Find the area

Answers

For height of garden we can use Phytagoreaan Theorem :

h² = 25² - 7²

h² = 625 - 49

h² = 576

h = 16 m

Area

= 1/2 × base × height

= 1/2 × 14 m × 16 m

= 7 m × 16 m

= 112 m²

4/5 of the money collected from a fundraiser was divided equally among 8 grades
What fraction did each grade receive?​

Answers

Answer:

1/10

Step-by-step explanation:

your equation is 4/5 divided by 8/1.

Lets solve that problem with the acronym KCF, or

Keep

Change

Flip.

K: "keep" the first fraction, or the one you are multiplying with, so 4/5 stays the same.

C: "change" the division sign to a multiplication sign, so 4/5x8/1

F: "flip" the second fraction, so 8/1 becomes 1/8.

now our equation is 4/5x1/8. If we solve that, we get 4/40, which reduced is 1/10.

Arnold had $37 to spend pens & pencils. The pens were $1 more than the pencils. He Bought 1 pen and 3 pencils. How much did the pens cost

Answers

The pens cost $10 if the total was $37

Work:

Pen: ||||||||||
Pencil: |||||||||
Pencil: |||||||||
Pencil: |||||||||

Basically the division groups you probably learned in elementary.


Because the question mentioned that pens were $1 more than pencils. Pens automatically start with one extra in sorting.

9(3) + 10
= 37

(9+9+9) + 10
= 37

Above adding everything together to get our answer.

Find the measure of each missing angle

I’ll give BRAINLEST!!

Answers

Answer:

angle 4 = 115°[vertically opposite angles]

angle 2+ angle 4=180°[linear pair]

angle 2+ 115 = 180°

angle 2 = 180°-115°

angle 2=65°

angle1+angle2+80°=180°[sum of all angles is 180°]

angle1+65°+80°=180°

angle 1 + 140° = 180°

angle 1=180°-140°

angle1 =40°

angle2= angle5[vertically opposite angles]

angle7+angle5+61°+90°=360°[sum of all angles of quadrilateral is 360°]

angle7+ 65°+ 61° +90°=360°

angle7+ 211°=360°

angle7=360°-211°

angle7=149°

angle7+angle6=180°[linear equation]

149°+angle6=180°

angle6=180°-149°

angle6=31°

angle4+angle6+angle3= 180°[by sum of all angles is 180°]

115°+31+angle3=180°

146°+angle3=180°

angle3=180°-149°

anble3=41°

write the equation of the graph in slope intercept form


(3,-3) (-3,-5)

m= -4​

Answers

Answer:

y = -4x + 9

Step-by-step explanation:

Slope intercept form is:

y = mx + b

If m = -4

y = -4x + b

Plug the values of the first set of coordinates into this:

y = -4x + b

-3 = -4(3) + b

-3 = -12 + b

Add 12 to both sides of the equation to isolate b:

-3 + 12 = -12 + b + 12

9 = b

So that makes the slope intercept form:

y = -4x + 9

What is the solution to the inequality 1 2/3 > r - 7/12

Answers

Answer:

r ≤ 2 1/4

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Rewriting Fractions

Step-by-step explanation:

Step 1: Define

1 2/3 ≥ r - 7/12

Step 2: Solve for r

Rewrite:                    5/3 ≥ r - 7/12

Isolate r:                    9/4 ≥ r

Rewrite:                    r ≤ 9/4

Reduce:                    r ≤ 2 1/4

Here we see that any number r less than or equal to 2 1/4 will work as a solution to the inequality.
