Dan’s new appliance arrived in a cardboard box in the shape of cube. What is the surface area of the cardboard box?
A cube has side lengths of 3 feet.
Use the formula S A = 6 s squared, where SA is the surface area of the cube and s is the length of each side.
18 Feet squared
36 Feet squared
54 Feet squared
324 Feet squared
15 points please help
Answer:
36
Step-by-step explanation:
it says 6 with a 2 so u multiply 6 by 2 and get 12 then u multiply the 12 by the 3 and get 36 SO SRY IF IM WRONG !!
Answer:
Option (3)
Step-by-step explanation:
Formula to calculate the surface area of a cardboard box in the shape of a cube is,
Surface area = 6(Side)²
If the length of the each side of the box is = 3 feet
Surface area of the cube = 6(3)²
= 6 × 9
= 54 square feet
Therefore, Surface area of the box in the shape of a cube is 54 square feet.
Option (3) is the correct option.

Solve each equation or formula for the specified variable.
y= 1/4x -12,for x
Answer:
Step-by-step explanation:
Y = 1/4x - 12
Adding 12 on both sides
12y = 1/4x
12y/ 1/4 = x
3y = x

Find an equation of the line that contains the point (-1,3) and is parallel to the line x+3y=6.
HELLPPPPPPPPPPPPPP PLEASE
Answer:
Step-by-step explanation:
3y = -x + 6
y = -1/3x + 2
y - 3 = -1/3(x + 1)
y - 3 = -1/3x - 1/3
y - 9/3 = -1/3x - 1/3
y = -1/3x + 8/3
How many multiples of 5 are there in between 100 and 300?
Answer:
39 multiplesStep-by-step explanation:
Consider AP:
105, 110, ..., 295As multiples of 5 between 100 and 300
The first term is 105, the common difference is 5, the last term is 295.
Use the nth term formula:
105 + 5(n - 1) = 2955(n - 1) = 190n - 1 = 190/5n - 1 = 38n = 39Answer:
Solution given:
first term [a]=100
last term[l]=300
common difference [d]=5
second term[b]=100+5=105
now
we have
l=a+(n-1)d
substituting value
300=100+(n-1)5
300-100=(n-1)5
200/5=n-1
40=n-1
n=40+1
there are 41 multiple in between 100 and 300/including it but no including its 41-2=39 multiple
Lainey bought a set of 20 markers for $6
What is the cost of 111 marker?
Answer:
370
Step-by-step explanation:
First find the unit rate aka price per pencil: 20 divided by 6 equals 3.333
Then find amount for all pencils
3.333 by 111 is 369.963
Then we round up to have a realistic amount of pencils to 370

What is 5% lower than 40?
Answer: 38
Step-by-step explanation:
Answer:
38
Step-by-step explanation:
Let's use benchmark fractions
What is 10% of 40?
that's 40/10 which is 4
What is half of 4?
4/2 = 2
That means 5% of 40 is 2
So then we do 40 - 2 = 38
The other way we can do it is by using percent proportions:
[tex]\frac{x}{95} \frac{40}{100} \\do:\\x=\frac{95 * 40}{100}[/tex]
[tex]x=\frac{3800}{100}[/tex]
[tex]x=38[/tex]

∆ ABC is isosceles with AB= AC= 7.5cm and BC= 0 cm .the height AD from A to BC, is 6cm . find the area of ∆ ABC what will be the height from C to AB i.e., CE
I have attached an image of the triangle.
BC = 9 cm
Answer:
CE = 7.2 cm
Step-by-step explanation:
In the attached triangle, we see that;
AB = AC = 7.5cm
BC = 9 cm
AD = 6cm
BC = 9cm
Formula for area of triangle is given as;
A = ½bh
Where b is base and h is height.
For the ∆ ABC with BC as base,
Area = ½ × 9 × 6 = 27 m²
Similarly, For ∆ ABC with AB as base,
Area = ½ × 7.5 × CE
Now, area from earlier is 27 cm²
Thus;
½ × 7.5 × CE = 27
Multiply both sides by 2 to get;
7.5CE = 54
CE = 54/7.5
CE = 7.2 cm

ABCD TSVU find the value of Y
Answer:
The value of y = 7.5 and the scale factor is 2/3.
Step-by-step explanation:
To get the scale factor, let's get the ratio of 17 to 25
[tex] \frac{17}{25.5} = \frac{2}{3} [/tex]
To check if 17 really is the 2/3 of 25.5
[tex]17 = \frac{2}{3} \times 25.5 \\ 17 = \frac{51}{3} \\ 17 = 17[/tex]
Therefore, if 17 is the 2/3 of 25.5, then the line (3y-3.5) is also the 2/3 of (3y+6).
[tex]3y - 3.5 = \frac{2}{3} (3y + 6) \\ 3(3y - 3.5) = 2(3y + 6) \\ 9y - 10.5 = 6y + 12 \\ 9y - 6y = 12 + 10.5 \\ 3y = 22.5 \\ y = 7.5[/tex]
Coordinates (2,5) (6,11) what's the equation of the line?
Answer:
y= 2x+1
Step-by-step explanation:
Using the general linear form y=mx+c
First find the gradient: change in y/change in x
11-5/6-2 = 6/3= 2
y=2x+c
Secondly find out c:
Use one of the coordinats
5= 2(2)+c
5=4+c
-4
1=c
y= 2x+1

A cylinder has a base diameter of 20ft and a height of 5ft what is its volume in cubic ft round to the nearest tenths place
Answer:
1571 ft^3
Step-by-step explanation:
Given data
diameter= 20ft
radius= 20/2= 10 ft
Height= 5ft
Volume of cylinder = πr^2h
Substitute
V= 3.142*10^2*5
V= 3.142*100*5
V= 1571 ft^3
Hence the volume is 1571 ft^3
Answer:
1580.8 ft^3

Rearrange t= 5s + 4 to make s the subject
Answer:
Subject 's' in terms of 't'
[tex]s = \frac{t-4}{5}[/tex]
Step-by-step explanation:
Explanation:-
Given that the subject 't in terms are 's'
Given that t = 5 s +4
subtracting '4' on both sides, we get
t - 4 = 5s +4-4
t - 4 = 5 s
Dividing '5' on both sides ,we get
[tex]\frac{t-4}{5} = \frac{5s}{5}[/tex]
[tex]\frac{5s}{5 } = \frac{t-4}{5}[/tex]
[tex]s = \frac{t-4}{5}[/tex]

1) (-5) - 5
2) (-10) + 11
Answer:
1) -10
2) 1
Step-by-step explanation:
1) (-5) - 5
- Removing the brackets won't change anything since it is subtraction, so now it will be - 5-5 which is equal to -10.
-5 -5 = -10
2) (-10) + 11
- The same case applies here since it is addition.
-10 + 11 = 1
Answer:
1) -10
2) -1
Step-by-step explanation:
[tex]( - 5) - 5 = - 10 \\ \\ ( - 10) + 11 = - 1 \: [/tex]
5x + 1 = 56
Solving 2 step equations?
Answer:
the x would equal to 11 ,so x=11
