Answer:
Volume of pure Acid in -50- LITRES of the solution= 10- litres. Let “V”- litres of water be added, then
Therefore 10= (50+ V) x8/100 .
So 10= 4 + 8V/100
8V/100 = 10–4= 6
So V= 6 x 100/8= 600/8= 75- LITRES.
So on adding 75- litres of water to the acid solution, the percentage of acid drops to 8% .
Check: Percentage of acid in 125- LITRES of acid solution, which contain 10- LITRES if pure Acid
= 10/125 x 100= 8% .

Answer:
130356 grams.
Step-by-step explanation:
The table shown in the picture is a proportion table. What I did here was divide 34932 by 4.1. That gave me 8520. So, 1 cm³ of metal is 8520 grams. Now multiply that by 15.3.
8520/1 * 153/10
Cross-cancellation (8520 becomes 852, 10 becomes 1 (GCF: 10))
852 * 153
Multiply 852 by 153 to get 130356.
130356
15.3 cm³ of metal weighs 130,356 grams.

A triangle has side lengths 4 cm, 4 cm, and 7.5 cm. The angle measures are 20°, 20°, and 140°.
What type of triangle is this triangle?
A: acute scalene
B: obtuse scalene
C: obtuse isosceles
D: acute isosceles
Answer:
D
Step-by-step explanation:
Because two side lengths are identical it is an isosceles triangle and also at least one angle is less than 90 degrees so the answer would be an acute isosceles triangle.

Answer: Yellow flowers 3 1/3 And red flowers 7
Step-by-step explanation:
So you take 3 and put into 1/3. You get 3 1/3 because if you multiply them together you get 21 and there's 21 yellow flowers in total. Then for "R" (red flowers) you would divide 21 by 3 (the reason you divided it by 3 is because there's 3 times the number of red flowers.) you would get 7.
Yellow Flowers: 3 1/3
Red Flowers: 7
1/7 / 4 as a fraction
1/7 divided by 4 is equal to 1/28.
Given that a fraction, we need to make it in proper fraction,
To divide fractions, you need to follow a specific rule. To divide one fraction by another, you multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of a fraction is obtained by interchanging the numerator and the denominator.
In this case, you have the fraction 1/7 divided by 4. To find the result, we can express 4 as a fraction with a denominator of 1: 4 can be written as 4/1.
Now, we can multiply the first fraction (1/7) by the reciprocal of the second fraction (4/1):
(1/7) x (1/4)
To multiply fractions, you simply multiply the numerators together and the denominators together:
(1 x 1) / (7 x 4)
The result is:
1/28
Therefore, 1/7 divided by 4 is equal to 1/28.
