Answer:
7^5 (7 to the fifth power)
Step-by-step explanation:
those sevens can be represented by 7^5 because there are five sevens to multiply together
you can check the answer by doing 7 x 7 x 7 x 7 x 7=16807
and making sure that 7^5 is also equal to 16807, which it is.

Answer:
DF = 9.5
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
DE × DF = DC × DB
5(5 + x) = 5(5 + 4.5) ← divide both sides by 5
5 + x = 5 + 4.5
5 + x = 9.5 ( subtract 5 from both sides )
x = 4.5
Then
DF = DE + EF = 5 + 4.5 = 9.5
An SRS of 100 flights by Nite-flite Airlines showed that 64 were on time. An SRS of 100 flights by Waxwing Airlines showed that 80 were on time. Let pN be the proportion of on-time flights for all Niteflite Airline flights, and let pW be the proportion of all on-time flights for all Waxwing Airlines flights. Is there evidence of a difference in the on-time rate for the two airlines
Answer:
Step-by-step explanation:
pN = 64/100 = 0,64 = 64%
pW = 80/100 = 0,8 = 80%
The planes of Waxwing airlines are more punctual

Answer: A. 384 sq. mm
Step-by-step explanation: The area for the square is 12x12 or 144. The area for a triangle is base x height x 1/2. Therefore, that would be 12 x 10 x 1/2 or 60. There are 4 sides to this pyramid, so 60 x 4 = 240. We then add 144 and 240 to get 384 sq. mm.
∠A and angle ∠B are vertical angles. If m∠ A=(2x-4) and ∠B = (x+1), then find the value of x
Answer:
x = 5
Step-by-step explanation:
vertical angles are equal so we can write this equation:
2x-4 = x+1
x - 4 = 1
x = 5
Jara quiere fabricar un cohete con cartulina. Para ello ha construido un cilindro de 0,25 metros de radio y medio metro de altura y un cono con el mismo radio y la mitad de la altura. ¿Que volumen ocupa su cohete? Ayudaaa
Respuesta:
0,114 m³
Explicación:
El volumen del cohete será igual a la suma de los volumenes del cilindro y del cono
Volumen del cilindro
El cilindro tiene un radio (r) de 0,25 m y una altura (h) de 0,5 m. Podemos encontrar su volumen usando la siguiente formula.
Vcil = π × r² × h
Vcil = π × (0,25 m)² × 0,5 m = 0,098 m³
Volumen del cono
El cono tiene un radio (r) de 0,25 m y una altura (h) de 0,25 m (la mitad de 0,5 m). Podemos encontrar su volumen usando la siguiente formula.
Vcono = 1/3 × π × r² × h
Vcono = 1/3 × π × (0,25 m)² × 0,25 m = 0,016 m³
Volumen del cohete
Vcohete = Vcil + Vcono = 0,098 m³ + 0,016 m³ = 0,114 m³
3. At a manufacturing plant, it is known that 8% of the computer chips produced are defective. A random sample of 20 chips is taken.
What is the probability that 3 of those chips are defective?
.
Answer:
Probability of three chip being defective is 0.012
Step-by-step explanation:
Probability of a computer chip being defective is 0.08 or 8%
Total random sample = 20
Probability of three chip being defective = 3/20 * 0.08
= 0.012
Answer:
B) 0.14
Step-by-step explanation:
N=20
K=3
P=0.08
CoE= 1140
1140 x (0.08)^3 x (.92)^17
1140 x (0.000512) x (0.2423) = 0.141425 or B

Answer:
1 gallon : 25.6 miles
Step-by-step explanation:
So, the way we can find the rate, or ratio between 2 units is to divide one unit by the other unit.
So basically, we see the first set of units is:
2 gallons - 51.2 miles
So basically, for every 2 gallons, there are 51.2 miles.
To find the ratio, or rate, we must find the miles per gallon.
We can do that by dividing both sides by 2:(g=gallons, m=miles)
2g/2=51.2/2m
=
g=25.6
So for every gallon, there is 25.6 miles.
We can write this as:
1 : 25.6
Hope this helps!
Answer:
25.6
Step-by-step explanation:
51.2/2=25.6
Tell whether the angles are complementary, supplementary, or neither
Answer:
neither
Step-by-step explanation:
43 + 57 = 100
Complementary angles: sum of measures = 90 deg
Supplementary angles: sum of measures = 180 deg
This question: sum of measures = 100 deg
Answer: neither
Answer:
Neither
Step-by-step explanation:
Supplementary angles are angles that have a common side and together have a value of 180 degrees.
Complementary angles are angles that together have a value of 90 degrees.
These angles do not add up to 180 degrees, and do not have a common side, so they are not supplementary. These angles do not add up to 90 degrees, so they are not complementary.

The volume of air in cylindrical jar is 334.60 [tex]cm^{3}[/tex].
What is the volume of cylinder?The formula to calculate volume of a cylinder is given by the product of base area and its height.
Given
Height = 33.3 cm
Diameter = 8 cm
Radius = [tex]\frac{Diameter}{2}[/tex] = 4 cm
The volume of cylindrical jar = height × Base area
= 33.3 × [tex]\pi.(4^{2} )[/tex]

A teacher asked four students to estimate the length of a grain of rice. Jack answered 4.5 x 10^-3 kilometer, Lilly answered 4.5 x 10^-3meter, Diego answered 4.5 x 10^-3vcentimeter, and Willa answered 4.5 x 10^-3 millimeter. Who gave the best answer
Answer:
Lilly
Step-by-step explanation:
According to the literature, the length of a medium grain rice is between 5.3 and 5.9 mm. Let's take the average (5.6 mm) and convert it to meters to compare it with the estimations. We will use the conversion factor 1 m = 1000 mm.
5.6 mm × 1 m/1000 mm = 5.6 × 10⁻³ m
Jack answered 4.5 × 10⁻³ kilometers. We will convert it to meters using the conversion factor 1 km = 1000 m.
4.5 × 10⁻³ km × 1000 m/1 km = 4.5 m
Lilly answered 4.5 × 10⁻³ meters.
Diego answered 4.5 × 10⁻³ centimeters. We will convert it to meters using the conversion factor 1 m = 100 cm.
4.5 × 10⁻³ cm × 1 m/100 cm = 4.5 × 10⁻⁵ m
Willa answered 4.5 × 10⁻³ millimeters. We will convert it to meters using the conversion factor 1 m = 1000 mm.
4.5 × 10⁻³ mm × 1 m/1000 mm = 4.5 × 10⁻⁶ m
As we can see, Lilly gave the best answer (same order of magnitude).

On selling an article for Rs 2300, a shopkeeper made a profit of 15 %. find the cost price of the article.
Answer:
Step-by-step explanation:
Sp of an article= Rs 2300
profit%=15%
let Cost Price of an article be X
SP=CP+PROFIT %*CP
2300=X+15/100*X
2300=100X+15X/100
2300*100=115X
230000/115=X
2000=X
Therefore cost price of an article is Rs 2000.

Jay pays $2.45 for 4 magazines. He later pays $3.75 for 6 magazines. Is the price proportional to the number of magazines? Explain
Answer:
No, It is not.
Step-by-step explanation:
Step 1: Divide the 2.45 by 4 (We are doing this to find the difference between them so we can find out what to do next.)
[tex]2.45 \div 4\\\\= 0.6125[/tex]
Step 2: Multiply 0.6125 to 6 (Now, that we've found what 1 magazine cost according to the first data, we are multiplying it by 6 because if you multiply that to 4 the answer will be 2.45. So, if we multiply 6, it will show us if they are both proportional, the same.)
[tex]0.6125 \times 6\\\\= 3.675[/tex]
Therefore, these two prices are not proportional.
