PUZZLE: READ THE CLUE BELOW: CLUE 1-THE THOUSANDS DIGIT IS 8 ,WHICH IS TWO MORE THAN THE HUNDREDS DIGIT. CLUE 2- THE UNIT DIGIT IS ONE LESS THAN THE TENS DIGIT. CLUE 3-THE HUNDREDS DIGIT IS DOUBLE THE UNITS DIGIT. WHAT IS THE NUMBER?
Answer:
8,643
Step-by-step explanation:
The thousands digit is 8 so we know it is 8,000 The hundreds digit is 2 less than 8, so it's 6, giving us 8,600. The units digit is half the hundreds digit, so it is half of 6, or 3, now we have 8,603. Lastly, the tens digit is one greater than the units digit, so it is 4, leaving you with 8,643.
What is the value of the angle marked with 2?

Consecutive angles cut by a common transversal are supplementary. That means that
x + 87 =180 Subtract 87 from both sides.
x+87-87=180-87
x = 93
Abigal found that she can drive 140 miles in 3 hours, including rest stops, on intersate highway. How long would it take her to drive the interstates from cleveland, ohio, to washington dc which is 350 miles?
Answer:
7.5 hours
Step-by-step explanation:
distance = rate * time (d=rt)
First we find her average rate, or speed:
140 miles = 3 hours * rr = [tex]\frac{140 miles}{3 hours}[/tex] = 46.6666 miles/hourNow we take that rate and use our second distance to find the time:
d = rt
t = d/r = 350 miles / 46.6666 miles/hour = 7.5 hours

Find the volume of the composite figure below
Answer:
1386 in³
Step-by-step explanation:
Volume of the composite cone = volume of a hemisphere + volume of a cone
=>Find the volume of cone
Volume of cone = ⅓πr²h
π = 3.142
r = 7 in
h = =√(15² - 7²) [using Pythagorean theorem to solve for height given the slant height and radius]
h = √(225 - 49)
h = √176 ≈ 13 in
Volume of cone = ⅓*3.142*7²*13
= ⅓*2001.454 ≈ 667 in³
=>Find volume of hemisphere.
Volume of hemisphere = ½*volume of sphere = ½*4/3πr³ = ⅔πr³
π = 3.142
r = 7 in
Volume = ⅔*3.142*7³ ≈ 719 in³
Volume of composite figure = 667+719 = 1386 in³
Find the measure of angle FED and DEN. Thx!!!! :)
Answer:
m<FED=60, m<DEN=120
Step-by-step explanation:
m<FED=60
This is because <GEN and <FED are vertical angles.
Vertical angles are always congruent.
Vertical angles are formed by a pair of intersecting lines, and are the angles directly across from one another.
m<DEN=120
This is because <DEN and <GEN are supplementary.
Supplementary angles add up to 180 degrees.
We know this because a straight line is always 180 degrees.
So:
m<DEN+m<GEN=180
m<DEN+60=180
m<DEN=120

Write an inequality and show on a number line all numbers: from (–3) to 2 exclusives.
Answer:
The inequality is -3 < x < 2
The number line is included
Step-by-step explanation:
To express the numbers as an inequality, we have for exclusive numbers the form, [-3, 2] which gives;
-3 < x < 2
We note that an exclusive number (or larger than and lesser than inequality) is represented by an empty in the numbers excluded (for strict equality)
Therefore, we draw a number line with empty circles at number points -3, and 2 as follows;
-4 -3 -2 -1 0 2 1 2 3 4 5
A line contains the points (6,8), (-2, k) and (-10, 4). What is the value of k?
Answer:
k = 6
Step-by-step explanation:
Step 1: Find slope m
m = (4 - 8)/(-10 - 6)
m = -4/-16
m = 1/4
y = 1/4x + b
Step 2: Find b
4 = 1/4(-10) + b
4 = -5/2 + b
b = 13/2
Step 3: Rewrite equation
y = 1/4x + 13/2
Step 4: Find k
y = 1/4(-2) + 13/2
y = -1/2 + 13/2
y = 12/2
y = 6
Answer: 6
Step-by-step explanation:
As you move left to right on the x-coordinate, your y value is increasing. If you notice, the x values are increasing by eight at a time. So, if you take the value in between 4 and 8, you get your answer, which is 6.

EFG with vertices E(0,k), F(4,4) and G(7,8). EF
and FG have the same length.
(a) Find the value of k.
Answer:
k=1
Step-by-step explanation:
so FG and FE are equal meaning same magnitude
formula for magnitude is √{x2-x1}+{y2-y1}
(the square root is for all of it)
so use line FG since you have both points
you get √7 as magnitude
then apply it to FE
√7=√(4-0)+(4-k)
you can square both sides to remove the root and you get k=1
(when calculating magnitude the value is always absolute no regard to signs)

Answer:
25-y²/15 - y²/9 = 1Step-by-step explanation:
Given the equations x^2 + y^2=25 ...1 and x^2/15-y^2/9=1,.. 2 to solve the systam of equation we will make x^2 the subject of the formula from the first equation and substitute it into the second equation as shown;
Fom 1; x² = 25-y²... 3
Substituting equation 3 into 2 to get the resulting equation will give;
x²/15-y²/9=1
25-y²/15 - y²/9 = 1
The final expression gives the required equation.

Given a line segment AB drawn in a coordinate plane. The set of points that are the same distance from points A and B divides the line segment AB into two equal parts.
This line is referred to as the perpendicular bisector of AB.
Therefore, Carlos graphed the perpendicular bisector of AB.
The length of a rectangle is represented by L. If the width of the rectangle is one-half of its length, represent its width.
Answer:
L/2
Step-by-step explanation:
If the width is half of its length, that means it is 1/2*L, as L is the length. This can be simplified into L/2, which is our answer.
Answer:L/2
Step-by-step explanation: The length is represented as L. So half the lenght is 1/2L which can also be represented as L/2. So the width is represented as L/2

1/4 of a pipe is white , 1/2part of the remaining is blue. If the remaining part is black and the length of this blackpart is 5 1/4cm, find the length of the pipe.
Answer: 14 cm
Step-by-step explanation:
let's total length = h
white = 1/4h
remain = h - 1/4h
=3/4h
blue = 1/2 of remaining
=1/2 of 3/4h
=3/8h
remain part black = 3/4h - 3/8h
=3/8h
according to the question
3/8h = 5 1/4 cm
h = 14 cm
length of the pipe is 14 cm
Answer:
14The length of the pipe is 14.
Solution,
Let the total length be X cm
[tex]x - \frac{x}{4} -{ (x - \frac{x}{4} ) \times \frac{1}{2}} = 5 \frac{1}{4} \\ x - \frac{x}{4} - \frac{x}{2} + \frac{x}{8} = \frac{21}{4} \\ \frac{8x - 2x - 4x + x}{8} = \frac{21}{4} \\ \frac{3x}{8} = \frac{21}{4} \\ 3x \times 4 = 21 \times 8 \\ 12x = 168 \\ x = \frac{168}{12} \\ x = 14[/tex]

The test statistic of z equals = 2.94 2.94 is obtained when testing the claim that p not equals ≠ 0.877 0.877. A. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. B. Find the P-value. C. Using a significance level of alpha α equals = 0.01 0.01, should we reject Upper H 0 H0 or should we fail to reject Upper H 0 H0?
Answer:
Step-by-step explanation:
The claim being tested is that p not equals ≠ 0.877
A) This is the alternative hypothesis and it is a two tailed test. It means that it can be in either direction.
B)Given that z = 2.94, the p value would be determined from the normal distribution table. Since the curve is symmetrical and it is a two tailed test, the p for the left tail and the right tail would be considered. We will look at the area in both tails. Since it is showing in one tail only, we would double the area
From the normal distribution table, the area above the test z score in the right tail is 1 - 0.998 = 0.002
We would double this area to include the area in the left tail of z = - 2.94 Thus
p = 0.002 × 2 = 0.004
C) Since alpha, 0.01 > than the p value, 0.004, then we would reject the null hypothesis, H0
Find the coordinates of point B that lies along the directed line segment from A(-5, 2) to C(11, 0) and partitions the segment in the ratio of 5:3.
Answer:
B ( 5 , 3/4 )
Step-by-step explanation:
Solution:-
We are given two points in the cartesian coordinate system as:
A ( -5 , 2 ) C ( 11, 0 )
The point B lies on the line segment from A to C. The ratio of segment given is:
AB / BC = 5 / 3
To solve such type of problems. We will use vector equation of line AC.
To form a vector equation of line representing AC. We will first determine the direction vector ( d ) that is parallel to the line AC as follows:
d = OC - OA
d = < 11, 0 > - < -5,2 >
d = < 16 , -2 >
The fixed point on the line is taken. We will take point A. The vector equation of line from point A to point C is expressed as:
< x , y > = OA + t*d
< x , y > = < -5, 2 > + t* < 16 , - 2 >
The above equation satisfies all the points that lies on the line AC. To determine the coordinates of ( B ). We will plug in the appropriate value of parameter ( t ) and evaluate. We are given the ratio 5:3.
So point B is 5/8 th the magnitude of the distance AC from A. Hence, t = 5/8 as follows:
< x , y > = < -5 , 2 > + ( 5/8 ) * < 16 , -2 >
< x , y > = < -5 , 2 > + < 10 , -5/4 >
< x , y > = < 5 , 3/4 > ... Answer

The revenue for a company producing widgets is given by y=-25x^2-50x+200, where x is the price in dollars for each widget. The cost for the production is given by y=25x-10. Determine the price that will allow the production of the widgets to break even.
Answer:
When they create 3.44 products and make a revenue of $76.027, they will break even.
Step-by-step explanation:
To do this, simply graph the 2 equation in a graphing calculator and analyze the graph for where the 2 graphs intersect. Discard the negative intersection because we cannot have a negative production. You should see that your intersection point is (3.441, 76.027).
