Answer:

3 1/2 ; 3 19/20 ; 3 39/40

Step-by-step explanation:

Find common denominators. Change all mixed fraction to improper fractions before finding common denominators.

3 1/2  = 6/2 + 1/2 = 7/2

3 19/20 = 60/20 + 19/20 = 79/20

3 39/40 = 120/40 + 39/40 = 159/40

Find the common denominators. The smallest common denominators is 40. Remember that what you do to the denominator you do to the numerator:

3 1/2 = (7/2)(20/20) = 140/40

3 19/20 = (79/20)(2/2) = 158/40

3 39/40 = (159/40) = 159/40

Least to Greatest:

3 1/2 ; 3 19/20 ; 3 39/40

Answer:

A: The value of both expressions when w=1 is 28.

D: The two expressions are not equivalent.

Step-by-step explanation:

Given expressions are:

4(3w+4)

and

16w+12

For w=1

First Expression:

4(3w+4)

= 4[3(1)+4]

=4(3+4)

=4(7)

=28

Second expression:

16w+12

= 16(1)+12

=16+12

=28

For w=3

First Expression:

4(3w+4)

= 4[3(3)+4]

=4(9+4)

=4(13)

=52

Second expression:

16w+12

= 16(3)+12

=48+12

=60

Now looking at the statements:

A: The value of both expressions when w=1 is 28.

The statement is true because our calculated values of both expressions are 28 for w=1.

B: The two expressions are equivalent.

The two expressions are not equivalent because their values at w=3 are not same.

C: The value of both expressions when w=1 is 16.

The value of both expression when w=1 is 28 so this statement is not correct

D: The two expressions are not equivalent.

We can see by comparing the values that both expressions are not equivalent.

E: The value of both expressions when w=3 is 52.

F: The value of both expressions when w=3 is 60.

Both statements are false because both expressions have different values at w=3 ..

A. The value of both expressions when w=1 is 28. D. The two expressions are not equivalent. Statements A and D are true.

To determine if the two expressions are equivalent, we need to substitute w=1 and w=3 into both expressions. The first expression is 4(3w+4) and the second expression is 16w+12.

Step-by-step explanation:

Mass = Volume x density

Mass = 8.4 gm

Density = 2.4 g/cc

Substituting

       8.4 = Volume x 2.4

       Volume = 3.5 cm³

[tex]\texttt{Volume of sphere =}\frac{4}{3}\pi r^3[/tex]

We need to find radius, r

Substituting volume value

              [tex]\texttt{Volume of sphere =}\frac{4}{3}\pi r^3=3.5\\\\r^3=0.836\\\\r=0.941cm=1cm[/tex]

Radius of grape = 1 cm  

To solve the problem we must know about volume.

The radius of the sphere is whose mass is 8.2 grams and has a density of 2 grams per cubic centimeter is 1 cm.

The volume can be defined as the space occupied by the three-dimensional object.

It is given by the ratio of mass(m) and density(ρ).

[tex]\text{Volume of the object} = \dfrac{m}{\rho}[/tex]

Given to us

Mass of the object, m = 8.4 grams

Density of the object, ρ = 2 gram/cm³

As it is already mentioned that the volume is equal to the ratio of its mass to density. therefore,

[tex]\text{Volume of the object} = \dfrac{m}{\rho}\\\\\text{Volume of the object} = \dfrac{8.4}{2}\\\\\text{Volume of the object} = 4.2\ cm^3[/tex]

Thus, the volume of the object is 4.2 cm³.

To find the radius of the sphere we will use the formula of the volume of the sphere.

[tex]\text{Volume of sphere} = \dfrac{4}{3}\pi r ^3[/tex]

Substitute the values,

[tex]4.2 = \dfrac{4}{3}\pi r ^3\\\\r = 1\rm\ cm[/tex]

Hence, the radius of the sphere is whose mass is 8.2 grams and has a density of 2 grams per cubic centimeter is 1 cm.

The distance between the points (2, 1) and (-2, 2) is √17, which is approximately 4.123 units.

We have,

The coordinates of point A =(2, 1)  and C = (-2, 2)

Now,

To find the distance between two points, (x₁, y₁) and (x₂, y₂), we can use the distance formula:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Given the points (2, 1) and (-2, 2), we can substitute the values into the formula:

Distance = √[(-2 - 2)² + (2 - 1)²]

Distance = √[(-4)² + 1²]

Distance = √[16 + 1]

Distance = √17

Answer:

34.4°C (rounded up to nearest tenth)

Step-by-step explanation:

Given; F = [tex]\frac{9}{5}[/tex]C + 32

94°F = [tex]\frac{9}{5}[/tex]C + 32

[tex]\frac{9}{5}[/tex]C = 94 - 32 = 62

C = [tex]\frac{62 * 5}{9}[/tex] = 34.44444444°C

And is equal to: 34.4°C (rounded up to nearest tenth)

The Celsius temperature equaling 94 degrees Fahrenheit is 34.44°C.

To find the Celsius temperature equivalent to 94 degrees Fahrenheit using the formula F = (9/5)C + 32:

Substitute 94 for F: 94 = (9/5)C + 32

Then solve for C: C = (94 - 32) / (9/5) = 34.44°C

The Celsius temperature equaling 94 degrees Fahrenheit is 34.44°C.

[tex](x^{\frac{1}{15}})^{5}[/tex]

Simplify

Multiply the exponents

[tex](x^{\frac{1}{15}})^{5}=x^{\frac{1}{15}*5}=x^{\frac{5}{15}}=x^{\frac{1}{3}}=\sqrt[3]{x}[/tex]

Answer:

[tex]\sqrt[3]{x}[/tex].

Step-by-step explanation:

We have been given an expression [tex](x^{\frac{1}{15}})^5[/tex]. We are asked to simplify our given expression.

We will use power rule of exponents [tex](a^b)^c=a^{b\cdot c}[/tex] to simplify our given expression as:

[tex](x^{\frac{1}{15}})^5=x^{\frac{1}{15}\times 5}[/tex]

[tex](x^{\frac{1}{15}})^5=x^{\frac{1}{3}\times 1}[/tex]

[tex](x^{\frac{1}{15}})^5=x^{\frac{1}{3}}[/tex]

Using fractional exponent rule [tex]a^{\frac{1}{n}}=\sqrt[n]{a}[/tex], we can write our expression as:

[tex](x^{\frac{1}{15}})^5=\sqrt[3]{x}[/tex]

Therefore, the simplified form of our given expression would be [tex]\sqrt[3]{x}[/tex].

Given the functions

(a) f(x) = x³ + 5x² + x

(b) f(x) = x² + x

(c) f(x) = -x

Function (a)

f(-x) = (-x)³ + 5(-x)² + (-x)  

      = -x³ + 5x² - x

      = -(x³ - 5x² + x)

The function is neither even nor odd.

Function (b)

f(-x) = (-x)² + (-x)

       = -(-x² + x)

The function is neither even nor odd.

Function (c)

f(-x) = -(-x)  

      = x

      = -f(x)

Because f(-x) = -f(x) the function is odd.

Answer: f(x) = -x is an odd function.

When evaluating the expression [tex]b^2c - 1[/tex] for b = -4 and c = 2, we calculate b squared as 16, multiply by c to get 32, and subtract 1 to obtain the answer 31.

To evaluate the expression b2c - 1 for b = -4 and c = 2, we need to follow the order of operations, often referred to as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, we calculate b², which is (-4)² = 16.

Next, we multiply this result by c, which gives us 16 * 2 = 32.

Finally, we subtract 1 from this product, resulting in 32 - 1 = 31.

Therefore, the evaluated expression [tex]b^2c - 1[/tex] is 31 when b = -4 and c = 2.

$1,475

Step-by-step explanation:

times 100 by 14 which is 1400

but then add 75 onto that

Answer:

$1475

Step-by-step explanation:

One week costs $100.

Note that:

The $75 enrollment fee is a one-time payment.

$100 per week is the amount that is paid per week, and can change depending on the amount of week they pay for.

In this case, the child would be there for 14 weeks. Set the equation. Let x = amount of weeks, and t = total cost:

100x + 75 = t

We know that the child will be there for 14 weeks, so plug in 14 for x.

(100)(14) + 75 = t

t = (100 * 14) + 75

Simplify. Remember to follow PEMDAS. Multiply first, then add:

t = (1400) + 75

t = 1475

The total cost for 14 weeks is $1475.

Step-by-step explanation:

considering APB as the triangle

AP is the tangent to the circle.

∴ OA ⊥ AP  (Radius is perpendicular to the tangent at the point of contact)

⇒ ∠OAP = 90º  

In Δ OAP,

sin ∠OPA = OA/OP = r/2r [Diameter of the circle]

∴ sin ∠OPA = 1/2 = sin 30º

⇒ ∠OPA =  30º

Similarly, it can he prayed that ∠OPB = 30

How, LAB = LOP + LOB = 30° + 30° = 60°  

In APB,  

PA = PB [lengths &tangents drawn from an external point to circle areequal]  

⇒ ∠PAB = ∠PBA --- (1) [Equal sides have equal angles apposite to them]  

∠PAB + ∠PBA + ∠APB = 180° [Angle sum property]  

∠PAB + ∠PBA + ∠APB = 180° - 60° [Using (1)]  

⇒ 2∠PAB = 120°

⇒ ∠PAB = 60°  

From (1) and (2)  

∠PAB = ∠PBA = ∠APB = 60°

APB is an equilateral triangle.

Final answer:

The equation of a circle with center (2,7) and a radius of 5 is (x - 2)² + (y - 7)² = 25.

Explanation:

To find the equation of a circle with its center at (2,7) and a radius of 5, we use the standard form of the equation for a circle which is (x - h)² + (y - k)² = r², where (h,k) is the center of the circle and r is the radius.

Plugging in the given values for our circle we have:

(x - 2)² + (y - 7)² = 5²

Expanding the right side of the equation gives us:

(x - 2)² + (y - 7)² = 25

This is the desired equation of the circle. It represents a circle with a radius of 5, centered at the point (2,7).

Answer:

x = 80, y = 140 and z = 20

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles in the triangle with x and equate to 180

x + 60 + 40 = 180

x + 100 = 180 ( subtract 100 from both sides )

x = 80

40° and y form a straight angle and are supplementary, hence

40 + y = 180 ( subtract 40 from both sides )

y = 140

Sum the 3 angles in the triangle with z and equate to 180

z + y + 20 = 180, that is

z + 140 + 20 = 180

z + 160 = 180 ( subtract 160 from both sides )

z = 20

Answer:

B 65

65= y

The correct equation representing the situation where Nancy's mother added candies to the 16 candies already in the bag is 16 + c = 32. Subtracting 16 from both sides gives the result c = 16, which is the number of candies her mother added.

The subject of this question is mathematics and it belongs to the middle school level. Nancy began with 16 candies and ended up with 32 candies after her mother added some. Nancy wants to find out how many candies her mother added.

To solve this problem, we need to use a simple addition equation. The equation that correctly represents the situation is 16 + c = 32. This equation says that Nancy's original amount of candies (16) plus the candies her mother added (c) equals the new total amount of candies (32).

To solve for c (the number of candies her mother added), we simply subtract 16 from both sides of the equation. Therefore, c = 32 - 16, which leads to c = 16, which is the number of candies her mom put in the bag.

Final answer:

The correct equation for Nancy's chocolate candies is 16 + c = 32, solving for c reveals that 16 candies were added. Jenny initially had 14 chocolates before eating two and giving half of the remainder to Lisa.

Explanation:

The question asks to identify the correct equation to solve for the number of chocolate candies, c, that Nancy's mom put in the bag. Nancy originally had 16 chocolate candies, and her mother added some candies to the bag, increasing the total to 32 candies. The equation that represents this situation is 16 + c = 32. This equation can help Nancy find out how many candies her mother added to the bag.

To solve for c, we need to perform a subtraction operation:

This calculation gives us the number of candies Nancy's mother added, which means c = 16 candies.

Jenny's Chocolate Question

If Jenny has some chocolates, eats two, and gives half of what is left to Lisa, resulting in Lisa having six chocolates, then we must work backward to find the initial amount. Since Lisa received half of the remainder, Jenny must have had 12 chocolates after eating two. This means Jenny started with 14 chocolates as:

The correct answer for Jenny's beginning number of chocolates is 14.

Step-by-step explanation:

8x^2 + 80x = −5

Factor out an 8

8(x^2 + 10x) = −5

Take the coefficient of the x term, divide by 2 and then square it

10/2 = 5, 5^2=25

Remember we have the 8 outside, so we are multiplying by 8

8*25 =200

Add 200 to each side

8(x^2 + 10x + 25) = −5 + 200

Answer:

Missing number is 200.

Step-by-step explanation:

In the completing the square method we follow the following steps,

Step 1 : Move constant term to the right side,

Step 2 : Make 1 as the coefficient of [tex]x^2[/tex]

Step 3 : Add square of the half of the coefficient of x in the left side and balance the equation,

Here, the given equation,

[tex]8x^2+ 80x = -5[/tex]

[tex]8(x^2 + 10x) = -5[/tex]

∵ coefficient of x = 10,

Half of 10 = 5,

Square of 5 = 25,

Thus, we need 25 inside the bracket in left side,

For this, add 200 on both side,

[tex]8(x^2 + 10x+25) = -5+200[/tex]

Hence, missing number in the last step is 200.
