Step-by-step explanation:
10 sin A = 3 sin A -7 (subtracting 16 from each side)
10 sin A - 3 sin A = -7 (subtracting 10 sin A from 3 sin A to simplify the equation)
7 sin A = -7 (dividing by 7 to get sin A)
sin A = -1
sin^-1(sin A) = sin^-1(-1) = [tex]\frac{3pi}{2}[/tex] = [tex]-\frac{pi}{2}[/tex](applying the inverse function of sin to cancel sin A to A)
A =[tex]\frac{3pi}{2}[/tex],[tex]-\frac{pi}{2}[/tex]
Use FOIL to multiply.
(3x - 7)(x + 5)
Answer:
3x²+8x-35
Step-by-step explanation:
FOIL stands for:
First -> (3x-7)(x+5)
Outer -> (3x-7)(x+5)
Inner -> (3x-7)(x+5)
Last -> (3x-7)(x+5)
Following FOIL, we get:
(3x-7)(x+5)
(3x)(x)+(3x)(5)+(-7)(x)+(-7)(5)
3x²+15x-7x-35
3x²+8x-35
Therefore, the expanded form is 3x²+8x-35
PLZ ANSWER FAST!!!!! Mr. Miller took a poll of which students in his class have gone to a water park. If 7/9 of his class have visited a water park for a total of 21 students, then how many total students are in Mr. Miller's class?
Answer:
29 students
Step-by-step explanation:
divide by 7 to get 1/9 then multiply by 9 to get total.
Answer:
27
Step-by-step explanation:
Let x be the total number of students. So, turning the words of the problem into an equation, we get:
7/9x = 21,
then, 7x = 189
so, x = 27.

Brandon Brandon Drew the two congruent squares shown he divided one square into 2 congruent triangular parts he divided the other square into 2 congruent rectangular parts
Incomplete question: Options
(a) Each triangular part and each rectangular part represents 1/2 the area of one square.
(b) Each triangular part has an area that is greater than the area of each rectangular part.
(c) Each triangular part and each rectangular part represents 1/4 the area of one square
(d) Each rectangular part has an area that is greater than the area of each triangular part.
See attachment for squares
Answer:
(a) Each triangular part and each rectangular part represents 1/2 the area of one square.
Step-by-step explanation:
Given
See attachment
Required
Which statement is true
Before the division, the area of both squares is:
[tex]Area = l * w[/tex]
After the division:
The area of the triangle is:
[tex]Area = \frac{1}{2} * base * height[/tex]
[tex]A_1 = \frac{1}{2} * l * w[/tex]
Substitute Area for l * w
[tex]A_1 = \frac{1}{2} *Area[/tex]
This equals half the area of the square
The area of the rectangle is:
[tex]Area = length * width[/tex]
The length of the rectangle is now half the length of the original square.
So, we have:
[tex]A_2 = \frac{1}{2} l * w[/tex]
Substitute Area for l * w
[tex]A_2 = \frac{1}{2} *Area[/tex]
From the values of A1 and A2, we can conclude that (a) is true

At a candy store, Jordan bought 2 pounds of jelly beans and 3 pounds of gummy worms for $41. Meanwhile, Isabelle bought 2 pounds of jelly beans and 6 pounds of gummy worms for $68. How much does the candy cost?
Answer:
Cost of a pound of Jelly beans = x = $7
Cost of a pound of Gummy worms = y = $9
Step-by-step explanation:
Let us represent
Cost of a pound of Jelly beans = x
Cost of a pound of Gummy worms = y
At a candy store, Jordan bought 2 pounds of jelly beans and 3 pounds of gummy worms for $41.
2x + 3y = 41....... Equation 1
Meanwhile, Isabelle bought 2 pounds of jelly beans and 6 pounds of gummy worms for $68.
2x + 6y = 68...... Equation 2
Combining Equation 1 and 2 together
2x + 3y = 41....... Equation 1
2x + 6y = 68...... Equation 2
We Subtract Equation 1 from Equation 2, thereby eliminating x
3y = 27
y = 27/3
y = $9
Solving for x
2x + 3y = 41....... Equation 1
2x + 3(9) = 41
2x + 27 = 41
2x = 41 - 27
2x = 14
2x/2 = 14/2
x = $7
Therefore, the cost of each candy =
Cost of a pound of Jelly beans = x = $7
Cost of a pound of Gummy worms = y = $9
Parallelogram L M N O is shown. Diagonals are drawn from point M to point O and from point L to point N and intersect at point P. The length of L M is 22 centimeters and the length of M N is 18 centimeters. What is the perimeter of parallelogram LMNO?
Answer:
80 cm
Step-by-step explanation:
The perimeter of parallelogram LMNO
Is calculated using the formula
Perimeter = 2(a + b)
a = 18 cm
b = 22cm
Perimeter = 2(18 + 22)
= 2(40 cm)
= 80 cm
The perimeter of the parallelogram = 80 cm
Answer:
D. 80 cm

Luke and nabila are playing squash Luke wins twice as many games as nabila they play 18 games how many do each win
Answer:
Luke = 12 games
Naliba = 6 games
Step-by-step explanation:
Luke and naliba are playing squash
Luke wins twice as many games as naliba
They play a total of 18 games
Luke= 2x
naliba = x
2x +x= 18
3x= 18
x= 18/3
x= 6
Luke= 2(6)
= 12
naliba= 6
Hence luke wins 12 games and naliba wins 6 games

3. Una caravana migrante, procedente de Honduras debe recorrer 5 km en 4 días si quiere alcanzar al tren conocido como la Bestia que los conducirá al Norte de México, el primer día debido al intenso calor solo avanzan 1200 metros, el segundo día ya los espera un retén militar pero aun así avanzan 1 2/3 km, el tercer día caminan un kilómetro y medio. Si quieren llegar a tiempo para tomar el tren, ¿Cuánto debe recorrer la caravana el último día? A) 18/29 B) 19/30 C) 20/31 D) 21/32
Answer:
B) 19/30
Step-by-step explanation:
Se deben recorrer 5km en total, en números fraccionarios se recorren:
1er día:
1200m = 1.2km = 6/5km
2do día:
1 + 2/3km = 5/3km
3er día:
1.5km = 3/2km
La suma da:
6/5km + 5/3km + 3/2km = 36/30km + 50/30km + 45/30km = 131/30km.
5km son 150/30km.
150/30km - 131/30km = 19/30 km
La respuesta es:
B) 19/30Simplify [tex]\frac{-4}{m^2+m-12} +\frac{m}{m+4}[/tex]

The volume of a square that is 2 feet on all sides is ?
Answer:
8 cubic feet
Step-by-step explanation:
2*2*2=8
Assuming you are talking about a cube, the volume would be the side^3. In this case you said all sides are 2 feet long then the volume would be:
2^3 ft^3 or 8 cubic feet!
