Answer:

80

Step-by-step explanation:

.375, .525, .25 difference. 20/.25 =80

There are 80 students in the sixth grade.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

Thus, a = px, b = qx

We have been given that ratio of boys to girls in the sixth grade is 3:5. If there are 20 more girls than boys, then

Now we need to do as;

b = 20 + g

3x = 20 + 5x

x  = 10

Now The students  are 8p

8 x 10 = 80

Hence, there are 80 student.

Answer:

x = 10

Step-by-step explanation:

1. The sum of all angle measures in any triangle is equal to 180 degrees.

2. (Solving)

Step 1: Combine like terms.

Step 2: Subtract 120 from both sides.

Step 3: Divide both sides by 6.

Therefore, x = 10.

Answer:

answer is A

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

The bigger the denominator is the samller the fraction is.

Ex:[tex]\frac{1}{32}[/tex] is way smaller than [tex]\frac{1}{3}[/tex]

Answer:

smaller t= 0

larger t= 4

Step-by-step explanation:

smaller t is the t sqrd

larger t is the 4t

h(t) = t^2 + 4t + 3

h(0) = (0)^2 + 4(0) +3

0 + 0 + 3

= 3

Answer:

[tex]y=5x-13[/tex]

Step-by-step explanation:

Using the graph starting at -13 and going up 5 and over right 1 continuously, it tends to pass 2,-3 and 4,7.

Answer:

Option B (second graph)

Step-by-step explanation:

Given the linear equation in standard form, 2x - 3y = 6:

It's easier to figure out the corresponding graph by transforming the equation into its slope-intercept form, y = mx + b:

2x - 3y = 6

2x - 2x - 3y = 6 - 2x

-3y = -2x + 6

Divide both sides by -3:

[tex]\frac{-3y}{-3} = \frac{-2x+6}{-3}[/tex]

y = 2/3x - 2

Now that we have the slope-intercept form, it's easier to tell that Graph B represents the given equation because:

Therefore, the correct answer is Graph B.

The equation showing the variation of the temperature would be y=(23x) + 68.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that A chef preheats an oven. It starts at room temperature, 68°F, and heats up to 23°F per minute.

The equation will be written as:-

y = 23x + 68

Here x is the time of preheating.

Therefore, the equation showing the variation of the temperature would be y=(23x) + 68.
