Answer:
-2
Step-by-step explanation:
a - 6 - 6a = 4
a-6a=10
-5a=10
a=10/-5
a=-2
Answer:
a = -2
Step-by-step explanation:
Add like terms:
a - 6 - 6a = 4
-5a - 6 = 4
Solve for a:
-5a = 10
a = -2
So, a = -2
find the surface area of the composite figure - image attached,, need answer now!!
Answer:
Surface Area = 392 cm²
Step-by-step explanation:
Green (front):
SA = 1/2bh
= 1/2 (12) (8)
= 48 cm²
Green (left side):
SA = bh
= 5 (10)
= 50 cm²
Green (right side):
SA = bh
= 5 (10)
= 50 cm²
Green (back):
SA = 1/2bh
= 1/2 (12) (8)
= 48 cm²
Blue (front):
SA = bh
= 12 (4)
= 48 cm²
Blue (left side):
SA = cm²
= 5 (4)
= 20 cm²
Blue (right side):
SA = bh
= 5 (4)
= 20 cm²
Blue (back):
SA = bh
= 12 (4)
= 48 cm²
Blue (bottom):
SA = bh
= 12 (5)
= 60 cm²
Total:
48 + 50 + 50 + 48 + 48 + 20 + 20 + 48 + 60 = 392 cm²
pls help what is the mode to this
Answer:
To find the mode for a set of numbers, find the number that is seen most often in the given dataset.
Step-by-step explanation:
For you to understand what I am talking about, I will give you an example:
48, 56, 7, 12, 40, 13, 39, 70, 7, 81, 83, 88, 100, 10, 0, 87
For this set, 7 is the mode because it's seen 2 times in the set while all the other numbers are seen only 1 time.
I hope it helps you!

A sales representative earns pay as described above. During a holiday promotion, he earned $650. What were his total sales for that week?
Described above:
Choose the correct equation. Then solve the equation.
A sales representative earns weekly base salary of $250 and a commission of 8% on her weekly sales. (A commission is money earned that equals a percent of the sales.) At the end of one week, she earned $410. How much did she sell that week? Let s represent the total sales.
A. 250 + 0.08s = 410
B. 250 + 410 = 0.08s
Answer:
A
Step-by-step explanation:
Use cross multiplication
Using the GCF and distributive property, which expressions is equivalent (equal) to 12y + 16
A 2(6y + 80)
B 4(3y + 4)
C 28y
D 16 + 12y
Answer:
4(3y+4)
Step-by-step explanation:
12y + 16
4*3*y +4*4
Factor out 4
4(3y+4)
Answer:
2(6y+80) = 12y+160
4(3y+4) = 12y+16
28y = 28y
16+12y = 12y+16 (did not use distributive property)
So, B is correct.

Can someone help me with this two because I am very confused
Answer:
Let the height of the larger box = h
and length and width of the larger box = l and w , repectively
Now , Let find the volume of the larger box
Volume = length * width * height
So Volume of the larger box = l*w*h = lwh
Now the question says
the height of the smaller box is 80% of the height of the larger box
It means
Height of the smaller box = 80% of h = 0.80*h = 0.80h
and the other two dimensions are same so it means length and width of the smaller box = l and w
so, Volume of the smaller box = l*w*0.80h = 0.80lwh
So the Difference in the volume of the two boxes = Volume of larger box - Volume of smaller box
therefore , Difference in the Volume of two boxes = lwh - 0.80 lwh = 0.20lwh
Step-by-step explanation:

Graph y = 2x + 2 * Make a table of ordered pairs

Find the area of the figure at the right in square feet. (image attached)
Answer:
40.5 ft²
Step-by-step explanation:
*First we’ll split the shape into multiple smaller ones. The two ends make separate triangles while the middle makes a rectangle. From there you can solve for their areas.
*Each triangle is the same size, so when solving them, the area of one can just be duplicated. To find the height of each triangle, we take the total base of 8 ft and subtract the top 5.5 ft to get 2.5 ft. After that you’ll divide by 2 (for each triangle) so the height of each one is 1.25 ft.
Triangle:
A = 1/2bh
A = 1/2 (6) (1.25)
A = 3.75 ft²
Both triangles:
A = 3.75 (2)
A = 7.5 ft²
Rectangle:
A = lh
A = 5.5 (6)
A = 33 ft²
Total:
A = 7.5 + 33
A = 40.5 ft²
Answer:
Step-by-step explanation:
The shape can be broken down into 2 identical triangles and one rectangle.
Area of 2 triangles= 2(1/2×base×height)
= 2(1/2×6×2.5) = 15ft²
Area of Rectangle = length × breadth
= 6 × 5.5 = 33ft²
Area of figure = Area of 2 triangles + Area of Rectangle
= (15 + 33) ft² = 48ft²

A hostel has provision for 45 students for 30 days.If 15 more students joined the hostel after 6 days,how long will provision last?
Answer:
It's the second answer
Step-by-step explanation:
It's the second question because the pattern is that the amount of food coloring is always 3 times more then the amount of frosting so it's point M because the amount of frosting is 50 so the amount of food coloring has to be 150 according to the ratio.

What is the value of the expression shown below? 7 + (10 - 4 )^2 divided 4 x (1/2)
Answer:
43 / 2 = 21 1/2 = 21.5
Step-by-step explanation:
7+(10-4)^2/ 4 (12) you can either multiply by 4(1/2)/4(12) or do the following
Subtract 4 from 10 to get 6.
7+6^2 / 4×( 1/2)
Calculate 6 to the power of 2 and get 36.
7+36 / 4×( 1/2 )
Add 7 and 36 to get 43.
43 / 4× 1/2
Multiply 4 and 1/2 to get 2.
43 / 2 = 21 1/2 = 21.5

17 - 12m = -11(m-2)
Answer:
-5 = m
Step-by-step explanation:
17 - 12m = -11(m-2)
Distribute
17 -12m = -11m +22
Add 12m to each side
17 -12m+12m = -11m+22+12m
17 = m+22
Subtract 22 from each side
17 -22 = m+22-22
-5 = m
[tex]\underline{\sf \: 17 - 12m = -11(m-2)}[/tex]
Use the distributive property to multiply -11 by m-2.
17 - 12m = - 11m + 22
Add 11m to both sides.
17 - 12m + 11m = 22
Combine -12m and 11m to get -m.
17 - m = 22
Subtract 17 from both sides.
- m = 22 - 17
Subtract 17 from 22 to get 5.
- m = 5
Multiply both sides by -1.
[tex]\large\boxed{\underline{\bf \: m = -5}}[/tex]
Hope it helps.

pls help with part b only thank you
Answer:
The scale factor is k = 1/30
a)
The length of the wing on the model:
9 m * 1/30 = 900 cm * 1/30 = 30 cmb)
The area of the tail section of the plane:
80 cm² : (1/30)² = 80 cm² * 900 = 72000 cm² = 72000 * (1/100)² m² = 7.2 m²Answer:
The real plane's tail section is 2400 cm^2
Step-by-step explanation:
Well since the model is 1/30 of the real planes size
By multiplying the area of the tail section by 30 we should get the area of the real tail section in the plane
80*30= 2400 cm^2
The real plane's tail section is 2400 cm^2

Answer:
y=15x+25, the cost is 205 dollars
Step-by-step explanation:
The simplest way to write a rule for this is to write it in slope intercept form, y=mx+b. Let y represent the cost of the membership. Every month the cost is 15 dollars. If we let x represent the months we can rewrite this as 15x. The one time cost is 25 dollars so we can just add that to the end of the equation. y=15x+25. There are 12 months in a year so we just have to substitute. y=15(20)+25=205 so the answer is 205 dollars.
I'm confused on how to do this someone please help me
(A) (4, 6)
Step-by-step explanation:
Since the 2nd stage light is above P, then its x-coordinate is also the same as that of P, which is 4. We know that there are 2 units per grid and since the 2nd stage is 8 units above P, the conversion to the number of grids is
[tex]8\:\text{units}×\dfrac{1\:\text{grid}}{2\:\text{units}} = 4\:\text{grids}[/tex]
So count 4 grids above the location of P, which is (4, -2) and you will get the coordinate (4, 6).

A textbook is 14/15 inch thick. How many
textbooks can be stacked on a shelf that is
56 inches high?
Answer:
60 textbooks
Step-by-step explanation:
1) 56*15:14=60
Answer:
60 textbooks
Step-by-step explanation:
To get the answer, you have to divide 56 by 14/15. What I'd do is id think of 56
as 56/1. I'd change 14/15 into a multiplicative inverse/reciprocal, ending up with 15/14. From there, id multiply 56/1 and 15/14, ending up with 840/14.Using long division, id do 840 divided by 14, ending up with 60.
Rewrite using a negative exponent.
1/3^2
Answer:
1/9 or 3^-2
Step-by-step explanation:
Ignore the value of 1/3 for now and just focus on the 3^2.
Find 3^2:
3*3 = 9
Now 9 is the denominator, therefore our answer would be 1/9 once you reassemble the fraction.
Because 1/9 is our new fraction, we can use a negative exponent to create the same result. This is because the negative exponent rule tells us that a number with a negative exponent should be put to the denominator. Therefore we can then use 3^-2.
Answer:
3^-2
Step-by-step explanation:
Express each of these percentages as a fraction
12.4%
solution for class 7
Answer:
31/250
Step-by-step explanation:
12.4% as a fraction
lets get rid of the decimal by multiplying it by 10 = 124
Since we multiplied 12.4 by 10, we multiply 100 by 10 as well
124/1000 = 62/500 = 31/250
