Jeremy has $1200 in spending money for the fall semester of college. He needs to purchase car insurance at $120 for 4 months, $2
abruzzese [7]

Answer:

Jeremy Will have more than just $200 to spend on Christmas presents.

Explanation :

He has a total of $1200.

He spends a $120 for car insurance. (1)

He needs to spend $25 a week for lunch. He has to do this for 16 weeks so 25*16 = $400. (2)

He needs to spend $20 a week for entertainment. For 16 weeks that'll be 20*16 = $320 (3)

adding (1) (2) and (3)

We get Jeremy's total spending will be $840. Jeremy has $1200.

1200-840 = $360

So Jeremy will have $360 to spend on Christmas present.

Jack plotted the graph below to show the relationship between the temperature of his city and the number of ice cream cones he s
timurjin [86]

Answer:

(a) The amount of ice cream increase as temperature increases

(b)

y = 2x + 5 --- equation

y = 5 --- y intercept

m = 2 --- slope

Step-by-step explanation:

Given

See attachment for graph

Solving (a): The relationship between the variables

From the attached graph, the dots on the graph increases towards up-right direction. This implies that there is a positive correlation between the variables.

In other words;

The amount of ice cream increase as temperature increases

Solving (b): The line of best fit

First, we draw a line through the points (the line should have almost equal points on both sides; see attachment 2).

From (2), we select any 2 points on the line:

(x_1,y_1) = (15,35)

(x_2,y_2) = (0,5)

The slope (m) is:

m = \frac{y_2 -y_1}{x_2 - x_1}

m = \frac{5-35}{0-15}

m = \frac{-30}{-15}

m = 2

So, the line of best fit is:

y = m(x - x_1) + y_1

Substitute known values:

y = 2(x - 0) + 5

y = 2(x) + 5

y = 2x + 5

The y-intercept is when x=0

So, we have:

y = 2*0 + 5

y = 0 + 5

y = 5

The equation cos−1 = x can be used to determine the measure of angle BAC.
Sergio [31]

we know that

in the right triangle ABC

the value of cosine of angle x is equal to

cos(x)=\frac{AC}{AB}

we have

AC=3.4\ cm\\AB=10\ cm

substitute the values

cos(x)=\frac{3.4}{10}=0.34

Find the measure of angle x

x=cos(x)^{-1} =arc\ cos(0.34)=70.12\°

Round to the nearest whole degree

x=70\°

therefore

<u>the answer is</u>

70\°
