Notice that in the end, the units of teaspoons will be left. Multiply both sides by 480

3 teaspoons * 480 cookies

=======================            =  X

36 cookies

Notice the cookies cancel

3 teaspoons * 480

Answer:

\(\angle BDA = 72^{\circ}\)

\(\angle DAB = 36^{\circ}\)

\(\angle BDC = 108^{\circ}\)

\(\angle BCD = 36^{\circ}\)

\(\angle DBC = 36^{\circ}\)

Step-by-step explanation:

Given

\(\angle ABD = 72^{\circ}\)  

Required

Determine the missing angles

Since AB = AD, then:

\(\angle ABD = \angle BDA\) --- Base angles of an isosceles triangle

Hence:

\(\angle ABD = \angle BDA = 72^{\circ}\)

\(\angle ABD + \angle BDA + \angle DAB = 180^{\circ}\) --- angles in a triangle

\(72^{\circ} + 72^{\circ} + \angle DAB = 180^{\circ}\)

\(144^{\circ} + \angle DAB = 180^{\circ}\)

Collect Like Terms

\(\angle DAB = 180^{\circ} - 144^{\circ}\)

\(\angle DAB = 36^{\circ}\)

\(\angle BDA + \angle BDC = 180^{\circ}\) --- angle on a straight line

\(72^{\circ} + \angle BDC = 180^{\circ}\)

\(\angle BDC = 180^{\circ} - 72^{\circ}\)

\(\angle BDC = 108^{\circ}\)

Since ABC is isosceles, then:

\(\angle DAB = \angle BCD = 36^{\circ}\) --- base angle of isosceles

\(\angle BCD = 36^{\circ}\)

Lastly:

\(\angle BCD + \angle BDC + \angle DBC = 180^{\circ}\)

\(36^{\circ} + 108^{\circ} + \angle DBC = 180^{\circ}\)

\(\angle DBC = 180^{\circ} - 36^{\circ} - 108^{\circ}\)

\(\angle DBC = 36^{\circ}\)

Answer:

15.6 units (3 s.f.)

Step-by-step explanation:

The distance between 2 points is given by the formula below, where \((x_1, y_1)\) is the first coordinate and \((x_2, y_2)\) is the second coordinate.

\(\boxed{{\text{Distance between 2 points}= \sqrt{(y_1 - y_2)^{2} + (x_1 - x_2)^{2} } }}\)

Using the distance formula above,

distance between A(-3, 1) and B(7, 13)

= \(\sqrt{(13-1)^{2} + [7-(-3)]^{2} } }}\)

= \(\sqrt{12^2+(7+3)^2}\)

= \(\sqrt{244}\)

= 15.6 units (3 s.f.)

The expressions represent the total time of her trip in hours is\(\rm \dfrac{80}{s} + \dfrac{50}{s+10}\).

Given that,

For the first 80 miles of her road trip, Lina travels 10 miles/hour slower than she did for the remaining 50 miles of her trip.

It represents Lina's  speed during the first part of her trip.

We have to determine,

Which expressions represent the total time of her trip in hours?

According to the question,

Let the speed traveled during the first part of the trip be "s".

The formula for calculating the distance is expressed as:

\(\rm Distance = Speed \times Time\)

For the first part of the journey:

Distance = 80 miles

Time = \(\rm t_1\)

And Speed = s

Substitute all the values in the formula,

\(\rm Distance = Speed \times Time\\\\80 = s \times t_1\\\\ t_1= \dfrac{80}{s}\)

For the second part of the trip;

Distance traveled = 50 miles

Speed = s + 10 (10miles/hour faster than the first part of the trip)

time = \(\rm t_2\)

Substitute all the values in the formula,

\(\rm Distance = Speed \times Time\\\\50 = (s+10) \times t_2\\\\ t_2 = \dfrac{50}{s+10}\)

Therefore,

Adding both the time to represent the total time of her trip in hours,

\(\rm = t_1 +t_2 \\\\ = \dfrac{80}{s} + \dfrac{50}{s+10}\)

Hence, The required expressions represent the total time of her trip in hours is\(\rm \dfrac{80}{s} + \dfrac{50}{s+10}\).

Step-by-step explanation:

The expression \(-2\vec C+6\vec D\) in the ordered pair notation is (16,-16).

The vector components of a vector are represented as the ordered pair of its x and y components.

For example, if a vector has x - component 'a' and y- component 'b' , then the ordered pair notation for the vector is (a, b), where the vector is \(a \vec i+b \vec j\).

Now the vector C has its x- component = -2

y- component of C = -1

Therefore, ordered pair notation of C = (-2, -1)

x- component of D = 2

y-component of D = -3

Therefore, ordered pair notation of D = (2,-3)

So the expression  \(-2\vec C+6\vec D\) = -2 (-2,-1) +6 (2,-3) = (4,2) + (12, -18)

= (16, -16)  in the ordered pair notation.

That is, the vector \(\bold {-2\vec C+6\vec D}\) is a vector with x-component 16 and y-component -16.

The dimensions of the rectangle are 10 feet (length) and 8 feet (width).

To find the dimensions of the rectangle with an area of 80 square feet and a width that is 2 feet less than the length,

follow these steps:

1. Let the length of the rectangle be L feet and the width be W feet.

2. According to the given information, W = L - 2.

3. The area of a rectangle is calculated by multiplying its length and width: Area = L × W.

4. Substitute the given area and the relationship between L and W into the equation: 80 = L × (L - 2).

5. Solve the quadratic equation: 80 = L² - 2L.

6. Rearrange the equation: L² - 2L - 80 = 0.

7. Factor the equation: (L - 10)(L + 8) = 0.

8. Solve for L: L = 10 or L = -8 (since the length cannot be negative, L = 10).

9. Substitute L back into the equation for W: W = 10 - 2 = 8.

So, the dimensions of the rectangle are 10 feet (length) and 8 feet (width).

Answer:

Germany - 90

Step-by-step explanation:

Here are the options to this question

Germany 90

Sweden   78

Japan       63

Canada    75

The appropriate answer should be a multiple of 2, 3, 5, 6, and 9. That is when the number is divided by 2, 3, 5, 6, and 9 it should have a remainder of zero.

90 / 2 = 45

90 / 3 = 30

90 / 5 = 18

90 / 6 = 15

90 / 9 = 10

Thus, the appropriate number is 90

When 78 is divided by 5 and 9, the remainder is not zero

When 63 is divided by 2, 5 and 6, the remainder is not zero

When 75 is divided by 2, 3, 6 and 9, the remainder is not zero

To test whether becoming a new parent is associated with increased stressful experiences, we can conduct a one-sample t-test.

Given:
- Sample size (n) = 49
- Sample mean X = 5.0
- Sample standard deviation (s) = 1.5
- Population mean (μ) = 3.0 (average adult score on the Life Events Inventory)

The null hypothesis (H₀) is that there is no significant difference in the average score for new parents compared to the population mean. The alternative hypothesis (H₁) is that there is a significant increase in the average score for new parents.

Using an alpha level of 0.05, we can find the critical statistic (t_critical) using a t-table or statistical software. The degrees of freedom (df) for this test is n-1 = 48. By looking up the critical value for a one-tailed test with an alpha of 0.05 and 48 degrees of freedom, we can find the t_critical value.

The critical statistic (t_critical) will determine whether we reject or fail to reject the null hypothesis based on our calculated t-value from the sample data.

Step-by-step explanation:

The rate of filling water in the tank is 23450t gallons per hour.

Let's assume that the time taken to fill the tank is t hours.

The volume of water filled into the tank at time t is given by the expression V(t) = 23450t.

The tank is originally empty, which means its volume = 0 gallons.

After 5 hours,

t= 5 hours

The volume of water filled in is given by \(V(5) = 23450 * 5= 1,17,250\) gallons of water.

Therefore, 1,17,250 gallons of water are filled in the tank after 5 hours.

If we pick 23 fruits at random, then 7% of the time, their mean weight will be greater than 210.8 grams.

To solve this problem, we need to use the Central Limit Theorem, which states that the sampling distribution of the means of a random sample from any population will be approximately normally distributed if the sample size is large enough.

In this case, since we are picking 23 fruits at random, we can assume that the sampling distribution of the mean weight of the fruits will be approximately normal with a mean of 204 grams and a standard deviation of 16/sqrt(23) grams.

To find the weight of the fruits such that their mean weight will be greater than a certain amount 7% of the time, we need to find the z-score associated with that probability using a standard normal distribution table. The z-score can be calculated as:

z = invNorm(0.93) = 1.475

where invNorm is the inverse normal function. This means that the weight of the fruits such that their mean weight will be greater than this amount 7% of the time is:

x = 204 + 1.475*(16/sqrt(23)) = 210.8 grams (rounded to one decimal place)
