The picture shows two boxes a teacher stacks in the storage closet.
What is the total volume of the two boxes?
A.56 cubic feet
B.21 cubic feet
C.48 cubic feet
D.68 cubic feet
Answer: 44ft^3
Step-by-step explanation:alright so ur gonna wanna split the boxes here, I recommend splitting it where there's a line between the small and big box. Now we got 2 boxes we already have all necessary measurements to find the volume of the large box so we do that one first
large box; 8×2×2= 32
now the small box if we look at the side of the big box we see its length is 2 so we just have to subtract 6-2 to find length of small box now we can solve.
small box; 3×2×2 = 12
now add 12+32= 44
Answer: 50
Step-by-step explanation:
Your first need to find the volume of each box separated. The bottom box has a length of 8ft., a width of 2ft., and a height of 2ft. Multiply all the dimensions to get a volume of 32ft. Now onto the top box. The length is 3 the width is also 2 and the height is 6 - 2 which is 3. Multiply all to get a volume of 18ft. Now add the two volumes. 18 + 32 = 50.

Determine the value of x.
Question 5 options:
A)
10
B)
10
C)
5
D)

Answer:
X is the hypotenuse and using 60°
Cos theta =adjacent/ hypotenuse
where 5 is your adjacent cos 60° is equals to 5/X
X= 5/Cos 60° = 5/0.5 = 10... B
The value of x will be;
⇒ x = 5
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle is shown in figure.
The perpendicular side = 5
The hypotenuse side = x
Now,
Since, We know that;
⇒ sin θ = Perpendicular / Hypotenuse
Put θ = 90°, we get;
⇒ sin 90° = 5 / x
⇒ 1 = 5 / x
⇒ x = 5
Thus, The value of x = 5

Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Match each indicated measure in the first column for
⊙
O
⊙O.
Answer:
Step-by-step explanation:
By the property,
"Measure of the intercepted arc is double of the inscribed angle"
m(arc BC) = 2×48°
= 96°
By using the same property,
m(arc AC) = 2 × m(∠B)
m(∠B) = [tex]\frac{110}{2}[/tex]
= 55°
m(∠A) + m(∠B) + m(∠C) = 180° [Triangle sum theorem]
48° + 55° + m(∠C) = 180°
m(∠C) = 180° - 103°
= 77°
m(arc AB) = 2 × (m∠C)
= 2×77
= 154°

JK, KL and LJ are all tangent to O (not drawn to scale). JA = 13, AL = 9, and
CK = 11. Find the perimeter of JKL.
a.)66
b.)44
c.)33
d.)48
Answer:
a.) 66
Step-by-step explanation:
Perimeter of JKL = JA + AL + CK + CL + KB + JB
JA = 13,
AL = 9,
CK = 11
CL = AL = 9 (tangents drawn from an external point are congruent)
KB = CK = 11 (tangents drawn from an external point are congruent)
JB = JA = 13 (tangents drawn from an external point are congruent)
Plug in the values
Perimeter of JKL = 13 + 9 + 11 + 9 + 11 + 13
= 66

On Saturday a roadside vegetable stand sold 5 pumpkins and 20 watermelons and made $135.
on Sunday the roadside vegetable stand sold 10 pumpkins and 16 watermelons and made $150.
what is the cost of the pumpkins and what is the cost of the watermelons ?
Answer:
Pumkins $7 and Watermelons $5
Step-by-step explanation:
let pumkins be P and watermelons be W s0
5P+20W=135 and 10P+16W=150
express first equation in terms of P
5P+20W=135
5P=135-20W (divide equation by 5)
P=27-4W
now express the second equation using the new P value
10P+16W=150
10(27-4W)+16W=150
270-40W+16W=150
120=24W
W=5
now plug in w value and solve for p
5P+20(5)=135
P=7

Find two consecutive whole numbers that √45 falls between.
The length of a rectangle is 4 less than 5 times the width. If the perimeter is 88 cm, find
the length and the width
Answer:
w = 8 so l = 36
Step-by-step explanation:
l = 5w - 4, so P = 88, then 2l + 2w = 88, so 2(5w - 4) + 2w = 88
10w - 8 + 2w = 88, so 12w = 96, so w = 8
Write the equation of a line that passes through the point (1,4) and has a slope of 9.
Answer:
y=9x-5
Step-by-step explanation:
You want to find the equation for a line that passes through the point (1,4) and has a slope of 9.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 9. So you can right away fill in the equation for a line somewhat to read:
y=9x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(1,4). When x of the line is 1, y of the line must be 4.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: b is what we want, the 9 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the point (1,4).
So, why not plug in for x the number 1 and y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!.
(1,4). y=mx+b or 4=9 × 1+b, or solving for b: b=4-(9)(1). b=-5.The equation of the line that passes through the point (1,4) with a slope of 9
is
y=9x-5
RideShare offers short-term rentals of vehicles that are kept in small lots in urban neighborhoods with plenty of potential customers. With one lot, it has eight cars. The interarrival time of potential demand for this lot from its base of customers is 40 minutes. The average rental period is five hours. If a customer checks availability of vehicles in this lot online and finds that they are all rented for the desired time, the customer skips renting and finds alternative arrangements. However, because customers pay a monthly fee to subscribe to this service, RideShare does not want customers to be disappointed too often.a. What is the offered load?b. What is the implied utilization?c. What is the capacity of the process (rentals per hour)?d. What is the probability that all eight cars are rented at the same time?e.

A telephone service representative believes that the proportion of customers completely satisfied with their local telephone service is different between the Midwest and the Northeast. The representative's belief is based on the results of a survey. The survey included a random sample of 1400 midwestern residents and 1320 northeastern residents. 50% of the midwestern residents and 38% of the northeastern residents reported that they were completely satisfied with their local telephone service. Find the 98% confidence interval for the difference in two proportions. Step 1 of 3 : Find the critical value that should be used in constructing the confidence interval.
Answer:
(0.1361 ; 0.2239)
Step-by-step explanation:
n1 = 1400 ; p1 = 0.50 ; n2 = 1320 ; p2 = 0.38
Confidence interval = mean ± margin of error
Mean = p1 - p2
Point estimate :
p1 - p2 = 0.50 - 0.38 = 0.18
Margin of Error (MOE) = Zcritical * S. E
Standard Error(S. E) :
Sqrt[(p1(1-p1)/n1) + (p2(1-p2)/n2)]
(p1(1-p1)/n1) = 0.50(0.50) / 1400 = 0.0001785
(p2(1-p2)/n2) = 0.38(0.62) / 1320 = 0.0001784
S. E = sqrt(0.0001785 + 0.0001784)
S. E = sqrt(0.0003569)
S. E = 0.0188917
Zcritical at 98% = 2.326
MOE = Zcritical * S. E
MOE = 2.326 * 0.0188917
MOE = 0.0439420942
MOE = 0.0439
Confidence interval = mean ± margin of error
Confidence interval = 0.18 ± 0.0439
Lower boundary = (0.18 - 0.0439) = 0.1361
Upper boundary = (0.18 + 0.0439) = 0.2239
(0.1361 ; 0.2239)
