Answer:
9.6 minutes
9 minutes 36 seconds
Step-by-step explanation:
10/10 = 1
4/10 = 0.4
24 * 0.4 = 9.6
Simplify.(6x−5+4x^2)+(2x−2)
=6x + −5 + 4 x 2 + 2x + −2
=(4 x 2) + (6x + 2x) + (−5 + −2)
=4 x 2 +8x + −7
Answer - 4 x 2 + 8x + −7
Answer:
(6x-5+4x2) + (2x-2)

The value of the prime number which is a factor of 42 and 45 would be 3.
Used a concept of prime number that states,
A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. Numbers that have more than two factors are called composite numbers.
Given that the two numbers are 42 and 45
Now, factors of numbers 42 and 45 are,
The Factor of 42 are
1, 2, 3, 6, 7, 14, 21, 42
And, The factors of 45 are
1, 3, 5, 9, 15, 45

Answer:
I think its 80 not sure
Step-by-step explanation:
The measure of ∠A will be 50°.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Δ ABC ≅ Δ DEF
And, m ∠A = (x + 30)°, m ∠C = 45°, and m ∠D = 80°
Now,
Since, Δ ABC ≅ Δ DEF
Hence, m ∠A = m ∠D
Substitute all the values, we get;
m ∠A = m ∠D
x + 30 = 80
Subtract 30 both side, we get;
x = 80 - 30
x = 50°
Thus, The measure of ∠A will be 50°.

Wildlife conservationists are concerned that the deer population might not be constant across the National Forest. The scientists found that there were 144 deer in a 16-square-mile area of the forest. In another part of the forest, conservationists counted 117 deer in a 13-square-mile area. Yet a third conservationist counted 216 deer in a 24-square-mile plot of the forest. Do conservationists need to be worried? a. Why does it matter if the deer population is not constant in a certain area of the National Forest? b. What is the population density of deer per square mile? The unit rate of deer per 1 square mile is _______. Constant of Proportionality: Explain the meaning of the constant of proportionality in this problem: c. Use the unit rate of deer per square mile (or 푦 푥 ) to determine how many deer there are for every 207 square miles. d. Use the unit rate to determine the number of square miles in which you would find 486 deer.

A foreign country uses the stellar as its currency. Before a trip to that country, Mia wants to exchange $1700 to steller's. Which of Bank A and Bank B has the better exchange rate? How many more steller's would she get if she exchanged her $1700 at the better exchange rate instead of at the other rate?
Answer and explanation:
Stellar is a Brazilian cryptocurrency that is used to facilitate low cost and flexible payment. It was renamed lumens and is denoted XLM.
One stellar lumen is currently equal to $0.219096
For the purpose of the question and since it does not specify exchange rates for each bank, let's assume:
Bank A= 0.219097 to 1 US dollar
Bank B= 0.219099 to 1 US dollar
Using Bank A to exchange $1700 for stellars= $1700*0.219097= 372.464 stellars
Using Bank B to exchange $1700 for stellars= $1700*0.229042= 389.3714 stellars
From the above, we can see that Bank B has a better exchange rate as it is cheaper than Bank A(gives more stellar) . She should therefore use Bank B for her exchange.

what’s the slope of (9,3) and (2,11)
Answer:
slope = - [tex]\frac{8}{7}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (9, 3) and (x₂, y₂ ) = (2, 11)
m = [tex]\frac{11-3}{2-9}[/tex] = [tex]\frac{8}{-7}[/tex] = - [tex]\frac{8}{7}[/tex]
Answer:
[tex]\boxed {m = -\frac{8}{7}}[/tex]
Step-by-step explanation:
Use the Slope Formula to help you determine the slope of two given points:
[tex]m =\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
First point: [tex](x_{1}, y_{1})[/tex]
Second point: [tex](x_{2}, y_{2})[/tex]
-Apply the two given points onto the formula:
First point: [tex](9, 3)[/tex]
Second point: [tex](2, 11)[/tex]
[tex]m =\frac{11 - 3}{2 - 9}[/tex]
-Solve for the slope:
[tex]m =\frac{11 - 3}{2 - 9}[/tex]
[tex]m =\frac{8}{-7}[/tex]
[tex]\boxed {m = -\frac{8}{7}}[/tex]
Therefore, the slope is [tex]-\frac{8}{7}[/tex].

jerry bought 5 candy bars for $14.75. if the king size candy bar cost $3.75 and a regular size candy bar cost $1.75, how much of each candy bar did he buy?
one equation looks like:
3.75x+1.75y=14.75
Answer:
King size(x): 3
Regular size(y): 2
Steps:
System of Equations:
x+y = 5
3.75x+1.75y = 14.75
Multiply 3.75 on all sides.
3.75x+3.75y = 18.75
3.75x+1.75y = 14.75
Subtract top and bottom
2y = 4
/2 /2
y = 2
After you know regular size amount, figure out king size ----3.

Answer:
[tex]y=-\frac{3}{2}x+1[/tex]
Step-by-step explanation:
Slope-intercept form means
[tex]y=mx+c[/tex]
where m is given its the slope which is [tex]-\frac{3}{2}[/tex] and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,
[tex]y=mx+c[/tex]
[tex]-5 = -\frac{3}{2}(4)+c[/tex]
[tex]-5=-6+c[/tex]
[tex]c=1[/tex]
now we know the value of slope which is given [tex]-\frac{3}{2}[/tex] and we found the value of which is 1 so we put these values into our original slope-intercept form equation
[tex]y=mx+c\\\\y=-\frac{3}{2}x+1[/tex]
