Step-by-step explanation:
write the sentence as an inequality
a number m is more than -7 2/3 or at most -10
See attachment for math work and answer.
The given statement in the form of inequality can be written as,[tex]-7 \dfrac{2}{3} \leq m \leq -10[/tex]
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that,
A number m is more than -7(2/3) or at most -10
From the given data it is observed that the value of the number lies between -7(2/3) and -10.\
The given data can be written in the terms of inequality as,
[tex]-7 \dfrac{2}{3} \leq m \leq -10[/tex]
Thus, the given statement in the form of inequality can be written as,[tex]-7 \dfrac{2}{3} \leq m \leq -10[/tex]

Review the proof of the identity cos(π − A) = −cosA.
cos(π − A)
Step 1: = cosπcosA − sinAsinπ
Step 2: = (−1)(cosA) + (sinA)(0)
Step 3: = −1cosA + (sinA)(0)
Step 4: = −cosA + 0
Step 5: = −cosA
At which step was an error made?
step 1
step 2
step 3
step 4
Answer:
error in step 1
Step-by-step explanation:
well where is does the step not make sense?
remember cos(pi) = -1 and sin(pi)=0
that means step 1 is strange... it didn't distribute properly
it should have been:
cos(pi) - cos(A)
hope that helps! ^-^
The error is made at step 1). The correct trigonometric identity is cos(π - A) = cosπcosA + sinπsinA.
What are trigonometric identities?Trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined.
cos(π - A) = cosπcosA + sinπsinA

steps to solve 6-3y=-6
Answer:
y = -4
Step-by-step explanation:
6 - 3y = 6
now were going to get the variable and the numbers on different sides
6 - 3y - 6 = - 3y
6 + 6 = 12
now divide each side by -3
-3y / -3 = y
12 / -3 = -4

Answer: B
Step-by-step explanation:
if m2 = 125, m12= 37 and m18 = 102, find the measure of each angle
Answer/Step-by-step explanation:
Given:
m<2 = 125°
m<12 = 37°
m<18 = 102°
a. m<1 + m<2 = 180° (linear pair)
m<1 + 125° = 180° (substitution)
m<1 = 180° - 125°
m<1 = 55°
b. m<3 = m<18 (alternate exterior angles)
m<3 = 102° (substitution)
c. m<4 + m<3 = 180° (linear pair)
m<4 + 102° = 180° (substitution)
m<4 = 180° - 102°
m<4 = 78°
d. m<5 = m<2 (vertical angles)
m<5 = 125° (substitution)
e. m<6 = m<1 (vertical angles)
m<6 = 55° (substitution)
f. m<7 = m<12 (alternate angles)
m<7 = 37° (substitution)
g. m<8 + m<12 + m<13 = 180° (sum of triangle)
m<12 = 37° (given)
m<13 = m<18 = 102° (vertical angles)
m<8 + 37° + 102° = 180° (substitution)
m<8 + 139° = 180°
m<8 = 180° - 139°
m<8 = 41°
h. m<9 = m<18 (corresponding angles)
m<19 = 102° (substitution)
i. m<10 = m<6 (alternate interior angles)
m<10 = 55°
j. m<11 + m<6 + m<7 = 180° (sum of triangle)
m<11 + 55° + 37° = 180° (substitution)
m<11 + 92° = 180°
m<11 = 180° - 92°
m<11 = 88°
k. m<13 = m<18 (vertical angles)
m<13 = 102°
l. m<14 = m<4 (corresponding angles)
m<14 = 78°
m. m<15 = m<5 (corresponding angles)
m<15 = 125°
n. m<16 = m<6 (corresponding angles)
m<16 = 55°
o. m<17 = m<14 (vertical angles)
m<17 = 78°

there are 4 swimmers. amy swam 2 more laps than sean. katie swam twice as many laps as sean. tom swam 4 more laps than katie. all together the 4 swimmers swam a total of 78 laps. how many laps did sean swim?
Answer:
Sean swam 12 laps.
Step-by-step explanation:
Let S represent Sean
Let S+2 represent Amy
Let 2S represent Katie
Let 2S + 4 represent Tom
Now add together and set it equal to 78
S + S+2 + 2S + 2S+4 = 78
6S + 6= 78
6S=72
S=12
Chloe went on vacation with her family and they decided to swim with the dolphins there's a flat fee of $75 for the family to rent wet suits additionally a cost an extra $189.99 per person to swim with the dolphins the families total cost was $1024.99 how many family members went swimming with the dolphins
Answer:
5 family members went swimming with the dolphins.
Step-by-step explanation:
From the information given, you can say that the total cost for the family to swim with dolphins is equal to the flat fee for the family to rent wet suits plus the extra cost per person for the number of family members:
1024.99=75+189.99x, where x is the number of family members
Now, you can solve for x:
1024.99-75=189.99x
949.99=189.99x
x=949.99/189.99
x=5
According to this, the answer is that 5 family members went swimming with the dolphins.

A summer camp has 720 ft of float line with which to rope off three adjacent rectangular areas of a lake for swimming lessons, one for each of three levels of swimming ability. A beach forms one side of the swimming areas. Suppose that the width of each area is x feet. Answer parts a) through c).
Step-by-step explanation:
Kindly find attached a detailed image to better understand the solution to this problem.
given that the total length of the line is 720ft
and also the line is divided into three sections
This means that the line will also be divided into three parts
720/3= 240feet so that a section will have two sides that are 240ft since the section forms a rectangular shape.
now for the other two sides
the total length of the rope is = one length size of the rectangle+ 4 width size of the rectangle
one width size of the rope is x
then 4 width size is 4x
720=length of rectangle +4x
length of rectangle= 720-4x
area of a rectangle is =length *width
area of rectangle is = (720-4x)*x
Hence the function A= (720-4x)x can be used to solve for the area of the rectangle.
