-36 is a perfect square?

Answer:

[tex] \boxed{\sf Height \ of \ parallelogram \ (h) = 8.4 \ cm} [/tex]

Given:

Area of parallelogram (A) = 31.5 cm²

Base of parallelogram (b) = 3.75 cm

To Find:

Height of parallelogram (h)

Step-by-step explanation:

Area of parallelogram (A) = Base (b) × Height (h)

31.5 = 3.75 × h

h × 3.75 = 31.5

h = [tex] \sf \dfrac{31.5}{3.75} [/tex]

h = 8.4 cm

The height of the parallelogram is 8.4cm with a base of 3.75cm and an area of 31.5 sq cm.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

The area of a parallelogram is base multiples by height as two triangles form a parallelogram.

Given, The area of the parallelogram is 31.5 sq cm and the base is 3.75 cm.

We know the area of a parallelogram is base×height.

∴ h×3.75 = 31.5.

h = (31.5/3.75) cm.

h = 8.4 cm.

Answer:

x<10

Step-by-step explanation:

First, we want to move all of our like terms to one side. In the inequality, the variable x on one side and our whole numbers on the other.

To do this you have to cancel out 0.5x on the right side. So you need to subtract 0.5 from both sides.

This leaves you with 15+x<25. Subtract 15 from both sides which leaves you with x<10

The heart will beat 604800 times in 6 days.

Number of minutes in a day = 1440 minutes

Number of minutes in 6 days = 1440 × 6 = 8640 minutes

Since the heart beats 70 times per minute, the number of times that it'll beat  in 6 days will be:

= 70 × 8640

Hey there! I'm happy to help!

If these are consecutive integers it means that they are one apart. Let's call our numbers x and y and create a system of equations. Our x will be the first integer and y will be the second.

y=x+1

4x+6y=96

We plug our y value into the second equation to solve for x.

4x+6(x+1)=96

We use the distributive property to undo the parentheses.

4x+6x+6=96

We combine like terms.

10x+6=96

We subtract 6 from both sides.

10x=90

And divide both sides by 10.

x=9

Since y is x+1, we know that y is 10.

Our integers are 9 and 10.

Answer: False

Step-by-step explanation:

Three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. However, a set of four or more distinct points will, in general, not lie in a single plane. Two lines in three-dimensional space are coplanar if there is a plane that includes them both.

Answer:

Coplanar means "lying on the same plane". Points are coplanar, if they are all on the same plane. Any three points are coplanar but with more than three points, there is the possibility that they are not coplanar so its false.

so with this in mind you must take 24 and divide it by the price of tea

24/3.50 is 6.8 so they max cups of tea he can buy is 6.

Hope this helps. :)

Step-by-step explanation:

The maximum number of cups he can buy will be 7.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a cup of coffee costs $4 and a cup of tea costs $3.50. If ray has $40 and has bought 6 cups of coffee.

6x4=$24

Divide 24 by 3.50 to get the number of cups.

24/3.50= 6.8

Therefore, the maximum number of cups he can buy will be 7.

Newtons 2nd law of motion

Step-by-step explanation:

Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion. Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. Before we can write down Newton’s second law as a simple equation giving the exact relationship of force, mass, and acceleration, we need to sharpen some ideas that have already been mentioned.

Given :

An irrational number , [tex]x=\sqrt{31}[/tex] .

To Find :

Two consecutive whole numbers that square root of 31 lies between.

Solution :

We know , square root of 36 is 6.

Also, square root of 25 is 5.

Now, we can see that [tex]\sqrt{31}[/tex] lies between 5 and 6. Also, both 5 and 6 are consecutive.

Therefore, between 5 and 6 is the solution.

Hence, this is the required solution.

The consecutive whole numbers that the square root of 31 lies between will be 5 and 6.

Consecutive numbers simply refers to the numbers that follow each other in a particular set.

The square root of 31 is 5.57

Therefore, it can be noted that 5.57 will be between 5 and 6.

Therefore, the numbers are 5 and 6.

Step-by-step explanation:

Use PEMDAS

1. (2x2)+2

You do 2x2 first which is 4 so then you do 4+2 which is 6

2. 6 divided by (5-3)

You do 5-3 first which is 2 then 6/2 (that's 6 divided by 2) which is 3

3. 6/6 x5

so you do 6 divided by 6 which is 1 then you get 1x5 which is 5.

Answer:

a. 0.63

b. 0.33

Step-by-step explanation:

Here is a probability question. When two events are independent, it means that the probability of one of the events happening has no effect on the probability on the other happening.

From the question, let P(H) be the probability of passing the history course while P(E) is the probability of passing the English course;

By representation;

P(H) = 0.75

P(E) = 0.84

a) Probability of passing both

This means that he passes history and also passes English;

Mathematically that would be represented as;

P(E) * P(H) = 0.84 * 0.75 = 0.63

b) Probability that he passes exactly one of the courses.

This means that he passes one and he fails the other. Mathematically, we should remember that the probability of an event not happening = 1 - probability of the event happening

Let P’(H) and P’(E) be the probability of failing the history and english courses respectively;

Thus; P’(H) = 1 - 0.75 = 0.25

while P’(E) = 1-0.84 = 0.16

Now the probability that he passes exactly one means he passes one and fails the other.

So in this case, we have two scenarios; He passes History and fail English or passes English and fails history.

Thus, we have;

[P(H) and P’(E) or P(E) and P’(H)]

In probability, and means multiplication while or means addition; thus we have;

{P(H) * P’(E) } + {P’(H) * P(E)}

= ( 0.75 * 0.16) + (0.25 * 0.84)

= 0.12 + 0.21 = 0.33
