A plane is at Manchester, which is 170 km north of Worcester. The plane flies in a straight line for 230km and lands in Cambridge, which is directly east of Worcester.

Answer:

A) 62

Step-by-step explanation:

The angle of BCA is 62 degrees. thus, Option B. is correct.

The sum of the angles of the quadrilateral is 360 degrees.

We need to find the ∠BCA:

∠OBD = 90  

∠OAD = 90  

So angles in quadrilateral BOAD

56, 90, 90 and∠ BOA

56 + 90 + 90 + ∠BOA = 360

∠BOA = 360 - 90 -90 - 56

∠BOA = 124

∠BCA is angle at circumference

∠BOA = 124, is the angle at centre

Angle at Centre = 2 x Angle at circumference

Angle at Circumference = Angle at Centre / 2 = 124/2 = 62

∠BCA = 62 degrees

thus, Option B. is correct.

Answer:

45[tex]\pi[/tex]

Step-by-step explanation

The space that the package occupies is the volume of the cylinder. The volume of an object is the 3 dimensional capacity of the object.

Volume of a cylinder = h

Lets say r is the radius and h is the height of the cylinder.

Given that; h = 5 feet and r = 3 feet.

The required volume = [tex]\pi[/tex] ×  × 5

                                  = [tex]\pi[/tex]  × 9 × 5

                                 = 45[tex]\pi[/tex] cubic feet

Answer:

37.5%

Step-by-step explanation:

The percentage of the punch in cranberry juice will be 37.50%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Diane makes fruit punch with 3 cups of cranberry juice, 2 cups of mandarin orange juice, and 3 cups of watermelon juice.

The percentage of the punch in cranberry juice will be given as,

P = [3 / (3 + 3 + 2)] x 100

P = (3 / 8) x 100

P = 0.375 x 100

P = 37.50%

The percentage of the punch in cranberry juice will be 37.50%.

There are 8 girls

Step-by-step explanation:

We see that right now there are 6 more boys than girls and if there were 2 girls there would be 14 boys meaning there would be 12 more boys than girls if you continue in this pattern you would get-

7:1= 6 more boys                   35:5=30 more boys                                                

14:2= 12 more boys                42:6= 36 more boys

21:3=18 more boys                 49:7= 42 more boys

28:4= 24 more boys               56:8= 48 more

This shows us that if there are 8 girls in  group there are 56 boys meaning there are 48 more boys than girls if the group had 8 girls

Answer:

The solution is (8,12)

Answer:

C  None of the above

Step-by-step explanation:

Here are the required options

Choose all answers that apply

A  (5g+3h).8  

B  (5g+3h).6  

C  None of the above

Given the expression;

(5g+3h+4).2

Expand

(5g+3h+4).2

= 2(5g+3h+4)

= 2(5g) + 2(3h) + 2(4)

= 10g+6h+8

Checking option A;

(5g+3h).8

Expand

= 8(5g+3h)

= 8(5g) + 8(3h)

= 40g+24h

Checking option B:

(5g+3h).6

Expand

= 6(5g+3h)

Using the distributive law;

= 6(5g) + 6(3h)

= 30g+18h

Since none of the expressions for A and B is equivalent to 10g+6h+8, hence NONE of the options are correct

Answer:

y = 1/2x + 5

Step-by-step explanation:

The formula for an equation is y = mx + b

m is the slope. It is given

y = 1/2x + b

b is the y-intercept

In this case, we must substitute to find the y-intercept

We are given coordinate pair (4,7)

Plug our pair in and we get => 7 = 1/2(4) + b

=> 7 = 2 + b

easily, we find b = 5

We get our equation: y = 1/2x + 5
