Answer:
a=-13
Step-by-step explanation:
-50=6a+28
isolate the a
-50-6a=28
-6a=28+50
-6a=78
divide both sides by -6
a=-13

In ΔQRS, q = 9.4 cm, r = 8 cm and ∠S=151°. Find ∠Q, to the nearest 10th of a degree.
9514 1404 393
Answer:
15.7°
Step-by-step explanation:
The law of cosines can be used to find side s:
s² = r² +q² -2rq·cos(S)
s² = 8² +9.4² -2(8)(9.4)·cos(151°) ≈ 283.903
s ≈ 16.849
Then the law of sines can be used to find angle Q.
sin(Q)/q = sin(S)/s
sin(Q) = (q/s)sin(S)
Q = arcsin(q/s·sin(S)) = arcsin(9.4/16.849·sin(151°)) ≈ 15.692°
Angle Q is about 15.7°.

20 is 4/7 of what number?
Answer:
35
Step-by-step explanation:
The population of Miami-Dade County in Florida in 2010 was 2, 496, 435 and the land area was 1, 898 square miles. The population increased by 7.9% in 2015. Part 1: To the nearest whole number, find the population density, in people per square mile, for Miami- Dade County in 2015
The population density of the city which is the ratio of population size and the land area is 1419 people per square mile.
The initial population = 2496435The percentage increase in population = 7.9%Land Area = 1898 mi²The population of the city on 2015 can be calculated thus :
(1 + percent increase) × initial population (1 + 0.079) × 2496435 = 2693653.365 peopleThe population of a city is calculated using the relation :
Population density = Population / Land Area Population density = 2693653.365/1898 Population density = 1419.21Therefore, the population density is 1419 people per square mile.

Answer:

Step-by-step explanation:
Determine the measure of the indicated
exterior angle in the diagram.
Answer: 110 degrees
Triangle sum theory tells us that all the internal angles are equal to 180.
Meaning, we can solve 2x+3x+3x+4=180 for x
x=22
Then solve for 3x+4, which equals 70.
Last step, take 70 from 180 to find the external angle!
110 :)
Answer:
Exterior angle is equal to 110
Step-by-step explanation:
So to find the exterior angle, you must find the interior angle first.
You know that all 3 angles within the triangle must equal to 180 degrees, so what we can do is set up this equation to reflect that statement:
2x+3x+(3x+4) = 180
Group like terms:
8x+4=180
Solve for x:
8x = 176
x = 22
We can double check to see this matches up with all of the other angles inside:
2x = 44
3x = 66
3x+4 = 70
44 + 66 + 70 = 180
We also know that a straight line is 180 degrees
So, ? = 180 - 70
? = 110 degrees
what is 34/9 in simplest form?
3 7/9
Step-by-step explanation:
34/9
= 34 ÷ 9 = 3 remain 7
= 34 = 9 × 3 + 7
so
34/9
= 3 7/9
Answer:
34/9 is already in it's simplest form but can be written as a decimal: 3.777778
Step-by-step explanation:
1. Find the HCF of both numbers which is 1
2. Divide them both by the HCF
3. 34/1 = 34
4. 9/1 = 9
5. Therefore there is no simpler fraction but you can write it as a decimal.

you have 120 cows and 90% of them are female how many female cows do you have
Answer: 108
Step-by-step explanation:
If 90% are female, that means that female = 90% of 120, or 90/100 x 120
90/100 x 120 = 108, meaning that there are 108 female cows.
