Bobby was painting a sign that was 2 3/4 feet by 1 1/2 feet. Use the model to help find the area of the sign.
What was the area of the sign in square feet?
A. 4 1/4 square feet
B. 4 1/8 square feet
C. 3 1/4 square feet
D. 3 1/8 square feet
Answer:
4 1/8 square feet
Step-by-step explanation:
Area= l*b assuming that it's a rectangle or a square
2 3/4* 1 1/2= to do this we need to convert these mixed fractions to improper fractions (How to convert-Multiply the whole number part by the fraction's denominator. Add that to the numerator. Then write the result on top of the denominator.)
so, 2 3/4 converted will be- 11/4
& 1 1/2 converted will be- 3/2
11/4*3/2=33/8
Now we need to convert this into a mixed fraction again, coz the question was given in that form. (How to convert-Multiply the whole number part by the fraction's denominator. Add that to the numerator Then write the result on top of the denominator.)- so,
The ans would be 4 1/8 sqft
17 times 0.0167. Can someone solve this step by step
Answer:
0.2839
Step-by-step explanation:
Can you tell me what part you are stuck on?
Answer:
0.2839
Step-by-step explanation:
-First, move the decimal over 4 places to the right to make 0.0167 into a whole number, which will turn into 167.
-Now, multiply 17 times 167 to get 2839.
-Finally, since the decimal from 0.0167 was moved 4 places to the right, it needs to be moved back 4 places to the left. Once it was moved back 4 places to the left, the answer should now be 0.2839
Hope this helps! :)

In the figure below, determine the perimeter of triangle EFG
Answer:
82 units
Step-by-step explanation:
From the image, we can see that the 2 triangles are similar triangles.
Thus:
BC = EF
BD = EG
CD = FG
Now, BD = 4x - 9 and EG = 2x + 15
Thus;
4x - 9 = 2x + 15
4x - 2x = 15 + 9
2x = 24
x = 24/2
x = 12
Thus, in triangle EFG where EG = 2x + 15, then EG = 2(12) + 15 = 39
Also, EF = BC = 17
FG = 26
Thus, perimeter of triangle EFG is;
P = 26 + 17 + 39
P = 82 units
Find the unit rate: 180 miles in 3 hours
Answer:
60/1 or 60
Step-by-step explanation:
Divide 180 by 3
60
So the unit rate is 60/1
Answer:
60 miles per hour
Step-by-step explanation:
The unit rate is the number of miles traveled per hour. To solve this divide the total miles traveled by number of hours, 180/3. The quotient is 60.

Professor Walter precisa pintar uma quadra, que tem o formato retangular, cujo comprimento é de 45 m por 38 m. Para isso ele vai comprar baldes de tinta em uma loja de construção. Sabendo que com cada balde de tinta ele conseguirá pintar 72 m² de piso, quantos baldes de tinta ele precisará comprar
Answer:
24 buckets
Step-by-step explanation:
Given that :
Dimension of rectangular block = 45 m by 38 m
A bucket of paint will cover 72m² of floor
Total area of floor : Length * Width
Total Area = (45m * 38m) = 1710 m²
Buckets of paint required :
Total area / Area per bucket
= 1710m² / 72m²
= 23.75 buckets
= 24 buckets

Step-by-step explanation:
A baseball is thrown in parabolic arc its position above the ground at a given point in time can be represented by a quadratic function p(t)= 1/2gt^2 + v0t +p0 where t > 0, g is -32ft/sec/sec, V0 is additionally velocity and P0 SH initial position above the ground. If the ball is thrown straight up 16ft/sec when it was 5ft above the ground how high did it go
Answer:
13 ft.
Step-by-step explanation:
Since p(t)= 1/2gt² + v₀t +p₀ and it us given that v₀ = 16 ft/s, p₀ = 5 ft and g = -32 ft/s².
Since the ball is thrown straight up, it does not follow a parabolic path.
So, If the ball is thrown straight up 16ft/sec when it was 5ft above the ground, then its height above the ground h(t) = v₀t +p₀. Substituting v₀ = 16 ft/s, p₀ = 5 ft , we have
h(t) = v₀t +p₀
Using v = v₀ + at, we calculate the time it takes to reach maximum height. At maximum height, v = 0, so,
v = v₀ + at
v - v₀ = at
t = (v - v₀)/a where a = g
So, t = (0 - 16 ft/s)/-32 ft/s²
= - 16 ft/s/-32 ft/s²
= 1/2 s
= 0.5 s
Substituting t = 0.5 s, v₀ = 16 ft/s and p₀ = 5 ft into h(t), we have
h(t) = v₀t +p₀
h(t) = 16 ft/s × 0.5 s + 5 ft
h(t) = 8 ft + 5 ft
h(t )= 13 ft
The ball will go 13 ft above the ground.
How do I find a table that represents Y as a function of X
Answer:
C: x: 5, 2, 6, 4, 1, 3; y: 2, 2, 2, 2, 2, 2
Step-by-step explanation:
Things that can represent a function of x has to be able to be shown in the form of a function, such as "y =" or "f(x) =". I'm guessing you're learning about linear lines, so I'm going to talk about this with linear lines.
A linear line must be straight and for y to be represented as a function of x, it has to have a constant increase or decrease for every x. Here is how to identify non-function lines:
- If there are different y values for the same x value
- If the points in order do not create a straight line
- If the points in order do not have a repeating pattern
To identify a function, look for:
- Straight lines
- An actual written function (such as "y =" or "f(x) =")
- A pattern on a table
Now, the pattern you're going to be looking for on a linear table is an addition or subtraction one for every x. If the x values are in order, then for every 1 x, there should be a constant addition or subtraction to the y.
Here's an example of a table that represents y as a function of x:
- X: 1 2 3 4 5
- Y: 3 5 7 9 11
- Pattern: +2 y for every x with constant 1
- X: 3 1 5 4 7
- Y: 9 3 15 12 21
- Pattern: +3 y for every x with constant 0
Here's an example of a table that doesn't represent y as a function of x:
- X: 1 2 3 4 5
- Y: 2 5 8 2 4
- Pattern: None
- X: 3 1 5 1 7
- Y: 1 7 8 9 4
- Pattern: None

Answer:
∠2 and ∠5 should not be Alternate exterior angles. ∠2 and ∠11 can be Alternate exterior angles if that is an option. The rest is correct. As for consecutive interior angles, you have (∠3 and ∠9), (∠4 and ∠10), (∠7 and ∠13) and (∠8 and ∠14).
Step-by-step explanation:
Alternate exterior angles are basically like the angles that are the combination of a vertically opposite angle and a corresponding angle. Since the vertical lines are not parallel, ∠2 and ∠5 cannot be Alternate exterior angles.
Consecutive interior angles are any pair of angles that are within a pair of parallel lines and add up to 180°.

The expression x + 0.25x can be used to determine a 25% increase in the number of blog views from last month to this month. What expression shows this another way?
Answer:
1.25x
Step-by-step explanation:
Given that :
25% Increase in number of blog views can be expressed as (x + 0.25x)
Another way to make this representation is :
Total number of blog views + 25% of total
Total should add up to 100%
Let number of views = x
Hence,
(100% + 25%) of x
125% of x
125%x
= 1.25x

What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
If the two chords of the circle intersect at a point, then the product of the segments of the chord will be equal.
We know that the product of (x - 5) & (x - 8) and (x - 5) & (x) will be equal. Then we have
(x - 5) · (x - 8) = (x - 11) · x
Simplify the equation, then the value of the variable x will be
(x - 5) · (x - 8) = (x - 11) · x
x² - 13x + 40 = x² - 11x
2x = 40
x = 20
Thus, the value of the variable x is 20.
Then the correct option is A.
