Answer:
Ryder 8(3 + 5)
Step-by-step explanation:
Given expression:
24 + 40
Each friend wrote:
Chet 8(4 + 5)
= 32 + 40
Wrong
Mila 4(6 + 8)
= 24 + 32
Wrong
Sue 4(6 + 9)
= 24 + 36
Wrong
Ryder 8(3 + 5)
= 24 + 40
Correct
Of the four friends, only Ryder wrote the expression correctly
Ryder 8(3 + 5)
The students in Ms. Gonzales' fifth grade math class earned the following grades on their first test: 46, 56, 64, 64, 72, 76, 77, 82, 94, 96,99 What was the mean of the grades? (round to the nearest whole number) A. 826 OB. 75 O c. 76 OD. 64 O E 83
Answer:
75
Step-by-step explanation:
mean = average so add up all your numbers, then divide by the amount of numbers so
46 + 56 + 64 + 64 + 72 + 76 + 77 + 82 + 94 + 96 + 99 = 826
826 ÷ 11 = 75.09 (about)

Simone used 2 1/3 kilograms of flour to bake a cake . She used 4/5 kilograms of flour more to bake a second cake. How much flour did she use to bake the second cake?
Answer:
3.13 kilograms used for the second cake
Step-by-step explanation:
because the fractions have different denominators you have to multiply the denominators together to figure out what to change them too. but instead you can just figure out what the decimal for each is. 1/3 is 0.33, and 4/5 is 0.80. all you do is add these together to get 1.13. so now all you do is add 2+1.13 to get 3.13.

Answer: w = 2
Explanation: To find the slope of a line, we use the formula y = mx + b, where m is the slope and b is the y-intercept. Since there is a variable, w, we can use this formula: m = 7 + w.
We know that m, or the slope of the line, is 9. If we substitute the value of 9 into that equation... we should get 9 = 7 + w.
It's simple mathematics from here.
7 plus what is 9?? 2. That's your answer. If you need help with slope-intercept and rate of change WITHOUT variables (besides x and y, of course), feel free to let me know!!
Where did I get that 7?
Usually, we use the slope formula to find the slope of a line when we know two points on the line. But if we already know the slope of a line, we can use the slope formula to find a missing coordinate of a point on the line.
We will be using this formula: y - y₂ = m(x - x₁)
This equation is useful when we know:
one complete coordinate point (x₁, y₁)and the slope of the line (m)and we want to find the other point.
(x₁, y₁) is the known point. In our example, it's (-7,-7).
(x, y), sometimes written as (x₂,y₂), is (-6, w) and represents the missing coordinate.
EXAMPLE (SEE IMAGE):
slope (m) = 3
y − y1 = m(x − x1)
We know m, and also know that (x1, y1) = (3,2), and so we have:
y − 2 = 3(x − 3)
That is a perfectly good answer, but we can simplify it a little:
y − 2 = 3x − 9
y = 3x − 9 + 2
y = 3x − 7

Which of the following trigonometric ratios are correct?
Hi there! In this problem, you should have the knowledge of three basic Trigonometric Ratio.
sinA = opposite/hypotenusecosA = adjacent/hypotenusetanA = opposite/adjacentNow that we know three basic ratio. Let's check each choices!
sin50° = d/cThis choice is wrong because we focus on the 50° angle. When we focus on 50°, sin50° should be d/x and not d/c.
sin50° = c/xThis choice is also wrong because in ratio, it's cos50° that adjacent/hypotenuse.
tan50° = d/cThis choice is correct! As ratio states, tanA = opposite/adjacent.
tan50° = x/cThis choice is wrong. x/c is a reciprocal of cosine which is 1/cos. We call the reciprocal of cosine as secant or sec in short.
cos50° = x/dThis choice is wrong as x/d is a reciprocal of sine which is 1/sin. We call the reciprocal of sine as cosecant or cosec/csc in short.
cos50° = c/xThis choice is right by the ratio. Nothing really much to explain since we follow by ratio that is defined.
Answer
tan50° = d/ccos50° = c/xQuestions can be asked through comment.
Furthermore, tan also has its reciprocal form itself which is called cotangent also known as cot in short.
Hope this helps, and Happy Learning! :)

The figure above shows a store’s supply-demand graph for coffee makers. If the store sells $375 worth of coffee makers, which of the following is a valid possible price for them? a. $15 b. $25 c. $40 d. $55
The price of $25 is a valid possible price for coffee makers
What is a supply demand graph?A supply demand graph is a graph that shows the relationship between the supply and the demand of an item
The worth of the coffee is given as:
Worth = $375
The valid price of the coffee is calculated using:
Price = Worth/n
Where n represents the number of unit coffee
Make n the subject.
So, we have:
n = Worth/Price
This gives
n = 375/Price
When Price = 15, we have:
n = 375/15 = 25
When Price = 25, we have:
n = 375/25 = 15
When Price = 40, we have:
n = 375/40 = 9.375
When Price = 55, we have:
n = 375/55 = 6.818
Ignore the decimal results
So, we have
n = 375/15 = 25
n = 375/25 = 15
At a price of $25, the coffee maker sells less coffee than at a price of $15.
This means that they sell less to earn more
Hence, the price of $25 is a valid possible price for them
