Niles and Bob sailed at the same time for the same length of time. Niles' sailboat traveled 30 miles at a speed of 6 mph, while Bob's motorboat traveled 70 miles at a speed of 14 mph. For how long were Niles and Bob traveling?
Answer: 5 hours
Step-by-step explanation:
As both of them sailed for the same time, take the speed and distance of either of them to find the time they traveled:
Niles' Time = Distance / speed
= 30 / 6
= 5 hours
Bob's time = 70 / 14
= 5 hours
Mr. Arnold is buying dry-erase markers for his classroom. He already has 7 markers. Mr. Arnold buys 5 packs with 7 markers each and 8 packs with 4 markers each. He then throws away 2 markers that do not work. Which number sentence best represents how many dry-erase markers Mr. Arnold now has in his classroom?

Which equation models this situation?
25 more than a number is 32.
O A. x+ 25 = 32
B. x + 32 = 25
O C. x - 25 = 32
D. x = 25 + 32
Angle B and angle C are complementary. If angle B is five times the size of angle C what is the measurements of both angles.
Step-by-step explanation:
Let Angle C be x
So angle B will be 5x
Since they both are complementary, we can come up with this equation.
x+5x=90 degrees
6x=90 degrees
x=90/6,x=15
Measures of Angles
Angle C=x=15 degrees
Angle B=5x=5*15=75 degrees

determine the range of the following graph
Given:
The graph of a function is given.
To find:
The range of the graph.
Solution:
We know that, the domain is the set of input values and range is the set of output values.
In a graph, domain is represented by the x-axis and range is represented by the y-axis.
From the given graph it is clear that there is an open circle at (-8,-8) and a closed circle at (3,4). It means the function is not defined at (-8,-8) but defined for (3,4).
The graph of the function is defined over the interval [tex]-8<x\leq 3[/tex]. So, the domain is (-8,3].
The values of the function lie in the interval [tex]-8<y\leq 4[/tex]. So, the range is (-8,4].
Therefore, the range of the function are all real values over the interval (-8,4].
Find the measure of the missing angle *
Answer:
21°
Step-by-step explanation:
we know that every single triangle has to equal 180°
we have all 3 angles 90° 34° 35° which equal 159°
so we take 180°-159° and your answer is 21°

Step-by-step explanation:
[tex]x^\frac{1}{y}=\sqrt[y]{x}[/tex]
So:

Answer:
A=4
Step-by-step explanation:
Area of rhombus=[tex]\frac{d1+d2}{2}[/tex]
d1=BD=4
d2=AC=2
so [tex]\frac{4*2}{2}=4[/tex]
area of quadrilateral (rhombus)=4square units
:
Solution given:
diagonal 1:AC=2 unit
diagonal 2:BD=4 unit
it looks like a rhombus
so
area of quadrilateral (rhombus)
=½*(diagonal 1*diagonal2)=½(2*4)=4 square units
please help me ill mark you brainlyest
Answer:
A is false it said it could be greater than 35 or equal to and 100 x 5 = 500 + 1 = 501 therefore a is false
B is false 6.8 could be possible and it could be a decimal it can't only be a whole number
C is false 6 4/5 is a solution so c is false
D is I'm not sure, I think infinite except for 7 and below so maybe true
E is false because any number greater than 7 that are multiplied to 5 can be as long as its greater than or equal to 35
Ok this is what I think. Id rather wait for more answers to be sure thank you.

Themla spent 1/6 of her weekly allowance on dog toys. 1/4 on a dog collar, and 1/3 on dog food. What fraction of her weekly allowance is left?
Answer:
¼ remaining
Step-by-step explanation:
Convert to common numerator of 12:
1/6 = 2/12
1/4 = 3/12
1/3 = 4/12
Total: 9/12
1 - 9/12 = 3/12 = ¼

WILL GIVE BRAINLIEST IF YOU USE LAW OF SINES CORRECTLY
Please solve using the law of sines.
Answer: I know this is an old question, but in case you still don't know how to do Law of Sine here's how you would have solved it. (P.S. I wasn't sure which part of the triangle the problem was looking for, so I solved for all parts)
Step-by-step explanation:
Answer:
[tex]\displaystyle 7,7[/tex]
Step-by-step explanation:
Use the Law of Sines to find the length of the second edge:
Solving for Angles
[tex]\displaystyle \frac{sin\angle{C}}{c} = \frac{sin\angle{B}}{b} = \frac{sin\angle{A}}{a}[/tex]
Use [tex]\displaystyle sin^{-1}[/tex]towards the end or you will throw your result off!
Solving for Edges
[tex]\displaystyle \frac{c}{sin\angle{C}} = \frac{b}{sin\angle{B}} = \frac{a}{sin\angle{A}}[/tex]
Let us get to wourk:
[tex]\displaystyle \frac{c}{sin\:44} = \frac{11}{sin\:82} \hookrightarrow \frac{11sin\:44}{sin\:82} = c; 7,7163369357... \\ \\ \boxed{7,7 \approx c}[/tex]

Central Fencing has been hired to fence the perimeter of a rectangular field. The length of the field is 42 - W feet, where W is the width of the field, and the area of the field must be more than 432 square feet. Find the bounds on the width of the field.
Answer:
10.3 is the width
Step-by-step explanation:
set up an equation
42w=432
divided both sides by 42
W=10.2857142857
to rounded it to nearest tenth it will be 10.3
to check your answer multiply 10.3 by 42 it will be 432
check check
Answer:
18 ≤ w ≤ 24
Step-by-step explanation:
A = l * w
A ≥ 432 sq ft.
l = 42 - w
432 ≤ (42 - w) (w)
432 ≤ -w² + 42w
w² - 42w ≥ 432
Substitute values for w
w = 18
w = 24

Answer:
64
Step-by-step explanation:
It is hard to explain in writing. Because all of the sides are semetrical then whatever mesurment that is on one side, will be on the other. So for example, if there is 12in on one side, the other side will be 12in too. If the top of the letter is 3in, then so are the rest of the parts that are the same size. When you figure out all of the lengths of the sides then you add them up.
I hope this helps.
If it didn't then plz tell me what I need to clarify :)

X = ?
Answer:
x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
[tex]\frac{1}{2}[/tex] (3x + 3 + 4x + 2) = 13
[tex]\frac{1}{2}[/tex] (7x + 5) = 13 ( multiply both sides by 2 )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
