what is 7/9 x 5 2/5 as a fraction
Answer:
[tex] \frac{7}{9} \times 5 \frac{2}{5} \\ = 4 \frac{1}{5} [/tex]
The result of 7/9 × 5 2/5 as a fraction is 21/5.
What is the simplified form of the expression?Given the expression in the question:
7/9 × 5 2/5
To multiply 7/9 by 5 2/5 as a fraction, first, convert the mixed number 5 2/5 to an improper fraction.
5 2/5 ⇒ ( 5 × 5 + 2 )/5 = ( 25 + 2 )/5 = 27/5
Hence, we have:
7/9 × 27/5
To multiply fractions, multiply the numerators together and then multiply the denominators together:
( 7 × 27 )/( 9 × 5 )
( 189 )/( 9 × 5 )
189/45
Simplifying, we get:
21/5
Therefore, the simplified form is 21/5.

Given the side lengths, determine whether the triangle is acute, right, obtuse, or not a triangle.
15, 16, 21
A Not a Triangle
B Acute
Obtuse
D Right
9514 1404 393
Answer:
B acute
Step-by-step explanation:
We can define a "form factor" for a triangle as ...
f = a² +b² -c²
where c is the longest side length. It will be interpreted as follows:
negative -- obtuse trianglezero -- right trianglepositive -- acute triangleFor this triangle, our "form factor" is ...
f = 15² +16² -21² = 225 +256 -441 = 40 . . . . a positive number
The triangle is Acute.
The weight of adult female panthers in one habitat area are normally distributed with a mean of 82 pounds and a standard deviation of 9.8 pounds. What percent of the panthers weigh less than 76 pounds?
Answer:
27.09% of the panthers weigh less than 76 pounds
Step-by-step explanation:
Normal Probability Distribution:
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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean of 82 pounds and a standard deviation of 9.8 pounds.
This means that [tex]\mu = 82, \sigma = 9.8[/tex]
What percent of the panthers weigh less than 76 pounds?
The proportion is the pvalue of Z when X = 76. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{76 - 82}{9.8}[/tex]
[tex]Z = -0.61[/tex]
[tex]Z = -0.61[/tex] has a pvalue of 0.2709
0.2709*100% = 27.09%
27.09% of the panthers weigh less than 76 pounds
Factorise the following.
Answer:
ii. [tex](a^{2} +b^{2} +2bc+c^{2} )(a+b+c)(a-b-c)[/tex]
v. [tex](x^{2} -y^{2} )^{2}[/tex]
Step-by-step explanation:
ii. [tex]a^{4} -(b+c)^{4}[/tex]
[tex]=(a^{2} )^{2} -((b+c)^{2} )^{2}[/tex] (Rewrite using Exponent Rules)
[tex]=(a^{2} +(b+c)^{2} )(a^{2} -(b+c)^{2} )[/tex] (Difference of Squares)
[tex]=(a^{2} +b^{2} +2bc+c^{2} )(a+(b+c))(a-(b+c))[/tex] (Expand the terms in the first parentheses, use the difference of squares again to further factor the terms in the second parentheses)
[tex]=(a^{2} +b^{2} +2bc+c^{2} )(a+b+c)(a-b-c)[/tex] (Simplify)
v. [tex]x^{4} -2x^{2} y^{2} +y^{4}[/tex]
[tex]=(x^{2})^{2} -2x^{2} y^{2} +(y^{2} )^{2}[/tex] (Rewrite using Exponent Rules, notice that this is now a perfect square trinomial)
[tex]=(x^{2} -y^{2} )^{2}[/tex] (Factor using perfect square trinomial formula)

Question:Find the area of he trapezoid by decomposing it into other shapes.
Answer:
D) 171 cm²
Step-by-step explanation:
You don’t actually need to decompose it. You could just do it as a trapezoid:
(15+23)/2=19
19x9=171
If you want to decompose it into 2 triangles and a rectangle:
10=15x9=135
1/2(3)(9)=13.5
1/2(5)(9)=22.5
135+13.5+22.5=171 also

Answer:
3x - 4y = -4
Step-by-step explanation:
When you put co-ordinate in it then give zero
3(-4)-4(-2)+3=0
3x-4y=-4 equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2).
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation is 3x - 4y = 7
Convert it to slope intercept form
-4y = 7 - 3x
4y=-7+3x
y=-7/4+3/4x
y=3/4x-7/4
3/4 is the slope and the parallel line should also have the same slope.
Now equation of line passing through (-4, -2)
-2=3/4(-4)+b
-2=-3+b
-1=b
So y=3/4x-1
3x-4y=-4 is another equation represents the line which is parallel.
Hence, 3x-4y=-4 equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2).

An elementary school is offering 3 language classes: one in Spanish, one in French, and one in German. These classes are open to any of the 100 students in the school. There are 28 students in the Spanish class, 21 in the French class, and 12 in the German class. There are 9 in both Spanish and French, 5 in both Spanish and German, and 5 that are in both French and German. There are 3 students taking all 3 classes.
Required:
a. If a student is chosen randomly, what is the probability that he or she is not in any of the language classes?
b. If a student is chosen randomly, what is the probability that he or she is taking exactly one language class?
c. If 2 students are chosen randomly, what is the probability that at least 1 is taking a language class?
Answer:
0.55 ; 0.32 ; 0.7
Step-by-step explanation:
Let :
Spanish = S ; French = F ; German = G
SnFnG = 3
(SnF) only = 9 - 3 = 6
(SnG) only = 5 - 3 = 2
(FnG) only = 5 - 3 = 2
S only = 28 - (6+3+2) = 17
F only = 21 - (2+3+2) = 14
G only = 12 - (6+3+2) = 1
Student not taking any of the classes :
(100 - (17+14+1+2+2+6+3))
100 - 45 = 55
A.) P(not taking any language class).
Required outcome = 55
Total possible outcomes = 100
= 55 / 100 = 0.55
B.)
P(taking exactly one language class)
(S only + F only + G only) / 100
(17 + 14 + 1) / 100
= 32/100
= 0.32
C.)
Atleast 1 is taking a language class out of 2 selected
Possibilities :
(taking and not taking) ;
(not taking and taking) ;
(taking and taking)
