=cos(Ф)=8/9
Using pythagorean theorem formula
H²=P²+B²
Where:
B=8
H=9
Let plug in the formula
P²=9²-8²
P=√81-64
P=√17
Since 8 is an angle in quadrant iv. Hence:
Value of TanФ=√17/8
Inconclusion the value of tan(Ф) is:√17/8

r= 3 in.
h = 5 in.
Answers
Answer:
[tex]A=150.72\ in^2[/tex]
Step-by-step explanation:
Given that,
The radius of candle, r = 3 inches
The height of the candle, h = 5 inches
We need to find the surface area of the candle. It is in the form of a cylinder whose surface area is given by :
[tex]A=2\pi r(r+h)[/tex]
Put all the values,
[tex]A=2\times 3.14\times 3\times (3+5)\\\\A=150.72\ in^2[/tex]
So, the surface area of the candle is equal to [tex]150.72\ in^2[/tex].

A school sells adult play tickets for $7 and student tickets for the play for $4. If the school sold
420 student tickets, how many adult tickets were sold if the total sales for the play were $3010.
Answers
Answer:
190 adult tickets.
Step-by-step explanation:
Well,
420 × 4 = 1,680
3,010 - 1,680 = 1330
1330 ÷ 7 = 190.
So 190 adult tickets to the play were sold.

note : the figure shown in the image attached
helppppppp
Answers
Answer:
E. (7, 5)Explanation:
vertices C and D have the same coordinate x and x of D = 7
hence
x of C = 7
vertices A and D have the same coordinate y and y of D = 2
hence
m = 2
and
m+3 = 2+3 = 5
and since vertices B and C have the same coordinate y and y of B = 5
hence
y of C = 5
thus
coordinates x, y of C: (7, 5)
Which term of series1 +4+7+10+...is43
Answers

d = a2 - a1
d = 7 - 4
d = 3
an = 43
an = a + (n - 1)d
43 = 4 + (n - 1) 3
43 = 4 + 3n - 3
43 = 1 + 3n
43 - 1 = 3n
3n = 42
n = 42 ÷
n = 14
So, 14th term is 43

in the bag, there are certain number of toy- blocks with alphabets A,B,C and D written on them. The ratio of blocks A:B:C:D is 4:7:3:1. if the number of A blocks is 50 more than the number of C blocks, what is the number of B blocks?
Answers
Let us consider the common ratio to be ‘x’.
So, toy blocks with alphabet A is 4x and
toy blocks with alphabet B is 7x and
toy blocks with alphabet C is 3x and
toy blocks with alphabet D is x
Again, the number of ‘A’ blocks is 50 more than the number of ‘C’ blocks.
As no. of ‘A’ and ‘C’ blocks are 4x and 3x respectively.
So,
4x=50 + 3x
x=50
Thus, the number of ‘B’ blocks is 7x = 7(50) = 350
350 is the required number.
9514 1404 393
Answer:
350
Step-by-step explanation:
There are 4 ratio units of A blocks and 3 ratio units of C blocks, so 1 more ratio unit of A blocks than of C blocks. That 1 ratio unit corresponds to 50 blocks, since there are 50 more A blocks than C blocks.
There are 7 ratio units of B blocks, so the number of B blocks is ...
7×(50 blocks) = 350 blocks . . . . . number of B blocks

Answers
Therefore, the product of 5 and fraction (-2/3) is -10/3.
What is fraction?A fraction is a number that represents a part of a whole. It consists of two numbers separated by a horizontal or diagonal line, called a fraction bar. The number above the fraction bar is called the numerator, and the number below the fraction bar is called the denominator. The numerator represents the part of the whole that we are interested in, and the denominator represents the total number of equal parts into which the whole is divided. Fractions can be used to represent ratios, proportions, percentages, and many other mathematical concepts. They can be added, subtracted, multiplied, and divided using specific rules and procedures. Fractions can be proper (when the numerator is less than the denominator), improper (when the numerator is greater than or equal to the denominator), or mixed (when the fraction is represented as a whole number and a proper fraction).
Here,
To find the product of 5 and (-2/3), we simply multiply the two numbers:
5 x (-2/3) = -10/3
