Which is the most reasonable way to estimate 26% of 88?
One-fifth(90)
One-fifth(80)
One-fourth(90)
One-fourth(80)
Answer:
1/4(90)
Step-by-step explanation:
The most reasonable way to estimate 26% of 88 is one-fourth of 90. Therefore, the correct option is C.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, 26% of 88.
Now, 26/100 ×88
= 0.26×88
= 22.88
A) 1/5 ×90
= 18
B) 1/5 ×80
= 16
C) 1/4 ×90
= 22.5
D) 1/4 ×80
= 20
Therefore, option C is the correct answer.

please hurry!! the graph of y= 2/x - 1 is shown which statement about the graph is accurate
A. the x-intercept or the graph (2, 1)
B. the graph has no y-intercepts
C. the y-intercept of the graph is (2, 0)
D. the graph has no x-intercepts
Answer:
B. The graph has no y-intercepts
Step-by-step explanation:
We see that we have vertical and horizontal asymptotes.
We also see that the right side of the graph has an x-intercept of (2, 0).
Therefore, A and D are incorrect.
We use the vertical asymptote x = 0 to get our answer B, as we will never cross the y-axis as x approaches negative and positive infinity.

Karina and Perry are cleaning up litter in the park for community service hours. Karina and Perry both claim they have covered the greatest area. Who is correct? Justify your answer using mathematical reasoning.
Answer:
Perry is correct, she covered the greatest area = 18 square units.
Step-by-step explanation:
Looking at the attached diagram, the shapes are rectangular and they are on grid or graph
Note that on a graph:
1 square box = 1 unit
Area of rectangle = Length × Width
For Karina
The Width = 3 units
The length = 4 units
The area which Karina covered = 3 units × 5 units
= 15 square units
For Perry
The Width = 9 units
The length = 2 units
The area perry covered = 9 units × 2 units
= 18 square units
Therefore, Perry is correct, she covered the greatest area = 18 square units.
A square has a perimeter of 28 ft. What is the length of each side? and it is in ft

If a car is traveling at 50kph, how long would it take for the car to travel 12.5km?
Answer:
4 km
Step-by-step explanation:
T = time
D = distance
S = speed
the forumla to find the distance is
T * S = D
manipulate the equation for this problem:
D/S = T
Plug-in the known values
D = 12.5 km
S = 50kph
12.5km/50kph
cancel units and simplify
4 km

In the following equations, let x =-3 and y = 2/3. Determine whether the following equations are true or false, or neither true or false.
A. xy = -2
B. x + 3y = -1
C. x + z = 4
D. 9y = -2x
E. y/x = -2
F. -2/x / y = -1
xy = -2
(-3)(2/3) = -2
-2 = -2 TRUE
x + 3y = -1
-3 + 3(2/3) = -1
-3 + 2 = -1
-1 = -1 TRUE
x + z = 4
-3 + z = 4
z = 7 NEITHER
9y = -2x
9(2/3) = -2(-3)
6 = 6 TRUE
y/x = -2
(2/3)/(-3) = -2
-0.22... = -2 FALSE
-2/x / y = -1
-2/-3 / 2/3 = -1
2/3 / 2/3 = -1
1 = -1 FALSE
Best of Luck!
Answer:
A. xy = -2 - true
B. x + 3y = -1 - false doesn't equal -1 it equals -2
C. x + z = 4 - neither because z
D. 9y = -2x - false because it equals -6
E. y/x = -2 - false because it equals -.2222222

Which of the equations below is the simplified version of 3[2 - 2(3x + 1)] = 4(3x - 5)
Answer:
option 4) -18x = 12x-20
Step-by-step explanation:
3[2-2(3x+1)] = 4(3x-5)3[2-6x-2] = 12x - 203[-6x] = 12x - 20-18x = 12x-20Aaron wants to make as many gluten-free, low-carb cupcakes as he can for a bake sale. His recipe for 12 such cupcakes requires ⅜ of a cup of cocoa. Assuming Aaron has enough of the remaining ingredients, which of the following is closest to the number of cupcakes that he could make if he has 2 cups of cocoa? A)10 B)30 C)60 D)100
Answer:
I believe it is C
Step-by-step explanation:
First, I decided to use the proportion method. (Before I use this method, let's change [tex]\frac{3}{8}[/tex] into a decimal. So, that will be 0.375.
We know that we can cross multiply in a proportion
[tex]\frac{0.375 cups}{12 cupcakes} = \frac{2cups}{x}[/tex]
0.375x = 24
x = 64
round to tens
60
The number of cupcakes that he could make if he has 2 cups of cocoa is C) 60.
What is proportion?A proportion is an equation in which two ratios are set equal to each other.
Now, it is given that,
12 such cupcakes requires ⅜ of a cup of cocoa
So ratio, cup of cocoa : cupcakes = ⅜ : 12
⇒ cup of cocoa / cupcakes = ⅜ / 12
Now, let x be the number of cupcakes that he could make if he has 2 cups of cocoa
So ratio,cups of cocoa : number of cupcakes = 2 : x
Hence,By proportionality we get,
cup of cocoa : cupcakes = cup of cocoa : cupcakes
⅜ : 12 = 2 : x
⅜ / 12 = 2 / x
⇒ 0.375/12 = 2 / x
⇒ x = (2x12)/0.375
⇒ x = 24/0.375
⇒ x = 64
hence it is closest to the number 60.
So,The number of cupcakes that he could make if he has 2 cups of cocoa is C) 60.
