Answer:
Step-by-step explanation:
PQS and RQS are supplementary
PQS +68=180
PQS =112
x+ 112+TSQ=180
4x=3x+TSQ
TSQ=x which means
2x+112=180
2x=68
x=34
We can measure temperature in two different common units: degrees Celsius and degrees Fahrenheit.
The variable F represents the temperature in degrees Fahrenheit that is equivalent to CCC, the temperature in degrees Celsius.
F=32+1.8CF=32+1.8CF, equals, 32, plus, 1, point, 8, C
What is the temperature increase in degrees Fahrenheit that is equivalent to a temperature increase of 10 degrees Celsius?
Answer:
Step-by-step explanation:
Thank you for asking this question. Here is your answer:
1/2 The increase in temperature by 10
10°C
Times the unit rate of the conversion function.
2/2 F
is given in slope-intercept form, so the slope of the graph is 1.8
This means the unit rate is 1.8°F / 1°C
Therefore, for 10°C
The increase in Fahrenheit is
10⋅1.8
= 18°F

Plotting Equivalent Ratios
Mr. Hendricks is plotting equivalent ratios on a coordinate plane. One of the ordered pairs is (3, 5). Which other ordered pair could he plot?
A batch of cookies is 24 cookies. It cost Courtney 134 dollars and 40 cents to make 10 batches of cookies.
How much does it cost Courtney to make 1 batch of cookies? Round to tenths places if necessary.
How much does it cost her to make 1 cookie? Round to the tenth place if necessary.
Answer:
13 dollars and 44 cents, 56 cents.
Step-by-step explanation:
134 dollars are 40 cents = 134.4 dollars.
10b = 134.4
b = 13.44
13 dollars and 44 cents
There are 24 cookies to a batch
24c = 13.44
c = 0.56.
so each cookie costs 56 cents
Answer:
13.44 to make 1 batch. 0.56 to make 1 cookie.
Step-by-step explanation:
If it cost 134.40 to make 10 batches, then you would divide that by 10 for how much it cost for 1 batch.
Then, 1 batch of 24 costs 13.44, you would divide it by 24 for the cost of 1 cookie.

Raj started with angle B and constructed angle D.
The congruent triangles are solved and the measure of HI ≅ FG and the measure of DH ≅ BF
What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the first triangle being constructed be ΔCBA
Let the second triangle being constructed be ΔDEL
Now , the measures of the corresponding sides of the congruent triangles will be in the same ratio
So , measure of HI ≅ measure of FG
And , the measure of DH ≅ the measure of BF
Hence , the ∠D is congruent to ∠B

Answer:
[tex]\huge\boxed{\sf x =28 \textdegree}[/tex]
Step-by-step explanation:
Given that,
∠IAK = 62°
∠IAK + ∠IAD = 90° (Complementary angles)
62 + ∠IAD = 90°
Subtract 62 to both sides
∠IAD = 90 - 62
∠IAD = 28°∠IAD = ∠ACB (Corresponding angles are equal)
So,
∠ACB = 28°∠ACB = ∠GCJ (Vertically opposite angles are equal)
So,
28° = x°
OR
x° = 28°[tex]\rule[225]{225}{2}[/tex]
Answer:
28 degrees
Step-by-step explanation:
If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.
--> Angle LAJ is 62 degrees
If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.
We know that in a triangle, there are three angles, and the angle measures combined equals 180.
Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.
--> 180 - 90 - 62 = 28
--> Angle BCA = 28 degrees
Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.
Angle x = 28 degrees

Zoe is doing a survey to find the time her classmates spend playing video games. She asks the following question:
Which student spends the most time playing video games?
Describe the data you would expect her to collect from this question. (5 points)
Answer:
Step-by-step explanation:
I would expect her to find out how long each classmate spends playing video games. Then, I'd expect her to use this information and put it into a bar chart so that she can compare the numbers and find the biggest one, or who spends the most time playing video games.
Here's a random example:
Let's say she has 4 classmates, Zoe, Robert, John, and Taylor.
Zoe: 2 hours on video games
Robert: 6 hours on video games
John: 1 hour on video games
Taylor: 4 hours on video games
Then, i'd put this information into a bar chart. The screenshot is a random reference of what a bar chart looks like.

The table shows the height in inches of 10 players on a college basketball team.
Answer:
A) The median is one of the values listed in the table
Step-by-step explanation:
The median is the middle number in an ordered data set. Since the number of date in the table is a even number, both 75 and 76 is the middle number. To find the median of an set of data that has an even number of sets, you just add the 2 middle numbers together and divide by 2. So like:
75+76=151
151/2=75.5
75.5 is the median but its not listed in the table, so A.

how much will you have to pay back in total if you borrowed $400 from the bank for a year at 12%
You would have to pay back $448 in total after one year.
What is the amount on the loan?The simple interest formula can be expressed as;
I = P × r × t
Where I is interest, P is principal, r is interest rate and t is time.
Given the parameters:
Principal P = $400 (the initial loan amount)
Rate r = 12% = 12/100 = 0.12
Time t = 1 year
Interest = ?
To determine the interest, we can use the above formula for simple interest:
I = P × r × t
Interest = $400 × 0.12 × 1
Interest = $48
Money to be paid back will be:
Amount = Principal + Interest
Amount = $400 + $48
Amount = $448
Therefore, the accrued amount to be paid is $448.

Answer:
30
Step-by-step explanation:
Since 5 and 6 are coprime, the least common multiple is their product, which is 30.
Answer: 30
Step-by-step explanation:
The least common multiple of two numbers, or LCM, is the smallest multiple that can divide evenly into both numbers. We can easily find the LCM by finding the primes that multiply into both numbers.
[tex]5=5\\ 6=2*3[/tex]
If there were any in common between the factorization of both numbers, we would only need to count it once. Since there weren't any, the smallest multiple of both numbers would be their product, 30.
Hence, the LCM of 5 and 6 is 30.
2 friends shared 48 pineapple equally among themselves. One of the friends sold all his pineapple each at $5.How much did he get from selling the pineapples?
Answer:
$120
Step-by-step explanation:
48 pineapples shared equally by 2 people.
48/2 = 24
Each friend got 24 pineapples.
24 × $5 = $120
Answer: $120
Answer: $120
Step-by-step explanation:
Step 1: Find how many 1 person gets (pineapples per person)
48 pineapples divided by 2 people= 48÷2= 24 pineapples each.
Step 2: Money made by 1 person
He has 24 pineapples to sell because that's how many he is supposed to receive. he sells all of them for $5 each, so the total money he makes is 5x24= $120
Checks:
120÷24= 5
the pineapples are 5 dollars each (this is correct).

Step-by-step explanation:
Hello!
We want to combine any like terms and distribute the signs properly to the terms in the parentheses.
First, remove the parentheses by distributing the signs:
[tex]-(2x - 1) + 3(x + 4) - 2(x + 2)[/tex][tex]-(2x) - (-1) + 3(x) + 3(4) - 2(x) - 2(2)[/tex]The simplified form is [tex]-x + 9[/tex].
Another way to think about the negative sign is by replacing it with -1, so essentially you are multiplying the whole parentheses by -1.
