Answer:
120cm2
Step-by-step explanation:
6 x 8 = 48cm2
8 x 9 = 72cm2
48 + 72 = 120cm2
Answer:
120 m^2
Step-by-step explanation:
The box on the left is 6m x 8m, thus the area would be 48 m^2.
The box on the right is 9m x 8m, thus the area would be 72 m^2.
Adding both areas would give you the total area of 120 m^2.

The two Integers are [tex]10,10.[/tex]
What is Integer ?An Integer number that can be written without a fractional component.
We have,
Sum of two Integers [tex]=20[/tex]
Product of two Integers [tex]=100[/tex]
Now,
Let,
One integer [tex]=x[/tex]
Another integer [tex]=y[/tex]
So,
According to the question,
[tex]x+y= 20[/tex] [tex].....(i)[/tex]
[tex]x*y=100[/tex]
⇒ [tex]x=\frac{100}{y}[/tex] [tex].....(ii)[/tex]
Now,
Putting value of x in equation (i),
We get,
[tex]\frac{100}{y}+y= 20[/tex]
[tex]100+y^2=20y[/tex]
[tex]y^2-20y+100=0[/tex]
Using middle term split method,
[tex]y^2-10y-10y+100=0[/tex]
[tex]y(y-10)-10(y-10)=0[/tex]
[tex](y-10) (y-10)=0[/tex]
We get,
[tex](y-10)=0[/tex] and [tex](y-10)=0[/tex]
So, [tex]y=10[/tex]
Now, putting value of y in in equation (i),
[tex]x+10=20[/tex]
[tex]x=10[/tex]
So, two integers are [tex]10,10.[/tex]
Hence, we can say that the two Integers are [tex]10,10.[/tex]

What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The longest straw that can fit inside a 5-inch cylindrical cup, if the straw is placed at an angle in the cup, is 6 inches.
Then the approximate length of the cylinder's radius will be given by the Pythagoras theorem.
Let x be the length of the radius. Then we have
x² = 6² - 5²
x² = 36 - 25
x² = 11
x = √11
x = 3.316
x ≅ 3.3

1. An account is opened with a balance of $2800
earning 4.25% simple interest. What will be the
balance in the account in 30 years?
Answer:
The simple interest in the account will be $3570 and the total amount including principle and simple Interest will be $6370Step-by-step explanation:
firstly ,
Given That
principal(p)=$2800
Rate(R)=4.25%
Time(T)=30 years
now , we have from formula
simple interest (S.I)= P × T ×R / 100
= (2800×30×4.25) / 100
= $3570
Therefore , Simple Interest in 30 years will be $3570
now , we know
Amount(A) = Principal (P) + Interest (I)
= $2800 + $3570
= $ 6370
Therefore the simple interest in 30 years will be $3570 and the total amount in the bank will be $6370 .

Answer:yˆ=−0.175x2−3.786x+121.119
look at picture
Step-by-step explanation:
The quadratic regression equation for the data set is:
y^ = -0.175x²-3.786x+121.119
What is Quadratic Regression Equation?Quadratic regression is the process of determining the equation of a parabola that best fits a set of data. This set of data is a given set of graph points that make up the shape of a parabola. The equation of the parabola is y = ax² + bx + c, where a can never equal zero.
According to the given problem,
Let us choose any value of x,
x = 10
For this value of x we can see that the respective value of y= 50
Substituting the value of x in the equations to see which equation satisfies the value of y as 50.
Substituting the value of x in the equation:
y^ = -0.175x²-3.786x+121.119
y^ = 50
Hence, we can conclude that y^ = 0.175x² - 3.786 + 121.119 is the quadratic regression equation for the given data set.

a 400 g of a liquid of density 1.6g/cm3 is made from mixing liquids of density 1.2g/cm3 and 1.8g/cm3 find the mass of the liquid of density 1.2g/cm3
Answer:
133.33g
Step-by-step explanation:
Let the:
Mass of 1.2g/cm³ of liquid = x
Mass of 1.8g/cm³ of liquid = y
From our Question above, our system of equations is given as:
x + y = 400........ Equation 1
x = 400 - y
1.2 × x + 1.8 × y = 1.6 × 400
1.2x + 1.8y = 640..... Equation 2
We substitute, 400 - y for x in Equation 2
1.2(400 - y) + 1.8y = 640
480 - 1.2y + 1.8y = 640
- 1.2y + 1.8y = 640 - 480
0.6y = 160
y = 160/0.6y
y = 266.67 g
Solving for x
x = 400 - y
x = 400 - 266.67g
x = 133.33g
Therefore, the mass of the liquid of density 1.2g/cm³ is 133.33g
A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 9cm, and the base has a radius of 4cm. How much water is needed to fill 150 cups? Use 3.14 for π, and do not round your answer.
Answer:
22608cm³
Step-by-step explanation:
Step 1
We find how many liters of water can be contained in 1 cup. We do this by finding the volume of the cup.
Cup is shaped as a cone
The volume of a cone = πr²h/3
Where
r = radius = 4cm
h = height = 9cm
π = 3.14
Hence,
Volume of the cone (cup) =
3.14 × 4² × 9/3
= 150.72 cm³
Step 1
How much water is needed to fill 150 cups?
1 cup = 150.72 cm³ of water
150 cups = x
Cross Multiply
x = 150 × 150.72 cm³
x = 22608 cm³ of water
Therefore, 22608cm³ of water is needed to fill 150 cups
Miss Clara, the teacher at the school, has one
large classroom with 25 students. The
dimensions of the classroom are 30 units by
30 units. Each desk is two units wide by
three units long. How much space will be
leftover after all the desks are in the room?
Answer:
750 units.
Step-by-step explanation:
30 x 30 = 900 units (total space in the classroom)
2 x 3 = 6 units (how much space each desk takes up)
25 x 6 = 150 units (number of desks for each student)
900 - 150 = 750 units
Hope this helped!
