Answer:
The answer is 135 in 3.
Step-by-step explanation:
To find the volume of a square pyramid, first you need to find the base and height. In this case,
a = 9
h = 5
Now we use the formula (1/3 a^2 h) To find the volume.
I will use )( To show numbers being multiplied, example: 3)(4 = 12
=1/3)(9 cm^2)(5 cm
=1/3)(81 cm)( 5 cm
= 135 in. 3

2. If mZ1 = 71 degrees, find the measure of the other 7 angles.
The measure of the other 7 angles are;
m∠2 = m∠3 = 109°; m∠4 = m∠5 = m∠8 = 71°; m∠6 = m∠7 = 109°
We are given;
m∠1 = 71°
Thus;
m∠1 and m∠2 are angles that form a straight line and as such they are supplementary angles and sum up to 180°
Thus; m∠1 + m∠2 = 180°
71 + m∠2 = 180°
m∠2 = 180 - 71
m∠2 = 109°
Now, m∠2 and m∠3 are alternate angles and as such;
m∠2 = m∠3
Thus; m∠3 = 109°
Similarly,
m∠1 and m∠4 are alternate angles and as such;
m∠1 = m∠4
Thus;
m∠4 = 71°
m∠1 and m∠5 are corresponding angles and as such;
m∠1 = m∠5
Thus;
m∠5 = 71°
m∠2 and m∠6 are corresponding angles and as such;
m∠2 = m∠6
Thus;
m∠6 = 109°
Similar to how angles were gotten earlier, we can say that;
m∠5 = m∠8 = 71°
and m∠6 = m∠7 = 109°

Susan makes a purchase of $175 and is charged 7.75% for sales tax. What is the total cost of the purchase if Susan charges it on a credit card with a daily interest rate of 0.039% and pays the balance off at the end of 30 days? a. $176.17 b. $186.70 c. $190.77 d. $200.26
Answer:
C. 190.77
Step-by-step explanation: edge 2022
The required, total cost of the purchase is $190.77. Option C is correct.
What is the percentage?The percentage is the ratio of the composition of value to the overall composition of value multiplied by 100.
Here,
To calculate the total cost of the purchase, we first need to calculate the amount of sales tax and add it to the original price.
Sales tax = 7.75% of $175 = 0.0775 x $175 = $13.56
Total cost of purchase = $175 + $13.56 = $188.56
If Susan charges the purchase to her credit card and pays it off after 30 days, she will be charged interest on the outstanding balance for those 30 days. The interest rate is 0.039% per day, which is equivalent to 1.17% per month (0.039% x 30).
The interest charged on the outstanding balance after 30 days will be:
Interest = $188.56 x 1.17% = $2.20
Therefore, the total cost of the purchase, including sales tax and credit card interest, will be,
Total cost = $188.56 + $2.20 = $190.76
Therefore, the total cost of the purchase is $190.77.

After some snacks at McDonalds at Lower Bonifacio Street, Kristina drove 145 meters towards the three-way junction and turns right to reach a nearby church around Rimando Road. If the displacement between the church and McDonalds is 191.442 meters, how far did Kristina travel from the three-way junction to the church?
Answer:
125 m
Step-by-step explanation:
The path of Kristina is in the shape of a right triangle where, the perpendicular is the path from the McDonalds to the three-way junction which is 145 m and the shortest distance between the McDonalds and the church is 191.442 m.
By Pythagoras theorem
[tex]145^2+x^2=191.442^2\\\Rightarrow x=\sqrt{191.442^2-145^2}\\\Rightarrow x=125\ \text{m}[/tex]
Christina had to travel 125 m from the three-way junction to the church.
The distance Kristina travelled from the three-way junction to the church is; x = 125 meters
We are told that she drove 145 meters towards the three way junction. She now turned right to reach a nearby church around rimando road.
This means that if the distance at which she turned right is x, then x is perpendicular to 145 m.
Now, we are told that the displacement between the church and McDonalds is 191.442 meters.
The displacement means the distance from the final position to the initial position. Thus, there will form a right angled triangle with 191.442 as the hypotenuse.
Using Pythagoras theorem, we have;
x² + 145² = 191.442²
x² = 191.442² - 145²
x² = 15625.039364
x = √15625.039364
x = 125 meters

Thanks!
Answer:
Well, you look at each individual place value.
1.679 and 1.697
Compare 1 to 1. They are the same. Move on.
Compare 0.6 to 0.6. They are the same. Move on
Compare 0.07 and 0.09. They are not the same. 0.07 is less than 0.09

A group of friends eat at Jae's cafe. They have an online coupon. The costs of their main courses, before applying the coupon, are $13.99, $16.99, $19.99, and $21.99. The total cost of their drinks is $12.00. What will their bill be before tax and tip?
Bill before tax and tip will be generated by the original prices of main courses . The total bill is of $84.96
Given, prices of main course at cafe .
The total bill without applying the coupon for that we simply need to add respective costs of main course and drinks bill.
Just adding all the costs to find the bill:
= $(13.99 + 16.99 + 19.99 + 21.99 + 12)
=$84.96
Now since the question asks not to apply coupon and tip so the bill will remain as it is .

Surprising survey revealed that 32% of the 475 girls at mason Junior high school were left handed, while only 12% of the 525 boys were left handed. Which is closest to the number of left-hander girls at mason Junior high school?
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let.me solve the number of left handed girls and you then choose the closest answer to the value that I get.
Surprising survey revealed that 32% of the 475 girls at mason Junior high school were left handed. Therefore, the number of left handed girls will be:
= 32% × 475
= 32/100 × 475
= 0.32 × 475
= 152 left handed girls

Answer:
y= -2x- [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
3y+2=-6x
3y=-6x-2
y= [tex]\frac{-6}{3}[/tex]x - [tex]\frac{2}{3}[/tex]
y= -2x - [tex]\frac{2}{3}[/tex]
You isolate for y in this example by moving the 2 to the other side and then dividing the -6x and -2 by 3 to get the y by itself.
