Answer 2

Final answer:

Since the area of one side is 1.44 m², the total surface area is 8.64 m².

Explanation:

To find the total surface area that will be painted on a cube-shaped table with an edge length of 1.2 m, we use the formula for the surface area of a cube, which is 6 times the area of one side.

Calculating the area of one side (1.2 m × 1.2 m) gives us 1.44 m². Multiplying this by 6 (6 × 1.44 m²) gives the total surface area which is 8.64 m². Therefore, the correct answer to drag and drop into the box is 8.64 m².

Explanation:

Let
P = area of triangle ABC
Q = area of triangle ACD

The two areas mentioned above are in ratio 1.5:1 which basically means
P = 1.5*k
Q = 1*k
for some value k
Notice how P/Q = (1.5k)/(1k) = 1.5 which proves that P:Q = 1.5:1

We can find the value of k by determining the area of triangle ABC
P = area of triangle ABC
P = (base)*(height)/2
P = 36*10/2
P = 360/2
P = 180

If P = 180, then
P = 1.5*k
1.5*k = 180
k = 180/1.5
k = 120

Telling us that
Q = 1*k
Q = 1*120
Q = 120
Q = area of triangle ACD
area of triangle ACD = 120
note how P/Q = 180/120 = 1.5 so P:Q = 1.5:1

We'll use this area to find the base of triangle ACD which is AD

Area of Triangle ACD = (base)*(height)/2
120 = AD*10/2
120*2 = AD*10
240 = AD*10
240/10 = AD
24 = AD
AD = 24

Lucy is a dress maker. She sews 4/7 of a dress in 3/4 hour. Lucy sews at a constant rate. At this rate, how many dresses does Lucy sew in one?

Answers

To find out how many dresses she can sew in one hour, divide the fraction of the dress she makes by the number of hours it takes for her to make the dress.

[tex]\sf\dfrac{4}{7}\div\dfrac{3}{4}[/tex]

When dividing fractions we flip the one we're dividing by and multiply:

[tex]\sf\dfrac{4}{7}\times\dfrac{4}{3}[/tex]

Multiply the numerators and denominators together:

[tex]\boxed{\sf\dfrac{16}{21}}[/tex]

So she sews 16/21 of a dress in one hour.

a 20 foot ladder leans against a wall so that the base of the ladder is 8 feet from the base of the building. what angle does the ladder make with the ground?

Answers

66.42° you can just do 66.4°

use cos(x)8/20

The ladder makes an angle of 63.43 degrees with the ground.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that 20 foot ladder leans against a wall so that the base of the ladder is 8 feet from the base of the building

We need to find the angle which the ladder make with the ground.

tan(x) = opposite side / adjacent side

In this case, the opposite side is the height of the building, which is 20 feet.

The adjacent side is the distance from the wall to the base of the ladder, which is 8 feet.

Plugging in the values:

tan(x) = 20 / 8

x=tan⁻¹(20/8)

x=63.43 degrees

x is the angle

Hence, the ladder makes an angle of 63.43 degrees with the ground.

Gene has a gasoline budget of $275 per month. He uses an average of $7 of gasoline each day he drives. Which of the following equations represents how much money is left in his gasoline budget after x days of driving?

Answers

Final answer:

The equation to represent how much money is left in Gene's gasoline budget after driving for x days is y = 275 - 7x, where x is the number of days Gene drives and y is the money left in the budget.

Explanation:

The equation representing how much money is left in Gene's gasoline budget after driving for x days can be expressed as y = 275 - 7x. Here, 275 represents the monthly gasoline budget, 7 is the cost of gasoline each day, and x is the number of days. If we plot y against x, we can visualize how Gene's monthly gasoline budget decreases by $7 for each day he drives.

This equation is a simple example of a linear equation, which describes a straight line in a coordinate system. The variable x is the independent variable (number of days driven) and y is the dependent variable (money left in the budget). The slope of the line (-7) represents the rate at which the budget decreases each day.

what is yhe best approximation of the value of w?
A) 1.4 cm
B) 4.0 cm
C) 6.0 cm
D) 7.3 cm

Answers

b 4.0 cm because if you think about it the one that says 3.3 cm is actually just slightly shorter than w so it has to be 4.0cm

Answer

B) 4.0 cm

Explanation

First, we can adapt the law of sines to the notation of our triangle:

[tex]\frac{sin(W)}{w} =\frac{sin(U)}{u}[/tex]

Now, we can infer from our diagram that [tex]W=39[/tex], [tex]U=31[/tex], and [tex]u=3.3[/tex], so we can replace the values in our previous expression:

[tex]\frac{sin(W)}{w} =\frac{sin(U)}{u}[/tex]

[tex]\frac{sin(39)}{w} =\frac{sin(31)}{3.3}[/tex]

Finally, we can solve for [tex]w[/tex]:

[tex]\frac{3.3sin(39)}{w} =sin(31)[/tex]

[tex]3.3sin(39)=wsin(31)[/tex]

[tex]\frac{3.3sin(39)}{sin(31)} =w[/tex]

[tex]w=\frac{3.3sin(39)}{sin(31)}[/tex]

[tex]w=4.03224[/tex]

Which rounds to [tex]w=4.0[/tex]

We can conclude that the best approximation of w is 4.0 cm

"write an equation in slope-intercept form of the line satisfying the given conditions."

The line passes through (-3,2) and is parallel to the line whose equation is y = 4x + 1.

How do I do this problem? Show all work.

Answers

The given line has a slope of 4.
This is because y = 4x+1 is in the form y = mx+b (m = 4 is the slope)

Any line parallel to the given line is also going to have the same slope of m = 4

Plug in m = 4 and (x,y) = (-3,2) and then solve for b
y = mx+b
2 = 4(-3)+b
2 = -12+b
2+12 = -12+b+12
14 = b
b = 14

So m = 4 and b = 14 means that y = mx+b turns into y = 4x+14

----------------------------------------

Final Answer: y = 4x+14

If volume of a right rectangular shipping carton is 948.75 cubic meters and the height of the shipping carton is 11 meters, and the width is 7.5 meters then length is 11.5 meters.

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that volume of a right rectangular shipping carton is 948.75 cubic meters.

The height of the shipping carton is 11 meters, and the width is 7.5 meters.

We have to find the length of the shipping carton

V=Length × width × height

V= Length x 7.5 x 11

948.75 = 82.5 length

Divide both sides by 82.5

Length = 948.75/82.5

Length = 11.5 meters

Hence, if volume of a right rectangular shipping carton is 948.75 cubic meters and the height of the shipping carton is 11 meters, and the width is 7.5 meters then length is 11.5 meters.

Answers

No solution would be the answer.

ANSWER

The given system of equations has no solution.

EXPLANATION

We write the two equations in the slope-intercept form,

[tex]y = mx + c[/tex]

The first equation is
[tex]2x - y = 7[/tex]

We make y the subject to obtain,

[tex]y = 2x - 7 - - (1)[/tex]

The second equation is already in slope intercept form.

[tex]y = 2x + 3 - - (2)[/tex]

We can see that the two equations have the same slope but different y-intercept. This implies that, the two equations will never intersect. Therefore the system of equations has no solution.
