Answer:
Step-by-step explanation:
The quadratic formula allows us to solve any quadratic equation that's in the form ax^2 + bx + c = 0.
(The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .)

Step-by-step explanation:
The perimeter of a right -angled triangle is 72 cm . Its side are in the ratio 3 : 4: 5.Work out the longest length of the triangle.
Answer:
The longest length is 30 cm
Step-by-step explanation:
Mathematically, the perimeter of a triangle is simply the sum of the lengths of its three sides
So, what we have to do here is divide the perimeter in the given ratio to get the side lengths
since 5 is the biggest of the numbers in the ratio, it represents the largest length value
so we have this as;
(3 + 4 + 5) = 12
So that would be;
5/12 * 72
= 5 * 6 = 30

what is the value of x?
Answer:
9
Step-by-step explanation:
Answer:
6x+16+20=90
6x+36=180
6x=180-36
6x=144
x=144/6
x=26°
Y=3x-2 y-2=x what is the soultions between the two equations
Answer:
(2, 4)
Step-by-step explanation:
"What is the solution of this system of equations?"
Substitute 3x - 2 for y in the second equation, obtaining:
3x - 2 - 2 = x
Consolidate like terms: subtract x from both sides and add 4 to both sides:
2x = 4. Thus, x = 2. Substituting 2 for x in the first equation, we get:
y = 3(2) -2 = 4.
Thus, the solution is (2, 4)
PLEASEEE HELPPP its due in 10 mins PLSSS
Answer:
About 525 times.
Step-by-step explanation:
You have a 5 in 8 chance of getting a consonant originally. You should try to find an equal ratio except with 840 as the second number. As of now it's 5/8 = ?/840
8 is a factor of 840 and if you divide 840 by 8 you get 105. If you actually think about it 105/840 would be an equal ratio to 1/8 so you multiply 108 by 5 to get 525.

Answer:
y=4.47 and x=√10
Step-by-step explanation:
180°-45°-90°=45°
√10/(sin 45°)=y/(sin 90)
y=4.47
√10/(sin 45°)=x/(sin45)
x=√10

In a child’s bank are 11 coins that have a value of $1.85. The coins are either quarters or dimes. How many coins are quarters?
Answer:
The child has 6 dimes and 5 quarters.
Step-by-step explanation:
Let q and d represent the number of quarters and of dimes respectively.
Then q + d = 11 (Equation A), and ($0.25/quarter)q + ($0.10/dime)d = $1.85 (Equation B).
Multiply the 2nd equation by 100 to remove the decimal fractions:
25q + 10d = 185 (Equation C)
Now multiply the 1st equation by -10 to obtain -10q - 10d = -110 (Equation D), and combine this result with Equation C:
-10q - 10d = -110
25q + 10d = 185
--------------------------
15q = 75, and so q = 75/15 = 5.
According to Equation A, q + d = 11. Replacing q with 5, we get:
5 + d = 11, and so d = 6.
The child has 6 dimes and 5 quarters.
Answer: The amount of money in quarters is $1.75
Step-by-step explanation: There are 7 quarters. 25c+25c+25c+25c+25c+25c+25c=1.75

Jackson recorded the growth of a plant over 10 weeks. The equation y=0.25x+4 represents the height in inches over the time in weeks. How tall will the plant be after 5 weeks? How tall will it be after 12 weeks? (PLEASE HELP)
Answer:
5.25 inches after 5 wks
7 inches after 12 wks
Step-by-step explanation:
after 5 weeks: y = .25(5) + 4 which is 5.25 inches
after 12 weeks: y = .25(12) + 4 which is 7 inches

Define sedimentary rock.(1 point)
Sedimentary rock is a type of rock that is formed over long periods of time by the transformation of existing rock types. The original rock is subjected to large heats and pressures causing very large changes.
Sedimentary rock is a type of rock formed over long periods of time by the cooling and solidification of molten Earth material.
Sedimentary rock is a type of rock that is formed in a very short period of time by sudden violent volcanic eruptions into the ocean. The hot molten material becomes rock very quickly in the cool water.
Sedimentary rock is a type of rock that is formed over long periods of time by layers of silt building up on the floor of a body of water, which is then subjected to the immense weight of the ocean above it.

Three game tickets and four ride tickets cost $39. Five ride tickets cost $15. All game tickets cost the same and all ride tickets cost the same. What is the ratio of the cost of a game ticket to the cost of a ride ticket?
Answer: 3:1
Step-by-step explanation:
Let the cost of a game ticket be g.
Let the cost of a ride ticket be r.
The information given can be formed into an equation which will be:
3g + 4r = 39
Since Five ride tickets cost $15, the cost of each ride ticket will be:
= $15/5
= $3.
Therefore, 3g + 4r = 39
We put the value of r = $3 into the equation
3g + 4(3) = 39
3g + 12 = 39
3g = 39 - 12
3g = 27
g = 27/3
g = 9
The cost of a game ticket is $9
The ratio of the cost of a game ticket to the cost of a ride ticket will be:
= 9/3
= 3/1
= 3:1
The ratio is 3:1

Choose the ordered pair that is a solution of the system.
x + y = 4
x = –1
A.
(–1, 3)
B.
(5, –1)
C.
(–1, 5)
Answer:
C.
(–1, 5)
Step-by-step explanation:
(− 1 , 5) is a solution of the system because it makes both equations true. The ordered pair, negative 1, 5, is a solution of the system because it makes both equations true.
x + y− 1+54=?⎯⎯⎯⎯=444 X plus y equals 4.Does negative 1 plus 5 equal 4?Negative 4 equals negative 4.
x−1==−1−1 ✔ X equals negative 1.Negative 1 equals negative 1.

Honon spent 3 1/4 hours on homework while Sequoia spent 2 5/6 hours on homework. How much more time did Honon spend on homework than Sequoia
Answer:
5/12 hours
Step-by-step explanation:
Honon = 3 1/4 hours
Sequoia = 2 5/6 hours
How much more time did Honon spend on homework than Sequoia
= number of hours Honon spent - number of hours Sequoia spent
= 3 1/4 hours - 2 5/6 hours
= 13/4 - 17/6
= (39-34) /12
= 5/12 hours
