Answer:
350.82
Step-by-step explanation:
To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.
The rectangle's area ([tex]lw[/tex]):
[tex]7.21*14=100.94[/tex]
The triangle's area ([tex]\frac{1}{2}bh[/tex]):
[tex]\frac{1}{2} (6)(8)[/tex]
[tex]\frac{1}{2} (48)=24[/tex]
Now add up all the sides. (3 Rectangles, 2 Triangles.)
[tex]100.94 + 100.94 + 100.94 + 24 + 24[/tex]
[tex]=350.82[/tex]
The total surface area is 350.82 cm squared.
Two number cubes each have sides labeled 1 to 6. Ann rolls both number cubes. On the first roll, the sum of the numbers was equal to 8. On the second roll, the sum of the numbers was equal to 6. Is one of these sums more likely to occur?
Answer:
yes.
Step-by-step explanation:
because i know
Answer:
No.
Step-by-step explanation:
The table shows the possible sums of rolling the two dies. There are 5 combinations for both the sum of 6 and 8. Therefore, neither 6 nor 8 are more likely to occur.

Find the fifth term when a1=4 and r=-3
Answer:
a₅ = 324
Step-by-step explanation:
The nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex] then
a₅ = 4 × [tex](-3)^{4}[/tex] = 4 × 81 = 324

A 40% sugar solution is added to an 85% sugar solution to create 1800 mL of a 60% solution. How much of each solution is used? (Use either elimination or substitutions) SHOW ALL STEPS PRETTY PLEASE !!
Answer:
Number of ml of 40% sugar = x = 1000mL
Number of ml of 85% sugar used = y = 800mL
Step-by-step explanation:
Let the
Number of ml of 40% sugar = x
Number of ml of 85% sugar used = y
From the above question, our system of equations is given as:
x + y = 1800mL ....... Equation 1
x = 1800 - y
40% × x + 85% × y = 60% × 1800mL
0.4x + 0.85y = 1080.... Equation 2
We substitute 1800 - y for x in Equation 2
0.4(1800 - y) + 0.85y = 1080
720 - 0.4y + 0.85y = 1080
- 0.4y + 0.85y = 1080 - 720
0.45y = 360
y = 360/0.45
y = 800mL
Solving for x
x = 1800 - y
x = 1800 - 800
x = 1000mL
Therefore,
Number of ml of 40% sugar = x = 1000mL
Number of ml of 85% sugar used = y = 800mL

$1215 is deposited in account that pays 6.5% annual interest, compounded continuously what is the balance after 8 years?
Answer:
FV= A= $2,043.66
Step-by-step explanation:
Giving the following information:
Initial deposit= $1,215
Interest rate= 6.5% compounded continuously
Number of years= 8
To calculate the future value, we need to use the following formula:
A= P*(e^rt)
A= Future value
P= principal
r= rate of interest
t= time in years
A= 1,215*(e^0.065*8)
A= $2,043.66

Write and solve an equation to find the values of d and w .
Answer:
d = 65°
w = 55°
Step-by-step explanation:
m∠DAC +∠m∠CAB = 60
m∠DAC + 35 = 60
m∠DAC = 25
m∠DAC + d = 90
25 + d = 90
d = 65°
m∠GAF + w + d = 180
60 + w + 65 = 180
w + 125 = 180
w = 55°

samuel can do 9 word problem s in 25 minutes at this rate about how many word problem can he do in 42 minutes
Answer:
15 word problems
Step-by-step explanation:
Given that
Samuel can do 9 word problems in 25 minutes
So we need to find out how he can do the word problems in 42 minutes
The calculation is given below;
= 9 × 42 minutes ÷ 25 minutes
= 15.12
= 15 word problems
Hence, the same would be considered and relevant
Can someone tell me the answer?
As the number of pounds of apples purchased increases so does the total cost of the apples. If 2.5 pounds of apples cost $7.45, how much does 6 pounds of apples cost?
First divide
6/2.5=2.4
Then multiply
7.45*2.4=17.88
6 pounds of apples cost $17.88
Cody has $7. He wants to
buy at least 4 snacks. Hot
dogs (x) are $2 each.
Peanuts (y) are $1 each.
Which ordered pair is a
solution?
x + y 24
2x + y s7
1,1 or 1,3
=====================================================
Explanation:
Note that the two shaded regions overlap to form the darker shaded region. The point (1,1) is only in the green region, but not in the blue region. It needs to be in both regions for it to be a solution to the system. In contrast, the point (1,3) is on the boundary of the blue region and in the green region as well. It's a solution point because of this.
Points on the boundary are included because of the "or equal to" as part of the inequality sign. Hence the solid boundary lines rather than dashed boundary lines.
The solution (1,3) means that x = 1 and y = 3 pair up together. It says that Cody can buy x = 1 hotdog and y = 3 packs of peanuts so that he has at least 4 snacks, and he stays within the $7 budget.
Going back to (x,y) = (1,1) for a moment, this isn't a solution because x+y = 1+1 = 2 is not 4 or larger. In other words, he only buys 2 snacks here instead of 4 or more.

What is the range of y= x + 2?
Answer:
A) all real numbers greater than or equal to 2
Domain: [tex]x\geq 0[/tex]
Step-by-step explanation:
The variable in the radical x cannot be less than 0 as that wouldn’t be defined. So, the maximum that x can be is 0, and [tex]y=x+2[/tex]. So, 0+2=2, and y is greater than or equal to 2.
Domain is x is greater than or equal to 0 because you cannot square a negative. So, it must not be less than 0. It could be 0 because square root of 0 is just 0.
-4x + 1 = -11
how do i solve this
Answer:
3
Step-by-step explanation:
- 4x + 1 = - 11
- 4x = - 11 - 1
- 4x = - 12
x = - 12 / - 4
x = 3
Answer:
-4X+1=-11
-4x=-11-1
-4x=12
x=12/4
x=3
