Which inequality represents x is at least - 4?
Answer:
x is greater or equal to -4
[tex]x \geqslant - 4[/tex]
Solve
x + y = 100 x -y = 10
Pair of Equation
x + y = 100
x - y = 10
_____________ +
( x + y ) + ( x - y ) = 100 + 10
2x + y - y = 110
2x = 110
x = 110/2
x = 55
_________________________________
x - y = 10
55 - y = 10
- y = 10 - 55
- y = - 45
y = 45

What value of x would prove a || b (a parallel to b)? (Hint: Add consecutive interior angles to solve for x).
Answer:
x=8
Step-by-step explanation:
19x-13+6x-7=180
x=8
We have a || b (a parallel to b), the interior angle property. Therefore, the value of x would be 8.
What is the sum of interior angles of parallel lines?The sum of all the interior angles of parallel lines is equal to 180 degrees.
We have a || b (a parallel to b), the interior angle property
19x - 13 + 6x - 7 = 180
25x - 20 = 180
25x= 200
x = 8
Therefore, the value of x would be 8.

A farmer sells 7.5 kilograms of apples and pears at the farmer's market. 3/4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?
Answer: 1.87 kg of pears
Step-by-step explanation:
7.5 kg of both apples and pears were sold. 3/4 of this 7.5 kg is apples which means the amount of apples sold is:
= 7.5 * 3/4
= 5.63 kg of apples
The amount of pears sold would therefore be:
= Total amount sold - Amount of apples
= 7.5 - 5.63
= 1.87 kg of pears

Hi there!
»»————- ★ ————-««
I believe your answer is:
D) {(1, 2), (2,4), (−1, 2), (0,3)}
»»————- ★ ————-««
Here’s why:
A function is a relation in which one element of the domain is assigned to exactly one element of the range. This means that the domain (x) values must not repeat.⸻⸻⸻⸻
Option A's answer is incorrect, as the domain value of '5' repeats.
{(5, 0), (0, 1), (5, 2), (4,4)}
⸻⸻⸻⸻
Option B is not a function due to the repeating '-4' value.
{(0, 1), (−4, 1), (4, 2), (−4,−1)}
⸻⸻⸻⸻
The '3' in option C's given relation repeats.
{(3, 2), (2,1), (−1, 2), (3,3)}
⸻⸻⸻⸻
Option D is the correct answer, as there are no domain values that repeat.
{(1, 2), (2,4), (−1, 2), (0,3)}
Therefore, option D is a function.

Suppose that another outbreak has been detected. On Sept 1, there were 60 reported cases. A week later, there were 75 reported cases.
If the disease continues spreading exponentially, how many weeks after Sept 1 will 850 cases be expected? Round to the nearest weeks
Answer:
Cases will increase to 850 in half day
Step-by-step explanation:
Given
The number of reported cases increase from 60 to 75 in seven days (week)
rate of increase of cases = 75-60/7 = 15/7
Now, as per the exponential growth equation
[tex]P = P_0 * e^{r*t}[/tex]
Substituting the given values we get
[tex]850 = 60 * e^{\frac{15}{7} * t}\\e^{\frac{15}{7} * t} = 14.167[/tex]
Taking log on both sides we get
15/7 * t = 1.15
t = 1.15 *7/15
t = 0.537 days = half day

An inground pool is 34 feet long and x inches wide. Its brick walkway is 4 feet wide around the pool. What expression represents the area of the brick walkway?
Answer:
[tex]A_w=238x-2176[/tex]
Step-by-step explanation:
From the question we are told that:
Length of pool [tex]L=34ft[/tex]
Width of Pool [tex]W=x[/tex].
Brick walkway Width [tex]W_b=4[/tex]
Generally the expression for a Area of pool is mathematically given by
[tex]A=L*W[/tex]
[tex]A=34*x[/tex]
[tex]A=34x[/tex]
Generally the expression for a Area of pool + Walkway is mathematically given by
[tex]A'=L'*B'[/tex]
where
[tex]L' =L+2(W_b)[/tex]
[tex]L' =34+2(4)[/tex]
[tex]L'=34+8[/tex]
[tex]L'=272[/tex]
And
[tex]W'=W+2(W_b)[/tex]
[tex]W' =x+2(4)[/tex]
[tex]W' =x+8[/tex]
Therefore
[tex]A'=L'*B'[/tex]
[tex]A'=(272)*(x+8)[/tex]
[tex]A'=272x+2176[/tex]
Generally the expression for a Area of Walkway is mathematically given by
[tex]A_w=Area\ of\ Pool+Walkway-Area\ of\ Pool[/tex]
[tex]A_w=A'-A[/tex]
[tex]A_w=272x+2176-34x[/tex]
[tex]A_w=238x-2176[/tex]

3.8, , Three and StartFraction 6 over 25 EndFraction
3.8, Three and StartFraction 6 over 25 EndFraction,
Answer:
From greatest to least, the order is:
[tex]3.8,\ 3\frac{4}{9},\ 3\frac{6}{25}[/tex]
Step-by-step explanation:
Given
[tex]Closest\ Benchmark \to Number[/tex]
[tex]3\frac{6}{25} \to 3[/tex]
[tex]3\frac{4}{9} \to 4[/tex]
Required
Order [tex]3\frac{6}{25}, 3.8, 3\frac{4}{9}[/tex] from greatest to least
From the given parameters, we have:
[tex]3\frac{6}{25} \to 3[/tex]
[tex]3\frac{4}{9} \to 4[/tex]
This implies that:
[tex]3\frac{4}{9}\ >\ 3\frac{6}{25}[/tex] --- we know this from the nearest benchmark
Convert [tex]3\frac{4}{9}[/tex] to decimal
[tex]3\frac{4}{9} = 3.44[/tex]
By comparison;
[tex]3.8 >\ 3\frac{4}{9}[/tex]
Hence, the list is:
[tex]3.8,\ 3\frac{4}{9},\ 3\frac{6}{25}[/tex]
Jess is building a skateboarding ramp in the shape of a triangular prism with the dimensions shown. If Jess wants to cover all faces of the ramp with plywood, how much plywood will he need? A triangular prism. The rectangular sides are 12 feet by 3 feet, 12 feet by 5 feet, and 12 feet by 4 feet. The 2 triangular sides have a base of 3 feet and height of 4 feet.
Answer:
156 ft²
Step-by-step explanation:
Given :
The rectangular sides are 12 feet by 3 feet, 12 feet by 5 feet, and 12 feet by 4 feet.
The 2 triangular sides have a base of 3 feet and height of 4 feet
We sum the area of each side:
Area of triangular side = 1/2 * base * height
Since there are 2 triangular sides :
Total area of triangular side = 2(1/2 * base * height)
Triangular side = 2 * 1/2 * 3 * 4 = 12 feet²
Area of rectangle sides = lengtb * width
Area 1 = 12 * 3 = 36 ft²
Area 2 = 12 * 5 = 60 ft²
Area 3 = 12 * 4 = 48 ft²
Total = 12 + 36 + 60 + 48 = 156 ft²
Find the area of the shaded region.
