[tex] 25x { }^{2} + (5x - 3)(2x + 7) - 9[/tex]
Step-by-step explanation:
[tex]5x - 3 \times 7x + 10[/tex]
Answer:
35x² + 29x - 30
Step-by-step explanation:
Given
25x² + (5x - 3)(2x + 7) - 9 ← expand factors using FOIL
= 25x² + 10x² + 29x - 21 - 9 ← collect like terms
= 35x² + 29x - 30

Complete each blank using the given information for a square.
Given:
The side of the square = [tex]9\sqrt{6}[/tex] m
To find:
The diagonal of the square.
Solution:
We know that the diagonal of a square is:
[tex]d=a\sqrt{2}[/tex]
Where, d is the length of diagonal and a is the side of the square.
Putting [tex]a=9\sqrt{6}[/tex], we get
[tex]d=9\sqrt{6}\sqrt{2}[/tex]
[tex]d=9\sqrt{12}[/tex]
[tex]d=9(2\sqrt{3})[/tex]
[tex]d=18\sqrt{3}[/tex]
Therefore, the diagonal of the square is [tex]18\sqrt{3}[/tex] m.
A bag contains 10 marbles. Four of them are red, three blue, two white, and one yellow. A marble is drawn at random. What is the probability that it is not yellow.
Answer:
There is a 9/10 probability that the marble will not be yellow.
Step-by-step explanation:
If there are a total of ten marbles, and there is one yellow marble, there is a
1 yellow marble / 10 total marbles chance of getting a yellow marble. Then subtract it from 10/10 to get the probability of NOT getting a yellow marble.
10/10 - 1/10 = 9/10.
Answer:
9/10

Eva payrolls for on a number cube and the number of cubes roll 24 times then what is a reasonable prediction for the number of successful Rolls
Answer:
The reasonable prediction for successful rolls is 4.
Step-by-step explanation:
Assuming the rolling cube is a fair 6 sided cube, so the probability of success of one roll is given as
[tex]P(Success)=\dfrac{Number\ of\ successful\ events}{Number\ of\ total\ events}[/tex]
[tex]P(Success)=\dfrac{1}{6}[/tex]
The total success is given as
[tex]P(Total\ Success)=P(Success)\times Number\ of\ events[/tex]
For 24 rolls it is given as
[tex]P(Total\ Success)=P(Success)\times Number\ of\ events\\P(Total\ Success)=\dfrac{1}{6}\times 24\\P(Total\ Success)=4[/tex]
So the reasonable prediction for successful rolls is 4.

Pleas helpppp
Answer:
[tex]x = 7 \sqrt{2} [/tex]
Step-by-step explanation:
[tex]sinθ = \frac{opp}{hyp} [/tex]
[tex]sin45° = \frac{7}{x} [/tex]
[tex] \frac{ \sqrt{2} }{2} = \frac{7}{x} [/tex]
Cross multiply:
[tex]( \sqrt{2} )(x) = 7(2)[/tex]
[tex]x = \frac{14}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } [/tex]
[tex]x = \frac{14 \sqrt{2} }{2} [/tex]
[tex]x = 7 \sqrt{2} [/tex]
Graham earns $6 for every crate of oranges he picks.
Lynn earns $5 per hour babysitting.
How many crates of oranges does Graham need to pick to earn the same amount
that Lynn earns for 12 hours of babysitting?
Enter your answer in the box.
Graham needs to pick 10 more oranges to have the same amount I think
Step-by-step explanation:
so first multiply 5 and 12 which is 60
5*12=60
then divide 60 from 6 or 6 from 60
60÷6= 10

[tex]given \: that \: p = {x}^{2} + 4x - 2 \: and \: q = 2x - 1 \: and \: q - p = 2 \: find \: x[/tex]
Answer:
x= -1
Step-by-step explanation:
p= x² +4x -2 -----(1)
q= 2x -1 ------(2)
q -p= 2 -----(3)
Substitute (1) and (2) into (3):
2x -1 -(x² +4x -2)= 2
2x -1 -x² -4x +2= 2 (Expand bracket)
-x² -2x +1=2 (Simplify)
x² +2x +2 -1= 0 (Bring all terms to one side)
x² +2x +1= 0
(x +1)²= 0 (Factorise)
x +1= 0 (Square root both sides)
x= -1 (-1 on both sides)

b. If 3x - 3 and 5x + 7° are the angle of a linear pair, find their measurement the angle
Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°

Mark rides his bike from his house to the closest edge of the park, across the length of the park, and then back home. The distance from his house to the closest edge of the park is 0.9 km and the distance from the far side of the park to his house is 1.6 km. The map shows the path Mark took on his bike. If ∠B = 85° on the map, then use the law of cosines to determine the length of the park in kilometers.
Answer:
The length of the park is approximately 1.77 kilometers
Step-by-step explanation:
The law of cosines is most appropriate when the measures of two sides and the included angle formed n=by the path of motion is known
The given parameters of the question are;
The distance from Mark's house to the edge of the park, a = 0.9 km
The distance from the far side of the park to Mark's house, c = 1.6 km
Whereby the included angle between lines, 'a' and 'c' is the ∠B = 85°, by cosine rule, we have;
b² = a² + c² - 2·a·c·cos(B)
Where;
b = The length of the park in kilometers
By plugging in the known values of 'a', 'b', and 'c', we get;
b² = 0.9² + 1.6² - 2 × 0.9 × 1.6 × cos(85°) ≈ 3.11899146089
∴ b = √(3.11899146089) ≈ 1.76606666377
Therefore, the length of the park, b ≈ 1.77 km.

Approximately, what
is the mean number of books between all the
students, rounded to the nearest tenth?
Answer:
8.7
Step-by-step explanation:
Add up all the books
5 students have 6 books each
3 students have 8 books each and so on
5 * 6 = 30
8*3 =24
9*6 = 54
12*4 = 48
-------------
156 books
Divide by the number of students
156/18 =8.6666666
Round to the nearest tenth
8.7
The average ( or mean) number of books per student is 8.7 books

Answer:
C
Step-by-step explanation:
I did this by graphing the points on paper and then forming an equation from there. Another way is to do to slope equation. The slope equation is: [tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex], so you would just fill it in here. (4+4) (I did PLUS since subtracting a negative is adding a postive number). This equals 8. (0-2) is -2, so 8/-2 is -4x. For the y-intercept, it is already shown in the equation. This is 4 because if x is 0, then that is the y-intercept. So: y=-4x+4.
