Answer:

5.1

Step-by-step explanation:

The range of a set is found by subtracting the smallest number from the largest.

Here, the largest number is 7 and the smallest is 1.9, so

range = 7 minus 1.9 = 5.1

PIT_PIT [12445]

Answer:

$9 for 36

Step-by-step explanation:

To find the unit price, divide the total cost by the number of items. Here are the costs per item for each option:

1. $0.54

2. $0.43

3. $0.31

4. $0.28

5. $0.25

The best deal is $9 for 36 pens as it results in the lowest price of $0.25 per pen.

The most important component of a physical structure is a solid foundation on which the rest of the structure sits. A strong fou
tester [12383]

Answer and explanation:

Algebra revolves around the fundamental idea of using letters known as variables to represent quantities, which allows for solving for unknown values. Essentially, algebra involves transitioning from what is known to what is unknown to ascertain those unknown results. For instance, if we know a specific item was purchased twice but we're unsure of its price, we can denote this unknown price as 2a or 2p, depending on the selected variable. If the total spending for those items is, say, $50, we can set up the equation 2a = $50, which leads us to find that the cost per item is $25.

Algebra can also manifest itself in expressions, commonly referred to as algebraic expressions, which can be incorporated into equations, such as the previously mentioned 2a = $50. These expressions may take forms like 2a + 3b, where a and b designate the costs of different products that were acquired in quantities of 2 and 3, respectively.

A CAT scan produces equally spaced cross-sectional views of a human organ that provide information about the organ otherwise obt
zzz [12365]
1,107 cc The scanning consists of 10 intervals: [0,1.5), [1.5,3), [3,4.5), [4.5,6), [6,7.5), [7.5,9), [9,10.5), [10.5,12), [12,13.5), [13.5,15) To estimate the volume using the Midpoint Rule, n should be set to 10. Given that we will use n=5, we will split the range [0,15] into five intervals of lengths 3 each: [0,3], [3,6], [6,9], [9,12], [12,15] and calculate their midpoints: 1.5, 4.5, 7.5, 10.5, and 13.5. Next, we will determine the volume V from the five cylinders, where each has a height h=3 and the base area A corresponds to the calculated midpoints' intervals: Cylinder 1 Midpoint=1.5, corresponding to the 2nd interval A = 18, V= height * area of the base = 18*3 = 54 cc Cylinder 2 Midpoint=4.5, corresponding to the 4th interval A = 78, V= height * area of the base = 78*3 = 234 cc Cylinder 3 Midpoint=7.5, corresponding to the 6th interval A = 106, V= height * area of the base = 106*3 = 318 cc Cylinder 4 Midpoint=10.5, corresponding to the 8th interval A = 129, V= height * area of the base = 129*3 = 387 cc Cylinder 5 Midpoint=13.5, corresponding to the 10th interval A = 38, V= height * area of the base = 38*3 = 114 cc Thus, the estimated volume is 54 + 234 + 318 + 387 + 114 = 1,107

Beth drives 200 miles in 4 hours. She drives the first 18 miles at an average speed of 36 mph. Work out her average speed for th
Zina [12379]

Beth travelled the remaining distance with an average speed of 52 mph

Solution:

Given, Beth drives 200 miles in 4 hours.  

The equation for distance speed is expressed as:

\text { distance }=\text { speed } \times \text { time. }   --- eqn 1

Calculating time spent for 18 miles:

She completes the initial 18 miles at an average speed of 36 mph.  

Distance here equals 18 miles

speed equals 36 mph

Substituting values into eqn 1 yields,

\begin{array}{l}{\rightarrow 18 \text { miles }=36 \mathrm{mph} \times \text { time }} \\\\ {\rightarrow \text { time }=\frac{1}{2} \text { hour }}\end{array}

Determining average speed for the remaining journey:

The distance left to cover is = 200 miles – 18 miles = 182 miles

The time spent on the remaining trip equals the total time minus the duration for the first 18 miles

4 \text { hours }-\frac{1}{2} \text { hours }=\frac{7}{2} \text { hours }

Inserting values into eqn 1 gives us

\begin{array}{l}{182 \text { miles }=\text { average speed } \times \frac{7}{2} \text { hours }} \\\\ {\text { Average speed }=\frac{182}{7} \times 2=52}\end{array}

This confirms that the average speed for the rest of the journey is 52 mph

babunello [11817]
Given that x y is parallel to z w and x z serves as a transversal that crosses both x y and z w, it follows that ∠ x z w equals ∠ z x y, which are alternate interior angles because x y is parallel to z w. Also, v is where x z intersects y w, therefore ∠ x v y is congruent to ∠ z v w due to vertically opposite angles. Consequently, this yields triangle Δ x y v being similar to triangle Δ z w v based on the angle-angle similarity.
