Answer:

22.2m

Step-by-step explanation:

vol of a sphere = 4/3 x pi x r^3

vol of a hemisphere is 1/2 the vol of a sphere, so vol of a hemisphere= 2/3 x pi x r^3

2/3pi x r^3 = 257

Divide both sides by 2/3pi

r^3 = 122.708

Cube root both sides.

r = 11.077

Diameter is twice the radius, so diameter = 22.154m

To the nearest 10th of a meter this is 22.2m.

Answer:

[tex] y = \frac{3}{7} x + 3 [/tex]

Step-by-step explanation:

Line is passing through the points (0, 3) and (7, 6)

So, y-intercept (b) = 3

Slope of the line (m) = (6 - 3)/(7 - 0) = 3/7

Equation of line in slope-intercept form is given as :

y = mx + b

Plugging the values of m and b in the above equation, we find:

[tex]y = \frac{3}{7} x + 3 \\ [/tex]

Step-by-step explanation:

Sum the parts of the ratio, 2 + 3 + 5 = 10 parts

Divide the profit by 10 to find the value of one part of the ratio.

$450 000 ÷ 10 = $45 000 ← value of 1 part of the ratio, then

2 parts = 2 × $45 000 = $90 000 ← Lea's share

3 parts = 3 × $45 000 = $135 000 ← Paul's share

5 parts = 5 × $45 000 = $225 000 ← Tynos' share

Answer:

1/8 m³

Step-by-step explanation:

Given that:

Side length of block, s = 1/4

Volume of block, V

V = s³

Volume of block = (1/4)³ = 1/4 * 1/4 * 1/4 = 1 /64

The rectangular prism takes 8 of this blocks :

Hence, the volume of the rectangular prism is :

Number of blocks * Volume per block

8 * 1 /64

8 /64

= 1/8 m³

Step-by-step explanation:

Answer:

d=101

Step-by-step explanation:

If 11 is being multiplied by t, and t is 11, we multiply 11 by 11, we get 121.

After adding that to our equation, we get -20 + 121, which equals 101.

Therefore d=101

The value of d, when t = 11 is equal to 141.

An expression in mathematics defines a relationship between one variable (the independent variable, x)  and another variable (the dependent variable, y). For example -

f(x) = 4x + 6

Given is the following equation -

d = - 20 + 11t

We have -

d = - 20 + 11t

for t = 11, we get -

d = 20 + 11 x 11

d = 20 + 121

d = 141

Therefore, the value of d, when t = 11 is equal to 141.

Answer:

Step-by-step explanation:

Volume for triangular prism = 1/2 * b * l * h

we are given the length and the height but not the base.

since it is a right triangle we can use the Pythagorean theorem a^2 + b^2 = c^2

13.3^2 + b^2 = 20.5^2

176.89 + b^2 = 420.25

b^2 = 243.36

b = [tex]\sqrt{243.36}[/tex] = 15.6

1/2 (15.6)(13.3)(16) = 1659.84

Front: 15.6 x 13.3 = 207.48

Back: 15.6 x 13.3 = 207.48

Left: 15.6 x 16 = 249.6

Right: 13.3 x 16 = 212.8

Bottom: 20.5 x 16 = 328

207.48 + 207.48 + 249.6 + 212.8 + 328 = 1205.36

Answer:

m<ADC = 107

Step-by-step explanation:

You need to know three things to solve this problem.

1) Opposite angles of an inscribed quadrilateral are supplementary.

2) The measure of an inscribed angle is half the measure of its subtended arc.

3) The sum of the measures of all the arcs of a circle is 360 deg.

From 1) we get:

m<A + m<C = 180

72 + m<C = 180

m<C = 108

From 2) we get:

m<C = (1/2)m(arc)BAD

108 = (1/2)[m(arc)AB + m(arc)AD]

216 = m(arc)AB + 122

m(arc)AB = 94

From 3) we get:

m(arc)AB + m(arc)BC + m(arc)CD + m(arc)DA = 360

94 + 120 + m(arc)CD + 122 = 360

m(arc)CD = 24

From 2) we get:

m<ADC = (1/2)m(arc)ABC

m<ADC = (1/2)[m(arc)AB + m(arc)BC]

m<ADC = (1/2)[94 + 120]

m<ADC = 107

Answer: there are 11 calories in one glass of milk and 14 calories in one snack bar.

Step-by-step explanation:

Take milk to to be M and snack bars to be S.

Use algebra, so

2m + 3s = 64 and also

4m + 2s = 72

Multiply the top equation by 2 so both have 4m, so

4m + 6s = 128 and also

4m + 2s = 72

Then minus the numbers form the top equation by the bottom equation, so

4m + 6s = 128

- - -

4m + 2s = 72

This gives you 4s=56 so divide by 4 so s=14

No put 14 into the equation for s and rearrange to solve for m, so

2m+3s=64 So

2m+3x14=64

2m+42=64

Then minus 42

2m=22

m=11

Answer:

23

-71

Step-by-step explanation:

11 - (-12) = ?

-22 - 49 = ?

11 - ( -12) = 11 + 12 = 23

-22 - 49

subtracting a negative from a negative is like adding a positive to a positive it has the same affect just a different sign

-22 - 49 = -(22 + 49)

22 + 49 = 71

-(71) = -71
