what is 7-5 divided by 1/2x2

Will give brainliest to the first to answer

Answer:

2

Step-by-step explanation:

add 16 to zero

4x2=16

Divide 4x by 2 and 16 by two

4x=8

divide 8 by 4

x=2

Answer:

x = ± 2

Step-by-step explanation:

Given

4x² - 16 = 0 ( add 16 to both sides )

4x² = 16 ( divide both sides by 4 )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

solutions are x = - 2, x = 2

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

ΔJKL consist of 3 angles: ∠mLJK, ∠mKLJ and ∠mJKL

We are given the measures of ∠mLJK and ∠mKLJ

In order to find ∠mJKH we must find the missing angle in the triangle

Remember that angles in a triangle add up to equal 180

If we are given two angles we can find the missing angle by subtracting the measures of the known angles from 180

so ∠mJKL = 180 - 37 - 69

180 - 37 - 69 = 74

Hence, ∠mJKL = 74°

Now to find ∠mJKH

Angles ∠K, ∠mJKH and ∠mJKL appear to be formed on a straight line

Angles formed on a straight line add up to equal to 180

So ∠K + ∠mJKH  + ∠mJKL = 180 ( note that this is the equation that will be used to solve for ∠mJKH )

∠K is a right angle, indicated by the little square.

Right angles have a measure of 90° so ∠K = 90

We have also calculated the measure of ∠mJKH = ( 74° )

That being said we plug in the given values into the equation created earlier and solve for ∠mJKH

We would have 90 + ∠mJKH + 74 = 180

Now we solve for ∠mJKH

step 1: combine like terms

90 + 74 = 164

now we have 164 + ∠mJKH = 180

step 2 subtract 164 from each side

180 - 164 = 16

164 - 164 cancels out

we're left with ∠mJKH = 16

Hence the answer is C

Step-by-step explanation:

Just move the number by the log above the equation

Answer:

The correct option is B: the surface area of the second box is 4 times larger.

Step-by-step explanation:

The surface area of the first box is given by:

[tex] SA_{1} = 2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1} [/tex]

Where:

l₁: is the length = 8 in

h₁: is the height = 15 in

w₁: is the width = 6 in

[tex] SA_{1} = 2*8*15 + 2*6*15 + 2*8*6 = 516 in^{2} [/tex]

The second box's dimensions are:

l₂ = 2*8 in = 16 in

h₂ = 2*15 in = 30 in

w₂ = 2*6 in = 12 in

Hence, the surface area of the second box is:

[tex]SA_{2} = 2*2l_{1}*2h_{1} + 2*2w_{1}*2h_{1} + 2*2l_{1}*2w_{1} = 4(2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1}) = 4*SA_{1} = 4*516 in^{2} = 2064 in^{2}[/tex]

Therefore, the correct option is B: the surface area of the second box is 4 times larger.

Step-by-step explanation:

Answer:600

Step-by-step explanation:

Hey there!

7/4 = 35/m

CROSS MULTIPLY BOTH of your NUMBERS

7(m) = 4(35)

7(m) = 7m

4(35) = 140

NEW EQUATION: 7m = 140

DIVIDE 7 to BOTH SIDES

7m/7 = 140/7

CANCEL out: 7/7 because that gives you 1

KEEP: 140/7 because that gives you the value of m

140/7 = m

Solve above and you have the answer of m

140/7 = 20

Therefore, the value of m = 20

Answer: m = 20

Good luck on your assignment and enjoy your day!

Answer:

x<7

Step-by-step explanation:

Answer: x=7, x<18, true

Step-by-step explanation: -10 becomes +10, then you add 10+18. 4x<28 is now the expressio. 28/4=7, x=7 and x or 7<28. This equation is true.

y would be where u put the 3x by the x4

Answer:

11. parallelogram, rectangle

12. parallelogram, rhombus

13. parallelogram, square

For parallelogram:

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

for rectangle:

A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon and hexagon), and 4-gon (in analogy to n-gons for arbitrary values of n).

for rhombus:

In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond.

for Square:

·There are four methods that you can use to prove that a quadrilateral is a square. In the last three of these methods, you first have to prove (or be given) that the quadrilateral is a rectangle, rhombus, or both:

·If a quadrilateral has four congruent sides and four right angles, then it’s a square (reverse of the square definition).

·If two consecutive sides of a rectangle are congruent, then it’s a square (neither the reverse of the definition nor the converse of a property).

·If a rhombus contains a right angle, then it’s a square (neither the reverse of the definition nor the converse of a property).

·If a quadrilateral is both a rectangle and a rhombus, then it’s a square (neither the reverse of the definition nor the converse of a property).

Answer:

a = length

b = height(width)

a=3b

2(a+b)=120

2(b+3b)=2(4b)=8b

8b=120

b=15

a=45

length is 45 feet

width is 15 feet

Step-by-step explanation:

Answer:

33.3333%

explaination

When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form. Now we can see that our fraction is 33.333333333333/100, which means that 25/75 as a percentage is 33.3333%

Answer:

answer: C. 5 out of 10

Step-by-step explanation:

Theoretical probability is what is expected to happen sense a coin has 2 sides theres a 1/2 chance at getting heads so 5 out of 10 is the theoretical probability because 5 is half of 10 hope this helps!

Answer:

7.85

Step-by-step explanation:

firstly convert the 45 deg into radians

which is 0.785398 rads multiply it by ten ..

using the formula s=r∅

Answer:

Correct Answer Is 7.85

Step-by-step explanation:

Since 45 degrees is 1/8th of a circle Then you would find the circumference divided by 8.

10= Radius Then Circumference= 62.83

(Divide Circumference by 8) = 7.85 (Answer)

Answer:

C

Step-by-step explanation:

Answer:

its C.

Step-by-step explanation:

Answer:

x = 17

y = 8

QPR = 35º

QRP = 60º

Step-by-step explanation:

2x + 1 = x + 18

Subtract x from both sides

x + 1 = 18

Subtract 1 from both sides

x = 17

QPR = 2x + 1

QPR = 2(17) + 1

QPR = 35º

-------------------------------

8y - 4 = 4y + 28

Subtract 4y from both sides

4y - 4 = 28

Add 4 to both sides

4y = 32

Divide both sides by 4

y = 8

QPR = 8y - 4

QRP = 8(8) - 4

QRP = 60º

Answer:

y= -1.328

Step-by-step explanation:

15= k*-18

15=k*-18 (divide both sides by -18)

It doesn't go in evenly so you are left with a negative decimal

k= -0.83

Now find y

y= -0.83(1.6)= -1.328
