Gus has skydived 4 more times than Nico. Emma has skydived 16 times, how many times has Gus skydived?
Answers
We know that Emma has skydived 16 times, and also Emma has skydived twice as many times as Nico, so Nico has skydived:
[tex]\begin{gathered} \text{Emma}=2\cdot\text{Nico} \\ 16=2\cdot Nico \\ Nico=\frac{16}{2}=8 \end{gathered}[/tex]So, Nico has skydived 8 times.
Finally, we know that Gus has skydived 4 more times than Nico, so:
[tex]\begin{gathered} Gus=\text{Nico}\cdot4 \\ \text{Gus}=8\cdot4=32 \end{gathered}[/tex]Gus has skydived 32 times.

The pairs of angles that are linear pairs involving point F are:
A. ∠DFC and ∠CFG
D. ∠HFD and ∠CFD
E. ∠GFH and ∠GFC
F. ∠HFG and ∠DFH
What is a Linear Pair?When two angles that are adjacent to each other, (that is, they share the same vertex and the same side), are located on a straight line, these angles are linear pairs and are also supplementary angles.
Making reference to the image given, angles DFC and CFG share a common vertex F and a common side CF. Also, they lie on a straight line. Therefore, angle DFC and angle CFG are a linear pair.
Angles HFD and CFD share a common vertex F and a common side FD. They lie on a straight line. Thus, angle HFD and angle CFD are also a linear pair.
The same thing applies to angle GFH and angle GFC, as well as angle HFG and angle DFH.

Kaj earns $35 for 2 hours of work. If she makes a constant hourly wage, which table
represents the relationship between the number of hours she works and her total
earnings?
Answers
The table of values of the relationship between time and earnings is a linear relation
How to determine the table of values that represents the earnings?From the question, we have the following parameters:
Number of hours = 2 hours
Total earnings in this time = $35
Also from the question, we understand that:
She makes a constant hourly wage
A constant hourly wage implies that the table of values has a linear relationship
In this case, the linear relationship is represented as
A(t) = constant hourly wage * t
Where
A(t) represents the earnings
t represents the number of hours
So, we have
constant hourly wage * 2 = 35
Divide both sides of the equation by 2
So, we have
constant hourly wage = 17.5
Substitute constant hourly wage = 17.5 in A(t) = constant hourly wage * t
A(t) = 17.5 * t
Evaluate
A(t) = 17.5t
Using the values of t as:
t = 0, 2, 4, 6
We have the following table of values
Number of hours (t) || Amount earned
0 0

how many 14 goes into 78
Answers
The amount of times that 14 goes into 78 is; 5 times
How to carry out division of numbers?
We want to find how many 14 goes into 78.
Now, it is pertinent to note that this expression is used in our common daily lives for basic things of life. For example, if i want to know how many 10 dollars can go into 100 dollars, i will just divide 100 by 10.
Similarly another example is if i want to know how many 5 liters container of fuel would go into a 60 liters tank, i will just divide 60 by 5 to get the number.
In a similar vein, we can solve this question by dividing 78 by 14 to get;
78/14 = 5 ⁸/₁₄
This means 14 can only go in 5 full times as we will not count the fraction.

What is 50% of 100%?
Answers
25/50 = 0.5
Logic
Answer:
We need to determine 50% of 100 now and the procedure explaining it as such
Step 1: In the given case Output Value is 100.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 100 = 100%.
Step 4: In the Same way, x = 50%.
Step 5: On dividing the pair of simple equations we got the equation as under
100 = 100% (1).
x = 50% (2).
(100%)/(x%) = 100/50
Step 6: Reciprocal of both the sides results in the following equation
x%/100% = 50/100
Step 7: Simplifying the above obtained equation further will tell what is 50% of 100
x = 50%
Therefore, 50% of 100 is 50

What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Amy who is making all three smoothies for each of her x number friends. The first recipe uses 4 strawberries per smoothie, the second recipe uses 5, and the third recipe uses 6.
Number of friends [n] = x
Each of the three friends will get smoothies made from recipe 1, recipe 2 and recipe 3.
Then -
Number of strawberries needed for smoothie made from recipe 1 for x friends = n[1] = 4x
Similarly, for smoothies made from recipe 2 and 3 will need -
n[2] = 5x and n[3] = 6x number of strawberries.
Assume that total number of strawberries needed for making all the smoothies are y. Then, we can write -
y = 4x + 5x + 6x
y = 15x
Therefore, the total number of strawberries needed for making all the smoothies can be represented by the expression -

The rooftop of a 5-story building is 50 feet above the ground.
How long does it take the water balloon dropped from the
rooftop to pass by a third-story window at 24 feet?
Using the model h(t) = h, 16², solve the equation
h(t) = 24. (When you reach the step at which you divide
both sides by -16, leave 16 in the denominator rather than
simplifying the fraction because you'll get a rational
denominator when you later use the quotient property.)
Answers
With the help of the quotient, we know that the time the water balloon dropped from the rooftop is 1.3sec.
What do we mean by Quotient?In this example, the number divided by (15) is known as the dividend, and the number divided by (3 in this instance) is known as the divisor. The quotient is the outcome of the division.The quotient is the result of dividing two numbers by each other. As in the case of 8 ÷ 4 = 2, when the division produced the number 2, the outcome is the quotient. The dividend is 8 and the divisor is 4. The quotient and divisor are always less than their dividend, as you can see.So, h(t) = 24:
= 50Then, calculate as follows:
h(t) = - 1624 = 50 - 1616 = 50 - 2416 = 26 = 26/16t = √26/16t = 1.3secTherefore, with the help of the quotient, we know that the time the water balloon dropped from the rooftop is 1.3sec.

The lengths of the sides are enlarged and measures of the angles are preserved, so the triangles are similar.
The lengths of the sides change and the measures of the angles change as well, so the triangles look nothing alike.
The lengths of the sides are reduced and measures of the angles are preserved, so one triangle is a reduction of the other.

The plane containing point B and parallel to the plane CDH is plane ABF.
What is defined as the parallel plane?Parallel planes are spatial planes that never intersect. The length about any line segment perpendicular both to planes connecting two parallel planes is indeed the distance between them. There are an infinite number of perpendicular line segments between two parallel planes. Two of the perpendicular segments the above are line segments AB and CD. Any line segment that is perpendicular to both planes also has the shortest distance between them.As, from the diagram we can see that there are two plane passing from point B; plane ABF and ABC.
But plane ABC is intersecting the given plane CDH, while plane ABF is not.
