Ming drew a triangle. The sum of the angles of the triangle is 180º. In Ming’s triangle, B is twice the measure of A, and angle

C is 5º greater than four times A. The system of equations below can be used to find the measure of the three angles, where a represents the measure of A, b represents the measure of B, and c represents the measure of C. a + b + c = 180 2a = b 4a + 5 = c Which matrix represents the measure of each angle in Ming’s triangle?

Let
a--------------> <span>represents the measure of angle A
</span>b--------------> represents the measure of angle B
c--------------> represents the measure of angle C

we know that

a+b+c=180-----------> equation 1
b=2a------------> equation 2
c=4a+5--------> equation 3

<span>I substitute 2 and 3 in 1
</span>a+(2a)+(4a+5)=180-----------> 7a+5=180--------> 7a=175--------> a=25°
a=25°
b=2a----------> b=2*25---------> b=50°
c=4a+5---------> 4*25+5---------> c=105°

the <span>matrix that represents the measure of each angle in Ming’s triangle
</span>is [25°, 50°. 105°]

the answer is [25°, 50°. 105°]

If 36^12-m=6^2m what is the value of m??
skad [1K]

Answer:

m=6

Step-by-step explanation:

if 36^12-m=6^2m , find the value of m

36^{12-m}=6^{2m}

To make the exponents equal , we need to get the same base.

The base of both sides of equation are not same.

36 can be written as 6^2

6^{2(12-m)}=6^{2m}

6^{24-2m}=6^{2m}

now base of both sides are same . so we equate the exponents

24-2m= 2m

add 2m on both sides

24=4m

divide by 4 on both sides

6=m

The value of m is 6

marysya [2.9K]

Answer:

Step-by-step explanation:

Household.          Year 2010.         Year 2015.           Difference

Adderley.              47,200               58,200.                11,000

Bonniville.              52,900.             62,400.                9,500

Clay City.               44,600.              57,600.                13,000

Daletown.              41,500.               54,000.               12,500

Percentage increase for Adderley = 11,000/47,200 * 100= 23.3%

Percentage increase for Bonniville = 9,500/52,900 * 100= 17.96%

Percentage increase for Clay City = 13,000/44,600 * 100= 29.15%

Percentage increase for Daletown = 12,500/41,500 * 100= 30.12%

We can now see that Bonniville is the city with the lowest rate of increase in median household income.
