Answer:

if b = 8

and h = 6

and if im understanding correctly it is asking B*H/2 that would be 8*6 which is 48 then divided by 2 would be 24  

Step-by-step explanation:

Final answer:

Using the formula A = bh/2 for the area of a triangle, with b as 8 and h as 6, we find that the area A equals 24 square units.

Explanation:

To solve the given problem, we need to apply the formula for the area of a triangle, which is A = bh/2, where 'b' is the base of the triangle and 'h' is the height. Given that b equals 8 and h equals 6, we can substitute these values into the formula to find the area.

A = bh/2

A = (8)(6)/2

A = 48/2

A = 24

Therefore, the area of the triangle when b is 8 and h is 6 is 24 square units.

Final answer:

The expressions 4x and 15 + x are not equivalent as they yield different results for the same value of x.

Explanation:

The expressions 4x and 15 + x are not equivalent. Equivalence between two expressions means that for any value of the variable(s) involved, the expressions yield the same result. To determine if these expressions are equivalent, you can compare them for different values of x. For instance, if x is 1, 4x yields 4, whereas 15 + x yields 16, which are not the same. Thus, we can say that the expressions 4x and 15 + x are not equivalent as they produce different results for the same values of x.

Answer:

B 10.4

Step-by-step explanation:

Using the Pythagorean Theorem with a hypotenuse of 26 cm and one side of 10 cm, the length of the other side is found to be 24 cm. Thus, the correct answer is (D) 24 cm.

In a right-angled triangle, you can use the Pythagorean Theorem to find the length of the missing side.

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse c is equal to the sum of the squares of the lengths of the other two sides a and b:

[tex]\[c^2 = a^2 + b^2\][/tex]

Given that the hypotenuse c is 26 cm and one side a is 10 cm:

[tex]\[26^2 = 10^2 + b^2\]\[676 = 100 + b^2\]\[b^2 = 576\]\[b = 24\][/tex]

Therefore, the length of the other side is 24 cm, and the correct answer is (D) 24 cm.

Answer: I believe the answer to this question is: X= 1/5.

Answer:

20%.

Step-by-step explanation:

That is  (60 - 50) / 50

= 1/5

To convert to a percent we multiply by 100:

Final answer:

To the nearest year, it will take about 6 years for the value of the car to reach $15,500.

Explanation:

To find how long it will take for the value of a car to depreciate to $15,500, we can set up an equation using the formula for exponential decay: V = P[tex](1 - r)^t[/tex], where V is the final value, P is the initial value, r is the depreciation rate, and t is the time in years.

Plugging in the given values, we have 15500 = 24000[tex](1 - 0.0675)^t[/tex]. To solve for t, we can take the logarithm of both sides:

log(15500) = log(24000[tex](1 - 0.0675)^t)[/tex]

t * log(1 - 0.0675) = log(15500/24000)

t = log(15500/24000) / log(1 - 0.0675)

Using a calculator, we find that t is approximately 5.54 years. Rounding to the nearest year, it will take about 6 years for the value of the car to reach $15,500.

A. Puritans

Remember, King James was Catholic (brought up presbyetirian) and later enforced Anglican

A) Puritans settled in America to escape religious persecution.

Emigration is the act of leaving one's country or region to live in another. It is a type of migration, which refers to the movement of people from one place to another. Emigration is different from immigration, which is the process of entering a new country or region to live there permanently.

The Puritans were a group of English Protestants in the 16th and 17th centuries who sought to "purify" the Church of England from what they saw as Roman Catholic practices.

They faced persecution and discrimination in England, which led many of them to emigrate to America in search of religious freedom.

The most well-known group of Puritan emigrants to America were the Pilgrims, who established the Plymouth Colony in Massachusetts in 1620.

I'm assuming the equation is:

v = -2000t + 20,000     because the value of a car decreases with time

v = worth of the car

t = number of years

Since you know the value of v = 10,000, substitute or plug in 10,000 for v in order to find t

v = -2000t + 20,000  Substitute 10,000 into v  [To find t, you need to get the variable by itself to one side of the equation.]

10,000 = -2000t + 20,000     Subtract 20,000 on both sides

-10,000 = -2000t    Divide -2000 on both sides to get t by itself [negative divided by a negative results in a positive]

The speed of slower car is 45 mph and faster car is 50 mph.

Step-by-step explanation:

Given,

Distance covered by both cars = 190 miles

Time taken by both of them = 2 hours

Let,

x be the speed of slower car.

Speed of faster car = x+5

Combined speed = x+x+5 = 2x+5

We know that;

Distance = Speed * Time

[tex]190=(2x+5)*2\\190=4x+10\\4x=190-10\\4x=180\\[/tex]

Dividing both sides by 4

[tex]\frac{4x}{4}=\frac{180}{4}\\x=45[/tex]

Speed of slower car = 45 miles per hour

Speed of faster car = 45+5 = 50 miles per hour

The speed of slower car is 45 mph and faster car is 50 mph.

Step-by-step explanation:

We want to find the equation of the line passing through (3,9) and (6,13).

We determine the slope using:

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

Let:

[tex](x_1=3,y_1=9), (x_2=6,y_2=13)[/tex]

We substitute the points to get:

[tex]m = \frac{13 - 9}{6 - 3} = \frac{4}{3} [/tex]

We now use the formula:

[tex]y-y_1=m(x-x_1)[/tex]

We substitute to get:

[tex]y - 9 = \frac{4}{3} (x - 3)[/tex]

Multiply through by 3 to get;

[tex]3y - 27 = 4(x - 3)[/tex]

We expand further to get:

Answer:

The average cost of each dinner at Dave's party is $5.79.

Step-by-step explanation:

Given:

Dave ordered dinner for a party of 10 people.

Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each.

Now, to find the average cost of each dinner at Dave's party.

So, we get the total amount for the dinner:

Three people ordered the $4.75 chicken dinner.

[tex]4.75\times 3=14.25[/tex]

Two people ordered the $4.95 fish dinner.

[tex]4.95\times 2=9.90[/tex]

Five had the beef dinner at a cost of $6.75.

[tex]6.75\times 5=33.75[/tex]

Total amount of dinner = [tex]14.25+9.90+33.75=\$57.90.[/tex]

Now, to get the average cost of each dinner of 10 people we divide the total amount of dinner by 10:

[tex]57.90\div 10[/tex]

[tex]=\$5.79.[/tex]

Therefore, the average cost of each dinner at Dave's party is $5.79.

Final answer:

To find the average cost per dinner at Dave's party, calculate the total cost of each type of dinner and sum them up to get the total cost. Then, divide the total cost by the number of guests to obtain the average cost. The average cost per dinner is $5.79.

Explanation:

To calculate the average cost of each dinner at Dave's party, first calculate the total cost of all dinners combined by multiplying the number of each type of dinner by its price and then adding up the totals:

Chicken dinner cost: 3 dinners × $4.75 = $14.25

Fish dinner cost: 2 dinners × $4.95 = $9.90

Beef dinner cost: 5 dinners × $6.75 = $33.75

Next, add all the costs together to get the total cost of the dinners:

Total cost = $14.25 + $9.90 + $33.75 = $57.90

Now, divide the total cost by the number of guests to find the average cost per dinner:

Average cost = Total cost ÷ number of guests

Average cost = $57.90 ÷ 10 = $5.79

So, the average cost per dinner at Dave's party is $5.79.
