Number of rows = number of columns = r

:: r × r = 1296

In other words,

r square 2 = 1296

now solve in prime factorization,

the answer is 36

Answer:

[tex]5^{1/6} =2x[/tex]

Step-by-step explanation:

Log and exponential forms are inverses. Additionally, the information from one can be used to write in it another form. In a log equation, there are three parts. The formula is [tex]log_{b}(x)=y[/tex]. The formula for exponential equations is [tex]b^y=x[/tex]. This means to find this equation in exponential form write 5 as the base, 1/6 as the power, and 2x as the other side of the equation. This looks like, [tex]5^{1/6} =2x[/tex].

Answer: 16.25 or 16 1/4 miles a week

Step-by-step explanation:

Since the route is 3.25 miles long, and chloe and corinne ride the route 5 times a week, we can use the equation 3.25 x 5 to get to our solution.

3.25 x 5 = 16.25

Answer:

1/2/11

Step-by-step explanation:

1/5×5/10/11=1/5×65/11

=13/11

=1/2/11

The percentage error in the deer population is 17%

Actual population = 21300

Estimated population = 17600

The percentage error will be calculated by subtracting the estimated population from the actual population and then dividing the result. This will be:

= (Actual population - Estimated population) / Actual population × 100

= (21300 - 17600) / 21300 × 100

= 3700/21300 × 100

= 0.17 × 100

= 17%

Therefore, the percentage error in the deer population is 17%

Step-by-step explanation:

16/54 as a percentage is 29.6296%. round up to get the nearest whole number.

29.6296 rounded up is 30

Answer:

16 = 30% of 54

Step-by-step explanation:

16/54 =x/100

(16/54)(100%) = x

(0.296)(100%) = x

29.6% = x

30% = x

Answer:

1.5 pounds more.

Step-by-step explanation:

3.75 - 2.25

= 1.50.

Answer:

1.50 pounds

Step-by-step explanation:

Paula orders a macaroni salad and coleslaw each weighing 3.75 and 2.25 pounds respectively

so, to find how many more pounds of macaroni salad than coleslaw we do,

3.75-2.25=1.50

therefore,  macaroni salad has 1.50 pounds more than coleslaw.

The correct reason for each step in the solution of the equation would be as follows:

12 − 5x + 6x = 4 - Given

12 + x = 4 - Combine Like Terms

x= −8 - Subtraction Property of Equality

Answer:

ΔAOK ≅ ΔBOL by SAS

Step-by-step explanation:

Hello there!

We are given:

Line segment AB intersects line segment KL at point O

O is the midpoint of AB

O is the midpoint of L

We want to prove that ΔAOK is congruent to ΔBOL

From the given picture, line segments AK and LB don't exist, but we can draw them in

Once we've drawn them in, we can use the given information to help us

Since O is the midpoint of AB, AO = OB by the definition of a midpoint

O is also the midpoint of LK, and because of that, LO=OK, also because of the definition of a midpoint

Since O is the intersection of AB and KL, that means that O would help form the vertical angles <LOB and <KOA (which are congruent because of vertical angles theorem)

Now, we have 2 sides and an angle which are congruent.

In the answer, we already have ΔAOK filled in

Remember that when naming congruent triangles, the congruent pieces need to match

A corresponds with B

O corresponds with O

K corresponds with L

So, that means ΔAOK ≅ ΔBOL

The reason is because of SAS (side-angle-side). The reason why it's SAS is because we have 2 pairs of congruent sides and one angle which is congruent

Answer:

0.25

Step-by-step explanation:

Half of a tenth in 5 hundredths.

To find the midpoint of 0.2 and 0.3, think of it as 20 and 30.

What would be the midpoint of 20 and 30? 25.

Therefore, 0.25 would be the midpoint of 0.2 and 0.3

Answer:

Midpoint = (1,2)

Step-by-step explanation:

Using coordinates: D(-2,3) and L(4,1)

Using the midpoint formula:

Midpoint of DL = (D1 + L1) / 2, (D2 + L2) / 2

Midpoint of DL = (-2 + 4) / 2, (3 + 1) / 2

Midpoint of DL = (2) / 2, (4) / 2

Therefore the midpoint of DL is (1,2)

deu ruim  aqui pq eu não sei

Step-by-step explanation:

The question is an illustration of related rates.

The rate of change between you and the ball is 0.01 rad per second

I added an attachment to illustrate the given parameters.

The representations on the attachment are:

[tex]\mathbf{x = 100\ m}[/tex]

[tex]\mathbf{\frac{dy}{dt} = 2\ ms^{-1}}[/tex] ---- the rate

[tex]\mathbf{\theta = \frac{\pi}{4}}[/tex]

First, we calculate the vertical distance (y) using tangent ratio

[tex]\mathbf{\tan(\theta) = \frac{y}{x}}[/tex]

Substitute 100 for x

[tex]\mathbf{y = 100\tan(\theta) }[/tex]

[tex]\mathbf{\tan(\theta) = \frac{y}{100}}[/tex]

Differentiate both sides with respect to time (t)

[tex]\mathbf{ \sec^2(\theta) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot \frac{dy}{dt}}[/tex]

Substitute values for the rates and [tex]\mathbf{\theta }[/tex]

[tex]\mathbf{ \sec^2(\pi/4) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]

This gives

[tex]\mathbf{ (\sqrt 2)^2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]

[tex]\mathbf{ 2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]

Divide both sides by 2

[tex]\mathbf{ \frac{d\theta}{dt} = \frac{1}{100} }[/tex]

[tex]\mathbf{ \frac{d\theta}{dt} = 0.01 }[/tex]

Hence, the rate of change between you and the ball is 0.01 rad per second

Answer:

b = c/3 + 2/3

Step-by-step explanation:

3b - 4/2 = c

the goal is to have b all by itself on one side of the equals sign.

start by moving the fraction over to where c is by adding.

3b = c + 4/2

adding -4/2 and +4/2 together makes it a 0 on the b side so there's no need to write anything in that space anymore.

Now 3b are next to each other which means they are multiplying. To move 3 we need to do the opposite (divide by 3 on both sides of the equal sign)

b = c/3 + 2/3

notice I divided both c and 4/2 by 3. 4/2 = 2 so I changed it to 2, then divided by 3
