I just need it to be written in an expression and then simplified
The temperature increase can be represented by the expression 7°F + 7°F, which simplifies to 14°F.
Explanation:The expression to represent the temperature increase from -7 degrees Fahrenheit at 6:00 am to 7 degrees Fahrenheit at noon is as follows:
Temperature increase = Final temperature - Initial temperature
Substituting the values, we get:
Temperature increase = 7°F - (-7°F)

Deon plans to ride a 15-mi bicycle trail. If his average is 20mi/h, with equation can he use to find the time T, in hours, for the ride ?
Distance traveled by Deon to ride a bicycle trail = 15 mile
Average speed of Deon to ride a bicycle trail = 20 mi/hour
Let 'T' be the time taken to ride the bicycle trail.
We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.
Distance =[tex]\frac{Speed}{time}[/tex]
[tex]15 = \frac{20}{T}[/tex]
So, [tex]T = \frac{20}{15}[/tex]
This equation will be used to find the time 'T' in hours for the ride.
How long is the piece of string?
Answer:
C) 14 units
Step-by-step explanation:
The equation is in standard form, so the larger denominator is the square of the semi-major axis. That length is √49 = 7, so the major axis length is 2·7 = 14. This length is the length of the string.
Write the perimeter of the floor plan shown as an algebraic expression in x.
Answer:
Perimeter = 2x + 64
Step-by-step explanation:
Perimeter = Sum of the lengths of the borders
From the given figure, we need to find the missing length.
Missing length = 18 - 10 = 8
Another missing length = (x + 14) - (x + 8) = x + 14 - x - 8
= 14 -8
= 6
Now let's add all the sides.
Perimeter = x + 14 + 8 + 6 + 10 + x + 8 + 18
Now add all the x terms and constants
Perimeter = 2x + 64
Which statement is false?
A. The number zero is a rational number.
B. Some irrational numbers are also rational numbers.
C. Every irrational number is a real number.
D. Every integer is a rational number.
Need answers ASAP, Thanks!
The false statement is B: 'Some irrational numbers are also rational numbers.' This is incorrect because a number cannot be both rational and irrational by definition.
The false statement among the options provided is option B: Some irrational numbers are also rational numbers. This is false because by definition, irrational numbers and rational numbers are distinct sets of numbers with no overlap. A rational number can be written as a ratio of two integers, which means it can be expressed as a fraction. On the other hand, an irrational number cannot be written as a ratio of integers. Thus, a number cannot be both rational and irrational at the same time.
To clarify the other options, option A is true because zero can be represented as the ratio 0/1, making it a rational number. Option C is true because irrational numbers such as π (pi) and √2 (the square root of 2) are indeed part of the set of real numbers. Option D is true because all integers can be expressed as a ratio where the denominator is 1, making every integer a rational number.

Answer:
the answer is point N
Step-by-step explanation:
i dont have a graph to explain
The midpoint of a line segment is calculated using the formula Midpoint = ((x1 + x2)/2 , (y1 + y2)/2), which finds the average of the x-coordinates and y-coordinates of the two points. Unfortunately, without specific points, we can't provide a concrete midpoint.
Explanation:Unfortunately, your question is slightly unclear as we need more detail to accurately determine the midpoint of the segment. Generally, if you want to find the midpoint of a segment, you need two defined points. Knowing these two points, you can calculate the midpoint using the formula: Midpoint = ((x1 + x2)/2 , (y1 + y2)/2). This formula calculates the average of the x-coordinates and y-coordinates of the two points, which gives you the coordinates of the midpoint.

A and B are not independent events because P(A|B)=P(A) and P(B|A)=P(B) .
A and B are independent events because P(A|B)=P(B) and P(B|A)=P(A) .
A and B are not independent events because P(A|B)=P(B) and P(B|A)=P(A) .
Answer:
A and B are not independent events because P(A|B)≠P(A)
is the correct answer.
Step-by-step explanation:
If A and B are independent then we must have
P(AB) = P(A) P(B) and also
P(A/B) = P(A)
We are given that
A and B are two events.
Let P(A)=0.5 , P(B)=0.25 , and P(A and B)=0.15 .
P(A/B) = P(AB)/P(B) = 0.15/0.5 = 0.3
i.e. P(A/B) is not equal P(A)
Similarly P(B/A) = P(AB)/P(A) = 0.15/0.25 = 0.6 not equal to P(B)
Hence A and B are not independent.

A dilation is a function because every point on the pre-image corresponds to exactly one point on the image.
A dilation is a function because the scale factor is always greater than 1.
A dilation is not a function because a point on the pre-image could be mapped to more than one point on the image.
A dilation is not a function because the image is not congruent to the pre-image.
Answer:
Dilation : The meaning of Dilation is that by taking a fixed center and certain real number we can either enlarge an image or reduce it's size without actually changing it's shape. it totally depends on amount by which we are dilating if it is a real number greater than 1 the size of image increases otherwise shrinks means smaller in size.
The original image is called Pre-image and after dilation that changed image is called image.
So, we can say that Dilation is a function because for each different scale factor or different real number we get different images.
So, Out of all the four options given first looks completely true about Dilation.
i.e A dilation is a function because every point on the pre-image corresponds to exactly one point on the image.
A dilation is a function because every point on the pre-image corresponds to exactly one point on the image. This is the definition of a function in mathematics. The scale factor and the congruity of the image to the pre-image are irrelevant to the classification of dilation as a function.
Explanation:The correct statement is:
A dilation is a function because every point on the pre-image corresponds to exactly one point on the image
. In mathematics, dilation is a transformation that changes the size, but not the shape, of a figure. For a dilation to qualify as a function, each point in the pre-image must correspond to exactly one point in the image, without any point in the pre-image being mapped to more than one point in the image. This is the definition of a function: a relation from a set of inputs (the pre-image) to a set of possible outputs (the image) where each input is related to exactly one output. The scale factor and the congruity of the image to the pre-image have no bearing on whether a dilation is a function or not.

Solve for x.
2x^2-4x=0
Hey there!!
Equation given :
2x² - 4x = 0
Taking the common terms
2x ( x - 2 ) = 0
Divide by 2x on both sides
x - 2 = 0
Adding 2 on both sides ...
x = 2
And another answer would be zero as the whole equation is zero,
Hence the answer : ( 0 , 2 )
Hope it helps@+!!
The value x for equation 2x² - 4x = 0 is 2.
Given equation:
2x² - 4x = 0
Add 4x on both side,
2x² = 4x
Divide x on both side
2x = 4
Divide 2 on both side,
x = 2.
Therefore, the value x for equation 2x² - 4x = 0 is 2.

The ratio of cats to dogs seen by a veterinarian on one day is 2 to 5. If the vet saw 40 dogs in one day how many cats did he see
Answer:
He sees 16 cats that day
Step-by-step explanation:
If the veterinarian sees 5 dogs a day then he also sees 2 cats.
If he sees 40 dogs a day then,
⇒[tex]\frac{2}{5} *40[/tex]
=[tex]16[/tex] Cats
He sees 16 cats that day.
The correct option is C.
Approximately 29 dogs were seen by the vet in one day.
To solve this problem, we first need to find the fraction of dogs among the total animals seen by the vet.
Given that the ratio of cats to dogs is 2 to 5, the total parts in this ratio is 2 + 5 = 7.
Now, to find the fraction representing dogs, we divide the number of parts representing dogs (5) by the total parts (7). This gives us 5/7.
Next, to find out how many of the 40 animals were dogs, we multiply the total number of animals seen (40) by the fraction representing dogs:
40 animals × (5/7) = (40 × 5) / 7 = 200/7 ≈ 28.57
Since we're looking for an approximation, we round this to the nearest whole number, which is 29.
So, approximately 29 of the animals seen were dogs, which corresponds to option C.
The complete question is here:
The ratio of cats to dogs seen by a vet in a day is about 2 to 5. If a vet saw 40 animals in one day, about how many were dogs?
A. 5
B. 12
C. 29
D. 40
