Water and oil are mixed in the ratio 3:5. Find the density of the mixture if the density of water is 1g/cm ^3 and that of oil is 0.8g/cm^3
Answer:
Density of mixture is 7.0 g/[tex]cm^{3}[/tex].
Step-by-step explanation:
Density of mixture = density of water in the mixture + density of oil in the mixture
Given: water and oil were mixed in a ratio 3:5
density of water is 1.0 g/[tex]cm^{3}[/tex] and that of oil is 0.8 g/[tex]cm^{3}[/tex].
Then,
density of water in the mixture = 3 x 1.0 g/[tex]cm^{3}[/tex]
= 3.0 g/[tex]cm^{3}[/tex]
Density of the volume of water in the mixture is 3.0 g/[tex]cm^{3}[/tex].
density of oil in the mixture = 5 x 0.8 g/[tex]cm^{3}[/tex]
= 4.0 g/[tex]cm^{3}[/tex]
Density of oil in the mixture is 3.0 g/[tex]cm^{3}[/tex].
So that,
Density of mixture = 3.0 + 4.0
= 7.0
Density of mixture is 7.0 g/[tex]cm^{3}[/tex].

Given:
A figure of a circle with secants intersecting inside the circle.
To find:
The value of x.
Solution:
According to the intersection theorem of secants, if two secants intersect each other inside the circle, then the angle on the intersection is the average of the intercepted arcs.
Using the intersection theorem of secants, we get
[tex]x^\circ=\dfrac{1}{2}(35^\circ+103^\circ)[/tex]
[tex]x^\circ=\dfrac{1}{2}(138^\circ)[/tex]
[tex]x^\circ=69^\circ[/tex]
[tex]x=69[/tex]
Therefore, the value of x is 69.

Leo’s dad brought home some bagels and muffins. Each bagel cost $0.90 and each muffin cost $0.80. Altogether he brought home 9 items for a total cost of $7.60.
Answer:
Leo's dad bought 4 bagels and 5 muffins.
Step-by-step explanation:
The total cost was 7.60, and had 9 items. I figured that the solution of (__ x 0.9) needed to end with 60 cents.
4 x 0.9 = 3.6
5 x 0.8 = 4.0
3.6 + 4.0 = 7.60.
Total of 9 items, adding up to 7.60.
a) josie makes fruit punch by mixing fruit juice and lemonade in the ratio 3:4, she needs to make 49 litres of punch for a party. how much of each ingredient does she need (in lires)
b) During the party josie decides tio make some more. she has 15 litres of fruit juce left and plenty of lemonade. how much extra punch can she make? (answer in letres)
c) to make the second batch of punch go further josie adds 4 more lires of lemonade. what is the ratio of fruit juice and lemonade in the second batch? (answer in ratios e.g 5:9)
Answer:
1. Josie needs 21 litres of fruit juice need 28 litres of lemonade.
2. Josie can make an extra of 35 litres of punch.
3. 5:8
Step-by-step explanation:
a) The ratio of the fruit juice to lemonade = 3:4
Total litres of punch to be made = 49
Amount of fruit juice needed = [tex]\frac{3}{7}[/tex] x 49
= 21 litres
Amount of lemonade needed = [tex]\frac{4}{7}[/tex] x 49
= 28 litres
Thus, she would need 21 litres of fruit juice need 28 litres of lemonade.
b) She has 15 litres of fruit juice left. Let the litres of punch to be made be represented by s.
[tex]\frac{3}{7}[/tex] x s = 15
s = 35
Josie can make an extra of 35 litres of punch.
c) For the second batch, she needs;
15 litres of fruit juice needs 20 litres of lemonade.
But adding 4 more litres to the lemonade makes the total litres of lemonade to be 24.
Thus the ratio of the juice to lemonade = 15:24
= 5:8
solve the following equation
please it's urgent
3a + 5b = -9 , 2a + 5b = -11
Answer:
a = 2
b = -3
Step-by-step explanation:
Here, we want to solve the two equations simultaneously
since we have the same 5b term in both, we can subtract the second equation from the first
we have this as;
3a-2a = -9 -(-11)
a = -9+ 11 = 2
Recall;
2a + 5b = -11
2(2) + 5b = -11
5b = -11-4
5b = -15
b = -15/5
b = -3

BD bisects angle ABC.
The measure of angle ABD is (2x + 12) and the
measure of angle ABC is 44º. Find the value of x.
Answer:
x = 5
Step-by-step explanation:
Given that BD bisects <ABC, it means that <ABC is divided into two equal angles, which are <ABD and <CBD.This implies that:
m<ABD = m<CBD. Therefore:
2(m<ABD) = m<ABC
Substitute:
2(2x + 12) = 44
Solve for x.
4x + 24 = 44 (distributive property)
4x + 24 - 24 = 44 - 24 (substraction property of equality)
4x = 20
4x/4 = 20/4 (division property of equality)
x = 5

400 is 75% of what number?
Answer:
534
Step-by-step explanation:
Suppose you always eat a particular brand of cookies out of the standard sized package it comes in from the store. You notice that when you eat 3 at a time, there's always 1 cookie left over. You decide when you purchase the next package, you'll eat 5 at a time, but still, there's always 1 cookie left over. Since it really isn't helpful to always have a leftover cookie, you decide to eat 7 at a time, and there are no cookies leftover. If you know there are less than 100 cookies in the package, how many cookies are there?
Answer:
There are 91 cookies in the package of cookies
Step-by-step explanation:
The given parameter for the number of cookies are;
The number of cookies left when eating 3 at a time = 1 cookie
The number of cookies left when eating 5 at a time = 1 cookie
The number of cookies left when eating 7 cookies at a time = No cookie leftover
Let 'n' represent the number of cookies in the pack, let 'a', 'b', and 'c' be the multiples of 3s, 5s, and 7s in 'n', respectively, we have;
The number of cookies in the pack, n < 100
Therefore, we have;
3·a = n - 1
5·b = n - 1
7·c = n
∴ n - 1 is a multiples of 3 and 5 less than 100 which are;
15, 30, 45, 60, 75, and 90
Therefore, the possible values of 'n' are'
n = n - 1 + 1 = 15 + 1 = 16, 30 + 1 = 31, 45 + 1 = 46, 60 + 1 = 61, 75 + 1 = 75, 90 + 1 = 91
Multiples of 7 includes;
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, and 98
Therefore, n = 91 which is the number that appear simultaneously in both search
The number of cookies in a package = 91 cookies

Answer:
Area for circle is Pr²
say 13 in from side of circle to other side, cut it in half so its going to be 6.5.Now multiply 3.141 x 6.5² and that is the area. For square multiply the length x width and the same for rectangle length x width.

Answer:
A. Hundred millions.
Step-by-step explanation:
Growing up, the easiest method I've found in terms of finding which place a number is is as follows: change the number you're looking for into a 1, change everything after it into a 0, drop everything before it, and ask yourself what that number is. That may seem a little odd, but here's some examples.
Let's say we have the number 91,582. We want to figure out what place the 5 is in. First, let's change the 5 into a 1, like so: 91,182. Next, we'll change all the numbers afterwards into 0s, like so: 91,100. Finally, we'll drop every number before the 1, leaving us with 100. Now, ask yourself what that number is. It's one hundred. That means that the 5 is in the one hundreds place.
Let's apply this to our given number. First, let's go ahead and change our 6 into a 1: 7,114,118,872. Next, let's change all the numbers after the 1 into 0s: 7,100,000,000. Finally, let's drop all numbers before our 1: 100,000,000. Our final number is one hundred million. This means that the 6 is in the one hundred millions place. Please let me know if you have any questions!
