1/10 + 70/100 = help me pleas
Answer:
0.8 or 8/10
Step-by-step explanation:
1/10 can be converted to decimal form as 0.1.
70/100 can be converted to decimal form as 0.7
0.1 + 0.7 = 0.8
Another way is making use of a common denominator:
Common denominator --> 100
1/10 --> mutiply numerator and denominator by 10 --> 10/100
10/100 +70/100 = 80/100 = 8/10 = 0.8

A straw is placed inside a rectangular box that is 5 inches by 8 inches by 3 inches, as shown. If the straw fits exactly into the box diagonally from the bottom left corner to the top right back corner, how long is the straw? Leave your answer in simplest radical form.
The length of the straw will be 9.89949 inches long in radical form.
What is Length of diagonal in cuboid?If a cuboid has length = l units, breadth = b units, and height = h units, then we can evaluate the length of the diagonal of a cuboid using the formula
[tex]X^2=l^2+b^2+h^2[/tex]
As per the question the length of the straw is equal to length of the diagonal of Rectangular box.
l= 5 inch , b= 8 inch , h= 3 inch
Let us consider the length of the straw be 'x'.
As, Diagonal of Cuboid is,
[tex]X^2+l^2+b^2+h^2[/tex]
[tex]X^2=5^2+8^2+3^2[/tex]
[tex]X^2=25+64+9[/tex]
[tex]X^2=98[/tex]
[tex]X=\sqrt{98}[/tex]
X= 9.89949 (in radical form)
Hence, the length of the straw will be 9.89949 inches.

find the missing angle,
thanks.
Given :
48°
90°{boxed like shape}
x + 48 + 90° = 180°{sum of angles of triangle}
x + 138° = 180°x = 42°~Tulpe⚘
Answer:
x = 42°
Step-by-step explanation:
Given that,
→ A = 48°
→ B = 90°
→ C = x
Formula we use,
→ A + B + C = 180°
Let's solve for the value of missing angle,
→ A + B + C = 180°
→ 48° + 90° + x = 180°
→ 138° + x = 180°
→ x = 180° - 138°
→ [ x = 42° ]
Hence, value of missing angle is 42°.

1. In 2012, the population of a city was 5.68 million. The exponential growth rate was 2.99% per year.
a) Find the exponential growth function.
b) Estimate the population of the city in 2018.
c) When will the population of the city be 10 million?
d) Find the doubling time.
Answer:
So first we need to determine what the exponential growth function would look like. Exponential growth functions look like [tex]P(t) = P_0*e^{r*t}[/tex] and in our case [tex]P_0[/tex] would be the initial population which is 5.68 million. R is the next variable that we need to fill out which is the rate of change which in our case is 2.99% or 0.0299.
This is how our function should look now [tex]P(t)=5.68*e^{0.0299*t}[/tex]
Moving onto part b, we need to estimate the population of the city in 2018 which 6 years from 2012 and we plug that into t and solve.
[tex]P(t)=5.68*e^{0.0299*6}[/tex]
[tex]P(t)=5.68*e^{0.1794}[/tex]
[tex]P(t) = 5.68*1.1965[/tex]
[tex]P(t) = 6.796\ million[/tex]
Moving onto part c, we need to find when the population of the city will be 11 million which will be done by setting P(t) to 10 million and solving for t.
[tex]10 = 5.68*e^{0.0299*t}[/tex]
[tex]\frac{10}{5.68} = \frac{5.68*e^{0.0299*t}}{5.68}[/tex]
[tex]1.76056=e^{0.0299*t}[/tex]
[tex]ln(1.76056)=ln(e^{0.0299*t})[/tex]
[tex]\frac{0.5656}{0.0299}=\frac{0.0299*t}{0.0299}[/tex]
[tex]18.9175\ years = t[/tex]
Moving onto part d, we need to find the doubling time. This will be similar to the previous part but we will be finding the time it takes to double our population. So instead of putting 10 million for P(t) we put 5.68* 2 in there which is 11.36.
[tex]11.36= 5.68*e^{0.0299*t}[/tex]
[tex]\frac{11.36}{5.68} = \frac{5.68*e^{0.0299*t}}{5.68}[/tex]
[tex]2=e^{0.0299*t}[/tex]
[tex]ln(2)=ln(e^{0.0299*t})[/tex]
[tex]\frac{0.693}{0.0299}=\frac{0.0299*t}{0.0299}[/tex]
[tex]23.182\ years = t[/tex]

a circular donut has a diameter of 7 cm the circular hole in the center of the donut has a radius of 1.5cm. find the circumference of the donut
7 is the radius of the donut
7 is the circumference of the donut
7 is the diameter of the donut
Step-by-step explanation:
1.5 times 1.5 when doing so u need to round it to the tenths place
Answer:
31.4
Step-by-step explanation:
To find circumference, the formula is A=pi*r^2. The radius is 1/2 the diameter. The radius of the donut is 3.5. 3.5^2 is 12.25. Pi is approximately 3.14, so 12.25*3.14 is 38.465. The donut hole takes away from the circumference, so we have to subtract the circumference of the donut hole from the donut. 1.5^2 is 2.25, and 2.25*3.14 is 7.065. 38.465-7.065 is 31.4. The circumference of the circle is 31.4.

From a candy machine a random handful of colored chocolate candies are dispensed with 2 quarters. In one turn the machine dispenses 3 blue candies, 5 red candies, and 4 yellow candies. If you hide them in your hand and drop them one at a time into the other hand to eat them, what is the probability that the first candy will be blue and the second candy will be yellow?
Answer:
the answer should be 1/11
Step-by-step explanation:
p(blue first) = 3/12
p(yellow second) = 4/11
so p = 3/12 x 4/11
1/11 is your probability
Select all the expressions that are equivalent to -2(4-3x)+(5x-2)
Answer:
2. 11x - 10
3. -8 + 11x - 2
5. -8 + 6x + 5x -2
Step-by-step explanation:
To find the equivalent expressions, find the solution to the expression -2(4 - 3x) + (5x - 2). All expressions that are within the solving process or have the same solution are equal to the given expression.
-2(4 - 3x) + (5x - 2)
-2(4 - 3x) + 5x - 2
-8 + 6x + 5x - 2
-8 + 11x - 2
11x - 10
In this case, the equivalent expressions were within the solving process. From this, we can see that the equivalent expressions are 11x - 10, -8 + 11x - 2, and -8 + 6x + 5x - 2. Aka choices 2, 3, and 5.

Which of the following estimates at a 95% confidence level most likely comes
from a small sample?
A. 48% (+21%)
B. 53% (+3%)
C. 59% (+5%)
D. 67% (+7%)
Answer:
Option A
Step-by-step explanation:
95% confidence interval is obtained using the following formula
COnfidence interval lower bound = mean - critical value * sigma/sq rt n
and upper bound = mean + critical value*sigma/sq rt n
Thus margin of error = critical value*sigma/rt n
varies indirectly as n provided others are remaining the same.
Hence lower sample indicates higher margin of error
Out of 4 options given we find that I option has maximum margin of error as 21%
Hence option A is most likely coming from a small sample

Tim, the baker, is purchasing two types of chocolate: milk and dark. every month he needs at least 50 pounds of milk chocolate and 40 pounds of dark chocolate. his supplier offers two brands he can purchase.brand x costs $12 a box and has 8 pounds of milk chocolate and 4 pounds of dark chocolate. brand y costs $15 a box and has 5 pounds of milk chocolate and 10 pounds of dark chocolate. part a how many boxes of each brand should tim purchase to minimize cost? enter the values in the first and second response boxes. part b enter the total cost in the third response box.
Answer:
yes thank you ..I'm sure that's is answerMultiplication is the process of multiplying. The total cost of the boxes of two types is $90.
What is multiplication?
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The cost of the first box is $12, which has 8 pounds of milk chocolate and 4 pounds of dark chocolate.
The cost of the second box is $15, which has 5 pounds of milk chocolate and 10 pounds of dark chocolate.
Therefore, if we buy the 5 boxes of the first type and 2 boxes of the second type, then the amount of two chocolate that Tim needs will be fulfilled.
The cost of 5 boxes of the first type is $60 ($12 ×5), while the cost of 2 boxes of the second type is $30 ($15×2), therefore, the total cost of the boxes of two types is $90.

Answer: 480 sq ft
Step-by-step explanation:
for two rectangles on right do 8*16 =128*2 = 256
the rectangle on the right is also 128
total of all rectangles is 384 ft
now for the triangles
formula: 1/2 b*h
1/2 * 16*6 = 48
multiply that by 2 for both triangles
you have 96
add that to total and you get
480 sq ft
Answer:
Step-by-step explanation:
The hypotenuse of the triangles is the length of the rectangles so the length of the rectangles is 16 ft. The width of the rectangles is 8 ft. There are 3 rectangles so the surface area of them is:
(16*8)*3 = 384[tex]ft^{2}[/tex]
The area of a triangle is base times height divided by two. Here, the height of the two triangles is 6 ft and the base is 16 ft. So, the area of the two triangles is:
[tex]\frac{6*16*2}{2}[/tex] = 16*6 = 96 [tex]ft^2[/tex]
Add the two areas together to get the surface area.
384[tex]ft^2[/tex] + 96[tex]ft^2\\[/tex] = 480[tex]ft^2[/tex]
Hence, the surface area of the triangular prism is 480[tex]ft^2[/tex]
