Answer:
16.9% to the nearest tenth of a percent
Step-by-step explanation:
First, find the FINAL sale price (after the additional holiday 5% reduction).
If we wish to reduce $10,500 by 5%, that means the final price is 95% of the before price.
95% = 95/100 = 0.95
So 95% of $10,500 = 0.95 x 10500 = $9,975
To find the total percent discount, we use the percent change formula:
percent change = (difference between the values ÷ original amount) x 100
= ((12000 - 9975) ÷ 12000) x 100
= 16.875%
So the total percent discount from the car's initial price to the hoiday sale price is 16.9% to the nearest tenth of a percent.
1)
6/b-1=9/7
Add 1 to each side
6/b-1+1=9/7+1
6/b=9/7+7/7
6/b=16/7
Multiply 1/6 to each side
6/b*1/6=16/7*1/6
1/b=16/42
1/b=8/21
b=21/8 or 2 5/8
Check:
6/b-1=9/7
6/21/8-1=9/7
6*8/21-1=9/7
48/21-1=9/7
16/7-1=9/7
16/7-7/7=9/7
9/7=9/7, so x=2 5/8
2)
4/m-8=8/2
Add 8 to each side
4/m-8+8=8/2+8
4/m=8/2+16/2
4/m=24/2
4/m=12
Multiply 1/4 to each side
4/m*1/4=12*1/4
1/m=3
m=1/3
3)
5/6=7n+9/9
5/6=7n+1
7n+1=5/6
Subtract 1 to each side
7n+1-1=5/6-1
7n=5/6-6/6
7n=-1/6
Multiply 1/7 to esvh side
7n*1/7=-1/6*1/7
n=-1/42
4)
4/9=r-3/6
Add 3/6 fo each side
4/9+3/6=r-3/6+3/6
24/54+27/54=r
51/54=r
17/27=r
Hope it help!
Answer:
Yes, it is a right angle triangle
Step-by-step explanation:
Let leg lengths be y and z
Y = 2mm
Z = 2.1mm
Let x represent hypothenus
X = 2.9mm
To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)
x² = y² + z²
x² = 2² + 2.1²
x² = 4 + 4.41
x² = 8.41
Take the square root of both sides
x = √(8.41)
x = 2.9mm
Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle
Hi hope I helped, ok so first 6×7=42 and its less than 53 so ur answer is 42
Answer:
A. 
Step-by-step explanation:
No more than 110 lb total will be grilled. That means that the amount of meat that will be grilled is equal to or less than 110 lb.
The total weight is made up of the weight of the chicken legs plus the weight of the racks of ribs.
1 chicken leg weighs 1.25 lb.
x chicken legs weigh 1.25x.
1 rack of ribs weighs 7 lb.
y racks of ribs weight 7y.
The total weight of the meat is
1.25x + 7y.
That weigh must be less than or equal to 110 lb.
Answer: A.
