vivien's handspan measure 18.5 centimeters.estimate the number of times Vivien uses her handspan to measure a length of 1 meter 75 centimeters
Answers
Estimate what is 175 ÷ 18.5 . It cant be 10 because 18.5 is 185 which is greater than 175 , so lets estimage Vivien will have to use her handspan 9 times.
Final answer:
Vivien would use her handspan, which measures 18.5 centimeters, approximately 9 times to measure a length of 1 meter 75 centimeters. This estimate assumes precision in her handspan measurement.
Explanation:
To estimate the number of times Vivien uses her handspan to measure a length of 1 meter 75 centimeters, we need to divide the total length by the length of her handspan. Since Vivien's handspan measures 18.5 centimeters, and the total length to measure is 1 meter 75 centimeters (which equals 175 centimeters), we perform the following calculation:
Convert 1 meter 75 centimeters to all centimeters: 1 meter = 100 centimeters, so 1 meter 75 centimeters = 100 + 75 = 175 centimeters.Divide the total length by the length of Vivien's handspan: 175 cm/18.5 cm =9.45945945945946Round the result to the nearest whole number to estimate the number of handspans: approximately 9 times (since we typically round down when the decimal is less than 0.5).This is an estimation technique that assumes Vivien's measurement with her handspan is accurate. The accuracy of this measurement can vary based on several factors, including the precision of Vivien's handspan and the method used for measuring.

Leon works at a grocery store for $8 an hour. He also mows lawns for $10 an hour. He needs to earn at least $120 per week, but he does not want to work more than 20 hours per week. Use a system of inequalities to find a possible combination of hours he can work at the grocery store and mowing lawns in order to meet his goal.
Answers
Answer:
The data we have is:
He works for $8 an hour.
He mows lawns for $10 an hour.
He wants to work no more than 20 hours per week, and wants to hearn at least $120 week.
So if S is the number of hours he works in the store, and M is the number of hours that he mowns lawns, we have the inequalities:
S + M ≤ 20
S*$8 + M*$10 ≥ $120
So let's choose a possible solution:
Let's select M = 12 and S = 0
in this way, he worsk
0h + 12 h = 12 h that is less than 20 hours, and he wins:
0*$8 + 12*$10 = $120, which is the minimum amount of money that he wants to win.
and we have a lot of other possible solutions:
S= 1, M = 12
S = 2, M= 12.. and so on.
The population of a city in 2005 was 18000. By 2010, the city’s population had grown to 45,000. Economists have determined that the growth is exponential. If they are correct, what is the projected population for 2015?
Answers
and approx projected population is 45,000+18000=63,000
your answer is 63,000
Solution:
we are given that
The population of a city in 2005 was 18000.
By 2010, the city’s population had grown to 45,000.
Economists have determined that the growth is exponential.
As we know the exponential growth is defined by the relation
[tex]P=p_0e^{rt}\\ \\ \text{where P is the population at time t and initial population is } p_0\\[/tex]
Here we have [tex]p_0=18000, P=45000, t=5[/tex]
substitute these values we get
[tex]45000=18000e^{5r}\\ \\ r=0.183[/tex]
So we get
[tex]P(t)=18000e^{0.183t}[/tex]
So For population is 2015 substitute t=10
[tex]P(10)=18000e^{0.183*10}[/tex]
[tex]P(10)=112209.9598 [/tex]
The projected population for 2015 is 112210

Suppose one third of each of 5 same sized posters is covered with opaque paper.What fraction of the posters are Not covered by opaque paper?Explain how to use multiplication to find what part of the posters are not covered by opaque paper?
Answers
Final answer:
Two-thirds of each poster are not covered with opaque paper. Multiplying (2/3) by 5 gives us 10/3, which can be converted to 3 and 1/3, indicating that three whole posters plus one-third of another are not covered.
Explanation:
If one third of each of 5 same sized posters is covered with opaque paper, then two thirds of each poster are not covered. To find what fraction of the posters are not covered by opaque paper, you apply multiplication. You start with one poster: one-third covered means two-thirds are not covered. Represent this as 2/3. Since the question concerns 5 identical posters, you multiply the fraction of one poster (2/3) by the number of posters (5).
Mathematically, this looks like:
(2/3) × 5 = 10/3
However, 10/3 represents more than one whole, and it can be converted into a mixed number to represent the total unobstructed fraction of the posters. This is 3 and 1/3, meaning that in total, you have three whole posters and one-third of another poster not covered by opaque paper.

simplify 5.5a-1+21b+3a
Please help me
Answers
Final answer:
To simplify the expression 5.5a - 1 + 21b + 3a, combine like terms to get 8.5a + 21b - 1, which is the simplified form of the original expression.
Explanation:
To simplify the expression 5.5a - 1 + 21b + 3a, we need to combine like terms, which are terms that have the same variable raised to the same power. Here, 5.5a and 3a are like terms, and they can be combined by addition. There are no like terms for 21b or the constant -1, so they remain as they are.
Step 1: Combine the coefficients of like terms 5.5a and 3a: 5.5a + 3a = 8.5a.
Step 2: Rewrite the simplified expression with the combined like term: 8.5a + 21b - 1.
This is the simplified form of the original expression.

Then you add 35,000 and 40,000 to get 75,000 cm cubed
Answer:
C. [tex]75000\text{ cm}^3[/tex]
Step-by-step explanation:
We have been given a container and we are asked to find the volume of our given container.
We can see that our container is made of two cuboids, so we will use volume of cuboid formula to solve our given problem.
[tex]\text{Volume of cuboid}=\text{Length*Breadth*Height}[/tex]
We can from provided image that the base cuboid (bigger) has lengths 25 cm, 40 cm and 40 cm.
The height of smaller cuboid will be 25 cm (50 cm -25 cm). The other two sides of smaller cuboid are 35 cm and 40 cm.
[tex]\text{The volume of container}=\text{Volume of the bigger cuboid + Volume of the smaller cuboid}[/tex]
Upon substituting our given values in volume formula we will get,
[tex]\text{The volume of container}=\text{25 cm*40 cm*40 cm}+\text{25 cm*35 cm* 40 cm}[/tex]
[tex]\text{The volume of container}=40000\text{ cm}^3+35000\text{ cm}^3[/tex]
[tex]\text{The volume of container}=75000\text{ cm}^3[/tex]
Therefore, the volume of our given container is [tex]75000\text{ cm}^3[/tex] and option C is the correct choice.
Rewrite the following equation in slope-intercept form. 19x − 20y = -13 Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
19x = -13
X= -13/19
X=0
-20y=-13
Y= 13/20
Final answer:
To rewrite the equation 19x - 20y = -13 in slope-intercept form, you subtract 19x on both sides and then divide by -20 to isolate y. The resulting equation is y = (19/20)x + 13/20.
Explanation:
To rewrite the equation 19x - 20y = -13 in slope-intercept form, follow these steps:
Move 19x to the other side by subtracting it from both sides: -20y = -19x - 13
Divide by -20 to isolate y: y = (19/20)x + 13/20
Therefore, the equation in slope-intercept form is y = (19/20)x + 13/20.
If RS=59 AND ST=10x-31,find x
Answers
Answer: x=9
Step-by-step explanation:
In the given picture, we have a circle in which we have given two congruent arcs [tex]\overarc{RS}\text{ and }\overarc{TS}[/tex]
And [tex]\overline{RS}=59\text{ and }\overline{ST}=10x-31[/tex]
Since, we know that congruent arcs have congruent chords.
Therefore, [tex]\overline{RS}=\overline{ST}[/tex]
[tex]59=10x-31\\\\\Rightarrow\ 10x=59+31\\\\\Rightarrow 10x=90\\\\\Rightarrow x=\frac{90}{10}\\\\\Rightarrow x=9[/tex]
To solve the problem we must know the Chord's Equidistant From The Center Of A Circle Theorem.
Equidistance chordsIf two chords of a circle are equidistant from the center then they are congruent to each other and their corresponding arcs are also congruent.
The value of x is 9.
Given to usRS = 59,ST = 10x-31,In circle,Chord RS and chord ST are equidistant from the center. therefore,
RS = ST
[tex]59 = 10x-31\\ 59+31 = 10x\\ 90 = 10x\\\\ x= \dfrac{90}{10}\\\\ x= 9[/tex]
