Paso uno:
datos dados
el costo de un metro de cinta tricolor = $ 15.5.
se nos dice que un lazo necesitará 3,5 m de cinta, ya que tu madre hizo dos lazos, usó un total de 3,5 * 2 = 7 m de cinta
Segundo paso:
ahora calcularemos el dinero que gastó su madre.
si 1 m le costará $ 15.5
entonces 7 millones le costarán $ x
Cruz multiplicar tenemos
x = 15,5 * 7
x = $ 108.5
Esto significa que tu madre gastará $ 108.5 para hacerte los dos moños.
Queremos saber cuanto pagó mamá dado que conocemos cuantos metros de listón utilizo y cuanto cuesta el metro. Veremos que mamá pagó $54.25 por el listón.
Sabemos que cada metro del listón cuesta $15.50.
Tambien sabemos que mamá utiliza 3.5 metros de este listón, entonces el precio será 3.5 veces el precio del metro de liston, que es $15.50, esto se calcula como:
3.5*$15.50 = $54.25
Es decir, mamá pagó $54.25

Jennifer walks 9 blocks south and 5 blocks west. Approximately how many blocks is she from
home if she were to take a direct path?
Answer:
10.3 (Rounded up)
Step-by-step explanation:
Pythagorean's theorem.
a^2 + b^2 = c^2
You're finding c^2, which is the direct path she would take to get back home. 9^2 + 5^2 is 81 + 25 = 106. Square root of 106 is 10.3 rounded up.

Meteorology A Weather forecaster uses a barometer to measure air pressure and make weather predictions. Suppose a standard mercury barometer reads 29.8 in. The mercury rises 0.02 in. And then false 0.09 in . The mercury falls again 0.18 in. Before rising 0.07 in. What does the word "rise" suggest? What does the word "fall" suggest?
Answer:
rise : atmospheric pressure increases
fall : atmospheric pressure decreases
Step-by-step explanation:
In the context, it is given that a weather forecaster takes the help of the barometer to check the air pressure and predicts the weather. The column of mercury level in the barometer shows a rise or fall in the glass tube as the weight of the atmosphere falling on the mercury surface changes.
Here it is given that the mercury rises for 0.02 in, then it falls 0.09 in, it then rises by 0.07 in and then again falls by 0.18 in. The word "rise" here shows that the weight of the atmosphere is more. In other words, increase in atmospheric pressure increases the level of mercury in the glass tube and the decrease in or "fall" in the mercury level shows the drop in atmospheric pressure.
Given congruent triangles ΔRST ΔLMN where MN = 33, LN = 54, and RT = 4x+6 . Find the value of x
Answer:
x=12
Step-by-step explanation:
We know that both triangles are congruent meaning corresponding parts are equal. We know that line LN=54 and that RT=LN meaning that RT also equals 54. With that information we can simply subtract 6 from 54 to get 48 then divide by 4 to get 12. Hope this helps!
The breadth and length of a rectangle are in the ratio 4:5 and its area is
32 sqm. What are the length and breadth?
Answer:
[tex]length=(\sqrt{40} )m,breadth=\frac{4\sqrt{40} }{5} m[/tex]
Step-by-step explanation:
So the ratio 4:5 relates the length and breadthNow the length is always longer that the breadth so 5 represents the length and 4 the breadthA ratio can be written as a fraction so [tex]4:5=\frac{4}{5}[/tex] Let [tex]l[/tex] mean length and [tex]b[/tex] breadth, so the ratio [tex]b:l=4:5,so,b:l=\frac{b}{l}=\frac{4}{5}[/tex] So if [tex]\frac{b}{l}=\frac{4}{5}[/tex] then multiply both sides by [tex]l[/tex] and you get [tex]b=\frac{4}{5} l[/tex] Now the equation for area is [tex]area=length*breadth[/tex] or [tex]A=l*b[/tex]Since our breadth [tex]b[/tex] equals [tex]\frac{4}{5} l[/tex] then we substitute for the breadthSo [tex]A=l*(\frac{4}{5}*l)=\frac{4}{5}*l*l=\frac{4}{5} l^2[/tex] so [tex]A=\frac{4l^{2}}{5}[/tex] We know the Area is [tex]32m^2[/tex] so [tex]32m^2=\frac{4l^{2}}{5}[/tex] so we simplify [tex]5*(32m^2)=5*(\frac{4*l^{2}}{5})\\ 160m^2=4*l^2\\ \frac{160m^{2}}{4}=\frac{4*l^{2}}{4} \\ 40m^2=l^2\\ l^2=40m^2\\ \sqrt{l^{2}} =\sqrt{40m^{2}} \\ l=(\sqrt{40})m[/tex] Now we find the breadth, since [tex]b=\frac{4}{5}*l \\ b=\frac{4}{5}*(\sqrt{40} )m\\ b=\frac{4\sqrt{40} }{5} m[/tex]Which function rule does the graph represent?

As an estimation we are told 5 miles is 8 km.
Convert 96 km to miles.
Answer:
90km is equal 56.25 miles
Answer:
Around 60 miles.
Step-by-step explanation:
First I found that 1 mile was equivalent to around 1.6 km.
8/5=1.6
To find how many miles were equivalent to 96 km I did
96/1.6=60.
60 miles are equivalent to 96 km.
(If you used a km to miles converter it would say exactly 59.6516)

The value of the given number 1 x 10¹⁰⁰ by applying the logarithms is equal to 100.
To find the number represented by 1 x 10¹⁰⁰ using logarithms, we can use the base-10 logarithm function.
The logarithm (base-10) of a number x is denoted as log(x) and represents the power to which 10 must be raised to get the number x.
Here, we have 1 x 10¹⁰⁰, and we want to find the value of x.
Using the logarithmic expression:
log(1 x 10¹⁰⁰) = log(1) + log(10¹⁰⁰)
The logarithm of 1 (log(1)) is equal to 0, so the expression simplifies to:
log(1 x 10¹⁰⁰) = 0 + log(10¹⁰⁰)
Now, using the property of logarithms, log(aᵇ) = b × log(a):
log(1 x 10¹⁰⁰) = 0 + 100 × log(10)
The logarithm of 10 (log(10)) is equal to 1, so:
log(1 x 10¹⁰⁰) = 0 + 100 × 1
Finally:
log(1 x 10¹⁰⁰) = 100
Therefore, the value of the number 1 x 10¹⁰⁰ using logarithms is 100.

A flagpole is 15 feet tall. Its shadow is 20 feet long. How far is it from the top of the flagpole to the end of the shadow?
Answer:
5 feet.
Step-by-step explanation:
The angle of the height and length go down to 5 feet diagonally.
Answer:
25ft
Step-by-step explanation:
To find the length of the top of the flagpole to the end of the shadow, you have to use the Pythagorean theorem a² + b² =c²
15² + 20² = x²
225 + 400 = x²
625 = x²
√625 = √x²
x = 25
Please help ASAP! Is angle BAD less than, greater than, or equal to 90 degrees? Explain why. What about angle BCD?
9514 1404 393
Answer:
∠BAD < 90°∠BCD > 90°Step-by-step explanation:
Angle BAD is an inscribed angle, so is half the measure of the arc it intercepts. Chord BD is on the far side of the circle's center from vertex A, so the arc intercepted by angle BAD is less than 180°. This means angle BAD is less than 180°/2 = 90°.
∠BAD < 90°
__
Angles BAD and BCD are supplementary, so if one is less than 90°, the other must be greater than 90°.
∠BCD > 90°
Answer: I would say that it is equal to.
Step-by-step explanation: The angle in the bottom corner of the triangle is a right angle if you measure it with a protractor.
A picture frame 4 inches wide by 6.5 inches high has a 3 inch by 5 inch photograph place in the center. What is the area of the frame?
Area = l × w
= 6.5 × 4
= 26 feet2
Answer:
[tex]A_f=11~inches[/tex]
Step-by-step explanation:
Area of a Rectangle
A rectangle of width W and height H has an area of:
A = W.H
We have one rectangle inside another. The first rectangle corresponds to the frame and its contents. The second rectangle corresponds to the photograph.
The area of the frame without its contents is the difference between both areas:
[tex]A_f = A_e-A_i[/tex]
Where Ae is the external area of the frame, and Ai is the internal frame of the photograph.
The frame has W=4 inches and L=6.5 inches, thus:
[tex]A_e=4~inches*6.5~inches[/tex]
[tex]A_e=26~inches[/tex]
The photograph has W=3 inches and L=5 inches, thus:
[tex]A_i=3~inches*5~inches[/tex]
[tex]A_i=15~inches[/tex]
The area of the frame is:
[tex]A_f = 26 - 15 = 11~inches[/tex]
[tex]\mathbf{A_f=11~inches}[/tex]
