Diana worked on her science project for 513 hours. Gabe worked on his science project 114 times as long as Diana. Paula worked on her science project 34 as long as Diana. How long did Gabe and Paula work on their projects?
Answer:
Gabe worked for 6 2/3 hours and Paula worked for 4 hours.
Step-by-step explanation:
It is given that,
Diana worked on her science project for 5 1/3 hours.
Gabe worked on his science project 1 1/4 times as long as Diana.
Paula worked on her science project 3/4 as long as Diana.
Solution,
ATQ,
Gabe worked for :
[tex]5\dfrac{1}{3}\times 1\dfrac{1}{4}\\\\=\dfrac{16}{3}\times \dfrac{5}{4}\\\\=\dfrac{20}{3}\ h\\\\=6\dfrac{2}{3}\ h[/tex]
Pauls worked for :
[tex]\dfrac{3}{4}\times 5\dfrac{1}{3}\\\\=\dfrac{3}{4}\times \dfrac{16}{3}\\\\=4\ h[/tex]
Hence, Gabe worked for 6 2/3 hours and Paula worked for 4 hours.

write a linear function with f with f (5) = -1 and f (0) = -5
Answer:
5y = 4x-25
Step-by-step explanation:
Let f(x) be regarded as y
So we have two points
(5,-1) and (0,-5)
We start by finding the slope of the line connecting the two points
m = y2-y1/x2-x1
m = -5+1/0-5 = -4/-5 = 4/5
The general equation of a straight line is;
y = mx + b
where m
is slope and b is the y-intercept
we already have the slope as 4/5
So;
y = 4x/5 + b
To get b, substitute one of the points
Let us use (0,-5)
-5 = 4(0)/5 + b
so b = -5
The equation is;
y = 4x/5 - 5
Multiply through by 5
5y = 4x - 25

In a unit circle, the radian measure of the central angle is equal to the length of the ______
A. Intercepted arc
B. Radius
C. Diameter
D. Circumference
Answer:
A. Intercepted arc.
Step-by-step explanation:
From Geometry we know that arc ([tex]s[/tex]), dimensionless, is measured by the following equation:
[tex]s = \theta \cdot r[/tex] (1)
Where:
[tex]\theta[/tex] - Central angle, measured in radians.
[tex]r[/tex] - Radius, dimensionless.
If the circle has a radius of 1. Then, we notice that arc is directly proportional to the central angle. Hence, the right answer is A.
The Cellular connection charges $60 for a phone and $29 per month under its economy plan. Write an equation that can be used to determine the total cost, c of operating a Cellular connection phone for t months. Then, find the total cost for 6 months
The equation for total cost will be c = 60 + 29t and the total cost for 6 months will be $234.
It is given that charge of cellular connection for a phone is $60 and Economy plan is of $29 per month.
We have to find out the equation for total cost and the value of total cost for 6 months.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , multiplication , etc.
As per the question ;
Charge of cellular connection for a phone = $60
and
Economy plan of cellular connection = $29 per month
Let's assume c be total cost , t be no. of months.
So ;
The economy plan charges for t months will be ;
= 29 × t
and
The equation for total cost (c) will be ;
c = 60 + 29t
Also ;
The total cost for t = 6 months will be ;
c = 60 + 29 × 6
c = 60 + 174
c = $234
Thus , the equation for total cost will be c = 60 + 29t and the total cost for 6 months will be $234.

Tell whether (-1,3) is a solution of the inequality whose graph is shown.
Answer: No.
Reason: (-1, -3) is (x, y) so, let's find -1 on the X scale first. Alright, -1 is in the blue, which is a great start. Now, it's -3 on the Y portion. And when you graph that, it's not in the blue shaded area, so no, it's not a solution. (TIP: Solution is the Shaded Area)
If the given figure is rotated 180° around the origin? What are the new coordinates of point Z?
Answer:
(a,b) to (-a,-b)
Step-by-step explanation:
You can think of this as folding the paper horizontly and vertically, and see where the new point lies. You see that the x coordinate changes its sign when the paper folds vertically, and the y coordinate changes its sign when folded horizontally.
But in general, if you have point (a,b) and if you rotate it 180 degrees, you just switch the signs, and you will get (-a,-b).
Ex. (-6,5) rotates 180 degrees and becomes (6,-5)
Answer:
(6,-5)

A man is walking 3 miles per hour toward point B
from point A. At the same time, a woman is
running 6 miles per hour toward point A from
point B. If point A and point B are 15 miles apart,
how far from point B will they meet?
E. 5 miles
F. 6 miles
G. 9 miles
H. 10 miles
PLEASE PLEASE HELP I NEED THIS ANSWER
Answer:
6 miles
Step-by-step explanation:
because the common denominator is 12 so the man will walk 12 miles in 4 hours and the woman will walk 12 miles in 2 hours so they will meet in the middle
If point A and point B are 15 miles apart, they will meet H) 10 miles from point B.
The answer to the question is H: 10 miles.
To solve this problem, we can use the concept of relative velocity. Relative velocity is the velocity of one object as seen by another object. In this case, the man and the woman are moving towards each other, so their relative velocity is the sum of their individual velocities.
The man's velocity is 3 miles per hour and the woman's velocity is 6 miles per hour, so their relative velocity is 3 + 6 = 9 miles per hour.
We know that point A and point B are 15 miles apart, so they will meet when the distance between them is 0. The time it takes them to meet is 15 / 9 = 5/3 hours.
In 5/3 hours, the man will travel 3 * 5/3 = 5 miles and the woman will travel 6 * 5/3 = 10 miles. Therefore, they will meet 10 miles from point B.

Which of the following statements would best represent the value of a? PLEASE HELP
Answer:
The statement would best represent the value of a is a = [tex]\frac{6}{tan(38)}[/tex] ⇒ c
Step-by-step explanation:
In the right angle triangle, we can use the trigonometry ratios to find the missing sides or angles
sin β = [tex]\frac{opposite}{hypotenuse}[/tex]cos β = [tex]\frac{adjacent}{hypotenuse}[/tex]tan β = [tex]\frac{opposite}{adjacent}[/tex]In the given right triangle
∵ There measure of an acute angle is 38°
∵ The adjacent side to this angle is a
∵ The opposite side to this angle is 6
→ We will use the tangent ratio because we have the opposite and
adjacent sides of the given angle
∴ tan(38°) = [tex]\frac{6}{a}[/tex]
→ Multiply both sides by a to cancel the denominator in the right side
∴ a · tan(38°) = 6
→ Divide both sides by tan(38°) to find a
∴ a = [tex]\frac{6}{tan(38)}[/tex]
∴ The statement would best represent the value of a is a = [tex]\frac{6}{tan(38)}[/tex]
