Answer:

yearly cost for housing expenses = $11,400, average monthly cost for food = $650

yearly clothing cost = $900,

average monthly cost for transportation= $500,

Yearly cost for insurance & medical= $14,400

yearly cost for emergency fund = $600

average monthly college saving = $50

Step-by-step explanation:

Yearly housing = monthly cost * 12 = 950 * 12 = 11400

Food, monthly = 7800 /12 = 650

Clothing, yearly = 75 * 12 = $900

Monthly transport = 6000 / 12 = $500

Insurance and medical = 1200*12 =14400

Emergency fund = $50 * 12 = $600

College saving = $600 / 12 = $50

ZE and ZF are vertical angles with mZE = 8x + 8 and mZF = 2x +38. What is the value of x?

Dovator [93]

Answer:

Since ZE and ZF are vertical angles, they are congruent.

8x+8 = 2x+38

8 = 2x-8x+38

8 = -6x+38

8-38 = -6x

-30 = -6x

x = -30/-6

x = 5

1 cm 2 cm What is the area of the composite figure? cm 8 cm

bogdanovich [222]

Answer:

Answer:Option D is correct.Step-by-step explanation:We are given with a solid figure with cuboid in base and square based pyramid in top.we have to find Surface of the figure.Surface Area = Curved surface ares of cuboid + area of base of cuboid + lateral surface area of pyramid.Length of the cuboid, l = 8 cmwidth of the cuboid , w = 8 cm height of the cuboid , h = 11 cm Lateral surface area of pyramid = 4 × Area of a triangle Base of triangle , b = length of cuboid = 8 cmHeight of the triangle ,H = 8 cmSurface Area = 2 × h × ( l+w ) + l × b + 4 × 1/2 × b × H = 2 × 11 × ( 8 + 8 ) + 8 × 8 + 2 × 8 × 8 = 22 × 16 + 64 + 128 = 352 + 192 = 544 cm²Therefore, Option D is correct.

Help please asap ASAP ASAP ASAP PLEADEEEEEEEEE

SOLUTION OF TRIANGLE:

a i) use this formula, a² = b² + c² - 2bc cos A

a² = 8² + 10² - 2(8)(10) cos 60
= 84
a = 9.17 cm

UW = 9.17 cm

ii) use formula no 12 as attached :

sin
to solve this,

( sin 40 / 11 ) x 9.17 = 0.5358511

press shift sin on ur calc & the answer is :

FUNCTION

a) f(x) = x-3
g(x) = x²-1

i) f(6) = 6-3

substitute x with the value given in the bracket into equation

f(6) = 6-3
= 3

ii) to do inverse function use this formula :

u = f(x)
u = x - 3

and then make x as the subject

x = u + 3

after that, just change u to x

f-1(x) = x + 3

iii) f [ g(2) ] = f [ g(-2) ] = 0

g(2) = (2)² - 1 g(-2) = (-2)² - 1

= 4 - 1 = 4 - 1
= 3 = 3

f(3) = 3-3
= 0

How many solutions does the equation 3x-2x+4=2+x+2 have?

ladessa [460]

Answer:

infinitely many solutions

Step-by-step explanation:

3x - 2x + 4 = 2 + x + 2

x + 4 = x + 4

x = x

x = x is a true statement for every value of x, so there is an infinite number of solutions.

Answer: infinitely many solutions
