Pls help I’m rlly confused. The question says “find the value of x using complementary angels” ty <3

Arturiano [62]

Answer:

x=83. please look below for explanation. if anything isn't clear, please ask

Step-by-step explanation:

so complementary means adding up to 90 degrees in math. in this particular equation, you have to make sure that both (x-18) and 25 add up to 90.

if that other side is 25 degrees, the other side must be 65 because 90-25=65.

so now you have to set those equal to each other like this:

65 = (x-18) now just solve for x

add the 18 to the other side. the -18 and +18 cancel.

x=83

so to test and to see if that is right, we can do

83-18 = 65

does 65+25 equal 90? yes

therefore, x=83

Find three consecutive odd integers such that 5 times the sum of all three is 42 more than the product of the first and second i

maxonik [38]

The three integers are x, x+2, x+4

5(3x+6)=42+x(x+2)
15x+30=x^2+2x+42
x^2 - 13x +12=0
(x-12)(x-1) = 0
x = 12 or 1
since the integers have to be odd we exclude 12

integers are 1,3,5

In this exercise, we estimate the rate at which the total personal income is rising in the Richmond-Petersburg, Virginia, metrop

babymother [125]

Answer:

The rate at which the total income is increasing is$1627415600

Step-by-step explanation:

From the given data

Population in the area=P=961400

The rate of increase in population=dP/dt=9200

The Average Income=I=$30593

The rate of increase in Average Income=dI/dt=$1400

Now the total income is given as

Total Income=TI=PI

So the rate of increase of total personal income is given as $\frac{d}{dt}(PI)$

From the product rule of derivatives

$\frac{d}{dt}(P*I)=I*\frac{dP}{dt}+P*\frac{dI}{dt}$

Here

I is the Average Income which is given as $30593

dI/dt is the rate of increase of income which is given as $1400.

P is the population of the area which is given as 961400

dP/dt=9200 is the rate of increase of population which is given as 9200

By substituting the values,

$\frac{d}{dt}(P*I)=I*\frac{dP}{dt}+P*\frac{dI}{dt}\\\frac{d}{dt}(P*I)=30593*9200+961400*1400\\\frac{d}{dt}(P*I)=\$1627415600$

So the rate at which the total income is increasing is$1627415600

Martha has a healthcare plan with $20 co-pays to see doctors, $10 co-pays for prescription drugs, and an annual deductible of $1

Kazeer [188]

Given:
20 co-pays to see doctor
10 co-pays for prescription drugs
1,000 annual deductible.

3 doctors with the following bills - 857, 139, 271
2 prescription drugs - 40 and 27

Co-pay means that Martha should pay a fixed amount to see doctors and for prescription drugs.

Martha saw 3 doctors so her total co-pay is 60. (20 x 3)
Martha has 2 prescription, so her total co-pay is 20. (10 x 2)

Martha's share of the bills in May is 80. (60 + 20)
