The number that has 3 hundreds, 4 more tens than hundreds, and 1 more one than hundreds is 374.
Explanation:The student is asking us to construct a number based on place value criteria. To assemble this number, we will assign the digits to their appropriate places based on the given conditions. Three hundreds means the hundreds place must be 3, so we have '3' in the hundreds place. Since there are 4 more tens than hundreds, we add 4 to 3, giving us 7, which becomes the digit in the tens place. Lastly, there is 1 more one than hundreds, meaning we need to add 1 to 3 to get 4 for the ones place. Therefore, our number is 374, as it meets all the conditions: 3 hundreds, 7 tens (which is 4 more than the hundreds), and 4 ones (which is 1 more than the hundreds).

Answer: $37.45(to the nearest hundredths)
Step-by-step explanation:
% increase in last year living cost =5%
% increase in last year income =5%
This year income = $39.420
To calculate last year income implies
5% decrease of this year income; thus:
5/100 * $39.420 = $1.971
Last year income = $39.420 - $1.971 = $37.449 = $37.45 (to the nearest hundredths)

ok so her bills or wateva went up 5% right and she gets a lil 5% raise or sumn from her job which made her money got up to $39.42. so if you think about it all you do is multiply 39.42 and (5%) which = 0.05 in decimal form and then after you multiply you should get 1.9710 and once you get that you gone take her money she getting now which is 39.42 - her 5% raise she got and once you subtract you gone get 37.4490 or 37.45 rounded
Find an equation of the line containing the given pair of points.
(4.6, -8) and (6.6, 2.2)
The equation of the line containing the given pair of points (4.6 , -8) and (6.6 , 2.2) is y = 5.1 x - 31.46
Step-by-step explanation:
The equation of a line is y = m x + b, where
m is the slope of the line, [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] , where [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are 2 points lie on the lineb is the y-intercept, to get it substitute x and y in the equation by the coordinates of one of the 2 given points∵ The line contains the points (4.6 , -8) and (6.6 , 2.2)
∴ [tex]x_{1}[/tex] = 4.6 and [tex]x_{2}[/tex] = 6.6
∴ [tex]y_{1}[/tex] = -8 and [tex]y_{2}[/tex] = 2.2
∵ [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
- Substitute the values above in the rule of m
∴ [tex]m=\frac{2.2-(-8)}{6.6-4.6}=\frac{2.2+8}{2}=\frac{10.2}{2}=5.1[/tex]
∴ The slope of the line is 5.1
∵ The equation of a line is y = m x + b
Substitute m by 5.1
∴ y = 5.1 x + b
To find b substitute x and y by the coordinates of point (4.6 , -8) OR point (6.6 , 2.2)
∵ x = 6.6 and y = 2.2
∴ 2.2 = 5.1(6.6) + b
∴ 2.2 = 33.66 + b
- Subtract 33.66 from both sides
∴ -31.46 = b
∴ y = 5.1 x + (-31.46)
∴ y = 5.1 x - 31.46
The equation of the line containing the given pair of points (4.6 , -8) and (6.6 , 2.2) is y = 5.1 x - 31.46

If 8 cases of merchandise cost 60$, what would a dozen cases cost?
Answer: $90
Step-by-step explanation: First, we can change "one dozen" to 12 since it represents the same value.
To find out how much 12 cases of merchandise will cost, we will need to find the unit price per case of merchandise.
Unit price means the cost per unit in this case, the cost per case of merchandise.
Since we know that it costs $60 for 8 cases of merchandise, to find the cost for 1 case of merchandise, we need to divide 8 into $60 or $60 ÷ 8.
60 ÷ 8 = 7.50
Now, we know that it costs $7.50 for 1 case of merchandise.
To find the cost for 12 cases of merchandise, we will multiply the cost for 1 case of merchandise by the number of cases of merchandise we have.
In this case, we will multiply 7.50 by 12 which gives us 90.
Therefore, a dozen cases of merchandise will cost $90.

A restaurant sold 350 less hotdogs than hamburgers. Altogether the restaurant sold 700 hotdogs and hamburgers. How many of each did they sell?
Answer:
The restaurant sold 175 hotdogs and 525 hamburgers.
Step-by-step explanation:
Let the restaurant sold x hotdogs and y hamburgers.
Given the restaurant sold 350 more hamburgers than hotdogs.
So, we can write x + 350 = y ....... (1)
Again given that the number of total hotdogs and hamburgers sold in the restaurant is 700.
So, x + y = 700 ........ (2)
Solving equations (1) and (2) we get
2x + 350 =700
⇒ 2x = 350
⇒ x = 175
Then from equation (1) we get,
y = 350 + 175 = 525
Therefore, the restaurant sold 175 hotdogs and 525 hamburgers. (Answer)
I’m thinking of three consecutive odd integers. When I add the larger two the result is nine less than three times the smallest of them. What are the three consecutive odd integers?
To find the three consecutive odd integers, we can solve an equation representing the given information.
Explanation:Let the smallest odd integer be x. The next consecutive odd integer will be x + 2, and the largest odd integer will be x + 4.
The problem states that when the larger two integers are added, the result is nine less than three times the smallest integer:
(x + 2) + (x + 4) = 3x - 9
Simplifying the equation, we have:
2x + 6 = 3x - 9
Adding 9 to both sides:
2x + 15 = 3x
Subtracting 2x from both sides:
15 = x
So the smallest odd integer is 15. The consecutive odd integers are 15, 17, and 19.

Step-by-step explanation:
A ball is thrown and it follows a parabolic path. At each horizontal distance (x) the following equation models the ball’s height (y).
Y(x) = [tex]-0.02x^{2} +0.8x+3[/tex]
Question asked is " What will be height (Y) of the ball when X=10 ft "
Simply putting value of X in given equation
we get,
Y(x) = [tex]-0.02x^{2} +0.8x+3[/tex]
Y(x) = [tex]-0.02(10)^{2} +0.8(10)+3[/tex]
Y(x) = [tex]-0.02(100)} +8+3[/tex]

Therefore, Height of the ball at a horizontal distance of 10 feet is 9 ft
Answer D. 9 ft is correct
The height of the ball at a distance of 10 feet according to the given equation is 9 feet (option D). This was achieved by substituting the value of 10 into the equation.
Explanation:To find the height of the ball at a distance of 10 feet, you need to substitute the value for the horizontal distance (x) in the given equation. The equation modeling the ball's height is: Y=-0.02x^2+0.8x+3. So, we replace x with 10 in this equation, as follows:
Y=-0.02(10)^2+0.8(10)+3 Y=-0.02(100)+8+3 Y=-2+8+3 Y=9
Therefore, the height of the ball at a distance of 10 feet is 9 feet, so option D is correct.

5(2x-7)
Step-by-step explanation:
Given that 2/3a = 16, which of the following illustrates how the multiplicative inverse
property can be used to find the value of a?
Since the multiplicative inverse of a fraction p/q is the fraction that swaps its numerator and denominator, i.e. q/p, we have that the inverse of 2/3 is 3/2.
So, if we multiply both sides of the equation by 3/2, we have
[tex]\dfrac{3}{2}\cdot\dfrac{2}{3}a=16\cdot\dfrac{3}{2}[/tex]
3/2 and 2/3 are multiplicative inverse of each other, and by definition this means that they give 1 when multiplied:
[tex]\dfrac{3}{2}\cdot\dfrac{2}{3}a=1\cdot a=a=16\cdot\dfrac{3}{2}[/tex]
On the right hand side, we have
[tex]16\cdot\dfrac{3}{2}=8\cdot 3=24[/tex]
And so the solution is [tex]a=24[/tex]

Answer:
[tex]\large\boxed{5\dfrac{3}{10}\ hectometers=530\ meters}[/tex]
Step-by-step explanation:
[tex]PREFIXES\\\\mega\ (M)=10^6\\\\kilo\ (k)=10^3\\\\hecto\ (h)=10^2\\\\deko\ (da)=10\\\\decy\ (d)=10^{-1}=0.01\\\\centi\ (c)=10^{-2}=0.01\\\\mili\ (m)=10^{-3}=0.001\\\\mikro\ (\mu)=10^{-6}=0.000001[/tex]
[tex]5\dfrac{3}{10}=5.3\\\\1\ hectometers=100\ meters\qquad(1\ hm=100m)\\\\5\dfrac{3}{10}\ hm=5.3\ hm=5.3\cdot100\ m=530\ m[/tex]
