Answer:
101
Step-by-step explanation:
3^4 = 3 * 3 * 3 * 3 = 81
4 ⋅ 5 = 4 * 5 = 20
3^4 + 4 ⋅ 5
= 81 + 20
= 101
Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought 3 magazines, how many books did he buy?
The equation that models the problem is 3.95m + 8.95b = 47.65, where m is the number of magazines and b is the number of books.
__ books
Answer:
4 books
Step-by-step explanation:
Our problem here is:
[tex](3.95)3+8.95b=47.65[/tex]
So we have to find B, and that will be our answer (the number of books).
1. Simplify the expression
[tex]3.95\cdot 3+8.95x=47.65[/tex]
Combine like terms:
[tex]11.85+8.95x=47.65[/tex]
2. Group all constants on the right side of the equation
[tex]11.85+8.95x=47.65[/tex]
Subtract from both sides:
[tex]11.85+8.95x-11.85=47.65-11.85[/tex]
Group like terms:
[tex]8.95x+11.85-11.85=47.65-11.85[/tex]
Simplify the arithmetic:
[tex]8.95x=47.65-11.85[/tex]
Simplify the arithmetic:
[tex]8.95x=35.8[/tex]
3. Isolate the x
[tex]8.95x=35.8[/tex]
Divide both sides by 8.95:
[tex]\frac{8.95x}{8.95}=\frac{35.8}{8.95}[/tex]
Simplify the arithmetic:
[tex]x=\frac{35.8}{8.95}[/tex]
Simplify the arithmetic:
[tex]x=4[/tex]

Answer:
1,256 dm^2 and 400π dm^2
Step-by-step explanation:
The circumference is equal to 2pi times the radius. So 40pi=2pi times the radius so the radius is 20. The area of a circle is pi times the radius squared or 400pi and if using 3.14 for pi this would be 1,256 dm^2

Answer the following sections on parallels lines
Answer:
Parallel lines are lines that never meet and are always the same distance apart. Lines X, Y, and Z are all parallel to each other.
Step-by-step explanation:
in the graph △pqr ≅ △ xyz
Answer:
The answer would be C.
Step-by-step explanation:
We can tell that it has been translated, meaning that the answer will either be C or D. A reflection across the x axis would already reflect PQR six units left, meaning the answer would be C. Sorry for the bad explanation I'm really tired, I hope this helps! :)
Monica has walked 3/2 miles in 2/3 of an hour. How many miles can Monica walk in one hour?
Answer:
2.25 Miles is how many miles Monica can walk in one hour.
Step-by-step explanation:
You take 3/2 which is 1.5 in decimal form then take the 2 out of 2/3 divide 1.5 by 2, you get 0.75 then you add 0.75 to 1.5 and you get 2.25 which is how many miles she walks in one hour.
Help. Where do I put the dot, should it be opened or closed, and what direction should the line face?
Answer: 5 with an open circle facing the right.
Step-by-step explanation:
First: you need to know the difference between closed and open circles. Closed means less than or equal to/ greater than or equal to while an open circle just means less than/ greater than.
Second: To know if it will be facing left or right is very simple. It is just if the number is increasing or decreasing in your problem. If increasing it goes right if decreasing it goes left. In this case, the number increases each day so it will face the right.
Third: To start the problem you subtract the number of shells she has already (34) by how many she needs (100) which is 66. then divide 66 by the number of seashells they get a day (12) which would give you 5.5
Fourth: I'm going to guess that you can't do decimals on the graph so all you have to do is put an open circle with the arrow facing the right meaning everything after this point, not including the number it is on.
Answer:
d ≥ 7
Step-by-step explanation:
A closed dot means you CAN use the number in the equality (greater than and equal to or less than and equal to). An OPEN dot means it's just greater than or less than, no equal to. Positive numbers GROW to the right so if the line is going that way it means greater than or greater than and equal to. The same is true for the left side. The left side makes numbers get SMALLER which means less than or less than and equal to. Your problem has a closed dot and an arrow to the right so the inequality is d ≥ 7.
Show how to use substitution to solve the following system of equations. Write the solution as an ordered pair.
4x - y = 10
y = 2x - 2
*Hint: Substitute 2x-2 for ‘y’ in the first equation: 4x - (2x - 2)= 10
Then solve for ‘x’. Use your answer for 'x' to solve for 'y'.
Include in Your Answer:
The work used to solve for 'x'.
The work used to solve for 'y'.
Your final answer written as an ordered pair (x , y)
Answer:
(6, 10)
Step-by-step explanation:
Step 1: Substitute 2x-2 for ‘y’ in the first equation:
4x - (2x - 2)= 10
Step 2: Combine like terms
2x -2 =10
Step 3: Add 2 to both sides of the equation
2x = 12
Step 4: Divide both sides by 2
x= 6
Now substitute x=6 into any of the equations given, I chose the bottom one.
Step 5: Plug in x=6 and solve
y= 2(6) -2
y= 12-2
y= 10
Step 6: Write your answer as an ordered pair (x, y).

On a piece of paper, use a protractor to construct a triangle with angle measures of 40° and 70°.
Which statements about this triangle are true?
Select all correct answers.
All sides have different lengths.
It is an acute triangle.
It is an obtuse triangle.
The third angle measures 110°.
The third angle measures 70°.
Two sides have the same length.
Answer:
It is an acute triangle.
Two sides have the same length.
The third angle measures 70°.
Step-by-step explanation:
It is an acute triangle because all triangles are less than 90°.
Two sides have the same length because since we know that two angles, which would be the base angles are the same, then triangle must be isosceles.
180°-(40°+70°)= 110°
Calculating Perimeter
Answer: P= 2640 dam
or 264 hm
or 26.4 km
Step-by-step explanation:
See picture of all side values in the three measurement forms
Answer: I think this is right but I'm not 100 percent sure
26.4 km, 264 hm, 2640 dam
Step-by-step explanation:
Well, permitter is adding all lengths together.
Which is 5 km + 62 hm + 62 hm + 900 dm
Assuming hm stands for Hectometer, I will divide 62/10 = 6.2
Now we are left with the equation 5 km + 6.2 km + 6.2 km + 900 dam
Since 100 dm = 1 km, we will divide 900 dm by 100 which is 9 km
Lastly, we are left of with:
5 + 6.2 + 6.2 + 9 = 26.4 km
Now I will quickly covert everything into the other 2 measurements
26.4 km = 264 hm (10x)
26.4 km = 2640 dam (100x)

Noa drove from the Dead Sea up to Jerusalem. When she arrived in Jerusalem after 1.5, points, and 5 hours of driving, her altitude was 710 meters above sea level. Her altitude increased at a constant rate of 740 meters per hour.
y= ???
(this is Writing linear equations word problems)
correct answer gets brainly
Answer:
-400 meters below sea level
Step-by-step explanation:
740(1.5) +y=710
740 (1.5)+ 710
1010 + y =710
y= 710 -1110
so y is -400

Answer: 108 ft³
Step-by-step explanation:
V= 4/3πr³
Facts:
Pi= 3
Diameter = 6
Step1; find the radius
Diameter is the length acaross the whole circle, but the radius is just 1/2 the circle. Therefore, if the diameter is 6, then the radius can be found by finding 1/2 of 6.
1/2 of 6= 1/2x6= 3.
R= 3
Step 2: Plug in the numbers (into the formula)
PEMDAS
(exponents go first)
(then multiply from left to right)
V= 4/3πr³
V= 4/3x3x3³
V= 4/3x3x (3x3x3)
V= 4/3x3x27
V= (4/3x3) x 27
V= 12/3x27
V= 4x27
V= 108
Volume= 108 ft³
Hope this helps :)) Also brainliest would be appreciated, i worked pretty hard on this thanks! :)

Answer: it's wrong
Step-by-step explanation: because there are 6 sides of a die, so there is a 1/6 chance of getting any number between 1 and 6.
reason: this'll help you know how to turn it into a fraction.
Chosen possibility of an action
over (or fraction bar)
total amount of possibilities
so now that you know why, now we find out the possibilities of rolling an odd and even numbers between 1 and 6.
1, 3, 5 = 3/6 = 1/2
2, 4, 6 = 3/6 = 1/2
which means there is 1/2 chance of getting either an even or an odd. so they are incorrect because they are as likely as to not likely to be rolled on.
Answer: they are wrong
Step-by-step explanation: there is 6 sides of a die, so there is a 1/6 percent chance and number between 1 and 6
1, 3, 5 = 3/6 = 1/2 = 50%
2, 4, 6 = 3/6 = 1/2+= 50%

Answer:
Step-by-step explanation:
Because the length width and height of the inch cube are all the same, 1/2 plus 1/2 is 1 so 8 cubes 2 for the length, height and width
as for the cubes volume, 1/2* 1/2* 1/2 = 1/8^3
amd the last ones u solve with the answers to the first 2,
8 Cubes * 1/8^3 = 1inch^3
