4 points
6 km/h
8 km/h
9 km/h
20 km/h​

Answers

Answer 1

Answer:

8km/h

Step-by-step explanation:

Answer 2

Given:

Distance ,d = 45 km

Time taken, t = 5 hours

To be calculated:

Calculate the average speed of a car ?

Formula used :

Average speed = Distance/Time

Solution:

We know that,

Average speed = Distance/Time

☆ Substituting the values in the above formula, we get

Average speed = 45 km / 5 h

= 9 km/h

Thus, the average speed of a car is 9 km/h .

Answers

Answer:

225 units squared

Step-by-step explanation:

Lets find the distance (the side length of the square)

D=sqrt((x2-x1)^(2)+(y2-y1)^(2))

plug in the coordinates:

D=sqrt((-5-(-5))^(2)+(12-(-3))^(2))

D=sqrt(0^(2)+15^(2))

D=sqrt(15^(2))

The total cost of a pair of shoes and a belt was $71.57. If the price of a pair of shoe was $1.79 less than the belt, what was the price of the pair of shoes?

Answers

Answer:

$34.89

Step-by-step explanation:

Here, we want to calculate the price of the pair of shoes.

Let the price of the belt be $x, we know that the price of pair of shoes would be x-1.79

so adding;

x + x-1.79 = 71.57

2x = 71.57 + 1.79

2x = 73.36

x = 73.36/2

x = $36.68

The price of pair of shoes = x-1.79 = 36.68-1.79 = $34.89

A cylindrical jar’s life has a radius of 4 inches. If the volume is 351.68in^3, approximately what is the height of the jar?

Answers

Answer:

7 inches

Step-by-step explanation:

The volume of a cylinder is calculated using

where r =4 inches is the radius and V=351.68 is the volume.

To find the height of the jar, we substitute these values and solve for h.

Divide both sides by 50.24 to get:

h=7 inches

Therefore the height of the jar is 7 inches

4 tan 45° +(2 sin 45°) (6 cos 45°)​

Answers

Answer:

value of 4 tan 45° +(2 sin 45°) (6 cos 45°)​ is 10.

Step-by-step explanation:

To solve this question we need to know value of

tan 45° = 1

sin 45° = [tex]1/\sqrt{2}[/tex]

cos 45° = [tex]1/\sqrt{2}[/tex]

we will be using above value sin the given expression as shown

[tex]4 tan 45 +(2 sin 45) (6 cos 45)​ = 4*1 + (2*1/\sqrt{2} )(6*1/\sqrt{2})\\ = 4 + (2/\sqrt{2}) (6/\sqrt{2})\\= 4 + (2*6)/(\sqrt{2}*\sqrt{2})\\= 4 + (12/2)\\= 4 + 6 = 10[/tex]

Thus, value of 4 tan 45° +(2 sin 45°) (6 cos 45°)​ is 10.

Answers

AP E X

Point H is the midpoint of FG, Line t intersects FG at a right angle and Line t is perpendicular to FG are true statements.

What is Coordinate Geometry?

A system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

A. Point H is the midpoint of FG: This statement must be true because line t is the perpendicular bisector of FG, which means it passes through the midpoint of FG and intersects FG at a right angle.

Therefore, H is the midpoint of FG.

B. Line t intersects FG at a right angle: This statement must be true because line t is the perpendicular bisector of FG, which means it intersects FG at a right angle.

C. FG = FH: This statement is not necessarily true.

While H is the midpoint of FG, the length of FH depends on the position of point H along line t. It could be greater than, less than, or equal to half the length of FG.

D. Line t is perpendicular to FG

This statement must be true because line t is the perpendicular bisector of FG, which means it is perpendicular to FG.

E. Line t is parallel to FG: This statement is not true. If line t were parallel to FG, it would not intersect FG at all, let alone at a right angle as required for a perpendicular bisector.

Therefore, Point H is the midpoint of FG, Line t intersects FG at a right angle and Line t is perpendicular to FG are true statements.

Find the area of a sector with a central angle of 180° and a diameter of 5.6 cm. Round to the nearest tenth.

Answers

Answer:

Step-by-step explanation:

Mathematically, the area of a sector can be calculated using the formula below;

area of sector = angle/360 * pi * r^2

From the question, angle = 180

pi= 22/7

r = d/2 = 5.6cm/2 = 2.8 cm

So the area of the sector is as follows;

A = 180/360 * 22/7 * 2.8^2

A = 2 * 22/7 * 2.8^2 = 49.28

which is 49.3 cm^2 to the nearest tenth

A number cube (dice) is rolled and a letter is selected from the word GIRAFFE. What is the compound probability of P ( 4 and F) P(EVEN NUMBER AND VOWEL)

Answers

Answer:

P (4 and F) = 1 in 21 or 4.76%

P(EVEN NUMBER AND VOWEL) = 3 in 14 or 21.43%

Step-by-step explanation:

The probability of rolling a four on a die is 1 in 6.

The probability of picking the letter F in the word GIRAFFE is 2 in 7.

Therefore:

[tex]P (4\ and\ F)=P(4)*P(F)\\ P (4\ and\ F)=\frac{1}{6}*\frac{2}{7}\\ P (4\ and\ F)=\frac{1}{21}= 4.76\%[/tex]

The probability of rolling an even number (2, 4 or 6) on a die is 3 in 6.

The probability of picking a vowel (A, E, I) in the word GIRAFFE is 3 in 7.

Therefore:

[tex]P (Even\ and\ Vowel)=P(Even)*P(Vowel)\\ P (Even\ and\ Vowel)=\frac{3}{6}*\frac{3}{7}\\ P (Even\ and\ Vowel)=\frac{3}{14}= 21.43\%[/tex]

Answers

Answer:

A

Step-by-step explanation:

The first thing to notice is the question says it is given that the person is between the ages 23 and 60, so we only care about those people. So then we want to know how likely it would be to pick someone with over 50 messages a month. So what you would do is take the amount of people who are between 23 and 60 and send over 50 text messages, and divide that by the total amount of people 23-60 (since that is the pool of people we have). Doing so we find there is 229 people aged 23-60 which then makes the answer 157/229 or A.

Answer:

y = 120

Step-by-step explanation:

Interior angles of a triangle add up to 180°

So,

x+87+33 = 180

x + 120 = 180

Subtracting 120 to both sides

x = 180-120

x = 60°

Now

Angles on a straight line also add up to 180°

So,

x+y = 180

60 + y = 180

Subtracting 60 to both sides , we get

y = 180-60

y = 120

ANSWER:
33+87+x=180(angle sum property)
120+x=180
x=180-120
x=60
If x =60 then ,
X+Y=180(linear pair)
60+Y=180
Y=180-60
Y=120

The perimeter of a rectangular yard which has one side that measures twenty-three metres equals 154 m. What are the dimensions of each side of the yard? PLEASE SHOW ME THE FORMULA YOU USE.

Answers

Answer: our rectangle is 23 meters of width and is 54 meters long.

Step-by-step explanation:

The perimeter of a rectangle is P = 2*W + 2*L

where W is the width and L is the length.

We know that W = 23m and P = 154m

then:

154m = 2*23m + 2*L

(154m - 2*23m)/2 = L = 54m

So our rectangle is 23 meters of width and is 54 meters long.
