Answer:

35!

Step-by-step explanation:

5squared is 25 so you then do 25+10 wich = 35!

Step-by-step explanation:

numbers divisible by 2 end with an even number (2,4,6,8,0)

numbers divisible by 5 end with either 5 or 0

Answer:

A,D, and F

Step-by-step explanation:

Any number that is even is divisible by 2.

A D and F are even numbers. If a number ends in 2,4,6,8, or 0 then it is an even number, so you can just look at the last number and determine weather it is divisible by 2.

11.1554 feet

Step-by-step explanation:

The conversion rate for meters to feet is multiplying the given meters by 3.281 so [tex]3.4*3.281[/tex] (The formula is an approximation.) For the answer I would most likely put down 11.15 feet.

Answer:

8.8 m

Step-by-step explanation:

Area of triangle = 38.28 =  * b * 8.7b = 38.28 * 2 / 8.7b = 8.8 m

Answer:

length of short piece = 14ft

length of long piece = 38ft

Step-by-step explanation:

s: short piece, l: long piece

52 = s + l

s = ((52 - 10)/3)

s = (42/3)

s = 14

l = 2s + 10

l = (2 x 14) + 10

l = 28 + 10

l = 38

52 = s + l

52 = 14 + 38

52 = 52

Step-by-step explanation:

for q3 u have to look the number before the dot and then add 1 to it

as for q 4 the decimal numbers are those number which are after the dot for example if ur number is 4.5 u have only one number after the dot THAT is ur decimal number, by the way even if there is a 0 after the dot it is still counted as decimal number

Answer:

x = -91/10

Step-by-step explanation:

-2(5x + 8) = 14 + 61

-10x -16 = 75

-10x = 91

-10x/-10 = 91/-10

x = -91/10

Answer:

c

Step-by-step explanation:

the number goes to both of the numbers in the equation

Given :

⠀

To Find :

⠀

Solution :

We know that,

[tex]\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\: [/tex]

So,

Let's assume the width of the rectangle as x and the length will be (x + 2).

⠀

Now, Substituting the given values in the formula :

[tex]\qquad \sf \: { \dashrightarrow (x + 2) \times x = 48 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x = 48 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x - 48 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} +8x -6x- 48 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x} (x +8) -6(x+8) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow (x +8) (x - 6) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow x = -8, \: \: x = 6 }[/tex]

⠀

Since, The width can't be negative, so the width will be 6 which is positive.

⠀

[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 6\:ft}}}\: [/tex]

[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 6+2=8 \: ft}}}\: [/tex]

Answer:

Yes and no

Step-by-step explanation:

Prime numbers greater than 2 are always odd because if they were even they would be divisible by 2, becoming composite. Not all composite numbers are even, some may be a multiple of two odd numbers. For example, 21 = 3*7

Answer:

1)Reflection,reflection

2)are congruent because reflections are used

Step-by-step explanation:

You reflect figure K so it's upside down.

Then reflect over the y-axis to make it to figure L

The process of two reflections, one horizontally, then vertically will map the two figures

-Chetan K

Answer:

To prove V is a subspace of R, you must show:

(1) It is not empty

(2) Adding vectors returns real numbers

(3) Multiplying by scalars return real numbers

2 & 3 follow the conditions that x,y must be real.

===

(1):

0 = 0 + 0 , therefor V cannot be an empty set. Really thats it.

===

(2)

Let u=(u1, u2 , 2u1-3u2)

Let v *lowercase =(v1, v2, 2v1-3v2)

Great, now lets add them. This isn't intuitive unless you finish reading it all.

u+v = ( u1 + v1 , u2 + v2 , 2u1 - 3u2 + 2v1 - 3u2 )

--> u + v = [ (u1+v1), (u2+v2) , (2u1 + 2v1) + (-3u2 - 3v2) ] (got like terms kinda)

====> All must equal (x,y, 2x-3y)

... which means x=u1+v1 & y=u2+v2 (you compare u+v to V for this)

===

(3)

Let c be a real number.

C(u) = (Cu1, Cu2, C2u1 - C3u2)

====> Must equal (x,y, 2x-3y)

... which means Cu1 = x & Cu2 = y

Cu is in V (because x,y are)

-> V is a subspace of R3.

Answer:

16 i think hehe is it?.....

Answer:

16

Step-by-step explanation:

let ? be x then

11+20+x-2=45

29+x = 45

x = 45-29

x = 16

Graphs are used to represent functions and equations

The best value of x is x = 5

From the question, we understand that x represents the unit of calculating the resale in plot million of rands

This means that x cannot be negative.

So, we have x = 2 and x = 5

The graph is not given.

So, we can assume that the graph is a linear function with a positive slope

For a linear function with a positive slope, the higher the x value, the higher the output value

Hence, the best value of x is x = 5

d. 78

Answer:

B

Step-by-step explanation:

The volume of the cube is the total amount of cubes in the box.

Because the box is a cube, and you know the formula for volume of cube is  L³

L³=125

∛L³=∛125

L=5

there would be 25 cubes in each layer, not 125. Because one layer is L²

Step-by-step explanation:

1. To DECOMPOSE is to break apart a number.

e.g. to decompose 853:  800 + 50 + 3

2. The NUMERATOR is the top number in a fraction (the bottom number is the denominator).

3. A number that has whole number part and fraction part is a MIXED NUMBER, e.g. [tex]6\frac23[/tex]
