Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 10}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ \frac{4}{x} = \frac{28}{70}} [/tex]
Do cross multiplication
[tex] \longrightarrow{ \sf{28x = 4 \times 70}}[/tex]
Multiply the numbers: 4 and 70
[tex] \longrightarrow{ \sf{28x = 280}}[/tex]
Divide both sides by 28
[tex] \longrightarrow{ \sf{ \frac{28x}{28} = \frac{280}{28}}} [/tex]
Calculate
[tex] \longrightarrow{ \sf{x = 10}}[/tex]

Charlie runs a screen printing company and is resetting a machine he uses to print triangular banners. He knows the amount of material he needs for the banner as well as the height of the triangle, but he needs to set the machine to a new measurement for the triangle’s base. To help Charlie determine the new measurement, rewrite the standard formula for the area of a triangle, A = bh, to solve for the base, b. Enter the correct answer in the box.
Answer:
b= 2a/h
Step-by-step explanation:
The new measurement can be obtained by the formula b = 2A/h the answer is b = 2A/h
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have:
Charlie runs a screen printing company and is resetting a machine he uses to print triangular banners.
Given:
A = bh/2
Make subject as b
2A = bh
b = 2A/h
Thus, the new measurement can be obtained by the formula b = 2A/h the answer is b = 2A/h

Determine if the statement below makes sense. Explain.
Four friends administered a bake sale table for a day. They made a total of $376.35 over the course of the day. Determined to give everyone an equal share of the money, each friend received $94.0875.
A. This statement makes sense. Dividing 376.35 by 4 results in 94.0875.
B. This statement does not make sense. Money values must be rounded to the nearest dollar. Each friend should receive $94.
C. This statement does not make sense. Money values must be rounded to the nearest cent. Each friend should receive $94.08.
D. This statement does not make sense. Dividing 376.35 by 4 results in 91.8375. Each friend should receive $91.8375 instead.
Answer:
c
Step-by-step explanation:
$376.35 / 4 does equal to $94.0875 but when it comes to money, it should be rounded to the nearest cent being $94 and .08 cents.

solve for k 4.5+1.5k=18−3k
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{k = 3}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{4.5 + 1.5k = 18 - 3k}[/tex]
Move 3k to left hand side and change it's sign
Similarly, move 4.5 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{1.5k + 3k = 18 - 4.5}}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{4.5k = 18 - 4.5}}[/tex]
Subtract 4.5 from 18
[tex] \longrightarrow{ \sf{4.5k = 13.5}}[/tex]
Divide both sides by 4.5
[tex] \longrightarrow{ \sf{ \frac{4.5k}{4.5} = \frac{13.5}{4.5} }}[/tex]
Calculate
[tex] \longrightarrow{ \sf{k = 3}}[/tex]
Hope I helped!
Best regards! :D
Answer:
k = 3
Step-by-step explanation:
Subtract 4.5 from both sides:
4.5 + 1.5k = 18 - 3k
-4.5 -4.5
1.5k = 13.5 -3k
Subtract -3k from both sides:
1.5k = 13.5 - 3k
+3k +3k
4.5k = 13.5
Now simplify:
4.5k = 13.5
k = 3

Calculate the size of angle AEF
Answer:
90 degrees
Step-by-step explanation:
Answer:
The angle of AEF is 90°.
Step-by-step explanation:
Given that DEF is an equilateral triangle so all angles are the same which is 60° and in a regular square, all angles are 90°. Next, we have to find ∠ADE :
∠EDF = 60° / ∠CDF = 180° / ∠CDA = 90°
∠ADE = 180° - ∠EDF∠CDA
∠ADE = 180° - 60° - 90°
∠ADE = 30°
Given that ADE is an isosceles triangle so ∠ADE and ∠AED have the same angles. Lastly, we have to find ∠AEF by adding ∠AED and ∠DEF together :
∠AED = 30° / ∠DEF = 60°
∠AEF = ∠AED + ∠DEF
∠AEF = 30° + 60°
∠AEF = 90°

2. the quantity of 2 plus or minus i square root 10 all over 3
3. the quantity of 2 plus or minus i square root 2 all over 3
4. 1 plus or minus i square root 2
Step-by-step explanation:
9x² + 6 = 12x
3x² + 2 = 4x
3x² − 4x + 2 = 0
Use quadratic formula.
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-4) ± √((-4)² − 4(3)(2)) ] / 2(3)
x = [ 4 ± √(16 − 24) ] / 6
x = [ 4 ± √(-8) ] / 6
x = (4 ± 2i√2) / 6
x = (2 ± i√2) / 3
On a 210-mile trip, Cameron drove at an average speed of 60 miles per hour for the first x hours. He then
completed the trip, driving at an average speed of 50 miles per hour for the remaining y hours. If x = 1,
what is the value of y?
y =
Answer:
[tex]y = 3[/tex]
Step-by-step explanation:
Given
Trip = 250 miles
Speed for first x hours = 60 miles/hour
Speed for next y hours = 50 miles/hour
x = 1
Required
Find y
To solve this question, we'll make use of:
[tex]Distance = Speed * Time[/tex]
For x hours:
[tex]Distance = 60miles/hour * x[/tex]
Substitute 1 hour for x
[tex]Distance = 60\ miles/hour * 1\hour[/tex]
[tex]Distance = 60\ mile[/tex]
For y hours:
[tex]Distance = 50\ miles/hour * y\ hours[/tex]
[tex]Distance = 50y\ miles[/tex]
Given that total distance is 210 miles;
We have that:
[tex]Total Distance = 60\ miles + 50y\ miles[/tex]
[tex]210\ miles = 60\ miles + 50y\ miles[/tex]
Solve for y
[tex]210 - 60 = 50y[/tex]
[tex]150 = 50y[/tex]
[tex]y = \frac{150}{50}[/tex]
[tex]y = 3[/tex]
Hence,
y = 3 hours

find three consecutive even integers if the third is 8 less than twice the second
Answer:
8, 10, 12
Step-by-step explanation:
Because they are even there is a whole number x so that (1st)2x, (2nd) 2x+2, and (3rd)2x+4 are the 3 consecutive integers.
so
If the third is 8 less than twice the 2nd then:
3rd = 2 (2nd) - 8
2x + 4 = 2 (2x+2) - 8
2x + 4 = 4x + 4 - 8
2x + 4 = 4x - 4 Add 4 to each side
2x + 4 + 4 = 4x - 4 + 4
2x + 8 = 4x Subtract 2x from each side
2x - 2x + 8 = 4x - 2x
8 = 2x Divide each side by 2
8/2 = 2x/2
8/2 = x
4 = x
No we plug into our equations to find the integers.
2x = 2(4) = 8
2x + 2 = 2(4) + 2 = 8 + 2 = 10
2x + 4 = 2(4) + 4 = 8 + 4 = 12
So our integers are 8, 10, 12

A parallelogram has a base of 10 centimeters and a height of 4 centimeters. What is the area of the parallelogram?
Step-by-step explanation:
Area of a parallelogram=base×height
=10×4
=40cm^2
The area of the parallelogram is 40 square cm if the parallelogram has a base of 10 centimeters and a height of 4 centimeters.
What is parallelogram?In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
It is given that:
A parallelogram has a base of 10 centimeters and a height of 4 centimeters.
As we know:
Area of a parallelogram = base×height
Area of a parallelogram = 10×4
Area of a parallelogram = 40 square cm
Thus, the area of the parallelogram is 40 square cm if the parallelogram has a base of 10 centimeters and a height of 4 centimeters.
