In ARST, the measure of ZT=90°, the measure of ZR=39°, and TR = 55 feet.
Find the length of ST to the nearest tenth of a foot.
Answer:
ST = 44.5 feet
Step-by-step explanation:
sing SOH CAH TOA to solve the problem;
Given
m<T = 90
m<R = 39 degrees
TR = 55feet
Required
ST = opposite to m<R
TR is the adjacent
tan theta = opp/adj
tan m<R = ST/TR
tan 39 = ST/55
ST = 55tan39
ST = 55*0.8098
ST = 44.5 feet

Answer:
92
Step-by-step explanation:
92+88= 180 all suplementtary angles =180
Answer:
92
Step-by-step explanation:
∠X And ∠Y are supplementary.
• Measure of ∠Y = 88°.
• We have to find measure of ∠X.
• Sum of 2 supplementary angles is always = 180°.
X+Y=180
X+88=180
X=180-88
X=92
We described numbers in this lesson using both powers of 10 and using standard decimal value. For example, the speed of light through ice can be written as a multiple of a power of 10, such as (2.3)⋅108 meters per second, or as a value, such as 230,000,000 meters per second. Use the number line to answer questions about points A and B.
Describe point B as:
a. A multiple of a power of 10
Describe point A as:
a. A multiple of a power of 10
Answer:
B = 2×10⁸
A = 3×10⁸
Step-by-step explanation:
Box A has 2 rectangles with base 10 inches and height 4 inches. It has 2 rectangles with base 10 inches and height 3 inches. It has 2 rectangles with base 3 inches and height 4 inches.

Answer:
You need to give the answer in ratio
Its really easy
Last year you mowed grass and shoveled snow for 22 households.
You earned $150 per household mowing for the entire season and $225 per household shoveling the entire season.
If you earned a total of $3900 last year, how many households did you mow and shovel for last year?
Step-by-step explanation:
Let x be the number of households you mowed grass.
Let y be the number of households you shoveled snow.
From there, we know,
[tex]x + y = 22[/tex]
as equation 1.
next we also know,
[tex]150x + 225y = 3900[/tex]
as equation 2.
From here we know we can solve using simultaneous equations.
rearranging equation 1 with y the subject,
[tex]y = 22 - x[/tex]
Substitute this equation into equation 2.
[tex]150x + 225(22 - x) = 3900 \\ 150x + 4950 - 225x = 3900 \\ - 75x + 4950 = 3900 \\ - 75x = 3900 - 4950 \\ - 75x = - 1050 \\ x = - 1050 \div - 75 \\ = 14[/tex]
now substitute x = 14 into equation 1.
[tex]14 + y = 22 \\ y = 22 - 14 \\ = 8[/tex]
Therefore, you have mowed grass for 14 households and shovelled snow for 8 households.
What is the minimum y-value after which the exponential function will always be greater than the linear function? y = 1 y = 3 y = 4 y = 5
Answer:
y = 4.
Step-by-step explanation:
I suppose that this question relates to the image that can be seen below.
In the image, the green line represents the exponential function and the blue line represents the linear function.
The y-value after which the exponential function will always be greater than the linear function is the y-value where bot graphs intersect, such that after that point, the blue line starts increasing fast, and is always above the green line.
In this case, this point is the second intersection, and we can see that this intersection happens in the point (2, 4)
Remember that the usual notation for points is (x, y).
Then the y-value after which the exponential function will always be greater than the linear function is y = 4.

Figure FGHJ is shown below.
Figure F G H J has 4 sides. Sides F J and G H are congruent and parallel, and sides G F and H J are congruent and parallel. Angles G and J are 130 degrees.
Which names accurately describe figure FGHJ? Select two options.
parallelogram
quadrilateral
rectangle
rhombus
trapezoid
Answer:
1. 14m, 11, 18m
2. 132 (rounded from 131.946)
3. Quadrilateral (duh it has 4 sides) and a rhombus?
Step-by-step explanation:
1 a unique triangle is a triangle with side lengths that are ALMOST exactly like a triangle. I used the pyragothem theory (a^2 + b^2 equals c^2) and this one was soo close to 18 (17.8)
2 the equation for the circumference of a circle is C=dpi. the radius is half of the diameter so 21 time 2 is 42 then multi[ply by pi.
3 is definitely already a quadrilateral (all of them have 4 sides) and the only shade i can think of that can have a 130 degrees for 2 angles would be a longgg rhombus ( or diamond)
