Answer:
Total Amount spent on all the cards = $ 42.3
No of cards = 16 .
Step-by-step explanation:
The cost is calculated by multiplying the number of items with their costs. As we have different costs for each card we will add the costs of different cards to get the total costs.
Janet buys 3 postcards for $1.05.
Janet spends 3* $1.05= $ 3.15
Rosie buys five postcards for $1.75
Rosie spends 5 * $ 1.75= $ 8.75
Tanya buys eight postcards for $3.80
Tanya spends 8 * $3.80 = $ 30.4
Total Amount spent on all the cards = $ 3.15+$ 8.75+$ 30.4= $ 42.3
No of cards = 3 + 5+ 8= 16 cards were bought .

The function y=0.75x + 2 represents the cost y (in dollars) of an ice cream sundae with x toppings. A sundae comes with 1, 2, 3, or 4 toppings. Identify the independent and dependent variables, the domain, and the range.
Answer:
Please check answer for explanation
Step-by-step explanation:
The independent variable is x
The dependent variable is y
The domain is the range of values of x
That will be 1-4
Now let’s get the range, the range just represent the y-values of the terms in the domain
at x = 1
y = 0.75(1) + 2 = 2.75
at x = 4
y = 0.75(4) + 2 = 3 + 2 = 5
The range is 2.75 to 5
If CE bisects ZBCD and if m ZBCE = 3x - 6
and mZECD = 2x + 11, find mZBCD. Is
ZBCD acute, right, or obtuse?
Answer:
m∠BCD = 90°
∠BCD is a right angle
Step-by-step explanation:
If a ray bisects an angle, that means it divides the angle into two equal parts in measure
∵ Ray CE bisects ∠BCD
→ Means divide it into two angles BCE and ECD which equal in measures
∴ m∠BCE = m∠ECD = [tex]\frac{1}{2}[/tex] m∠BCD
∵ m∠BCE = 3x - 6
∵ m∠ECD = 2x + 11
→ Equate them to find x
∴ 3x - 6 = 2x + 11
→ Add 6 to both sides
∵ 3x - 6 + 6 = 2x + 11 + 6
∴ 3x = 2x + 17
→ Subtract 2x from both sides
∵ 3x - 2x = 2x - 2x + 17
∴ x = 17
∵ m∠BCE = [tex]\frac{1}{2}[/tex] m∠BCD
→ Substitute x in the measure of ∠BCE to find it, then use it to
find m∠BCD
∵ m∠BCE = 3(17) - 6 = 51 - 6
∴ m∠BCE = 45°
∵ 45 = [tex]\frac{1}{2}[/tex] m∠BCD
→ Multiply both sides by 2
∴ 90 = m∠BCD
∴ m∠BCD = 90°
→ The measure of the acute angle is less than 90°, the measure of
the obtuse angle is greater than 90°, and the measure of the
right angle is 90°
∴ ∠BCD is a right angle

The sum of two integers is -27. If one of them is 260. find the other.
I NEED THIS ASAP!!!
PLSSSSSSSSS
Answer:
-287
Step-by-step explanation:
If x + y = z, then z - y = x and z - x = y. Since 260 + x = -27, then -27 - 260 = x.
You can change the signs for a moment but you need to change them back at the end. 27 + 260 = 287, flip the signs, -27 - 260 = -287.

Find the greatest common factor of 35 and 26
Answer:
1
Step-by-step explanation:
The factors of 26 are:
1, 2, 13, 26
The factors of 35 are:
1, 5, 7, 35
The common factors are:
1
The required greatest common factor(GCF) of 35 and 26 is 1.
What is the Greatest Common Factor (GCF)?The greatest Common Factor is defined as the greatest number that is a factor of both numbers when two numbers are involved.
A number that divides into another number completely is said to be a factor.
The numbers are given in the question, as follows:
35 and 26
We have to determine the greatest common factor of 35 and 26
Prime factorization of the numbers:
35 = 5 × 7
26 = 2 × 13
GCF(35, 26)
= 1
Hence, the required greatest common factor of 35 and 26 is 1.

The pre-image and image of what transformation are not congruent?
O A. dilation
O B. reflection
O C. translation .
O D. rotation
Answer:
Option A
Step-by-step explanation:
Options B, C, and D are examples of ridged transformations. Ridged transformations are transformations that keep the pre-image and image congruent.
A dilation would change the actual size of the pre-image to make the image, so they would be not congruent in a dilation.
Hope this helps.
The correct options are Reflection, Translation and Rotation.
What is transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
Reflection, Translation and Rotation are examples of rigid transformations, and we know that a rigid transformation is a transformation that doesn't change the size or shape of a geometric figure, a special kind of transformation that doesn't change the size or shape of a figure.
There are three different types of transformations: translation, reflection, and rotation.
Whereas,
A dilation would change the actual size of the pre-image to make the image, so they would be not congruent in a dilation, it can enlarge or shrink the image.
Hence, Reflection, Translation and Rotation are the transformation which preserve the preimage.

Maya is taking her friends to a concert. Each ticket costs
$25, and souvenir T-shirts are $12 each. There is a $4
service fee for the entire purchase. She has $130. If she
buys 3 tickets, what is the maximum number of T-shirts
she can buy?
If x = number of tickets and y= number of T-shirts, which of the following
inequalities could you use to answer the problem?
Answer:
C. 25x+12y+4≤ 130
Step-by-step explanation:
Each ticket cost $25, so x would be the number of tickets she has to buy.
25x
Each T-shirt cost $12, so y would be the number of T-shirts she can buy.
12y
And since there is an service fee for the entree purchase, that's another $4.
+4
The cost of everything has to be less than $130, so the equation would be:
25x+12y+4≤ 130

Which of the following rules describes the function graphed below? On a coordinate plane, points are at (1, 5), (2, 4), (3, 3), (4, 2). a. Output = Input c. Output = 5 · Input - 4 b. Output = Input - 4 d. Output = 6 - Input Please select the best answer from the choices provided A B C D
*see attachment
Answer:
D. Output = 6 - Input
Step-by-step explanation:
The output is the y-value, while the input is the x-value. The coordinates are represented as (x, y), and are graphed in the figure attached below.
Let's consider the function and see which rule best describes the function.
Considering the point (1, 5), the rule, output = 6 - input, applies.
Let's check it out:
Output is 5, input is 1. Substitute 1 as input into the rule, Output = 6 - input, and see if it would give you 5 as output:
Output = 6 - 1
Output = 5
If you try another coordinate pair of the function, the same rule will apply.
Therefore, the best answer is D. Output = 6 - Input
