Someone help plz and plz put an answer plz

Answer:

5x2=10 centimeter

Step-by-step explanation:

Answer:

area of a square= length ²

area of a rectangle=length*breadth

area of parallelogram=base *height

Answer:Cube  

Step-by-step explanation:

possibly a cube

Step-by-step explanation:

L+W+L+W=26 so 2L=26–2W and you can find length from the perimeter as L=13−W

LW=42 so L=42/W is the other way to find the length, from the area. Both ways require you to know W, but if you have both pieces of information the two answers for length must be the same 42/W=13−W, and you solve this:

42=13W−W2

W2–13W+42=0

(W−6)(W−7)=0

Either W−6=0 or  W−7=0

Answer:

Step-by-step explanation:

V=4 /3πr^3=4/3·π·48^3≈463246.7

Answer:

(2a,2b)

(-4a,b)

Step-by-step explanation:

for the first one

the x value of coordinate L is going to be twice the value of the x coordinate of k (a)

That being said the x value of L = 2a

The y value of L is going to be half the value of the y value of coordinate A ( 4b )

4b/2=2b so the y value of coordinate L is 2b

now we put the values as an ordered pair

The answer would be (2a,2b)

Answer:

-2

Step-by-step explanation:

since the base are the same you add the exponent.

4x+2 + 2x-1= -3x-17

4x+2x +3x =-17-2+1

9x =-18

x=-2

Answer:

1/20

Step-by-step explanation:

Simple probability is found by counting all the results which fit requirements and dividing by all possible results.

To find probability of two results in a row, multiply chance of first result by chance of second result.

Since you are replacing the marble before the second draw, we don’t have to figure out the various changes in odds for the different possible first draws. It’s just that simple.

There are 5 black marbles

There are 4 red marbles

There are always 20 marbles in all

5/20*4/20=1/4*1/5=1/20

By coincidence, the same as the chance of drawing the white marble in one draw.

Answer:

4.

Step-by-step explanation:

28 = 2*2*7

48 = 2*2*2*2*3

72= 2*2*2*3*3

So the HCF = 2*2 = 4.

Answer:

hcf stand's for

highest common factor

and must be prime numbers

so the answers 3

Answer:

m=1 or m=-3

Step-by-step explanation:

My bad if its wrong hope this helps tho

Given:

The given function is:

[tex]y=-32x^2+90x+3[/tex]

To find:

The range of the given function.

Solution:

We have,

[tex]y=-32x^2+90x+3[/tex]

It is a quadratic function because the highest power of the variable x is 2.

Here, the leading coefficient is -32 which is negative. So, the graph of the given function is a downward parabola.

If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then the vertex of the quadratic function is:

[tex]Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)[/tex]

In the given function, [tex]a=-32,b=90,c=3[/tex].

[tex]\dfrac{-b}{2a}=\dfrac{-90}{2(-32)}[/tex]

[tex]\dfrac{-b}{2a}=\dfrac{-90}{-64}[/tex]

[tex]\dfrac{-b}{2a}=\dfrac{45}{32}[/tex]

The value of the given function at [tex]x=\dfrac{45}{32}[/tex] is:

[tex]y=-32(\dfrac{45}{32})^2+90(\dfrac{45}{32})+3[/tex]

[tex]y=\dfrac{2121}{32}[/tex]

The vertex of the given downward parabola is [tex]\left(\dfrac{45}{32},\dfrac{2121}{32}\right)[/tex]. It means the maximum value of the function is [tex]y=\dfrac{2121}{32}[/tex]. So,

[tex]Range=\left\{y|y\leq \dfrac{2121}{32}\right\}[/tex]

[tex]Range=\left(-\infty, \dfrac{2121}{32}\right ][/tex]

Therefore, the range of the given function is [tex]\left (-\infty, \dfrac{2121}{32}\right ][/tex].

Answer:

373248 cm³ of wax

Step-by-step explanation:

If the crayon is 90 millimeters long, how many cubic centimeters of wax is used to make a box of 8 crayons?

1 crayon = 90mm

8 crayons = x

Cross Multiply

x = 8 × 90mm

x = 720mm

Converting to cubic mm

= (720mm)³ = 373248000mm³

Converting to cubic centimeter

1 mm³ = 0.001 cm³

373248000 mm³ = x

Cross Multiply

373248000 × 0.001 cm³

= 373248 cm³ of wax

Answer:

mike did i think im super sooooo sorry if im wrong

Step-by-step explanation:

Answer:

[tex]x + 4[/tex]

Step-by-step explanation:

The question have missing details.

Because, the question says she collected some cans "after picnic"; This means that she has some cans "before picnic"

So, we assume that she has x bags of can before the picnic.

[tex]After\ Picnic = 4[/tex]

So, the total number of bags collected is:

[tex]Total = Before + After\ Picnic[/tex]

[tex]Total = x + 4[/tex]

If x is 5, then she took 9 bags of can to the recycling center

If x is 2, then she took 6 bags of can to the recycling center

If x is 0, then she took 4 bags of can to the recycling center

Answer:

The volume of the prism is other; 5.04 m^3

Step-by-step explanation:

Here, we want to get the volume of the prism

What we have to do here is to calculate the area of the trapezoid base and multiply by the height of the prism

The area of the base is;

A = 1/2(a + b) h

a and b are the parallel sides of the trapezoid which is 80 cm and 2 m

h is the height of the trapezoid which is 1.2 m

80 cm is same as 80/100 = 0.8 m (100 cm = 1 m)

A = 1/2( 0.8 + 2)1.2

A = 1/2 * 2.8 * 1.2 = 1.68 m^2

So we proceed to multiply this with the height of the prism which is 3 m

This will be ;

1.68 m^2 * 3 m = 5.04 m^3

Answer:

X = 45

Step-by-step explanation:

a^2 + b^2 = c^2

60^2 + a^2 = 75^2

3,600 + a^2 = 5,625

- 3,600            - 3,600

____________________

    a^2= 2025

square root them

a^2 = a

2025 = 45

so x =45

Answer: 100

Step-by-step explanation:

The formula for the area of a trapezoid is (B1+B2)/2*h

so substitute:

(8+12)/2*10

20/2*10

10*10

100

Answer:

100 sq inches

Step-by-step explanation:

Simply use the formula for finding the area:

[tex]\frac{1}{2} * (sum of parallel sides) * height\\= \frac{1}{2} * (8 + 12) * 10\\= \frac{1}{2} * 20 * 10\\= 100 sq. inches[/tex]

Answer:

y = 2x + 24

Step-by-step explanation:

Slope-intercept form equation => y = mx + b

m = slope = change in y / change in x

b = y-intercept

✔️using two pairs of values form the table, (-6, 12) and (-5, 14):

Slope (m) = (14 - 12)/(-5 -(-6))

m = 2/1

m = 2

✔️To find b, substitute (x, y) = (-6, 12) and m = 2 into y = mx + b.

12 = 2(-6) + b

12 = -12 + b

12 + 12 = b

24 = b

b = 24

✔️To write the equation, substitute m = 2 and b = 24 into y = mx + b:

y = 2x + 24

Answer:

C

Step-by-step explanation:

the answer is C because √8 can be rewrite as 8^1/2

A is wrong because 8 is another number

B is wrong because 4 is not the square root of 8

D is wrong because 8^2 = 64

Answer:

Length of the radii of the circles → 4 units and 1 unit

Equation of common tangent → x = 4

Step-by-step explanation:

From the figure attached,

Length of radii of each circles are,

Radius of circle S = 4 units

Radius of circle T = 1 unit

Common point where the circles are touching → (4, 1)

Common tangent to these circles is a line perpendicular to x-axis passing through x = 4,

Equation of the tangent will be,

x = 4
