Mark has 10 pens. Kate has 5 times as many pens as Mark.
Which equation below answers how many pens Kate has? (y = number of Kate's pens
10 = 5 × y
10 = 5 + y
y = 5 × 10
y = 10 ÷ 5
Answer:
The third one, y = 5 x 10
Step-by-step explanation:
y = number of Kate's pens, 5 = how many times more pens Kate has than Mark, and 10 = how many pens Mark has.

Aan angle in quadrant I, the value of sin[tex]\theta[/tex] is [tex]\rm Sin \theta=\dfrac{\sqrt{14} }{5}[/tex].
What is the sin theta?Sin theta is defined as the ratio of perpendicular and hypotenuse.
The given equation is;
[tex]\rm Cos\theta=\dfrac{\sqrt{11} }{5}[/tex]
The cos[tex]\theta[/tex] is given by;
[tex]\rm Cos\theta=\dfrac{Base}{hypotenuse}[/tex]
By applying Pythagoras theorem the value of base is;
[tex]\rm (5)^2=Perpendicular^2+ (\sqrt{11} )^2\\\\ Perpendicular^2= 25-11\\\\ Perpendicular^2=14\\\\ Perpendicular =\sqrt{14}[/tex]
The value of sin[tex]\theta[/tex] is;
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypoteunse}\\\\Sin \theta=\dfrac{\sqrt{14} }{5}[/tex]
Hence, the value of sin[tex]\theta[/tex] is [tex]\rm Sin \theta=\dfrac{\sqrt{14} }{5}[/tex].

Answer:
x = 3
Step-by-step explanation:
Formula
CE * DE = AE * BE
Notice how the chords cut each other. Also notice how the segments are equated. See the givens.
Givens
CE = 3
DE = x + 11
AE =x+3
BE = 7
Solution
3*(x + 11) = 7(x + 3) Remove the brackets
3x + 33 = 7x + 21 Subtract 21 from both sides
3x + 33 - 21 = 7x Combine the left
3x + 12 =7x Subtract 3x from both sides
12 = 7x - 3x
12 = 4x Divide by 4
12/4 = 4x/4
x = 3

f(x) = |7x + 1|– 8
g(x) = -2
Find (f - g)(2).
O A. (f – g)(x) = |7x] – 5
B. (f - g)(x) = 172 – 7 + 2
O c. (f – g)(x) = 17x +11 – 6
O D. (f - g)(x) = 17x – 5||
Answer:
f-g)(x)= | 7x + 1 | -6 Is correct
Step-by-step explanation:
Functions f(x) and g(x) are illustrations of composite functions.
The value of (f - g)(x) is |7x + 1| - 6
The functions are given as:
[tex]\mathbf{f(x) = |7x +1|- 8}[/tex]
[tex]\mathbf{g(x) = -2}[/tex]
The function (f - g)(x) is calculated using:
[tex]\mathbf{(f - g)(x) = f(x) - g(x)}[/tex]
So, we have:
[tex]\mathbf{(f - g)(x) = |7x + 1| - 8 - (-2)}[/tex]
Remove bracket
[tex]\mathbf{(f - g)(x) = |7x + 1| - 8 +2}[/tex]
Simplify
[tex]\mathbf{(f - g)(x) = |7x + 1| - 6}[/tex]
Hence, the value of (f - g)(x) is |7x + 1| - 6

Một ủy ban an toàn kiểm tra ngẫu nhiên 900 công nhân xây dựng trong thời gian làm việc, thấy có 48 công nhân không mang mũ bảo hộ. Hãy ước lượng tỷ lệ công nhân không mang mai bảo hộ trong thời gian làm việc với độ tin cậy 98%
Answer:
The percentage of workers not wearing the helmets is 5.3 %.
Step-by-step explanation:
A safety committee randomly examined 900 construction workers during their work, and found that 48 workers were not wearing helmets. Estimate the percentage of workers who do not wear protective masks during their working time with 98% confidence
total workers = 900
Not wearing helmet = 48
Percentage which are not wearing the helmets
= [tex]\frac{48}{900}\times 100 = 5.3 %[/tex]%
I know i’m asking a lot of questions but help me please. Is this correct?
Answer:
Option A
Step-by-step explanation:
ok so firstly this is super duper easy! all you have to see first in these type of questions is the "sequence" or the "pattern". and you have to make a ittle equation with this, so the first picture has 1 square, secound one has 5, the third one has 9, and the fourth one has 13.
- so firstly see or find a specific sequence.
13 - 9 = 4
9 - 5 = 4
5 - 1 = 4
so we found out "4" is the main changing unit. Now lets make a short formula which will help us determine any number ahead of the picture.
so lets do 4x = number of squares, x= figure number
4(1) = 4 :: wrong, because the first figure has only one square
so, 4x - 3
4(1) - 3 = 1 :: correct! this euqation works!
Now, we need to find how many squared there are in figure 100, so ->
4(100) - 3 = 397 squares!
and now doing the question will be easier, because option A says 1 square in the centre and 99 sqaures on each side.
So-> 99 + 99 + 99 + 99 +1 = 397! boom!! got the answer!
