Answer:
3.6h - 3.1d + 13
Step-by-step explanation:
Combine like terms. Like terms have same variables.
Like terms : (i) 6h and (-2.4h) (ii) -8.1d and 5d
6h + (-8.1d) - 13 + 5d - 2.4h = 6h - 2.4h + (-8.1d) + 5d - 13
= (6 - 2.4)h + (-8.1 + 5)d - 13
= 3.6h - 3.1d + 13
Find the value of x. Round to the
nearest tenth.

x =
Answer:
x ≈ 10.9
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{x}[/tex] ( multiply both sides by x )
x × sin40° = 7 ( divide both sides by sin40° )
x = [tex]\frac{7}{sin40}[/tex] ≈ 10.9 ( to the nearest tenth )
Give that each figure shown below is a trapezoid. Find the missing values.
Answer:
EF=22
C=70°
B=110°
Step-by-step explanation:
Trapezoids have to have a total of 360° and there are complementary angles.
the straight line L, has equation y=3x-4 The straight line 1, in perpendicular to L, and passes through the point (9.5) Find an equation of line L
Given:
The equation of given line is
[tex]y=3x-4[/tex]
A line is perpendicular to the given line and passes through the point (9,5).
To find:
The equation of the perpendicular line.
Solution:
We have,
[tex]y=3x-4[/tex]
On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get
[tex]m=3[/tex]
It means, the slope of the given line is 3.
The product of slopes of two perpendicular lines is -1.
[tex]m\times m_1=-1[/tex]
[tex]3\times m_1=-1[/tex]
[tex]m_1=-\dfrac{1}{3}[/tex]
Point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope.
The slope of perpendicular line is [tex]-\dfrac{1}{3}[/tex] and it passes through the point (9,5). So the equation of the line is
[tex]y-5=-\dfrac{1}{3}(x-9)[/tex]
[tex]y-5=-\dfrac{1}{3}(x)-\dfrac{1}{3}(-9)[/tex]
[tex]y-5=-\dfrac{1}{3}x+3[/tex]
Adding 5 on both sides, we get
[tex]y-5+5=-\dfrac{1}{3}x+3+5[/tex]
[tex]y=-\dfrac{1}{3}x+8[/tex]
Therefore, the equation of required line is [tex]y=-\dfrac{1}{3}x+8[/tex].

The price of an oven was increased by 20% to £156.
What was the price before the increase?
Answer:
Step-by-step explanation:
Before the increase it was 100%
So 20+100=120
156/120*100=130$
Don’t do it like 20/100 *156 and then minus it from 156 because you will get a wrong answer
(This was answered by another person on a another question.)
Answer:
130
Step-by-step explanation:
x * 1.2 = 156
x = 156/1.2
x = 130

Danielle is keeping track of the amount of money in her lunch account. She starts with $36 in the account and uses 3 dollars every day for lunch. Which equation below could she use to track the amount of money in her account if M=the money in her account and d=the number of days?
M = 36 + 3d
M = - 3d + 36
M = - 36 + 3d
M = 3 + 36d
Answer:
M=-3d+36

Find the missing angle measure.
Need help please!!!
Answer:
This shape is a hexagon. Angles in a hexagon add to 720 degrees.
2(y) + 4(2y-20) = 720
2y + 8y-80 = 720
10y-80=720
10y=800
y=80

What is “F” in this triangle problem thingy
Answer:
f=43
Step-by-step explanation:
Hey There!
So if you didn't know the exterior angle (aka f) is equal to the sum of the opposite interior angles
so essentially what i am saying is that
19+24=f
19+24=43
therefore
f=43
hope this helps :)
if you have anymore questions just let me know

Viola drives 2 kilometers up a hill that makes an angle of 4 degrees with the horizontal. To the nearest tenth of a kilometer, what horizontal distance has she covered
Answer:
2.0 km
Step-by-step explanation:
From the diagram attached,
cosθ = adjacent/Hypotenus
cos4° = x/2
make x the subject of the equation
x = 2cos4°
x = 2(0.998)
x = 1.995
x = 2.0 km. (to the nearest tenth)
Hence the horizontal distance is 2.0 km

Help pls 10 points
A x=56
B x=156
C x=166
D x=66
D: x=66
Step-by-step explanation:
As we know the angle is 90 degree.Then x+24 degree is equal to 90 degree as whole part axiom. If we subtract 24 from 90 we get 66

A sequence can be generated by using an = 4a(n - 1)) where a= 6 and n is a whole
number greater than 1. What are the first four terms in the sequence?
Given:
The sequence can be generated by
[tex]a_n=4a_{(n - 1)}[/tex]
Where [tex]a_1= 6[/tex] and [tex]n[/tex] is a whole number greater than 1.
To find:
The first four terms of the given sequence.
Solution:
We have,
[tex]a_n=4a_{(n - 1)}[/tex] ...(i)
It is given that [tex]a_1= 6[/tex]. So, for [tex]n=2[/tex], we get
[tex]a_2=4a_{(2 - 1)}[/tex]
[tex]a_2=4a_1[/tex]
[tex]a_2=4(6)[/tex]
[tex]a_2=24[/tex]
Putting [tex]n=3[/tex] in (i), we get
[tex]a_3=4a_{(3- 1)}[/tex]
[tex]a_3=4a_2[/tex]
[tex]a_3=4(24)[/tex]
[tex]a_3=96[/tex]
Putting [tex]n=4[/tex] in (i), we get
[tex]a_4=4a_{(4- 1)}[/tex]
[tex]a_4=4a_3[/tex]
[tex]a_4=4(96)[/tex]
[tex]a_4=384[/tex]
The first four terms of the given sequence are 6, 24, 96,384.
Therefore, the correct option is C.

You deposit $300 in a savings account. The account earns 2% simple interest per year.
a. What is the interest earned after 10 years?
The interest earned is $ after 10 years.
b. What is the balance after 10 years?
The balance is $ after 10 years.
Answer:
Answer:
a. ----> $10
b. ----> $110
Step-by-step explanation:
Step-by-step explanation:
principle ( p ) = $100
time ( t ) = 10 years
rate ( r ) = 11%
simple interest = (p × r × t)÷ 100
= ( $100 × 11 × 10 )÷ 100
= 11000 ÷ 100
= $110
interest = simple interest - principle
interest = $110 - $100
= $10
If
x + 2y = 1
X– 2y = 13
then y =
Answer:
y = -3
Step-by-step explanation:
x + 2y = 1 then x = 1 - 2y
x– 2y = 13
substitute for x:
1 - 2y - 2y = 13
simplify:
-4y = 12
y = -3
x = 7
