Answer:

h=2 3/4

Step-by-step explanation:

2 3/4+1/2=

you can convert 1/2 into 2/4 so they have like denominators

2 3/4+2/4= 2 5/4 which is also equal to 3 1/4

let me know if its wrong

Answer:

12 square feet

Step-by-step explanation:

A=Area

b=Base

h=Height

To find the area of an triangle, you use the formula A=1/2bh

you plug in the the area and the height to get:

48=1/2xbx8

you do the maths and you get

b=12

Answer:

Step-by-step explanation:

Neither linear nor exponential functions have a "wiggle" in their graph, so the piece in the region x < 0 is polynomial.

The piece in the interval [0, 3] is concave upward and has increasing slope. It could be polynomial, but is most likely the exponential piece of the function.

For x > 3, the function is linear.

There are no gaps in function value where the transition is made from one piece to another, so the function is continuous.

The function tends upward at the right side of the graph. It tends downward at the left side of the graph. This tells you the sign of the infinity they tend toward matches the sign of the infinity x tends toward.

__

On the interval [0, 3], h(x) is represented by an exponential function.

H(x) is a continuous function.

As x approaches +∞, h(x) approaches +∞.

As x approaches -∞, h(x) approaches -∞.

Answer:

Step-by-step explanation:

Inscribed angle → ∠VXY

(Angle included between two chords meeting at a point on circumference)

Minor arc → (arc VY)

(Arc measuring less than 180° is called as minor arc)

Semicircle → (arc VWX)

(Arc inscribed by the diameter)

m(arc VWX) = 180°

(Semicircle)

m(∠VUW) = 110°

(Central angle subtended by an arc)

Answer:

The answer to the Question is D

Answer:

B, C, D

Step-by-step explanation:

If the sales price is 15% off, then the the price is .85(100-15%) of the price so c is true

this also makes b true. (100-15%) is p-.15

495 x .85 (100-15%)=420.75 so d is true

Answer:

Step-by-step explanation:

total scraps=7+3+5

Red  Orange   Speckeled

  7         3                 5

                               -1

   7                3            4

P1=5/15

[tex]P2(1~red~ or~ 1 ~speckeled)=\frac{7}{14} +\frac{4}{14} =\frac{11}{14} \\P=\frac{5}{15} \times \frac{11}{14} =\frac{11}{42}[/tex]

The terms of a mathematical expression are parts of the expression that are connected with addition or subtraction. The factors in a mathematical expression are parts of the expression that are connected with multiplication.

Step-by-step explanation:

Explanation:

When asking/answering questions like this, a survey is involved. It could be multiple choice or fill in the blank. Multiple choice may be the best way because it's easier to compare data results when you have only a few options. It also gives the computer an easier time too.

We aren't conducting an experiment since the researcher is not directly affecting the people, and instead letting them answer the questions without intervention. Also, note how we don't have two groups of treatment vs control. This is another indication we don't have an experiment.

An observational study is not being done here either. Yes the researcher is observing the survey results, but s/he is not making notes on the individuals before the survey is conducted (ie before the questions are asked). An example of an observational study is having the researcher make a tally of students' hair color. The researcher simply looks at each student, marks the correct tally, and doesn't need to ask the student a question. So you can see that the interactive question/answer portion is not present in an observational study.

The phrasing "random trial" is not a study type. When you hear "random trial" in the news, maybe for a new drug being developed, the news report is implying heavily that an experimental study had been done. This is true with all drug trials. One group is the treatment group that gets the actual drug, while the control group gets a fake drug. The control group thinks they get the actual drug, which is important because if they knew it was fake, then it would invalidate the study. I recommend researching the placebo affect for more information. The two group's results are then computed to see if the drug did in fact cause a change in the subjects or not. You would see this if there's a significant difference between the treatment and control group. Anyway, the "random trial" is not a study type but rather an aspect of an experimental study. It's possible your teacher put this in here to throw off students.

Answer:

27

Step-by-step explanation:

We know the missing angle for the triangle on the left is 63. And that is the same angle reflected to the other side. There is a right angle so its 63 + 90 = 157.

180 - 157 = 27

Answer:

I believe the answer is 166.6 Joules or (if rounding to the nearest whole number) 167 Joules.

Step-by-step explanation:

Here is the formula to find the gravitational potential energy of an object:

U = m * g * h (potential energy equals mass times gravitational acceleration * the height)

The mass is 8.5 kilograms, the height is 2 meters, and Earth's gravitational acceleration is always, no matter the other values or earthly situations, 9.8 m/s.

Now we solve:

8.5 * 9.8 * 2 = 166.6 which is rounded to 167 Joules.

Answer:

107

Step-by-step explanation:

f(x)=7x^(2)-5

f(4) means that x=4

f(4)=7*4^(2)-5

    = 7 * 16 -5

    = 112 -5

    = 107
