Answers
Answer:
5 + -4
Step-by-step explanation:
5 - 4 = 1
5 + -4 = 1
Answer:
I think the answer is 5 + -4.
Step-by-step explanation:
That's because 5-4 is 1. And 5 + -4 is also 1. 5 + -4 reversed is 5 - 4 (you change the symbol and channge the last number from negative to positive or positive to negative). Sorry if this doesn't make sense or is wrong :3

Answer:Triangle DEF is congruent to triangle GHI.
I know it's already answered but I need points.
Only statement [2], triangle DEF is congruent to triangle GHI is correct.
What is triangle?A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given are three triangles ΔABC, ΔDEF, ΔIHG.
ΔDEF is congruent to ΔGHI as -
EF = IH (given)
∠E = ∠H (right angle)
FD = IG (given)
Using SAS congruent rule, ΔDEF ≅ ΔGHI
Therefore, only statement [2], triangle DEF is congruent to triangle GHI is correct.

What is its surface area in square units? Show your reasoning.
Answers
Answer:Two quadrilateral rectangles:
1. 6x5= 30
2. 5x10= 50
Two right triangles:
1. 10x6/2= 30
2. 10x6/2= 30
Then you add them all up:
30+50+30+30= 140 sq. units
The total surface area of the given figure is 168 square units.
Given that, the net has the two triangles are right triangles. All quadrilaterals are rectangles.
We need to find the surface area in square units for the given figure.
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
There is a different surface area formula for every geometrical shape, but the idea behind all is to get the total area occupied by all the faces of the objects.
Now, the area of the triangle=1/2 × Base × Height
=1/2 × 8 × 6=24 square units
Area of 2 triangles=2 × 24=48 square units
Area of rectangle = Length × width
Now, the area of a rectangle with dimensions length=10 units and width=5 units.
Area=10 × 5=50 square units
The area of a rectangle with dimensions of length=8 units and width=5 units.
Area=8 × 5=40 square units
The area of a rectangle with dimensions of length=6 units and width=5 units.
Area=6 × 5=30 square units
Total surface area=48+50+40+30 square units
=168 square units
Therefore, the total surface area of the given figure is 168 square units.

A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

All you have to do is add all the numbers up then divide by how how ever many numbers you added in this case it was 6 numbers so I divided my sum by that number and got my answer
The mean of the given series is negative 2.
What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
It is given that the series;
9, 7, 1, 8, –1, –36
All we have to do is add all the numbers up then divide by how how ever many numbers you added.
In this case it was 6 numbers so I divided the sum by that number.
Mean = 9 + 7 +1 + 8 -1 + -36/ 6
Mean = -2
Therefore, the mean of the given series is negative 2.

A weather balloon has a volume of 90.0 L when it is released from sea level 101 kPa. What is the atmospheric pressure on the balloon when it has grown to a size of 175.0 L?
Answers
Answer:
The final atmospheric pressure is 5.19 · 10⁴ Pa
Step-by-step explanation:
Assuming that the temperature of the air does not change, we can use Boyle's law, which states that for a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume. In formula,
pV = const.
where p is the gas pressure and V is the volume
The equation can also be rewritten as
p₁ V₁ = p₂ V₂
where in our problem we have:
p₁ = 1.03 · 10₅ Pa is the initial pressure (the atmospheric pressure at sea level)
V₁ = 90.0L is the initial volume
p₂ is the final pressure
V₂ = 175.0L is the final volume
Solving the equation for p2, we find the final pressure:
p₂ = p₁ v₁ divided by V₂ = (1.01 · 10⁵)(90.0) divided by 175.0 = 5.19 · 10⁴ Pa

Red: 12.5 square feet for $1.79
Blue: 40 square feet for $5.29
Green: 50 square feet for $8.49
Orange: 60 square feet for $6.00
Answers
Answer:
8.49
6.00
5.29
1.79
Step-by-step explanation:
Answer:
Orange, Blue, Red, Green.
Orange would be the best deal.
Step-by-step explanation:
In order to put the unit costs per square foot from least to greatest, let's find the unit cost per square root of each wrapping paper.
To find the unit cost per square root, we simply have to divide the cost over the amount of square feet. So:
Red:
[tex]c=\frac{1.79}{12.5}=\$0.1432\text{ per square foot}[/tex]
Blue:
[tex]c=\frac{5.29}{40}=\$0.13225\text{ per square foot}[/tex]
Green:
[tex]c=\frac{8.49}{50}=\$0.1698\text{ per square foot}[/tex]
Orange:
[tex]c=\frac{6}{60}=\$0.10\text{ per square foot}[/tex]
So, to cost of wrapping paper per foot from least to greatest is:
Orange, Blue, Red, Green.
So, orange would be the best deal.
And we're done!

During a closeout sale, some television models are discounted 40%. What was the original price to the nearest dollar of a television that now costs $1,485?
Answers
Answer:
$2,475
Step-by-step explanation:
1485/6= 247.5 247.5 x 10 = 2,475
You take out the zero's so you get $1,485 = 60% of the original price, so 1485 divided by 6. Then you take the number you get and times it by 10 and then you get the answer.
Based on the current cost and the discount, the original price of the television was $2,475.
The cost of the television now is $1,485 which is a discounted price of 40%.
Assuming the original price was x, the equation is:
Present cost = Original price x (1 - discount)
Solving gives:
1,485 = x × (1 - 40%)
1,485 = 0.6x
x = 1,485 / 0.6
x = $2,475
The original price was therefore $2,475.
