Could 10.7 cm,3.2 cm,and 5.5 cm be the side lenghts of a triangle
if pictures width 4+w and the length measures 8w+2, how much longer is the picture than it is wide?
The picture is 7w - 2 units longer than it is wide, this is found by subtracting the width (4+w) from the length (8w+2).
To find out how much longer the picture is than it is wide, we must compare the picture's length and width. Given the picture's width is 4+w and the length is 8w+2, we subtract the width from the length to find the difference:
Length - Width = (8w+2) - (4+w) = 8w + 2 - 4 - w = 7w - 2.
Therefore, the picture is 7w - 2 units longer than it is wide.

Which of the following statements are equivalent to the statement "price increased by 100%"?
Choose all correct answers.
(A) The price doubled
(B) The price is 150% of the price before
(C) The price was reduced by a quarter
(D) The price became a half of what it was before
(E) The price is now 1.5 of what it was before
(F) The price now is 66 2/3 % of what it was before
(G) The price now is 200% of what it was before
(H) The price is 75% of what it was before
The statements equivalent to a price increase of 100% are that the price doubled and the price is now 200% of the original. These statements mean the new price is twice the original amount.
When analyzing statements that describe a price increase of 100%, it is important to understand that this means the new price is twice the original price. Among the listed statements, the correct ones that are equivalent to a 100% increase in price are:
(A) The price doubled
(G) The price now is 200% of what it was before
These are equivalent because if a price doubles, it is 100% more, making the new price 200% of the original. This can be seen in practical examples, such as if a gumball costs 25 cents and the price doubles, it becomes 50 cents, or 200% of its original cost.

Final answer:
The actual product is less than the estimate. The numbers differ by less than one.
Explanation:
Javier rounded to the nearest half to estimate the product of 3 2/5 and -3 7/8.
To estimate the product, we can round both numbers to the nearest half, which gives us 3.5 and -3.5. Multiplying these rounded numbers gives an estimate of -12.25.
The actual product of 3 2/5 and -3 7/8 is -3.4. Therefore, the actual product is less than the estimate. The numbers differ by less than one.

How much work is needed to stretch this spring from x = 3.0 cm to x = 7.0 cm ?
The work done to stretch a spring is calculated using Hooke's Law, denoted by the formula W = 1/2kx², where 'k' is the spring constant and 'x' the displacement. The displacement is the difference between the final and initial lengths of the spring (7.0 cm - 3.0 cm). However, without the spring constant, a specific numerical answer cannot be provided.
Explanation:The problem requires calculating the work done to stretch a spring. This can be done using Hooke's Law in Physics, which states that the force necessary to extend or compress a spring by a distance 'x' from its equilibrium position is proportional to 'x'. The magnitude of the force applied is represented as F = kx, where 'k' is the spring constant. However, the work done, W, against this force is given by 1/2kx².
To calculate, we need to know the value of the spring constant 'k', and the displacement 'x', which is the difference between the final length (7.0 cm) and the initial length (3.0 cm) of the spring. Without the spring constant, we, unfortunately, cannot provide a numerical answer.

Janelle has 4 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 7mph and walks back at a speed of 3mph how long should she plan to spend walking back?
Final answer:
Janelle should plan to spend 3 hours walking back.
Explanation:
To find out how long Janelle should plan to spend walking back, we need to calculate the total time it takes her to run and walk. Since she runs at a speed of 7mph, she completes the distance of the race in 1 hour (4 miles / 7mph = 0.57 hours = 1 hour). Therefore, she spends 1 hour running and 3 hours left for walking. To find out the distance she walks back, we use the formula distance = speed x time. Since she walks at a speed of 3mph, the distance she walks back is 3mph x 3 hours = 9 miles.

Solve for x.
Fx-gx=h
If we solve the equation which is (F × x ) - (g × x ) = h , we will get the value of x as x = h / ( F - g ).
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
An equation is given which is :
(F × x ) - (g × x ) = h
We have to solve this equation to get the value of the variable x.
So, the value of x can be calculated as :
(F × x ) - (g × x ) = h
Taking common x from LHS :
x ( F - g ) = h
Dividing by ( F - g ) on both sides we get :
[ x ( F - g ) / ( F - g )] = h / ( F - g )
or
x = h / ( F - g )
Therefore , if we solve the equation which is (F × x ) - (g × x ) = h , we will get the value of x as x = h / ( F - g ).

The price of a pair of shoes is $45.90. The sales tax rate is 5%. How much sales tax do you need to pay?
Answer:
The sales tax to be paid for the pair of shoes is $2.29.
Step-by-step explanation:
If the price of a pair of shoes is $45.90, and the sales tax rate for it is of 5%, in order to know the sales tax to be paid we have to do the following calculation:
(45.90 x 5) / 100 = X
229.5 / 100 = X
2.295 = X
So, as we can see, the sales tax to be paid is $2.29

Felicity is placing a rectangle in the coordinate plane. She knows that the longer side of the rectangle is 3 times its shorter side. She places the longer side on the x-axis.
What coordinates should she assign to the top-right vertex of the rectangle?
Answer:
(3a,a)
Step-by-step explanation:
As you know the component on the X vertex is the first that is represented when setting point coordenates, and the second value is in the Y vertex, as you can see the value for Y is a, and in the problem says that the longer side is three times the short side, since the Y vertex is the short side, that means the X vertex will have the longer side, making it 3a. So the coordenates will be (3a,a).

which would not be a step in solving 3x + 1 + 2x = 2+ 4x?
To solve the equation 3x + 1 + 2x = 2 + 4x, you would first combine like terms, then eliminate variable terms on one side of the equation, and finally solve for x.
Explanation:In solving the equation 3x + 1 + 2x = 2 + 4x, the first step would be to combine like terms on both sides of the equation. This means adding or subtracting the same type of terms together. In this case, you would combine the x terms on the left side and the constant terms on the right side. The equation will then be simplified to 5x + 1 = 2 + 4x.
The next step would be to get rid of the variable terms on one side of the equation. To do this, you can subtract 4x from both sides of the equation. This will result in x + 1 = 2.
Finally, you can solve for x by subtracting 1 from both sides of the equation. This gives us the solution x = 1.

A trapezoid is made of a square with side lengths of 7 feet and an isosceles right triangle whose base and height are both 7 feet.What is the area?
The total area of the trapezoid is 73.5 square feet, calculated by adding the area of the square (49 square feet) to the area of the isosceles right triangle (24.5 square feet).
The area of a trapezoid consists of the area of a square and the area of an isosceles right triangle. Since the square has side lengths of 7 feet, its area is 49 square feet (7 feet x 7 feet). The isosceles right triangle, with both the base and the height being 7 feet, has an area of 24.5 square feet (1/2 x 7 feet x 7 feet). Therefore, the total area of the trapezoid is the sum of the areas of the square and the triangle.
Total area = Area of square + Area of triangle
Total area = 49 square feet + 24.5 square feet = 73.5 square feet.

Answer:
Option C. is the correct option.
Step-by-step explanation:
The given line in the graph passes through two points (0, 3) and (3, 7).
We have to find the equation of the line.
Since y = mx + c is the standard equation of a line
where m = slope of the line
c = y - intercept
Slope of a line m = [tex]\frac{(y-y')}{(x-x')}[/tex]
Now we put the values of x and y to find the slope of this line.
m = [tex]\frac{7-3}{3-0}=\frac{4}{3}[/tex]
Since (0, 3) passes through the line
3 = 0 + c
c = 3
Equation of the line will be
[tex]y=\frac{4}{3}x+3[/tex]
Option C. is the answer.
