Find the surface of each pyramid. round to the nearest tenth if necessary.

Answer:

1

Step-by-step explanation:

As per circle theorem rule, ∠GDE is twice than ∠GFE

10x +94 = 2 × (x+51)

10x + 94 = 2x + 102

8x = 8

x = 1

∠GDE= 10x+94° = 104°

∠GFE= x + 51° = 52°

Cookies-x

Cakes-y

x+y=64; he sold a total of 64 cakes and cookies.

x=3y-4; he sold 4 less (-4) than 3 times (3y) the number of cakes he sold.

Step-by-step explanation:

•Factors of 12 are 1, 2, 3, 4, 6 and 12 ... ... because 2 × 6 = 12, or 4 × 3 = 12, or 1 × 12 = 12

•Factors of 21: 1, 3, 7, 21

Answer:

Step-by-step explanation:

Construct a 2-columned table for each function.  Arbitrarily choose x values to go into the first column, values between -3 and +3:  

Example, for y = 3x + 1:

x    y = 3x + 1    (x, y)

--------------------------------

-2    3(-2) + 1     (-2, -5)

 0     3(0) + 1      (0, 1)

 1

 2

x is the "independent variable."  You choose the values, subject to the requirement that -3 < x < +3.  The function will return the y values, which are dependent upon the inputs x.  This will give you a good number (e. g., 5) points to plot.  Draw a line through these points to obtain a graph of

y = 3x + 1.   And so on.  You need to go through this procedure once for each of the 3 given functions.

Answer:

3.84m

Step-by-step explanation:

If the scale for this Water tower is 1 : 12 then this means that for every 1cm of the model, the actual water tower has 12cm. Therefore, in order to find the actual depth of the water tower we first need to multiply the depth of the model by 12.

32cm * 12 = 384cm

1 cm is equal to 0.01 m , therefore we now have to multiply the depth of the actual water tower which is in cm by 0.01 to get the actual depth in meters

384 * 0.01 = 3.84m

Answer:

The cost is $75

Step-by-step explanation:

Given

[tex]y = 25x[/tex]

Required

Cost of 3 cubic yards -- Missing from the question

The required means that: [tex]x = 3[/tex]

Plug in [tex]x = 3\\[/tex] to [tex]y = 25x[/tex]

[tex]y = 25 * 3[/tex]

[tex]y = 75[/tex]

The cost is $75

Answer:

x = 5

Step-by-step explanation:

These triangles are similar, so they are in proportion to each other. Because of this we can say [tex]\frac{2.5}{3.5}[/tex] (the lengths of the vertical sides) = [tex]\frac{x}{7}[/tex] (the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing  we get x = 5.

Step-by-step explanation:

The density formula is: Density =mass/vol

---> 2.76 =812.04 / Vol ---> Vol= 812.04 / 2.76= 294.22

The answer is 294.22

The volume of the emerald with mass 812.04 grams and density 2.76 grams/cubic cm is [tex]294.22 \: \rm cm^3[/tex] approximately.

Suppose that a finite amount of substance is there having its properties as:

Then, they are related as:

[tex]d = \dfrac{m}{v}[/tex]

For this case, we have:

Then, we have:

[tex]d = \dfrac{m}{v}\\\\v = \dfrac{m}{d} = \dfrac{812.04}{2.76} \approx 294.22 \: \rm cm^3[/tex]

Thus, the volume of the emerald with mass 812.04 grams and density 2.76 grams/cubic cm is [tex]294.22 \: \rm cm^3[/tex] approximately.

Answer:

has no solution.

Step-by-step explanation:

you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.

Answer:

infinite solutions  

Step-by-step explanation:

you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.

-7(y= 1.5x - 6) which equals the equation below

-7y= -10.5x-42 then combine the other equation

7y=10.5x+42 and that equals

Answer:

90x+ 50 y ≤  $40,000------  A

30x+ 80y ≤ $ 30,000-------  B

x + y ≤ 500 --- C

Step-by-step explanation:

Let x and y be the numbers of acres of potatoes and corn, respectively.

Then according to the given conditions

90x+ 50 y ≤  $40,000------  A

30x+ 80y ≤ $ 30,000-------  B

x + y ≤ 500 --- C

where both x and y equal to or greater than zero and cannot take a value less than zero.

x + y ≤ 500 --- C

gives us an idea that the total arable land is less or equal to  500 acres.

90x+ 50 y ≤  $40,000------  A

tells us that the total cost of planting potatoes and corn is less or equal to $ 40,000

30x+ 80y ≤ $ 30,000-------  B

tells us that the total cost of fertilizers for  potatoes and corn is less or equal to $ 30,000

In each of these x and y cannot have negative values or less than zero.

Answer:

u = -261

Step-by-step explanation:

Subtract 11 from both sides:

u/9 + 11= -8

u/9 + 11 - 11 = -18 -11

u/9 = -18 - 11

u/9 = -29

u/9 9 = -29 9

u= - 29 9

u = -261

Answer:

7 slides

Step-by-step explanation:

Sum of exterior angles of any polygon is always 360∘, it can never be 900∘. Hence, there cannot be any polygon like this.

It appears that by error the word "exterior" has been mentioned. In case sum of interior angles is 900∘,

total sum of all the angles is 900∘+360∘=1260∘.

But sum of each pair of interior and exterior angles add up to 180∘

we have 1260∘180∘=7 such pairs

and hence polygon has 7 sides.

Answer:

It's a heptagon, so 7 sides
