Answer:
Step 4.
Step-by-step explanation:
Given that Kayla uses mental math to find the product of $ 11.97x5, but she made a mistake, and knowing that her steps were the following:
Step 1: Round $ 11.97 to $ 12.
Step 2: multiply $ 12.00x $ 5 = 60
Step 3: subtract $ 12.00- $ 11.97
Step 4: subtract $ 60.00- $ 3.00 = 57.00.
To determine in which one is where Kayla made her first mistake, the following reasoning must be performed:
Rounding from 11.97 to 12 implies a difference of 0.03 that must be multiplied by 5, the result of which is 0.15.
Thus, from the result of 12 x 5 (60), 0.15 must be subtracted, and not 3, as was subtracted in Step 4. Therefore, Step 4 is the one where the error occurred.
On a map, 1 inch equals 15 miles. Two cities are 3 inches apart on the map. What is the actual distance between the cities?

Answer: 120ft
Step-by-step explanation:
To work out the area of this composite shape you would have to work out the two shapes separately. The shape could be split into 2 rectangles.
The formula for the area of a rectangle is base x height.
So, to work out the area of the living room you have to do 15x7=105
Then to work out the area of the foyer, you would have to do 3x5=15
Because you want the area of both of the shapes together, you have to add the two areas of the rectangles together.
So 105+15=120
Given circle B below, find the value of x.
(3x + 10)
(2x - 17)
Answer: 44
Step-by-step explanation:
since the inscribed angle is half of true arc measure, (3x+10)= 2(2x-17).
when you work this out, you get 44 as x.
The value of x from the given figure is 44°. Therefore, option B is the correct answer.
What is relation between angle at the center and the angle at the circumference?The angle subtended by an arc at the center is twice the angle subtended at the circumference . More simply, the angle at the center is double the angle at the circumference.
From the given figure,
Angle at circumference is (2x-17)° and angle at center is (3x+10)°.
Now, (3x+10)°=2(2x-17)°
3x+10=4x-34
4x-3x=10+34
x=44°
Therefore, option B is the correct answer.

which expression has the least value when x=100?
A.1/x
b.10/x
c.1-x
D 10-x
Answer:
C
Step-by-step explanation:
C will have the least value with -99.
A would be 1/100, which is 0.01, which is small, but larger than -99.
B would be 10/100, which is 0.1, which is larger than A.
C is 1-100, which equals -99.
D is 10-100, which equals -90. -99 is smaller than -90.
Answer:
c) 1 - x
Step-by-step explanation:
x = 100
a) [tex]\frac{1}{x}[/tex] ⇒ [tex]\frac{1}{100}[/tex]
answer ⇒ 0.01
b) [tex]\frac{10}{x}[/tex] ⇒ [tex]\frac{10}{100}[/tex]

At a sale, suits were sold for $72 each. This price was 45% of a suit's original price. How much did a suit originally cost?
Answer:
$160
Step-by-step explanation:
Let the original cost of suit be x
If the suits were sold for $72 each and this price was 45% of a suit's original price, then;
72 = 45% of x
72 = 0.45x
x = 72/0.45
x = 160
Hence the original price of the suit is $160

The measurement 345.58 cm² is the closest to the total surface area of the can in square centimeters.
The correct option is A.
What is a cylinder?A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.
Given:
A can in the shape of a cylinder has a diameter of 10 centimeters and a height of 6 centimeters.
The surface area of the cylinder,
= 2π r h + 2π r²
= 2 (3.14)(5)(6) + 2 (3.14) (25)
= 345.4 square centimeters.
Therefore, 345.58 cm² is the closest value.

Beginning with the equation 2x + 8y = 12, write an additional equation that would create:
a system with no solutions
Answer:
[see below]
Step-by-step explanation:
A system of equations with no solution would show parallel lines. We just have make a equation that is parallel to the original equation.
The slope of 2x + 8y = 12 is [tex]-\frac{1}{4}[/tex], and it's y-intercept is [tex]\frac{3}{2}[/tex].
Since parallel lines have the same slope but not the same y-intercept, I would use [tex]y=-\frac{1}{4}x+3[/tex].
Any equation that has -1/4 as the slope would work.
When graphed together, they show as a system with no solution.

Answer/Step-by-step explanation:
An expression is a series of number without any signs so expression would be the first one.
Inequality would be when they do a sign like > or <, etc. so it would be the 2nd one.
Equation would be when they have an equal sign which would be the 3rd one.

If there are 1,000 m in 1 km, we can find the number of meters she hiked by multiplying 13 by 1,000:
13(1000)
= 13,000
So, Belle hiked 13,000 meters.

Inequalities help us to compare two unequal expressions. The set of values makes the inequality n > -5 true is {-5, -4.5, -3}.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
As we need to find the values that will satisfy the inequality n≥-5, therefore, we need values that are greater than or equal to -5.
Hence, the set of values makes the inequality n > -5 true is {-5, -4.5, -3}.
