The height of the mast on the bridge is 148 feet. Using the conversion 1 foot=30cm calculate the height of the mast in metres
Any help would be very useful, thank you
Answer:
44.4 meters
Step-by-step explanation:
Using 1 foot = 30 cm
convert 148 feet to centimeters by multiplying.
148ft × 30cm/1ft
= 148 × 30
= 4440 cm
Then convert cm to meters by dividing by 100.
1 meter = 100cm
4440cm × 1m/100cm
= 4440/100
= 44.4m
148 feet is 44.4m

© Decrease 20g by 25%
g.
Answer:
15g
Step-by-step explanation:
Method A: Calculate the percent first
If you decrease an amount by 25%, you end up with 75% of the amount.
75% of 20g = 0.75 × 20g = 15g
Method B: Calculate the decrease first
We start with 20g. To decrease 20g by 25%, we calculate 25% of 20g.
25% of 20g = 0.25 × 20g = 5g
The decrease amount is 5g.
Now we subtract 5g from 20g.
20g - 5g = 15g

Write an equation of the line in slope- intercept form
Answer:
[tex]d)\ y=x+5[/tex]
Step-by-step explanation:
Slope (m) form: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{5-2}{0-(-3)} \\\\m=\frac{3}{(0+3)} \\\\m=\frac{3}{3} \\\\m=1[/tex]
[tex]y=mx+b\\y=1x+b\\y=x+b[/tex]
(0, 5)
[tex]5=0+b\\5=b[/tex]
[tex]y=x+5[/tex]
Check your answer:
[tex]y=x+b\\5=0+5\\5=5[/tex]
This statement is true
Hope this helps!
Answer:
D. y=x+5
Step-by-step explanation:
Find the slope of the line. Remember to use equation: m=y2−y1/x2−x1
m= 5-(2)/0-(-3)
Simplify both numerator and denominator, then divide. You'll get m=1
Use the slope 1 and a given point (−3,2) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1).
y−(2)=1⋅(x−(−3))
Simplify the equation.
y−2=1⋅(x+3)
Solve for y by multiplying x+3 by 1.
y−2=x+3
Move everything that doesnt contain y to the right by adding 2 to both sides of the equation
y=x+3+2
and then added 3 and 2.
y=x+5

ΔLMN ~ ΔABC
Answer:
y = 6.3
Step-by-step explanation:
ΔLMN ~ ΔABC
The two triangles are similar which means the sides have the same proportions. To put it simply, one shape is just an enlargement of the other.
In this case, triangle ABC is an enlargement of triangle LMN so we can work out a scale factor.
To work out the scale factor, we can do 10 ÷ 7 = 1.4285714... To find y, all we have to do is divide 9 by the scale factor to get 6.3.
Hope this helps!
Ratio remains same as triangles are similar

what would the factorization of g(x)=x^2+12x+20
Answer:
Step-by-step explanation:
Product = 20
Sum = 12
Factors = 2 , 10 {2*10 = 20 & 2+10 = 12}
x² +12x + 20 = x² + 2x + 10x + 20 {Split the middle terms using the factors}
= x( x + 2) + 10(x + 2)

Alex wants to pay off his credit card balance before he gets married. He decides to take the $2,300 out of his savings and apply it to his credit card debt of $5,390. The credit card has an APR of 16. 5%. What will Alex's minimum monthly credit card payment be in order to pay off his debt in 14 months? a. $109. 40 b. $190. 83 c. $244. 15 d. $572. 32.
Answer:
$244.51
Step-by-step explanation:
Credit card payment =$5390
After paying $2300 from savings account,
Remaining payment left = 5390-2300 = $3090
APR = 16.5% or 0.165
Time (t) = 14 months = 14/12 years
Using credit card payment calculator,
Monthly payment = $244.15
Hence, minimum monthly payment to be made to pay off the whole debt in 14 months = $244.15

Answer: 33 degrees
Step-by-step explanation:
Since J and K are midpoints, JK must be parallel to GH.
If the linese are parallel, then angle IHG would equal angle IKJ because they would be corresponding angles. We can now set up an equation.
-7x + 75 = -4x + 57
Combine like terms:
3x = 18
Divide both sides by 3:
x = 6
Therefore, -7x + 75 = -7*6 + 75 = -42 + 75 = 33
Jill has an old bike. her parents gave her 40$ to repair it new tires is 21$ she also wants to buy a bell 5$ and a basket 13$ how much will she have left
Answer:
1$
Step-by-step explanation:
Her total amount is 40$
She then buys the tires(tires = 21$) so she bought that subtract 21$ from 40$ 40$ - 21$=19$
She next wanted to buy a bell so she did the bell was 5$ so subtract 5$ from 19$ 19$-5$=14$ left
So remember she has 14$ left and she is buying a basket which is 13$ so her buying the basket is remaining her with 1$ because basket is 13$ and she has 14$ so what is 14$-13$ it is 1$ and there's your answer.
1$

23. 18.3y- 7.6 = 8.4y - 14.6
24. 4.1x - 1.3= 0.7x + 25.9
Answer:
y = -0.71
x = 8
Step-by-step explanation:
Bring variables on one side of the equation
18.3y - 8.4y = -14.6 + 7.6
4.1x - 0.7x = 25.9 + 1.3
Solve for the variable
9.9y = -7
y = -70/99
3.4x = 27.2
x = 8

How do you factor 12y^2-6y-90
Answer:
6(y - 3)(2y + 5)
Step-by-step explanation:
12y^2 - 6y - 90
Factorize
6(2y^2 - y - 15)
Split the term
6(2y^2 - 6y + 5y - 15)
Regroup terms
6((2y^2 - 6y) + (5y - 15))
Factorize
6((2y(y - 3) + 5( y - 3))
Factorize
6(y - 3)(2y + 5)
Answer:
[tex]6(y-3)(2y+5)[/tex]
Step-by-step explanation:
[tex]12y^2-6y-90[/tex]
First, factor out the common term of 6:
[tex]\implies 6(2y^2-y-15)[/tex]
To factor [tex](2y^2-y-15)[/tex]:
Multiply the coefficient of [tex]y^2[/tex] by the constant:
[tex]\implies 2 \times -15 = -30[/tex]
Now find factors of -30 that sum to the coefficient of [tex]-y[/tex], i.e. -1
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
So factors of -30 that sum of -1 are: -6 and 5
Rewrite the middle term of [tex](2y^2-y-15)[/tex] as [tex]-6y + 5y[/tex]:
[tex]\implies 2y^2-6y+5y-15[/tex]
Factor each pair of terms:
[tex]\implies 2y(y-3)+5(y-3)[/tex]
Factor out the constant term:
[tex]\implies (y-3)(2y+5)[/tex]
Therefore, the final factorization is:
[tex]\implies 6(y-3)(2y+5)[/tex]
A cylinder and its dimensions are shown in the diagram. Which measurement is closest to the lateral surface area of the cylinder in square inches? 1,597.9 in2 677.3 in2 555.7 in2 1111.4 in2
Answer:
555.7 in²
Step-by-step explanation:
Lateral surface area of a cylinder is the "side" surface area only. Lateral SA does not include the surface area of the 2 circular ends.
[tex]\textsf{lateral SA}=2\pi rh[/tex]
(where r is the radius and h is the height)
Given:
diameter = 8.8 in ⇒ radius = 4.4 inheight = 20.1 inSubstituting these values into the formula:
[tex]\implies \textsf{lateral SA}=2\pi \cdot 4.4 \cdot 20.1[/tex]
[tex]\implies \textsf{lateral SA}=555.7 \textsf{ in}^2 \textsf{ (nearest tenth)}[/tex]

Steve started an after-school homework club. The club starts with 6 members and 3 more students join each
week. Define variables and write an equation to model the number of students in the club.
Answer:
y: students in the clubx: weeks after it was formedmodel: y = 3x +6Step-by-step explanation:
We are told to model the number of students in the club. That is the dependent variable, so we will assign 'y' to that quantity. The number of students in the club is a function of the number of weeks since it was formed, so we can assign 'x' to that independent variable.
The initial value of y is 6, and it increases by 3x (that is, 3 students each week). The model of the number of homework club students can be ...
y = 3x +6

Find the x-intercept of the line 20x - 17y = 15.
Write your answer as an integer or as a simplified proper or improper fraction, not as an
ordered pair.
Step-by-step explanation:
the line is
20x - 17y = 15
I am not sure what your teacher uses as "standard form".
the works is split between "point-slope" and "slope-intercept" form as "standard".
I usually pick "slope-intercept" :
y = ax + b
with a being the slope and b being the y-intercept.
in any case, we can find the x-intercept without bringing the line equation to one of these forms.
because x-intercept simply means that y = 0.
and for y=0 the original equation is then
20x - 17×0 = 15
20x = 15
x = 15/20 = 3/4
Would using the commutative property of addition be a good strategy
for simplifying 35 +82 +65? Explain why or why not.
Answer:
Yes
Step-by-step explanation:
Without using the property, you would have to do 35+82+65 which is messy. 35+82=117+65=182 ugh
Using the property however, tells you that you can do 35+65+82 which is easier to solve! 35+65=100+82=182
