Can someone please help me
Step-by-step explanation:
Since you have 2 straight lines we know that its 180 degrees. Now that you know that take your angle of 55 degrees and subtract it from 180, you should get 125 degrees. Since the angles are mirrored and the lines are perpendicular you can fill out the rest. To find x you know that its gonna equal 125 degrees so subtract 3 from 125 and divide by 2.

The equation used to estimate typing speed is S = (w – 10e), where S
is the accurate typing speed, w is the number of words typed in 5 minutes and e is the number of errors.
A) Ignacio can type 55 words per minute (wpm). In 5 minutes, she types 286
words. How many errors would you expect her to make?
B) If Alexis types 300 words in 5 minutes with 5 errors, what is his typing speed?
C) Johanna receives a report that says her typing speed is 65 words per minute. She knows that she made 4 errors in the 5-minute test. How many words did she
type in 5 minutes?
Answer:
a) 23 errors
b) 250 wpm
c) 105 words
Step-by-step explanation:
a) 55 = (286 - 10e)
-286 -286
-231 = -10e
e = 23. 1 or 23 errors
b) S = (300 - 10(5))
= 300 - 50
S = 250
c) 65 = (w - 10(4))
65 = w - 40
105 = w

Explanation:
3D figures can be tricky to visualize when looking at a 2D flat surface.
One way to picture this is to imagine a house. The first floor is what I've highlighted in figure 1 (see attached image below). The second floor is in figure 1, and the third floor is in figure 3.
We have 5 blocks on the first floor, 2 blocks on the second floor, and 1 block on the third floor. This is a total of 5+2+1 = 8 blocks.

Step-by-step explanation:
1. Find h(-8)
h(t) = [tex]\frac{5}{4}(4 - t)[/tex]
h(-8) = [tex]\frac{5}{4}(4 -(-8))[/tex]
h(-8) = [tex]\frac{5}{4}(4+8) =\frac{5}{4}(12)=5(3)=15[/tex]
2. What is the value of g(-3)
g(x) = 4(x - 5) + [tex]x^{2}[/tex]
g(-3) = 4(-3 - 5) [tex]-3^{2}[/tex]
g(-3) = 4(-8) + 9
g(-3) = -32 + 9
g(-3) = -23
3. Find f(10)
f(x) = 14 - 3x
f(10) = 14 - 3(10)
f(10) = 14 - 30
f(10) = -16
Answer: 1. 15. 2. -23. 3. -16. 4. 25 and 129. 5. -1/3 and 41. 6. 3.
Step-by-step explanation: Hi there! Let's get started.
For #1 we insert -8 into the function that has h(t) since the first question has h(t) function, so 4 - (-8) is 12, then multiply by 5/4 to get 15.
Keep in mind each question has a corresponding function, just look at which letter matches with which.
For question 2 we insert -3 into the x values of the g function to get -32 + 9, which is -23.
For question 3 we insert 10 to get 14-30 = -16. For #4 we have to insert 5 into g and p functions. First we do g which would equal 4(5-5) + 5^2(or 25)
to get 25. And for p function we do (5+7)^2 - 15 which is 5+7=12, 12^2+144, 144 - 15 = 129.
For #5 we do the same thing but with -9 for r and f functions, for r we do -9+13/-9-3 which equals 4/-12 which is -1/3, for f function we do 14 - -3(-9) which is 14 + 27 which equals 41. And finally, for #6 we do 3+13/3-3 which equals 16/0, but we can't divide by zero, so 3 would be the x value for #6.
Hope this helps!

Step-by-step explanation:
Expand the following:

A local grocery store makes a 9-pounds mixture of trail mix. The trail mix contains raisins,
sunflower seeds, and chocolate-covered peanuts. The raisins cost $2 per pound, the
sunflower seeds cost $1 per pound, and the chocolate-covered peanuts cost $1.50 per
pound. The mixture calls for twice as many raisins as sunflower seeds. The total cost of the
mixture is $14.50. How much of each ingredient did the store use?
Answer:
The quantity of each ingredient used:
2 pounds of sunflower, 4 pounds of raisins and 3 pounds of chocolate-covered peanuts.
Step-by-step explanation:
From the question, the total weight of the mixture is 9 pounds.
Also, the mixture calls for twice as many raisins as sunflower seeds, (that is for every 1 pound of sunflower, we have 2 pounds of raisins)
Let the weight of the sunflower seeds be s pounds
Then, the weight of the raisin will be 2s pounds
The weight of chocolate-covered peanuts will be the sum of the weights of the raisin and sunflower seeds deducted from 9 pounds, that is
9 - (2s + s) = 9 - 3s pounds
Hence, the mixture contains 9-3s chocolate-covered peanuts.
Now, from the question, the raisins cost $2 per pound, the sunflower seeds cost $1 per pound, and the chocolate-covered peanuts cost $1.50 per per pounds; and the total cost of the mixture is $14.50. Then, we can write that
$2(2s) + $1(s) + $1.5(9-3s) = $14.50
$4s + $1s + $13.5 -$4.5s = $14.50
$0.5s = $14.50 - $ 13.50
$0.5s= $1.00
s = $1.00 / $0.5
s = 2
Hence, the weight of sunflower used is 2 pounds
The weight of raisin used is 2s = 2*2 pounds = 4 pounds
and the weight of chocolate-covered peanuts is 9 - 3x = 9 - 3*2 pounds
= 9 - 6 pounds = 3 pounds
Hence, the quantity of each ingredient used:
2 pounds of sunflower, 4 pounds of raisins and 3 pounds of chocolate-covered peanuts.

bake so that she has enough cookies for each student. Answers should be based on your
estimate.

By what factor can you multiply the coordinates of smaller quadrilateral, ABCD, to get the coordinates of the larger figure, A'B'C'D'?
it would be by 2
Step-by-step explanation:
since the smaller box has the coordinates of (0,3), (2,3), (1,2), (3,2) you can multiply each number by 2 which would give you the bigger boxes coordinates which is (0,6), (4,6), (2,4), (3,2).

The factor by which quadrilateral ABCD convert to A'B'C'D' is 2.
What is the scale factor?You must specify the extent of the shape's enlargement when describing one.
The scale factor is the ratio of two dimensions such that one figure is large and another is small.
The side length of a small quadrilateral
AB = 2 units.
The side length of a big quadrilateral
A'B' = 4 units.
Factor by which A'B'C'D' is bigger than ABCD = A'B' / AB
⇒ 4/2 = 2
Hence "The factor by which quadrilateral ABCD convert to A'B'C'D' is 2".
