Tony has 60$ to buy souvenirs for his grandkids at the baseball game. pennants cost $7.50 and hats cost $11.99. this relationshi

bazaltina [42]

Answer:

Option a. is correct.

Step-by-step explanation:

Given: Total amount with Tony is 60$. Pennants cost $7.50 and hats cost $11.99.

To find: inequality that represents number of pennants bought by Tony if three of tony's grand kids want hats

Solution:

p denotes number of pennants and h denotes number of hats.

As three of tony's grand kids want hats, $h=3$

Total cost of 3 hats = $3(11.99)=\$35.97$

Cost of one pennant = $7.50

According to question,

$35.97+7.50p\leq 60\\7.50p\leq 60-35.97\\7.50p\leq 24.03\\p\leq \frac{24.03}{7.50}=3.204$

Also, being number of pennants, $0\leq p$

So, inequality that represents number of pennants Tony can buy is $0\leq p\leq 3.204$

Option a. is correct.

Given: 4ABC, and BP is parallel to AC.<br> Prove: m21 + m22 + m23 = 180

Charra [1.4K]

Mathematical proofs are used to prove or disprove mathematical statements.

<h3>Mathematical theorems </h3>

The theorems to use are:

The sum of angles on a straight line is 180 degrees
Alternate angles are congruent

<h3>The proof</h3>

From the question, we have: $\triangle ABC$

This means that, ABC is a triangle

Also, we have:

BP || AC

This means that lines BP and AC are parallel

So, the following angles are congruent by alternate angle theorem

$\angle 5 \cong \angle 3$ .
$\angle 4 \cong \angle 2$

The angles on a straight line add up to 180 degrees.

So, we have:

$\angle 4 + \angle 1 + \angle 5 = 180$

By substitution, the above equation becomes

$\angle 2 + \angle 1 + \angle 3 = 180$

Rewrite the equation as:

$\angle 1 + \angle 2 + \angle 3 = 180$

Hence, the statement that $\angle 1 + \angle 2 + \angle 3 = 180$ has been proved

Determine whether the table of values below represents a linear function. If it represents a linear function, write the function

Rzqust [24]

Answer:

The equation of a linear function is:

$y = 2x+4$

Step-by-step explanation:

Given the table

x y

-10 -16

-3 -2

1 6

2 8

Determining the slope between the points (-10, -16), (-3, -2)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-10,\:-16\right),\:\left(x_2,\:y_2\right)=\left(-3,\:-2\right)$

$m=\frac{-2-\left(-16\right)}{-3-\left(-10\right)}$

$m=2$

Determining the slope between the points (-3, -2), (1, 6)

$m=\frac{6-\left(-2\right)}{1-\left(-3\right)}$

$m=2$

Determining the slope between the points (1, 6),(2, 8)

$m=\frac{8-6}{2-1}$

$m = 2$

As the slope between the points is the same. Thus, the table represents the linear function.

Using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

substituting the values m = 2 and any point let say (1, 6)

$y - 6 = 2(x-1)$

$y-6 = 2x-2$

$y = 2x-2+6$

$y = 2x+4$

Therefore, the equation of a linear function is:

$y = 2x+4$
