If 16 pizzas cost $84.80, how much will 12 pizzas cost in dollars?

Answer:

\(r=0.07\)

Step-by-step explanation:

From the question we are told that

An offer of 2$ in 11 years on every dollar

Generally we make use of this formula

\(F=P(1+r/100)^t\)

where

\(f=Future value\)

\(P= present value\)

\(r=Rate\)

\(t=time\)

Mathematically solving  for the rate

     \(2=1(1+r/100)^1^1\)

    \((2)^1^/^1^1=(1+r/100)\)

    \((1+r/100=1.0650\)

     \(r=(1.0650-1) *100\)

     \(r=0.07\)

Generally this shows that the account give an annual rate of 0.07

The linear function for the cost is given as follows:

C(t) = 10 + 3t.

The slope-intercept equation for a linear function is presented as follows:

y = mx + b

In which:

We have that each hour, the cost increases by $3, hence the slope m is given as follows:

m = 3.

For a time of 0 hours, the cost is of $10, hence the intercept b is given as follows:

b = 10.

Thus the function is given as follows:

C(t) = 10 + 3t.

The length of the diagonal of the rectangle is 41 units.

To find the length of a diagonal of a rectangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse).

In this case, the rectangle is the right triangle, and the lengths of the two shorter sides are 9 and 40 units. So we can write the equation:

9² + 40² = d²

Expanding both sides:

81 + 1600 = d²

Adding the two sides:

1681 = d²

Taking the square root of both sides:

d = 41 units

So the length of the diagonal of the rectangle is 41 units.

Answer:

13.8cm

Step-by-step explanation:

formula

b x h / 2

6.9 x 4 / 2

= 13.8

Step-by-step explanation:

initally dose was 250 mg and then increased to 500 mg.

so, percent increase would be :-

(500-250)/250 * 100

= 1 %

so I guess u are correct.

The percentage increase in the size of the dosa is 100%

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, the size of the dosa is increased from 250 to 500.

The amount of increment is:

500 - 250

= 250

The percentage change is given by:

(250/250) × 100%

= 100%

Hence, the percentage increase in the size of the dosa is 100%

The p -value for the hypothesis test is; 0.4195

Let us first define the hypotheses.

We are told that the mean of u.s. college students in general, is estimated to be 4.73. Thus;

Null Hypothesis; H₀: μ = 4.73

Alternative Hypothesis; Hₐ: μ ≠ 4.73

Since we have the standard deviation for the sample, we will use the t-distribution with the formula;

t = (x' - μ)/(s/√n)

Where;

x' is the sample mean.

μ is the value tested at the null hypothesis.

s is the standard deviation of the sample.

n is the sample size.

We are given;

x' = 5.11

μ = 4.73

s = 3.98

n = 52

Thus;

t = (5.11 - 4.73)/(3.98/√52)

t = 0.688

Using a t-distribution calculator, this p-value is 0.4195

Therefore, the inequality |2y−3|−3>0 has a solution for all real numbers y.

Given inequality is |2y−3|−3>0.Rewriting the inequality in standard form:

To rewrite the inequality |2y - 3| - 3 > 0 in standard form, we first need to eliminate the absolute value. To do this, we can split the inequality into two separate cases:

Case 1: 2y - 3 > 0

In this case, we have 2y - 3 - 3 > 0, which simplifies to 2y - 6 > 0. Adding 6 to both sides gives 2y > 6, and dividing by 2 results in y > 3.

Case 2: -(2y - 3) - 3 > 0

Here, we have -2y + 3 - 3 > 0, which simplifies to -2y > 0. Dividing by -2 and reversing the inequality gives y < 0.

Therefore, the solution to the inequality |2y - 3| - 3 > 0 is y < 0 or y > 3.|2y − 3| > 3Multiplying both sides by -1 we get:-|2y − 3| < -3Multiplying by -1 reverses the inequality.|2y − 3| < 3Since the absolute value of a quantity can not be negative, the inequality is true for all y.Therefore, the inequality |2y−3|−3>0 has a solution for all real numbers y.

The values of log5, log3, and log19 are not provided, we cannot determine the exact value of log57 without this information.

We can use the logarithm properties to find the value of log57 given that log75 is 0.83.

One of the logarithm properties states that:

log(a * b) = log(a) + log(b)

Using this property, we can express log57 in terms of log75:

log57 = log(5 * 3 * 19)

Now, we can use the fact that log75 is 0.83 to find log5, log3, and log19, and then add them together to get the value of log57:

log57 = log(5 * 3 * 19)

log57 = log5 + log3 + log19

However, since the values of log5, log3, and log19 are not provided, we cannot determine the exact value of log57 without this information.

To find log57 using the given information log75 = 0.83, we can use the change of base formula:  

if log75 = 0.83, then log57 ≈ 0.827. To find log57 using the given information log75 = 0.83, we can use the change of base formula:log_b(a) = log_c(a) / log_c

Here, we want to find log57 (log_7(5)) using the given information log75 (log_5(7)).

We can rewrite the change of base formula as:log_7(5) = log_x(5) / log_x(7)We know that log_5(7) = 0.83,

so we can substitute this value into the equation:log_7(5) = log_x(5) / 0.83

Now we can use any common base, like base 10 or base e, to find the value of log_7(5). Let's use base 10:log_7(5) = log_10(5) / log_10(7)Now

we can calculate the values of log_10(5) and log_10(7) using a calculator:log_10(5) ≈ 0.69897log_10(7) ≈ 0.84510

Now substitute these values back into the equation:log_7(5) = 0.69897 / 0.84510Now divide to get the value of log_7(5):log_7(5) ≈ 0.82706So, if log75 = 0.83, then log57 ≈ 0.827.

The ant will reach the top in 16.67 hours, or approximately 16 hours and 40 minutes

An ant is about to climb a 50-meter tree. In 2 hours, it can climb 5 meters, but it then slips down 1 meter. How long does it take the ant to reach the top?An ant can climb 4 meters in 1 hour since it climbs 5 meters but then slides down 1 meter in 2 hours. Let us assume that it takes the ant n hours to get to the tree's top. We don't understand the precise number of hours, thus we'll use 'n' to represent the number of hours it takes the ant to reach the top of the tree.

The ant climbs 4 meters per hour, thus it climbs 4n meters after n hours.The ant slips down 1 meter each hour, therefore,  it slides down 1n meters after n hours.If the ant climbs 4n meters but slips down 1n meters, it is actually at 3n meters after n hours. Therefore, 3n = 50 since the ant should reach the top of a 50-meter tree.Since 3n = 50, n = 50/3 ≈ 16.67 (to two decimal places). As a result, the ant will reach the top in 16.67 hours, or approximately 16 hours and 40 minutes.

V = 904.77868423386

V = 904.8

I used my calculator's stored version of pi (instead of something like pi = 3.14)

The units "cubic meters" can be abbreviated to m^3 or \(m^3\)

The volume of the given sphere is 904.8 cubic meters. Thus, option B is the answer.

         The volume of a sphere can be calculated using the formula:

V = \(4/3 * \pi * r^3\),

Where V is the volume and r is the radius of the sphere.

\(\pi\) = 3.14

The radius of the sphere (r) = 6m

Plugging in the given radius of 6m into the formula, we get:

V = (4/3) * \(\pi\) * (6^3)

V = 1.333 * \(\pi\) * 216

V = 1.333 * 3.14 * 216

V = 4.1866 * 216

V = 904.8 cubic meters

If you draw a line from the center to either end of 18.8, this will make a right triangle with hypotenuse is x, one side is 4.7, the other side is 18.8/2 = 9.4

so the Pythagorean Theorem states that a^2 + b^2 = c^2

x^2 = 4.7^2 + 9.4^2 = 22.09 + 88.36 = 110.45

x = 10.5
