Use the figure to the right to find the value of PT. T is the midpoint of PQ.
PT = 5x +2 and TQ = 7x-6
PT=
(Simplify your answer.)
Answer:
22
Step-by-step explanation:
Given that T is the midpoint of line PQ, segments PT = 5x + 2, and TQ = 7x - 6 that are formed would be equidistant or congruent. PT = TQ.
Therefore:
[tex] 5x + 2 = 7x - 6 [/tex]
Let's find the value of x
Rearrange the equation, so that the terms having x would be on your left, while those without x would be on your right.
[tex] 5x - 7x = - 2 - 6 [/tex]
[tex] -2x = -8 [/tex]
Divide both sides by -2
[tex] x = 4 [/tex]
Plug in the value of x into the expression, 5x + 2, to find PT.
PT = 5(4) + 2 = 22.

M is the midpoint of ST. S(-8, 9) and M(-10, 14). Find the coordinates of the other endpoint, T.
Answer:
T = (-12, 19)
Step-by-step explanation:
We know that the definition of the midpoint is ...
M = (S + T)/2
Solving for T gives ...
T = 2M -S
T = 2(-10, 14) -(-8, 9) = (-20+8, 28-9)
T = (-12, 19)
Nina is training for a marathon. She can run 4 1/2 kilometers in 1/3 of an hour. At this pace, how many kilometers can Nina run in 1 hour
Answer:
13½ kilometers
Step-by-step explanation:
If Nina runs 4½ km in ⅓ of an hour, at this pace, the number of km she'd run in an hour can be calculated as follows.
Let x be the number of km to run in an hour.
4½km => ⅓ hr
x km => 1 hr
Cross multiply
[tex] 1*4\frac{1}{2} = \frac{1}{3}*x [/tex]
[tex] 4\frac{1}{2} = \frac{x}{3} [/tex]
Multiply both sides by 3
[tex] 4\frac{1}{2}*3 = \frac{x}{3}*3 [/tex]
[tex] \frac{9}{2}*3 = x [/tex]
[tex] \frac{27}{2} = x [/tex]
[tex] 13\frac{1}{2} = x [/tex]
x = number of km Nina runs in 1 hour = 13½ kilometers

urgio wants to buy gifts for 8 friends. he wants to gie the same gife to all his friends and he plans to have all the gifts wrapped in additional charge for 1.50 dollars each. if sergio spends at least 70 dollars he will recieve free shipping on his order. write and inequality to determine how much sergio needs to spend on each gift to order to receive free shipping
[tex]7.25 \leqslant x[/tex]
Step-by-step explanation:
you do 1.5×8 to see how much shipping cost
you get 12 then subtract 12 from 70 and you get 58, then you do 58÷8 and you get $7.25
so he needs to spend $7.25 or more on each friend. (im pretty sure)
The amount urgio needs to spend on each gift in order to receive free shipping is 7.25.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Given that urgio wants to buy gifts for 8 friends. he wants to gie the same gife to all his friends and he plans to have all the gifts wrapped in additional charge for 1.50 dollars each.
Let the cost of each gift = c
urgio is buying gifts for 8 friends = 8 gifts
Hence, the Inequality equation is written as:
(c + $1.50)× 8 ≥ $70
8c + 12 ≥ 70
8c ≥70 - 12
c ≥ 58/8
c≥ 7.25
Therefore, the amount urgio needs to spend on each gift in order to receive free shipping is 7.25

Find an equation of the line parallel to y=x+3 and that passes through the point (1 -5)
Answer:
y=x-6
Step-by-step explanation:
Y=x+3 according to this equation, the gradient is 1 comparing to y=mx+c. so m is the gradient. so from the equation, the coefficient of x is 1. since the line is parallel so it means the new equation has the same gradient m.
y=x+c but it passes through 1,-5...when x= 1, y=-5 from here , we Can find the new intercept c. -5=1+c. so c=-5-1=-6
the new equation y=x-6

49, 35 and 32 are composite and the rest are orime numbers
Answer:
[tex] \boxed{ \bold{ \huge{\boxed {\sf{49 \: , \: 35 \: , \: 32}}}}}[/tex]
Step-by-step explanation:
Composite numbers are whole numbers that can be divided by numbers other than itself and 1.
Among 49 , 35 , 32 , 41 and 47,
: 49 , 35 and 32 are composite numbers.
49 is a composite number as it comes in the multiplication table of 1 , 7 and 49 . So, this means it comes in the table of more than 2 numbers. 35 is a composite number as it comes in the multiplication table of 1 , 5 , 7 and 35.32 is a composite number as it comes in the multiplication table of 1 , 2 , 4 and 16. 41 is not a composite but a prime number as it comes in the multiplication table of only 1 and 41 [ 1 and itself ] 47 is not a composite but a prime number as it comes in the multiplication table of only 1 and 47 [ 1 and itself ]Hope I helped!

If Marcus drives no faster than 65 miles per hour, what is the domain that includes all possible average speeds using interval notation?
A [0.65)
B. [65,00)
C. (0.65)
D. (65.00)
Answer:
{0, 65]
Step-by-step explanation:
A function shows the relationship between two variables (an independent and dependent variable). The independent variable is not dependent on other variables, it is considered as the input while the dependent variable is dependent on other variables and considered as output.
The speed of Marcus must not be faster than 65 mph, hence speed ≤ 65 mph. This means that Marcus can drive with speed ranging from 0 mph to 65 mph, hence 0 ≤ speed ≤ 65 mph. This is represented using the interval notation:

7/60=5/24w+11/12 please help!!!!
Answer:
Step-by-step explanation:
w = -3 and 21/25
The value of w in 7/60=5/24w+11/12 is 6/5.
Given,
7/60 = 5/24 w + 11/12
We need to solve for w.
How do we solve an equation?It depends on the type of equation given.
We need to keep the variable that we are solving for in one side and simplify the other terms.
Find the value of w.
We have,
7/60 = 5/24 w + 11/12
Subtract 11/12 on both sides.
7/60 - 11/12 = 5/24 w + 11/12 - 11/12
7/6 - 11/12 = 5/24 w
Simplify the left-hand side into a fraction.
(14 - 11 ) / 12 = 5 / 24 w
3 / 12 = 5 / 24 w
Multiply 24 / 5 on both sides.
24/5 x 3/12 = 24/5 x 5/24 w
6 / 5 = w
w = 6 / 5
Thus the value of w in 7/60=5/24w+11/12 is 6/5.

A truck parked on the street is 56 m from the base of the apartment building on the right. The angle of elevation from the truck to the top of the building is 40°. The parked truck is 49 m from the base of the apartment building on the left. The angle of elevation from the truck to the top of that building is 50°. Which building is taller?
Answer:
Building to the left is taller.
Step-by-step explanation:
Kindly refer to the attached diagram for the given dimensions.
[tex]\triangle ABR, \triangle PQR[/tex]
AB and PQ be the two buildings.
The car be parked at point R.
[tex]\angle ARB = 50^\circ\ and \\\angle PRQ = 40^\circ[/tex]
Distance of R from building bases:
BR = 49 m
QR = 56 m
Let us use tangent in [tex]\triangle PQR:[/tex]
[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]
[tex]tan40 = \dfrac{h_1}{56}\\\Rightarrow h_1 = 56 \times 0.839 \\\Rightarrow h_1 \approx 47\ m[/tex]
Let us use tangent in [tex]\triangle PQR:[/tex]
[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]
[tex]tan50 = \dfrac{h_2}{49}\\\Rightarrow h_2 = 49 \times 1.19 \\\Rightarrow h_2 \approx 58.4\ m[/tex]
So, building to the left is taller.

So we have the function:

And we want to find:
[tex]g(s+1)[/tex]
So, substitute y for (s+1):
[tex]g(y)=7-6y\\g(s+1)=7-6(s+1)\\[/tex]
Distribute:
[tex]g(s+1)=7-6s-6[/tex]
Subtract:
[tex]g(s+1)=-6s+1[/tex]
5)
So we have the function:
[tex]h(t)=t^2-2t[/tex]
And we want to find:
[tex]h(x-3)[/tex]
So, substitute t for (x-3):
[tex]h(t)=t^2-2t\\h(x-3)=(x-3)^2-2(x-3)[/tex]
Square and distribute:
[tex]h(x-3)=(x^2-6x+9)+(-2x+6)[/tex]
Combine like terms:
[tex]h(x-3)=(x^2)+(-6x-2x)+(9+6)[/tex]

A wildlife habitat houses 41 animals. There are three more reptiles than mammals in the habitat. There are seven fewer amphibians than mammals in the habitat. How many amphibians are there in the habitat?
Answer: 8
Step-by-step explanation:
Let mammals be represented by y
There are three more reptiles than mammals in the habitat. Therefore, Reptiles = y + 3
There are seven fewer amphibians than mammals in the habitat. Therefore, amphibian = y - 7
y + y + 3 + y - 7 = 41
3y - 4 = 41
3y = 41 + 4
3y = 45
y = 45/3
y = 15
Since amphibian = y - 7
= 15 - 7
= 8
There are 8 amphibians

En un supermercado tienen dos contadores eléctricos de flujo de personas 1 registra de 3 en 3 y el otro de 5 en 5 en el momento que ambos se detienen unos señala de 840 y el otro de 560 diga Cuál de los dos es el que marca de 3 en 3?
Answer:
El contador que señala 840 registra de 3 en 3.
Step-by-step explanation:
Existe un truco para determinar si un número es múltiplo de 3, si la suma de sus dígitos es 3 o uno de sus múltiplos, entonces el número es un múltiplo de 3. En consecuencia, corresponde al contador eléctrico que registra de 3 en 3 y el otro contador eléctrico sería el que registra de 5 en 5.
Primer contador: 840
[tex]x = 8+4+0[/tex]
[tex]x = 12[/tex]
12 es un múltiplo de 3, por tanto, este contador es el que registra de 3 en 3.
Segundo contador: 560
[tex]x = 5+6+0[/tex]
[tex]x = 11[/tex]
11 no es un múltiplo de 3. Asimismo, todo número que sea múltiplo de 5 termina en 5 o 0, entonces este contador es el que registra de 5 en 5.
El contador que señala 840 registra de 3 en 3.
