Answer:
C
Step-by-step explanation:
We are given that:
[tex]\displaystyle \sin y^\circ = \frac{s}{8}\text{ and } \tan y^\circ = \frac{s}{t}[/tex]
And we want to find the value of:
[tex]\displaystyle \sec y^\circ[/tex]
Recall that tan(θ) = sin(θ) / cos(θ). Since sec(θ) = 1 / cos(θ), tan(θ) = sin(θ)sec(θ). Substitute:
[tex]\displaystyle \sin y^\circ \sec y^\circ = \frac{s}{t}[/tex]
Substitute:
[tex]\displaystyle \frac{s}{8}\sec y^\circ =\frac{s}{t}[/tex]
Solve for secant:
[tex]\displaystyle \sec y^\circ = \frac{8}{t}[/tex]
Hence, our answer is C.
Answer:
c. sec y° = 8/t

Answer:
a.) terry didn't line up the triangle correctly. 4/y = 20/18
b.) (20+16)/18
Step-by-step explanation:
for part a, you have to make sure the angles line up correctly (the angle with one tick mark lining up with the angle with one tick mark, the angle with two tick marks lining up with the angle with two tick marks, etc.)
for part b.) you just put the proportional lengths of the bigger triangle in for the lengths of the smaller triangle.

for first question your pattern is 3x+4 then 3(10)+4=34.. I mean your answer is part c
in second picture if your mean is 7 question, the answer is part 1. w=p/2_125 can not be the answer.
if your mean is 8 question, it's answer is point S. because x=5 &y=-25 then 5-(-25)=+30 it means point S.
but if your mean is the 6 question,it's answer is part 1..it means 3e+5c+2(1)

Answer:
Yes Ella has enough to make 30 mince pies
Step-by-step explanation:
to make 36 mince pies you will need
400g of butter
500g of flour
300g of sugar
500g of mince meat
2 eggs
Ella has 1000g of butter
1000g of flour
500g of sugar
600g of meat
6 eggs
these ingredients are more than enough because
1000g-400g=600g-butter
1000g-500g=500g flour
500g-300g=200g sugar
600g-500g=100g mince meat
6-1= 5 eggs
if she were to follow the 36 pie recipe, which is two times the 18 pie recipe
but like I don't know, because it says a recipe for 18 mince pies, but in the box it says 12
Rationalise the denominator of
2√3 + 3√2/4√3 +√2
Answer:
[tex]\frac{9+ 5\sqrt{6} }{23}[/tex]
Step-by-step explanation:
2√3 + 3√2 * 4√3 -√2
4√3 +√2 4√3 -√2
multiply by conjugate
2√3 + 3√2 * 4√3 -√2 = 18 +10√6 = 9 +5√6
4√3 +√2 4√3 -√2 46 23
Answer:
Step-by-step explanation:
To rationalize the denominator, multiply the numerator and denominator by the conjugate of the denominator.
Conjugate of 4√3 + √2 is 4√3 - √2
(2√3 +3 √2)(4√3 - √2) = (2√3 * 4√3) - (2√3*√2) + (3√2*4√3) -(3√2*√2) {Use FOIL method}
= 8*3 - 2*√6+12√6 -3*2
= 24 -2√6 +12√6 - 6
= 24 - 6 + (-2+12)√6)
= 18 + 10√6

What is the common ratio of this sequence?
Answer:
D. 5
Step-by-step explanation:
a geometric sequence is defined that any item of the sequence is created by multiplying the previous item of the sequence with a constant factor (it is the same factor for every item in the sequence).
so, we have the starting value
a1 = 3
then
a2 = 15
what is a multiplication factor to go from 3 to 15 ?
well, 5. I need to multiply a1 by 5 to get a2.
and this continues.
a3 = a2×5 = 15×5 = 75
a4 = a3×5 = 75×5 = 375
and so on.
the ratio of the sequence is simply the relation of one sequence item to the previous one :
an/an-1
and that is here for the described reasons 5.

Answer:
36 units squared
Step-by-step explanation:
10 times 10 - 4 times 4 = 100-16 = 84, take the square root of 84 = 9.12 which rounds to 9, now that we found the height, we use the area of a triangle formula, A=bh/2, so the base is 8 times height 9 = 72 divided by 2 = 36

Solve the system of equations.
6x – Зу = 3
-2x + y = 14
1.What number would you multiply the second equation
by in order to eliminate the x-terms when adding to the
first equation?
2.What number would you multiply the first equation by in
order to eliminate the y-terms when adding to the
second equation?
Answer:
1. Multiply by 3
2. Multiply by 1/3
Step-by-step explanation:
6x - 3y = 3
-2x + y = -14
1. In order to eliminate the x-terms, they would both have to equal the same number with opposite signs (positive and negative). Since we are only touching the second equation, how can we get from 2 to 6? We can multiply 2 by 3 to get to 6 (negative 6 in the end.) This would result as follows:
6x - 3y = 3
-6x + 3y = 42
2. In order to eliminate the y-terns through multiplying with the first equation, we have to figure out how to make 3y into 1y. We can do this by adding its reciprocal, 1/3. 1/3 × 3 = 1. This would result as follows:
2x - y = 1
A woman's salary is increased by 20%. A week later her company loses one of its best customers and her salary is reduced by 35%. If her salary is now $4446, what was her original salary?
Answer:
$5472
Step-by-step explanation:
Set up a reverse ratio for each change:
4446/x = 65/100
65x = (4446) x (100)
65x = 444,600
x = 6840
Before her salary was reduced by 35%, she was earning $6840.
x/6840 = 20/100
100x = (6840)(20)
100x = 136,800
x = 1368 = 20%
$6840 - $1368 = $5472
Mark invests $8,008 in a retirement account with a fixed annual interest rate of 2% compounded 6 times per year. What will the account balance be after 16 years?
Please help i need the answer by tomorrow!
Given:
Principal value = $8,008
Rate of interest = 2% compounded 6 times per year.
Time = 16 years
To find:
The account balance after 16 years.
Solution:
The formula for amount is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is principal, r is the rate of interest, n is the number of times interest compounded in an year and t is the number of years.
Putting [tex]P=8,008, r=0.02,n=6,t=16[/tex] in the above formula, we get
[tex]A=8008\left(1+\dfrac{0.02}{6}\right)^{6(16)}[/tex]
[tex]A=8008\left(\dfrac{6.02}{6}\right)^{96}[/tex]
[tex]A=11022.1721148[/tex]
[tex]A\approx 11022.17[/tex]
Therefore, the account balance after 16 years is $11022.17.

Please help me find this angle
Answer:
x = 78
Step-by-step explanation:
We can find angle y
D + B + y = 180 since the sum of the angles of a triangle are 180
31+47+ y =180
78+y = 180
y = 180 - 78
y = 102
x+y = 180 since they form a straight line
x + 102 = 180
x = 180-102
x = 78

Your business of household products manufacturing is about to start a venture to producing self-squeezing mops with an initial budget of Php 8,500,000.00. To be competitive in the market, the board plans to sell one unit for only Php 600.00 with a computed variable cost for each of Php 237.00. How many units of the mops shall represent the breakeven point?
Answer:
break-even point in units = 23,416 units (Approx.)
Step-by-step explanation:
Given:
Initial budget of Php = 8,500,000
Sales price of Php = 600
Variable price of Php = 237
Find:
break-even point in units
Computation:
break-even point in units = Initial budget of Php / [Sales price of Php - Variable price of Php]
break-even point in units = 8,500,000 / [600 - 237]
break-even point in units = 8,500,000 / 363
break-even point in units = 23,415.978
break-even point in units = 23,416 units (Approx.)

Find the values of p and q for which the following system of equations has infinitely many
solutions:
2x + 3y = 7
(p + q + 1)x + (p + 2q + 2)y = 4(p + q) + 1
Answer:
p = 3
q = 2
Step-by-step explanation:
they have infinitely many solutions, if they are basically the same equations. in other words, when they can be combined/reduced into a statement of tautology, a statement that is always true, no matter what.
like 15 = 15 or 8x = 8x
now we need to aim for creating the same (or multiples of the same) factors in the original equation 2 as in the original equation 1.
in other words we find the p and q, where we get the same ratios between the factors of squadron 1 and equation 2.
2/(p+q+1) = 3/(p+2q+2) = 7/(4p +4q +1)
p+q+1 = 2/3 × (p+2q+2) = 2/7 × (4p + 4q + 1)
3p + 3q + 3 = 2p + 4q + 4 = 6/7 × (4p+4q+1)
21p + 21q + 21 = 14p + 28q + 28 = 24p + 24q + 6
7p - 7q = 7
p - q = 1
p = 1 + q
14(1+q) + 28q + 28 = 24(1+q) + 24q + 6
14 + 14q + 28q + 28 = 24 + 24q + 24q + 6
42 + 42q = 30 + 48q
12 = 6q
q = 2
p = 1 + 2 = 3
