Gala.
12.8 * 1.35 = 17.28
Honeycrisp.
9 * 1.68 = 15.12

7.4 * 1.15 = 8.51
17.28 + 15.12 + 8.51 = 40.91
Problem 16)
(area1) + (area2) + (area3) = (total area)
(1.25*4.38) + (1.36*2.15) + (1.14*3.55) = x
5.475 + 2.924 + 4.047 = x
12.446 = x

Fill in the table using this function rule y = 4 + 5x
Step-by-step explanation:
bruh ,come on this was so easy
The value of y using this function rule y = 4 + 5x is 19,29,34 and 49.
We are given that;
The function y=4+5x
Now,
To fill in the table using the function rule y = 4 + 5x,
we need to substitute each value of x into the rule and calculate, the corresponding value of y. For example, when x = 3, we get:
y = 4 + 5x
y = 4 + 5(3)
y = 4 + 15
y = 19
We can repeat this process for the other values of x and fill in the table as follows:
| x | y |
| 3 | 19|
| 5 | 29|
| 6 | 34|
| 9 | 49|
Therefore, by the function answer will be 19,29,34 and 49.

Find the probability P(z < 0.37) using the standard normal distribution.
Answer:
0.6443
Step-by-step explanation:
Given the that:
P(Z < 0.37) ; using a standard normal distribution :
The probability can be obtained using several methods :
Using a standard normal distribution table ;
P(Z < 0.37) = obtain the value at the intersection where 0.3 is on the vertical axis and 0.07 on the horizontal axis of the Z distribution table
Hence,
P(Z < 0.37) = 0.6443
Lorena's bank will loan money to customers if they overdraw their accounts by less than 100$. (To overdraw an account means to have the account balance fall below zero.) Lorena started out with a balance of $13.00 and made a withdrawal from her account of $81.50.
Answer:
a. POSITIVE NUMBER mean availability of money
NEGATIVE NUMBER mean Overdrawn
ZERO mean unavailability of money
b. YES
Step-by-step explanation:
a. Based on the information given the POSITIVE NUMBER mean the AVAILABILITY of some amount of money
A NEGATIVE NUMBER on the other hand mean OVERDRAWN which means that the customer account balance fall below Zero amount
ZERO mean UNAVAILABILITY OF MONEY
b. YES. Based on the information given if Lorena's final account balance has the amount of -$68.50 the bank will loan her reason been that we were told that the bank will give loan to their customers if they overdraw their accounts by less than the amount of $100 in which case Lorena's final account balance has the amount of -$68.50 which is less than $100. Hence the bank will loan her .

At the flag shop, for every 13 stripes there are 50 stars. If there are 10,000 stars, how many more stars are there than stripes?
Answer: 7,400
Step-by-step explanation:
First, we need the values of stars and stripes. So, let's start with the 50 stars. If there are 10,000 stars, we need to divide 10,000 by 50 to see how many sets of the 13 stripes th ÷ere are.
10,000 ÷ 50 = 200 sets of stripes.
We know that each set of stripes has 13 stripes, and there are 50 sets.
We will now multiply 13 with 20, to finf the total number of stripes:
13 x 200 = 2,600 stripes.
But WAIT! We aren't done yet!
We need to subtract 2,600 from 10,000 so that we can find how many more stars are there than stripes.
10,000-2,600 is 7,400

Find all real and imaginary solutions to the equation.
x^3-2x^2+16x-32=0
Answer:
The solution of [tex]x^3-2x^2+16x-32=0[/tex] is [tex]\mathbf{x=2,x=4i,x=-4i}[/tex]
So, the real solutions is: x = 2
Imaginary solutions are : x = 4i, x = -4i
Step-by-step explanation:
We need to find real and imaginary solutions to the equations [tex]x^3-2x^2+16x-32=0[/tex]
First of all we will make groups
[tex](x^3-2x^2)(+16x-32)=0[/tex]
Finding common terms from the groups
[tex]x^2(x-2)+16(x-2)=0\\(x-2)(x^2+16)=0[/tex]
Now we know that if ab=0 then a=0 , b=0
[tex]x-2=0, x^2+16=0\\Simplifying:\\x=2, x^2=-16\\Taking\: square\: root\\x=2,\sqrt{x^2}=\sqrt{-16}\\x=2, x=\pm\sqrt{-16}\\x=2,x=\m\sqrt{-1}\sqrt{16} \\We\:know\:\sqrt{-1}=i \:and \sqrt{x} \:\sqrt{16}=4 \\x=2,x=\pm4i\\x=2,x=4i,x=-4i[/tex]
The solution of [tex]x^3-2x^2+16x-32=0[/tex] is [tex]\mathbf{x=2,x=4i,x=-4i}[/tex]
So, the real solutions is: x = 2
Imaginary solutions are : x = 4i, x = -4i

You and a friend go to tacos for lunch. You order two burritos and five tacos and your total bill is $16. Your friend's bill is $15 for three burritos and three tacos. How much does a burrito cost? How much does a taco cost?
Answer:
Burrito = $3
Taco = $2
Step-by-step explanation:
Let b represent the cost of burrito
Let t represent the cost of taco
2b + 5t= 16.......equation 1
3b + 3t = 15.......equation 2
Multiply equation 1 by 3 and equation 2 by 2
6b + 15t= 48
-
6b + 6t = 30
9t= 18
t = 18/9
t = 2
Substitute 2 for t in equation 1
2b + 5t= 16
2b +5(2) = 16
2b + 10= 16
2b = 16-10
2b = 6
b = 6/2
b= 3
Hence the price of burritos is $3 and the price of taco is $2

The value of x as evident in the task content is; 14 and hence, the measure of angles m<DEC and m< CEF are; 142° and 38° respectively.
What are the justification s for the statements as indicated in the task content?It follows from the task content that the justifications of the statements are to be indicated.
On this note, the justifications are as follows;
m<DEF = 180°; The measure of angle on a line is 180°.m<DEC + m<CEF = 180; The algebraic sum of angles on a straight line is; 180°.(11x -12) + (2x +10) = 180; Substitute the given expressions for the angles DEC and CEF respectively.13x - 2 = 180; Collect like terms.13x = 182; Add 2 to both sides of the equation.x = 14; Divide both sides of the equation by 13.Hence, the measure of angle; m<DEC = 11x -12.
= 11(14) - 12
= 142°.
Ultimately, the measure of angle m<CEF is;
m<CEF = 180 -142
m<CEF = 38°.

Please I need help on this problem!
What is the value of x?
Answer:
x=32
Step-by-step explanation:
1. Find the angle next to the 122
Since it is a 180 degree total angle, you subtract 180-122 to get 58 degrees
2. You know two out of the 3 angles now because the square indicates a 90 degree angle. So you add 90 + 58 = 148
3. Since the total amount of degrees in a triangle is 180, you subtract 180-148 to get 32 degrees
Hope this helps! Please give me brainliest!
Answer:
x+90=122°[exterior angle is equal to the sum of two opposite interior angle]
x=122-90=32°
