Final answer:
The total distance from the beginning of the first house's lawn to the end of the third house's lawn is 1050 feet. This calculation is done by adding the length of the first house's lawn (300 feet), the second house's (250 feet), and double the second's lawn for the third house's (500 feet).
Explanation:
To calculate the total length of the lawns from the first to the third house, we first determine the length of each lawn individually and then add them together:
The first house has a lawn that is 300 feet long.
The second house has a lawn that is 50 feet shorter than the first lawn, so it is 300 - 50 = 250 feet long.
The third house has a lawn that is twice the length of the second house's lawn, so it is 2 × 250 = 500 feet long.
Add the lengths of the three lawns together to find the total distance from the beginning of the first house's lawn to the end of the third house's lawn:
300 feet + 250 feet + 500 feet = 1050 feet
Therefore, it is 1050 feet from the beginning of the first house's lawn to the end of the third house's lawn.
The length of a rectangle is 5 m less than twice the width, and the area of the rectangle is 52 m^2. Find the dimensions of the rectangle.
length is 8m
Width is 6.5m
Explanation:
Let, width = b
So, length = 2b-5
area = 52[tex]m^{2}[/tex]
We know,
area of rectangle = length X width
So, [tex]52m^{2}[/tex] = [tex](2b-5) X b[/tex]
On solving the above equation, we get
Width, b = 6.5m
length, l = 8m
What is the answer to -12=4+c
Answer:
c=-16
Step-by-step explanation:
We want to solve for c in the equation:
-12=4+c
We add the additive inverse of 4 to both sides of the equation to obtain:
[tex] - 12 + - 4 = 4 + - 4 + c[/tex]
We simplify to obtain:
[tex] - 12 - 4 = 4 - 4 + c[/tex]
We simplify further to get:
[tex] - 16= 0 + c[/tex]
Therefore
[tex] - 16 = c[/tex]
Or
[tex]c = - 16[/tex]
C = 5/9 x ( F - 32)
176*F = ?? *C
The original temperature conversion equation is Tc = 5/9 x (T-f - 32). When converting 176 degrees Fahrenheit, it is multiplied by 5/9 to get approximately 108.89 degrees Celsius.
The equation provided by the student, C = 5/9 x (F - 32), is used to convert a temperature from Fahrenheit (F) to Celsius (C). To find the factor to convert Fahrenheit to Celsius directly, we can manipulate the given formula. The request seems to be asking for the conversion factor that is applied to Fahrenheit to get Celsius. However, the original equation needs to be rewritten correctly as: TC = (5/9) × (T-F - 32). From this, we infer that each degree Fahrenheit is equivalent to 5/9 of a degree Celsius. Therefore, 176°F would convert to 176 × (5/9) = 980/9 or approximately 108.89°C.

predicts the height, in meters of an object t seconds after a person launches it into the air.
It will take _ seconds for the object to hit the ground.
Answer:
8 seconds
Step-by-step explanation:
Given
h = - 5t² + 40t
When the object hits the ground then h = 0
Substitute h = 0 into the function and solve for t
- 5t² + 40t = 0 ← factor out - 5t from each term
- 5t(t - 8) = 0
Equate each factor to zero and solve for t
- 5t = 0 ⇒ t = 0
t - 8 = 0 ⇒ t = 8
t= 0 denotes the time of launch
t = 8 denotes the time it hits the ground
0.63 ÷ 1.638 what is ir
Answer:
[tex]0.3846154[/tex]
Step-by-step explanation:
We want to perform the following division:
0.63 ÷ 1.638
Let us convert everything to fraction to get:
[tex]\frac{63}{100}\div \frac{1638}{1000}[/tex]
We multiply by the reciprocal of the second fraction to get:
[tex]\frac{63}{100}\times \frac{1000}{1638}[/tex]
[tex]=\frac{63}{1638}*10[/tex]
[tex]=0.03846154*10=0.3846154[/tex]
Final answer:
To find the result of 0.63 divided by 1.638, you multiply both numbers by 1000 to remove the decimals and then divide, resulting in approximately 0.384612.
Explanation:
The question asks for the result of dividing 0.63 by 1.638. To solve this problem, you perform division as you would with any two numbers. The steps are as follows:
Set up the division problem: 0.63 ÷ 1.638.
To make the division simpler, you can multiply both the divisor (1.638) and the dividend (0.63) by powers of 10 to remove the decimals. In this case, multiply both by 1000 to get 630 ÷ 1638.
Perform the division: 630 divided by 1638 equals approximately 0.384612.
Thus, 0.63 ÷ 1.638 is approximately 0.384612.

identify this coefficient 8x
Answer:
8
Step-by-step explanation:
The term 8x is a product (as is any term). It is the product of a constant coefficient (8) and a variable (x). The "coefficient" is the multiplier of the variable of interest, so is 8 in this term.
_____
The word "coefficient" is often used to refer to the constant multiplier in any term. For example, in the term 6xy, if we just ask for the coefficient, we are interested in the value 6.
On the other hand, if we ask for the coefficient of y in that term, we expect to be told it is 6x. That is, the "coefficient" is the multiplier of the specified variable or constellation of variables.
The coefficient in the expression 8x is the number 8, which is the numerical factor that multiplies the variable x.
Identifying the Coefficient in the Expression 8x
To identify the coefficient in the expression 8x, we need to recognize that a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. In the case of 8x, the coefficient is 8. This means that 8 is the number by which the variable x is being multiplied. Coefficients play a crucial role in equations and functions, as they determine the proportionality and scale of the variable's effect within the expression.
For example, if x represents the number of units sold, and each unit contributes 8 units of value, the expression 8x would represent the total value contributed by all units combined.
The measure of two supplementary angles are x+10 and 2x-5. Find the values of x and then find the angles
Answer:
68 1/3, 111 2/3
Step-by-step explanation:
The sum of two supplementary angles is 180°, so ...
(x +10) +(2x -5) = 180
3x +5 = 180 . . . . . collect terms
x +5/3 = 60 . . . . . divide by 3
x = 58 1/3 . . . . . . . subtract 5/3
The first angle is ...
x +10 = 58 1/3 +10 = 68 1/3
The second angle is ...
2x -5 = 2(58 1/3) -5 = 116 2/3 -5 = 111 2/3
The angles measure 68 1/3 and 111 2/3.
Write a linear equation that passes through the point (2,-9) and has a slope of -5
Answer:
y=-5x+1
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=-5(x-2)
y+9=-5x+10
y=-5x+10-9
y=-5x+1
The linear equation that passes through the point (2, -9) with a slope of -5 is y = -5x + 1.
To find the linear equation, we use the point-slope form of a line, which is:
y - y₁ = m(x - x₁)
Here,
m is the slope and (x₁, y₁) is a point on the line.
Given:
Slope (m): -5Point (x₁, y₁): (2, -9)Substitute the values into the point-slope form equation:
y - (-9) = -5(x - 2)
Simplify the equation:
y + 9 = -5(x - 2)y + 9 = -5x + 10y = -5x + 10 - 9y = -5x + 1So, the linear equation in slope-intercept form is y = -5x + 1.

The Murphy family is on a road trip. On the first day, they traveled 30% of their total distance. On the second day, they traveled another 1/4 of the total distance. What fraction of the total distance do they have left after the second day? What percent? ANSWER ASAP!
Answer:
[tex] \frac{11}{20} [/tex]
On the first day, they traveled 30 percents of the total distance. On the second day they traveled one fourth of the total distance. One fourth converted into percentage is 25 percent. Then you add 30 plus 25 because that is the to a
total distance that Murphy's family traveled for 2 days. It will be 55 percents, and you convert 55 percents into fraction will be 55/100, and you simplify it, will be 11/20.

The area of a rectangle is 56 cm. The length is 2 cm more than x and the width is 5 cm less than
twice x. Solve for x. Round to the nearest whole number.
Answer:
x = 6, length = 8 cm and width = 7 cm
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Area of a rectangle = 56 cm²
Length of the rectangle = x + 2
Width of the rectangle= 2x - 5
2. Solve for x. Round to the nearest whole number.
Area of a rectangle = Length * Width
(x + 2) (2x - 5) = 56
2x² + 4x - 5x -10 = 56
2x² - x - 66 = 0
Factoring, we have:
(2x + 11) * (x - 6) = 0
x₁ = 2x + 11 = 0 ⇒ 2x = -11; x₁ = - 5.5
x₂ = x - 6 = 0 ⇒ x₂ = 6
We picked x₂ because x₁ will give us negative values for length and width.
Length = 6 + 2 = 8 cm
Width = 2 * 6 - 5 = 12 - 5 = 7 cm

When writing numbers using scientific notation you always want just one number to the left of the decimal point. When adding a decimal we put it right after the 5 because then we only have one number in front of the decimal point. Then you would go times 10 to the whatever power it is. In our case it was 12 because you go from your decimal point and count backwards til you get to the correct number that you want
