Answer:

There are 7,725 square feet of grass on the trapezoidal field

Step-by-step explanation:

Here in this question, we are interested in calculating the square feet of grass present on the trapezoidal field.

What this question is actually asking us is to calculate the area of the trapezoid-shaped grass field.

To calculate this area, what we need to do

simply is to use the formula for the area of a trapezoid.

Mathematically, the area of a trapezoid can be calculated using the formula;

Area of trapezoid = 1/2 * (a + b) * h

where a and b refers to the length of the parallel lengths of the trapezoid and h refers to the height of the trapezoid.

From the question;

a, b = 81ft and 125 ft

h = 75 ft

Substituting these values, we have :

Area = 1/2 * (81 + 125) * 75

Area = 1/2 * 206 * 75 = 83 * 75 = 7,725 ft^2

Answer and explanation:

Benchmark fractions are fractions that are used as references in measuring other fractions. They are easily estimated and so can be used in measuring more "specific" fractions such as 1/5, 7/9, 3/7, 1/3 etc. If I wanted to measure 1 1/3cm for instance using a calibrated ruler, having centimeter measurements, I would first find 1cm on the ruler and then find half of one centimeter. Seeing that half is bigger than 1/3 but close, I could then estimate 1/3 to be somewhere less than 1/2 but a bit close to it

Answer:

Total cost of producing is 2800.

Step-by-step explanation:

Given

Ratio of profit, material cost and production labour is 5:7:13.

Material cost is 840 more than that of labour cost.

To find:

Total cost of producing the article.

Solution:

Cost of producing the article includes material cost and the labour cost.

Profit will not be included in the production cost because profit comes in the picture after the article is sold.

We are given that, the ratio is:

Profit: Material Cost: Production Labour = 5:7:13

So, we can let Material Cost = 7[tex]x[/tex] and

Production Labour = 13[tex]x[/tex]

As per the question statement:

[tex]13x-7x=840\\\Rightarrow 6x=840\\\Rightarrow \bold{x=140}[/tex]

Total cost of producing = Material Cost + Production Labour

Total cost of producing = 7[tex]x[/tex] + 13[tex]x[/tex] = 20[tex]x[/tex] = 20 [tex]\times[/tex] 140 = 2800

So, Total cost of producing is 2800.

The supplement is 135°

b) [tex]108+x=180[/tex]

Solve. Subtract 108 from both sides:

[tex]108-108+x=180-108\\\\x=72[/tex]

The supplement is 72°

d) [tex]x+90=180[/tex]

Solve. Subtract 90 from both sides:

[tex]x+90-90=180-90\\\\x=90[/tex]

The supplement is 90°

a) [tex]x+65=180[/tex]

Solve. Subtract 65 from both sides:

[tex]x+65-65=180-65\\\\x=115[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

The question is not complete, i think the correct question is:

Kareem and Kira each opened a savings account today. Kareem opened his account with a starting amount of $770, and he is going to deposit $30 per month. Kira opened her account with a starting amount of $935, and she is going to deposit $45 per month. Let x be the number of months after today

Let us assume that each acre of land on Mars cost $107.

a) For Kareem account, she started with $770 and would deposit $30 per month. Let y represent the money deposited after x month. This can be represented by the equation:

y = 770 + 30x

Since each acre cost $107, 10 acre would cost $1070. Therefore $1070 is needed to be saved. To find the number of months, substitute y = 1070 and solve. Therefore:

1070 = 770 + 30x

1070 - 770 = 30x

30 x = 300

x = 300/30

x = 10

It would take 10 months for Kareem to buy 10 acres of land

b) For Kira account, she started with $935 and would deposit $45 per month. This can be represented by the equation:

y = 935 + 45x

Since each acre cost $107, 10 acre would cost $1070. Therefore $1070 is needed to be saved. To find the number of months, substitute y = 1070 and solve. Therefore:

1070 = 935 + 45x

1070 - 935 = 45x

45 x = 135

x = 3

It would take 3 months for Kira to buy 10 acres of land

Answer:B&D

Step-by-step explanation:

Answer:

Hey there!

The question is basically asking for you to solve a fraction subtraction problem, and fill in the missing values as you solve.

The given problem is 2/3 - 1/2. However, we can't subtract right now, since the denominators are different.

2/3 can be expressed as 4/6, and 1/2 can be expressed as 3/6.

Thus, the missing denominator in line one is 6 and the missing numerator in line one is 3.

4/6-3/6=1/6.

Thus, the numerator in line two should be 1.

From top to bottom, the numbers in the three boxes should be 6, 3, and 1.

This can be a confusing topic, especially if you're just learning it. Let me know if you need additional help :)

Answer:

[tex]f'(x) = 3-2\cdot x[/tex]

Step-by-step explanation:

Let be [tex]f(x) = -x^{2}+3\cdot x[/tex], such that:

[tex]f'(x) = \frac{f(x+h)-f(x)}{h}[/tex]

Hence,

[tex]f(x+h) = -(x+h)^{2}+3\cdot (x+h)[/tex]

[tex]f(x+h) = -(x^{2}+2\cdot x\cdot h + h^{2})+3\cdot x + 3\cdot h[/tex]

[tex]f(x+h) = -x^{2}+(3-2\cdot x) \cdot h - h^{2}+3\cdot x[/tex]

[tex]f(x) = -x^{2}+3\cdot x[/tex]

Then,

[tex]f'(x) = \frac{-x^{2}+(3-2\cdot x)\cdot h-h^{2}+3\cdot x+x^{2}-3\cdot x}{h}[/tex]

[tex]f'(x) = \frac{(3-2\cdot x)\cdot h-h^{2}}{h}[/tex]

[tex]f'(x) = 3-2\cdot x -h[/tex]

If [tex]h \longrightarrow 0[/tex], then:

[tex]f'(x) = 3-2\cdot x[/tex]

Answer:500 cm

Step-by-step explanation:

Given

height of ethan = 180 cm

length of shadow =144 cm

Distance of ethan from lamp =256 cm

from diagram, we can write

[tex]\Rightarrow tan \theta =\frac{FC}{EC}\quad \ldots(i)[/tex]

[tex]\Rightarrow \tan \theta =\frac{AB}{BE}\quad \ldots (ii)[/tex]

From (i)  and (ii)  we get

[tex]\tan \theta =\frac{FC}{EC}=\frac{AB}{BE}[/tex]

[tex]\Rightarrow \frac{180}{144}=\frac{h}{144+256}[/tex]

[tex]\Rightarrow h=\frac{180}{144}\times 400[/tex]

[tex]\Rightarrow h=500\ cm[/tex]

So, height of lamp post AB is [tex]500\ cm[/tex]

Thus, when x = -1

[tex] f(-1) = 3(-1)^2 - 8(-1) + 2 [/tex]

[tex] f(-1) = 3*1 + 8 + 2 = 3 + 8 + 2 [/tex]

[tex] f(-1) = 13 [/tex]

[tex] f(0) = 3(0)^2 - 8(0) + 2 [/tex]

[tex] f(0) = 0 - 0 + 2 = [/tex]

[tex] f(0) = 2 [/tex]

[tex] f(1) = 3(1)^2 - 8(1) + 2 [/tex]

[tex] f(1) = 3*1 - 8 + 2 = 3 - 8 + 2 [/tex]

[tex] f(1) = -3 [/tex]

[tex] f(2) = 3(2)^2 - 8(2) + 2 [/tex]

[tex] f(2) = 3*4 - 16 + 2 = 12 - 16 + 2 [/tex]

[tex] f(2) = -2 [/tex]

[tex] f(3) = 3(3)^2 - 8(3) + 2 [/tex]

[tex] f(3) = 3*9 - 24 + 2 = 27 - 24 + 2 [/tex]

[tex] f(3) = 5 [/tex]

The correct table for the function is the last option.

Follow // Followback

The line of y=x-2 intersects the x axis at (2,0).

To find the points where line intersect the x-axis.

Coordinate geometry is defined as the study of geometry using the coordinate points. Coordinate geometry is required to provide a link between algebra and geometry through the use of line and curve graphs.

The x-axis is defined as being at y=0 (look at a graph, the x-axis intersects the y-axis at y=0). Therefore, all you need to do is put in 0 for y, and solve for x.

  y=x-2

 put in 0 for y

 0=x-2

add 2 to both sides

2+0=x-2 +2  

 x=2

Therefore the line of y=x-2 intersects the x axis at (2,0).

Answer:

The missing side is 8 ft long

Step-by-step explanation:

According to Pythagoras theorem "It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides"
