Answer:
A = 20°
AC = 6.6
BC = 2.4
Step-by-step explanation:
Given:
B = 70°
C = right angle = 90°
AB = 7
Required:
A, AC, and BC
Solution:
✔️A = 180 - (90 + 70) (sum of triangle)
A = 20°
✔️Use trigonometric function to find AC:
Refernce angle = 70°
Opp = AC
Hypotenuse = 7
Apply SOH,
sin 70 = Opp/Hyp
sin 70 = AC/7
7 * sin 70 = AC
6.57784835 = AC
AC = 6.6 (nearest tenth)
✔️Use trigonometric function to find Bc:
Refernce angle = 70°
Adj = BC
Hypotenuse = 7
Apply CAH,
cos 70 = Adj/Hyp
cos 70 = BC/7
7 * cos 70 = BC
2.394141 = BC
BC = 2.4 (nearest tenth)
what is the exponent for the expression 6x6x6x6x6x6x6?
Answer:7 is the exponent
Step-by-step explanation:
Answer:
[tex]6^7[/tex]
Step-by-step explanation:
Exponents can be expressed through repeated multiplication, meaning that the amount of times one number is being repeated, would be the same amount as put in an exponent. Therefore :
6 * 6 * 6 * 6 * 6 * 6 * 6
6 is being repeated, therefore it's the constant.
6 is repeated 7 times, therefore the exponent is 7.
[tex]6^7[/tex]

Actually Welcome to the Concept of the linear equation in two variables.
So we have to form two equations to solve this.
Let the number of children be 'x' and number of adults be 'y'.
hence, we get as,
x+y = 630 ..... (1)
and also, to their total cost spending, we get as,
1.5x + 2.25y = 1170 ...... (2)
solving (1) and (2) we get as,
Number of children were = 330
and Number of Adults were = 300

The high temperatures for the first 8 days of January and July are shown in the table. Predict which data set has a greater mean absolute deviation. Justify your answer.
Answer:
January has the greater MAD.
Step-by-step explanation:
The MAD of January is 8. You can figure this out by finding the mean of the data (adding them all together then dividing by the number of data points), then finding the distance between each data point and the mean. You then will add all the distances together, then divide by the number of data points. The MAD of July is 2.5. See above for the process.
you have to find the missing numerator where the question mark is and u have to explain

The daily fee for docking a boat at a marina in port Canaveral is proportional to the length of the boat. The table displays the fee for four different boat lengths. find the constant of proportionality and explain what it means in the context of this problem.
Answer:
Constant of proportionality = 2.25
What this value means is that the ratio between the daily fee for docking a boat at a marina in port and the length of the boat is 2.25
Step-by-step explanation:
We are told that the daily fee for docking a boat at a marina in port Canaveral is proportional to the length of the boat.
Let D be represent the daily fee and let the lent be L.
D ∝ L
Let the constant of proportionality be k.
Thus;
D = kL
k = D/L
For length of 15 ft;
k = 33.75/15
k = 2.25
For length of 17 ft
k = 38.25/17
k = 2.25
For length of 20 ft
k = 45/20
k = 2.25
Foe length of 21 ft
k = 47.25/21
k = 2.25
This means the formula for the relationship between the daily fee and boat length is; D = 2.25L
Thus, D/L = 2.25
What this means is that the ratio between the daily fee for docking a boat at a marina in port and the length of the boat is 2.25

Who earns more money per hour? How much more money does that person make per hour?
A. Holli, $0.75
B. Holli, $0.50
C. Melissa, $0.75
OD. Melissa, $0.50
Answer:
C
Step-by-step explanation:
From the given table, we can calculate the earnings of Melissa.
4 hours' work makes 36 dollars
1 hour work makes=36×1/4=9 dollars
Melissa makes 9 dollars per hour.
Holli makes 8.25 dollars per hour.
So, Melissa makes more money.
9-8.25=0.75
Melissa earns 0.75 dollars more than Holli.
So, the answer is C.
Thomas drew a triangle which has one angle that measures more than
90° and two angles that each measure less than 90°. What kind of
triangle did he draw?
Answer:
obtuse triangle
Step-by-step explanation:
it is obtuse because it needs to have all 3 sides to be acute to be an acute angle and it doesn't have any 90° angles so it has to be obtuse. Also because to be an obtuse it has to have 2 acute angles and 1 obtuse angle. Hope this helps!!
Five times a certain number, minus 5, is equal to 7 more than three times the number. What is the number
Answer:

Find the circumference of a circle that has an area of 153.86 cm.
Answer:
C=[tex]14\pi[/tex] or ≈43.96cm
Step-by-step explanation:
Start by figuring out the Area of the circle to get the radius (r)
Area (A)=153.86 cm
A=[tex]\pi r[/tex]²
153.86=[tex]\pi[/tex]r²
153.86÷[tex]\pi[/tex]=r²
49=r²
√49= r
r= 7cm
Next insert r=7cm into the Circumference equation of a circle
C=2[tex]\pi[/tex]r
C= 2×[tex]\pi[/tex]×7
C=14[tex]\pi[/tex] or C=43.96cm
Find the equation of the line by using y=mx+b
I tried to put the answer but it keeps asking for more
Answer:
Step-by-step explanation:
y=mx+b
m=(y2-y1)/(x2-x1), we have points (-3,6) and (9,-5)
m=(-5-6)/(9-(-3))
m=-11/12 so now we have
y=-11x/12+b, using point (9,-5) we can solve for b
-5=-11(9)/12+b
-5=-99/12+b
b=39/12
y=(-11x+39)/12
That is the line, m=-11/12 and b=39/12 or as a decimal b=3.25. You had b so not sure what the problem is. Though the question in the picture asks what the line is. The line is
y=-11x/12+13/4 so maybe they want the entire function instead of entering what b is.
