Answer:

  4 ft = height

  10 ft = base

Step-by-step explanation:

The area of a triangle is given by ...

  A = 1/2bh

Filling in the given value, we get the relation ...

  20 = 1/2bh

  40 = bh

We know the factors of 40 are ...

  40 = 1×40 = 2×20 = 4×10 = 5×8

Of the numbers that area available, only the pair 4×10 will give the desired result.

The height is 4 ft; the base is 10 ft.

the half of 14.6 is 7.3 and you times it by 3.14 and its 22.922 i think

Answer:

1. 5.6%

2. 15%

3. 300 seats

4. 2.3%

Step-by-step explanation:

1. Percent error is A-E/E*100

A is actual and e is expected

376-356/356= 0.05618*100= 5.6%

2. 17-20/20=-0.15*100= 15%

3. This time we have to solve for the actual

x-250/250*100=20

x=300 seats

4. 342-350/350=-0.0228571429*100= 2.3%

Answer:

Andre budgets 312 dollars more for Groceries and Utilities than for savings.

Step-by-step explanation:

1.) Add the 15% and 9% to get 24% for Groceries and Utilities combined.

2.) The value of 24% of 5200 $1248 and the value of 18% (for savings.) is 936.

3.)Subtract 932 from 1240.

Answer:

30

Step-by-step explanation:

20+11=31

It can't be exactly 31 but it can be any number less than 31, so the nearest whole number down is 30

Answer:

Quadrilateral ABCD is a rhombus, because all four sides are congruent and adjacent sides are not perpendicular .

Step-by-step explanation:

Given :

A quadrilateral with its coordinates as follows:

Where  A (3, 1), B (4,4), C (7,5), D (6,2).

We will measure the length of the congruent sides by applying distance formula.

Distance formula = square root (x^2 - x^1)^2 + (y^2 - y^1)^2

So,  

AB = ( insert the coordinates using the formula )

BC = ( insert the coordinates using the formula )  

CD = ( insert the coordinates using the formula )

DA = ( insert the coordinates using the formula )

It all equals = squareroot 10

From the above measurement and looking into the diagram we can conclude that the Quadrilateral ABCD is a rhombus.  

In rhombus the adjacent sides are not perpendicular and its diagonals are of different length.

Answer:

#12.) 3m+2=17

3(5)+2=17

5*3=15

15+2=17

Step-by-step explanation:

Answer:

3 x 2 + 5 - 4 = 7 if its not 7 then try 15 most likely 7

m = 5 its already given on the top or its 17

7 x 5 - 2 > 12, m = 5 or the answer is 33 for the left side

for this you need to draw an empty circle on two and make the line bold starting from 2 to the 10.

Answer:

The point crosses over the y-axis

Step-by-step explanation:

Given

A change in the sign of x coordinate

Required

The effect on the point location

Assume the coordinate to be (x,y).

The above point is located in the first quadrant,

When the x value changes to negative i.e. (-x,y)

The point moves from the first quadrant to the second quadrant

This implies that, the point crosses over the y-axis.

Similarly, assume the coordinate to be (-x,-y).

The above point is located in the third quadrant,

When the x value changes i.e. (x,-y)

The point moves from the first quadrant to the fourth quadrant

This implies that, the point crosses over the y-axis.

Answer:

Mean and Median

Step-by-step explanation:

Given the data :

285,288,289,290,299,300,308,309,312,314

To summarize the data using a measure of centre, considering that the dataset doesn't show a great deal of variation we could use either the mean or median value.

The mean, x = Σx / n

n = sample size = 10

Σx = 2994 ; n = 10

x = 2994 / 10 = 299.4

Also the median value ;

1/2 * (n + 1)th term

1/2 * (10 + 1)th term

1/2 * 11

= 5.5 th term

= (5 + 6)th / 2

= (299 + 300) / 2

= 299.5

Answer:The value of the surface area (in square centimeters) of the cone is equal to the value of the volume (in cubic centimeters) of the cone. The formula for the surface area S of a cone is S=πr2+πrl, where r is the radius of the base and l is the slant height.

Step-by-step explanation:

Answer:

A cone is 360 triangles rotated in a circle, so find the hypotenuse of the triangle and multiplying it by 360 you would get the surface area of the cone

Answer:

6216

Step-by-step explanation:

This problem deals with exponential growth.

Final value: F

Present (initial) value: P

Rate of growth: r

Time in years = t

[tex] F = P(1 + r)^t [/tex]

[tex] F = 2900(1 + 0.1)^8 [/tex]

[tex] F = 6216 [/tex]

Answer: 6216

Answer:

volume = (length × Width × height)

(567/2) = (9×) × (17/4) × (w)

283.5 = 38.25w

w= 7.41inches

Answer:

a = 3/4

Step-by-step explanation:

Answer:

3(4+√2)

Step-by-step explanation:

Here we need to find the perimeter of the given figure. Here the given figure is made from a triangle and a square. The side lenght of the square is 3. We need to find the hypontenuse of the triangle in order to find Perimeter .

• Using Pythagoras Theorem :-

⇒ h² = p² + b²

⇒ h² = 3² + 3²

⇒ h² = 9 + 9

⇒ h² = 18

⇒ h = √[ 9 × 2 ]

⇒ h = 3√2 .

Therefore the perimeter will be ,

⇒ P = 3√2 + 3 + 3 + 3 + 3

⇒ P = 3√2 + 12

⇒ P = 3( 4 + √2)
