7th GRADE MATH RATIOS HELP TIME ALMOST OUT
Answer:
8, 40, 28.6, 40, 80, 36.6
Step-by-step explanation:
First find out what the ratio of tulips and roses is for each garden.
Ben: 40÷(4+1) = 8 so 8×4=32 and 8×1= 8
Ina: 40÷(2+5) =5.7 so 2×5.7=11.4 and 5×5.7= 28.6
Use these numbers accordingly.
Seems odd that there would be decimals in a problem like this, consult your teacher.
Answer:
8, 40, 28.6, 40, 80, 36.6

Diver descends 25 feet
She then descends another 25 feet
Total length descended= 25+25= 50 feet
Answer:
C
Step-by-step explanation:
Withdrawal means minus 30 dollars, so right now she is -30 dollars. But depositing is positive, so 30 + (-30) is 0.
8th grade math!! need to get a good grade!
Answer:
Bonnie :
(0,12),(1,16)
Slope = (16 - 12) / (1 - 0) = 4/1 = 4
So Bonnie is adding $ 4 every week to her savings
Bobby :
y = 12x + 4
The slope here is 12.....so he is adding $ 12 every week to his savings
Therefore, the rate at which Bobbie is adding to his savings each week is (12 - 4) = $ 8 more then the rate at which Bonnie is adding to her savings account each week
Referring to the figure, find the surface area
of the pyramid shown. Round to the nearest whole number.
Answer:
297 is the surface area
Step-by-step explanation:
Ok this problem is very simple.
First lets define some equations.
Area of a triangle: A = 1/2BH
A = Area B = Base H = Height
This equation works for right triangles only.
(because 2 right triangles make a square which is why it's multiplied by 1/2 because it's half a square).
Area of a square: A = BH
Surface area equals all the areas of each side added together.
First lets find the area of one of the triangles.
We know 11 is the base and 8 is the height but the triangle isn't a right triangle.
To make it a right triangle divide the base by 2 so 11/2.
You will get 5.5.
Now find the area!
A = 1/2BH
A = 1/2(5.5)(8)
A = 1/2(44)
A = 22
So now we found the area of the right side as a right triangle but you must multiply it by 2 to get the entire side (because we divided the base by 2).
22(2)=A
44=A
44 is the area of one side of the pyramid but there are 3 other sides (not including the base).
So just do:
44+44+44+44 = A
176 = A
Surface area for the triangles is 176!
Now we must find the area of the square.
A = BH
A = 11(11)
A = 121
Total surface area is all the areas added together so it's:
121+176=A
297

The best answers get brainliest
Answer:
51414
Step-by-step explanation:
1000+2000 = 3000
3000+4000 = 7000
5000+600+70 = 5670
3000 + 5670 = 8670
8670 + 7000 = 15,670
80+9+69+12+35,574= 35744
35744 + 15,670 = 51414
Answer:
1000+2000+3000+4000+5000+600+70+80+9+69+12+35,574= 51,414

Melissa wants to buy a new pair of shoes that have an original price of $45. Melissa has a coupon for 20 percent off to use on them, which amounts to a discount of $9. If sales tax is 9 percent on the final price of the shoes, how much tax will she need to pay?
$3.24
$4.05
$4.86
$4.95
Answer:
$3.24
Step-by-step explanation:
First, we subtract the $9 from the $45, so that equals $36
9% of the 36% is added to the final price as tax
36 x 0.09 = 3.24
Answer:
45-9=36
what we could do is first find out how much 1% is, 36÷1=0.36.
so 0.34×9=3.24
the final answer is 3.24
Find an equation of the line that passes through the points (2,6) and (-4.6). Write the equation in slope-intercept form.
Answer:
change in y /change in y to get the gradient . therefore (6--6)=12 and (2--4)=6 thus 12/6=2 that the gradient.
Step-by-step explanation:
form the equation ion form of y=mx+c
and thus the equation y= 2x+c
if you take one point coordinate such as (2,6)
such that y=6 and x=2 thus the equation will be
6=2*2+C
6=4+C
C=6-4=2
therefore answer is
Y=2X+2
Answer:
Y=2X+2

Which equation is equivalent to 4(p + 8) = 2(r – 6) when solved for r?
Answer:
[tex]r=2p+22[/tex]
Step-by-step explanation:
[tex]4(p+8)=2(r-6)\\4p+32=2r-12\\4p+32+12=2r\\4p+44=2r\\\frac{4p+44}{2} =\frac{2r}{2} \\2p+22=r[/tex]
Hope this helps you
Let me know if you have any other questions :-)
The equation equivalent to 4(p + 8) = 2(r – 6) when solved for r is
r = 2p + 22.
To solve for r in the equation 4(p + 8) = 2(r – 6), follow these steps:
1. Distribute the numbers: Distribute the numbers on both sides of the equation.
[tex]\[4 \cdot p + 4 \cdot 8 = 2 \cdot r - 2 \cdot 6\][/tex]
2. Simplify: Perform the calculations on each side of the equation.
[tex]\[4p + 32 = 2r - 12\][/tex]
3. Isolate r terms: Move the terms containing r to one side of the equation by adding 12 to both sides.
[tex]\[4p + 32 + 12 = 2r\][/tex]
[tex]\[4p + 44 = 2r\][/tex]
4. Divide by 2: Divide both sides by 2 to solve for r.
[tex]\[\frac{4p + 44}{2} = r\][/tex]
[tex]\[2p + 22 = r\][/tex]
Thus, the equation 4(p + 8) = 2(r – 6) when solved for r becomes r = 2p + 22.
