Answer:

[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

Think, how many different variations are there? The answer is 16: 4 times 4=16

how many of these variations could be the same? lets check:

7 and 7    1

2 and 2  2

2 options out of 16, so the answer is 2/16 which can be simplified to:

Step-by-step explanation:

First find total the weight of all red footed macaws whic is 525(2)=1050

and then the blue and gold macaws 800(3)= 2400

So add them both together yu get 3450grams or 3.45kg

So it is closer to 3kg because the total weight is under 3.5kg so that means you round down to 3kg. If it was 3.5kg you would round up to 4kg but their combined weight is not more than 3.45kg

Step-by-step explanation:

2nd question :

[tex]350 \div 10 = 35 \\ 35 - 10 = 25[/tex]

Answer:

s = [tex]\frac{3}{10}[/tex] m

Step-by-step explanation:

Given s varies directly with m then the equation relating them is

s = km ← k is the constant of variation

To find k use the condition s = 9 when m = 30 , thus

9 = 30k ( divide both sides by 30 )

k = [tex]\frac{9}{30}[/tex] = [tex]\frac{3}{10}[/tex]

s = [tex]\frac{3}{10}[/tex] m ← equation of variation

Answer:

2 1/4

Step-by-step explanation:

- 5 1/4 - ( - 7 1/2)

Subtracting a negative is like adding

- 5 1/4 + 7 1/2

Get a common denominator of 4

-5 1/4 + 7 2/4

Subtract

7 2/4 - 5 1/4

2 1/4

The right answer is 2 1/4

Hey!!

Given,

Length(l)=8m

Breadth(b)=5m

Volume of a cuboid(V)=200 m^3

Height(h)=?

Now,

Volume of a cuboid=l*b*h

or,200=8*5*h

or,200=40h

or,h=200/40

h=5 meter

The height is 5 meter.

Hope it helps

Good luck on your assignment

Answer:

[tex]height = 5m[/tex]

Step-by-step explanation:

[tex]volume = l \times b \times h \\ 200 = 8 \times 5 \times h \\ 200 = 40h \\ \frac{200}{40} = \frac{40h}{40} \\ h = 5m[/tex]

Answer:

0.52

Step-by-step explanation:

→The formula for the volume of a cone is:

V = π[tex]r^2\frac{h}{3}[/tex]

→The "r," (radius) is half the diameter (1), so it's 0.5:

V = π[tex]0.5^2\frac{2}{3}[/tex]

V = 0.52

Answer: 24

Step-by-step explanation:

Answer:

the answer is function 1 has the larger max. at (4,1)

Step-by-step explanation:

draw function 2 : the vertex  is (1,-2)

the vertex of function 1 is (4,1)

The function 1 has a greater maximum value than function 2, and the ordered pair is (1,4).

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

f(x) = -x2 + 2x - 3

Now,

To find the maximum value of a function, we can use the vertex form of a quadratic equation, which is y=a(x−h)2+k

, where (h,k) is the vertex of the parabola. The maximum value of the function is the y-coordinate of the vertex.

For function 1, we can rewrite it as [tex]$$f(x) = -(x-1)^2 + 4$$[/tex]

by completing the square. This means that the vertex of function 1 is (1,4) and the maximum value is 4.

For function 2, we can rewrite it as

[tex]$$f(x) = -\frac{1}{4}(x+2)^2 - 2$$[/tex]

by completing the square. This means that the vertex of function 2 is (−2,−2) and the maximum value is -2.

Therefore, by the given function answer will be (1,4).

Answer:

65°

Step-by-step explanation:

∠1=115°

∠2=65°

∠3=65°

∠4=115°

∠5=115°

∠6=65°

∠7=115°

∠8=65°

We get this because Line m and l are parallel. Also ∠1+∠2=180° so if ∠1 is 115°, then ∠2 is 180°-115° or 65°.

Answer:

It is the second graph B

Step-by-step explanation:

the first graph has the line graphed correctly except that it has a dashed line instead of a solid line because the equation is greater than and equal to the line should be solid not dashed

The inequality of the graph is the shaded area left side of the line. Then the correct option is B.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given as,

y ≥ 4x – 3

The inequality of the graph is the shaded area left side of the line.

Then the correct option is B.
