Answer:
Number of minutes in [tex](5\times \frac{1}{10})[/tex] hours = 30 minutes
Step-by-step explanation:
Number of minutes in 1 hour = 60 minutes
Number of minutes in [tex]\frac{1}{10}[/tex] hours = [tex]\frac{60}{10}[/tex] minutes
= 6 minutes
Therefore, number of minutes in [tex]5\times \frac{1}{10}[/tex] hours = 5 × 6
= 30 minutes
Ms. Benson is making a jewelry box using 2 identical squares of wood and 4 identical rectangular pieces of wood, as shown below.
What is the surface area of the jewelry box in square inches (sq. in)?
Length of rectangles = 7 in.
Breadth of 4 rectangles = 3 x 4
= 12 in.
Side of squares = 3 in.
Area of 4 rectangles = length x breadth
= 7 x 12
= 84 sq. in.
Area of two squares = 2(side x side)
= 2(3 x 3)
= 18 sq. in.
Therefore, Surface area of the Jewellery box = 84 sq. in. + 18 sq. in.
= 102 sq. in.
You want to buy 7 tickets at that same rate. Explain the mathematical process you used to determine the cost of 7 tickets. (Include the unit rate in your explanation)
Answer:
7x
Step-by-step explanation:
To purchase 7 tickets at the same rate ;
Mathematically, Total Cost of an item is :
Cost = unit price * quantity
Here,
quantity = 7 tickets
Since price per ticket(rate) is the same ; then we can take rate as x
Hence, the cost of the 7 tickets is :
Quantity * rate
7 * x = 7x
A python snake on display at a pet store is 62 centimeters long. About how many inches long is the snake? Using
complete sentences, explain how you would convert from cm to inches.

Determine the slope of the line that passes through the points
(4, 4) and (5,0).
Answer:
B) -1/2
Step-by-step explanation:
Slope is change in y divided by change in x.
So, 6-4/-4-0 = 2/-4 so reduces to -1/2
Answer:
Slope = -4
Step-by-step explanation:
Slope = change in y ÷ Change in x
[tex]= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\= \frac{0-4}{5-4}\\\\= \frac{-4}{1}\\\\= - 4[/tex]

Hi, I am very stuck on questions 17 and 18. Can someone help please? Thanks

Answer:
17) x = 10√2
18) x = 4√6
Step-by-step explanation:
These problems rely on your knowledge of the side ratios of special triangles
45°-45°-90° triangle: 1 : 1 : √2
30°-60°-90° triangle: 1 : √3 : 2
__
17) 5 is the short side of the isosceles right triangle, so its hypotenuse is 5√2. That length is the shortest side of the 30/60/90 triangle, so its longest side is 2 times that:
x = 10√2
__
18) 8 is the longest side of the 30/60/90 triangle, so its long leg will be 8(√3)/2 = 4√3. The hypotenuse of the isosceles right triangle is √2 times that, so ...
x = (4√3)(√2)
x = 4√6
A local shelter is having an Adopt-a-thon for kittens and puppies. Kittens cost $50 to adopt and puppies are $75. The shelter made $1200 during the Adopt-a-thon event and adopted off twice as many puppies as kittens. Write and solve a system to find how many puppies and kittens were adopted
Answer:
Step-by-step explanation:
P=2K
50K+75P=1200, using P from above makes this equation become
50K+75(2K)=1200
50K+150K=1200
200K=1200
K=6, since P=2K
P=2(6)=12
So 12 puppies and 6 kittens were adopted.

Help me with this pls
Answer:
C
Step-by-step explanation:
I have to study for a test. It's for data management. Does anyone have tips? (Grade 7)
Studying: Use resources.
If your studying for a test, use some resources, like quizizz, quizlet, flashcards, or the internet. If you do, ask your parents for help. Think it like its your big test, and your studying a lot. If you study and try, you'll pass the test on data management. If you need it, ask your teacher for tutoring or practice some data management questions. Studying will help you not to fail a test.
Now, we'll talk about before the test.
Before test: Rest, eat breakfast, and stay calm.
Step-by-step explanation: Going to bed before a test can prevent you from going to sleep. For example, GMAS (for me) is coming soon, and my teacher encourage us to rest, eat breakfast and stay calm. A recommended time for you to go to bed is 8:00-9:30.
Now, about breakfast.
Eating breakfast is also important because you can perform better, in fact, scientists say that if students eat breakfast before a test or exam, they will perform better! Whatever you do, don't skip breakfast. If you do, you won't perform good, and theirs a chance you could fail.
Now, staying calm is the big one.
If your freaking out, stay calm, say a prayer and get your work done! Staying calm is the big one because most students (I am one of them) get worried if they're gonna fail. Keep this in mind: Try. Your. Best. If you don't try, you won't achieve anything. And please don't cheat. If you cheat, you'll have to repeat the whole grade. Can't cheat in college; you'll get kicked out.
During test: DO. NOT. CHEAT.
CHEATING WILL GET YOU KICKED OUT OF COLLEGE AND YOU'LL AUTOMATICALLY FAIL!!! If your computer prevents you from going to other sites, that is good, but don't pull out ANY study guides or notes during your test, unless it's open-notes. If you don't know a questions, skip it and go to the next one. Then go back, it will come to mind later. If your done with your test early, check your answers. Look back and think, "Is this correct?"
Hope you do good on your test!

Find the value of the lettered angles in each of the following ( see image ).
Please show workings.
The only given angles are 60° , 10° , 40°
Answer:
Step-by-step explanation:
s + 40 + 60 = 180 {angle sum property}
s + 100 = 180
s = 180 - 100
s = 80
This figure is a cyclic quadrilateral. sum of opposite angles are 180
s + v + 60 + 10 = 180
80 + v + 60 + 10 = 180
v + 150 = 180
v = 180 - 150
v = 30
y+ 10 + v = 180 {angle sum property}
y + 10 + 30 = 180
y + 40 = 180
y = 180 - 40
y = 140
9514 1404 393
Answer:
r = 80°, s = 80°, t = 10°, u = 60°, v = 30°
Step-by-step explanation:
Working clockwise from the left side, we can name the points on the circle as A, B, C, D. The given inscribed angles are half the measure of the arcs they intercept, so we have ...
arc BD = 2×40° = 80°
arc DA = 2×60° = 120°
arc CD = 2×10° = 20°
From these measures, we can deduce the measures of the individual arcs as ...
arc AB = 360° -BD -DA = 360° -80° -120° = 160°
arc BC = BD -CD = 80° -20° = 60°
Then the angle measures of interest are ...
r = AB/2 = 80°
s = AB/2 = 80°
t = CD/2 = 10°
u = DA/2 = 60°
v = BC/2 = 30°

2. Scientists measure a bacteria population and find that it is 20,000. Four days
later, they find that the population has doubled. Which function f could describe
the bacteria population d days after the scientists first measured it, assuming it
grows exponentially?
Answer:
P(t) = 20,000 * e^0.173287t
Step-by-step explanation:
P(t) = Po * e^k*t
Po = 20,000
t = 4
P(t) = 40,000
40,000 = 20,000 * e^4k
2 = e^4k
ln 2 = ln e^4k
ln 2 = 4k * ln e
ln 2 = 4k
0.173287 = k
The shorter leg of a right triangle is two less than the hypotenuse. The longer leg is one less than the hypotenuse. Find all three sides of the triangle. HELP TEST!
Answer:
x = 5
Step-by-step explanation:
using the Pythagorean theorem:
(x-1)² + (x-2)² = x²
x²-2x+1 + x²-4x+4 = x²
reduce:
2x²-6x+5 = x²
subtract x² from each side:
x²-6x+5 = 0
(x-1)(x-5) = 0
x=1 but because shorter leg would be 0, a triangle would be impossible.
x=5

determine whether the polygon is concave or convex?
Answer: Convex
Step-by-step explanation
The difference between convex and concave polygons lies in the measures of their angles. Another way to think of it is this: the diagonals of a convex polygon will all be in the interior of the polygon, whereas certain diagonals of a concave polygon will lie outside the polygon, on its exterior .Also If the interior angles of of the polygon are less than 180 degrees, then the polygon is convex. But if any one of the interior angles is more than 180 degrees, then the polygon is concave. T∴×∴T that was a lot

Hayden will attend a craft show the cost of admission ticket is eight dollars the cost of a raffle ticket for a handmade quilt available only with those admission ticket is five dollars Hayden has $45 what is the greatest number of raffle tickets he can buy
Answer: 7 tickets
Step-by-step explanation:
First you need to remove the cost of entrance from the $45 that Hayden has:
= 45 - 8
= $37
The $37 is the amount that is left for Hayden to be able to buy tickets for the raffle.
The tickets cost $5 each so the highest number of tickets that can be bought with $37 is:
= 37 / 5
= 7 tickets
