Answer:
[tex]\sqrt{8}[/tex]
We use the process of elimination to solve:
When we solve [tex](\sqrt{10})^{2}[/tex] we get 10 and we know that 10 is a integer and we know all integers are rational numbers, therefore, this is rational.
When we solve [tex]\sqrt{196}[/tex] we get 14 and we know its a rational number because it can be expressed as the quotient of two integers: 14 ÷ 1. Therefore this one is, rational.
0.63, The decimal 0.6 is a rational number. It is the decimal form of the fraction 6/10. A rational number is, by definition, any number that results when one integer is divided by another. Since both 6 and 10 are integers, or whole numbers, 0.6 is a rational number.
And lastly this leaves is with [tex]\sqrt{8}[/tex] and It is a non-terminating decimal with non-repeating digits. The number 2.828427125... can't be written in p/q form. Hence, the square root of 8 is a irrational number.

The animals at a safari park include gorillas, buffalo and wallabies. There are 24 more buffalo than there are gorillas. There are 7 times as many wallabies as there are gorillas. There are the same number of buffalo as there are wallabies. How many gorillas are there at the safari park?
Answers
The number of gorillas at the safari park is 4.
Let the number of gorillas at the safari park be x.
It is given that there are 24 more buffalo than there are gorillas.
Number of buffalo at the safari park = 24 + x
There are 7 times as many wallabies as there are gorillas.
Number of wallabies at the safari park = 7x
Now, the number of buffalo is the same as the number of wallabies.
So, we equate their numbers to find the value of x i.e. number of gorillas.
24 + x = 7x
7x - x = 24
6x = 24
x = 4
Therefore, the number of gorillas at the safari park is 4.

Answers
The most appropriate choice for division will be given by
Quotient of [tex]\frac{3382}{6}[/tex] is between 563 and 564
What is division?
The process of dividing a certain number into equal parts is called division
The answer obtained after division is called quotient and the other part is the remainder. The number which is divided is called the dividend and the number by which the dividend is divided is called divisor.
General rule of division
Divisor x Quotient + Remainder = Dividend
Here,
Quotient of [tex]\frac{3382}{6}[/tex] = 563
563 is between 562 and 564

June, Gavyn and Alex share some sweets in the ratio 3:5:4. June gets 39 sweets. How many sweets are there altogether?
Answers
Answer:
156
Step-by-step explanation:
This is a question in proportion and ratio
Since the ratio in which the sweets are shared is 3: 4 : 5 we can say that the proportion of total sweets that June gets is 3/(3 + 4 + 5) = 3/12 = 1/4
Let the total number of sweets be S
Then 1/4th of this will be June's share and we are given that the actual number June gets is 30
So we have 1/4 x S = 39
Multiplying both sides by 4:
4 x 1/4 x S = 39 x 4
S = 156
So there were 156 sweets altogether

find the area under the standard normal curve between z=0 and z=3
Answers
The area under the standard normal curve between z=0 and z=3 is 0.4987.
How to illustrate the information?It should be noted that because the normal distribution is symmetrical on both sides of the mean and is a continuous probability distribution, the right side of the center is the opposite of the left side.
The normal distribution was first termed by early statisticians who observed that the same shape repeatedly appeared in many distributions. The characteristics of normal distributions are as follows: Bell-like in its symmetry. The distribution's mean and median, which are both at its center, are equal.
The area will be illustrated as:
P(0 < Z < 3)
From the distribution table. In this case, it's important to look at the normal distribution table under the z score for the values of zero less than Z and Z less than 3. This will be:

Help ASAP solve for the value of Z
Answers
Answer:
z = 6
Step-by-step explanation:
The angle in the middle is a right angle with a measure of 90°
Together, all three angles, makes a stright angle which is measured 180°.
So we can write the following equation to find the value of z:
5z + 1 + 59 = 90 (we don'thave to include the middle angle since we already its measure)
add like terms
5z + 60 = 90 subtract 60 from both sides
5z = 30 divide both sides by 5
z = 6

The graph of the linear equation y = 20 + 10x for the given scenario is attached below.
The Cartesian coordinates of a specific point on the Euclidean plane can be thought of as each solution inside the scenario involving two variables.
A linear equation's solutions define a line inside the Euclidean plane, and each line may be viewed as the aggregate of all solutions to a linear model with two variables. This is how this category of equations came to be known as "linear." The solutions to a system of equations with integer variables collectively constitute a hyperplane in the Euclidean space with size n. (a subdomain of dimension n₁).Because linear equations may frequently accurately represent non-linear systems, they are used extensively in all branches of mathematics as well as in physics and engineering.Here the equation is given as y = 20 + 10x
Therefore at x = 0 , y = 20 and at y = 0, x = -2
This represents that the fixed monthly fee is 20 and the daily fee is 10.

Basic rate = $15
Working hours in a week = 48 hours
Total wages in a week = $ 15840
If no overtime is to be paid then according to question,
Amount paid to 1 worker = 48 X 15 = $ 720
Amount paid to x worker = 720x
