Joanna went school supply shopping. She spent $21.45 on notebooks and pencils. Notebooks cost $1.97 each and pencils cost $1.16 each. She bought a total of 15 notebooks and pencils. How many of each did she buy?
A.
5 notebooks; 10 pencils
B.
3 notebooks; 12 pencils
C.
8 notebooks; 7 pencils
D.
10 notebooks; 5 pencils
Answer:
A) 5 notebooks, 10 pencils
Step-by-step explanation:
n = notebook
p = pencil
1.97n + 1.16p = 21.45
A)✅
1.97(5) + 1.16(10) = 21.45
9.85 + 11.6 = 21.45
21.45 = 21.45
B) ❌
1.97(3) + 1.16(12) = 21.45
5.91 + 13.92 = 21.45
19.83 = 21.45

HELP, thanks.... If a triangle has side lengths of 3 inches and 4 inches, what must be true of the third
side?
a. The third side must be greater than 7 inches
b. The third side must be equal to or greater than 7 inches
c. The third side must be less than 7 inches
d. The third side must be less than or equal to 7 inches
Answer:
In a triangle the sum of any two sides must be greater than the third side. We have 3+4=7 which is less than 8. So this triangle is never true.
b. The third side must be equal to or greater than 7 inches

A sequence is defined by the recursive rule a1 = -16, an = 1.5an-1. What is the fourth term in the sequence?
Answer:
a(4) = 1.5(-36) = -54
Step-by-step explanation:
a(1) = -16 is given.
a(n) = 1.5*a(n-1).
a(2) = 1.5(-16) = -24
a(3) = 1.5(-24) = - 36
a(4) = 1.5(-36) = -54

Which of these lengths CANNOT represent the sides of a triangle? {28, 30, 58} {32, 34, 60} {13, 20, 27} {2, 4, 5}
Answer:
[tex]A.\ {28, 30, 58}[/tex]
Step-by-step explanation:
Required
Which of the lengths do not form a triangle
To do this, we make use of triangle inequality theorem which states that.
[tex]a + b > c[/tex]
[tex]b + c > a[/tex]
[tex]a + c > b[/tex]
Where [tex]a,\ b\ and\ c[/tex] are the sides of the triangle.
So, we have:
[tex]A.\ {28, 30, 58}[/tex]
[tex]28 + 30 > 58[/tex] --- False
[tex]58 + 30 > 28[/tex] --- True
[tex]28 + 58 > 30[/tex] --- True
[tex]B.\ {32, 34, 60}[/tex]
[tex]32 + 34 > 60[/tex] -- True
[tex]32 + 60 > 34[/tex] -- True
[tex]34 + 60 > 32[/tex] -- True
[tex]C.\ {13, 20, 27}[/tex]
[tex]13 + 20 > 27[/tex] -- True
[tex]13 + 27 > 20[/tex] -- True
[tex]20 + 27 > 13[/tex] --- True
[tex]D.\ {2, 4, 5}[/tex]
[tex]2 + 4 > 5[/tex] --- True
[tex]2 + 5 > 4[/tex] -- True
[tex]5 + 4 > 2[/tex] --- True
From the computations above, only (A) cannot form a triangle
There are 320 students in a school. 16 come to school by car. 96 walk to school. Estimate the probability that a particular student: a arrives by car b walks to school c does not walk to school d does not walk or come by car.
Answer:
a. The probability that a particular student arrives by car is [tex]\frac{1}{20}[/tex] = 0.05, which equals 5%.
b. The probability that a particular student walks to school is [tex]\frac{3}{10}[/tex] = 0.3, which equals 30%.
c. The probability that a particular student does not walk to school is [tex]\frac{7}{10}[/tex] = 0.7, which equals 70%.
d. The probability that a particular student does not walk or come by car is [tex]\frac{13}{20}[/tex] = 0.65, which equals 65%.
Step-by-step explanation:
Probability is the greater or lesser possibility of a certain event occurring. In other words, probability establishes a relationship between the number of favorable events and the total number of possible events. Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
[tex]P(A)=\frac{number of favorable cases}{number of possible cases}[/tex]
In this case, the number of possible cases is always the same, which is equal to the total number of students. So the number of possible cases is 320 students. The number of favorable cases varies as follows:
a. Number of favorable cases= number of students that arrive by car= 16
So: [tex]P(A)=\frac{16}{320}[/tex]
P(A)=[tex]\frac{1}{20}[/tex] = 0.05, which equals 5%
The probability that a particular student arrives by car is [tex]\frac{1}{20}[/tex] = 0.05, which equals 5%.
b. Number of favorable cases= number of students that walk to school= 96
So: [tex]P(A)=\frac{96}{320}[/tex]
P(A)=[tex]\frac{3}{10}[/tex] = 0.3, which equals 30%
The probability that a particular student walks to school is [tex]\frac{3}{10}[/tex] = 0.3, which equals 30%.
c. Number of favorable cases= number of students that do not walk to school = 320 students - number of students that walk to school= 320 students - 96 students= 224 students
So: [tex]P(A)=\frac{224}{320}[/tex]
P(A)=[tex]\frac{7}{10}[/tex] = 0.7, which equals 70%
The probability that a particular student does not walk to school is [tex]\frac{7}{10}[/tex] = 0.7, which equals 70%.
d. Number of favorable cases= number of students that do not walk or come by car= 320 students - number of students that walk to school - number of students that arrive by car= 320 students - 96 students - 16 students= 208 students
So: [tex]P(A)=\frac{208}{320}[/tex]
P(A)=[tex]\frac{13}{20}[/tex] = 0.65, which equals 65%
The probability that a particular student does not walk or come by car is [tex]\frac{13}{20}[/tex] = 0.65, which equals 65%.
A car traveled 180 kilometers in 3 hours. Which statement best describes the distance traveled by the car per hour?
Answer:
speed= 60km/h
Step-by-step explanation:
Given data
Distance= 180kilometers
Time= 3 hours
We know that the expression for the speed is
Speed= distance/time
Speed= 180/3
Speed= 60 km/h
Hence the answer is speed= 60km/h

Write an expression to represent the area of the rectangle below in simplest form.
Given:
The length of the rectangle is:
[tex]l=x^2-x+3[/tex]
The width of the rectangle is:
[tex]w=4x+1[/tex]
To find:
The area of the given rectangle in the simplest form.
Solution:
We know that, the area of a rectangle is:
[tex]A=l\times w[/tex]
Where, l is the length and w is the width of the rectangle.
Using the above formula, the area of the given rectangle is:
[tex]A=(x^2-x+3)\times (4x+1)[/tex]
[tex]A=x^2(4x)+x^2(1)-x(4x)-x(1)+3(4x)+3(1)[/tex]
[tex]A=4x^3+x^2-4x^2-x+12x+3[/tex]
[tex]A=4x^3-3x^2+11x+3[/tex]
Therefore, the area of the given rectangle is [tex](4x^3-3x^2+11x+3)[/tex] sq. units.

Answer: question 5 is C
Question 4 is 37.68
Question 3 is 153.86 ft sq
The question about finding the area with a diameter of 16mm is 803.84
The next one is A. 25÷8
Step-by-step explanation:
C = 2 pi r
C = 2 pi (7.8) and you get 49.01
Becuse the question is asking to round c is the best choice
When using the formula of C = 2 pi r, since radius is half of the diameter, 12÷2=6
The formula for this one is A = pi r sq
You have the radius for this one is 7
Put 7 into that and you get. ~153.94
Rian is packing toys in boxes. Each box is 3 inches by 4 inches by 6 inches. Each toy takes up 65% of the volume of the box, and the rest of the volume of the box is filled with foam packing beads. What is the volume, in cubic inches, of the foam packing beads used to fill each box
9514 1404 393
Answer:
25.2 in³
Step-by-step explanation:
The volume of the box is ...
V = LWH
V = (3 in)(4 in)(6 in) = 72 in³
__
65% of the box is filled with a toy, so the remaining 100% -65% = 35% is filled with packing beads. The volume of packing beads required is ...
0.35 × 72 in³ = 25.2 in³
25.2 in³ of foam packing beads are used to fill each box.
