Membership in a digital library has a $5 startup fee and then cost $9. 95 per month memberships in a video streaming service cost $7. 99 per month with no start-up fee use vocabulary words to explain how this information could be used to write an expression for the total cost of both memberships After M months
Answer:
Step-by-step explanation:
Add the cost of the start fee with membership for 'M' months ans the video streaming service for 'M' months
Total cost = startup fee + cost of membership fee for 'M' months + cost of video streaming fees for 'M' months

Answer:
B: Acute
Please make me brainiest
Answer:
B) ∠B
Step-by-step explanation:
We'll name the given acute angle as either ∠ABC or ∠B. This is because, 'B' is the vertex of the given angle, i.e., AB & AC share the same common point → 'B'. Hence, ∠B is the correct option.

Hello! In order to solve the first problem, you need to know the properties of a rhombus.
Some basic rules that apply to the problem you should know are:
All sides of a rhombus are equal, however, a rhombus consists of two angles.Opposite angles are congruent.Adjacent angles are supplementary.Diagonals intersect each other at 90 degrees.Diagonals bisect the opposite interior angles.All angles of a rhombus will always add up to 360 degrees.To be congruent, line segments must be equal in length. The same rule applies to angles, they must be of equal measure.
This being said,
1. HT is congruent to MA
2. ST is congruent to MS
3. AMH is congruent to ATH
4. If angle MHT is 80 degrees, than angle MAT is 80 degrees as they are vertical (opposite) angles. This means they are always congruent.
5. If line MH = 9, then due to congruency AT must equal 9.
A square is 360 degrees. Every line is equal, every angle is equal.
There are four right angles in a square. A right angle equals 90 degrees.
Since every line has the same length, they are all congruent.
1. True
There are no angles less or more than 90 degrees in a perfect square.
2. False
KD and IN are not perpendicular since they do not intercept. They are parallel.
3. False
Every angle in a perfect square is 90 degrees.
4. True
You can draw out lines to get a better perception of KN and ID. They are congruent due to properties of a square.
5. True

How do I solve this?
Answer:
Given:A ∆ with an exterior angle :116° & two interior angles 7x+6 & 4x
To find :The value of angle 7x+6
Solution:we know that ,
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non adjacent interior angles of the triangle.
so,
[tex]7x + 6 + 4x= 116 \\ 11x + 6 = 116 \\ 11x = 116 - 6 \\ 11x = 110 \\ x = 110 \div 11 \\ x = 10[/tex]
so ,the measure of green angle would be
[tex]7x + 6 \\ placing \: the \: value \: of \: x \: as \: 10 \\ 7 \times 10 + 6 \\ = 70 + 6 \\ = 76[/tex]
Verification:To verify our answer ,the sum of the resultant value of green angle and 4x should be 116°(the exterior opposite angle)
so,
[tex]7x + 6 + 4x = 116 \\ 7 \times 10 + 6 + 4 \times 10 = 116 \\ 70 + 6 + 40 = 116 \\ 76 + 40= 116 \\ 116 = 116 \\ \\ hence,\: verified[/tex]
Solution:
Note that:
Green angle = 7x + 64x + 7x + 6 + (180 - 116) = 180Simplify the equation to find x.
4x + 7x + 6 + (180 - 116) = 180=> 11x + 6 + (64) = 180=> 11x + 70 = 180=> 11x = 180 - 70=> 11x = 110=> x = 110/11 = 10Substitute the value of x into the measure of the green angle.
7x + 6=> 7(10) + 6=> 76°The measure of the green angle is 76°.
Identify the symmetrical interval that includes 95% of the sample means for a population with a mean equal to 44 and a standard deviation equal to 9 using a sample size of 36
The lower bound of this interval is 51.08, and the upper bound is 58.92.
Given:
Mean = 44
Standard deviation = 9
n = 36
The formula for the confidence interval of the sample mean:
Confidence Interval = [tex]X \pm z * (\sigma / \sqrt n)[/tex]
For a 95% confidence level, the z-score is approximately 1.96.
Plugging in the values into the formula, we have:
Confidence Interval = 44 ± 1.96 * (9/ √36)
= 44 ± 1.96 * (9/ 6)
= 44 ± 1.96 * 1.5
= 44 ± 2.94
Therefore, the symmetrical interval that includes 95% of the sample means is (46.94, 41.06).

Cubic bins with closed tops are used to transport melons to the farmers market. The edge length of each bin is 1. 5 m. What is the surface area of the outside of one of the bins? Drag and drop the correct answer into the box. Response area m².
Cube has all six faces as square. The surface area of the outside of one of the bins is 13.5 m².
What is the surface area of the cube?The surface area of the cube is the sum of the area of all the sides of the cube. All the six sides of the cube are made of the same size square, therefore, the surface area of the cube is 6s², where s is the length of its single side.
As it is given that the melons are kept in cubic bins whose top is closed, therefore, the cubic bin will have all six sides, with the length of the side as 1.5m.
We know the formula for the surface area of the cube, therefore, the surface area of the cubic bin is equal to the surface area of the cube with side 1.5m,
[tex]\text{Surface area of the cube} = 6s^2[/tex]
[tex]= 6(1.5)^2\\\\= 6 \times 2.25\\\\=13.5\rm\ m^2[/tex]
Hence, the surface area of the outside of one of the bins is 13.5 m².

A store is having a sale in which all bookbags are discounted by `30\%`. Mai has a coupon for `\$5` off the regular price of one bookbag. The store first applies this coupon, and then takes `30\%` off the reduced price. If Mai pays `\$23.10` for the bookbag, what was the original price, `x`, before the sale and without the coupon?
Answer:
$35.56
Step-by-step explanation:
I think.....
;-;
The original price would be $38 before the sale and without the coupon.
Given that Mai offers a $5 off the regular price of one book bag coupon. The store first uses the discount, then deducts 30% off the lowered price.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
Let the original price would be x before the sale and without the coupon.
As per the given condition,
Since Mai pays $23.10 for the bookbag
⇒ (x -5) - 30% (x -5) = 23.10
⇒ (x -5) - 0.30(x -5) = 23.10
Apply the distributive property of multiplication,
⇒ x - 5 - 0.30x + 1.5 = 23.10
Rearrange the likewise terms and apply the arithmetic operation,
⇒ x - 0.30x = 23.10 + 5 - 1.5
⇒ 0.70x = 26.60
⇒ x = 29.60/0.70
⇒ x = 38
Therefore, the original price would be $38 before the sale and without the coupon.

Pedro sliced 27 cakes. Each chocolate cake had 7 slices and each lemon cake had 6 slices. If Pedro made 170 slices in total, how many of each type of cake did he slice?
Answer:
Step-by-step explanation:
Let number of chocolate cakes = c
Number of lemon cakes = l
Total cakes = 27
c + l = 27 ---------------(I)
Total slices = 170
7c + 6l = 170 ---------------(II)
Multiply equation (i) by (-7) and then add. So, c will be eliminated and we can find the value of l
(I) * (-7) -7c - 7l = -189
(II) 7c + 6l = 170 {Now add}
- l = -19
l = 19
Plugin l = 19 in equation (I)
c + 19 = 27
c = 27 - 19
c = 8
Number of chocolate cakes = 8
Number of lemon cakes = 19
