Answer:
<BCA = 44.4°
Step-by-step explanation:
Reference angle = <BCA = C
Opposite side length = x = 7 cm
Hypotenuse = y = 10 cm
Applying trigonometric ratio, we would have:
[tex] sin(C) = \frac{7}{10} [/tex]
[tex] C = sin^{-1}(\frac{7}{10}) [/tex]
[tex] C = 44.427004 [/tex]
<BCA = 44.4° (to 3 SF)
Which inequality is equivalent to -6x>30
Answer:
x > -5
Step-by-step explanation:
[tex] - 6x > 30 \\[tex] 6x < - 30 \\ \frac{ 6x}{ 6} < \frac{- 30}{ 6} \\ x < - 5[/tex]
The sum of three consecutive integers is 48. Find the integers.
Answer:
15,16 and 17.
Step-by-step explanation:
Let the three consecutive integers are x, x+1,x+2
ATQ,
x+x+1+x+2=48
3x+3=48
Subtract 3 from both sides,
3x+3-3=48-3
3x=45
x = 15
First integer = 15
Second integer = 15+1 = 16
Third interger = 15+2 = 17
Hence, three integers are 15,16 and 17.

The right one will be Brainliest and be given 20 points
Answer:
an-1+8 where a1 =10
Step-by-step explanation:
Since 10 is the starting variable we know that a1 is 10.
The Recursive Formula is [tex]a_n[/tex] = 10 + 8n.
What is Recursive Formula?Any term of a series can be defined by its preceding term in a recursive formula (s).
For example: The recursive formula of an arithmetic sequence is, an = an-1 + d. The recursive formula of a geometric sequence is, an = an-1r.
Given:
Opening amount in bank= $10
Each week he will deposit $8.
On End of first week = 10+ 8= $18
On End of second week = 18 + 8= $26
On End of third week = 26+ 8= $34
Continuing this way we get
By end of n weeks, [tex]a_n[/tex] = 10 + 8n

In the neighborhood park there is a circular grassy picnic area, but half of the grass has died. The city wants to replant the grass, but needs to know the square footage of the damaged area. If the circular picnic area is 150 feet across, what is the square footage of the damaged area? Let pi = 3.14
Answer:
Thus, πr^2 is the equation for the area of a circle, which is equal to 17662.55 if we quantify it.
Then we have half that to get the dead grass area (square miles), which is 8831.25 square feet, then option B is the solution.

p=1/4q+8 make q the subject
Answer:
q = 4p - 32
Step-by-step explanation:
P = 1/4q + 8
Making q the subject
P - 8 = 1/4q
Divide both sides by 1/4
q = (p - 8) ÷ 1/4
= (P - 8) × 4/1
= 4p - 32
q = 4p - 32

Step-by-step explanation:
The set is formed by months of year with indexes larger than 0 and lesser than 12.
The year starts at month 1, which is January, and finishes at month 12, which is December.
Since we want lesser than 12, December is not part of the set. So the answer is given by:

A store display shows two red shirts, four blue shirts, and
four shirts with red and white stripes. The display also
shows four pairs of blue jeans, two pairs of white pants, and
four pairs of red shorts. What is the probability of randomly
selecting an item with white or red on it?
0 2/5
03/5
0 3/10
1/5
Answer:
The probability is 3/5
Step-by-step explanation:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
There are 2 + 4 + 4 + 4 + 2 + 4 = 20 itens.
Of those, 2 + 4 + 2 + 4 = 12 itens have white or red.
So
12/20 = 3/5

Given m∠8 = 123° and m∠11 = 79°, find the measure of each missing angle.
m∠14 =
m∠9 = 79
m∠4 =
m∠2 =
Picture of question is in the attachment below :
Answer:
m∠1= 157°
m∠2= 23°
m∠3= 157°
m∠4= 23°
m∠5= 157°
m∠6= 23°
m∠7= 157°
Step-by-step explanation:
Given that:
m∠8 = 23°
m∠6= 23 ; m∠8 = m∠6 (vertically opposite angles)
m∠5 = m∠7 ( vertically opposite angles)
m∠5 + m∠6 + m∠7 + m∠8 = 360° (sum of angles at a point)
x + 23 + x + 23 = 360
46 + 2x = 360
2x = 360 - 46
2x = 314
x = 314 / 2
x = 157
Hence,
m∠5 = m∠7 = 157°
m∠1 = m∠5 = 157° corresponding angles
m∠4 = m∠8 = 23° corresponding angles
m∠3 = m∠7 = 157° corresponding angles
m∠6 = m∠2 = 23° corresponding angles
