344.25-150=194.25; 194.25/55.5= 3.5 ~ 3.5 hours

Let x equals hours he was there.

344.25=150.00+55.50x
-150.00 -150.00
----------- ----------
194.25=55.50x

194.25/55.50=55.50x/55.50

3.50=x

Damien wants to deposit $1200 into savings accounts at three different banks: Bank of Chance, Merchant Bank, and Utopian Financi
Luba_88 [7]
If the amount Damien deposits into the Bank of Chance is x, then the amount he deposits into the Merchant Bank is 3*x (as he deposits 3 times as much there). Since 3*x+x=4x, and we know that Utopian Financing's deposit is 20% (or 0.2 by moving the decimal in 20.00 2 places over to the left), 4x*0.2=0.8x=amount he invests in Utopian Financing. Adding them all up, we get x+3x+0.8x=1200=4.8x. Dividing both sides by 4.8, we get 1200/4.8=x=
250 dollars invested in the Bank of Chance. To find 0.8 of 250, we multiply the two to get 0.8*250=200=amount invested into Utopian Financing

Which function has the same y-intercept as the line graphed below?
KatRina [158]

Answer:

D. y + 4 = 2x  

Step-by-step explanation:

The graph has a y-intercept at (0, -4).

A. y=16 - 3x/4

if x = 0, y = 16. FALSE.

B. 24 + 3y = 6x

If x = 0, 24 + 3y =     0

                     3y = -24

                       y =    -8. FALSE.

C. 4y + x = 16

If x = 0, 4y = 16

              y =   4. FALSE.

D. y + 4 = 2x

If x = 0, y + 4 =  0

           y       = -4. TRUE.

y = 4 + 2x has the same y-intercept as the graphed line.

Evaluate the expression for the given value of the variable. d=75 2d+−45d−−−−−√3=
Ahat [919]

Answer:

The expression for the given value of the variable d=75 is, 135

Step-by-step explanation:

Given the expression:

2d+\sqrt[3]{-45d}               ....[1]

We have to find the value for the given expression when d = 75

Substitute the value of d in [1] we have

2(75)+\sqrt[3]{-45(75)}

⇒ 150+\sqrt[3]{-3375}

⇒150-15

Simplify:

⇒135

Therefore, the expression for the given value of the variable d=75 is, 135

If x+3 is a factor of x^3-x^2-10x+A. What is the value of A?
Leno4ka [110]

Answer:

A = 6.

Step-by-step explanation:

Let a denote a constant (a number, rather than a variable like x.)

Let f(x) denote an expression about x (for example,

By the factor theorem, if (x - a) is a factor of f(x), then f(a) = 0. In other words, if all mentions of x in the expression f(x)\! are replaced with a, then the expression should evaluate to zero.

(x + 3) is equivalent to (x - (-3)). That is: a = -3.

Replace all mentions of x in x^3 - x^2 - 10\, x + A by (-3) to get:

(-3)^3 - (-3)^2 - 10\times (-3) + A.

That should evaluate to zero. Therefore: -27 - 9 + 30 + A = 0. Solve for A to get A = 6.
