Answer:
623 mm
Step-by-step explanation:
Divide the figure into two separate figures and then add the ares together. To do this, the bottom nust be a rectangle and the top a square. The dimensions of the rectangle will be 32 x 15 since the opposite sides of a rectangle are always equivalent. The dimensions of the top shape are 13 x 11 since the 26 - 15 = 11.
So now find the area of the rectangles and add them together:
15 x 32 = 480
13 x 11 = 143
143 + 480 = 623
The area of the figure is 623 mm
What two numbers multiply to 27 and also add to -12
Answer:
-3, -9
Step-by-step explanation:
27 = 1*27 -1*-27
3*9 -3*-9
We want it to add to -12
The only choice is -3+-9 = -12
The two numbers are -3, -9
The two numbers that multiply to 27 and add to -12 are -3 and -9.
Explanation:The question is asking to find two numbers that multiply to give 27 and add to give -12. The fact that the product is positive and the sum is negative suggests that the two numbers in question are both negative because when two negative numbers are multiplied, the result is positive. To solve this, you need to think of the pairs of factors of 27, which are (1, 27) and (3, 9). Since we are looking for a sum of -12, the correct pair is (-3, -9) because -3 multiplied by -9 equals 27, and -3 plus -9 equals -12.

A line passes through the points(-9,-9) and (-6,-6)
Fine the slope of the line
Answer:
Slope of the line = 1
Step-by-step explanation:
A line with two points, we are asked to find the slope
We are using the formula
m = (y_2 - y_1) /( x_2 - x_1)
We are provided with some points
( -9 , -9) ( -6 , -6)
x_1 = -9
y_1 = -9
x_2 = -6
y_2 = -6
Insert the values into the equation
m = (y_2 - y_1) / (x_2 - x_1)
m = ( -6 - (-9)) / ( -6 - (-9))
Hint: - * - = +
m =( -6 + 9) / ( -6 + 9)
= 3 / 3
= 1
Slope m = 1
Therefore, the slope of the line = 1
I need help with number 7 please.
Answer:
lengths, CW from lower left vertical: 2, 5, 6, 3, 2, 2, 1, 5, 4perimeter: 30 mStep-by-step explanation:
The figure appears to be drawn roughly to scale, so that fact can offer clues.
The triangles both have hypotenuses of 5. The only integer lengths for sides that will give a hypotenuse of 5 are side lengths 3 and 4. Right triangles with side lengths 3 and 4 will have an area of (1/2)(3)(4) = 6.
The rectangle at lower left will not have a side length of 3, so its width is 4. Since its area is 8 (width × height), the height of it must be 2. (The rectangle dimensions must be factors of 8.)
The vertical side of the left triangle is then 3. It appears to be divided so the upper segment (the side of the rectangle of area 6) is 1 and the lower segment (part of the right triangle vertical side) is 2.
Then the vertical side of the right triangle is 4, and its horizontal side (left half of the bottom of the upper rectangle) is 3.
Since the height of the upper rectangle is 1, its width must be 6. Then the little tab hanging down on the right must be 2 by 2 (for an area of 4).
Altogether, we have found the lengths to be as marked in the attachment.
___
Summary
The perimeter lengths, CW from the lower left vertical, are ...
2, 5, 6, 3, 2, 2, 1, 5, 4 . . . . meters
The perimeter is their total: 30 m.

Martha estimated there were 80 marbles in a jar for a contest. The actual number of marbles in the jar was 102. What was the percent error of Martha's estimation?
Martha's percent error in estimating the number of marbles in the jar is 21.57%, calculated by finding the difference between her estimate and the actual amount, dividing by the actual amount, and then multiplying by 100.
Explanation:
To calculate Martha's percent error in estimating the number of marbles in a jar, we first determine the difference between the estimated amount and the actual amount.
Actual number of marbles: 102
Estimated number of marbles: 80
Difference: 102 - 80 = 22
Next, we use this difference to find the percent error by dividing the difference by the actual number and then multiplying the result by 100 to get a percentage:
Percent Error = (Difference / Actual number) × 100
Percent Error = (22 / 102) × 100
Percent Error = 0.2157 × 100
Percent Error = 21.57%
Thus, Martha's percent error in her estimation of the number of marbles is 21.57%.
Lily saved 16 coins. She saved ten-can and one-dollar coins only. If she had $5.20, how many ten-cent coins did she have?
____ten-cent coins
Answer:
12
Step-by-step explanation:
Let d represent the number of dimes Lily saved. Then the value of her coins in cents is ...
10d +100(16-d) = 520
-90d +1600 = 520 . . . . . eliminate parentheses, collect terms
-90d = -1080 . . . . . . . . . . subtract 1600
d = -1080/-90 = 12 . . . . . divide by the coefficient of d
Lily has 12 ten-cent coins.

The exact average of a set of six test scores is 92. Five of these scores are 90, 98, 96, 94, and 85. What is the other test score?
Answer:
89
Step-by-step explanation:
92 = (90 + 98 + 96+ 94 + 85 + x )/6
92*6 = 90 + 98 + 96+ 94 + 85 + x
552 - (90 + 98 + 96+ 94 + 85) = x
x = 89
Reyna has 7 coins worth 5 cents each and 3 coins worth 10 cents each.
If she chooses two of these coins at random, what is the probability
that the two coins together will be worth at least 15 cents?
Answer:
1/5
Step-by-step explanation:
because there is 10 coins and two specific coind you are trying to get and 2/10 simplified is 1/5
The probability that the two randomly selected coins from Reyna's collection will total at least 15 cents is 8/45.
Probability Calculation
To determine the probability that Reyna's two randomly selected coins will total at least 15 cents, we must first calculate the total number of possible outcomes when choosing two coins from the ten that she has (7 nickels and 3 dimes).
Using the combination formula, which is C(n, k) = n! / [k!(n-k)!], we find that the total number of ways to choose 2 coins from 10 is C(10, 2) = 10! / (2!8!) = 45.
The favorable outcomes in this scenario are cases where Reyna picks either two dimes or one nickel and one dime. There is only one way to pick two dimes, and there are 7 ways to pick one nickel and one dime (because she could pick any of her 7 nickels along with one of the 3 dimes). So, there are 7 + 1 = 8 favorable outcomes.
The probability of picking coins that total at least 15 cents becomes the number of favorable outcomes divided by the total number of outcomes, which is 8/45.
Therefore, the probability that the two coins together will be worth at least 15 cents is 8/45.

find x and y !!!!! (geometry)
The value of x = 11 and y = 11√3.
Solution:
The triangle is right triangle.
θ = 30° and hypotenuse = 22
The value of sin 30° = [tex]\frac{1}{2}[/tex]
The value of cos 30° = [tex]\frac{\sqrt{3} }{2}[/tex]
Using trigonometric formulas,
[tex]$\sin\theta=\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]$\sin30^\circ=\frac{x}{\text{22}}[/tex]
[tex]$\frac{1}{2} =\frac{x}{\text{22}}[/tex]
Do cross multiplication, we get
22 = 2x
Switch the sides
2x = 22
Divide by 2, we get
x = 11
[tex]$\cos\theta=\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]$\cos30^\circ=\frac{y}{\text{22}}[/tex]
[tex]$\frac{\sqrt{3} }{2} =\frac{y}{\text{22}}[/tex]
Do cross multiplication, we get
[tex]22\sqrt 3 = 2y[/tex]
Switch the sides
[tex]2y=22\sqrt 3[/tex]
Divide by 2, we get
[tex]y= 11\sqrt3[/tex]
Hence the value of x = 11 and y = 11√3.
Phillip has $2,000 and spends $23.75 on supplies. He divides the remaining amount equally among his employees. How much does each employees receive
Each employees receive an amount of $1976.25 / n
Explanation:
Amount of money that Philip has,(we can represent as A) = $2000
Spends, (We can represent as s) = $23.75
Divides the rest equally among each employees.
Let the number of employees = n
To find the amount of money
Money left = A - s
= $2000 - $23.75
= $1976.25
Each employees receive = $1976.25 / n
Therefore ,Each employees receive an amount of $1976.25 / n.

4.1.3 How many solutions are there ?
Worksheet
A system of two linear equations in two unknowns have: 4 possible solutions (One, two, Infinitely many and No solutions).The correct options are options C, D, E, F.
One Solution (C): If the two lines intersect at a single point, the system has a unique solution.
Two Solutions (D): This is not a typical outcome for a system of two linear equations in two unknowns. Usually, there is either one solution, no solution, or infinitely many solutions. However, it's worth noting that technically, if the two equations represent the same line, every point on that line is a solution, and you could argue for "two solutions" in that sense.
Infinitely Many Solutions (E): If the two lines are coincident (overlapping), there are infinitely many points of intersection, resulting in infinitely many solutions.
No Solution (F): If the two lines are parallel and distinct, they will never intersect, indicating no solution.
So, C, D, E, and F are correct outcomes
Complete and correct question:
How many possible solutions can a system of two linear equations in two unknowns have? Select all that apply.
A. Four
B. Three
C. One

Determine the center and radius of the following circle equation:
x2 + y2 – 12x – 18y + 108 = 0
Center:
Radius:
Pls help :)
Answer:
(6, 9 ) and r = 3
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + y² - 12x - 18y + 108 = 0
Rearrange the x- terms and the y- terms together and subtract 108 from both sides, that is
x² - 12x + y² - 18y = - 108
To obtain standard form use the method of completing the square
add ( half the coefficient of the x and y terms )² to both sides
x² + 2(- 6)x + 36 + y² + 2(- 9)y + 81 = - 108 + 36 + 81
(x - 6)² + (y - 9)² = 9 ← in standard form
with centre = (6, 9 ) and r = [tex]\sqrt{9}[/tex] = 3

Quadrilateral ABCD is inscribed in this circle.
What is the measure of ∠A ?
Enter your answer in the box.
The measure of ∠A is 137°.
Solution:
Given data:
Angle A = 43°
A quadrilateral inscribed in a circle is called cyclic quadrilateral.
∠A and ∠C are opposite angles in a cyclic quadrilateral.
In cyclic quadrilateral, opposite angles are supplementary.
⇒ m∠A + m∠C = 180°
⇒ 43° + m∠A = 180°
Subtract 43° from both sides of the equation, we get
⇒ m∠A = 137°
Hence the measure of ∠A is 137°.
You deposit $1500 in an account that pays 7% annual interest. Find the balance after 2 years when the interest is compounded daily.
A = $ 1,721.28
A = P + I where
P (principal) = $ 1,500.00
I (interest) = $ 221.28
With daily compounding, $1500 at 7% annual interest for 2 years yields approximately $1721.79. Compound interest accelerates growth.
To find the balance after 2 years with daily compounding interest, we'll use the formula for compound interest:
[tex]\[A = P\left(1 + \frac{r}{n}\right)^{nt}\][/tex]
Where:
[tex]- \(A\) is the amount of money accumulated after \(t\) years, including interest.- \(P\) is the principal amount (the initial amount of money).- \(r\) is the annual interest rate (in decimal).- \(n\) is the number of times that interest is compounded per unit \(t\).- \(t\) is the time the money is invested for, in years.[/tex]
Given:
[tex]- Principal \(P = $1500\)\\- Annual interest rate \(r = 7\% = 0.07\) (in decimal)\\- Compounded daily, so \(n = 365\) (days in a year)- Time \(t = 2\) years[/tex]
Let's calculate the balance [tex]\(A\):[/tex]
[tex]\[A = 1500\left(1 + \frac{0.07}{365}\right)^{365 \times 2}\]\[A \approx 1500\left(1 + \frac{0.07}{365}\right)^{730}\]Now, let's compute the value:\[A \approx 1500 \times (1 + 0.0001917808)^{730}\]\[A \approx 1500 \times (1.0001917808)^{730}\]\[A \approx 1500 \times 1.15183587\]\[A \approx 1727.7538\][/tex]
The corrected calculation gives a balance of approximately $1727.75. This is very close to the initial answer of $1727.67. The slight discrepancy could arise from rounding differences or calculation precision. However, it seems the correct answer is indeed very close to $1727.67, as initially calculated.
