Need help! What’s the answer to number two??
Answer:
V = 5(12)(7) which is F.
Step-by-step explanation:
V = LWH
L = 12
W = 5
H = 7
12 * 5 * 7
Answer:
if you need to find the area, the answer is 420, I think All in all the answer is F <last one>
Step-by-step explanation:
I think the first thing you do is L x W (12 x 5), which is 60. Then you do 60 x H (60 x 7), and you will get 420.
I am not entirely sure if I got it right.

You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost? Write the equation and solve. plz put the right answer
Answer:
[tex]5\[/tex]
Step-by-step explanation:
Let x be cost of 1 eraser.
[tex]5 +4x=25[/tex]
[tex]4x=20[/tex]
[tex]x=5[/tex]
Answer:
The buyer bought four erasers and a magazine for $25.
The cost of each magazine is $5
The cost of an eraser is x dollars
The cost of 4 erasers is 4x
Step-by-step explanation:
Cost of the Erasers + Cost of the Magazine = Total Cost
4x + $5 = $25
Subtract 5 from both sides to isolate the term with the variable.
4x + 5 -5 = 25 -5
4x = 20
The last thing you do is you divide it by 4 on both sides to isolate the variable.
x = 20/4 = $5
The accepted density of copper is 8.96 g/cm3. A lab team measured the density of a copper sample in a lab and calculated a density of 8.40 g/cm3. Part A: Which expression calculates the percent error for the calculated density of copper? Part B: What is the percent error? Select two answers: one for Part A and one for Part B. Answer Choices: B: 4.84% B: 6.51% A: 8.40|8.4+8.96|⋅100 B: 6.67% A: |8.40|8.96⋅100 A: |8.40−8.96|8.96⋅100 B: 2.33% A: |8.40−8.96|8.40⋅100
Answer:
A: [|8.40−8.96|/8.96]⋅100,
B. 6.25%
Step-by-step explanation:
A.
% error =[ | calculate density - accepted density|/ accepted density]*100%
A: [|8.40−8.96|/8.96]⋅100
B. |8.40−8.96|/8.96⋅100 = 6.25%
Use the discriminant to determine the number of real solutions of the equation.
x^2 = -6x - 10
Answer:
No real solutions.
Step-by-step explanation:
x² + 6x + 10 = 0
a = 1
b = 6
c = 10
D = b² - 4ac = 6² - 4*1*10 = 36 - 40 = - 4
- 4 < 0,
so this equation has no real solutions.
An angle is bisected by a segment forming two new angles. ∠ 1 and ∠ 2. Find m ∠DBC if m ∠2 = 27.
Wouldn’t it be still 27? So, like 27 + 27 = DBC?
Answer:
Yes, it will still be 27? So, like 27 + 27 = DBC.
Answer:
54
Step-by-step explanation:
Bisecting means to divide in half
<1 = <2
If <2 = 27 , then <1 = 27
The sum of the angle = 27+27 = 54
If DBC is the original angle, then DBC = 54

Help to answer 2 & 3 Pablo and Jasmine had just started studying systems of linear equations in algebra. They looked at Pedro's drawing and said, "We could write that as a system of equations." Let t be the price of each taco and d be the price of each drink. - Write an equation that represents the cost of Pablo's order. (6T + 2D = 9) - Write an equation that represents the cost of Jasmine's order. (4T + 2D = 7) 2. What operations with the equations from part (1) match your way of using Pedro's sketch to find the prices t and d? 3. Why do the operations make sense?
Answer:
Step-by-step explanation:
The equation for Pablo's order is given as 6T+2D=9 or 6T+2D-9=0
While the equation for Jasmine's order is given as 4T+2D=7 or 4T+2D-7=0
Subtracting Jasmine's equation from Pablo's
6T+2D-9-(4T+2D-7)=0
This gives us
6T+2D-9-4T-2D+7=0
The reduces to
2T-2=0
Dividing all through by 2 gives
T-1=0
Therefore
T=1
Substituting the value for T into any of the equations of either Pablo and Jasmine
Using Pablo's
6T+2D=9
6(1)+2D=9
2D=9-6
2D=3
There D= 3/2

Calculate the perimeter of ABCD
Answer:
28.13 cm
Step-by-step explanation:
The first step we need to do is create the segment AC.
Then, we can find its length using the law of cosines in the triangle ABC:
b^2 = a^2 + c^2 - 2*a*c*cos(B)
b^2 = 8^2 + 6^2 - 2*8*6*cos(95)
b^2 = 64 + 36 - 96*(-0.0872)
b^2 = 108.37
b = 10.41 cm
Then, in the triangle ADC, we can use the Pythagoras' theorem to find the length of DC:
DC^2 + DA^2 = AC^2
DC^2 + 25 = 108.37
DC^2 = 83.37
DC = 9.13 cm
So the perimeter of ABCD is:
Perimeter = AB + BC + CD + DA
Perimeter = 6 + 8 + 9.13 + 5 = 28.13 cm
Answer:
The perimeter of the shape is 28.13 cm
Step-by-step explanation:
First of all, we will have to draw a line from point A to point C. This will divide the shape into two parts, both of which are triangles.
We will use the dimensions of the newly formed triangle ABC to get the side AC.
The cosine formula will be apt for this purpose:
[tex]AC^{2}=AB^{2}+BC^{2}-(2 \times AB\times BC\times cos \theta)[/tex]
[tex]AC^{2}=6^{2}+8^{2}-(2 \times 6\times 8\times cos( 95))=108.37[/tex]
[tex]AC=\sqrt{108.37}=10.41 cm[/tex]
Now we have AC as 10.41 cm,
we can see that AC forms the hypothenuse of the right-angled triangle ADC.
From Pythagoras' theorem, DC can be calculated as
[tex]DC =\sqrt{AC^{2}- AD^{2}}[/tex]
[tex]DC =\sqrt{10.41^{2}- 5^{2}}= 9.13 cm[/tex]
Therefore the perimeter of the shape is 8 + 5 + 9.13 + 6 =28.13 cm
The perimeter of the shape is 28.13 cm

On a coordinate plane, 5 parallelograms are shown. Parallelogram L M N P has points (3, 1), (4, 1), (4, 3), and (5, 3). Figure D is reflected across the x-axis. Figure B is reflected across the y-axis. Figure C is rotated in the first quadrant. Figure A is rotated in the third quadrant. Which figure represents the image of parallelogram LMNP after a reflection across the line y = x? figure A figure B figure C figure D
Answer:
Figure C
Step-by-step explanation:
Reflection across the line y = x transforms point (x, y) into (y, x)
(3, 1) -> (1, 3)
(4, 1) -> (1, 4)
(4, 3) -> (3, 4)
(5, 3) -> (3, 5)
After rotation, all points remain in the first quadrant. Figure C is rotated in the first quadrant, then it is the correct option.
Because Figure C is rotated in the first quadrant,its represents the image of parallelogram LMNP after a reflection across the line y = x
What is a Parallelogram?A Parallelogram is simply a four-sided quadrilateral with opposite sides parallel to each other.

Sidney is eating lunch at a salad bar where you
create your own salad. An 8-ounce salad costs
$2.49. Each additional ounce of salad costs
$0.25. How much does Sidney’s salad cost if it
weighs 1 pound, 8 ounces?
Answer:
$7.47
Step-by-step explanation:
Since a 8-ounce salad cost 2.49
You do 2.49+1 pound times 0.25
1 pound equals to 16 ounces
2.49 + 2.49 + 2.49
Correct. If I am wrong
Answer:
Step-by-step explanation:
the base is 2.49 for eight ozs so you already take off the ozs from 1 pound
since there are 16 ounces in one pound you multiply 16 by .25 and get 4 so you add 2.49 and 4 to get 6.49$ is the answer assuming there is no tax on the food
You want the volume of the box to be 9 cubic inches.
Find the rational solution(s) of the equation. Then use polynomial long division to find the other solution(s).
What are the possible side lengths of the box?
Odyssey ware Answer: 9 = 3 x 3 x 3
Step-by-step explanation:
If the volume of the box is 9. The possible side lenths are:
V = L x W x H
9 = 3 x 3 x 3.
What I did was estimated how 9 could be split up into 3 so that it’ll make sense for L x W x H.
