Answers

Answer 1

Answer:

You would need to order 28 pounds. (27.27...)

Step-by-step explanation:

Let x be the number of cantaloupe. Then, 0.55x-=15.

0.55x=15

55x=1500

11x=300

x=300/11

x=27.27...

Answer 2
Final answer:

To make fruit salad using cantaloupe, you would need to order 28 pounds (AP) if you only need 15 pounds (EP) and the cantaloupe has a 55% yield.

Explanation:

To determine how much cantaloupe (AP) you would need to order, you need to consider the yield percentage. If the cantaloupe has a 55% yield, it means that 55% of the cantaloupe will be usable. So, you need to order more than 15 pounds (EP) to account for the reduced yield.



To calculate the amount of cantaloupe (AP) to order, you can use the formula:



AP = EP / Yield Percentage



Using the given values, the calculation would be:



AP = 15 pounds / 55% = 27.27 pounds



Rounded up to the nearest whole number, you would need to order 28 pounds of cantaloupe (AP) to obtain 15 pounds (EP) with a 55% yield.

If a rectangular prism with a length of 12 feet and a width of 9 feet has a surface area of 930 square feet find its height

Answers

Answer:

The height is 17 ft

Step-by-step explanation:

The surface area of a rectangular prism is

SA = 2(LW +WH + LH)

where L = length, W = width, and H = height

We know SA = 930, L = 12, and W = 9

930 = 2(12*9 +9H + 12H)

Divide each side by 2

930/2 = 2/2(12*9 +9H + 12H)

465 = (12*9 +9H + 12H)

Combine like terms

465 = 84+21H

Subtract 84 from each side

465-84 = 84-84+21H

357 = 21H

Divide by 21

357/21=21H/21

17 = H

The height is 17 ft

Answer:

Height is 17 ft.

Step-by-step explanation:

Given: Rectangular Prism is also called cuboid

          Length, L = 12 ft.    and   width, W = 9 ft.

          Surface Area of cuboid, SA = 930 ft.²

To find: height , H

The surface area of a rectangular prism or cuboid

SA = 2(LW +WH + LH)

930 = 2(12×9 +9H + 12H)

[tex]\frac{930}{2}=108 +9H + 12H[/tex]

465 = 108 + 9H + 12H

108 + 9H + 12H  = 465

21H + 108 =  465

21H = 465 - 108

21H = 357

[tex]H=\farc{357}{21}[/tex]

H = 17  

therefore, Height is 17 ft.

Answers

Answer:

For tingle #1

We can find angle C using the triangle sum theorem: the three interior angles of any triangle add up to 180 degrees. Since we know the measures of angles A and B, we can find C.

[tex]C=180-(A+B)[/tex]

[tex]C=180-(21.24+27.14)[/tex]

[tex]C=131.62[/tex]

We cannot find any of the sides. Since there is noting to show us size, there is simply just not enough information; we need at least one side to use the rule of sines and find the other ones. Also, since there is nothing showing us size, each side can have more than one value.  

For triangle #2

In this one, we can find everything and there is one one value for each.

- We can find side c

Since we have a right triangle, we can find side c using the Pythagorean theorem

[tex]b^2=a^2+c^2[/tex]

[tex]4^2=2^2+c^2[/tex]

[tex]16=4+c^2[/tex]

[tex]12=c^2[/tex]

[tex]c=\sqrt{12}[/tex]

[tex]c=2\sqrt{3}[/tex]

- We can find angle C using the cosine trig identity

[tex]cos(C)=\frac{adjacent}{hypotenuse}[/tex]

[tex]cos(C)=\frac{2}{4}[/tex]

[tex]C=arccos(\frac{2}{4} )[/tex]

[tex]C=60[/tex]

- Now we can find angle A using the triangle sum theorem

[tex]A=180-(B+C)[/tex]

[tex]A=180-(90+60)[/tex]

[tex]A=30[/tex]

For triangle #3

Again, we can find everything and there is one one value for each.

- We can find angle A using the triangle sum theorem

[tex]A=180-(B+C)[/tex]

[tex]A=180-(90+34.88)[/tex]

[tex]A=55.12[/tex]

- We can find side a using the tangent trig identity

[tex]tan(C)=\frac{opposite-side}{adjacent-side}[/tex]

[tex]tan(34.88)=\frac{7}{a}[/tex]

[tex]a=\frac{7}{tan(34.88)}[/tex]

[tex]a=10.04[/tex]

- Now we can find side b using the Pythagorean theorem

[tex]b^2=a^2+c^2[/tex]

Javier has 30 year mortgage on his 120,000 home hid bank required a 20% down payment and initially offers him a rate of 5.75% but he chose to buy 2 points and lower his rate.His current mortgage is 55.698 Taken all this into consideration ,what is the total financed price he paid for his home ? ​

Answers

Answer:226,432.80

Step-by-step explanation:

Final answer:

Javier's total financed price for his home, excluding the longer-term interest but including the cost of buying points, is $97,920. This total includes the initial mortgage of $96,000 after a 20% down payment on a $120,000 home and the $1,920 spent on purchasing two points to reduce the interest rate.

Explanation:

Javier's home cost $120,000, and he was required to make a 20% down payment. Twenty percent of $120,000 is $24,000, which is the down payment amount. Therefore, the initial loan amount is $120,000 - $24,000 = $96,000.

Buying points typically costs 1% of the loan amount per point to lower the interest rate by a certain percentage. It is not specified how much the rate was lowered by purchasing 2 points, but we can calculate the cost. Two points on a $96,000 loan is 2% of $96,000, which equals $1,920.

Thus, the total financed price of the home, not counting interest payments over the term of the mortgage but including the cost of the points, is the initial loan amount plus the cost of the points: $96,000 initial loan + $1,920 for points = $97,920.

A. Y=-5x+11
B. Y=-5x+1
C. Y=2x+1
D. Y=5x-1

Answers

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (1, 6) and (x₂, y₂ ) = (2, 1)

m = [tex]\frac{1-6}{2-1}[/tex] = - 5, hence

y = - 5x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 6), then

6 = - 5 + c ⇒ c = 6 + 5 = 11

y = - 5x + 11 → A

Answer:

Now to find the equation of a line that passes through the points (1,6) and (2,1) we will use two point slope form

Two point slope form : [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Substitute the values

[tex]y-6=\frac{1-6}{2-1}(x-1)[/tex]

[tex]y-6=-5(x-1)[/tex]

[tex]y-6=-5x+5[/tex]

[tex]y=-5x+11[/tex]

Answer:

LM = 23 units

Step-by-step explanation:

triangle KLN and triangle MLN are congruent.

The segment LM is equal to segment LK.

Also, MN is same as KN, thus we can write:

[tex]MN=KN\\25=14x-3\\25+3=14x\\28=14x\\x=2[/tex]

Since, x = 2, we can get the side length LM:

[tex]LM=LK=9x+5\\LM=LK=9(2)+5\\LM=23[/tex]

Hence, LM = 23 units

Answer:

LM = 23 units

Step-by-step explanation:

From figure we can see an isosceles triangle KNM

KN = NM

NL is the perpendicular from N to KM,

Therefore KL = LM

To find the value of x

From figure we can write,

14x - 3 = 25

14x = 25 + 3 = 28

x = 28/14 = 2

To find LM

LM = KL

we have KL = 9x + 5

Therefore LM = 9x + 5 = (9 * 2) + 5  = 23 units

In the following image, AB is parallel to DC, and BC is a transversal intersecting both parallel lines. The measure of angle ABC is 118°

Answers

Answer:

n° = 62°

p° = 62°

q° = 118°

v° = 84°

w° = 138°

Step-by-step explanation:

angle ABC is 118°

so

m° + 118° = 180

m° = 180° - 118°

m° = 62°

n° = m° = 62° (corresponding angles are equal since AB is parallel to DC, and BC)

p° = n° = 62° (vertical angles are equal)

q° + n° = 180° (linear pair angles)

q° + 62° = 180°

q° = 180° - 62°

q° = 118°

v° + 96° = 180° (linear pair angles)

v°  = 180° - 96°

v° = 84°

w° + 42° = 180 (linear pair angles)

w° = 180° - 42°

w° = 138°

Answer:

n° = 62°

p° = 62°

q° = 118°

m° + 118° = 180

m° = 180° - 118°

m° = 62°

n° = m° = 62° (corresponding angles are equal since AB is parallel to DC, and BC)

p° = n° = 62° (vertical angles are equal)

q° + n° = 180° (linear pair angles)

Mr. Gray's class is conducting an experiment to find the probability of pulling certain colors from a bag of 25 marbles. If 5 are purple, 2 are yellow, 4 are green, and the rest are black, what is the probability of drawing a green and black if the marbles are not replaced after they are picked?

Answers

Final answer:

The probability of drawing a green followed by a black marble from a bag containing 25 marbles without replacement is found by multiplying the individual probabilities of each event. These are 4/25 for the green marble and 7/12 for the black marble after the first draw.

Explanation:

The subject of this question is probability within the field of Mathematics, suitable for a High School level student. The probability of drawing a green and black marble without replacement is a two-step probability problem. Given that there are 5 purple, 2 yellow, 4 green, and the rest black out of 25 marbles, we first need to calculate the total number of black marbles, which is 25 - (5 + 2 + 4) = 14. The probability of drawing a green marble first is 4 out of 25, which simplifies to 4/25. After a green marble is drawn, there are now 24 marbles left in the bag, with 14 being black. Therefore, the probability of then drawing a black marble is 14/24 or 7/12. To find the combined probability of both events occurring sequentially, we multiply the individual probabilities: (4/25) * (7/12). This calculation will give us the final probability of drawing a green and then a black marble without replacement.

To express the area A of a square as a function of z, given that a wire of length 7x is bent into the shape of a square, we follow these steps:

The perimeter of the square is equal to the length of the wire, which is 7x.

Since the perimeter P of a square is 4 times one of its sides a, we can write P = 4a. Therefore, 7x = 4a.

To find the side length a, we divide 7x by 4: a = 7x/4.

The area A of a square is the square of one of its sides, so A = a². By substituting a with 7x/4, we get A = (7x/4)².

Finally, we need to write the equation in terms of z. Here, it seems there might be an issue with the question, as there is no direct relationship provided between x and z. Assuming there's a typographical error and that the wire length is actually 7z, we can write a = 7z/4 and A = (7z/4)².

If x is indeed correct and unrelated to z, more information is required to express A as a function of z.

What is the slope line y=5x+4

Answers

Answer:

The slope is 5

Step-by-step explanation:

This equation is in slope intercept form

y = mx +b

where m is the slope and b is the y intercept

y = 5x+4

where 5 is the slope and 4 is the y intercept

Answer:

The slope = 5

Step-by-step explanation:

The slope-intercept form of the equation of a line:

y = mx + b

m - slope

b - y-intercept

We have the equation y = 5x + 4

Therefore the slope is m = 5

What is the solution to the following system

Answers

C is the answer.............

Answer:

C. Is you answer

Step-by-step explanation:

What you have to do is you take the second equation and plug it into the y of the first equation to get

-2x^2+-3x^2+5=-5. You will then add the -2x^2 and the -3x^2 together to get

-5x^2+5=-5. You will then minus the 5 from both sides to get

-5x^2=-10. You will then divide the -5 from both sides to get

x^2=2. You will then square root it to get

x=sqrt2 and -sqrt2.

You will then plug the sqrt2 into the second equation into the x like this

y=-3(sqrt2)^2+5. and you answer wil be -1.

So C is your answer.

Answer:

x = 67.5 ft

Step-by-step explanation:

ΔNPM and ΔABM are similar. Therefore the sides are in proportion:

[tex]\dfrac{AM}{NM}=\dfrac{BM}{PM}[/tex]

We have

[tex]AM=71.5\ ft-22\ ft=49.5\ ft\\NM=71.5\ ft\\BM=x\\PM=97.5\ ft[/tex]

Substitute:

[tex]\dfrac{49.5}{71.5}=\dfrac{x}{97.5}[/tex]       cross multiply

[tex]71.5x=(49.5)(97.5)[/tex]

[tex]71.5x=4826.25[/tex]           divide both sides by 71.5

[tex]x=67.5[/tex]

A radioactive substance has a decay rate of 0.073 per minute. How many grams of a 120 gram sample will remain radioactive after 30 minutes? Round the answer to the nearest tenth of a gram, and do not include the unit in your answer.

Answers

Answer:

13.4 grams of a 120 gram sample will remain radioactive after 30 minutes.

Step-by-step explanation:

Given : A radioactive substance has a decay rate of 0.073 per minute.

To find : How many grams of a 120 gram sample will remain radioactive after 30 minutes?          

Solution :

Using decaying formula,  

[tex]y(t)=y_o e^{-rt}[/tex]

Where, [tex]y_o=120[/tex] is the initial amount

r=0.073 is the decay rate

t=30 minute is the time

Substitute the value in the formula,

[tex]y(30)=120\times e^{-0.073\times 30}[/tex]

[tex]y(30)=120\times e^{-2.19}[/tex]

[tex]y(30)=120\times 0.1119[/tex]

[tex]y(30)=13.428[/tex]

[tex]y(30)=13.4[/tex]

Therefore, 13.4 grams of a 120 gram sample will remain radioactive after 30 minutes.

Answer:

13.4

Step-by-step explanation:

Substitute the given values into the formula: A(t)=Pert. Where P is the initial mass, r is the rate of decay, and t is time.  Note, the rate is negative because we are finding the rate of decay.  

A=120e−(0.073)(30)≈13.4

So, about 13.4 grams will remain after 30 minutes.
