a father is 7 times the age that his son is now in 25 years time the father will be twice the age that his son will be then how old is the son now

Answers

Answer 1

Answer:

The son is 5 years old.

Explanation:

If the father is 7 times the age of a 5 year old the dad would be 35. In 25 years time the father will be 60 and in 25 years time his son will be 30. So the son will be half of his dads age and the dad will be twice the age of his son then. Hope this helps!

The area is 624.

The volume is 840.

Step-by-step explanation:

14 * 13 = 182

182 * 2 = 364

14 * 10 = 140

10 / 2 = 5

5 * 12 = 60

60 * 2 = 120

364 + 140 + 120 = 624

10 * 14 * 12 = 1,680

1,680 / 2 = 840

Answer:

Step-by-step explanation:

Choose the expressions that are equivalent to m∠AOB. Select all that apply.

Answers

Answer:

A, B, D, G, and H should be correct

Step-by-step explanation:

I've done the same problem and those were the answers shown

2∠DFE, DE, AB, ∠DOE, 2∠ACB are the equivalent expressions which are equivalent to m∠AOB.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

The inscribed angle of the same arc is half of the central angle, the central angle of DE is ∠DOE and the inscribed angle of DE is ∠DFE

∠DOE=2∠DFE=∠AOB

Now we get ∠AOB=2∠ACB

The angles which are equivalent to ∠AOB are

∠AOB=2∠DFE

∠AOB=DE

∠AOB=AB

∠AOB=∠DOE

Hence, 2∠DFE, DE, AB, ∠DOE, 2∠ACB are the equivalent expressions which are equivalent to m∠AOB.

Answer:

EGF= 27°

Step-by-step explanation:

EGF=FEG (opp ∠'s equal in isos triangle)

126 + 2x = 180° (int ∠' s of triangle =)

2x= 180-126

x= 54/2

x= 27

Therefore

EGF=FEG= 27°

Angle E and Angle G are both 27° because the angles equal the same and Angle F is 126° (as you already know) a triangle always equals 180° so all you have to do is subtract your given angle with 180 and then for this example I divided my answer by two for the two angles that are the same size.

Three sisters each purchased 2 shirts & a hat. The hat cost $26. If the
total was $205.50, then how much did each shirt cost?
A. $21.00 each shirt
B. $21.25 each shirt
C. $21.50 each shirt
D. $21.75 each shirt

Answers

Answer:

B. $21.25 each shirt

Step-by-step explanation:

Six shirts (3 sisters buying 2 shirts each) plus 3 $26 hats = 205.50

6s + 3(26) = 205.50

6s + 78 = 205.50

Subtract 78 from each side

6s = 127.50

Divide both sides by 6

s = 21.25

DJI and Hubsan are two
drone companies that want to introduce two
new drones. DJI wants to create a six-bladed drone with the battery pack
located at the center. DJI's drone has an apothem of 10 inches, covering
an area of 423 square inches. Hubsan's new drone is in the shape of an
octagon with an apothem of 8 inches, covering an area of 410 square
inches. Assume both drones are regular polygons.
Determine which drone has the biggest perimeter.

Answers

9514 1404 393

Answer:

Hubsan's drone has the greater perimeter

Step-by-step explanation:

The area is given by the formula ...

A = (1/2)Pa . . . . . where P is the perimeter and 'a' is the apothem

Then the perimeter is ...

P 2A/a

For DJI's drone, ...

P = 2(423)/10 = 84.6 inches

For Hubsan's drone, ...

P = 2(410)/8 = 102.5 inches

Hubsan's drone has the greater perimeter.

*use π on your sci calculator.

Surface Area =

Answer:

The answer is 0.8 in^2

Step-by-step explanation:

Data

diameter = 0.835 in

thickness = 0.077in

Roll of $ 2.00

Procedure

1.- Find the total number of nickels

# of nickels = 2/ 0.05

# of nickels = 40

2.- Calculate the Circumference

C = 2*pi*r

r = 0.077/2

r = 0.0385

C = 2*3.14*0.0385

C = 0.242 in

3.- Calculate the area of the thickness

Area = 0.242* 0.077*40

Area = 0.745 in^2

4.- Calculate the area of the base and the top

Area = 2*pi*r^2

Area = 2*3.14*(0.0382)^2

Area = 0.0093 in^2

5.- Calculate the total area of the roll

Total area = Area of the thickness + Area of the base and top

Total area = 0.745 + 0.0093

Total area = 0.7543 in^2 This is the result

Rounding to the nearest tenth = 0.8 in^2

What is the value of the unknown integer, n?

Answers

Answer:

I think 9 is the answer

Step-by-step explanation:

n + 6 greater-than-or-equal-to 15

n greater-than-or-equal-to 15 - 6

n greater-than-or-equal-to 9

n + 5 less-than 15

n less-than 15 -5

n = 10

So, less than 10 and greater-than-or-equal-to 9

n = 9 (I think so)
