Haywood is wrong because he collected 1,250 signatures in 15 days not 1250 signatures.

Given that, Haywood collects 85 signatures each day for a petition.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Number of signatures Haywood collected in 15 days is

85×15=1275

Since, Haywood said has collected 1,250 signatures in 15 days

So, Haywood is wrong

Therefore, Haywood is wrong because he collected 1,250 signatures in 15 days not 1250 signatures.

The given observations suggest that the increase in population is directly proportional to the number of children born and the number of surviving children.

According to the question,

We have the following information:

An article in the New York times noted that the human population has shown a significant increase in height. when the relationship of height to reproductive success in humans was examined across three decades (1935-1967), height had a positive correlation to the number of children born and the number of surviving children.

It means if the number of children born and the number of surviving children is more then the population will also increase.

In other words, it can be said population is directly proportional.

Hence, the given observations suggest that the increase in the population is directly proportional to the number of children born and the number of surviving children.

By the equations, he should make 70 whole wheat bread that would earn a profit of $105 that is maximum he can earn with the given amount of flour and egg.

simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution. A group of two or more equations that share the same variables is known as a system of equations. A set of values for a variable that simultaneously satisfy each equation is the solution to a system of equations. When there are multiple unknowns and there is sufficient data to set up equations in those unknowns, systems of equations are used to solve applications. In general, we need sufficient information to construct equations in the n unknowns.

Here,

Let x be light whole wheat and y be the regular whole wheat.

given,

A loaf of light whole wheat bread requires 2 cups of flour and 1 egg.

A loaf of regular whole wheat bread requires 3 cups of flour and 2 eggs.

The bakery has 90 cups of flour and 80 eggs on hand.

So the system of equation will be,

2x+3y=90

x+2y=80

multiply the second equation by 2,

2x+4y=160

2x+3y=90

subtract the equations,

y=70

by this,

x=-60

So by this he should make 70 whole wheat bread that will make him earn a profit of,

=70*1.5

=$105

According to the calculations, he should produce 70 loaves of whole wheat bread for a profit of $105; this is the most he can make with the supplied quantities of flour and egg.

Answer:

25.4 L

Step-by-step explanation:

Charles's Law

[tex]\sf \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\quad \textsf{(when pressure is constant and temperature is in kelvin)}[/tex]

where:

Given:

Convert Celsius to kelvin.

Kelvin = Celsius + 273.15

[tex]\implies \sf T_1= 25 + 273.15 = 298.15 \;K[/tex]

[tex]\implies \sf T_2 = 30 + 273.15 = 303.15\; K[/tex]

Substitute the given values into the formula:

[tex]\implies \sf \dfrac{25}{298.15}=\dfrac{V_2}{303.15}[/tex]

[tex]\implies \sf V_2 =303.15 \cdot \dfrac{25}{298.15}[/tex]

[tex]\implies \sf V_2 =\dfrac{7478.75}{298.15}[/tex]

[tex]\implies \sf V_2 =25.41925205...L[/tex]

Therefore, the volume of air in the tire if the temperature increases to 30.0 °C is 25.4 L (nearest tenth).

The value of x is 1.94 units approximately.

Since the triangle is equilateral and each side is [tex]\sqrt{10}[/tex].

we know that, in equilateral triangle base is bisected by the perpendicular drawn from the opposite vertex.

So here for one small triangle by Pythagoras theorem,

[tex]x^2+(\frac{\sqrt{10}}{2})^2=(\sqrt{10})^2\\x^2+\frac{10}{4}=10\\x^2=10-\frac{10}{4}=\frac{30}{4}=\frac{15}{2}\\x=\frac{\sqrt{15}}{2}\approx1.94[/tex]

Hence the value of x is 1.94 units approximately.

If we need the Gold Cup a better value, then required inequality is:

Solve it for x:

Answer:

Inequality = 10 + 0.25x < 25

The value of x = x < 60

Step-by-step explanation:

Now we have to,

→ find inequality used to solve for x.

Then the inequality will be,

→ $10 + 0.25x < $25

→ 10 + 0.25x < 25

Required value of x will be,

→ 10 + 0.25x < 25

An equation to model the situation: h = 30000 - 2000t

the altitude of the plane after 5 minutes is  20000 feet

In this question, an airplane 30,000 feet above the ground.

It begins descending at a rate of 2,000 feet per minute.

We need to write an equation to model the situation. Also, we need to find

the altitude of the plane after 5 minutes.

Let h be the altitude of plane after t hours.

So, we get an equation,

h = 30000 - 2000t

For t = 5 minutes,

h = 30000 - 2000(5)

h = 30000 - 10000

h = 20000 feet

Therefore, an equation to model the situation: h = 30000 - 2000t

The measure of angle P as well as angle Q is 76.825. Hence, option D is correct.

When two lines converge at a point, they produce an angle. The word "angle" refers to the length of the "gap" between these two rays. The symbol is used to denote it.

Radians, a unit of roundness or rotation, and degrees are the 2 most common units used to measure angles. In daily life, angles are present.

As per the given data from the question,

Angle P and Q are congruent and,

Angle, ∠R = 26.35°

Suppose ∠P = a

The sum of all the three angles of a triangle is 180°.

x + x + 26.35° = 180°

The area of the triangle will be 60ft².

What is are of triangle?

The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.

Now using the Pythagoras theorem we can find out the length of the other wall

b²+p²=h²

So here h=13ft and b=5ft

p²= h²-b²

  = 13²-5²

  =169-25

p = √144 = 12ft

So the area of the trinagle is = 1/2*b*p

1/2(10*12)= 60ft²

The equivalent value to the expression 18.9 x [(2 x 2.7) - 4.6] - 2² is given by the following option:

C. 11.12.

The equivalent value to an expression is given by the solution to the expression.

The expression in this problem is given as follows:

18.9 x [(2 x 2.7) - 4.6] - 2²

The brackets take precedence, hence the first operation to be solved is of:

(2 x 2.7) - 4.6

The parenthesis take precedence relative to the subtraction, hence:

(2 x 2.7) - 4.6 = 5.4 - 4.6 = 0.8.

Then the expression is given by:

18.9 x [(2 x 2.7) - 4.6] - 2² = 18.9 x 0.8 - 2².

The square takes precedence, hence:

18.9 x 0.8 - 4.

Then the multiplication takes precedence, which means that the equivalent result is of:

18.9 x 0.8 - 4 = 15.12 - 4 = 11.12.

Seeing the value in option C is correct as it tells the value of thousandths is greater than or equal to 5 is correct as 9 is in thousandths place and is greater than 5.

Increasing the value in the hundredth which is zero to one and dropping the digit in the thousandth place is correct as it makes the value 213.71.
