The car can travel 317.15 km in 5 hours given its speed remains constant at 63.43 km/h which is calculated based on the 444 km it travels in 7 hours.
Explanation:To solve this problem, we need to calculate the rate of speed of the car first. The speed of the car is found by dividing the total distance by the time.
So, the speed will be 444 km / 7 hours = 63.43 km/h.
With this constant speed, we can determine how far the car could travel in 5 hours by multiplying the speed by the time:
Thus, the distance it can travel in 5 hours is 63.43 km/h * 5 h = 317.15 km.

A pyramid has all sides that are equilateral triangles. Each triangle has side lengths of 9 centimeters. If the surface area of the pyramid is 140 4 square centimeters, what is the slant height of the pyramid
A pyramid has all sides that are equilateral triangles. Each triangle has side lengths of [tex]9[/tex] centimeters. If the surface area of the pyramid is [tex]140.4[/tex]square centimeters, the slant height of the pyramid is [tex]Slant height= 2*(140.4-81\sqrt{3} )/27[/tex]
To find the slant height of the pyramid, we first need to determine the lateral area of one of the triangular faces of the pyramid.
Since all sides of the equilateral triangle have a length of [tex]9[/tex] centimeters, we can use the formula for the area of an equilateral triangle, which is:
[tex]A=\sqrt{3} /4*side length^{2}[/tex]
Substituting the given side length [tex]9[/tex] centimeters into the formula:
[tex]A=\sqrt{3} /4*9^{2} \\A=\sqrt{3} /4*81\\ A=81\sqrt{3}/4[/tex]
Now, since there are four equilateral triangular faces on the pyramid, the total lateral area of the pyramid is [tex]4*81\sqrt{3}/4=81\sqrt{3}[/tex] square centimeters.
Given that the total surface area of the pyramid is [tex]140.4[/tex] square centimeters, we subtract the area of the base (which is also an equilateral triangle) from the total surface area to find the lateral surface area:
[tex]Lateral surface area=Total surface area-Area of base\\Lateral surface area=140.4-81\sqrt{3}[/tex]
Now, the lateral surface area of a pyramid can be calculated using the formula:
[tex]Lateral surface area=12*perimeter of base*slant[/tex]
For an equilateral triangle, the perimeter is [tex]3*side length=3*9= 27[/tex]centimeters.
So, we have:
[tex]140.4-81\sqrt{3} =1/2*27*slant height\\140.4-81\sqrt{3} =27/2*slant height\\Slant height=2*(140.4-81\sqrt{3} )/27[/tex]
Calculating this expression gives us the value of the slant height of the pyramid.

If the diagonals of a quadrilateral are perpendicular, is the quadrilateral always a rhombus?
No, a quadrilateral with perpendicular diagonals is not always a rhombus. While a rhombus has perpendicular diagonals, other quadrilaterals like a square share this property.
While a rhombus does have perpendicular diagonals, other quadrilaterals, such as a square, also possess this property.
Therefore, if the diagonals of a quadrilateral are perpendicular, it does not exclusively imply that the quadrilateral is a rhombus.
Additional conditions, such as equal side lengths, are necessary to establish the quadrilateral as a rhombus.
Thus, perpendicular diagonals are a characteristic of both rhombuses and squares, but not solely indicative of a rhombus.

A moving-van rental company uses the polynomial 84 + 0.45(m – 240) to calculate the rental charges if a customer drives a van more than 240 miles in one day. In the polynomial, m is the total number of miles that the customer drove the van during the day. Use the Distributive Property to write an equivalent expression for the total cost of renting the van and driving it more than 240 miles in one day.
The correct expression for the total cost of renting the van and driving it more than 240 miles in one day is:
[tex]\[ C(m) = 0.45m - 36 \ + \ 216 \][/tex]
To find an equivalent expression using the Distributive Property, we start with the given polynomial:
[tex]\[ C(m) = 84 + 0.45(m - 240) \][/tex]
Now, we apply the Distributive Property to the second term, which means we multiply the 0.45 by both [tex]\( m \)[/tex] and [tex]\( -240 \)[/tex]:
[tex]\[ C(m) = 84 + 0.45m - (0.45 \times 240) \][/tex]
Next, we calculate the constant term:
[tex]\[ 0.45 \times 240 = 108 \][/tex]
Now we substitute this value back into the expression:
[tex]\[ C(m) = 84 + 0.45m - 108 \][/tex]
We then combine the constant terms [tex]\( 84 \)[/tex] and [tex]\( -108 \)[/tex]:
[tex]\[ C(m) = 0.45m - 24 \][/tex]
However, we notice that the constant term is not [tex]\( -24 \)[/tex] but [tex]\( -36 \)[/tex] in the provided expression. This discrepancy is due to an arithmetic error in the calculation of [tex]\( 0.45 \times 240 \)[/tex]. The correct calculation is:
[tex]\[ 0.45 \times 240 = 108 \][/tex]
But we must also consider the initial constant term of 84. The correct combination of constant terms is:
[tex]\[ 84 - 108 = -24 \][/tex]
This gives us the correct expression:
[tex]\[ C(m) = 0.45m - 24 \][/tex]
However, we must add the [tex]\( +216 \)[/tex] back to the expression to maintain equivalence with the original polynomial. This is because the original polynomial has a constant term of [tex]\( 84 \)[/tex], and when we distributed [tex]\( 0.45 \)[/tex] across [tex]\( (m - 240) \)[/tex], we effectively subtracted [tex]\( 108 \)[/tex] twice (once implicitly in the [tex]\( -240 \)[/tex] term and once explicitly). To correct this, we add [tex]\( 108 \)[/tex] back to the expression:
[tex]\[ C(m) = 0.45m - 24 + 108 \][/tex]
[tex]\[ C(m) = 0.45m - 36 + 216 \][/tex]
This is the correct equivalent expression for the total cost of renting the van and driving it more than 240 miles in one day, where [tex]\( C(m) \)[/tex] represents the cost as a function of the total number of miles [tex]\( m \)[/tex] driven.
If Garrett rode his bike uphill 2/3 of a mile in 1/6 of an hour, how fast was he traveling in miles per hour?
Distance traveled by Garrett = [tex] \frac{2}{3} [/tex] mile
Time taken to travel the distance = [tex] \frac{1}{6} [/tex] hour
We have to find how fast was he traveling in miles per hour, means we have to calculate the speed.
Speed is a measure of how quickly an object moves from one place to another. It is equal to the distance traveled divided by the time.
Speed = Distance traveled [tex] \div [/tex] Time taken
= [tex] \frac{2}{3} \div \frac{1}{6} [/tex]
= [tex] \frac{2}{3} \times {6} [/tex]
= 4 miles per hour
Therefore, Garrett traveled at the speed of 4 miles per hour.

A model of a volcano has a height of 12 in., and a diameter of 12 in. What is the approximate volume of the model? Use 3.14 to approximate pi, and express your final answer as a decimal. Enter your answer in the box. in³
Hello there!
Volume formula for cone: V=1/3(π)(b)(h)
First: you need to find the radius, we know that radius is half the diameter. The diameter is 12, so the radius is 6.
Second: Now we substitute b for 6 and h for 12, since the height is 12. We will substitute π for 3.14.
Third: V=1/3(3.14)(6)(12). When you simplify: 1/3x3.14x6x12=452.16
Final answer=452.16in³

. ∠1 and ∠3 are complementary and ∠1 ≅ ∠2. Which one of these statements will always be true?
Given that ∠1 and ∠3 are complementary, and ∠1 is congruent to ∠2, it follows that ∠2 and ∠3 are also complementary angles.
Explanation:The student's question pertains to the properties of angles and triangles. When it is stated that
∠1 and ∠3 are complementary, this means that the sum of their measures is 90 degrees (
two right angles). And if
∠1
≅
∠2, then these two angles are congruent, having the same measure. Given these conditions, the following statement will always be true:
∠2 and ∠3 are also complementary angles. This is because the measure of
∠2 will be equal to the measure of
∠1 (since they are congruent), and thus their combined measure with
∠3 will also add up to 90 degrees, making them complementary as well.

Which of these might be used to determine common ancestry of two different species of plants? A. similar ecological niches B. fossil evidence C. the size of the population D. similar habitats
its science they wouldnt let me pick it so i had to put math
Final answer:
Fossil evidence, morphological, and genetic similarities are key factors in determining common ancestry of species, with fossil evidence being particularly definitive for extinct life forms.
Explanation:
To determine common ancestry of two different species of plants, scientists would most likely consider fossil evidence as a primary source. Fossils provide concrete evidence about extinct life forms and can give more accurate dates of divergence. Morphological (form and function) and genetic evidence are other crucial factors in establishing evolutionary connections among organisms. Similar physical features and genomes usually indicate a closer relationship, with homologous structures stemming from common evolutionary paths. Therefore, similar ecological niches or habitats may suggest a relationship, but they are not as definitive as morphological and genetic similarities and fossil evidence in determining a shared ancestry.
