Rhianna took a total of 10 pages of notes during 2 hours of class. In all, how many hours will Rhianna have to spend in class before she will have a total of 15 pages of notes in her notebook? Assume the relationship is directly proportional.
Answer:
Step-by-step explanation:
if 10 pgs = 120 mins
then 15 pgs = 15 × 120÷10
=1800÷10
= 180 mins
if 60 min = 1 hr
then 180 min = 180×1÷60
= 3 hrs
thus it will take her 3hours
Which inequalities have 4 as a solution? 1. X-85.2 <_ 14.6 4. 8x <_ 128 2. X/6> -23 5. X+4.7>21.6 3. X-43<37 Put the numbers together to form the code.
Given:
The inequalities are:
1. [tex]x-85.2\leq 14.6[/tex]
2. [tex]\dfrac{x}{6}>-23[/tex]
3. [tex]x-43<37[/tex]
4. [tex]8x\leq 128[/tex]
5. [tex]x+4.7>21.6[/tex]
To find:
The inequalities that have 4 as a solution.
Solution:
We need to put [tex]x=4[/tex] in each inequality, to check whether it is a solution or not.
1. The inequality is
[tex]x-85.2\leq 14.6[/tex]
Putting [tex]x=4[/tex], we get
[tex]4-85.2\leq 14.6[/tex]
[tex]-81.2\leq 14.6[/tex]
This statement is true. So, the inequality [tex]x-85.2\leq 14.6[/tex] has 4 as a solution.
2. The inequality is
[tex]\dfrac{x}{6}>-23[/tex]
Putting [tex]x=4[/tex], we get
[tex]\dfrac{4}{6}>-23[/tex]
[tex]0.67\leq -23[/tex]
This statement is true. So, the inequality [tex]\dfrac{x}{6}>-23[/tex] has 4 as a solution.
3. The inequality is
[tex]x-43<37[/tex]
Putting [tex]x=4[/tex], we get
[tex]4-43<37[/tex]
[tex]-39<37[/tex]
This statement is true. So, the inequality [tex]x-43<37[/tex] has 4 as a solution.
4. The inequality is
[tex]8x\leq 128[/tex]
Putting [tex]x=4[/tex], we get
[tex]8(4)\leq 128[/tex]
[tex]32\leq 128[/tex]
This statement is true. So, the inequality [tex]8x\leq 128[/tex] has 4 as a solution.
5. The inequality is
[tex]x+4.7>21.6[/tex]
Putting [tex]x=4[/tex], we get
[tex]4+4.7>21.6[/tex]
[tex]8.7>21.6[/tex]
This statement is false. So,4 is not a solution of the inequality [tex]x+4.7>21.6[/tex].

Answer:
26.25 square feet
Step-by-step explanation:
Calculation to determine the area of the seat
Using this formula
Area=1/2*(b1+b2)*h
Where,
b1=8 feet
b2=7 feet
h=3.5 feet
Let plug in the formula
Area=1/2*(8+7)*3.5
Area=1/2*15*3.5
Area=26.25
Therefore the area of the seat is 26.25 square feet

Answer:
x = 3
y = 8
Step-by-step explanation:
ok we will substitute
y = x + 5
into the second equation
4x + y = 20
4x + (x + 5) = 20
5x + 5 = 20
5x = 15
x = 3
y = x + 5 = 3 + 5 = 8
Answer:
4(3)+y=20
Step-by-step explanation:
4*3=12
Y= 3+5
3+5=8
12+8=20

8 mm: 24 cm in its simplest form is
Answer:
1mm:3cm
Step-by-step explanation:
8mm:24cm
---------------- = 2mm:6cm
4
2mm:6cm divided by 2 equals 1mm: 3cm
The required simplest form of 8mm; 24cm is 1mm; 3cm.
We have to determine, the simplest form of 8 mm: 24 cm.
To obtain the simplest form of the equation calculation must be done in a single unit following all the steps given below.
The ratio is just a way to compare two quantities while the proportion is an equation that shows that two ratios are equivalent.
Here, 8 mm: 24 cm.
Therefore,
[tex]8mm \ ; 24cm[/tex]
Divided by 8 both sides,
[tex]= \dfrac{8mm}{24cm}\\\\= \dfrac{1mm}{3cm}[/tex]
Hence, The required simplest form of 8mm; 24cm is 1mm; 3cm.

Solve the equation 506x - 92y + 90 = 498 - 4x + 6y
506 x - 92 y + 90 = 498 - 4 x + 6 y
Geometric figure:
line
y = (255 x)/49 - 204/49
510 x - 98 y - 408 = 0
506 x - 92 y + 90 = 6 (y + 83) - 4 x
Real solution:
y = (255 x)/49 - 204/49
Solution:
y = (255 x)/49 - 204/49

A rectangle and a triangle have the same area.
The dimensions of the rectangle are 3 cm and 10 cm. The base of the triangle is 6 cm.
What is the height of the triangle? How do you know?
Answer:
Height of the triangle = 10 cm
Step-by-step explanation:
Given:
Dimensions of rectangle = 3 cm , 10 cm
Base of triangle = 6 cm
Find:
Height of the triangle
Computation:
Given that area of rectangle is equal to area of triangle
So,
(l x b) = (1/2)(b)(h)
(3 x 10) = (1/2)(6)(h)
30 = 3(h)
h = 10
Height of the triangle = 10 cm

2x2 – y = –5
Answer:
x=-2,y=10
Step-by-step explanation:
y=8-x.............equation 1
4-y=-5..........equation 2
Now,
putting the value of y in equation 2,
4-(8-x)=-5
4-8+x=-5
