Answer:
-24 degrees
Step-by-step explanation:
To find the total change in temperature, multiply 12 by -2, since it dropped 2 degrees each hour for 12 hours.
12*(-2)
= -24
This means -24°F was the total number of degrees the temperature dropped.
Answer:
The question mentions the keyword, "temperature drops" meaning we need to alternatively subtract.
[tex]t = -2 * 12[/tex]
If we know that positive 2 times 12 is 24, we know -2 times 12 will be negative 24°, because any negative number times a positive number is always a negative number.

A carpenter lays 15 ft2 of tile in 35 of an hour.
How many square feet of tile does the carpenter lay per hour?
Enter the correct answer in the box.
Answer:
16 is equivalent to 2/3 therefore you just multiply by 3/2 because 2/3 times 3/2 gives you one which would give you the number of square feet per hour and x would be the amount of square feet per hour made. To show in steps...
16=2/3x
16(3/2)= 2/3 (3/2)
24=1 hour

One half of one tenth is what fraction?
Answer: 1/20 or one twentieth
Work Shown:
1/2 = one half
1/10 = one tenth
(1/2)*(1/10) = (1*1)/(2*10) = 1/20
Basically we multiply the 2 and 10 to get 20 in the denominator.

What are the volume and surface area of the rectangular prism?
Answer:
I hope I did this right but
Box 1 - Surface Area = 324
Box 2 - Volume = 360
Step-by-step explanation:
Surface Area for rectangular prism - SA = 2(lw) + 2(lh) + 2(wh)
Volume for rectangular prism V = lwh

Thank you :)
Answer:
option C
Explanation:
For Naomi's rectangular prism:
⇒ Length × Width × Height
⇒ 5 × 14 × 2
⇒ 140 cm³
For Ben's triangular prism:
⇒ 1/2 × Base × Height × Length
⇒ 1/2 × 5 × 4 × 14
⇒ 140 cm³
The prism's have the same volume.
Answer: Choice C
===========================================================
Explanation:
The volume of the rectangular block is:
V = L*W*H = 5*14*2 = 70*2 = 140 cubic cm.
Now move onto the triangular prism.
The triangular face has a base of 5 cm and height of 4, so the area of this face is
A = base*height/2 = 5*4/2 = 20/2 = 10 square cm
Multiplying this with the depth of the prism tells us the volume is
V = (area of the base)*(depth) = (10 sq cm)*(14 cm) = 140 cubic cm
Therefore, the prisms have the same volume.

An account earns 3% yearly simple interest. How much interest will you earn in 5 years if you put $820 in the account
A. $130.60
B. $ 123.00
C. $943.00
D. $950.60
Answer:
[tex]the \: interest \: is \: 123.00(option \: b)[/tex]
Step-by-step explanation:
[tex]rate = 3\% \\ time = 5years \\ principal = 820[/tex]
[tex]interest = \frac{principal \: \times rate \: \times \: time}{100} [/tex]
[tex]interest = \frac{820 \times 5 \times 3}{100} [/tex]

A spinner is divided into 6 equal sections. Two sections are green,two sections are blue, and two sections are yellow. What is the ratio of yellow sections to total sections?
A. 2:6
B. 1:6
C. 3:6
D. 4:6
Answer:
A. 2:6
Step-by-step explanation:
we want to find the ratio of yellow sections to total sections
we are given that there are 2 yellow sections and 6 total sections
so the ration of yellow to total sections would be 2:6
Answer:
A) 2:6
Step-by-step explanation:
There is 2 yellow sections and total of 6 sections.
So it is 2:6
A bacteria that starts with 3 cells increases by 15% every hour.
Write an exponential growth equation that models the situation
How many bacteria cells will there be in 13 hours?
Answer:
Step-by-step explanation:
In order to determine the equation, consider that any exponential growth equation can be written as follow:
[tex]f(t)=A(1+r)^t[/tex]
where,
f(t): amount of bacteria after t hours
A: initial amount of bacteria = 3
r: growth rate in decimal form = 0.15 (15%)
t: time in hours
By replacing the previous values into the expression for f(t) you get;
[tex]f(t)=3(1+0.15)^t\\f(t)=3(1.15)^t[/tex]
Hence, the answer is f(t) = 3(1.15)^t
Now, replace t = 13 to determine the amount of bacteria after 13 hours:
[tex]f(13)=3(1.15)^13\\f(13)=18.46[/tex]
Hence, after 13 hours there are approximately 18 bacteria

How do i write improper fractions as mixed numbers?
Explain with examples
Answer:
You have to multiply the whole number by the denominator and then add the answer you get with the numerator.
Step-by-step explanation:
For example, the fraction 10 [tex]\frac{3}{5}[/tex] is a mixed number, right? So then you multiply 10x3=30. Then you add 30+5=35. So then the answer would be [tex]\frac{35}{5}[/tex].

Find the surface area of a rectangular prism that has the dimensions shown.
length: 4.5 in.
width: 6 in.
height: 12 in.
S
A
=
in
2
Answer:
S(A) = 306 in²
Step-by-step explanation:
The surface area of a rectangular prism can be found using the following equation:
SA(rectangular prism) = 2(wl + hl + hw)
Note:
w = width = 6
h = height = 12
l = length = 4.5
Plug in the corresponding numbers to the corresponding variables:
SA(rectangular prism) = 2((6 * 4.5) + (12 * 4.5) + (12 * 6))
SA(rectangular prism) = 2((27) + (54) + (72))
SA(rectangular prism) = 2(27 + 54 + 72)
SA(rectangular prism) = 2(153)
SA(rectangular prism = 306
S(A) = 306 in²

Answer:
C. The typical value is greater in set B. The spread is greater in set A.
Step-by-step explanation:
A typical value is the center of the dot plot, which is often found by finding the mean or median of the set. Both sets have 5 dots plotted. The spread of a set is how far the plotted values are from this center (mean or median).
Set A is shown to have more data spread out; values range from 0 to 7.
Center: (0 + 2 + 3 + 5 + 7)/5 = 3.4.Spread: 7 - 3.4 = 3.6 from the maximum to the center. 3.4 - 0 = 3.4 from the center to minimum.Set B is shown to have data that is more condensed and at higher values; ranges from 6 to 9, with two of the five points plotted at 6.
Center: (6 + 6 + 7 + 8 + 9)/5 = 7.2. Spread: 9 - 7.2 = 1.8 from the maximum to the center. 7.2 - 6 = 1.2 from the center to minimum.Set B has a higher typical value. Set A has a greater spread.
