Answer:V=whl

Step-by-step explanation:

all you have to do is multiply width times length times height

1 1/2 × 1 1/2 × 1 1/2= 3/2 × 3/2 × 3/2 = 27/ 8

simplify to

Answer:

[tex]AB = 3.6[/tex]

Step-by-step explanation:

Given

The attached graph

Required

Distance AB

From the graph:

[tex]A = (-2,1)[/tex]

[tex]B = (1,-1)[/tex]

The distance is:

[tex]AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

[tex]AB = \sqrt{(-2 -1)^2 + (1- -1)^2}[/tex]

[tex]AB = \sqrt{(-2 -1)^2 + (1+1)^2}[/tex]

[tex]AB = \sqrt{13}[/tex]

[tex]AB = 3.6[/tex]

Answer:

do you have a picture of the question

Answer:

(3,7)

Step-by-step explanation:

Use a system of equations to solve for x and y which would be the only points where the two lines intersect

x+y=10

y=2x+1

since y=2x+1 you can put 2x+1 for y

so x+2x+1=10

3x+1=10

3x=9

x=3

put that back into x+y=10

3+y=10

y=7

So the only point where those two lines intersect is (3,7)

Hope that helps :)

a=1.5 a=-2

n=-1.5 n=4

Step-by-step explanation:

(a) (b) (c)

10a2+5a-30

x=-b+-√b2-4ac/2a

a=-5+-√(5)2-4(10)(-30)/2(10)

a=-5+-√25+1200/20

a=-5+-√1225/20

a=-5+√1225/20

a=1.5

a=-5-√1225/20

Answer:

C

Step-by-step explanation:

Answer:

It can be shown that opposite sides of parallelogram must be congruent , that opposite angles are also congruent , and that consecutive angles are supplementary . ...

The perimeter of a parallelogram is the sum of the lengths of its four sides. ...

Therefore, the perimeter is 6+10+6+10 or 32 cm.

Step-by-step explanation:

Answer:

Perimeter is always the same, add the outer lengths of all the sides. A+B+A+B=T

Or

2(A+B)

Area is just B * H when you have the height available.

You can also use a trig function A = ab sin (x)

Answer:

A = 14 units ²

Step-by-step explanation:

Hello There!

The polygon shown is a triangle

The first step is to find the formula for area of a triangle

[tex]A=\frac{1}{2} bh[/tex]

where b = base and h = height

the following dimensions are given

base = 7 and 4 = height

so all we have to do is plug in the values into the formula

[tex]A=\frac{1}{2} 7*4\\7*4=28\\\frac{1}{2} 28=14\\A=14[/tex]

so we can conclude that the area of the polygon is 14 units ²

Answer:

area of polygon =area of TRIANGLE =

1/2 base×height =1/2×7×4=14 units²

Answer:

1/48 or .2083

Answer:

y=24,x=20/3

[tex]y = 3x + 4[/tex]

[tex]8 = 6 \times 2y[/tex]

[tex] 2y = 8 \times 6 [/tex]

[tex]y = 24[/tex]

[tex]24 = 3x + 4[/tex]

[tex] - 3x = 4 - 24[/tex]

[tex] x = \frac{20}{3} [/tex]

Answer:

C,A,D,D

Step-by-step explanation:

Answer:

Option D

Step-by-step explanation:

Rate of change of a linear function between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Rate of change 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the given table,

Rate of change of the function between (-2, 6) and (-4, 9),

Rate of change 'm' = [tex]\frac{9-6}{-4-(-2)}[/tex]

                           m = [tex]\frac{3}{-2}[/tex]

Initial value = y-intercept

Let the equation of the line passing through a point (h, k) is,

y - k = m(x - h)

If a point (-2, 6) is lying on the graph of the function,

y - 6 = [tex]-\frac{3}{2}(x+2)[/tex]

y = [tex]-\frac{3}{2}x-3+6[/tex]

y = [tex]-\frac{3}{2}x+3[/tex]

Y-intercept of the function = 3

Therefore, initial value of the function = 3

Option D is the answer.

Answer:

Q3 = 30

Step-by-step explanation:

minimum value = 5

Q1 = 20  (this is the median of the lower half of data)

Median (sometimes called Q2) = 25

Q3 = 30 (this is the median of the upper half of data)

maximum value = 45

Answer:

C. 20 Ft.

Step-by-step explanation:

Using The Pythagorean Theorem, a²+b²=c² , insert the known variables into the equation.

18.7²+6²=c²

This gives you 385.69 + 36 = 385.69.

Next, square the result to find the missing side length.

[tex]\sqrt{385.69[/tex]

The answer comes out to around 19.6, which can be rounded up to 20ft.

Answer:

df(t)/dt = 10 - 0.8f(t)

Step-by-step explanation:

The net rate of change, df(t)/dt = rate in - rate out

The rate in = rate litter forms on ground = 10 g/cm²/yr

Since f(t) is the amount of litter present at time, t, in g/cm² the rate out = rate of decomposition = the percentage rate × f(t) = 80% per year × f(t) = 0.8f(t) g/cm²/yr

Since df(t)/dt = rate in - rate out

df(t)/dt = 10 - 0.8f(t)

So the desired differential equation is

df(t)/dt = 10 - 0.8f(t)

Answer:

C. 73 and 73

Step-by-step explanation:

An isosceles triangle has two angles that are the same, that narrows it down to C and D. The question states that there is only one 34° angle so it has to be C.

Answer:

C. 73° and 73°

Step-by-step explanation:

We know that the sum of interior angles in a triangle is equal to 180° and

Isosceles triangles has two angles with same measurement

it stated in the question that exactly one angle has measure of 34°

So the other two angles must be equal for the triangle to be isosceles

180 - 34 = 146 and this divided by 2

73° and 73° is the answer.
