Sarah and Nathan each picked a bucket of strawberries. Sarah picked 4 1/4 and Nathan picked 3 3/4. How much more did Sarah pick than Nathan?

**Answer: 1/2 buckets **

**Step-by-step explanation:**

Sarah picked 4¹/₄ buckets of grapes and Nathan picked 3³/₄ buckets.

To find out how much Sarah picked more than Nathan, simply subtract Nathan's buckets from Sarah's.

First convert the fractions to improper fractions:

4¹/₄ = 17/4

3³/₄ = 15/4

As the have the same denominator, you can directly subtract them:

= 17/4 - 15/4

= 2/4

**= 1/2 buckets **

**Answer:**

46

**Step-by-step explanation:**

110+6x=386

**Answer: 46 times**

**Step-by-step explanation:**

Since $110 is the constant and 6 is the coefficient because it is changing with each time he rents a tennis ball. The equation is **110+6t=386** where** t** in this case can represent **(return groundstrokes)**

110+6t=386 solve for t

6t=276

t=46

So he can return ground strokes 46 times

**Answer: The second one**

**Step-by-step explanation:**

Decrease £843 by 91% rounded to 2 DP

**Answer:**

Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

91% = 91/100 = 91 ÷ 100 = 0.91.

100% = 100/100 = 100 ÷ 100 = 1.

Decrease number by 91% of its value.

Percentage decrease = 91% × 843

New value = 843 - Percentage decrease

Calculate the New Value

New value =

843 - Percentage decrease =

843 - (91% × 843) =

843 - 91% × 843 =

(1 - 91%) × 843 =

(100% - 91%) × 843 =

9% × 843 =

9 ÷ 100 × 843 =

9 × 843 ÷ 100 =

Absolute change (actual difference) =

Calculate percentage decrease:

Percentage decrease =

Alex only keeps ten pence coins and some twenty pence coins in

his coin box. He has a total of 18 coins which amounts to £2.30.

Work out the number of ten pence coins and twenty pence coins

in Alex's coin box.

Answer:

In the box. we have 5 20 pence coins and 13 10 pence coins

Step-by-step explanation:

Let the number of 10 pence coins be x and the number of 20 pence coins be y

The sum of these numbers is 18

Thus;

x + y = 18•••••••(i)

Writing the value in pence only

£2.30 * 100 = 230 pence

Now we have that;

total 10 pence coin amount = 10 * x = 10x

Total 20 pence coin amount = 20 * x = 20y

10x + 20y = 230

x + 2y = 23 •••••••(ii)

from ii;

x = 23-2y

Substitute this into i

23-2y + y = 18

23-18 = 2y-y

y = 5

Recall;

x + y = 18

x + 5 = 18

x = 18-5

x = 13

An isosceles triangle has an angle that measures 118°. Which other angles could be in that isosceles triangle? Choose all that apply. a 69° b 31 c 118 d 54

**Answer:**

**b. 31.**

**Step-by-step explanation:**

The other 2 angles in the triangle are congruent so they are:

(180 - 118) / 2

= 31 degrees.

The **possible **measure of two similar angles in an isosceles triangle could be ** b. **31 °

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and **Isosceles **triangle.

We know in an isosceles triangle two sides are equal and angles **opposite **sides to the equal side are also equal.

We also know that the sum of all the interior angles in a triangle is 180°.

Let, The similar angles be '**x**'.

Therefore,

**x + x + 118 = 180**

2x = 62.

x = 31°.

.The measures of the angles of a triangle are in the extended ratio 6: 1: 5. What is the measure of the largest angle?

**Answer:**

90

**Step-by-step explanation:**

Ratio = 6 : 1 : 5

Angles are 6x ,x , 5x

Sum of all the angles of the triangle = 180

6x +x +5x = 180

12x = 180

x = 180/12

x = 15

Largest angle = 6x = 6*15 = 90

does anyone know the answer ??

120 ..................

**Answer:**

I would assume 13

**Step-by-step explanation:**

It is an isosceles triangle and all the angles are the same, so I think it should be 13. I may be wrong, it has been a while since I did geometry.

The blueprint for an office building uses a scale of 2 cm.:3.5 m. The height of the actual office building is 259 m. What is the height of the office building on the blueprint?

**Answer:**

150 cm

**Step-by-step explanation:**

So the scale is 2 cm on the blueprint = 3.5 meters in real life.

Basically you can just divide the height of the building by 3.5 meters:

259/3.5=75

There are 75, 3.5 meters in 259 meters

Since 3.5 meters on the print is 2 cm

You need to multiply the number of 3.5 meters by 2:

75*2=150

150 cm

I need help ASAP!!!!!!

**Answer:**

1. YES 2. NO

**Step-by-step explanation:**

1. Since x=0.121212... and the question is asking for 100x, we need to multiply each side by 100. 0.121212... multiplied by 100 is 12.1212... So YES, 100x is still a repeating decimal.

2. 12.121212... minus 0.121212... would just be 12. This is because if we know that all the numbers behind the decimal point is 0.121212 and so on, 12.121212... minus 0.121212... the numbers behind the decimal would cancel out. So we are left with 12. So NO, the answer for 99x is NOT a repeating decimal.

D = 24.1 cm (to 1.d.p)

**Step-by-step explanation:**

Using Pythagoras Theorem:

B: 4^2 + 3.5^2 = 28.25

square root 28.25 = 5.3 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle B = 12.8 cm (to 1 decimal place)

D: 10^2 - 6.5^2 = 57.75

square root 57.75 = 7.6 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle D = 24.1 cm (to 1 decimal place)
