give the value of x in these equivalent ratio
x:77 -7:11
Step-by-step explanation:
[tex]x: 77 = 7 : 11 \\x = \frac{77 \times 7}{11} = \\ = 49[/tex]
From the given equivalent ratio the value of x is the number 49.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
The given equivalent ratios are x:77=7:11
"Two or more ratios that reflect the same relation or comparison of numbers are known as equivalent ratios," according to the definition of the equivalent ratio. The idea of corresponding fractions is comparable. The term "proportion" also refers to the equivalence of two ratios.
Here, x/77 = 7/11
Multiply both the numerator and denominator of the ratio 7/11 by 7, we get 49/77
Now, x/77 = 49/77
So, x=49
Therefore, the value of x is 49.

Based on the slopes of the side of the quadrilateral. Is this shape a trapezoid?
the slopes of the sides do not matter. It's the fact that AD and BC are parallel and AB and DC are NOT parallel that determines it to be a trapezoid.
Answer:
Yes
Step-by-step explanation:
I believe it would be :) sorry if it's wrong I'm just a 8th grader

Aidan rides his motorcycle at an average speed of 20 meters/second for 500 seconds, how far did he ride?
Answer:
[tex]10000[/tex] meters
Step-by-step explanation:
The formula for finding distance is ([tex](speed)*(time)=(distance)[/tex]). Substitute in the given values and solve to find the distance,
[tex](20)*(500)=10000[/tex]
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.

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

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

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)

Which quantity makes the equation true?
x + 3x + _______ = 7x
Answer:
Step-by-step explanation:
C) 3X
Answer: C. 3x
Step-by-step explanation:
Since x and 3x both have x, you can add them together to get 4x (if there is x by itself, it really means that there is one of it, so it would be 1x.)
Then, you subtract 7x by 4x, which gives you the answer, 3x. You could also solving it by asking yourself: What number plus 4x equals 7x, which would give you 3x.
