What does the variable r represent in the equation 10r+4=8
Answer:
The value of variable r in the equation [tex]10r+4=8[/tex] is [tex]\mathbf{r=0.4}[/tex]
Step-by-step explanation:
We need to find the value of variable r in the equation [tex]10r+4=8[/tex]
Step 1: Write the equation
[tex]10r+4=8[/tex]
Step 2: Subtract 4 on both sides
[tex]10r+4-4=8-4\\10r=4[/tex]
Step 3: Divide both sides by 4
[tex]\frac{10r}{10}=\frac{4}{10}\\r=0.4[/tex]
So, The value of variable r in the equation [tex]10r+4=8[/tex] is [tex]\mathbf{r=0.4}[/tex]

Answer:
13. 9.77 inches (rounded to 3 s.f.)
14. 249m² (rounded to 3 s.f.)
Step-by-step explanation:
13. To find the arc length, the formula is the angle of the arc out of 360° multiplied by the circumference of the full circle. Circumference of circle: pi × r × 2
[tex]\frac{80}{360}[/tex] × pi × 7 × 2 = 3[tex]\frac{1}{9}[/tex]pi
= 9.77 inches (rounded to 3 s.f.)
14. To find the sector area, the formula is the angle of the sector out of 360° multiplied by the area of the full circle. Area of circle: pi × r × r
[tex]\frac{285}{360}[/tex] × pi × 10 × 10 = 79[tex]\frac{1}{6}[/tex]pi
= 249m² (rounded to 3 s.f.)

Jack delivered 90 circulars in 20 minutes. At this rate, how long will it
take him to deliver 135 circulars?
Answer:
30 minutes
Step-by-step explanation:
135 = 90 + 45
45 is half of 90
so 20 + half of 20 which is 10 = 30
HOPE THIS HELPS
PLZZ MARK BRAINLIEST

Students collect information on objects which change position due to a push or a pull. What is eh best unit of measurement to use when recording an object's change of position.
Answer:
Meters
Step-by-step explanation:
The position of an object is its location at a given time. Which is subjected to change with respect to time, especially for any object which has potential energy.
In the standard unit of measurements (SI unit), it is required that distance which is a measure of length is recorded in meters. Thus, the best unit of measurement to use when recording a change in the position of an object is meters.

Describe other strategies that you can use to make comparisons
Answer:
If common denominators allow us to compare fractions just by looking at the numerators, then common numerators should allow us to compare fractions by looking only at the denominator.

slope intercept form.Please help
Answer:
y2-y1/x2-x1 = 3-3/4-(-6) = 0/10
y = mx+b = 3 = 0(4) + B = B = 3
y = mx+b = y = 0x + 3
Step-by-step explanation:
If you know two points on a line, you can use them to write the equation of the line in slope-intercept form. The first step will be to use the points to find the slope of the line. This will give you the value of m that you can plug into y = mx + b. The second step will be to find the y-intercept.
Mark's soup recipe makes 6 servings and uses 4 carrots and 2 potatoes.
Drag carrots and potatoes into the box to show how many Mark needs for 15 servings
The answer is 5 potatoes and 10 carrots.
Please enter this into desmos.com/calculator (a virtual graphing calculator that is awesome) and the x-intercept will be your answer.
Simply enter [tex]\frac{6}{2}=\frac{15}{x}[/tex] into one equation and [tex]\frac{6}{4}=\frac{15}{x}[/tex] into another equation. The x-intercepts are your answers, so [tex]x[/tex] = 5 and [tex]x[/tex] = 10.

help me please gggg
Answer:
theres no question
Step-by-step explanation:
Can someone explain and answer this please?
Answer:
It's C
Step-by-step explanation:
it's c because in the triangle you can see the lines of congruence. Letter L only has only one and so does y. both x and n have 2 lines of congruence. and m and z have 3.
LNM goes to YXZ
notice how the first letter goes to the first letter of the second triangle and so on
LNM goes to YXZ
LNM goes to YXZ
LNM goes to YXZ
The letters order correspond to each other..

graph the line -1 passing through the point (-4,5)
Answer:
Step-by-step explanation:
If you want to find the equation of line with a given a slope of which goes through the point (-4,5), you can simply use the point-slope formula to find the equation:
---Point-Slope Formula---
where is the slope, and is the given point
So lets use the Point-Slope Formula to find the equation of the line
Plug in , , and (these values are given)
Distribute
Multiply and to get
Add -1 to both sides to isolate y
Combine like terms and to get the answer
So the equation of the line with a slope of which goes through the point (-4,5) is:
which is now in y=mx = b form where the slope is m=-4/5 and the y-intercept is b=1

4 pts Question 3 Justify the reason for similarity in the triangles below with a similarity postulate. 9 3 5 15 M AA SSS Not Similar SAS < Previous Next
Answer:
SAS
Step-by-step explanation:
Here, we want to check for if the triangles are similar
Firstly, we notice a marked angle on both triangles
This shows that we have an angle that is similar in both triangles
Also, if we check, we can deduce that the bigger looks like a scaled version of the smaller one to a tune of 3
This means that the sides of the smaller when multiplied by 3 gave the bigger
since the sides are in proportion, then the triangles are similar. It is not alone that the sides must be equal; once they are in proportion, then the triangles are similar triangles
Each dimension of a parallelogram is multiplied by a positive number n. Write an expression for the area of the new parallelogram. Let b represent the base and h represent the height of the original parallelogram. Expression for the area of the new parallelogram:
Answer:
Area of the new parallelogram = n(b × h)
Step-by-step explanation:
Area of a parallelogram = Base × Height
Let
b = the base
h = the height of the original parallelogram.
Each dimension of a parallelogram is multiplied by a positive number n.
Write an expression for the area of the new parallelogram.
Area of the new parallelogram = Base × Height
Base = b * n
bn
Height = h * n
= hn
Area of the new parallelogram = bn × hn
= n(b × h)
Area of the new parallelogram = n(b × h)

Kelly divided of 5/7 a liter of plant fertilizer evenly among some smaller bottles. She put 1/5 of a liter into each bottle. How many smaller bottles did Kelly fill? Pls help
Answer:
3 bottles
Step-by-step explanation:
Given that :
Total liters of fertilizer = 5/7 litres
Amount put into each smaller bottle = 1/5 liters
Number of small bottles filled :
Total liters of fertilizer ÷ amount put into smaller bottles
5/7 litres ÷ 1/5 litres
5 /7 * 5 /1
= 25 / 7
= 3.57
Hence, 3 bootles was filled
