Step-by-step explanation:
In all cases, we represent minutes that Christopher has read with variable x
Christopher has read for more than 32 minutes corresponds with the inequality: x > 32 ."More than" is equivalent to "greater than", which is symbolized by ">".
Christopher has read for less than 32 minutes, corresponds with the inequality: x < 32 . "Less than" symbolized by "<".
Christopher has read for 32 minutes corresponds with the equality: X = 32. Here the amount of time is fixed, so it agrees with an equality instead of an inequality.

Answer:
15.924
Step-by-step explanation:
The difference between these two integers is 15.924.
Given that,
The one integer is 28.935.
And, the other integer is 13.011.
We need to find out the difference between these two integers.
So,
The difference is
= 28.395 - 13.011
= 15.924
Therefore we can conclude that the difference between these two integers is 15.924.

If m∠ABC = 53° and m∠ECD = 40°, which statement explains whether the AA similarity postulate can be used to determine whether ΔBAC ~ ΔEDC?
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ≅ .
No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.
No, the AA similarity postulate cannot be used because a reflection over line f will establish that and are not congruent.
Similar triangles may or may not be congruent.
The true statement is (c) No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.
The given parameters are:
[tex]\mathbf{\angle ABC = 53}[/tex]
[tex]\mathbf{\angle ECD = 40}[/tex]
From the image of the triangles (see attachment);
The triangles are similar if:
[tex]\mathbf{\angle ABC + \angle ECD = 90}[/tex]
Substitute the given values
[tex]\mathbf{53 + 40 = 90}[/tex]
[tex]\mathbf{93 = 90}[/tex]
The above equation is not true, because:
[tex]\mathbf{93 \ne 90}[/tex]
Hence, the triangles are not similar by AA

If h(x) = 2x + 1, find h(x+2).
Answer:
h(x + 2) = 2x + 5
Step-by-step explanation:
So if you add 2 to x, you have to change the x value.
Since h(x) = 2x + 1, h(x + 2) = 2(x + 2) + 1
h(x + 2) = 2x + 5

The acceleration due to gravity is g= 9.8 m/s. One student argues that acceleration is a variable, since it is represented by a letter. Another student claims it’s a constant, since it doesn’t change. Who is right?
Answer:
Acceleration due to gravity is a constant
Step-by-step explanation:
gravity is a force pulling an object to the center of the earth this force also never changes
Acceleration due to gravity is a constant for the earth at every place.
What is acceleration?Acceleration of any object is defined as the variation in the speed of the object with the variation of time. Acceleration is a vector term and to define it we require both the magnitude and the direction. The unit of acceleration can be m / sec², miles / sec², etc.
Gravity is a force that pulls an object toward the center of the earth, and this force never changes, hence acceleration due to gravity is a constant for the earth in all places.
Therefore, acceleration due to gravity is a constant for the earth at every place.

Each letter in the expression shown to the right represents a digit other than zero. Different letters represent different digits and the same letter always represents the same digit. What is the smallest whole number that can be the value of this expression?
Answer:
The smallest whole number that can be the value of the expression is 2
Step-by-step explanation:
Given that the letters represent different digits, to get the smallest whole number value for the expression we have;
[tex]\dfrac{K \times A \times N \times G \times A \times R \times O \times O}{G \times A \times M \times E}[/tex]
The letters G and A cancel out from the numerator and the denominator to give;
[tex]\dfrac{K \times A \times N \times R \times O \times O}{M \times E}[/tex]
Therefore, the smallest whole number can be from 2 and above as the product of six digits is more than one times the product of two digits
If we put
K = 2, A = 3, N = 4, R = 6, O = 1, M = 9, and E = 8, we have;
[tex]\dfrac{2 \times 3 \times 4 \times 6 \times 1 \times 1}{9 \times 8} = \dfrac{144}{72} =2[/tex]
Therefore, the smallest whole number that can be the value of the expression = 2.

which number, when substituted for x, make the equation 4x+ 8= 16 true
Answer:
x=2
Step-by-step explanation:
ok so this is just a substitution problem.
we need to get the variable (x) by itself on one side.
4x+8=16. so, lets remove 8 from the left side, and whatever we do to one side also has to happen to the other.
4x+8=16
-8 -8
4x=8. So now, we want to get 4 separate from x, and the only thing we can do is divide.
4x=8
/4 /4
x=2. there you have it, x is 2.
Answer:
X=2

Which is correct:
A. f(n) = 3(2)n; 59 strands of bacteria
B. f(n) = 2(3)n; 82 strands of bacteria
C. f(n) = 3(2)n; 48 strands of bacteria
D. f(n) = 2(3)n; 162 strands of bacteria
Answer:
C.[tex]f(n) = 3(2)^n[/tex] ; 48 strands of bacteria
Step-by-step explanation:
Fred placed 3 strands of bacteria in a petri dish.
The bacteria strands double every hour.
Formula : y = ab^x
Where a is the initial value
b = growth rate
x = hours
So, A formula to represent how many bacteria strands are present at the nth hour : [tex]f(n)=3(2)^n[/tex]
Now we are supposed to find how many strands of bacteria are present at 4 hours.
Substitute the value in the formula :
[tex]f(4)=3(2)^{4}[/tex]
f(4)=48
Hence 48 strands of bacteria are present at 4 hours.
Answer:
f(n) = 3(2)n; 48 strands of bacteria

A building block is made by taking a 6 cm by 4 cm by 2 cm block and removing four cubes from the center of the block. The volume of the final block is 44 cm3.
A rectangular prism with a length of 6 centimeters, width of 4 centimeters, and height of 2 centimeters. 4 blocks are removed from the block with dimensions 6 by 4 by 2 centimeters.
What is the length of one side of one cube that was removed?
1 cm
1.5 cm
2 cm
2.5 cm
Answer:
(A)1 cm
Step-by-step explanation:
Volume of the Prism before the cubes were removed[tex]=6 X 4 X 2 = 48$ cm^3[/tex]
Volume of the Prism after the 4 cubes were removed[tex]=44$ cm^3[/tex]
Therefore, Volume of the 4 cubes

If Volume of the 4 cubes = 4 cubic centimeter
Volume of 1 cube =4/4 =1 cubic centimeterVolume of a cube of side length s[tex]=s^3[/tex]
Therefore:
[tex]s^3=1 cm^3\\$Side Length, s=1 cm[/tex]
The side length of 1 cube that was removed is 1 cm.

Parallelogram L M N O is shown. Angle M is (3 x minus 55) degrees, angle N is (5 y) degrees, and angle O is (2 x) degrees. In parallelogram LMNO, what are the values of x and y? x = 11, y = 14 x = 11, y = 25 x = 55, y = 14 x = 55, y = 25
Answer:
The correct option is:
x=55 , y = 14
Step-by-step explanation:
We know about the following features of a parallelogram:
Opposite sides are parallelOpposite side have equal lengthOpposite angles are equalSum of all angles is 360°For the parallelogram LMNO, <L and <N are opposite angles, <M and <O are opposite angles.
Are opposite angles are equal.
<M = <O
3x - 55 = 2x
3x - 2x = 55
x = 55
So
<M = 3x - 55 = 110°
<O = 2x = 110°
We know that the sum of angles is 360°
<L + <M + <N + <O = 360°
<L + <N + 110° + 110° = 360°
As <L and <N are opposite, both are equal. hence <L = <M = 5y
5y + 5y + 220° = 360°
10y + 220° = 360°
y = 14
Answer:
x = 55, y = 14
Step-by-step explain
it is X = 55, y = 14

6. He had Rs728.
7. There are 1875 pupils in the school.
Step-by-step explanation:
6.
He started with x amount of money.
He spent 1/4 of x. x - (1/4)x = (4/4)x - (1/4)x = (3/4)x
After buying the lottery tickets, he had (3/4)x left.
Then he spent 2/7 of the remainder on scratch cards.
He spent 2/7 of (3/4)x on scratch cards. Since he spent
2/7 of the reminder on scratch cards, he has 5/7 of the reminder left.
5/7 * (3/4)x = (15/28)x
He has (15/28)x left. He has Rs390 left.
(15/28)x = 390
15x = 390 * 28
15x = 10920
x = 728
Answer: He had Rs728.

8/15 of the pupils are girls.
1 - 8/15 = 15/15 - 8/15 = 7/15
7/15 of the pupils are boys.
Let x = total number of pupils in the school
(8/15)x = (7/15)x + 125
Multiply both sides by 15.
8x = 7x + 1875
x = 1875
Answer: There are 1875 pupils in the school.
