Using the diameter concept, we have that the correct option is given by:

The ball will fit, because its diameter is approximately 1 cm shorter than the side of the box.

The diameter of a circular or spherical object is the largest distance that can be formed between two parallel lines to it's boundary, hence, basically, the lateral distance occupied by the object.

For this problem, the diameter is in inches, while the available box is in cm, hence we have to convert the diameter to cm.

Each inch has 2.54 centimeters, hence the diameter of ball is of 9.55 x 2.54 = 24 (approximately) < 25, hence it will fit and the correct option is given by:

The ball will fit, because its diameter is approximately 1 cm shorter than the side of the box.

The number of cups of milk when represented as fraction is expressed as 1/2 cup.

Given a recipe indicates 0.5 cup of milk.

A numerical value that designates a portion of a whole is used to represent fractions.A fraction is a part or portion that is taken from the total, which might be any number, a specific sum, or an item.

To convert it into fraction, we first need to remove the decimal.

5/10

when 5 is divided by 10 we get 0.5, hence we have removed the decimal and converted it into its orignal form.

Now multiply and divide by 5.

= 5 × 5/10 × 5

= 1/2

we get the fraction part as 1/2

Hence 0.5 cup of milk represent 1/2 cup of milk as a fraction.

Answer:

-16=0.2b

-16/0.2=b

b= -80 answer

Answer:

In the equation "-16 = 0.2b", b is equal to -80.

Step-by-step explanation:

-16 = 0.2b

Turn the decimal into a fraction. This will make solving simpler.

-16 = [tex]\frac{1}{5}b[/tex]

Multiply both sides by 5.

-80 = 1b

The measure of the angle 8 is option (d). 106.

Measure of Angle

Angle measurement is the amount of rotation from the initial to an endpoint of a ray.

Given,

Measure of Angle 2 = 8x + 10

Measure of angle 6 = x² - 38

Here we need to find the measure of angle 8.

Let us consider the angle 2 and 6 are corresponding angles.

Then,

Measure of Angle 2 = Measure of Angle 6

Apply the corresponding values,

Then we get,

8x + 10 = x² - 38

It can be written as,

=> x² - 38 - 8x - 10 = 0

=> x² - 8x - 48 = 0

When we factorize the equation,

Then we get,

=> (x + 4) ( x - 12) = 0

Then the value of x will be x = -4 and 12.

Here the value of x can't be negative.

So,

=> x = 12

Now apply the value of x on the measure of angle 2,

=> 8(12) + 10

=> 96 + 10

=> 106

So, the measure of angle 8 is option (d). 106.

We get the dimensions of the park as length = 75 feet and width = 20 feet.

We are given that:

A yard has a perimeter of 190 feet.

Also, four times the length of the yard equals 15 times the width.

Now,

Let the length of the yard be x.

ATQ, we get the width of the yard as:

15 width = 4 x

Width = 4 / 15 x

Perimeter = 2 ( l + b )

190 = 2( x + 4 / 15 x )

95 = 19 x / 15

19 x = 95 × 15

19 x = 1425

x = 1425 / 19

x = 75 feet.

A differential equation with some initial conditions is used to solve an initial value problem.

The required particular solution is given by the relation:

[tex]$4y^{(3/2)} = 9e^{(-2x/3)} + 23[/tex]

An initial value problem in multivariable calculus is an ordinary differential equation with an initial condition that specifies the value of the unknown function at a given point in the domain. In physics or other sciences, modeling a system frequently entails solving an initial value problem.

Let the given equation be [tex]$y^{1/2} dy\ dx y^{3/2} = 1[/tex], y(0) = 9

[tex]$(\sqrt{y } ) y^{\prime}+\sqrt{(y^3\right\left) }=1[/tex] …..(1)

Divide the given equation (1)  by [tex]$\sqrt{ y} $[/tex]  giving

[tex]$y^{\prime}+y=y^{(-1 / 2)} \ldots(2)$[/tex], which is in Bernoulli's form.

Put [tex]$u=y^{(1+1 / 2)}=y^{(3 / 2)}$[/tex]

Then [tex]$(3 / 2) y^{(1 / 2)} \cdot y^{\prime}=u^{\prime}$[/tex].

Multiply (2) by [tex]$\sqrt{ } y$[/tex] and we get

[tex]y^{(1 / 2)} y^{\prime}+y^{(3 / 2)}=1[/tex]

(2/3) [tex]u^{\prime}+u=1$[/tex] or [tex]$u^{\prime}+(3 / 2) y=3 / 2$[/tex],

which is a first order linear equation with an integrating factor

exp[Int{(2/3)dx}] = exp(2x/3) and a general solution is

[tex]u. $e^{(2 x / 3)}=(3 / 2) \ln \[\left[e^{(2 x / 3)} d x\right]+c\right.$[/tex]  or

[tex]\mathrm{y}^{(3 / 2)} \cdot \mathrm{e}^{(2x / 3)}=(9 / 4) \mathrm{e}^{(2x / 3)}+{c}[/tex]

To obtain the particular solution satisfying y(0) = 4,

put x = 0, y = 4, then

8 = (9/4) + c

c = (23/4)

Hence, the required particular solution is given by the relation:

[tex]$4y^{(3/2)} = 9e^{(-2x/3)} + 23[/tex]

8).

Given,

For no. Of shirts = 10, price per shirt = $9

For no. Of shirts = 25, price per shirt = $8.40

.

Linear equation be,

y = mx + b

x 10 25

y 9 8.4

9 = 10m + b  (i)

8.4 = 25m + b (ii)

Now,

(i) 9 = 10 m + b  b = 9 - 10m

(ii)  8.4 = 25m + b 8.4 = 25m + 9 - 10m

8.4 - 9 = 15m m = -0.6/15 = -0.04

m = - 0.04

b = 9 - 10m = 9 - 10(-0.04) = 9+0.4 = 9.4

b = 9.4

Using proportions, the coordinates of point G are given as follows:

(1.8, 1.6).

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The points A and B are given as follows:

A(-3, 4) and B(5,0).

For this problem, we have that the ratio of AG to GB is 3:2, hence:

AG = 3/5AB

G - A = 3/5(B - A).

The x-coordinate of G is found as follows:

x + 3 = 3/5(5 + 3)

x + 3 = 4.8

x = 1.8.

The y-coordinate of G is found as follows:

y - 4 = 3/5(0 - 4)

g(-3) = 27

Step-by-step explanation:

We see that the functions defined are:

f(x) = 2x - 1

AND

g(x) = 2x^2 - 3x

This problem asks to find f(-7) and g(-3). To find this, we have to plug the respective numbers into the respective functions.

f(-7) = 2 (-7) - 1

f(-7) = - 14 - 1

f(-7) = -15

g(-3) = 2(-3^2) - 3(-3)

g(-3) = 2(9) + 9

g(-3) = 18+9

g(-3) = 27

The angles are: ∠1 = 22.5°, ∠2 = 67.5°, ∠3 and ∠4 = 45°, ∠5 = 135° and ∠6 = 67.5°.

The flag is rectangle; hence, each corner will be 90°. Now, sum of ∠1 and ∠2 and sum of ∠3 and ∠4 will be 90°. We are given ∠2 is three times the ∠3. So, forming the equation -

∠2 = 3 ∠3

∠2 = 3 ∠1

∠1 + ∠2 = 90

∠1 + 3 ∠1 = 90

4 ∠1 = 90

∠1 = 22.5°

∠2 = 90 - ∠1

∠2 = 90 - 22.5

∠2 = 67.5°

According to Shannon, ∠3 = ∠4

∠3 + ∠3 = 90

2 ∠3 = 90

∠3 = 45° = ∠4

∠2 and ∠6 are the opposite angles and hence are also equal. Also, according to Shannon, ∠6 = 1/2 ∠5.

67.5 = 1/2 × ∠5

∠5 = 67.5 × 2

∠5 = 135°

Hence, each angle is: ∠1 = 22.5°, ∠2 = 67.5°, ∠3 and ∠4 = 45°, ∠5 = 135° and ∠6 = 67.5°.

The equation of the line in slope-intercept form passing through the points (-4.7 , 2.7) and (1.3 , -7.3) is y = -1.67x - 5.13.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The slope-intercept form of the equation of a line is given by the formula:

y = mx + b

where m is the slope of the line

b is the y- intercept

Given the two points, (-4.7 , 2.7) and (1.3 , -7.3), get the slope of the line using the formula:

m = (y2 - y1)/(x2 - x1)

m = (-7.3 - 2.7)/(1.3 - -4.7)

m = -10/6

m = -5/3

Using the slope-intercept form, plug in the value of the slope and one point to determine the y-intercept, b.

y = mx+ b

2.7 = -5/3(-4.7) + b

b = -77/15

Substitute the value of the slope and y-intercept in the slope-intercept form.

y = -5/3 x -77/15

y = -1.67x - 5.13

Hence, the equation of the line in slope-intercept form is y = -1.67x - 5.13.

a = 44 - b

so, the first equation is

So, number of students is 13.

Cost of one candy = $0.79+7%(tax)

Cost of one candy = $0.79 + (7% of 0.79)

Cost of one candy = $ 0.79 + 0.0553

Cost of one candy = $0.8453

So , total cost that Mrs. Herrera to purchase candy will be

Total cost = Number of student X Cost of one candy
