The time required to work at temperature of75degree celsius is 56.25 minutes
Unit rateIf a machine starts working in 45 minutes at the temperature of 60degree celsius, the amount of time worked at a temperature of 1 degree is expressed as:
Unit rate = 45/60
Unit rate = 0.75degrees celsius/minute
Determine the time it required to work at temperature of 75degree celsius
Time required = 0.75 * 75
Time required = 56.25 minutes
Hence the time required to work at temperature of75degree celsius is 56.25 minutes

Quadrilateral WXYZ is a rectangle.
If X W=3, W Z=4 , and X Z=b , find Y W .
The length of the diagonal YW of rectangle WXYZ is; 5 units.
How to find the diagonals of a rectangle?
The diagonals of a rectangle are congruent and so;
YW ≅ XZ
Thus; YW = XZ = b
Now, given the three sides of right triangle XWZ, we can solve for XZ using Pythagorean Theorem:
(XW)² + (WZ)² = (XZ)²
Plugging in the relevant values gives;
3² + 4² = b²
9 + 16 = b²
25 = b²
b = √25
b = 5
Thus, we can conclude that the length of the diagonal YW is 5 units.

Step-by-step explanation:
10 - 5/1 + 7n ≥ - 30 , simplifying left side
10 - 5 + 7n ≥ - 30

the points (0, 5) and (0, −5) are the endpoints of the diameter of a circle. the point (3, �) is on the circle, in quadrant 4. what is the value of y?
Using the equation of a circle, it is found that the value of y is -4.
Equation of the circle:
A circle is a closed curve that is drawn from the fixed point called the center, in which all the points on the curve are having the same distance from the center point of the center.
The equation of a circle with (h, k) center and r radius is given by:
(x-h)² + (y-k)² = r²
Given,
The points (0, 5) and (0, −5) are the endpoints of the diameter of a circle.
The point (3, y) is on the circle, in quadrant 4.
Here we need to find the value of y.
The center is the midpoint of them, thus:
[tex]x=\frac{0+0}{2}=0\\ y=\frac{5-5}{2}=0[/tex]
So, the midpoint is (0,0).
The diameter(twice the radius) is the distance between these two points, so:
[tex]2r=\sqrt{(0-0)^2+(5-(-5))^2}[/tex]
=> 2r = √0+100
=> 2r = √100
=> 2r = 10
=> r = 5
Thus, the equation of the circle is:
=> x² + y² = r²
Apply the values,
=> x² + y² = 5²
=> x² + y² = 25
The point (3,y) is on the circle, in quadrant 4. This means that:
Replacing x by 3, we can find the value of y.
Quadrant 4 means that y < 0.
Then:
=> 3² + y² = 25
=> y² = 25 - 9
=> y² = 16
=> y = ±√16
=> y = - 4
The value of y is -4.

question what is an expression equivalent to 6(24) using the distributive property? drag and drop the appropriate number into each box.
6(20+4) is the equivalent to 6(24) using the distributive property.
How to find an expression equivalent to 6(24) using the distributive property?The distributive Property states that it is necessary to multiply each of the two numbers by the factor before performing the addition operation when a factor is multiplied by the sum or addition of two terms. This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.
In other words, an expression of the type
A (B + C) can be resolved as A (B + C) = AB + AC in accordance with the distributive property.
This characteristic also holds for subtraction.
A(B-C) = AB-AC
given that 6(24)
now compare the 6(24) with general form of distribution property a(b+c) = ab + ac
a = 6 and b+c = 24
Consequently, we must identify two integers the sum is 24.
These numbers 20 and 4 are suitable.
so,
6(20+4) = 6(20) + 6(4)
144 = 144
Hence, the 6(20+4) is the equivalent to 6(24) using the distributive property.

The measure of angle is 24°.
We are given the two sides of the triangle as:
25 units and 10 units
Since the able that need to be found lies at 25 units side, the base side will be that only.
So, we get that:
Base side = B = 25 units
Perpendicular side = P = 10 units
We know that:
tan θ = P / B
tan θ = 10 / 25
tan θ = 2 / 5
θ = tan⁻¹ ( 2/ 5)
which will be approximately equal to
θ = 24°

Order each set of numbers from least to greatest.
8. √200, 14, 41/3
The set of numbers ordered from least to greatest is- 41/3, 14, √200.
Here, we are given a set of numbers- √200, 14, 41/3
In order to compare the numbers, we first need to convert all of them into decimal or integer numbers.
Let us analyze them one by one
1. √200
we know that √100 = 10
⇒ √200 = 10√2
√2 = 1.414
Thus, 10√2 = 14.14
2. 14
As we can clearly see 14 < 14.14
⇒ 14 < √200
3. 41/3
Dividing 41 by 3, we get-
13.66
Now, we can see that 13.66 < 14 < 14.14
⇒ 41/3 < 14 < √200
Thus, the set of numbers ordered from least to greatest is- 41/3, 14, √200.
