Answer:

dirk =13.25 hours

charlie =11 75 hours

Step-by-step explanation:

c+d=25------(1)

d-1.5=c-----(2)

from (1),

c+d=25

c=25-d-----(3)

substitude (3) into (2)

d-1.5=c

d-1.5=25-d

2d=26.5

d=13.25

if d=13.25 hours

c+d=25

c+13.25=25

c=25-13.25

c=11.75

Help plzzzzzzz.... I don’t understand this

saveliy_v [14]

Answer:

Surface area is the sum of all of the areas of the faces in a solid figure. To find the surface area, we must be able to calculate the area of each face and then add these areas together. A net is a two-dimensional diagram of a three-dimensional figure. With a net, we can see each face of the pyramid more clearly. To find the surface area, we need to calculate the area for each face in the net, the sides and the base. The side faces of a pyramid are always triangles, so we use the area formula for triangles to calculate their area: A=1/2 bh (BASE TIMES HEIGHT)..

Change 1/50 to a decimal

Tems11 [23]

The answer is 0.02

All you have to do is divide 1 by 50. You can think of it as if it was divided by 100. If you multiply the numerator and denominator by 2 you get 2/100 which is 0.02

Help me please. I'm very confused

To solve this problem we must find 5% of 1418 and 4% of 1418
which is
$5 \div 100 \times 1418 \\ \ \\ 4 \div 100 \times 1418$

so that would be 70.9 house extra in the first year and 56.72 extra in the second year respectively.
so to find the total number of houses we must add 70.9 + 56.72 + 1418 which gives us 1545.62
at the last it is mentioned for us to round our answer to the nearest

they are asking us for the total number whole number
which is 1546
so there would be 1546 houses in the second year.

State the y-coordinate of the y-intercept for the function below.

marta [7]

Answer:

Step-by-step explanation:

y-intercept is defined as the point where the graph crosses the y-axis. The value of x coordinate at this point is zero, as along entire y-axis, the value of x coordinate is always zero. So substituting x = 0 in the function will give us the y-coordinate of the y-intercept of the given function.

$f(x)=x^{3}-x^{2} -x+1$

Substituting x = 0 in this function, we get:

$f(0)=0^{3}-0^{2}-0+1=1$

Thus, the y-coordinate of the y-intercept is 1. Therefore the y-intercept of the function in ordered pair will be: (0, 1)
