Answer:
28
Step-by-step explanation:
So I just figured out by counting. The top has 8, which means the bottom also has 8. The sides are 3, 2, 1, 1, 2, 3
The total is 8 + 8 + 3 + 2 + 1 + 1 + 2 + 3 = 28

The area of the rectangle is 20 square inches. The rectangle is enlarged by a factor of 6.
What is the area of the enlarged rectangle?
120 in.²
720 in.²
2,400 in.²
14,400 in.²
Answer:
B
Step-by-step explanation:
Here, we are told that the rectangle is enlarged by a factor of 6, we now want to calculate the new area of the said rectangle.
Now, for the rectangle to have an area of 20, mathematically the area of a triangle can be calculated using the formula L * B
where L is the length and B is the breadth
our product here is 20, so any product that gives 20 would be a good fit as the value of the width and length of the rectangle
So, let’s say the sides measure 5 inches by 4 inches
Enlarging these by a factor of 6, we have 30 inches by 24 inches
The new area of the rectangle would thus be ;
30 inches * 24 inches = 720 inches^2
Answer:
b

Find the surface area of the cylinder. Round to the nearest tenths.
Answer:
The surface area of the cylinder is 251.2cm²
Step-by-step explanation:
To solve this problem we have to calculate the circle area and the lateral area
radius = half of diameter
r = 10/2 = 5cm
To calculate the area of the circle we use the following formula
a = area
r = radius = 5cm
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (5cm)²
a = 3.14 * 25cm²
a = 78.5cm²
The area of the circle is 78.5cm²
To calculate the lateral area of the cylinder we use the following formula
a = area =
h = heighti = 3cm
r = radius = 5cm
π = 3.14
a = 2 * π * r * h
we replace with the known values
a = 2 * 3.14 * 5cm * 3cm
a = 6.28 * 15cm²
a = 94.2cm²
The lateral area of the cylinder is 94.2cm²
Now we add the lateral area of the cylinder with 2 times the area of the circle and obtain the area of the cylinder
94.2cm² + (2 * 78.5cm²) = 251.2cm²
The surface area of the cylinder is 251.2cm²

Check the consistency of 2x-3y=7 and x-2y+1=0
Answer:
x = 17, y = 9
or as an ordered pair, (17, 9).
The equations are consistent.
Step-by-step explanation:
2x - 3y = 7
x - 2y = -1 Multiply this equation by -2:
-2x + 4y = 2 Add this to the first equation:
y = 9.
Plug y = 9 into the second equation:
x - 2*9 = -1
x = -1 + 18 = 17.

(2n + 4) + 6 = –9 + 4(2n + 1)
Answer:
n=2.5
Step-by-step explanation:
(2n+4)+6=-9+4(2n+1)
Expand parentheses:
2n+10=-9+8n+4
Combine like terms:
15=6n
Divide both sides by 6:
n=2.5

Write the coordinates of the image of Q(-3,-6) reflected in the line y=x
HELP PLEASE I RLY NEED HELP URGENT
Answer: (-6, -3)
Step-by-step explanation:
We have the point (-3, -6)
And we want to do a reflection over the line y = x.
When we do a reflection of the point (x, y) over the line y = x. the reflected point will be (y, x)
So if our original point is (-3, -6) then the reflected point is (-6, -3)
Order these fractions from least to greatest 7/8 4/6 3/4
Answer:
4/6 , 3/4, 7/8
Step-by-step explanation:
7/8 4/6 3/4
The common denominator is 24
7/8*3/3 = 21/24
4/6* 4/4 = 16/24
3/4 * 6/6 = 18/24
From smallest to largest
16/24, 18/24, 21/24
4/6 , 3/4, 7/8
Which inverse operations could you use to solve the equation m5−8=−6? Select all that apply.
A
Multiply each side by 5 and then add 8 to each side.
B
Add 8 to each side and then multiply each side by 5.
C
Add 8 to each side and then divide each side by 5.
D
Subtract 8 from each side and then multiply each side by 5.
E
Subtract 6 from each side and then multiply each side by 8.
F
Multiply each side by 5 and then add 40 to each side.
Answer:
Correct option: C
Step-by-step explanation:
To solve the equation m*5 - 8 = -6, we can use the following steps:
step1: sum 8 in both sides, to make m*5 be the only term in the left side.
m*5 = 2
step2: divide both sides by 5, then we will have 'm' isolated in the left side.
m = 2/5
So the operations we could use is: add 8 to each side and then divide each side by 5.
Correct option: C
Berto has $12 and 3.75 per gallon how much gas can he get
Answer:
(3.2, 12)
Step-by-step explanation:
Total cost for gas = $12
Cost per gallon = $3.75
Letting total cost of gas be y and number of gallons be x, maximum number of gallons of gas he can buy would be ;
Total cost of gas/ cost per gallon = 12 / 3.75 = 3.2 gallons
Therefore , the coordinate pair (x, y) = (3.2, 12)

solve for q
Answer: -3
Step-by-step explanation:
-3^2=-3*-3=-9
Because the square of q is equal to -9, the square root of -9 is equal to q.
Because of this fact, we can find the square root of -9 to get our answer.
[tex]\sqrt{-9}[/tex] = 3 i.
Therefore, q is equal to 3 i or [tex]\sqrt{-9}[/tex].

Harpreet took out a payday loan of $500.00. He had to repay $540.00 within 7 days.
A) What was the daily interest on the loan
B) What was the annual interest?
Answer:
a) 1,14%
b) 317%
Step-by-step explanation
J = C . i . t
540 - 500 = 500 . i . 7
40 = 500 . 7 . i
i = 0,0114 = 1,14% within day
-------------------------------------------
J = 500 . 0,0114 . 365 = 2085,71
2085,71 - 500 = 500 . i . 1
1585,71 = 500 . i
i = 3,17 = 317% annual
A plane is descending onto the runway with an angle of depression of 55°. If it has 2.8 miles to go before landing (hypotenuse), what is the current altitude of the plane?
A. 4.9 miles
B. 3.4 miles
C. 4 miles
D. 1.6 miles
E. 2.3 miles
Answer:
Option C is correct
Step-by-step explanation:
Given: A plane is descending onto the runway with an angle of depression of 55°. Also, it has 2.8 miles to go before landing.
To find: current altitude of the plane
Solution:
Consider the attached image.
In ΔABC,
[tex]\angle ACB=55^{\circ}[/tex] (Alternate interior angles)
For any angle [tex]\theta[/tex],
[tex]tan \theta[/tex] = side opposite to angle/side adjacent to angle
[tex]\tan C=\frac{AB}{BC}[/tex]
Put [tex]\angle C=55^{\circ}\,,\,BC=2.8\,\,miles[/tex]
[tex]AB=2.8\,\tan 55^{\circ}=3.999\approx 4\,\,miles[/tex]
So, the current altitude of the plane is 4 miles.
An object is launched directly in the air at a speed of 64 feet per second from a platform located 16 feet in the air. The motion of the object can be modeled using the function f(t)=−16t2+64t+16, where t is the time in seconds and f(t) is the height of the object. When, in seconds, will the object reach its maximum height?
Answer:
Step-by-step explanation:
x= -b/2a = -64/2(-16) = 2
showing that the object will reach its highest point at 2 seconds

4(2x - 3) = 6x + 2

4(2x - 3) = 6x + 2
Expand it:
8x - 12 = 6x + 2
+ 12 to both sides
8x = 6x + 14
- 6x from both sides
2x = 14
Divide both sides by 2:

I Need Help With This Question
Attachment below
Answer & Step-by-step explanation:
For this problem, all we have to do is add f(x) to g(x). So, we will add (x -2) to (x² + x - 6).
(x - 2) + (x² + x - 6)
Combine like terms.
x² + (x + x) + (-2 + (-6))
x² + 2x - 8
So, (f + g)(x) is equal to x² + 2x - 8

Logan is reading about architecture and learns that trusses can be used to support roofs. He wants to find the measures of the angles on a truss. truss.
Answer:
It could help Logan to first study the constitution and shape of this type of armor in order to make a mental image of the positions of the angles as well as the size.
Step-by-step explanation:
A previous study allows Logan to understand that these types of trusses have a triangular shape and are widely used in the construction of roofs, therefore Logan could use to draw this type of trusses.
Find the volume of the cylinder Either enter an exact answer in terms of Pi or use 3.14 or Pi
Answer:
[tex]Volume = 54\,\pi[/tex]
Step-by-step explanation:
Recall the formula for the volume of a cylinder:
[tex]Volume=\pi \,R^2\,H[/tex]
where R is the radius of the cylinder's base, and H is the cylinder's height.
Therefore, in our case the volume becomes:
[tex]Volume=\pi \,R^2\,H\\Volume=\pi \,3^2\,*\,6\\Volume = 54\,\pi[/tex]
A rectangular piece of metal is 25in longer than it is wide . Squares with sides 5in long are cut from the four corners and the flaps are folded upward to form an open box. If the volume of the box is 750in, what were the original dimensions of the piece of metal
Answer:
Step-by-step explanation:
Let width be x
Let lenght be 25 + x
Total ax = (25+x) * x
Square with 5in long are cut from the four corner formed = 750in
(25+x-10) * (x-10) * 5 = 750
(15+x) (x-10) = 150
15x-150+x^2-10x =150
15x -150-150+x^2-10x+0
x^2+15x-300=0
(ax^2+bx+c=0)
