Solve for x.
x = 1.2 = 3
Enter your answer, as a decimal
There’s nothing you can do about x = 1.2 = 3, because it has two equal signs. You can’t solve an equation that has two equal signs :(
i need the (rate of change____, so the rock is falling___meters per sec) (the initial value,the initial hight)
NEED ANSWER ASAP!! PLEASE AND THANK U SM
Answer:
- 6 m/s
Step-by-step explanation:
The rate of change is a measure of the slope and can be calculated using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 78) and (x₂, y₂ ) = (10, 30) ← 2 points on the line
m = [tex]\frac{30-78}{10-2}[/tex] = [tex]\frac{-48}{8}[/tex] = - 6
Rate of change is - 6 m/s

Un recipiente está lleno de agua. Se extrae un tercio de su capacidad total y luego la cuarta parte del resto. Si finalmente se le agrega un litro, quedan 25 litros de agua en el recipiente. ¿Cuál es la capacidad total del recipiente?
Answer: 48 litros.
Step-by-step explanation:
El recipiente está inicialmente lleno, definamos esta cantidad como X.
Se extrae un tercio, entonces lo que queda en el recipiente son dos tercios de la cantidad inicial, esto es:
(2/3)*X
Luego se extrae (1/4) de esta cantidad, eso quiere decir que queda (3/4) de esta cantidad, entonces lo que queda es:
(3/4)*(2/3)*X = (2/4)*X = (1/2)*X
Luego se agrega un litro, entonces tenemos:
(1/2)*X + 1 L
Sabemos que esta cantidad es igual a 25 L, entonces:
(1/2)*X + 1 L = 25 L
Resolvamos esto para X
(1/2)*X = 25 L - 1 L = 24 L
X = 2*24 L = 48 L
La cantidad que puede contener el contenedor son 48 litros.

if the area of a circle is 98
Answer:
[tex]7 \sqrt{2} [/tex]
Step-by-step explanation:
given : area =98π
we know area of a circle = π r^2
hence
πr^2=98π { cancelling both π }
r^2=98
[tex]r = \sqrt{98} [/tex]
[tex]r = 7 \sqrt{2} [/tex]

When Mr. Davidson preheated his oven, the oven's temperature rose 3 degrees in 1 6 of a minute. At that rate, how much will the oven heat up in 1 minute?
Answer:
18 degrees
Step-by-step explanation:
When Mr. Davidson preheated his oven, the oven's temperature rose 3 degrees in 1/ 6 of a minute. At that rate, how much will the oven heat up in 1 minute?
Solving the above question
1/6 minute = 3 degrees
1 minute = x
Cross y
1/6x = 3 × 1
x = 3 ÷ 1/6
x = 3 × 6
x = 18 degrees
The oven will heat up 18 degrees in 1 minute

In a triangle ABC, AC=24 cm, BC=30 cm, and m∠C=40°. Determine the area of the triangle. Round to nearest square centimeter.
Answer:
The area of the triangle is 231 cm² to the nearest square centimeter
Step-by-step explanation:
We can find the area of a triangle has the lengths of two sides and the measure of the included angle by using the trigonometry
A = [tex]\frac{1}{2}[/tex] × s1 × s2 × sinФ, where
s1 and s2 are the two sides of the triangleФ is the angle included between s1 and s2In ΔABC
∵ AC = 24 cm
∴ s1 = 24
∵ BC = 30 cm
∴ s2 = 30
∵ m∠C = 40°
∴ Ф = 40°
→ By using the rule of the area above
∵ A = [tex]\frac{1}{2}[/tex] × 24 × 30 × sin(40°)
∴ A = 231.4035395 cm²
→ Round it to the nearest square centimeter
∴ A = 231 cm²
∴ The area of the triangle is 231 cm² to the nearest square centimeter

There is a bag with only red marbles and blue marbles. The probability of randomly choosing a blue marble is 2/9 . There are 63 marbles in total in the bag and each is equally likely to be chosen. Work out how many red marbles there must be.
Answer:
49 red marbles
Step-by-step explanation:
There is a bag with only red marbles and blue marbles.
We are told in the question that:
The probability of randomly choosing a blue marble is 2/9 . There are 63 marbles in total in the bag
Hence: since
P(Blue marbles) = 2/9
Hence,
The number of blue marbles = 63 ÷ 9
= 7
Hence:
2 × 7/9 × 7 = 14/63
Hence, the number of blue marbles = 14 blue marbles
The number of red marbles bus calculated as:
63 - 14 blue marbles
= 49 red marbles

Mark earned $13.50 mowing lawns on Saturday. On Sunday, he spent $6.95 when he purchased a movie ticket. He needed to borrow money from a friend to complete his purchase of a snack. How much money did Mark pay for the snack if he owes his friend $5?
Answer:
$11.55
Step-by-step explanation:
He spent 6.95 of the 13.5 which means he has 6.55 left. He then borrows 5 more dollars to buy snacks, so 6.55+5=11.55.
Answer:
$11.55

The air temperature is −12 °C at sunrise and rises 3 °C every hour for several hours. The air temperature after x hours is represented by the function f(x) = 3x − 12. Find the intercepts
Answer:
4 and -12Step-by-step explanation:
The standard form of writing the linear equation of a line is expressed as;
f(x) = mx + c where;
m is the slope
c is the intercept
Given the function f(x) = 3x − 12
x intercept occurs at f(x) = 0
0 = 3x - 12
3x = 12
x = 12/3
x = 4
Hence the x intercept is 4
y intercept occurs at x = 0
f(x) = 3(0) - 12
f(x) = -12
Hence the y intercept is at -12

Answer:
(h*h)(10) is the same as h(10)*h(10). Let's find the value of h(10) first. To do this, replace every x with 10 like so
Step-by-step explanation:
h(x) = 6-x
h(10) = 6-10
h(10) = -4
So,
h(10)*h(10) = (-4)*(-4)
h(10)*h(10) = 16
The final answer is 16

Nadia is asked to find a number such that the difference between five times the number and three less than twice the number is equal to eighteen. Her work and answer are shown below. 5n−(3−2n)5n−3+2n7n−37nn=====181818213 Is Nadia correct? If not, identify and correct her error.
Answer:
Nadia is incorrect, please check explanations for the correction to her work
Step-by-step explanation:
Here, we want to validate the wok of Nadia
Let the number be n
5 times the number is 5 * n = 5n
Difference between 5n and 3 less than twice the number
3 less than twice the number is 2n-3
So it should be 2n-3 ;
The solution is thus;
5n - (2n-3) = 18
5n - 2n + 3 = 18
3n + 3 = 18
3n = 18-3
3n = 15
n = 15/3
n = 5
Answer:
Nadia is incorrect; she did not translate the given information into an equation properly. The first equation should be 5n−(2n−3)=18.

1/5 x 3/4 in simplest form
we need to multiply : 1/5*3/4 multiply 1 by 3 on the tops so we have 3/5*4 5*4=3/20
The [tex]\frac{1}{5} \times \frac{3}{4}[/tex] in simplest form is [tex]\frac{3}{20}[/tex].
Given that,
The one fraction is [tex]\frac{1}{5}[/tex].And, the other fraction is [tex]\frac{3}{4}[/tex].We need to multiply both the fractions and then write in the simplest form.Based on the above information, the calculation is as follows:
[tex]= \frac{1}{5} \times \frac{3}{4}\\\\= \frac{3}{20}[/tex]
Therefore we can conclude that the [tex]\frac{1}{5} \times \frac{3}{4}[/tex] in simplest form is [tex]\frac{3}{20}[/tex].

Answer:
y = ⅔x - 5
Step-by-step explanation:
The line that passes through (-3, -7) will have the same slope (m) as the line, 2x - 3y = 24. This is because if two lines that are parallel to each other would have the same slope.
Rewrite 2x - 3y = 24, in the slope-intercept form, y = mx + b.
Thus:
2x - 3y = 24, rewritten would give us y = ⅔x - 8.
The slope of the line, 2x - 3y = 24, is ⅔.
Thus, the slope of the line that is parallel to 2x - 3y = 24, is also ⅔.
To find the equation, substitute a = -3, b = -7, and m = ⅔ into y - b = m(x - a).
Thus:
y + 7 = ⅔(x + 3)
Rewrite to make the equation in slope-intercept form.
Thus:
y + 7 = ⅔(x + 3)
3(y + 7) = 2(x + 3) ---› multiplication property of equality
3y + 21 = 2x + 6 ----› distributive property
3y = 2x + 6 - 21 ----› subtraction property of equality
3y = 2x - 15
y = ⅔x - 5 (division property of equality)
