Answer:
x = 2.564 ( to 3 dec. places )
Step-by-step explanation:
Using the rule of logarithms
log[tex]x^{n}[/tex] ⇔ n logx
Given
[tex]5^{x}[/tex] = 62 ( take the ln of both sides )
ln[tex]5^{x}[/tex] = ln 62, that is
x ln5 = ln 62 ( divide both sides by ln 5 )
x = [tex]\frac{ln62}{ln5}[/tex] ≈ 2.564

A jar contains three red marbles and five green marbles. A marble is drawn at random and not replaced. A second marble is then drawn from the jar. Find the probability that the first marble is red and the second marble is green.
Answer:
P(red then green) = 5/8 * 3/7 = 15/56
Step-by-step explanation: Since this is a logical "and" case, we have to multiply the separate events' probabilities...thus P(red then green) = 5/8 * 3/7 = 15/56
Answer:
3/28
Step-by-step explanation:
3 red+ 5 green = 8 marbles in the jar
1st marble:
P(red) = number of red/ total = 3/8
We keep the marble
2 red+ 5 green = 7 marbles in the jar
P(green) = number of green/ total = 2/7
P (red,keep,green) = P(red)* P(green) = 3/8*2/7 = 6/56 = 3/28

Andre says 10x + 6 and 5x + 11 are equivalent because they both equal 16 when x is 1. Do you agree with Andre?
Answer:
No, They are not equivalent
Step-by-step explanation:
The two expressions are only said to be equivalent if they are the same regardless of whatever value the variable(s) is.
The variable in this question is x.
To prove this, we equate both expressions:
[tex]10x + 6 = 5x + 11[/tex]
[tex]10x - 5x = 11 - 6\\\\\\5x = 5\\\\\\x = 1[/tex]
This shows that they have the same value ONLY when x is 1.
This is why Andre says that they are equivalent, but they are not.
No, I do not agree with Andre because the two equations 10x + 6 and 5x + 11 are indeed equivalent.
Explanation:No, I do not agree with Andre. Two equations are considered equivalent if they have the same solution for all values of x.
Let's check if 10x + 6 and 5x + 11 are equivalent by substituting x = 1 into both equations:
For 10x + 6: 10(1) + 6 = 10 + 6 = 16
For 5x + 11: 5(1) + 11 = 5 + 11 = 16
We can see that both equations indeed equal 16 when x is 1, so Andre is correct in this case. 10x + 6 and 5x + 11 are equivalent equations.
James’s four-year-old brother is trying to arrange black and yellow Legos in rows. He has 56 yellow Legos and 120 black Legos. He wants to arrange them in rows so that there are either only yellow or only black Legos in each row, and so that each row has the same number of Legos. What is the least number of rows he can make?
Answer:
22
Step-by-step explanation:
The four-year-old brother can arrange the Legos in rows of 8.
Explanation:To find the least number of rows the four-year-old brother can make with the black and yellow Legos, we need to determine the greatest common divisor (GCD) of 56 and 120. The GCD will represent the number of Legos in each row.
To find the GCD, we can use the Euclidean algorithm. Divide the larger number (120) by the smaller number (56). The remainder is 8. Then, divide the smaller number (56) by the remainder (8). The new remainder is 0.
Therefore, the GCD of 56 and 120 is 8. This means that the four-year-old brother can arrange the Legos in rows of 8, with 7 rows of black Legos and 1 row of yellow Legos, or vice versa.

Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
b = the distance from B to C = 4 units = 2 ( watch the scale)
h = the distance from A to C along the x axis =6 units = 3 (watch the scale)
A = 1/2 (2)(3)
A = 3 units^2

You raise $420 during a fundraising event. The amount of money that you raise is 120% of your goal. How much more did you raise than your goal?
9514 1404 393
Answer:
$70
Step-by-step explanation:
The excess amount is 20% of the goal. The given amount is 120% of the goal, so the proportion of the given amount that is excess is ...
(20% of goal)/(120% of goal) = 1/6
Then the excess is (1/6)($420) = $70.
You raised $70 more than the $350 goal.
The original fundraising goal was $350, and since $420 was raised, which is 120% of the goal, $70 more was raised than the goal.
Explanation:To find out how much more was raised than the goal during the fundraising event, start by understanding the percentage given. The $420 raised is 120% of the goal, which means the goal amount represents 100%. To calculate the original goal, you should divide the amount raised by the percentage raised (expressed as a decimal), so you divide 420 by 1.2 (since 120% as a decimal is 1.2).
Now, calculate the goal amount:
420 / 1.2 = $350
Therefore, the original goal was $350. Since the amount raised was $420, we subtract the goal from the amount raised to determine how much more was raised:
420 - 350 = $70.
Thus, the amount raised exceeded the goal by $70.
The probability of rolling a 6 on a biased die is 1/5
Work out the probability of rolling exactly one 6
Answer:
if the probability of a 6 is 1/5, the probability of “not six” is 4/5. The probability of a 6 on the first roll and not on the second is 1/5 x 4/5 = 4/25. The six could come on the second roll so that probability must be doubled. The overall probability of exactly one six is 8/25 or 0.32.

Step-by-step explanation:
x+20+2x-70+x+x+20+x+90
=6x+60
6x+60=720
6x=(720-60)
6x=660
660/6=110
x=110
hope this helps!
Answer:
Step-by-step explanation:
sum of all angles of polygon = (n-2)*180 {n is no of sides}
= (6-2)*180 = 4*180 = 720
90 + 2x-70 + x+20 +x + x+20 + x = 720
Bring like terms together
90 - 70 + 20 + 20 + 2x + x + x + x + x =720
60 + 6x = 720
6x = 720 - 60
6x = 660
x = 660/6
x = 110
Answer correctly, will mark brainliest answer !!!
Answer:
x-6
Step-by-step explanation:
The formula for the area of a rectangle is (l)(w)
x-5(w)=x²-11x+30
To solve, you need to put the quadratic equation into standard form
x-5(w)=(x-5)(x-6)
Divide both sides of the equation by x-5 to isolate the width(basically strike out x-5 on both sides)
the width is x-6
I pretty sure that's the right answer since (x-5)(x-6)=x²-11x+30, but I'm in geometry right now, and I had to go back and re-learn.
What is the probability of a die landing on an even number on the first toss, and then an odd number on the second toss?
Dice- 6 sides
Please help
Answer:
i dotn know sorry
Step-by-step explanation:
and this is why brainly is bad
Answer:
1/4 chance
Step-by-step explanation:
Number of even numbers on a die-3
Number of odd numbers on a die-3
a die has 6 sides,
therefore
1/2 of the numbers on a die are even and 1/2 are odd
so a 3/6 chance (1/2 chance (simplify)) of landing on an even number on the first roll
And a 3/6 chance (1/2 chance (simplify)) of landing on an odd number on the second roll
Multiply the two together and a 9/36 chance of this event or simplified to a 1/4 chance of this event
Complete the steps to find the area of the trapezoid.
Area of rectangle = square units
Area of triangle 1 = square units
Area of triangle 2 = square units
Area of triangle 3 = square units
Area of trapezoid = square units
Answer:
Area of rectangle: 256
Area of triangle 1: 24
Area of triangle 2: 16
Area of triangle 3: 96
Area of trapezoid: 120
Step-by-step explanation:
I just did the question on the thing so Ik I'm right.
-The graph measures by twos. To get the area of the rectangle get the base times height of it. That would be 16x16=256.
-Get base (8) times height (6) of triangle 1 then divide by 2, remember to count the squares by 2 for finding all areas. The formula would be 1/2(b)(h) because dividing by 2 is the same as multiplying times 1/2. Plug it in and (8)(6)=48 then divide by 2 which equals 24.
-Same formula for triangle 2. Plug it in and (8)(4)=32 and divide by 2 and it equals 16.
-Same formula for triangle 3. Plugged in is (12)(16)=192 divide by 2 and it equals 96.
-To find the area of the trapezoid get your rectangle area (256) and subtract all the triangle areas. So 256 - 6 - 16 - 96 = 120.
The area of the given shapes are required.
256 square units
24 square units

A rectangle has a perimeter of 80 inches. Write an equation to represent the area A in terms of width w.
Do I use the perimeter?
Answer:
[tex]A = 40w-w^2[/tex]
Step-by-step explanation:
We are given the following in the question:
Perimeter of rectangle = 80 inches.
Let l be the length and w be the width of rectangle.
Perimeter of rectangle =
[tex]P= 2(l+w)[/tex]
Putting values, we get,
[tex]80 = 2(l+w)\\40 = l+w\\\Rightarrow l = 40 - w[/tex]
Now, we have to find the area of the rectangle in terms of w.
Area of rectangle =
[tex]A = l\times w[/tex]
Putting values, we get
[tex]A = (40-w)w\\A = 40w-w^2[/tex]
is the required expression of area of rectangle in terms of w.
Yes, the perimeter is used to calculate the length of the rectangle in the term of w.
