7 0

Answer:

a = 2

Step-by-step explanation:

Given the expression:

2111_{four} = 150

This can be expressed as:

(2*4^3)+(1*4^2)+(1*4^1)+(a*4^0) = 150\\128+16+4+a = 180\\148 + a = 150\\a = 150 - 148\\a = 2

Hence the value of a is 2

Whats an equation for (0,75) (7,40) in slope intercept form
Molodets [167]

The slope-intercept form: y = mx + b.

m - slope, b - y-intercept

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (0, 75) → y-intercept (b = 75), and (7, 40).

Substitute the coordimates of the points to the formula of a slope:

m=\dfrac{40-75}{7-0}=\dfrac{-35}{7}=-5

<h3>Answer: y = -5x + 75.</h3>

Mango mixed 24 ounces of blue paint with 16 ounces of red paint to create a new purple color. In order to create 72 more ounces
mamaluj [8]

Answer: 28.8 ounces of red paint

Step-by-step explanation:

The total amount of paint created the first time Mango mixed colors was:

= 24 + 16

= 40 ounces of purple color

For 40 ounces of purple, 16 ounces of red was needed. Proportion is therefore:

= 16/40

If one wants 72 ounces of purple therefore:

= Proportion of red used * 72 ounces

= 16/40 * 72

= 28.8 ounces of red paint

Find the size of each of 66 payments made at the end of each year into a 88​% rate sinking fund which produces ​$36000 at the en
Assoli18 [71]

Answer: $7787.99

Step-by-step explanation:

We know that the formula to find the periodic payment on an annuity is given by :-

P=\dfrac{r(PV)}{1-(1+r)^{-n}}, where PV is the present value , r is the rate of interest ( in decimal ) and n is the number of payments.

Given : Present value : $36000

Rate of interest = 8%=0.08

Time period = 6 years

Then , the periodic payment will be :-

P=\dfrac{(0.08)(36000)}{1-(1+0.08)^{-6}}\\\\\Rightarrow\ P=\dfrac{2880}{0.3698}\\\\\Rightarrow\ P=\$7787.99

Hence, the payment size is $7787.99.
