BK / QZ = 45/27 ; substitute whit what you see in the picture
(4x+1) / (2x+7) = 45/27 ; cross multiply
27( 4x+1) = 45( 2x+7) ; distribute
108x + 27 = 90 x + 315; subtract 90x and 27 from both sides
108x -90x = 315 -27; combine like terms
18x = 288; divide both sides by 18
x=16
BK = 4* 16 +1 = 65

From Sine rule :
a/sinA = b/sinB
let a = missing side
a/sin40= 10/sin60
cross multiply
a* sin60 = 10 * sin40
a = 6.4278/sin60

Can you find X? Show how did u find
Answer:
x=90°
Step-by-step explanation:
As in the angle, there is a box giving us info that x has to be 90°.
But to be sure that there is no mistake we have to do the following:
Look at all the other angles (see what kind of angles they are).Add all the angles up to 360°( in this case as the angle we are looking for is on a straight line which gives straight line=180°).Checking and comparing the two answers.So we are looking at the surroundings of angle x (which is on a straight line) we see that it is a right angle and look at the angle on the same line is a right angle too.
The equation right angle=90° helps us see that because there are two right angles on a 180° line (90°+90°+180°).
Therefore the answer is:
x=90°

PK has endpoints at P(6,-3) and K(3,-9). How long is PK
Answer:
\(d=\sqrt{45}\), or \(d=3\sqrt{5}\), or about 6.7
Step-by-step explanation:
[] We can use the distance formula to solve.
-> \(d=\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1})^{2 } }\)
-> P(6, -3) will be point one
-> P(3, -9) will be point two
[] Plugging in and solving:
\(d=\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1})^{2 } }\)
\(d=\sqrt{(3 -6)^{2} +(-9--3)^{2 } }\)
\(d=\sqrt{(3 -6)^{2} +(-9+3)^{2 } }\)
\(d=\sqrt{(-3 )^{2} +(-6)^{2 } }\)
\(d=\sqrt{9 +36 }\)
\(d=\sqrt{45}\)
\(d=3\sqrt{5}\)

What do you mean by an Equation?Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.
It displays the similarity of the connections between the phrases on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.
Given data ,
Let the number of days of frog food the zookeeper has be A
Now , the value of A is
The number of cups of frog food she has = 3 cups
The number of cups of frog food she feed every day = ( 1/4 ) cups per day
Now , the equation is
A = number of cups of frog food she has / number of cups of frog food she feed every day
On simplifying the equation , we get
The number of days of frog food the zookeeper has A = 3 / ( 1/4 )
The number of days of frog food the zookeeper has A = 3 x 4
The number of days of frog food the zookeeper has A = 12 days
Hence , the number of days is 12 days

The length of a rectangle is 6 inches longer than it is wide. If the area is 160 square inches, what are the dimensions of the rectangle?
Answer:
L = 16
w = 10
Step-by-step explanation:
Givens
Area = 160 sqr inches
width = x
length = x + 6
Equation
Area = L * w
Solution
Substitute in the equation all of the givens.
160 = x(x + 6) Remove the brackets
160 = x^2 + 6x Subtract 160 from both sides.
160-160 = x^2 + 6x - 160
0 = x^2 + 6x - 160
This equation factors. Turn it around first
x^2 + 6x - 160 = 0
(x - 10)(x + 16) = 0
Answer
x (width) = 10
x + 16 = 16
Answer:
The length is 16 inches and the width is 10 inches.
Step-by-step explanation:
Which correctly shows the substitution step for the system?
y = x - 4
-4x - 6y = -16
O x-4 = -4x-6y
-4(x-4) - 6y = -16
O-4x-6(x-4) = -16
6y = x - 4
The solution to the system of equations is x = 4 and y = 0. In summary, the correct substitution step for the system is: -4x - 6(x - 4) = -16 .C answer is correct
To solve the given system of equations:
1) y = x - 4
2) -4x - 6y = -16
We can use the substitution method to eliminate one variable and solve for the other.
Step 1: Solve the first equation (1) for y in terms of x.
y = x - 4
Step 2: Substitute the expression for y from equation (1) into equation (2).
-4x - 6(x - 4) = -16
Step 3: Simplify and solve for x.
-4x - 6x + 24 = -16
-10x + 24 = -16
-10x = -16 - 24
-10x = -40
x = -40 / -10
x = 4
Step 4: Substitute the value of x back into equation (1) to solve for y.
y = 4 - 4
y = 0
Therefore, the solution to the system of equations is x = 4 and y = 0.
In summary, the correct substitution step for the system is:
-4x - 6(x - 4) = -16
By substituting the expression for y from equation (1) into equation (2) and simplifying, we obtain the equation -4x - 6y = -16, which can be further solved to find the values of x and y. C answer is correct

The solution is, the slope of the line in the graph is 5/7.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
from the given graph, we get,
the line is passing through the points ( 0,0) and, (5,7).
now, we know that
slope of a line is,
m = x1 - x2 / y1 - y2
so, we have,
here,
Slope(m) = 5-0/7-0
= 5/7
Hence, The solution is, the slope of the line in the graph is 5/7.

The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 40 mm
9514 1404 393
Answer:
8000π mm^3/s ≈ 25,133 mm^3/s
Step-by-step explanation:
The rate of change of volume is found by differentiating the volume formula with respect to time.
V = 4/3πr^3
V' = 4πr^2·r'
For the given numbers, this is ...
V' = 4π(20 mm)^2·(5 mm/s) = 8000π mm^3/s ≈ 25,133 mm^3/s
_____
Additional comment
By comparing the derivative to the area formula for a sphere, you see that the rate of change of volume is the product of the area and the rate of change of radius. This sort of relationship will be seen for a number of different shapes.
The base area of a swimming pool is 192m³.the Dept of the swimming pool is 1.8cm.find the volume of the water the swimming pool can hold. please answer as soon as possible and please follow ❣️
The swimming pool can hold a volume of 3.456 cubic meters of water.
The volume of water that the swimming pool can hold can be calculated by multiplying the base area of the pool by its depth. In this case, the base area is given as 192 m² and the depth is 1.8 cm.
However, it is important to note that the depth should be converted to meters before performing the calculation.
To convert 1.8 cm to meters, we divide it by 100 (since there are 100 centimeters in a meter):
Depth = 1.8 cm ÷ 100 = 0.018 m
Now we can calculate the volume of water using the formula:
Volume = Base Area × Depth
Substituting the given values, we get:
Volume = 192 m² × 0.018 m = 3.456 m³
Therefore, the swimming pool can hold a volume of 3.456 cubic meters of water.
In the explanation, we use the formula for calculating the volume of a rectangular prism, which is given by multiplying the base area by the depth. We convert the depth from centimeters to meters and then substitute the given values into the formula to find the volume of water that the swimming pool can hold, which is 3.456 cubic meters.
