Answer:

x = 12.5

Step-by-step explanation:

x2 = 25 Divide both sides by 2

x = 12.5

Answer:

\(\huge\boxed{x = \± \ 5}\)

Step-by-step explanation:

\(\sf x^2 = 25\)

Taking sqrt on both sides

\(\sf \sqrt{x^2} = \sqrt{25}\)

x = ± 5

1. Subtract 13 to both sides of the equation:

2. Divide the resulting equation by 5 to both sides of the equation:

Therefore, the value that solves this equation is W = 21/5 or W = 4.2 (using a decimal expression.)

Answer: To find the area of the rectangle, we need to multiply its length by its width.

The length of the rectangle is 4 and 2/4 meters, which is equivalent to 4.5 meters (since 2/4 can be simplified to 1/2, and 4 + 1/2 = 4.5).

The width of the rectangle is 7 and 5/6 meters, which is equivalent to 7.83 meters (since 5/6 can be simplified to 0.83, and 7 + 0.83 = 7.83).

Therefore, the area of the rectangle is:

Area = length x width

Area = 4.5 meters x 7.83 meters

Area = 35.2935 square meters (rounded to four decimal places)

So, the area of the rectangle is approximately 35.2935 square meters, which can be simplified to 35 and 6/24 square meters or 35 and 1/4 square meters.

Therefore, the answer is: Thirty-five and one-fourth (35 1/4) square meters.

Answer:

\(\dfrac{1}{3}(b-21)\)

Step-by-step explanation:

We need to find an equivalent expression for \(\dfrac{1}{3}b-7\)

The denominator of first fraction is 3 and that of other is 1.

\(\dfrac{1}{3}b-7\\\\=\dfrac{b-21}{3}\)

or

\(=\dfrac{1}{3}(b-21)\)

Hence, the equivalent expression is \(\dfrac{1}{3}(b-21)\).

The answer Is 1/3(b-21)

The coordinates of the vertices after a dilation of the scale factor would be:

To perform a dilation with a scale factor of 1/2 centered at the origin, we multiply the coordinates of each vertex by the scale factor.

Given the vertices:

W = (5, 10)

V = (0, -10)

U = (5, -10)

After applying the dilation with a scale factor of 1/2, the new coordinates of the vertices would be:

W' = (5 * 1/2, 10 x 1/2) = (2.5, 5)

V' = (0 * 1/2, -10 x 1/2) = (0, -5)

U' = (5 * 1/2, -10 x 1/2) = (2.5, -5)

Answer:

10,800

Step-by-step explanation:

75% of all purchases are 15$ and 25% of them are 9$ so if you get 75% of 800, 600, and 25% of it , 200, and multiply 600 by 15 and 200 by 9 you would get 9000 and 1800. and then add them you would get 1800.

i think

Answer:

f(3) would be 9 in this case.

Step-by-step explanation:

To find the value f(3) if f(h) = 4h - 3, substitute h for 3.

f(3) = 4(3) - 3

Multiply 4 by 3 to get 12.

f(3) = 12 - 3

Subtract 3 from 12 to get 9.

f(3) = 9

f(3) would be 9 in this case.

The value of x in this problem, considering the intersecting chords, is given as follows:

x = 10.

A chord of a circle is a straight line segment that connects two points on the circle, that is, it is a line segment whose endpoints are on the circumference of a circle.

When two chords intersect each other, then the products of the measures of the segments of the chords are equal.

Hence the value of x is obtained as follows:

12x = 15 x 8

12x = 120

x = 10.

\(y = 3x +1\)

Step-by-step explanation:

Given

\(m = 3\)

\((x_1,y_1) = (-2,-5)\)

Required

The equation

This is calculated as:

\(y = m(x - x_1) + y_1\)

So, we have:

\(y = 3(x - -2) -5\)

\(y = 3(x +2) -5\)

Open bracket

\(y = 3x +6 -5\)

\(y = 3x +1\)

Answer:

(2a^3a^4)^5 simplifies to 32a^35.

Step-by-step explanation:

To simplify (2a^3a^4)^5, we can use the properties of exponents which states that when we raise a power to another power, we can multiply the exponents. Therefore, we can rewrite the expression as:

(2a^3a^4)^5 = 2^5 * (a^3a^4)^5

Next, we can simplify the expression inside the parentheses by multiplying the exponents:

a^3a^4 = a^(3+4) = a^7

Substituting this into our expression, we get:

(2a^3a^4)^5 = 2^5 * (a^3a^4)^5 = 2^5 * a^35

Finally, we can simplify this expression by using the property of exponents that states that when we multiply two powers with the same base, we can add their exponents. Therefore, we can rewrite the expression as:

2^5 * a^35 = 32a^35

Therefore, (2a^3a^4)^5 simplifies to 32a^35.

The number of words Gillan can read in 1 minute is,  165

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

Gillan read 3,135 words in 19 minutes

The number of words read each minute = w

Now, it has given,

Total words = 3135

Time taken = 19 minutes

For words per minute,

we need to take ratio of total words and total time taken,

Ratio =  Total words/Time taken

         =   3135/19

         =   165

Hence, the number of words in 1 minute is 165

Answer:

g = 3

Step-by-step explanation:

13=3g-2(-5+g)

3g-2(-5+g)  = 13     {Use distributive rule}

3g - 5*(-2) + g(-2) = 13

3g + 10 -2g  = 13           {Combine like terms}

3g - 2g + 10 = 13

         g + 10 = 13          {subtract 10 from both sides}

                g = 13 - 10

g = 3

The surface areas for each figures are:

1. The surface area of the cuboid is:

Top and bottom: 2(10 ft x 4 ft) = 80 ft²

Front and back: 2(10 ft x 5 ft) = 100 ft²

Sides: 2(4 ft x 5 ft) = 40 ft²

Total surface area = 80 + 100 + 40 = 220 ft²

2. The surface area of the cuboid is:

Top and bottom: 2(18 cm x 5 cm) = 180 cm²

Front and back: 2(18 cm x 5 cm) = 180 cm²

Sides: 2(5 cm x 5 cm) = 50 cm²

Total surface area = 180 + 180 + 50 = 410 cm²

3. The surface area of the prism is:

Top and bottom: 2(5 cm x 14 cm) = 140 cm²

Front and back: 2(5 cm x 12 cm) = 120 cm²

Sides: 2(12 cm x 14 cm) = 336 cm²

Total surface area = 140 + 120 + 336 = 596 cm²

4. The surface area of the stacked cuboids is:

Top and bottom of first cuboid: 2(6 cm x 7 cm) = 84 cm²

Front and back of first cuboid: 2(6 cm x 2 cm) = 12 cm²

Sides of first cuboid: 2(7 cm x 2 cm) = 28 cm²

Front and back of second cuboid: 2(7 cm x 2 cm) = 28 cm²

Sides of second cuboid: 2(2 cm x 4 cm) = 8 cm²

Front and back of third cuboid: 2(2 cm x 10 cm) = 40 cm²

Sides of third cuboid: 2(10 cm x 8 cm) = 160 cm²

Total surface area = 84 + 12 + 28 + 28 + 8 + 40 + 160 = 360 cm²

5. The surface area of the cylinder is:

Top and bottom: 2π(6 mm)² = 72π mm²

Side: 2π(6 mm)(5 mm) = 60π mm²

Total surface area = 72π + 60π = 132π mm²

6. The surface area of the cylinder is:

Top and bottom: 2π(1 ft)² = 2π ft²

Side: 2π(1 ft)(10 ft) = 20π ft²

Total surface area = 2π + 20π = 22π ft²

7. The surface area of the cylinder stacked on a cube is:

Top and bottom of cylinder: 2π(5 m)² = 50π m²

Side of cylinder: 2π(5 m)(8 m) = 80π m²

Surface area of cube: 6(10 m x 13 m) = 780 m²

Total surface area = 50π + 80π + 780 = (130π + 780) m²

8. The surface area of the cylinder is:

Top and bottom: 2π(9 in)² = 162π in²

Side: 2π(9 in)(4 in) = 72π in²

Therefore, the total surface area of the cylinder is:

Answer: n=110, m=110

Step-by-step explanation: I think m=110 because of vertical angles. m might also equal 70.

The points that will lie on the line will be (0, 0) , (1, - 25) , (- 1, 25).

The general equation of a straight line is : y = mx + c.

[m] is called slope and it tells the unit rate of change in [y] with respect to [x].

[c] is called the [y] - intercept.

We have some points that lie on a line that passes through the origin with a slope of −25.

The equation of a straight line that passes through the origin and has slope of -25 will be -

y = - 25x

The points that will lie on the line will be -

(0, 0) , (1, - 25) , (- 1, 25)

Therefore, the points that will lie on the line will be (0, 0) , (1, - 25) , (- 1, 25).
