Help plz!!!?!?!?!!!!!!!!!!

Step-by-step explanation:

Area = (1/2) *b*h

60 =(1/2)*10h

120 =10h

h=120/10

h= 12 cm

From the figure,

AB=BC(since the given triangle isosceles).

AE is perpendicular to BC.

BE =EC = 5cm ( since is AE bisects BC)

AB= h=12cm (height of the isosceles triangle)

Applying Pythagoras theorem in triangle ABE,

AB² = BE²+ AE²

AB² = 5²+12²

AB² = 169

AB =√169

AB= 13 cm

Hence AB=BC =13cm

Length of equal sides =13cm

Answer:

29 rows of 40

Step-by-step explanation:

1200-35=1165

1165/40=29.125

Answer:

The answer is 19

Step-by-step explanation:

Range is the difference between the largest and smallest number, so in this case the largest number is 25 and the smallest number is 6. Subtract 25 and 6 to get the range. So the answer would be, The range of the following numbers is 19.

Answer:

rational expression

Step-by-step explanation:

From the given information:

Since the quotient of two algebraic expressions seems to be a fractional expression,

Then the quotient of two polynomials;

For example:

[tex]\dfrac{1}{w}, \dfrac{2w-1}{w+1} \ or \ \dfrac{w^2-1}{w^2+1}[/tex]  is a rational expression.

Answer:

5 would be your answer.

Step-by-step explanation:

The answer is 5 because you have to divide 25 by 5, and you will get 5.

If I'm wrong, please let me know.

Hope this helps.

Have a great day! :)

Answer:

5

Step-by-step explanation:

This is right because you would divide 25 by 5 and you would get your answer. You make $5 every hour

Answer: there are 8 cookies left

Step-by-step explanation:

Let's count how many cookies Max baked:

125% = 1.25

64 × 1.25 = 80

Let's count how many cookies were sold:

90% = 0.9

80 × 0.9 = 72

Leftover cookies:

80 - 72 = 8

Answer:

B

Step-by-step explanation:

Answer:

52

Step-by-step explanation:

We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:

[tex]3x + 7 = 163[/tex]

We want to isolate the variable, so subtract 7 from both sides. This gives us:

[tex]3x = 156[/tex]

Finally, we divide both sides by  3, giving:

[tex]x=52[/tex]

So the teacher is 52 years old.

Hope this helps!

Answer: The teacher is 52.

Equation: 7+3t=163

Answer:

y=1/2x-3

Step-by-step explanation:

I hope you meant slope of the line...

You can find the slope like this-

1/2x= how you move (so m for move)

-3 =where you begin (so b for begin)

So next time you find the slope, just ask yourself where you "begin" (where the line starts) and how you "move" (how the line moves)

Answer:

  63.4% are girls

Step-by-step explanation:

The percentage that is boys is ...

  1244/3400 × 100% = 36.6%

The remaining fraction is girls:

  100% -36.6% = 63.4% . . . girls

Answer:

The measure of angle A is: m∠A = 96

Therefore, option A is true.

Step-by-step explanation:

Given

m∠C = 3x

m∠D = x+52

We know that the opposite angles of a parallelogram are also equal.

Determining m∠A

It is clear that A is the opposite angle of C.

i.e.

m∠A = m∠C

as m∠C = 3x

so m∠A = 3x

Determining  m∠B

It is also clear that B is the opposite angle of D.

i.e.

m∠B = m∠D

as m∠D = x+52

so m∠B = x+52

We know that the sum of the angles of a parallelogram is 360°.

so

m∠A + m∠B + m∠C + m∠D = 360°

3x + (x+52) + 3x + (x+52) = 360°

Group like terms

[tex]3x+x+3x+x+52+52=360^{\circ \:}[/tex]

[tex]8x+104=360^{\circ \:}[/tex]

Subtract 104 on both sides

[tex]8x+104-104=360^{\circ \:}-104[/tex]

Simplify

[tex]8x=360^{\circ \:}-104[/tex]

[tex]8x=256[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}=\frac{256}{8}[/tex]

Simplify

[tex]x=32[/tex]

Thus,

The measure of the angle A is:

m∠A = 3x

substitute x = 32

m∠A = 3(32)

m∠A = 96

Hence, the measure of angle A is: m∠A = 96

Therefore, option A is true.

Answer: The exponential function would be

Step-by-step explanation:

Since we have given that

We have points (0,15) and (2,24)

First we take when x= 0, y = 15.

So, our equation becomes,

and we take when x = 2 and y = 240

So, the exponential function would be
