Further explanation

Answer and explanation:

The equation y=19x+350 representing the total cost for the banquet hall based on number of people attending has both dependent and independent variables.

The independent variable is x which represents the number of people attending(each person costs $19) and therefore determines the total cost y which will be the cost of the banquet hall given number of people attending x

If we make an illustration with this equation, we could plug in a number of attendants x = 200 and then observe the total cost of the banquet hall y

If x=200

y=19x+350

y= 19×200+350

y= 3800+350

y= $4150

Therefore total cost of banquet hall if there are 200 guests at the banquet hall =$4150

The total cost of the banquet hall, if there are 200 guests at the banquet hall, is $4150.

Given that,

The equation y = 19x+350 represents the relationship between the total cost,

In dollars, y, to rent a banquet hall for a party, and the number of people attending, x.

The y-intercept is 350 and represents the total cost to rent the banquet hall. The slope is 19.

We have to determine,

The cost per person attending.

According to the question,

The equation y = 19x+350 representing the total cost for the banquet hall based on the number of people attending has both dependent and independent variables.

The independent variable is x which represents the number of people attending(each person costs $19).

Therefore,

To determine the total cost y which will be the cost of the banquet hall given the number of people attending x.

Then, the total cost of the banquet hall y is,

[tex]y=19x+350\\\\y= 19\times200+350\\\\y= 3800+350\\\\y= 4150[/tex]

Hence, the total cost of the banquet hall, if there are 200 guests at the banquet hall, is $4150.

1570 = 5 times [tex]\frac{22}{7}[/tex] times [tex]r^{2}[/tex]

1570 = 15.71[tex]r^{2}[/tex]

[tex]\frac{1570}{15.71}[/tex] = [tex]\frac{15.71 r^{2}}{15.71}[/tex]

Answer:

i. [tex]x^{2}[/tex] + 26x + 144 - 299 = 0

ii. x = 5

Step-by-step explanation:

The area of the figure = 299 cm²

The figure has a shape of a rectangle, so that;

Area of rectangle = length x width

length of the figure = 18 + x

width of the figure = 8 + x

Area of the figure = (18 + x) x (8 + x)

299 = (18 + x) x (8 + x)

299 = [tex]x^{2}[/tex] + 26x + 144

[tex]x^{2}[/tex] + 26x + 144 - 299 = 0

[tex]x^{2}[/tex] + 26x - 155 = 0

applying the trigonometric formula;

x = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex]) ÷ 2a

= (-26 ± [tex]\sqrt{(26)^{2} - 4(1*-155)}[/tex]) ÷ 2

= (-26 ± [tex]\sqrt{676 +620}[/tex]) ÷ 2

= (-26 ± [tex]\sqrt{1296}[/tex]) ÷ 2

= (-26 ± 36) ÷ 2

x = (-26 + 36) ÷ 2  OR x = (-26 -36) ÷ 2

  = 10 ÷ 2 OR -62 ÷ 2

  = 5 OR -31

Thus, x = 5

Answer:

Almonds cost $8 per pound and Cashews cost $10 per pound.

Assuming pounds of Almonds are denoted as a and Cashews are c, the formula will be:

8a + 10c = 60

Only Cashews:

This means that Almonds would be zero.

8(0) + 10c = 60

10c = 60

c = 60/10

c = 6 pounds of cashews

Only Almonds

8 * a + 10(0) = 60

8a = 60

a = 60/8

a = 7.5 pounds of almonds

A mixture of both.

We can use the formula above to calculate how many of each she can buy but she cannot buy more than 7.5 almonds or more than 6 cashews as she does not have enough money on her.

Assuming she wanted to buy 5 pounds of almonds, she would be able to buy:

8 * 5 + 10c = 60

40 + 10c = 60

10c = 60 - 40

c = 20/10

c = 2 pounds of cashews

Answer:

x = 4

y = 8

Step-by-step explanation:

From the question given above,

3.2x – 0.6y = 8 .......... (1)

–0.8x + 0.9y = 4 ......(2)

We shall determine the value of x and y by using elimination method as illustrated below:

3.2x – 0.6y = 8 .......... (1)

–0.8x + 0.9y = 4 ......(2)

Multiply equation 1 by 0.8 and equation 2 by 3.2

0.8 × (3.2x – 0.6y = 8)

2.56x – 0.48y = 6.4 ......... (3)

3.2 × (–0.8x + 0.9y = 4)

–2.56x + 2.88y = 12.8....... (4)

Next, add equation 3 and 4 together. This is illustrated below:

,,,,,, 2.56x – 0.48y = 6.4

+ –2.56x + 2.88y = 12.8

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

2.4y = 19.2

Divide both side by 2.4

y = 19.2 / 2.4

y = 8

Substitute the value of y into any of the equation to obtain the value of x. Here, we shall use equation equation 1. This is illustrated below:

3.2x – 0.6y = 8

y = 8

3.2x – 0.6(8) = 8

3.2x – 4.8 = 8

Collect like terms

3.2x = 8 + 4.8

3.2x = 12.8

Divide both side by 3.2

x = 12.8 / 3.2

x = 4

From the calculations made above,

x = 4

y = 8

Answer:

The slope is undefined and there is no y- intercept

Step-by-step explanation:

The line is equivelent to x=5

This is a vertical line so the slope is undefined and there is no y- intercept

Answer:

Slope: 0

Y-intercept: 5

Step-by-step explanation:

First, you need to move the equation into slope-intercept form.

Divide both sides by 3.

x = 5

Since there is no number to the right of the y - intercept, we just assume that the slope is 0.

Answer:

Step-by-step explanation:

Answer:

The value of x = 5

Step-by-step explanation:

It is clear that a traversal line is passing through two parallel lines.

It is also clear that:

The angle (35+2x)° and 60° are on the outside of the parallel lines and on the opposite side of the traversal. Therefore, (35+2x)° and 60° are Alternate Exterior Angles.

Please remember that Alternate Exterior Angles are congruent, so

35 + 5x = 60°

subtract 35 from both sides

35 + 5x - 35 = 60° - 35

5x = 25

divide both sides by 5

5x/5 = 25/5

x = 5

Therefore, the value of x = 5

Step-by-step explanation:

Well, first let's look at our trig identities. We can set up a cosine function using the given angle:

[tex]cos (46^{o} ) = \frac{x}{16}[/tex] (adjacent/hypotenuse)

Then, multiplying both sides by 16 gives us:

[tex]\huge\boxed{15 \pi \ \text{or} \approx 47.1 \ \text{in.}}[/tex]

Step-by-step explanation:

We can note a couple of relationships in this circle.

The arc length will be a fraction of the circumference. It will be the same fraction of the circumference that the central angle is to the entire circle.

First step: Find the circumference of the circle.

The circumference of any circle can be defined by the formula [tex]2 \pi r[/tex], where r is the radius of the circle. The radius is given to us, 30 in. We can now substitute that into the formula.

So our circumference is 60π.

Second Step: Find the ratio of the central angle of the arc to the total circle degrees

We know that the total amount of degrees in a circle is 360°. Therefore, we can set up a proportion to find the ratio between the central angle (90°) and the total circle measurement.

[tex]\frac{90}{360}[/tex]

Third Step: Equal out the two proportions and solve for the missing arc length

Now that we have our base proportion ([tex]\frac{90}{360}[/tex]), we can turn 60π into a proportion as well, leaving 60π as the denominator so we can solve for the arc length.

[tex]\frac{x}{60 \pi} = \frac{90}{360}[/tex]

We can now solve for x by cross multiplying.

Hope this helped!

apply the exponent rule 2^2 x 5^3= 5^2 x 5 = √2^2x5^2x5

√2^2x5^2x5= √2^2 √5^2 √5= √2^2√5^2√5

next, apply the radical rule

√2^2=2 =2√5^2 √5

√5^2=5 = 2x5√5

=10√5 which is also 22.36068 as a decimal

Answer:

We conclude that segment QR is the shortest.

Hence, option B is true.

Step-by-step explanation:

First, we need to determine the missing angle m∠R

Given the triangle Δ∠PQR

m∠P = 48°

m∠Q = 83°

m∠R = ?

We know the sum of angles of a triangle is 180°.

m∠P+m∠Q+m∠R = 180°

48°+83°+m∠R=180°

m∠R = 180° - 48° - 83°

m∠R = 49°

Thus, the value of m∠R = 49°

We know that the longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.

Here,

m∠P = 48° is the shortest angle.

As the side QR segment is opposite the smallest angle i.e. m∠P = 48°

Therefore, we conclude that segment QR is the shortest.

Hence, option B is true.
