Answer:      answer is   si - 90w 8y 28y xis 4

Step-by-step explanation:

I'm assuming the "costs 72" is referring to 72 cents.

If so, then this is one way to solve:

(24 inches)/(72 cents) = (49 inches)/(x cents)

24/72 = 49/x

24*x = 72*49

x = 72*49/24

x = 147

It costs 147 cents, aka $1.47, to get 49 inches of wire.

Answer:

Step-by-step explanation:

The mission was of 225 days.

We are informed from the question the percentage of bad days and number of bad days. So, relating the two parts of question will give the number of days explorers were on mission. Let us assume the total number of days of mission be x.

20% × x = 45

Solving the equation now -

20/100x = 45

Shifting 100 to Right Hand Side of the equation as denominator

20x = 45 × 100

Performing multiplication on Right Hand Side of the equation

20x = 4500

Shifting 20 to denominator on Right Hand Side of the equation

x = 4500 ÷ 20

Performing division on Right Hand Side of the equation

x = 225

Hence, explorers were on mission for 225 days.

The dependent variable in a study, also known as the response variable, is affected by the independent variables.

What is a variable?
A variable is a sign and placeholder for any mathematical object (from the Latin variabilis, "changeable") in mathematics. A variable can, for example, represent a number, a vector, a matrix, a function, the argument of a function, a set, or a set's component.

Numerous issues are resolved in a single computation by using variables in algebraic calculations as if they were explicit integers. For instance, by exchanging the variables that represent them in the quadratic formula with the numerical values of the coefficients in any given quadratic equation, the quadratic formula may solve any quadratic equation. A variable in mathematical logic is either a symbol for an undefined term in the theory or an undefined phrase itself (a meta-variable).

The equation of the line having slope = -1 and passing through a point (-3, 5) is y = -x + 2 and graph is given below.

The general equation of a line is y = m × x + c, where m is the slope and c is the y-intercept of the line.

Given slope is equal to -1.

Therefore the equation of the required line is y = (-1) × x + c.

Given that this line passes through the point (-3, 5).

Therefore we have 5 = (-1) × (-3) + c

⇒ 5 = 3 + c

⇒ 5 - 3 = c

⇒ 2 = c

⇒ c = 2

Therefore the y-intercept of the required line in cartesian coordinate form is (0, 2).

Therefore the required equation of the line is y = (-1) × x + 2

⇒ y = -x + 2.

The volume of the spherical dome will be 12.9π cubic feet when the surface area of the dome is 13.924π.

The volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The dome is the shape of a semi-sphere the volume of the dome will be half of the volume of the sphere.

Given that the Reunion Tower in Dallas, Texas, is topped by a spherical dome that has a surface area of approximately 13,924π square feet.

The volume of the dome will be calculated as below:-

SA = 13.924π

2πr² = 13.92π

r = √6.96

r = 2.63 feet

Volume = 2 / 3 πr³

Volume = ( 2 / 3 ) π ( 2.63)³

Volume = 12.24π cubic feet

Therefore, the volume of the spherical dome will be 12.9π cubic feet.

The Red Savina Habanero is hotter than the Thai Pepper with a number of 6. 1 times

A ratio can be defined as the comparison of two or more numbers on the basis of  their sizes in relation to each other.

It also indicates how many times one number contains another.

Given that;

To determine the ratio, we have to divide Red Savina Habanero hotness rating by Thai Pepper  hotness rating

=  4.6 x 10^5 /  7.5 x 10^4

= 6. 1 times

Thus, the Red Savina Habanero is hotter than the Thai Pepper with a number of 6. 1 times

Answer:

C=36

Step-by-step explanation:

Answer:

c = 36

Step-by-step explanation:

so our equation is 21 = 5/6c - 9

first we need to get rid of the 9. in order to do this, we have to do the opposite of the action shown. so in this case, we would add 9 to both sides. we add it to both sides to keep the equation balanced and equal.

adding 9 to 21 gives us 30. so our equation would then be 30 = 5/6c

now we need to get the c by itself. so we divide by 5/6 because in the original equation the 5/6 and the c are being multiplied to each other.

when we devide 5/6c by 5/6, it cancels out. leaving us with c. 30 divided by 5/6 will in turn gives 36. and there is your answer.

An equation is used to show the relationship between numbers and variables. An equation can be linear, quadratic depending on the degree.

Let N(t) represent the number of students after t years, hence:

Since the population has decreased by 100 students every two years:

N(t) = -(100)/2 * t + 350 = -50t + 350

We'll observe that the evaluated expression equals 244 in the next step.

To evaluate an expression, we only need to swap out the variables with the desired values.

When x = 5 x = 5 x=5, you can be asked to "Evaluate 3 x 3x 3x." In the formula 3 x 3x 3x, take note of the proximity of the number 3 to the variable x. This denotes "x times three."

Here, we must assess:

2(s+t)³-6

By substituting them in the formula for t = 2 and s = 3, we obtain:

2(3+2)³- 6

= 2*(5) (5)³ - 6

= 2*125 - 6

= 244

Consequently, the evaluated expression equals 244.

As per kinematic theory, when any object is moving on a rough surface, the friction force will act on the surface. And the friction force is in the opposite direction to the motion of the object.

Using kinematic formulas, the acceleration speed can be calculated:

[tex]v^{2} = u^{2} +2as[/tex]

As per the given data,

The initial speed of the skater [tex](u) = 12m/s[/tex]

The width of the pitch on the rough ice [tex](s) = 7.0 mt[/tex]

The final speed of the skater [tex](v) = 6.0m/s[/tex]

Substituting these values in the kinematic formula, we get

[tex]a = \frac{v^{2}-u^{2} }{2s}[/tex]

[tex]a = \frac{6^{2}-12^{2} }{14}[/tex]

[tex]a=- 7.71 m/s[/tex]

Therefore the calculated acceleration on the rough ice is [tex]-7.71m/s[/tex]

The 95% confidence range for the difference in the percentages of sleep deprived people in California and Oregon is from -0.0015 to 0.0175.

With a 95% confidence level or 0.05 significance level, we may say that this range overlaps 0 and that the proportions are not statistically different. In other words, based on the findings from this sample, the proportion of the CA and OR populations may be equal.

A confidence interval (CI) is a range of estimates for an unknown parameter in frequentist statistics. The 95% confidence level is the most popular, however other levels, such 90% or 99%, are occasionally used when computing confidence intervals. The percentage of related CIs over the long run that include the parameter's actual value is represented by the confidence level. For instance, 95% of all intervals calculated at the 95% level should include the parameter's actual value.
