Answer:

23.25 m^3

Step-by-step explanation:

First you must find the area of the base you find it like this:

A(area)=1/2(one half)3.1(base)2.5(height)

you get 3.875(this is the area of the base)

now you have to multiply the area of base times the area of height like this:

A(area)=3.875(area of base)6(height)=23.25

so the answer is 23.25m^3

Hope I'm right have a great day!

Answer:

3,400 grams

Step-by-step explanation:

The total amount of flour needed to make two batches of each recipe is 3400 grams.

1000 grams is equal to 1 kilogram.

Amount of flour used in one batch of the first recipe= 1 kilogram

So, the amount of flour used in two batches of the first recipe=2 kilogram =2000 grams.

Amount of flour used in one batch of the second recipe= 700 grams

So, the amount of flour used in two batches of the second recipe= 2*700=1400 grams.

Total amount of flour needed = 2000+1400 =3400 grams.

Hence, The total amount of flour needed to make two batches of each recipe is 3400 grams.

Answer:

a) The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].

b) The approximate distance between the high school and the stadium is 32 miles.

Step-by-step explanation:

a) The rest stop is located in the midpoint of the line segment between the high school and the stadium. Vectorially speaking, we use the following formula:

[tex]C(x,y) = \frac{1}{2}\cdot A(x,y) + \frac{1}{2}\cdot B(x,y)[/tex] (1)

Where:

[tex]A(x,y)[/tex] - Coordinates of the high school.

[tex]B(x,y)[/tex] - Coordinates of the stadium.

[tex]C(x,y)[/tex] - Coordinates of the rest stop.

If we know that [tex]A(x,y) = (3, 4)[/tex] and [tex]B(x,y) = (7,1)[/tex], then the coordinates of the rest stop are, respectively:

[tex]C(x,y) = \frac{1}{2}\cdot (3, 4) + \frac{1}{2}\cdot (7, 1)[/tex]

[tex]C(x,y) = \left(\frac{3}{2}, 2 \right) + \left(\frac{7}{2}, \frac{1}{2} \right)[/tex]

[tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex]

The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].

b) The approximate distance between the high school and the stadium ([tex]d[/tex]), in miles, is the product of the Length Equation of the Line Segment and the scale factor:

[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex] (2)

Where:

[tex]r[/tex] - Scale factor, in miles.

[tex]\Delta x[/tex], [tex]\Delta y[/tex] - Horizontal and vertical distances between the high school and the stadium, no unit.

If we know that [tex]r = 6.4\,mi[/tex], [tex]\Delta x = 4[/tex] and [tex]\Delta y = -3[/tex], then the distance between the high school and the stadium is:

[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex]

[tex]d = (6.4\,mi)\cdot \sqrt{4^{2}+(-3)^{2}}[/tex]

[tex]d = 32\,mi[/tex]

The approximate distance between the high school and the stadium is 32 miles.

Answer:

Net Earnings = $65

Step-by-step explanation:

Money deposited in saving account = $2500

Interest rate = 5% pa = 5% of 2500 = $125

Fee = $5 (monthly). So annual fee = 12 x 5 = $60

So, net earning = Interest Earning - Annual Fee

= $125 - $60 = $65

Ok I am not so sure about this one, since this was a LOT of counting, and unless you want to see 5 pages of calculations, I'm just going to go on a limb and say trust me. However, if you really want to see for yourself, I'll give you a hint. For the first 1***1 numbers, the sum is 1440. For the 2***2 numbers, the sum is 1683. Try to calculate this to 9***9 to find the answer! Again, not sure about my answer if it's wrong, sorry!

Answer:

∠C=39°

Step-by-step explanation:

The interior angles of a triangle will always have a sum of 180°.

∠A+∠B+∠C=180°

78°+63°+∠C=180°

∠C=180°-78°-63°

∠C=39°

Answer:

39 degrees

Step-by-step explanation:

All triangles will add up to 180 degrees. So, you know that angle C added with angles A and B will equal 180. if you take 180, minus 78, minus 63, you get the answer 39.

Answer:

Cost of each jersey = $13.6

Step-by-step explanation:

Given:

Cost of each team cup = $16

Total amount spend = $296

Total number of team cup = 10

Total number of jersey = 10

Find:

Cost of each jersey

Computation:

Assume;

Cost of each jersey = c

So,

16(10) + (c)(10) = 296

160 + 10c = 296

10c = 296 - 160

10c = 136

c = 136 / 10

Cost of each jersey = $13.6
