Answer:

Step-by-step explanation:

Change of Base formula: [tex]log_ax=\frac{log_bx}{log_ba}[/tex]

b can be any number.

This formula is used because a lot of calculators can't calculate a logarithm with a base other than 10, so calculators don't show the bases, it is already assumed as base 10.

[tex]log_725=\frac{log_{10}25}{log_{10}7}[/tex]

Type log(25) / log(7) to get: 1.6542

Answer: Choice 1

3(MC) = SC

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

Explanation:

The three medians intersect at the centroid, which is point M in this case. The intersecting medians subdivide themselves in the ratio 2:1

This means that SM is twice as long as MC. We can say SM = 2MC

Then by the segment addition postulate, we know that:

SC = SM + MC

SC = 2MC + MC

SC = 3MC

3(MC) = SC

So having three copies of MC glued together will form segment SC.

The same idea applies for the other medians also (EK = 3EM and RL = 3ML).

Answer:

17.5(D)

Step-by-step explanation:

So, lets see:

Every 5 minutes, Raul answers 22 questions.

The test has 77 questions.

We must figure out the time it takes to answer all 77 questions.

To do this, lets first divide the total questions by the questions answered per 5 minutes:

77 / 22

=

3.5

I got 3.5 knowing that 3x22 is 66, and half(0.5) of 22 is 11, and 11 plus 66 is 77.

So, the 3.5 is how many times he answrs 22 questions in five minutes.

To make a bit more sense, basically we have to multiply the 5 minutes by the 3.5:

3.5*5

=

17.5

We know that 3 times 5 is 15. Half(0.5) of 5 is 2.5, so 15+2.5 is 17.5.

So the answer is that for the 77 quesitons, it takes 17.5 minutes

Answer:

$12.50 per lawn

Step-by-step explanation:

If you get $25 when mowing two lawns(inferred from the table) you would earn exactly half of that amount for 1 lawn.

25 ÷ 2 = 12.5

This means you are earn $12.50 for one lawn or $12.50 per lawn.

Answer:kind of hard try 3x-x+2=4

Step-by-step explanation:

The dimensions of the region with the largest area is length=90 feet and width=45 feet.

Given that, three of the sides will require fencing and the fourth wall already exists.

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Let the length of a wall be l and the width of a wall be w.

So, l+2w=180

⇒ l=180-2w

Area of a rectangle = Length×width

A(w)= (180-2w)×w

= 180w-2w²

The value of 'w' for which the derivate of the area function is zero will yield the maximum area:

A(w)=180w-2w²

⇒ A'(w)=180-4w

⇒ 180-4w=0

⇒ 4w=180

⇒ w=45 feet

So, l=180-2w =90 feet

Therefore, the dimensions of the region with the largest area is length=90 feet and width=45 feet.

Answer:

a = 2, b = -13 and c = 10

Step-by-step explanation:

The given quadratic equation, 2x^2-5x+4=8x-6, must be rewritten in standard form before a, b and c can be identified.

Combining like terms in 2x^2-5x+4=8x-6, we get:

2x^2 - 13x + 10

Then a = 2, b = -13 and c = 10.

How many more of black than blue were sold

First, calculate the difference in percentage sold

[tex]d = 35\% - 23\%[/tex]

Step-by-step explanation:

From the figure attached,

Two lines 'm' and 'n' are two parallel lines. These lines intersect a horizontal line 'l'.

Since, "Pair of opposite angles formed at the point of intersection are the vertical angles and equal in measure."

Therefore, Opposite angles ∠A ≅ ∠G, ∠B ≅ ∠H, ∠C ≅ ∠E and ∠D ∠F are the vertical angles.

♡ Firstly , Here are some of the questions & their answers which should be known before simplifying the given expression :

Q. Do I have to change the sign of each term of second expression while subtracting ?

Ans : Yep! While subtracting , sign of each term of the second expression changes whereas In addition , sign of each term in the expressions remains unchanged.

Q. What do you mean by Like terms & Unlike terms ?

Ans : Well , Like terms are those which have the same base whereas Unlike terms are those which have the different base [ For eg : In 4x , 2y , 3x & 4y , 4x & 3x are like terms and 2y and 4y are like terms ]. Also Remember : Only coefficients of like terms can be added or subtracted.

The Question / Answer part ends up here. Now , Let's get started for simplifying the given expression :
