y=-5x 2 + 15x - 10 fffffft

Answer:

B

Step-by-step explanation:

The problem is simple because they use powers of 10. When something is multiplied by a power of ten, it is essentially moving the decimal point over for every power.

9.46x10^12= 9460000000000

4.0x10^13= 40000000000000

Although 4 itself is less than 9.46, since is is being multiplied by 10^13, it will be one decimal place bigger.

Answer:

0.17

Step-by-step explanation:

0.017 times 10 will equal to 0.17 as you will need  to move the decimal point forward by one

Answer:

length = 15 cm

Width = 12 cm

Step-by-step explanation:

Let width = w cm

Length = w + 3

Perimeter of rectangle = 54 cm

2 * (length + width) = 54

2 * (w+3 + w) = 54   {Add like terms}

2 *(2w + 3) = 54

2*2w + 2 * 3 = 54

4w + 6   = 54

Subtract 6 form both sides

4w = 54 - 6

4w = 48

Divide both sides by 4

w = 48/4

w = 12 cm

Length = 12 + 3= 15 cm

Answer:

Length = 15cm

Step-by-step explanation:

let width be x

length = x+3

Perimeter = 2(l + b)

Perimeter = 54cm

equating:

2(x + x + 3) = 54

2(2x +3) = 54

4x + 6 = 54

4x = 54 - 6

4x = 48

x = 48/4 = 12

width = x = 12cm

length = x +3 = 12 + 3 = 15cm

Answer:

130 meters squared

Step-by-step explanation:

14-6=8

8*13/2=52

14*13=182

182-52=130 meters

Answer:

130 square metres

Step-by-step explanation:

The shaded area is a trapezium.

Therefore, the rule for its area is base1+base2/2xh

base1=6

base2=14

height = 13

Therefore, 6+14/2 x 13

= 130

Answer:

1258

Step-by-step explanation:

SI = (P x R x T) / 100

SI = Simple Interest

P = Principal

R = Rate

T = Time

SI = (850 x 8 x 6)/100

=> SI = 85 x 8 x 6 /10

=> SI = 680 x 6 /10

=> SI = 68 x 6

=> SI = 408

The total amount after 6 years = Principal + Simple Interest

=> Total Amount = 850 + 408

=> Total Amount = 1258

After 6 years, the amount in account is 1258.

Answer:

[see below]

Step-by-step explanation:

Volume of a triangular prism is: [tex]V=\frac{1}{2}bhl[/tex]

We are given the base of 5, the length of 12, and the height of 8. All measurements are in meters.

[tex]V=\frac{1}{2}(5*12*8)\\\\V=\frac{1}{2}(480)\\\\V=240[/tex]

The volume of the prism should be 240 square meters.

Answer:

V = 240 m^3

Step-by-step explanation:

The volume of a triangular prism is

V = Bh  where B is the area of the base and h is the height

B = the area of the triangular base

B = 1/2 bh

B = 1/2 *5*12

B = 30 m^2

The volume is

V = 30 * 8

V = 240 m^3

Step-by-step explanation:

Answer:

Method 1 (using the area of a whole circle and dividing by 4)

First work out the area of the whole circle by substituting the radius of 8cm into the formula for the area of the circle:

A = π ×r²

= π ×8²

= 64π (leave the answer as an exact solution as this need to be divided by 4).

So all you need to do now is divide the answer by 4:

Area of a quadrant = 64π ÷4 = 16π = 50.3 cm² to 3 significant figures.

Method 2 (using ¼ πr²)

Substitute r = 8 directly into the formula A = ¼ πr².

A = ¼ πr².

A = ¼ × π × 8².

A = 50.3 cm²

As you can see it gives exactly the same answer as method 1.

Answer:

64pi / 4 = 16pi, or 50.27

Step-by-step explanation:

We use the area formula:

π * r^2 = Area

Substitute in 8 for r to get 64pi

Then all you have to do is divide 64pi by 4 to find a quarter of the area of the circle, which is 16pi. Or if you want rounded to nearest tenth, 50.27

Answer:

Answer:

-5 = p

Step-by-step explanation:

-7 - p= p +3

Add p to each side

-7 - p+p= p+p +3

-7 = 2p+3

Subtract 3 from each side

-7-3 = 2p+3-3

-10 = 2p

Divide each side by 2

-10/2 = 2p/2

-5 = p

Answer:

if t is 2 then coefficient will be 3

if t is 3 then coefficient will be 2

Step-by-step explanation:

18 + ?t = 24

subtracting 18 from sides

18 + ?t - 18= 24 -18 = 6

=> ?t = 6 = 2*3

as value of both ? and t is not given thus both can take value of 2 and 3

hence,

if t is 2 then coefficient will be 3

if t is 3 then coefficient will be 2

Answer:

[tex] X = 70.5 [/tex]

Step-by-step explanation:

The law of Cosine given can be written in another form to make the Cos(C) the subject of the formula. Which is: [tex] cos(C) = \frac{a^2 + b^2 - c^2}{2ab} [/tex]

Where,

a = 20 ft

b = 18 ft

c = 22 ft

C = X

[tex] cos(X) = \frac{20^2 + 18^2 - 22^2}{2*20*18} [/tex]

[tex] cos(X) = \frac{400 + 324 - 484}{720} [/tex]

[tex] cos(X) = \frac{240}{720} [/tex]

[tex] cos(X) = 0.3333 [/tex]

[tex] X = cos{-1}(0.3333) [/tex]

[tex] X = 70.5 [/tex]

Answer:

Amount per kilogram, undercharged or overcharged is 0.50

Step-by-step explanation:

Given:

cost of T-bone steaks per pound = $ 15.99

weight listed on package = 5.77 lb

Accuracy of the scale = 1/32 lb

To find:

Amount undercharged or overcharged

Solution:

Let x represent the weight of the package.

Then compute the error in the weight

| x - 5.77 | < 1 / 32

This makes an absolute value inequality

If an inequality is given in the form | x | < a then solution is in the form:

–a < x < a.

If an inequality is in the form | x | > a, then solution splits in the form:

x < –a or x > a.

compute the amount undercharged or overcharged:

First multiply the above inequality by cost of T-bone steaks per pound

15.99 |x - 5.77| < 15.99 (1 / 32)

15.99 |x - 5.77| < 15.99(0.03125)

15.99 |x - 5.77| < 0.4996875

15.99 |x - 5.77| < 0.50

Hence the amount undercharged or overcharged is $0.50

Answer:

[tex]x = -4, y =-8[/tex] is the solution to the system of equations.

Step-by-step explanation:

Given the system of equations as:

[tex]y= \dfrac{1}{2}x-6[/tex]

and

[tex]x =-4[/tex]

To find:

The solution to the system of equations = ?

Solution:

Here, we are given two equations and two variables i.e. [tex]x[/tex] and [tex]y[/tex].

So, we can solve the system of equations for the values of [tex]x[/tex] and [tex]y[/tex].

Let us first consider the 2nd equation.

[tex]x =-4[/tex] we already have the value of [tex]x[/tex].

Now, let us put the value of [tex]x[/tex] in the 1st equation to find the value of [tex]y[/tex].

[tex]y= \dfrac{1}{2}x-6[/tex]

[tex]\Rightarrow y= \dfrac{1}{2}\times (-4)-6\\\Rightarrow y= -\dfrac{1}{2}\times 4-6\\\Rightarrow y= -2-6\\\Rightarrow \bold{y =-8}[/tex]

So,  the solution to the system of equations is:

[tex]x = -4, y =-8[/tex]

Answer:

Step-by-step explanation:

m∠1+∠2=180

2x+40+2y+40=180

2x+2y=180-80

2x+2y=100

x+y=50

x=50-y

m∠1=m∠3

2x+40=x+2y

2x-x=2y-40

x=2y-40

2y-40=50-y

2y+y=50+40

3y=90

y=30

x=50-y=50-30=20

m∠1=2x+40=2×20+40=80°

m∠2=2y+40=2×30+40=60+40=100°

m∠3=x+2y=20+2×30=80°

====================================================

Explanation:

The GCF of the coefficients {6, -42, 14} is 2 as it is the largest factor found in each of the three values.

----------

For the variable portions, we can

Each time we see z^3 show up, so this is the largest common factor among the three variable terms.

----------

The two results we got were 2 and z^3

Putting the two results together, we end up with the overall GCF of 2z^3
