Answer:
option D
Step-by-step explanation:
Sum of measure of any 2 sides of a triangle should be greater than the measure of third side.
The triangle will not have the sides 1 foot, 3 feet, and 7 feet, as these sides do not satisfy the triangle inequality theorem so, option D is correct.
What is inequality?An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.
Given:
The sides of the triangle are, 1 foot, 3 feet, and 7 feet,
We know that the sum of two sides of a triangle is always greater than the third side,
Calculate the sum of sides as shown below,
1 + 3 = 4
Thus, 1 + 3 < 7.
Therefore, these are not the sides of the triangle.

Answer:
3/8
Step-by-step explanation:
7/8 - 1/2 = ?
First, we find the Least Common Denominator and rewrite the fractions with the common denominator.
(7/8 × 1/1) - (1/2 × 4/4)
= 7/8 - 4/8 = ?
Now that the denominators are the same, we can subtract the numerators.
7-4/8 = 3/8
This fraction can't be reduced since it is already in its simplest form. Therefore, 7/8 - 1/2 = 3/8

You can look at the graph and see to get to from point (-3, -1) to point (2, 4) you rise up (change in y) 5 units and run (change in x) 5 units. This means the slope is 5 / 5 which is equal to 1.
sally has 2 cats and each cat eats 1/4 of a tin of cat food each day. sally buys 7 tins of cat food. for how many days will the cat food feed her two cats?
Division is one of the four fundamental arithmetic operations. The number of days this cat food will last is 14 days.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that each cat eats 1/4 of a tin of cat food each day. Therefore, the amount of food that two cats will eat in a day is,
= 2 × 1/4 of a tin of cat food each day
= 1/2 of a tin of cat food each day
Further, it is given that Sally buys 7 tins of cat food. Therefore, the number of days this cat food will last is,
= Total cat food / Cat food needed in a day
= 7tin of cat food / 1/2 of a tin of cat food each day
= 14 days
Hence, the number of days this cat food will last is 14 days.

Use the number line to add −3/5 and 1 1/4.
Answer:
13/20
Step-by-step explanation:
You can write 1 1/4 as 5/4. Any fraction that has the same number in the numerator and the denominator equals 1. For example 4/4 = 1, 20/20 =1, 5/5 = 1 and so on.
I can rewrite 1 1/4 as 4/4 + 1/4 = 5/4
Now we want to add -3/5 and 5/4. We need a common denominator because the pieces of the fractions are not equal. The smallest number that 5 and 4 will go into is 20. Si U an going to write the two fractions with 20 as the denominator.
-3/5 = -12/20 I multiplied the top and the bottom of -3/5 with 4.
5/4 = 25/20 I multiplied the top and the bottom of 5/4 by 5
-12/20 + 25/20 = 13/20

A rock is thrown from the top of a ladder. The function
h(t) = –16t2 + 120t + 10 gives the height of the rock t seconds after it is
thrown a certain number of feet.
What is the height of the rock at 5 seconds?
Answer:
h'(t)=88
Step-by-step explanation:
h'(t)=d/dt (-16t x 2 + 120t + 10
h'(t)=d/dt (-32t + 120t + 10)
h'(t)=d/dt (88t + 10)
h'(t)=d/dt (88t) + d/dt (10)
h'(t)=88 + 0

At Open Skate Night, admission is $3.75 with a membership card and $5.00 without a membership card. Skate rentals are $3.00. The Moores paid $6 more for skate rentals than the Cotters did. Together, the two families paid $42 for skate rentals. How many pairs of skates did the Moores rent? The Moores rented 9 pairs of skates.
Answer: 8 skates
Step-by-step explanation:
Given that:
Skate rental = $3
Let number of skates rented by cotters = x
Hence, amount paid by cotters = 3x
The Moores paid $6 more
Moores amount = 3x + 6
Combined amount paid = 42
3x + 3x + 6 = 42
6x + 6 = 42
6x = 42 - 6
6x = 36
x = 36 / 6
x = 6
Hence, amount spent by the Moore's:
3x + 6
3(6) + 6 = 18 + 6 = $24
Cost per skate rental = $3
Hence x number of skates rented by the Moore's = $24 / 3 = 8 skates
the square root of 4/49
Answer:
[tex]\frac{2}{7}[/tex]
Step-by-step explanation:
Simplify the numerator and the denominator.
The square root of 4/49 is 2/7.
Given that a fraction 4/49 we need to find the square root of this fraction,
To find the square root of a fraction, you need to find the square root of both the numerator and the denominator separately. Let's apply this to the fraction 4/49.
Step 1: Find the square root of the numerator:
The numerator is 4. Taking the square root of 4 gives us √4 = 2.
Step 2: Find the square root of the denominator:
The denominator is 49. Taking the square root of 49 gives us √49 = 7.
Step 3: Form the new fraction:
The square root of the fraction 4/49 is (√4)/(√49), which is 2/7.
Therefore, the square root of 4/49 is 2/7.

Given :
Duc and Hue baked cookies to help with their community's fundraiser. Duc baked 10 less than twice the number of cookies Hue baked. Together they baked 80 cookies.The following steps can be used in order to determine the system of equations models given situation:
Step 1 - Let the total number of cookies Duc baked be 'd' and the total number of cookies Hue baked be 'h'.
Step 2 - The linear equation that represents the total number of cookies Hue and Duc baked is:
d + h = 80
d = 80 - h --- (1)
Step 3 - The linear equation that represents that Duc baked 10 less than twice the number of cookies Hue baked is:
d = 2h - 10 --- (2)
Step 4 - Substitute the value of 'd' in equation (2).
2h - 10 = 80 - h

A microbiologist is growing bacteria cultures in the lab. After 5 minutes, a bacteria colony has 1.3 million organisms. After 12 minutes, the same colony has 41.5 million organisms. After 15 minutes, the colony has grown to 101.3 million organisms. Is this a proportional or non-proportional relationship?
Answer: Non proportional
Step-by-step explanation:
To know if the values given are proportional or not, we will use the formula:
y = kx
where
y = number of organisms
x = number of minutes
k = constant of proportionality
After 5 minutes, a bacteria colony has 1.3 million organisms. Using the formula, y = kx
1,300,000 = 5k
k = 1,300,000 / 5
k = 260,000
After 12 minutes, the same colony has 41.5 million organisms. Using y= kx
41,500,000 = 12x
x = 41500000 / 12
x = 3458333.8
After 15 minutes, the colony has grown to 101.3 million organisms.
y = kx
101,300,000 = 15k
k = 101,300,000 / 15
k = 6753333.8
It is a non-proportional relationship as the constant of proportionality is different for each.
Given f(x) = 3x + 2 andg(x) = -2x - 4, find h(x) = f(x) - g(x).
Answer:
h(x) = 5x+6
Step-by-step explanation:
h(x) = f(x) - g(x)
h(x) = 3x+2 - (-2x-4)
h(x) = 3x+2 + 2x+4
h(x) = 5x+6
All we need to do is plug in the equations for f(x) and g(x) into h(x)
Let's do it
f(x) = 3x + 2 and g(x) = -2x -4
h(x) = f(x) - g(x)
h(x) = (3x + 2) - (-2x - 4)
Combine like terms
(3x) - (-2x) → 3x + 2x → 5x
(+2) - (-4) → 2 + 4 → 6
Let's put them together
h(x) = 5x + 6
