Answer:
7%
Step-by-step explanation:
Let x represent the percentage of water in the mix. The amount of water in the mix is ...
5%·120 +10%·80 = x·(120 +80)
14/200 = x = 7% . . . . . . . . . . . . . . simplify, divide by 200
The percentage of water in the mixture is 7%.

There are 7 unique names in a bowl. In how many orders can 2 names be chosen? Hint: The word orders
implies that each unique order of two names is counted as a possibility.
Answer:
2/7
Step-by-step explanation:
Probability=number of names chosen/total number of names
p=2/7
Here in this question order is mentioned so we will use permutation.
and the formula is P(n,r) = [tex]\frac{n!}{(n-r)!}[/tex]
What is permutation and combination ?When the order of selecting something doesn't matter we use combination and when order of selection matters we use permutation.
In the given question number of unique names (n) = 7 and we are taking 2 names at a time.So the permutation of 7 names takes 2 at a time is P(7,2) =
[tex]\frac{7!}{(7-2)!}[/tex] = [tex]\frac{7!}{5!}[/tex] = [tex]\frac{7*6*5*4*3*2*1}{5*4*3*2*1}[/tex] = 7x6 = 56.
So, the number of ways of selecting is 56.

The line joining (3, p) to (7, –4p) is parallel to the line joining (–1, –3) to (3, 7). Find p.
Answer:
p = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 7)
m = [tex]\frac{7-(-3)}{3-(-1)}[/tex] = [tex]\frac{7+3}{3+1}[/tex] = [tex]\frac{10}{4}[/tex] = [tex]\frac{5}{2}[/tex]
Parallel lines have equal slopes
Calculate the slope of the other 2 points and equate to [tex]\frac{5}{2}[/tex]
with (x₁, y₁ ) = (3, p) and (x₂, y₂ ) = (7, - 4p)
m = [tex]\frac{-4p-p}{7-3}[/tex] = [tex]\frac{-5p}{4}[/tex] = [tex]\frac{5}{2}[/tex] ( cross- multiply )
- 10p = 20 ( divide both sides by - 10 )
p = - 2

CMIIW
I can't understand with your question but I think the qustion is like ☝
The value of the expression 8 x 4² + 10 - 5 x 108 x 42 + 10 - 5 x 10 is -22,582
To calculate the value of the given expression 8 x 4² + 10 - 5 x 108 x 42 + 10 - 5 x 10.
we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.
Let's break down the steps:
Calculate the exponent: 4² = 4 x 4 = 16.
Multiply 8 by 16: 8 x 16 = 128.
Multiply 5 by 108: 5 x 108 = 540.
Multiply 540 by 42: 540 x 42 = 22,680.
Multiply 5 by 10: 5 x 10 = 50.
Now, the expression becomes: 128 + 10 - 22,680 + 10 - 50.
=-22,582
Therefore, the value of the expression 8 x 4² + 10 - 5 x 108 x 42 + 10 - 5 x 10 is -22,582

A toymaker was making trucks to sell in his
shop. He made three times as many four-
wheeled trucks as six-wheeled trucks,
He used 54 wheels altogether
How many four-wheel and
siy-wheel trucks did he make?
Answer: 9 Four Wheel and 3 6 Wheel Trucks
Step-by-step explanation:
Let FW be the four-wheel trucks and SW the six-wheel trucks.
Total wheels is 4*FW + 6*SW and is equal to 54 wheels
We know that FW = 3*SW, so substitute that into the above equation:
4*3*SW + 6*SW = 54
12*SW +6*SW = 54
18*SW = 54
SW = 3
Therefore FW = 3*3 = 9
FW 4 x 9 = 36 wheels
SW 6 x 3 = 18 wheels
Total = 54 wheels

Answer:
angle C = 78
angle D = 108
Step-by-step explanation:
the measure of angle A is 102
To find the measure of angle C
let Angle C be x
102 + x = 180 (linear pair)
x = 180 -102
x = 78
angle C = 78
angle B = 78 (vertically opposite angles are equal)
angle D = 108 (vertically opposite angles are equal)
49q²-70q+25 resolve into fractors
Answer:
(7q-5)²
Step-by-step explanation:
= 49q² - 70q + 25
= 49q² -35q -35q + 25
= 7q(7q-5) - 5(7q - 5)
= (7q-5) (7q-5)
= (7q-5)²
CMIIW
Answer:
Step-by-step explanation:
49q² -70q +25 , rewrite the first two terms as squares
(7q)² -70q + 5² , compare with a² - 2ab + b² = (a-b)²
a² - 2ab + b²
(7q)² -2(7q)(5 )+ 5², because 70q = 2*35q = 2*7*5*q
We can see that a = 7q and b=5, therefore
49q² -70q +25 = (7q -5)²
We set the equation equal to 0 to find the roots
7q-5 =0, add 5 to both sides
7q =5 , divide both sides by 7
q = 5/7 ≈ 0.714

The sun is 1.5 x 10^11 m from earth.
Express this distance with an SI prefix.
Answer:
First, we write the SI prefixed. The SI unit for distance is meters.
Kilo = 10³
Mega = 10⁶
Giga = 10⁹
Terra = 10¹²
Because our value has ten to the power of 11, we will use the closest and lowest power prefix, which is giga.
1.5 x 10¹¹ / 10⁹
= 1.5 x 10² Gm or 150 Gm
Writing in kilometers, we simply repeat the procedure except we divide by 10³ this time.
1.5 x 10¹¹ / 10³
= 1.5 x 10⁸ km
Step-by-step explanation:
First, we write the SI prefixed.
The SI unit for distance is meters.
Kilo = 10³
Mega = 10⁶
Giga = 10⁹
Terra = 10¹²
Because our value has ten to the power of 11, we will use the closest and lowest power prefix, which is giga.
1.5 x 10¹¹ / 10⁹
= 1.5 x 10² Gm or 150 Gm
Little more explanation : In scientific notation, if the exponent of 10 is positive, the number is very very large. In the metric system, very large numbers are expressed in megameters (Mm) or gigameters (Gm). Gigameters is equal to 10⁹ meters. So, in SI prefix, that would be equal to 150 Gm. In kilometers, that would be equal to:
1.5×10¹¹ m * (1 km/1000 m) = 1.5×10⁸ km

find the unknown angles
Answer:
Step-by-step explanation:
∠WZA + WZY = 180 {linear pair}
88 + ∠WZY = 180
∠WZY = 180 - 88
∠WZY = 92°
∠WXY + ∠WZY = 180 {Opposite angle in cyclic quadrilateral}
x + 92 = 180
x = 180 - 92
x = 88°
