Answer:
The two triangles formed are also similar to each other. The measure of the altitude drawn from the vertex of the right angle to the hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.
Step-by-step explanation:
If you know that a < b, and both a and b and positive numbers, then what just be true about the relationship between the opposites of these numbers? Explain.
Answer:
-a > -b
Step-by-step explanation:
On a number line, every number (except zero, the origin) has both a magnitude and a direction (left or right, negative or positive).
The magnitude is how far the number is from the origin. 10 is further from zero than 6 is. And -10 is alos further from zero than -6 is.
If a < b and a,b are both positive, that means a and b are both on the right-hand side of the number line, and a is closer to the origin than b. The magnitude of a is smaller than that of b.
So if we switch the sign son both a and b, they both become negative and go over to the left-hand side of the number line. But their magntidues do not change, so a is still closer to the origin than b. Since b is now a negative number, further to the left than a, it is smaller than a.
Example: let a = 3 and b =5.
It is true that 3 < 5.
But it is NOT true that -3 < -5. It's the other way around!
-5 < -3
So, if a < b, then -a > -b.

Find m\angle Am∠Am, angle, A.
Round to the nearest degree.
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA = [tex]\frac{-169+136}{120}[/tex]
cosA = -0.275
A = [tex]\text{cos}^{-1}(-0.275)[/tex]
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.
Convert each of mixed number to an improper fraction
Answer:
Top, a through d:
A) 23/8
B) 29/6
C) 23/3
D) 16/5
Step-by-step explanation:
To make the proper fraction improper, first, multiply the whole number by the bottom number in the fraction, then add whatever number was on top of the fraction, so for A, multiply 2 (whole number) by 8 (number on the bottom of the fraction), then add 7 (number on top of the fraction)

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y = 2x - 3
Now, putting x=0
y= -3
and, x= 1
y= 2(1)-3
y = -1
and, x= 2
y=2 (2)- 3
y = 1
Hence, the coordinates of line is (0, -3), (1, -1) and (2, 1)

18 The sides of an isosceles triangle are measured correct to the nearest millimetre.
One side has a length of 8.2 cm and another has a length of 9.4 cm.
Find the largest possible value of the perimeter of this triangle.
Answer:
Step-by-step explanation:
largest perimeter=9.4+9.4+8.2=27.0 cm
or it can be one side=82.4 mm
other sides =94.4 mm
largest perimeter=94.4+94.4+82.4=271.2 mm=27.12 cm

Answer: 32 sq.cm
Step-by-step explanation:
If you think of it as there being 2 squares instead of 1, you can think well since the whole one side of the rectangle is 8cm and the half side is 4 then that must mean that the other square that you just divided up must be 3 by 4 so then you can multiply those and get 12 and you do the same for the other one which would be 4 by 5 and when you multiply those you will get 20 and when added you get 32.

For a normal distribution, what z-score value separates the lowest 25% of the scores from the rest of the distribution
Answer:
Z = -0.675.
Step-by-step explanation:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
What z-score value separates the lowest 25% of the scores from the rest of the distribution
This is Z which has a pvalue of 0.75, so Z = -0.675.
How many square feet of outdoor carpet will

?
3 ft
Ift
2 ft
4 ft
2 ft
12 ft
Answer:
40 sq feet
Step-by-step explanation:
(im bad at explaining)
1 x 2 = 2 sq ft
3 x 2 = 6 sq ft
4 x 12 = 48 sq ft
2 sq ft + 6 + sq ft = 8 sq ft
48 - 8 = 40
The amount of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle) = 40 ft².
What is the Area of a Rectangle?Area of a rectangle = lenght × width.
The amount of square feet of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)
The amount of square feet of outdoor carpet needed = 12 × 4 - (3 × 2 + 2 × 1)

90 divided by 3 + ( 3 - 2 ) - 20.
Answer:
11
Step-by-step explanation:
first 3-2=1 the divide 90 by 3 then add the 1 the subtract that by 20 and you will get 11
The result of the expression 90 divided by 3 plus the quantity (3 minus 2) minus 20 is 11.
To evaluate the expression 90 divided by 3 + (3 - 2) - 20, we can follow the order of operations (also known as PEMDAS/BODMAS), which stands for Parentheses/Brackets, Order/Exponents, Division/Multiplication, and Addition/Subtraction:
First, let's simplify the expression within the parentheses:
3 - 2 = 1
Now we can substitute the simplified expression back into the main expression:
90 ÷ 3 + 1 - 20
Next, perform the division:
90 ÷ 3 = 30
Now we have:
30 + 1 - 20
Next, perform the addition:
30 + 1 = 31
Finally, perform the subtraction:
31 - 20 = 11
Therefore, the value of the expression 90 divided by 3 + (3 - 2) - 20 is 11.
