help me with this math problem plz

Answer:

1803 square meter

Step-by-step explanation:

The surface area of a cone

A=πr(r+V(h2+r2))

where A is the surface area, r is the radius and h is the height

Given that the height of 54 meters and a diameter of 18 meters, the radius is half the diameter hence

radius = 18/2 = 9 m

A = 9π (9 + V(54^2 + 9^2))

= 9π (9 + V2997)

= 9π (9 + 54.74486)

= 1803.068976 Square meters

To the nearest square meter

A = 1803

Answer:

108 cm^2

Step-by-step explanation:

SA = PH + 2 * 1/2bh

SA = (3 + 4 + 5)(8) + 2 * (1/2) * 3 * 4

SA = 96 + 12

SA = 108

Answer: 108 cm^2

Answer:

10 miles

Step-by-step explanation:

6² + 8² = x²

36 + 64 = x

36 + 64 = 100

√100 = 10

Answer:

6) 1/2 + 1/2 + 1/2 + 1/2 = 4/2 = 2 inches.

7)  5/8 + 5/8 + 5/8 = 15/8 = 1 7/8 inches.

8)  We've added the 1/2-inch crystals together and the 5/8-inch crystals together.  Adding together the 3/4-inch crystals we have:

3/4 + 3/4 + 3/4 = 9/4 = 2 1/4 inches

Adding together the 3/8-inch crystals we have:

3/8 + 3/8 + 3/8 = 9/8 = 1 1/8 inches.

Totaling what we have:

2 + 1 7/8 + 2 1/4 + 1 1/8

= 2 + 1 7/8 + 2 2/8 + 1 1/8 (you can only add fractions if they have common denominators)

= 6 + 7/8 + 2/8 + 1/8 (add the whole numbers together)

= 6 10/8 = 6 + 1 2/8 = 7 2/8 = 7 1/4 inches.

9)  To find an average, we add all of the data points together and divide by the number of data points.  We added them in number 8.  Now we divide this total, 7 1/4, by 13:

7 1/4 ÷ 13 = 29/4 ÷ 13/1 = 29/4 × 1/13 = 29/52 inches average for the crystals.

Answer: Hi I  Can not seem to calculate the answer but I can give you a way to find 6th term or the geomatric sequence.

By substituting the values for a, r and n we can find the desired term that we want. r=7525, cancelling out the common factors, we get r=3. As we want the 6th term to find, substituting n=6,r=3&a=25 in the above equation, we get (25)(3)6−1. Simplifying this expression, we get 6075.

Step-by-step explanation:

If I can find the calculations correctly i will redo this answer! Have a nice day!

Answer:

y=50 but i dont know x, sorry about that its cause im in class rn lol

Answer:

x= 127

y = 50

Step-by-step explanation:

y = 180 -130(angles on a straight line)

y= 50

x= 360-(123+60+50). angles in a quadrilateral

x = 360- 233

x= 127

Answer: =12

Answer:

Step-by-step explanation:

convert either gram into kg or kg into gram

lets convert kg into g

1 kg=1000g

20kg=1000*24g

=20000g

450/20000*100%

450/200%

2.25%

first convert 450 g to kg = 0.45 kg

Now 0.45 kg as a. percentage of 20 kg = 0.45/20×100= 2.25%

Answer:

The df values for the A x B interaction are also 3,40

Step-by-step explanation:

The F-value for Factor A has df = 1, 40

The F-value for Factor B has df = 3, 40.

The df values for the A x B interaction are also 3,40

This is because the source of variation between columns has ( c- 1); rc(n-1) degrees of freedom and  the source of variation between  rows has (r-1); rc(n-1) degrees of freedom and the  source of variation of interaction

(between rows and columns)  has ( c-1) ( r-1); rc(n-1) degrees of freedom.

Therefore

Factor A:  ( c- 1); rc(n-1)    = 1,40

Factor B:    (r-1); rc(n-1)     = 3,40

Interaction : ( c-1) ( r-1); rc(n-1)   =  3*1,(40)= 3,40

where c refers to columns , r refers to rows and n refers to the total sample size.

Answer:

24

Step-by-step explanation:

Let the number of mangoes owned by Tulsa be T and that by Julie be J

If Tulsa has 4 times as many mangoes as Julie then

T = 4J

Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie

T + 6 = 5J

Solve both equations simultaneously by substitution

4J + 6 = 5J

Collect like terms

6 = 5J- 4J

J = 6

Since

T = 4J

T = 4 * 6

= 24

Hence Tulsa had 24 mangoes at first

Answer:

100 cm²

Step-by-step explanation:

Given that :

Length of prism = 20 cm

Height, h = 5cm

Width, w = 4 cm

The surface are of the side with clear material can be obtained by calculating the area of rectangule (front)

Area of rectangle = Length * height

Area = 20 * 5 = 100 cm²

Sum of 2 fifths of x and 6x and 6 in algebraic expression = 2/5 x +6x +6

Answer:

(14x+12)/5

Step-by-step explanation:

2 fifth of x = 2/5 * x= 2x/5

2 fifth of 6x = 2/5 * 6x = 12x/5

2 fifth of 6 = 2/5 * 6 = 12/5

2x/5 + 12x/5 + 12/5

= (2x+12x+12)/5

= (14x+12)/5

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!

Answer:

£714.00

Step-by-step explanation:

The first step is to set up expresssions for the two shares:

Let  x = the amount of one share.  The other share is 1785 - x.  You don't have to worry about which is smaller--that part will work out automatically!

The two shares are in the ratio of 2:3, so set up the proportion

[tex]\frac{x}{1785-x}=\frac{2}{3}[/tex]

Again, you don't have to worry--you could set up the proportion "upside down" and everything will work out in the end.

Solve the proportion for  x  by "cross multiplying" -- use the Means-Extremes Property of proportions.

[tex](3)(x)=(2)(1785-x)\\3x=3570-2x\\5x=3570\\x=714[/tex]

So one share is £714£ and the other is £1785 - £714 = £1071.

The smaller share is £714.

Answer:

B (- 5, 7 )

Step-by-step explanation:

Using the midpoint formula, then equate x and y coordinates

let coordinates of B = (x, y ) , then

[tex]\frac{x+1}{2}[/tex] = - 2 ( multiply both sides by 2 )

x + 1 = - 4 ( subtract 1 from both sides )

x = - 5

[tex]\frac{y-7}{2}[/tex] = 0

y - 7 = 0 ( add 7 to both sides )

y = 7

Coordinates of B = (- 5, 7 )
