Pure salt is made up of sodium and chloride. Each gram
of salt contains 0.393 g of sodium. About how much
sodium is in 55.7 g of pure salt?
24 g
29 g
9 g
90 g
Answer:
21.8901 g
Step-by-step explanation:
Given that:
1 gram of pure salt contains 0.393 g of sodium
1 gram = 0.393g
Gram of sodium in 55.7g of pure salt will be x
1g = 0.393g
55.7g = x
Cross multiply:
x = 55.7 * 0.393
x = 21.8901
55.7 g of pure salt will contain about 21.8901 g of sodium chloride

What do we know given from the statement above the photo? We are told <Q is congruent to <S, and QR is congruent to SR. So by given that, we have an angle (angle Q or angle S), a side (side QR or SR), and another angle (angle R), so we have ASA. I hope this helps!!
Answer:
b
Step-by-step explanation:
From the comment above the photo, what do we know? We are advised that <Q is <S, and that QR is SR-compatible. We've got a corner (angle Q or angle S), a line (side QR or SR), and a separate angle (angle R), so we have ASA. I hope that's good!!

4. A square pyramid has
measures 8 inches on each side. The height
of the pyramid is 11.5 inches. Determine the
volume of the pyramid.
volume:
Answer:
[tex]V = 245\frac{1}{3} in^{2}[/tex]
Step-by-step explanation:
The volume of a pyramid is equal to the area of the base times height divded by three so
[tex]V = \frac{A_{base} h }{3} \\V = \frac{(8^{2})(11.5) }{3} \\V = \frac{736}{3} \\V = 245\frac{1}{3} in^{2}[/tex]

Which equation represents a linear function?
A) x = y2
B) y – 2 = x2 + 5x
C) y = x3 + 1
D) 5x + 6y = 12
Answer:
D) 5x + 6y = 12
Step-by-step explanation:
x = y^2 is Not Linear (Find the degree of the equation to determine if linear.)
y - 2 = x^(2) + 5x is Not Linear (Find the degree of the equation to determine if linear.)
y = x^(3) + 1 is Not Linear (A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 3.
5x + 6y = 12 is Linear (Find the degree of the equation to determine if linear.)
What’s the answer to m/3-2m/5=1/5
Answer:
m = - 3
Step-by-step explanation:
[tex]\frac{m}{3} - \frac{2m}{5} = \frac{1}{5}[/tex]
It is much easier to work with whole numbers, compared to fractions, hence one should remove the denominator of the fraction. This can be done by multiplying by the LCM (least common multiple). In this case, it is fairly obvious that the LCM of 3 and 5 is 15. Therefore multiply the entire equation by 15.
[tex]15*\frac{m}{3} - 15*\frac{2m}{5}=15*\frac{1}{5}[/tex]
Simplify
[tex]5m-6m=3[/tex]
[tex]-m=3\\m=-3[/tex]

Jose's school is 4 km away. He walked 30 min at 5 km/hr when he realized he was running late and started running. How fast does he need to to make it to school before the bell rings in 15 minutes.
Answer:
Jose need to travel with a speed of [tex]6[/tex] Km/hr to reach school in 15 minutes before the bell rings.
Step-by-step explanation:
Total distance from home to School [tex]= 4[/tex] km
Distance travelled by Jose in first [tex]30[/tex] minutes is equal to
[tex]\frac{30}{60} * 5\\= 2.5[/tex]
Distance to travel in next [tex]15[/tex] minutes is equal to
[tex]4 -2.5 = 1.5[/tex] Km
Required speed
[tex]\frac{1.5}{\frac{15}{16} } \\= 1.5 * 4\\= 6[/tex]
Jose need to travel with a speed of [tex]6[/tex] Km/hr to reach school in 15 minutes before the bell rings.

Answer:
a) x = 12
b) right triangle
Step-by-step explanation:
a) 2x + 1 + 5x + 5 + 90 = 180
7x + 96 = 180
180 - 96 = 84
84 / 7 = 12
x = 12
b) you can tell that it is a right triangle because of the square in the corner that indicates it is a right triangle

Container X has 2 cups of water with 6 teaspoons of sugar. Container Y has 4 cups of water with 8 teaspoons of sugar. In which container is the water sweeter? A. Container x B.Container Y C. Both containers have water that is equally sweet. D. (Cannot say without tasting the water in each container).
Answer:
A) Container X
Step-by-step explanation:
X=2C:6S ratio, now reduce amount but keep the same ratio
X=1C:3S
Y=4C:8S ratio, now reduce amount but keep the same ratio
Y=1C:2S
Container X has the sweeter water because it's ratio of sugar to water is higher.
Container Y is the water sweeter.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;
Container X has 2 cups of water with 6 teaspoons of sugar.
And, Container Y has 4 cups of water with 8 teaspoons of sugar.
Now,
Since, Container X has 2 cups of water with 6 teaspoons of sugar.
Hence, The ratio of water with sugar for container X = 2 : 6
= 1 : 3
And, Container Y has 4 cups of water with 8 teaspoons of sugar.
Hence, The ratio of water with sugar for container Y = 4 : 8
= 1 : 2
Cleary, We get;
⇒ 1/3 < 1/2
So, Water in Container Y is more sweeter than X.

Ash is 4 years younger than Gary, and Oak is 5 times Gary's age. The sum of their three ages is 94. Find Gary's age. Show working out. Thanks!!
Answer:
Step-by-step explanation:
If Gary's age is 14 then
Ash is 4 years younger = 14 - 4 = 10
And Oak is 5 times Gary's age = 14 x 5 = 70
So total ages = 70 + 14 + 10 = 94
