Answer: A

Step-by-step explanation:

Answer:

The value of n is 1/2.

Step-by-step explanation:

[tex] {25}^{2n + 1} = 625[/tex]

[tex] log_{25}(625) = 2n + 1[/tex]

[tex]2 = 2n + 1[/tex]

[tex]2n = 1[/tex]

[tex]n = \frac{1}{2} [/tex]

The solution for the given equation is n=624/625.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 25²n+1=625.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, 625n+1=625

625n=624

n=624/625

Therefore, the solution for the given equation is n=624/625.

Answer:

y=-4/3x+4/5

Answer:

66 tens

Step-by-step explanation:

Required

Solve 66 hundreds / 10

First, we need to express 66 hundreds as a number.

1 hundred = 100

66 hundreds = 66 * 1 hundred

So:

66 hundreds = 66 * 100

66 hundreds = 6600

66 hundreds / 10 would then be calculated as:

66 hundreds / 10 = 6600/10

66 hundreds / 10 = 660

660 can be represented as:

66 hundreds / 10 = 66 * 10

or

66 hundreds / 10 = 66 tens

Hence, option C answers the question

Answer:

Either the abscissa is positive and the ordinate is negative or the abscissa is positive and the ordinate is negative. So, a point could be either (+,-), which lie in quadrant IV, or it could be of the type (-,+), which lie in quadrant II.

Step-by-step explanation:  There are 3 terms there

Answer:

Step-by-step explanation:

The terms of this given expression are 3x^2, 4y and 1. Thus, there are three terms.

[tex]\huge\text{$k=\boxed{117}$}[/tex]

[tex]\displaystyle\frac{k}{3}-5=34[/tex]

To find the value of [tex]k[/tex], we need to isolate it on one side of the equation. Add [tex]5[/tex] to both sides of the equation, then multiply both sides of the equation by [tex]3[/tex].

[tex]\displaystyle\begin{aligned}\frac{k}{3}-5+5&=34+5\\\frac{k}{3}&=39\\\frac{k}{3}*3&=39*3\\k&=\boxed{117}\end{aligned}[/tex]

Answer:

C = 5.50S + 9L

.............

The equation that relates the cost, Cin dollars with the number of small toy cars, S, and the number of large cars, L is  C = 5.50S + 9L.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A hobby shop sells small and large toy cars. A small toy car is $5.50, and a large toy car is $9.

Let S be the number of a small toy car and L be the number of a large toy car.

The equation can be made:

Total cost:

C = 5.50S + 9L

Thus, the equation that relates the cost, Cin dollars with the number of small toy cars, S, and the number of large cars, L is  C = 5.50S + 9L.

Answer:

m=−16

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4m−5(3m+10)=126

4m+(−5)(3m)+(−5)(10)=126(Distribute)

4m+−15m+−50=126

(4m+−15m)+(−50)=126(Combine Like Terms)

−11m+−50=126

−11m−50=126

Step 2: Add 50 to both sides.

−11m−50+50=126+50

−11m=176

Step 3: Divide both sides by -11.

−11m /−11 = 176 /−11

m=−16

Answer:

f = 22

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

140° is an exterior angle of the triangle, thus

4f + 1 + 51 = 140, that is

4f + 52 = 140 ( subtract 52 from both sides )

4f = 88 ( divide both sides by 4 )

f = 22

5) Arun had Rs 965.27 in the bank. He withdrew Rs 209.98. What amount of money is left in the bank?

Given that:

Arun's capital = Rs 965.27 in bank

and he made a withdrawal of Rs 209.98.

The amount left in bank = Rs 965.27 - Rs 209.98

The amount left in bank = Rs 755.29

6) Sachin's weight was 52.8 kg before he became ill. In the first week, he lost 2.9 kg but in the second week, he gained 0.72kg. What was his total weight at the end of the second week?

Initial weight = 52.8 kg

After he became ill:

During the first week, he lost 2.9 kg

Answer: 49 is a perfect square.

Step-by-step explanation: We say that 49 is a perfect square because it is the product of an integer multiplied by itself, 7×7. If we had a square with an area of 50, this wouldn't be a perfect square because no integer, multiplied by itself, will give a product of 50.

Answer:

a. 360.323 m

b. [tex]95.265^{o}[/tex]

Step-by-step explanation:

Distance covered from A to B = speed x time

                                                 = 110 x 2.8

                                                 = 308 m

Distance covered from B to C = speed x time

                                                  = 110 x 1.7

                                                  = 187 m

The sum of angles at B = [tex]64^{o}[/tex] + [tex]26^{o}[/tex]

                                       = [tex]90^{o}[/tex]

a. The distance of the plane from it starting point to C can be determined by applying the cosine rule.

[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] - 2ac Cos B

Sot hat;

[tex]b^{2}[/tex] = [tex]187^{2}[/tex] + [tex]308^{2}[/tex] - 2(187 x 308) Cos [tex]90^{o}[/tex]

But, Cos [tex]90^{o}[/tex] = 0

So that,

[tex]b^{2}[/tex] = [tex]187^{2}[/tex] + [tex]308^{2}[/tex]

  = 34969 + 94864

  = 129833

b = [tex]\sqrt{129833}[/tex]

  = 360.323

The distance from A to C is 360.323 m.

b. Applying the sine rule;

[tex]\frac{a}{SinA}[/tex] = [tex]\frac{b}{SinB}[/tex]

[tex]\frac{187}{SinA}[/tex] = [tex]\frac{360.323}{Sin90^{o} }[/tex]

[tex]\frac{187}{SinA}[/tex] = [tex]\frac{360.323}{1}[/tex]

Sin A = [tex]\frac{187}{360.323}[/tex]

         = 0.5190

⇒ A = [tex]Sin^{-1}[/tex] 0.5190

       = [tex]31.265^{o}[/tex]

The bearing of the plane from its original location = [tex]64^{o}[/tex] + [tex]31.265^{o}[/tex]

                                                     = [tex]95.265^{o}[/tex]

Using the Sine and Cosine rule on the triangle generated using the information given, the distance and bearing of the plane from its original location are :

Using the Cosine Rule :

b² = 187² + 308² - 2(187)(308)Cos(90°)

b² = 187² + 308² - 0

b² = 129833

b = √129833

b = 360.32 miles

B.)

Using the Sine rule :

a/sinA = b/SinB = c/SinC

187/sinA = 360.32/sin90

187/sinA = 360.32/1

sinA × 360.32 = 187

sinA = 187 / 360.32

sinA = 0.51898

A = Sin¯¹(0.51898)

A = 31.264

Hence, bearing of C from A = (64° + 31.264) = 95.26°
