Answer: 114 marbles
Step-by-step explanation:
From the question, we are told that a bag contains red and black marbles which are 120 marbles in total. We are further told that there are 19 red marbles for every black marble.
Let the number of black marbles be represented by a.
The red marbles will be: = 19 × a = 19a
Based on the information given in the question,
Black marbles + Red marbles = 120
a + 19a = 120
20a = 120
a = 120/20
a = 6
Black marbles = 6
Red marbles = 19a = 19 × 6 = 114 marbles

A new hospital in Springfield starts out with 11 junior residents and 5 senior readings on its staff. Management plans to to hire additional personnel at a rate of 1 junior resident per month and 3 senior residents per month. Eventually there will be an equal number of each on the hospital staff. How long will that take? How many of each type will be there be?
Answer:
3 months
14 of each type of staff
Step-by-step explanation:
Starting employees
Junior residents = 11
Senior readings = 5
Additional personnel at a rate of 1 junior resident per month and 3 senior residents per month
Junior residents = 11 + m
Senior readings = 5 + 3m
Where,
m = number of months
How long will that take?
Equate both expression
11 + m = 5 + 3m
11 - 5 = 3m - m
6 = 2m
Divide both sides by 2
m = 6/2
= 3
m = 3 months
Junior residents = 11 + m
= 11 + 3
= 14
Senior readings = 5 + 3m
= 5 + 3(3)
= 5 + 9
= 14
The volume of a box is 1800 cubic Inches. If the length of the box is 10 inches and its width is 3 inches more than its height, find the width and
height of the box.
Answer:
The width of the box is 15 inches and its height is 12 inches
Step-by-step explanation:
Equations
The volume of a box of width W, height H, and length L is given by:
V=W*L*H
We know
L=10 inches
W=H+3
V=1800 cubic meters
Substituting:
1800=(H+3)*10*H
Operating and swapping sides:
[tex]10H^2+30H=1800[/tex]
Dividing by 10:
[tex]H^2+3H=180[/tex]
Rearranging:
[tex]H^2+3H-180=0[/tex]
Factoring:
(H-12)(H+15)=0
The only positive and valid result is:
H=12 inches
Thus,
W=H+3=12+3=15 inches
The width of the box is 15 inches and its height is 12 inches

Answer:
5 and 0
Step-by-step explanation:
The answer to x > -45, are all number that are larger than -45.
5: Is 50 larger than -45
-100: Is 55 smaller than -45
-50: Is 5 smaller than -45
0: Is 45 larger than 45
5 and 0 are correct because they are both larger than -45.
Answer:
Well from the question I can only confirm that X (-45, infinity) is the possible answer. The answer would be A and D because 5 is greater than -45, while 0 is also greater than -45.

a tiny house has a length of 25 feet. the width of the kitchen is 3 feet, and the width of the remain space is 12 feet. which expression represents the area of the tiny house?
Answer:
I'm not good at Math, so I'm not gonna be like give me brainiest, but I try to help. I think the answer would be D. 25(3+12) this mean add 12+3=15 15*25= 375, but it does not ask you to solve, but if you have 3 feet for the kitchen a 12 feet is remaining size and the house is 25 15 is not yet 25 so you would multiply.
Step-by-step explanation:
I hope this helps.
Answer:
It is D
Step-by-step explanation:
25(3+12)

A company makes steel rods shaped like cylinders. Each rod has a diameter of 6 centimeters and a height of 40 centimeters. The company uses, on average, 48,607cm^3 of steel each hour to make these rods. How many rods does the company make, on average, each hour?
Answer:
The number of rods used by the company is 43 rods/hour
Step-by-step explanation:
Given;
diameter of the cylinder, d = 6 cm
radius of cylinder, r = d/2 = 3 cm
height of the cylinder, h = 40 cm
Volume of the steel rod is given by;
V = πr²h
V = π(3)²(40)
V = 1131.12 cm³
The number of rods used by the company on average each hour is given by;
[tex]n = \frac{48,607 \ cm^3}{hour} *\frac{1}{1131.12 \ cm^3}\\\\ n = 43 \ rods/hour[/tex]
Therefore, the number of rods used by the company is 43 rods/hour

Answer:
7. x = 28
8. x = 70
Step-by-step explanation:
7. 180 - 90 - 62 = 28
x = 28 (By i think the alternate interior angles theorem, haven't done geometry in a while so sorry if thats not the right theorem).
8.
180 - 110 = x
180 - 110 = 70
x = 70

For h( -5), just plug in the value -5 for whenever x occurs.
-4(-5) - 10 = 20 - 10 = 10
h(x) means a function h, at a point x.
Using this definition, we know that h(-5), is a function, (-4x - 10), at a poi
